Excited about possible video recorder cab from the Xperia X2

I know that we can get better quality video recording out of the TP2, with the first WinMo phone shooting WVGA @ 30fps with the exact same hardware (minus cam module), I'm excited to see if someone can work their magic to incorporate better recording from the TP2.
Anyone else?

I too am curious about this. I have actually always been curious as to whether the video capabilities are more software dependent or hardware... Though if the phone is capable of displaying the video on the viewfinder at WVGA at 30fps it should theoretically be possible to record at that quality. Anyways, we'll see what crops up later

Not at all

Unfortunately the above statement is not at all true. Recording depends heavily on the camera hardware in terms of possible frame rate at a given resolution. Furthermore real-time compression and encoding is a significantly different proposition to the CPU than decoding and playback. This is not to say the TP2 hardware may not be capable of doing better than it does, just that playback capabilities are no indication.

Like I said, I don't know how much the camera module affects it. And what I meant by theoretically is that if it can display that on the viewfinder at that res then theoretically it could be recorded in raw format (as long as the transfer to the memory could handle the speed), but it would not be practical by any means. But if the x2 is capable of it and IF the ONLY difference is the camera module, and IF the camera module is just the sensor and no graphics processing then it could possibly happen. And I'd love to see it. But neither am I going to hold my breath.

You see minutes 4:29 ..... But WVGA recording resolution is 720x480? or 800x480?
Thanks

The Xperia X2 has the same CPU as the Rhodium and in theory the video recording abilities can therefore be ported. The drivers for video recording must be extracted and put into the Rhodium ROM.
Even if the Rhodium camera or drivers doesn´t handle WVGA widescreen recording it´s possible with some development work to use better encoding drivers - i.e record VGA but let a good MP4 encoder with good quality do the encoding job (i.e replace the original HTC video encoder with a better one).
In this case the original HTC camera application is retained but with replaced encoders. The user only sees a quality difference - the handling of the camera app is the same otherwise.

That's definitely be a good thing. Maybe it could even up the fps a little bit.

Well if we can get someone on that I'd be willing to pay (big - ROM COOKERS LISTENING?? :-D ) for the capability to enhance the video recording capabilities. I just need an additional 10 fps and maybe another 200 kb/s bit rate for excellent video. That would make the video recorder to 30 fps @ ~ 1Mb/s..niiice.
If they can accomplish WVGA or even D1 (720x480) that would be cool too (or better).
I wish I had the skills/tools to do that, I'd be all over it like white on rice! LOL
Cyph

Personally I don't need 30fps (though it'd be nice). I'd be happy with a video standard such as 23.976fps or whatnot. 20 does look stuttery. Just a few more would fix that. Well. Let's hope someone looks into it. Though it might be necessary that we wait until the x2 is actually released

Recording video to h.264 codec on Evo?

This question is for developers. Can devs replace crappy compression codec on Evo recording cam to record with h.264 to improve quality of vids we shoot by far. Current cam codec is SO bad that 720p does no justice for the cam. Basically in my view camcorder is useless. H.264 would change the whole game for this phone. Would love to see the rom with h.264 video camera codec. Would any shead some light on this ?

Do you even know what the current cam codec is?
It's MPEG-4 Part 2 (generally referred to as "MPEG-4"), which is most commonly known for it's implementations in divx/xvid.
It's not as trendy as H.264 (aka MPEG-4 Part 10 and/or AVC), but generally quality isn't what people take issue with when choosing h.264 over MP4 - it's filesize. When you get into higher resolutions with higher bit-depths, being able to compress a stream allows you to work around issues with slow write speeds.
I think you really aren't familiar with video encoding or codecs in general. You should educate yourself a bit more before announcing that a simple codec change will resolve the camera woes with the Evo.
h.264 is currently patent encumbered, which is part of why you don't see it implemented so widely.
Swapping out the codec isn't going to be a magic fix to improve this camera. It's limited by it's very design. Consider the 720p video a novelty and try to only shoot in situations with lots of ambient light and it'll be far more usable.

