[MOD] Camera - Image/Video/Audio Bitrate Increases for Best Quality [NEW PROFILES!]

I AM NOT RESPONSIBLE FOR ANY NEGATIVE IMPACTS OR CONSEQUENCES ON YOUR PHONE IF YOU SO CHOOSE TO USE THIS GUIDE.
It had come to my attention that recording for long periods of time will result in large file sizes when using my mod. For this reason, I have now created different profiles to increase quality in either images or video/audio, including a new experimental version!
It has been stated that stock 1080P video runs around 20Mbps on the G2 (I consistently have 30Mbps). These mods can increase 1080P video to approximately 40-50Mbps. 720P, images, and audio Kbps can also be increased to max potential. The following steps help you unleash the best quality on the G2 camera!
WARNING: INCREASED BITRATES MEANS MORE STORAGE SPACE IS TAKEN UP.
PREREQUISITES
1) You MUST be rooted.
2) You MUST have recovery installed.
3) Download 1 of 6 media profiles:
media_profiles.xml (Increases to Image/Video/Audio)
media_profiles.xml (Increases only to Image)
media_profiles.xml (Increases only to Video/Audio)
media_profiles.xml (Stock)
media_profiles.xml (Experimental - Further Increases to Image/Video/Audio)
media_profiles.xml (Experimental - Further Increases solely to Image)
NOTE: I have tested the experimental Image/Video/Audio version. The image is a tad bit better. The video seems more stabilized and averages around 45Mbps. Audio stays about the same.
4) Download either Jishnu Sur's version 1 or version 2 mod (I prefer version 1). He now has version 2.5, 2.5.1, and 2.5.2, but only 2.5.2 has been successfully tested with my mod.
5) Download the stock file to revert from Jishnu Sur's versions.
MOD METHOD #1 (RECOMMENDED) - Requires most files from above.
1) Place all the downloaded files somewhere in the phone.
2) Boot into recovery.
3) Flash the stock zip.
4) Reboot system.
5) Boot back into recovery.
6) Flash the Jishnu Sur mod downloaded.
7) Reboot system.
8) Use a file explorer (like Root Explorer) app to open the folder where the downloaded media profiles file is.
9) Rename the media profiles file to be "media_profiles.xml".
10) Copy the media_profiles.xml file.
11) Navigate up to the root folder and go the "etc" folder.
12) Paste the media_profiles.xml file.
13a) A message may appear asking for rewrite (R/W) capability. Select "yes".
13b) A message will appear asking to confirm overwriting the current version. Select "yes".
14) Reboot the phone 1-4 times.
INSTALLATION METHOD #2 - Requires only the media_profile.xml and Stock file from above.
1) Place all the downloaded files somewhere in the phone.
2) Boot into recovery.
3) Flash the stock zip.
4) Reboot system.
5) Use a file explorer (like Root Explorer) app to open the folder where the downloaded media profiles file is.
6) Rename the media profiles file to be "media_profiles.xml".
7) Copy the media_profiles.xml file.
8) Navigate up to the root folder and go the "etc" folder.
9) Paste the media_profiles.xml file.
10a) A message may appear asking for rewrite (R/W) capability. Select "yes".
10b) A message will appear asking to confirm overwriting the current version. Select "yes".
11) Reboot the phone 1-4 times.
REBOOTS: The reason for the last step is that it needs at least one reboot (but probably two) to increase the quality of video. The images should already be at their highest quality.
AUDIO ISSUES: If the issue where audio can no longer be heard occurs, it has been confirmed that going back to stock and repeating the steps fixes this.
QUALITY INCREASES: I found that after at least one (as many as four) reboot I was getting extremely high video bitrates; between 38Mbps and 50Mbps! The image quality should increase above stock as well as above Jishnu Sur's mods. Audio increases between 190-210Kbps.
MOD DIFFERENCES: I found a few differences in these mods. Jishnu Sur's version 1 seems to help with focus and a few other things. His version 2 adds to his first by restricting high ISO or low FPS in low-lit areas. His newer versions decrease bitrates. My mod increases the quality of images and videos above Jishnu Sur's, but does not have the other features.
PREVIEW OF IMAGES AND VIDEO: Here is a large zip file of images I took while testing. There were an abundance from my reboots, but I only chose one set per folder since the file is almost 70MB!
HOW TO CHECK QUALITY:
Images - Check the storage sizes of two or more images. Open an image in Preview or any viewer that can zoom. Zoom in on the curtains. Open the other image(s) for comparison and perform the same amount of zoom. Compare the clarity (sharpness) of the images.
Video - Check the storage sizes of two or more videos. Right-click on a video and click Properties. Click the Details tab. Check the bitrate of the video. Right-click on the other video(s) and perform the same actions. Compare the difference in bitrates.
A quick lesson on Lighting (ISO, FPS, Exposure): The higher the ISO the more light for the camera, but with more noise in the image. The lower the frame rate (FPS) the more light for the camera, but less smoothness for video. Exposure can help you compensate for images (or parts of images) that come out too bright or dark. Exposure should be used when optimal ISO or FPS settings have been found and changing them will alter quality in some manner.
Credits: Jishnu Sur for his mods.

