Better video quality? - Samsung Galaxy J7 (2017) Questions & Answers

Don't get me wrong the video quality is good, but can we push it even further like can we do something about the bitrate, make the video even sharper and better?

why is quality of video recording on the touch hd so low?

i have a blackstone almost a year and noticed that when you record a video the quality is the same as when you take a picture but if you finish it and you go look what you have recorded the quality is so bad
does someone know if it is possible to get better quality video recording
because this restriction the manufacturer HTC HTC suck
Whats is the best quality of resolution to record: L, M, S or CIF?
Thanks

720p recording and bad audio quality

I know the people here are very talented and I hope someone can help. I had high hopes for the video recording on this phone. When the reviews came out I was very disappointed in both the pic and video quality. Every 8 mega pixel camera phone out there beats it. Even the 1 year old Omnia HD. I can live with the pic quality but the video quality is what really frustrates me. Yea it records in 800x480 but whats the point if its pixelated and washed out. Not to mention the highest frame rate it can go to is 26fps. Ohh and the audio quality is horrendous. When the Omnia HD came out it also suffered from bad audio quality but in a later update they addressed the issue. Most phones coming out now record in AAC audio which the Incredible obviously doesn't. I just wish someone can up the frame rate to 30fps, give the video a higher bitrate, and change the audio to AAC. IF you have spare time can you unlock the 720p recording.

Any way to increase 720P fps?

Is there a custom ROM or even a simple app possible that can capture 720P video at LEAST 25fps for the Evo? I have yet to be able to capture anything better than 22fps. It's unacceptable. Also the audio quality is TERRIBLE. 8Khz? Seriously HTC?

HTC Phones are good but the camera is very poor. If it was recording at 25fps it would still suck... Droid X does 720p recording very well like a mini camcorder. I have HTC Desire..
I managed to get around 30fps..
Audio still poor though
But here's how you do, go to Camera(not video, photo!), change ISO -> 800 (not Auto), then -> Video recording, and it should be more stabile and higher fps.

best quality video chat app?

Hi
What apps are you using for videochat?
Everyone I try looks like crap, they are nowhere near the quality I can get on a computer with a ****tier VGA webcam when I have a 1080p much better on the phone, but every app I use it, it doesn't offer true hd quality and smooth fps, all of them looks bad in quality of image and framerate
any idea?

Anyone know a way to stop the camera from upscaling the video recording resolution?

This has been bugging the hell out of me since I got this phone. All the reviews made such a huge deal out of the phones camera quality and capabilities. But upon using it myself.. I am not all that impressed. When I record a video in say 1280x720, the resulting video always looks like it was recorded in say 800x450 or something along those lines. No matter what bitrate I choose, it looks like a lower resolution. You can't zoom the video hardly without it degrading. Go ahead, try zooming on some text in 720P. Now compare it to 720P on some other phone. Now, when I record in say 1920x1080, the resulting video looks like it was recorded in 720p, not 1080.
I have 720p videos I recorded from my Galaxy S4 that look FAR FAR better than so called 720p on the V20. It seems like the camera on the V20 is UPSCALING the video recording output to the next highest resolution than what is ACTUALLY being recorded. 720p appears as 480p, 1080p appears as 720p etc. As someone who is picky about quality, this has been a major blow since I got this phone. I am surprised no one has ever posted about this.

Iv noticed it, but I brushed it off as I felt nothing could be done to fix by me or other devs that I am/was aware of. Now that I think if it more from your words, maybe could be fixed by overclocking the 4k to 6k, or 8k, to get a 4k resolution. Need root to try this though.
Well, at least I'm not the only one who noticed. Is it the same way on Oreo? I mean, did the update "fix" anything related to video recording resolution or is it still upscaled? (I'm still on 7.0 Nougat for battery reasons, but if 8.0 has a video improvement.. well, game changer). This seems like false advertising meant to try and push 4k capability when it really couldn't. If the camera really isn't capturing 4K, then does that mean it would be too much a burden on the hardware to actually be pulling 30 4k FPS ...VS 30 1080P FPS upscaled to 4K?
Are you talking about the quality on Google photos, or the out of camera quality?
have you tried exporting it to your computer via USB? Cos, for some reason the quality and resolution are lower on G Photos.

I don't think a burden but more of how's it's coded. 4K on tripod is hard to tell vs 1080p. Note 3 was same way. Oreo cam may be better but I can't really tell. Idk why 16mp is not fully utilized for 4K 16:9 either. Coding that I personally don't know how to do. Slow mo don't even have sound via stock cam.

Camera output. That is, the resulting video file from the camera after pressing record button.
I know there is a loss of quality from compression. But it's not compression artifacts causing this. Bitrate doesn't make any difference. You can clearly see the video detail is not even close to what it says it is. I especially noticed this with text. I was recording a video while in a car. There was a car maybe 1-2 car lengths ahead. One can easily read the license plate. In the recorded 1280x720 video, I could NOT make out the plate at all. You'd thought I recorded in 960x540 or close. It's rather blurry. I think that's why LG added all that oversharpening.
I even set it to take photos at 1280x720. And even with high jpg compression zoomed/cropped, it doesn't look like the 1280x720 zoomed/cropped video of the same exact item being photo'd.
Been using Mark Harmons OpenCamera and trying all sorts of video bitrates. Then changing photo save resolution. I found that a photo resolution of between 960x540 and 800x480 (cropped) looks very similar to what a cropped 720P video appears. It seems as if there is some kind of preprocessing going on with the image that makes it appear extremely muddy (smudged blurry detail cropped). Nothing at all changed with the quality whether the bitrate was set at 5Mbps or 50Mbps. Quality remained unchanged.

Sounds like Oreo update isn't worth the trouble. As far as how it's coded... I think it's the awful preprocessing muddying up the image detail as I mentioned above. Using massively high bitrates does no good at all.
4K on tripod VS 1080 on tripod is quite noticeable on the V20 due to the appearance of upscaling (or horrible preprocessing.. whichever it is).
I didn't know Slo-Mo was supposed to have sound. I mean, the option to enable sound would be interesting (say a time-stretched audio instead of slowed down pitch).

Who wouldn't want sound with slow mo? That's like no sound with regular video lol.
LG also made it to where 4k can barely be done via third party. Gcam can't...Open Cam can. Nothing can be done without root tho. Even then... limitations upon availability and know how. Manual setting is your best bet. Auto is well...auto, so definitely postprocessing will be involved and yes it's not the best, unless fixed with some mod, even if that works. LG hardcoded lockdowns. Camera firmware can be possible tweaked...but I do not know how.