I agree with you. But x.264 is not involved in any patent issues, is free, and works very will with the best container format available to date... mkv.
Now the phone will do hardware decoding of x/h.264 but you are right, I don't see any advantage other than the smaller file size. You are right again, on one of those P labeled cams the h.264 stream is much smaller than that of mpeg-2/dvd or others so it works well on those crappy hardware writers.
Changing the encoding profile of this camera would not fix your issues OP.

I've never seen bad quality from h.264 codec but then again i agree i have not research enough on the codecs comparison enough but that's why i'm asking. I just know it looks horrible. Somehow camera pics are acceptable. Thank you for the input.

I could encode an h.264 video in a low bitrate and low resolution and it would look bad. The codec is only one factor involved in the end result. Different codecs can squeeze better quality video into a smaller file size but it comes at the expense of CPU use and other bottlenecks. In this case I don't think the choice of codec is what is holding back the video. It's probably more about processing power and overall architecture.

I'm not sure that implementing x.264 compression for the EVO would solve anything. From my experience in order to have better quality with h.264 over h.263 it requires much more processing power due to the higher compression complexity.. This would all have to be done real time by the phone.
With the great hardware being sported by the EVO I wonder if a more unorthodox approach could be implemented to attain the highest quality possible.
How about this:
Capture video using a real time lossless compression. Maybe huffyuv?
Once captured let the phone recompress the source to x.264 or whatever via a background service or at a scheduled time like 3am or something
Maybe via this method a higher frame rate could even be achieved?

Uncompressed [email protected] with 8-bit color would be something like 45MB/s. (That's excluding audio.)
No current SD card supports those write speeds.
I'm not sure that you could losslessly compress it down to something that'd support even a class 6 card.

Eeeeek!!
I checked it out and you are right on the money.
(8 bit @ 1280 x 720 @ 59.94field = 105 MB per/sec) / (2.33:1 huffyuv) = 45.06
Still I wonder if better video quality could be achieved via a capture now (large file size) compress later (small file size) solution.
Certainly, considering your well taken point, we would need to keep things within the requirements of the EVO's hardware (sd card included). Probably would need to keep the data rates within the EVO's stock microsd specifications in order for it to be viable for everyone.

The iPhone 4 can record in h.264 and its processor isnt *that* much more powerful than Snapdragon (and the camera is similar--same company, same sensor size, same features, just 5MP instead of 8MP). What it comes down to is lazy coding by HTC

I don't know if you guys have looked in the build.prop file but the settings are in there. I just don't have alot of time to play with them but here's what's inside. Sprint/HTC changed the line in 1.47,ro.media.enc.vid.m4v.bps, to 8000000 from 6000000 on 1.32, so I'm guessing that's how they upped the Mbits in the upgrade. I could be wrong and the change may need to be in the kernel also but play with them and see.

I may not be a...
developer but when you are talking about codec you are talking my language (I am an editor). H264 isn't that great itself and won't make the EVO's footage look any better yeah you get some more detail out of the H264 but the real reason the camera doesn't look as good is the variable fps in different lighting conditions. The variable kills it. The cam should be fixed at 24fps or 30fps. If that can be done you will see a major difference. I'm not sold on the white balance either. Also I would love to have h264 but the difference in the two is compression. H264 is better but again FPS is key.

I agree as well as most of the other people that h.264 won't help by itself.
Though one thing it would help with is allowing to bump up to a higher bit rate and or FPS and still maintain speeds sufficient for Class 2 SD cards. So, even though it won't do anything by itself, it will help in that you could in theory record higher quality video to your phone.

Das troo, I emailed Omnivision about the issue, they said that their Evo is great there, and that I should contact HTC about it and had said they created the driver/software for it.
"Hi Steve,
I’m sorry to hear that you are experiencing issues video performance. The HTC EVO we have here works great. OmniVision only makes the sensor. HTC makes the drivers and software that run the sensor. Unfortunately, you will need to contact them with any issues.
Sorry, I couldn’t be more help.
Scott"
Then I had asked them if they have any samples they used. And sent me a video they just recorded.
"We just went outside and took this simple video. Hope it helps.

480 fps Slow Motion at 720p Possible?

Hey all. So far I'm loving this phone!
I saw that OnePlus updated their 6 to enable 480 fps super slow motion video a while back, and since this is also a SD845 phone I'm wondering if Asus can also add this option to the 5Z?