nice man. just flashing his mod now and your media profiles..i'm excited!

Can you post some examples of before and after the mod?

Sorry to hear that. Just went back through my test files of video and each one I created had audio (The Simpsons were playing in the background). I am not sure why this is not working for you, anyone else with this issue?

You should not have to create a SkyDrive account as I have it open for public download. I logged out of my account, tested it, and I had no problem accessing it. Please check again and reply if the problem persists for you.

"NOTE: Flashing other Media Profiles may loose the quality as the camera.msm8970 is synced with the Media Profile."
i wonder if flashing this mod would've actually made it worse bc of that?

I'm a bit confused, his mod, or mine? If the audio occurs after his (it doesn't for me), you can try my mod without his. My mod is purely for quality increases. I have done this for other phones before and never lost audio.

I have no audio either...

I would have to say no just from the test files I have. I think the statement refers to media profiles that have yet to be altered (stock settings), which would definitely bring down your bitrates (back to stock).

ah. what i did was flashed his mod, then pushed your media profiles and lost all audio.
also, the videos that were recorded with your media profiles didn't work correctly on my PC. they would freeze up and wouldn't play right...then i went back to his media profiles and it worked fine. weird.

Okay, now were getting somewhere. It is odd this works for me without issues, but not for you. One thing I can think of is I flashed another zip at the same time when flashing his.
Maybe you can help diagnose this issue with me. First, what variant of G2 do you have (I assume an American carrier)? Second, would you be willing to undue his mod and try just my mod to see the results? These two things would tell me a lot about what is happening...

From another thread a user modding the media_profiles didnt see any changes to vids and images r u sure it works for anything except for codec checks? Make sure the modded apk, libs and media_profile all match with the same bitrate and settings perhaps.

These can be hit or miss on different phones. On my S4 changes to the media profile would not take if replaced. I could change the values in-file and they would stay, but the quality would not change at all. On my ZTE U950, the file would indeed change and improve.
This mod works with more than just the codec checks, here are a few simple reasons why:
1) You can check the audio in the my media profile. The audio in the file is at 320Kbps, however, the video file for preview is a bit above 192Kbps. So this should disprove that only codec checks are being done since the audio is not being pumped up as high as I would like (yet).
2) The video storage sizes are also different, and if they were at the same bitrates (even if the codec read differently) the sizes should be similar since they are of similar length and content.
3) I performed some basic math to determine what percentage of my Jishnu Sur preview video is compared to my preview video. How does this help? If the storage size and bitrate percentages come out about the same, then the codec should be displaying the correct information since the storage sizes can't be incorrect. Both came out to about 83%. I can provide this simple equation if people wish to check for themselves.
I do welcome the question and any others people may have. People should make informed decisions before using mods.

