Better Recoding Video Quality with XPERIA CAMERA

Hi brothers, now I wrtie to ask if somebody knows where is the register entry for the xperia camera, I think i found it but it won't show all the entries that the HTC cameras show. The HTC cameras registry entries has all detailed on different folders like JPEG settings, medium quality video, high qualitity video, and stuff like that.
Well, I think that I have the solution for the bad quality video of the xperia when you shake o move your phone, I think you know that I mean. You see always pixelation, and that have various reasons. One is that the video format is very bad quality for, it's only 3GP and we don't have a choice like other HTC Cameras when you have MP4, CIF and other formats. Other reason is the video's bitrate and THIS is our solution.
If we can turn up the bitrate of course we'll have better quality in the videos and we can see especialy an improment in scenarios like sports when we have to move the phone very much. Of course, that bitrate increment become the video more heavy but that's something we have to deal with because the quality worth it.
Other solution is find a way to change the video format to H264 or MP4 and combine the bitrate idea with this video format too.
I have been making some experiments but no luck yet. Any ideas?

Nobody?
I'm sure that somebody can post one good idea. Come on people, you guys make the best HTC's roms and more, I don't think you have no idea about solving this. Somebody?

I think its Sony+HTC problem, not something that belongs to here ...
just like u can't have smile shutter, same ways, u can't change recording format ... may be some time in future, Sony might add support for h264 recording in firmwares, just like they added auto flash and geotag in leaked R3AA/R4AA rom.

Thanks for the reply
Thnaks for the answer! You are totally right in every point BUT I think that waiting is not an option for me because I bought the Xperia almost replacing my HTC TyTN + Sony Camera. I like to record almost all the concerts I go and the Xperia is the right option if we can make some camera improvements. I think if someone give me the xperia camera source code I can do everything by myself, or at least that is that I have in mind
Even, I think we can make a few changes for the camera to allow to zoom when recording video (if somebody haven't done it yet..).
In other hand, where can I find the R4AA rom? I didn't know that was already out. Again, thanks for the reply!

there is no r4aa. he was refering to unknown sourced leaked camera app with geotagging and auto flash, which supposed to be present in r3aa, but never was actually.

zoom facility in the video recording of the xperia is a very welcome step...hope somebody smart enough in the xda forum look forward to it...

I think it could be done, because the camera app uses a system file to access the camera, then it uses a video or picture encoder to produce a picture or a video. If somebody change the encoder and set the new parameters or settings into the camera app i think that it will work.

Exactly
And I'm your men, I wanna do that, but I have to view the source code or something. Where can I find it? Anyone on this forum can give me a hand to start working? Thanks!

I think that the better way is create a new camera app and add lots of features and then sell the app to a company like spb.

hahah nice one, Good luck with it.
if the wanted to make it a camera phone then the wouldn't put wortless camera in it. i wonder why sony didn't put better camera in it like SE k versions my old k750 has better camera .

use higher bitrate in camcorder

So i was tremendously disappointed to find my snapdragon beast of a phone to only record video with 8000hz audio. I'v been searching for ever and it seems like no one wants to remedy this. am i the only one that would like audio that doesn't sound crappy? Is it possible to mod the apk to allow for higher bitrates? Possibly 44100? Or can some one write an app to do this? i am sick of the 8000hz.

Hardware limitation perhaps?

Codec limitation.

Yes the audio is piss poor right now.

[request] Audio Quality Fix during Video Recording (Auto Mic Gain Control?)

Would love for someone to be able to implement this fix either into an app or a kernel possibly. I can't stand not being able to record live music or really even anything with loud ambient noise/bass/variable sounds. The Video is pristine, the audio makes it completely unusable for anything.
I'd be willing to start a bounty for this.

I have the some problem, recording audio is useless right now!

Anyone? I need this also

if anyone knows of a way to do this, it would be awesome!

I was reading the s2 forum on this found a app called Hi-q that has a mic gain control, however its just a audio recording app. Wish there was a camcorder app that has the same function.

bump
has anything come up in the past months to improve this ? I just went to a gig yesterday and came back home with great video with farting sound
saw something about GNex Toolkit having some mods for sound but I think it only runs on Windows ? (it's an .exe file). However if it's a mod I guess the specific mod can be extracted and installed on the phone using adb or whatever..

bump again...this must be annoying a lot more people

bump, still need this

Me too.

Would be nice...
Glad to find this one - Sad that there is not really a simple solution yet... bump

i just cover the mic with my finger while recording in loud environments it works for me xD

[Q] Increase video and audio recording quality? Build.prop anyone?