Hey friend.
The ZenFone 5z's Soc can take up to 960fps
but there's no Dedicated RAM(DRAM) for camera to process that kind of frames.
for example: Sony Xperia XZP's camera has a DRAM with 128MB and high frequency (don't remember the number).
anyway, Try some other camera UI apps that may work.

Yeah I know what it is capable of, was just wondering if it might be possible for Asus to add the 480 fps at 720p option through an update like OnePlus did. Thanks anyway.

Bumping this thread back up.
Read yesterday that Xiaomi is sending an update to the Poco F1 which enables 960 fps slow motion video. As far as I know the Poco was never mentioned with having support for this sort of feature when it was launched. Any thoughts on this?
I'm going to contact Asus and see if they are going to include at least a 480 fps option since 960 fps requires different hardware (like RAM for the sensor).

Best video recording app for Redmi Note 7

So GCam is definitely the answer for getting the best photo quality out of this phone in almost any situation, but let's see how we can record the best possible video.
Btw, when you first try video recording with the Note 7 in low light, it's natural to be disappointed since you're comparing it to GCam's photo output in low light. GCam uses frame stacking and other techniques to remove noise, increase dynamic range and get details in both shadows and highlights as well as the rest of the image. To produce only one 12-megapixel frame, it uses anywhere from 3 to 15 frames and takes a few seconds to do the complex blending and computations to create a great low light photo. Without a much stronger SoC, ISP, a better sensor and more advanced processing algorithms, this is impossible to do while recording a video, as the phone is struggling to keep up with recording 30 8-megapixel frames (UHD) each second or 2-megapixel frames in case of 1080p. They've barely managed to get SD 660 to comfortably use real-time EIS at 1080p30, along with auto focusing, WB, exposure, noise reduction etc.
So, knowing that in low light this phone's video recording will never be great, let's focus on other aspects of its video recording. My only idea for improving low light video recording is to find an app that can use a high bitrate in order to avoid introducing additional noise and artifacts. This also applies to filming in daylight.
I'll start with some findings about the differences between the stock app, GCam and Open Camera when recording video.
STABILIZATION
As far as video stabilization goes, only stock camera's 1080p30 EIS properly uses gyro-EIS and that really is the most beautiful stabilization you'll get out of this phone. No wobbling or image distortion, it just softens the shakiness, as if the phone were on a gimbal.
1080p30 EIS in GCam – it's instantly noticeable that the viewfinder here is stabilized (whereas in the stock app it isn't). It appears to be using the gyroscope, but not in the same way the stock app does. Stabilization is OK, but not as smooth as in the stock app and wobbliness can be noticed occasionally, with more abrupt movement.
UHD EIS in GCam – better than no stabilization, but wobbliness on the edges tends to be obvious when there's a lot of movement.
1080p30 or UHD EIS in Open Camera – also a stabilized viewfinder, but the stabilization algorithm here is very wobbly, which is extremely noticeable in UHD, so try to hold the phone as stable as possible when recording in Open Camera. The highlight of Open Camera for the Note 7 is its front-facing camera UHD stabilized video recording. So far this is my only use case for Open Camera on this phone (plus testing).
If you like using 1080p60 because of its smoother panning and movement in general, here's a tip to stabilize 60 fps videos: shoot in 1080p60 without EIS in the stock app or another app (using a high bitrate when possible) and then stabilize the footage in Google Photos, which does a nice job unless the video is impossibly shaky.
SLOW MOTION
In my testing, I've never managed to get a smooth slo-mo video out of the stock app and I've tried it after every MIUI update so far. At 1080p or 720p, the result is always a stuttering slo-mo video. GCam to the rescue!
GCam can record stutter-free 1080p slo-mo for a long time (I tried it for a couple minutes) and the resulting video is smooth as butter, suffering only from an occasional hiccup here and there. Perfectly usable.
Open Camera can also record in 1080p120. Different apps should be tried out to see how smooth the slo-mo is and which one is able to use the highest bitrate, leading to the highest image quality. Although image quality does appear to be limited in slow motion mode.
FIELD OF VIEW (FOV)
If you have your phone on a tripod or you can lean on a surface to stabilize it, you should turn EIS off. This will give you a wider field of view and a sharper image. When you're recording a video, the top and bottom portions of the image are cut off to accommodate for the widescreen format. This already makes you lose around 25% of the image information that the sensor can actually see. EIS works by further zooming into the centre of the sensor (or cropping the image) and using the now-extra information to shift the frame in any direction as necessary, to produce an impression of a more stable footage.
The phone will not recognize that it's on a tripod and turn EIS off. You have to do that manually. Why would you want to do that? If you want:
1) to capture more of the scene (a wider field of view), with EIS on, you'll have to step back (which is sometimes not possible)
2) better image: stabilization comes with trade-offs. If you don't need it, turn it off. The phone will be able to use a greater number of pixels to create your fixed-resolution video, resulting in a better image.
With 1080p30 EIS off or UHD without EIS, you'll have the widest FOV possible for video on this sensor. Only top and bottom are cut off for widescreen.
1080p60 EIS off – for some reason, this has just slightly narrower FOV than 1080p30 without EIS. The same FOV appears to be present in 1080p120 (slow motion).
When EIS is on, it crops the least on the stock app, slightly more on GCam and the most on Open Camera.
VIDEO AND AUDIO BITRATES AND QUALITY
Work in progress. So far I can only tell that stock and BSG's GCam produce different videos. Stock uses a higher video bitrate and GCam a higher audio bitrate. Open Camera tends to put on a yellow cast, presumably to make the image warmer. Also, bulkin's GCam allows you to select video bitrate. Haven't played with that or the bitrate in Open Camera.
It's also worth to test other apps, such as Cinema FV-5. I've had luck with that on previous phones.