Hello,first i want to thank you for your work.I have the Korean F320S model and i have the same problem with audio too.I dont think its model dependent as it seems.I did the same as the other guy,flashed the other mod and after that pushed your profile in.Im willing to help with the issue if you have something i can try.

[Q] Remove shutter sound on rooted H815

is there anyone there have found a way to disable the shutter sound on the g4 ?
have tried to rename the system files but no luck the sounds might be imbedded in the camera apk ?

Renaming is enough. You have to kill the camera one to have an effect.

You say you've renamed the system files and that wasn't working and your solution is the same as what's not working?

Silent files seems to be a solution. But why? There has to be a sound file, somewhere hidden. When I delete the startup ogg, the sound is gone. So why not with the cam ogg's!?

I hate to bring back old threads but it's better than creating another one for the same exact question:
I just got another G4, h811 and rooted, trying to disable the camera shutter, i've renamed all files at first and nothing was working, the shutter still persists, then i went and delted all the camera files in the 'system>media>audio>ui folder, and rebooted the phone, and checked back inside the folder, the files are gone, but the camera shutter still persists! All the camera sounds are still on, the autofocus, the click, and the shutter sound. What gives??

Deactivation of HDR+ shutter sound not working

Hi guys,
i don't like most of the sound any smartphone does when doing any kind of stuff.
So i simply deleted all sounds in system/media/audio/ui.
Since goolge is putting some sound of their camera app (for example the HDR+ shutter sound) in the apk file itself i modified this, too.
I opened it with winrar and replaced any .ogg file with an empty one.
Afterwards i deleted the .odex file of the google camera and also cleared the dalvik cache with TWRP.
The camera app is still working so i guess everything went well.
But the HDR+ shutte sound is still there
What am i doing wrong?
I'm kind of clueless.
Thanks for your help!

Audio recording lacking bass

Hi, I am running ressurection remix 8.1 on my whyred ai, cant seem to work out how to get any bass on my video recordings, on my mido I had to flash some changes to audio mixer files etc. Not sure if anyone else is having this problem but the audio reoding sounds really tinny.
anyone else notice this?

just realised the inbuilt audio recorder is ok, only video apps like google camera and opencamera seem to have the issue?

Ok found a way to get really good audio quality. I've searched across boards and tried a lot of stuff. The volume level might be low(er) but I need to alter another XML file. Good enough for concerts and out in the open I would say.
First you need to change the max bitrate since they set that to 96KHz which is way to low. The file to edit is /vendor/etc/media_profiles_vendor.xml
Almost all the way down that file you see the AAC settings.
You will see
<AudioEncoderCap name="aac" enabled="true"
minBitRate="8000" maxBitRate="288000"
minSampleRate="8000" maxSampleRate="48000"
minChannels="1" maxChannels="6" />
As you see I set it to 288000.
Next is the biggest issue. Seems the MIUI camera standard uses AGC and that high pass filter that up to date I haven't found. Open camera works but the other microphone you can select they go via the noise cancelling stuff which kills the audio and you get an underwater sound.
I have a official licensed cinema FV-5 from the playstore. Now there is an issue for the moment. I cannot record in 1080P (the image zooms in like crazy it seems, I contacted the developer for that). On 4K recording it works perfectly. Also remember in the menu to tab the little shaky hand to switch on the stabilizer as that works miracles.
Now go to the settings - audio - audio source is set to 'built-in mic(video camera)' ------ audio channels - stereo (2) ----- bitrate - 256000 ----- sampling rate - 48000 and very important 'disable audio automatic gain control - is switched on' meaning disabled.
Give it a go.

@junglist @lukesan Hi,
I downloaded Mi Max 3 ROM which is the same SOC and I found some interesting stuff about that!
mediaprofiles.xml in vendor is the same on both devices (at least on 9.5.19.0 which am using right now) but the one in system is different, on Mi Max 3 they changed the aac bitRate in so many lines from 156000 to 192000 which is looks interesting!
Also there’s a trick here, mediaprofiles.xml which is in system is the same media_profiles_vendor.xml which is vendor, same on our device, that means both files must be overriding not only mediaprofiles.xml in system!
here’s a flashable zip from Mi Max 3 ROM for any one wants to give a try, also check out this video which compares between our device and Mi Max 3 regarding this part:
https://www.youtube.com/watch?v=5LKThf9KWjs (09:42)
I still need to perform more testing before I can confirm if this really works or not!

