[htc camera] improving video recording quality/bitrate

hello,
I have found a location in the registry where you can change the bitrate which is used while recording videos.
registry path:
hlm/software/htc/camera/recparam/mp4large
dword name: bitrate and vsbitrate
my problem: descreasing bitrate takes effect but not encreasing the bitrate.
example: I tried to set the bitrate from 384000 to 768000=~768kbit/s but the recorded mp4-file has only ~320 kbit/s instead of ~768kbit/s
the camera settings are correct chosen, because by decreasing the bitrate for example to 128000 the video quality gets lower.
try it out, it works.
it would be nice the improve the video quality by trepassing the presetted 384000 bitrate border...
what to you think?
any idea how to get it working?
thanks & greetz

my guess is that the encoder can only encode so much video at the same time, the write speed should not be a problem at all though.

i9000 media_profiles.xml CM10.1 framerate reduction for brighter videos in the dark

Hi, I want to create another profile in media_profiles.xml (or edit existing one, 480p for example)for recording in dark environment.
I succesfully changed audio and video quality, but I can't decrease framerate for brighter videos (camera FCor I can't press record button). I know, that is possible - http://forum.xda-developers.com/showthread.php?t=1583259 (yes yes, stock rom and another variation od i9000 series, but this mod is based on the same thing as I wrote - brighter videos by lowering framerate .. and it works - I had this phone before)
quote:
If you limit the framerate to a minimum of 30fps, the video can become very dark when there is not enough light. If you lower this limit to - say - 10 fps, the video will be brighter in low light, but it will be "laggy" and because each frame is exposed longer than at 30 fps, blur will be more likely. Both is inevitable, but in my opinion still better than a black video
I will be grateful for any help, it is really important for me, because I often organizing a underground parties,
and I want to promote it, so I'm doing a video report from them and... audio quality is superb (better than S3 or S4!),
but (as I said - underground parties) it is dark, there is only a strobe, small light for artists and nothing else, so ... almost nothing can be seen on my recordings

improve camera

sony camara give picture with much compression, and its affect a quality and definition
i found a program camara, that can give a picture with a 100% quality a think
in play store "vignette"
BEFORE TAKE A PICTURE
IMPORTANT!!
configuration! vignette
resolution 13 megapixeles
quality
superfine
effects
no efects
and important
Auto save = 2 seconds
and the pictures now are excelentys

Using professional camera apps like filmic pro or Cinema 4K

Hello,
I'm on the latest OTA update and I can't use these apps.
Filmic pro does not allow me to use 24fps (always goes to 30fps). When I choose the Force FPS option it does 24fps (but this is experimental). My videos shot in 4K are worse in quality than 1080p in native camera app. I talked with the support and they said that i'm the only one with P20 Pro with such a problem. Did any of you use this app and had such problems? Can you share a sample video?
Here is my sample from filmic pro (1080p and 4k video): https://we.tl/s-q5TPnIuzJg
In Cinema 4K it never records in 24fps, and the app crashes every time I try to use flat color profile.
Is my device broken?

b u m p

filmic is not using camera SDK for huawei ( or something like that)
you cannot use 3x zoom camera only main one and if you compare 4k filmic and 4k native (other camera app) 100% crop filmic looks like upscaled 1080p- quality is much worse.
i am using open camera app - at least i can use zoom camera and bitrate is decent 80mbit (max what p20 pro supports).
but whend testing the phone and shooting grass while walking (lot af moving objects) biterate is around 100mbit, when shooting static picture with some pans bitrate is 40-60mbit. i was using 150mbit hevc on galaxy s7 and it is always 150mbit in the dark when recording fast scenes or static objects. with huawei i want high bitrate in night scenes to reduce compression artefacts because of high iso and phone lowers it actualy which is dissapointing.
this phone is very bad for video. old galaxy s7 was much better and has ois.
for photography it is okif you use raw/ bw camera bud also here compression is too high. but actually i think it's only phonefor now that can bring output quality bit closer to nokia 808 output.

Thanks for the reply - that's sad that "the best camera phone" is that hard to use.

Question Samsung camera mod

I found that using screen recording while using samsung camera app in photo mode makes the field of view wider compared to video. And dynamic range is better also.(forget 4k). But good for social media sharing.. but the only problem is the zoom toggle in the way. Is there any way to remove that toggles.. maybe a modded apk or something???...

I think it's because when the camera is in photo mode, the app uses the whole sensor. This means that it is recording with a resolution of 3000x4000 pixels (3:4 aspect ratio). But when you record 4K, the camera app uses only a portion of the sensor equal to 2160x3840 pixels (16:9 ratio). That is the reason you see a wider view in the photo mode and not in the video mode. The only solution right now, might be to use OpenCamera to record video but you have to select the 3:4 ratio in the video settings. If you do that though, OpenCamera will only film with a resolution of 1440x1080 so the video will not be that sharp. I admit, I would love to see a mod or a toggle from Samsung that lets you record in 3:4 though.

Thanks. But what about the hdr.. i mean i have tested it and the hdr performance with ultrawide camera in screen recording is great compared to normal video capture. Even in low light the screen recording looks way too wider and brighter and had great dynamic range. (I have also tested shoooting in 1:1 in video). Kindly test it out and see it yourself. But don't pixel peep it's obviously less crisp than 4k. But great for social media.

I see what you mean. Video from screen recorder is a bit different from video mode. However I do not know why this happens. I suspect that maybe screen recorder is not able to capture the whole color gamut of the HDR preview.