Very detailed observation.. Thanks for sharing. ?

Have anyone tried 'Footej Camera'?

Great post. My recomendation for all uses is gcam, not the best in all but not the worst. Perfect for a daily use

There is a possibility to set the video bit rate in some of the other GCam MODs.
I can recommend this GCam MOD made from developer marlin-ku OR this GCam MOD which have much more valuable options (speed / ISO optimisations) from developer bulkin043. The last version of the second MOD is available in the Telegram channel here.
This port is the best working - one of the few other GCam MODs I'm frequently using on my Redmi Note 7.

is it is also true for 4k30 ? do you getter final image quality and stabilization if you do eis in google photo as it must be a more complex algorithm vs "eis on" that only must use a simpler faster algorithm that runs in real time
is it hardware accelerated by the snapdragon 660's Spectra 160 ISP or is it software running on the arm cpu (question both for " eis on" and for stabilisation done in google photos app )

Google photos stabilization is good, sometimes it does a miracle, but some artifacts appear in the video. It's more aggressive and intelligent than eis on but quality could be not so good. (I don't know anything about which processor is used, but in Google photo is a lot slow the stabilization process, about the double of the video duration)

video quality difference between 4k and 1080p on bsg mod
i installed this gcam mod : https://f.celsoazevedo.com/file/cfiles/gcm1/MGC_6.2.030_RN7_V1a_FINAL.apk but i notice that 1080p and 4k have a completely different look (different WB, different DR) is it due to snapdragon 660 limitations ? is gcam only configuring the hardware capture codec for snapdragon 660 hardware or is it applying some software computation (google proprietary code) on each frame in real time ?

Best video camera app for me is open camera. I do 1080p with 120 fpS with that and it's awesome. Other one is filmic pro. I can shoot flat video and chose nitrate and frame rate.

Okay, I've than that... Thanks

My best is filmic pro. It is dedicated app for video making. U can record in flat/log profile which u then can color grade later on.
The quality is greater than other app.
Open camera is also nice but it has less control over the video. U can't control color temperature and u can't basic color grade ur videos. Plus u can't save ur preset.
I have no luck with GCam and stock one.