Ok, very cool find! Observations which I made over the last couple of days
We have 2 'issues' on the redmi note 5 (Whyred) so 1) the bitrate and 2) the highpass
1) is as you say media_profiles_vendor.xml we can easily alter that one. Check out the downloadable MI MIX 2 audio quality ... module for Magisk. Download extract and copy that xml file and set the same permissions 644 I believe. Make a backup of the original first. They set the bitrate really high on that one 256kbit/s I believe which is a bit overkill, but compared to 20mbit/s for the video it is nothing and I rather have overkill than 96kbit/s underwater sound.
So that one is easily fixable.
2) The high pass filter seems to be linked to the AGC. I really like the AGC since it keeps the volume constant and should be the standard for the 'normal' people who do not care about extreme hifi things. I would leave it on if I could only switch off the high pass filter. Shoot a video and it will be perfect for 99.999% of the people. Levels will almost be perfect. People easily understandable etc etc etc.
I would like to switch off the AGC (and the filter) for real audio recordings, meaning classical music etc etc .. this involves always having to check if your level is not to low or if the peaks are not to high causing clipping which means distortion.
For issue 2 the only app that I found that can do this is cinema-fv5. I made an error in my previous text to set it to 8MP since then the stabilization doesn't seem to work properly so I now set that to 2592x1296 which seems pretty 16/9 like to me. If you switch off the AGC in this app then you get AGC off and high pass off. Very low level audio but perfect quality. I guess perfect for a concert. (this weekend there is a local festival here so I can really test (and enjoy))
If you want good audio but mono then you need open camera for now. If you set the microphone to 'mono' you will also hear that the sound is good, setting it to stereo gets the noise cancellation working and it sounds like crap.
I'll try those Mi Max 3 things if I find a bit of time. Lets share knowledge and experience and we'll get it working like it should. This is the only small downside of the redmi note 5 that I have found so far. (and that is coming from an S7)
---------- Post added at 10:54 AM ---------- Previous post was at 10:00 AM ----------
@rocker00 Just flashed it. Does set the bitrate to 288kbit/s which is really high but, like said above compared to video that is peanuts. Better a lot more than what it was. But it does not switch off the AGC or high pass. Since you have the rom can you check and attach another file? The file is in the same path (vendor/ etc) our file on the redmi note 5 is called mixer_paths_skus.xml . I guess it might be a bit different on MI MAX but I guess some more audio is being controlled there.

@lukesan First please override media_profiles_vendor.xml manually because it looks like the script is not mounting vendor!
Regarding the file, media_profiles_V1_0.xml, mixer_paths_i2s.xml, mixer_paths_mtp.xml, mixer_paths_skus.xml, mixer_paths_skush.xml, mixer_paths_wcd9326.xml, mixer_paths_wcd9335.xml and mixer_paths_wcd9340.xml
are the same md5! but mixer_paths.xml (which i downloaded the whole rom just to get it in order to try to enable dual speaker) is completely different!
Also i have 2 doubts:
1- in build.prop which is in vendor they changed ro.vendor.audio.sdk.fluencetype to fluence which is none in our device(related to noise cancelling)
2-ACDB (Audio Calibration Database) which is completely different in Mi Max 3 cuz it has dual speaker and two speakers at the bottom, and ACDB is controlled by audio.primary.sdm660.so which is different for sure in both, i hope it's not related to that because it will be really a hard job!
here's the mixer_paths.xml am still looking into it maybe i can find something!