So I can't post in the development section yet(I was going to ask in the relevant thread instead of wasting a new one on this question), which I think is a nice rule, but I'm starting to delve into UNDERSTANDING development and how it works. So anyway...
If someone actually checked out this post(which I doubt, since I don't really see people checking the Q&A section) I just wanted to ask, is the build.prop file what I should be looking at for this? I'd like to point out the the EVO 4G has AWFUL audio recording quality, the video I can stand. Just the audio is terrible and totally unnecessary. 12.2kbps at 8kHz is just unacceptable when we have apps utilizing up to 44.1kHz WITH THE VERY SAME MIC that the camcorder uses. I don't know the bitrate for that recording app, but I imagine its at least pushing 96kbps. I used to check "No Audio" and record audio with one app then use the camcorder for video, which was a hassle because then I had to edit the files and put them together.
Yes I know the EVO isn't a GREAT beast(single core processor) but that doesn't mean anything when you got similar phones well within it's realm of spec(DROID, Epic 4G, iPhone 3, etc.) with camcorders that BLOW the EVO out of the water. Why did HTC fail to acknowledge that this was an important issue?!
So enough ranting, my question is simple. The things that are edit-able in the build.prop file include video recording quality and audio recording quality. Does that mean that the EVO's crap camcorder and camera are limited PURELY BY THIS SINGLE FILE? Or, are there other hardware and software limitations that affect the quality?
Lets say that you can dedicate ALL the power the phone has to the camcorder and its software, why should there be a limitation on the audio quality? Why is the audio quality so bad. I see people posting tweaks to increase VIDEO recording quality, and they're done in the build.prop file right? I have no idea how to test if messing with the audio bitrates and frequencies actually work, has this been tested? is that why its ignored? Please someone talk some sense into me! I heard that you gotta do a data wipe for changes in the build.prop to take effect. Is that true? is that why I never experienced differences?
And I really hope I don't get a reply saying "use the search next time" because all I found were VIDEO QUALITY tweaks not AUDIO QUALITY tweaks. Is it because they don't work? or WHAT? and also, I'm rather new to modding, I rooted a long time ago, and flashed a couple mods like a year ago, but recently I've become more interested in HOW those mods work.

There are multiple quality improving methods. Try my smurf tweaks, or xloud and bravia engine. Also there is beats audio u can add it as well. There are was to better ur phone.

Shortly after I posted this, I looked and saw another question asking for a "smurfed out script" and I thought... what the f!? Thanks, I'll check this out and the others you mentioned.
***UPDATE***
Okay, so I looked at those engines and your script. Haven't tried them yet because I don't really want to flash my phone or wipe it right now and they're more for audio and video playback than recording, but I did find a post on Android forums about this issue. Some guy suggested using the LG Camera app. So I checked it out, and I can fidle with the audio quality in there. I never new about this app, but this is EXACTLY what I wanted.
I appreciate your reply though. I probably will end up flashing your script soon, when I have more time. I know this was an old issue, but I had never found a good solution until now.

I know beats audio works. I ran the old eternity rom with the (mod edited) kernel and the audio was brilliant.
Mod edit sorry that kernel isn't allowed to be talked about on xda

? wow really? hmm(thinking about the "mod edited"). only reason I could think of a kernal that's banned in the forum is legal reasons tied to the forum(and a number of mods seem to contradict that reasoning).
I'll try beats, whenever I get the chance i guess, but again, isn't it only for audio playback? the issue I mentioned has nothing to do with the playback of videos, it's the recording. On lg camera, you can change the audio encoding to AAC and mess with the bitrates and the frequency. I have problems on my phone though, the video skips, I think it might be because my sd card is crap, i think its a class 2(its the one that came with the phone) plus its only 8GB. I think I'm gonna buy a 32GB from my friend, I think he said its a class 6, idk how much he wants for it though.

Actually due to gpl issues and with the developer....xda and the developer have come to an aggrement that his name and kernel are not to be talked about or mentioned on xda. In the future I recommend that if you do not know the history or reasons that you not speak about it.

Video Sound quality

Hey guys,
anyone else experienced bad video sound quality? I found out, that the phone saves videos with 96kbps sound, wich is an explanation why the sound is that bad. But can we do anything against it?

I too am experiencing this issue. Not sure if a fix currently exists. On another note, when I purchased this phone i was hoping for more development support! It may still be early, but not too impressed so far!!

I also just got bitten by this crappy audio when recording videos. It absolutely sucks! Will using a different camera app fix it?

I dont think so as I am already using cam mod.

There must be some audio postprocessing going on. When I record audio with an app (Easy voice recoreder) and choose microphone "Main (unprocessed)" the sound is good. If I choose just microphone "Main" the recording is very bad (the same distorted sound I get in video recordings). So the phone can record good audio. The question is how to record unprocessed sound in video.

The bitrate is 96kbps with no way to change.

Get the camera app called Lgcamera. In this app you can manually set your audio settings.
Set it to AAC and set the stereo option to On (this did it for me atleast).

soo.... to answer to myself it does not work, the audio quality is still 96kbps, I had an idea to record audio separately.
if you start recording only audio with an app like "easy audio recorder" and then you go to the video app and record. the recording audio app won't stop recording its quality is gonna change to 96kbps (bad)
EDIT: yeah, it sucks, only xiaomi can fix it.
I have found a trick to record good audio see my post below.