Pics GCam, Video Stock
Interesting Thread. On MIUI Global 10.3.6 and now MIUI Global 11.0.4 (Android 9) using GCam PMGC_7.0.009_Astrophoto_Version_V12 overall I'm impressed, activated Sabre and H265/HEVC (edit/play/upload compatibility seems good for the apps I mostly use which paired with the smaller size is good). Not sure if really but crispness/clarity seems well improved as well as less speckles/red-dots especially on the skin in artificial/low light. EIS also still very good.
I also use the stock camera and OpenCamera, so what bothered me in GCam PMGC:
a) still focus flickering in video (can it be optimized by any settings?), stock RN7 camera IMHO has considerably less such flickering?
b) needing GSF: so no CustomROMs? Or is MicroG able to solve this?
c) found no possibility to save to SD-Card DCIM, I think in PMGC V3/V4 versions this still was available?
For OpenCamera while b) und c) are no problem regarding a) there seems to be good micro movement EIS but overall movement/transition is not so smooth; focus seems manual (tapping on-screen) so I could not see flickering . I like OpenCamera for the many settings especially the filename without prefix. It is also possible to set RAW DNG or WebP (I use 4x3k JPG 84%), Exif tags, HEVC, 24 fps, flat/log profile. I wonder why half-max-res pics (2000x1500) are not available to select. For video I would like to have something 16:9 slightly bigger then FHD so like 3K (2560x1440) which is not available (only 4:3). I also can not find timelapse.
A friend has Filmic on RN7. It has pro options and as well HEVC. As i tried once EIS is ok (below stock/GCam) and it seems video focus flickering is noticable just a little more then Stock and GCAM is considerably worse. I do not like the 1/3 screen Play preview of taken videos (just 3 show up) and also the files are not saved in the standard DCIM camera folder on the SD (CMS External Storage, not found by Gallery Apps).
Currently my preference is:
Images: GCam PMGC
Video: RN7 Stock; Timelapses: GCam PMGC

Hi everyone! Back to this topic to ask you a question. After the recent upgrade to Android 10, still with MIUI 11, I've noticed that
- stock camera has video stabilization working "after save"
- gcam (tons of version tried) and opencamera have no more stabilization. Once it was directly on the screen. Now there's any noticable on the screen or offer save.
Do you have the same problem? Thanks! Any way to solve this?

4k Video Recording & Hdr in @25MP mode using OPEN CAMERA

Hello everyone,
》 You can use "4k video recording & click @25mP images in hdr mode" which isn't natively present in the stock camera, period, by using "Open Camera"
》Playstore Link : https://play.google.com/store/apps/details?id=net.sourceforge.opencamera
》I saw a marginal improvement in highlights especially at the night time shooting where stock camera blows up the highlights almost all the times & the detail levels are also higher as the image is captured in @25mp mode with active HDR.
》There's no stabilization in 4k recording but i saw drastic Improvement in dynamic range, especially at night. The difference between the stock 1080p video & the 4k video from "Open Camera" is huge. Ofcourse the files sizes are also 4 times higher.
》The details are much higher in both the front & back camera with better dynamic range using "Open Camera" especially during daytime.
》I prefer the stock camera only to capture still images at night due to faster shutter speed & as A50 uses pixel binning in 3:4 hdr mode which helps to gather more light ofcourse. The images are comparable here, though in this situation only.
》》》 If you're going to record video at evening & night time, I highly recommend you using 4K option in the "Open Camera", trust me the difference in dynamic range especially at night is unbelievable.
》》》 Tip : Keep the scene optimizer on & use 3:4 hdr mode while shooting at Night on Galaxy A50 as it uses pixel binning & AI to get stable pictures & gather more light for a bright shot. Avoid wide angle lens at night.
》》》 Reply to this post if you want to see actual proofs else you can try it out yourself.
Here's 4k vs 1080p video sample link (uncompressed)

The more interesting thing is what the phone is actually capable, but isn't enabled in the stock camera. Maybe Samsung will optimise the camera in future updates.

Yes brother, exynos 9610 is infact capable of doing [email protected] as mentioned on their official website.
Also, Galaxy A50 has flagship grade imx 576 sensor :

I doubt that Samsung will add 4k in future updates.

Hi, everybody. I'm using an Open Camera that's unlocked, it will unlock the camera at 2API.1280x720 resolution, bitrate 200 mbbs.120 frames per second, but the video size is 398 megabytes in 18 seconds.

xda turns into a resource to read instead of humor. The man took and unlocked camera2api without even realizing what it was. On a rooted a50, it does not allow access, but he succeeded with a finger movement in the settings ...

help! what's the settings in open camera to make 4k video?

Nothing.
Change the resolution to 4k in Settings > Video Settings > Video resolution
You're good to go, Cheers.