Probably it is taking the media_profiles_vendor.xml which I already edited manually. Well to check that our device is capable you could check with Cinema-FV5 lite which is free up to 1280x720 resolution. Disable the AGC and you get a nice clear sound full audio spectrum. I'm on a 8.7.5 rom and when I start to record my image is taken from the upper left corner all zoomed in. Not sure which rom you are on, but could you give that a try?
If it's that *.so file we need to address someone with the right knowledge. I've never decompiled stuff like that.

Just came back from the festival that I told about. The default MIUI video cam.. wow made a complete mess. The AGC went completely crazy and no bass. Using cinema-FV5 ... wow listening to it right now with my earplugs..... it's like I'm still there. Ok the bass sounds (only) a bit distorted, but I was standing at the front and the smart people there handed out headphones that dampened sound to the kids. I myself suffer from tinnitus so I have -20dB earplugs ... even then it was crazy loud.
So cinema-FV5 is definitely a must with music. Not sure if I can upload something on Youtube without violating copyrights. But surely this phone is capable of recording high quality audio for sure.

Same happened to me. After recording the stage with artists and loud music. It looked OK, stabilised video at 1080p, but sound lacks bass with stock camera app.
I would like to try better camera apps like gcam, just there are ~50 hours for me to wait till I can unlock my bootloader and flash a decent ROM.
Then we could record at 60fps 1080p and [email protected] with normal audio.

Forget gcam or other roms for now since they use the same audio path. There is another trick I read about but it involves a lot of work and I would hardly call it a working thing unless you spend a lot of time. Check this thread. I know for the MI MIX but same procedure applies for now. https://forum.xda-developers.com/mi-mix-2/how-to/mi-mix-2-video-sound-recording-quality-t3776450
Leave the 60fps and 4K behind if it is in a dark environment. You might end up with dropped frames etc which is really annoying.

Have you tried it? I've tried your trick with the bitrate increase in media_profiles.xml, though I've set it to 192000 and used the FV-5 disable the AGC and it's much better quality! Although the bass is a bit too much pronounced and the meds and highs are a bit sacrificed, it's still much better than stock. But with the custom settings for audio in FV-5 it makes that "underwater" sound, no matter which combination I used, but I did everything according to your post, only if I leave the default values it works. (I now suspect it was maybe because of the stereo recording option)
I am interested to make some changes using the thread you linked, I'm just afraid not to make a mess of volumes in earpiece or introduce echo during a call or something like that, that's why I'm hesitating.
The AGC makes a total mess of recording, it lowers the quality and introduces background noise.
For the 60fps I'm not sure that works as none of the camera app that I've tried are able to record it (I'm on AOSP based rom) because it depends on the camera blobs, and I'm not sure Xiaomi updated the sources, but they did introduce it in MIUI 10 builds.

Have you tried it? I've tried your trick with the bitrate increase in media_profiles.xml, though I've set it to 192000 and used the FV-5 disable the AGC and it's much better quality! Although the bass is a bit too much pronounced and the meds and highs are a bit sacrificed, it's still much better than stock. But with the custom settings for audio in FV-5 it makes that "underwater" sound, no matter which combination I used, but I did everything according to your post, only if I leave the default values it works. (I now suspect it was maybe because of the stereo recording option)
I am interested to make some changes using the thread you linked, I'm just afraid not to make a mess of volumes in earpiece or introduce echo during a call or something like that, that's why I'm hesitating.
The AGC makes a total mess of recording, it lowers the quality and introduces background noise.

Strange that you got the underwater sound. Can you check with this one? https://mediaarea.net/en/MediaInfo Just drag and drop the file on it. It will show the audio properties.
Just to confirm again my settings in FV-5 I changed the resolution to 2592x1296 (turn on handshake thing on where you can actually see where you are recording, weird setting I know). In the 'Audio' settings check the attached screenshot.

Oh yes I did that, but you didn't check the "Custom audio settings" box so the app uses default system settings rather than the ones you selected. Try it out if you didn't already.
And I've checked with MediaInfo, the video was recorded in 96K (because the app didn't use custom settings), but anyway it should be using maximum possible values the device has set in media_profiles_vendor.xml, which is in my case 192K. I've seen now that media_profiles_V1_0.xml is basically the same file and there is 96K set as maximum, maybe both files need to be changed?

That's normal since it seems you can't overwrite those settings in our current roms it seems. I bought that FV5 but I emailed support and never gotten answer back, to bad. It always takes the settings from that file on the phone it seems. And yes if you see 96Kb/s than it is normal that you hear these metallic sounds. Can you maybe attach the media_profiles_vendor.xml you have in the /system/vendor/etc dir?

Well recording in 96K instead of 48K which was the case with MIUI 9.5 in GSMArena test is already an improvement, however I'm sure this device is capable of even more. So for now, seems that just disabling AGC made a very good difference, it might just get better if we raise the bitrate even more. I've seen in the thread you linked that they actually modified media_profiles_V1_0.xml in case of LineageOS to raise the bitrate, I will now try that one as well.
Here is my file you requested.

I confirm that changing the media_profiles_v1_0.xml does increase the bitrate! I have set it to 192K, however since the maximum value that was set for each resolution (I've tested 1080p) is 156K the app used that one based on previous setting. Now every app should use the 156K if we don't alter the bitrate for each resolution separately (that's my guess at least).

Just came back from the festival that I told about. The default MIUI video cam.. wow made a complete mess. The AGC went completely crazy and no bass. Using cinema-FV5 ... wow listening to it right now with my earplugs..... it's like I'm still there. Ok the bass sounds (only) a bit distorted, but I was standing at the front and the smart people there handed out headphones that dampened sound to the kids. I myself suffer from tinnitus so I have -20dB earplugs ... even then it was crazy loud.
So cinema-FV5 is definitely a must with music. Not sure if I can upload something on Youtube without violating copyrights. But surely this phone is capable of recording high quality audio for sure.

I tried this app with the steps you mentioned and yeah, sound is better for sure but it's much better if we can get the same result on stock cam.
let's take it step by step, first is the bit rate, even after using Mi Max 3 files the bit rate remains the same! i checked my old Sony Xperia z2 mediaprofiles.xml and i found the aac bitRate is also 192000, see the video sample result in the 1st pic from sony and second one from note 5 pro!
Now clearly there's something controlling the cam audio beside mediaprofiles.xml since the modifications wasn't enough!
I'll record a log while recording and let's see if i can find any info about that!
@Cirra92 60 FPS is working on 9.5, i thought like you about blobs but surprisingly no! now i'm on 9.5.19.0 and i just got the camera apk from MIUI 10 and i have 60 FPS!
Also i found another thing which is interesting but it's still not working even on Mi Max 3.....looks like 120 FPS HFR is on the way!
Check this video out: https://www.youtube.com/watch?v=0rjZx_5JD1s (13.06)
I managed to get this setting even if it's still grey!
etc\device_features/whyred.xml just added those lines:
<!--whether support camera video high frame-->
<bool name="support_camera_video_high_frame">true</bool>
let's try to make the cam perfect as much as possible!

How to properly Record Video on festivals?

I cant properly Record videos when loud music is involved. The sound is way too loud and muffled.
Is there any solution to this.
On stock camera and Gcam noice cancellation is being used making it sound even worse.
I found out that in Open camera choosing "unprocessed" in sound options fixes the things a little but still

Unfortunately not really. It seems that they simply screwed up the settings for ACG (automatic gain control) and audio drivers regarding video audio recordings. Most of the Xiaomi devices suffer from that. They do not care about that. It´s such a simple and basic function for a smartphone and I´m sure that hardware used could easily handle high gain audio inputs like on concerts or festivals, but the settings and config they choose to give us simply cripples the device.
It´s a shame really. There is a camera app called Footej Camera that allows you to adjust the input gain settings for video - that could be worth a try.
Also, if you´re rooted and are experienced with modifying system files you could try to modify mixer_path files to get better results. See for example thread: https://forum.xda-developers.com/redmi-note-5-pro/help/audio-recording-lacking-bass-t3814184
