Video quality/compression problems - Xiaomi Mi A3 Questions & Answers

I was testing Mi A3s ability to shoot video in low light. It appears that it cannot properly handle the recording as it compressed it to oblivion. Screen from the video:

I also tried shooting in "Short Video" mode from the stock Camera. Surprisingly, it doesn't have the same problem. Screen:
Does somebody know how to fix the default mode?

Mi A3 is a budget phone, low light video shooting quality is obviously a no-go... What kind of crazy low-light video quality would you even expect at this price range... For the price, I am not going to complain for poor low-light video quality...

Maybe I phrased that incorrectly. Both of the screenshoots come from Mi A3. It appears that in low light conditions it's "short video" mode comes out way better than normal video recording. Was just wondering if I can somehow get my normal videos to look like the ones from that "short video" mode.

Looking at codec details for both short and regular video, I am not sure how "short video" mode can capture better. It uses significantly less bitrate (8mbps at 720p) compared to regular video (40mbps at 4K)

Xperia C5 ultra Camera quality

Hi all
I'm looking for a camera app better than the one that is installed from sony.
I know that sony did not implement the camera 2 api but the pictures taken with their camera app appears blur, washed, and in general poor quality.
So I'm waiting for your experience...:fingers-crossed:
Thanks
François
I've tried a few Camera apps, but I don't think I've found one that gives better result.
As far as I'm concerned the picture quality is okay, just make sure to keep your hands steady and wait for a few seconds because this phone does have shutter lag.
If you want to shoot faster, as long as you're in good lighting condition, use the Manual mode, choose Sports scene, that'll shorten the shutter lag a little.

There is NOTHING wrong with the camera or the default software.
Quality is great, you just have to know how to use a camera, use of iso, shutter speed, etc...
I think image quality is great and I'm quite happy to post several shots should you wish.

Hi
I can confirm that FreeDcam (special build made by defcomg) allows the Xperia C5 ultra dual (E5533) to shoot in raw and save pictures as dng. Those dng pictures can be processed with Lightroom, Rawtherapee or Photoshop to get the best of the raw picture. :victory:
Here is the link of FreeDcam thread
http://forum.xda-developers.com/android/apps-games/camera-freedcam-4-0-3-t3115548
and see from post #37 on page 4. The right released apk is linked on post #57 in page 6. Some minors problems stays there but overall job is well done.
Thanks to defcomg for his quick job and the quality of the result.:good:

Should you know how to take pictures, the C5 Ultra is a very capable camera and takes excellent pictures. Here are several recent ones taken:

Question Camera presets for shooting in low light

I remember my old Xperia Z1 having amazing presets to take pictures in low light. Now, I am a proud owner of the Xperia 1 III without such luxury
Am I the only one missing those? Yes, you can play with the Shutter and the Iso to get better results while taking pictures in low light without a flash, but that takes time to do it. By the time you make all those manual settings, you would lose that photography moment...
I tried the function "S" and the function "Auto". The last one, "Auto" scored the best but way far from the presets of the Xperia Z1.
Does anyone know a way to fix this inconvenient issue? Maybe a better quick setting or some presets that can be imported? Sony...can you give us those presets with your next update??? I don't want an iPhone owner to embarrass me with its great low light pictures

Question Good third party camera app?

I find the Google camera app on the Pixel to be absolutely atrocious. The amount of sharpening and post processing that is being done is out of control, particularly on human faces... even in portrait mode. From what I can tell the only way around that are third party camera apps. What is a good one that provides manual controls and DNG shooting without the AI crap?
Update: ended up buying ProCam. As a long time slr user I find it completely intuitive but can understand how it can be intimidating for a first time user.
Open camera and Hedge Cam - These two are top quality open source camera apps. But only if you are willing to spend bit of time on understanding and experimenting with all the customization. They are completely manual. You need to turn on Camera API 2 to enable all the features.
Use the stock camera app for the usual point & shoots and use those serious apps for some serious captures and videos where you are willing to spend time in editing them in the computer or even in the phone.
If I'm taking a photo with people's faces in it, I do it by shooting in video mode, then selecting the best shot in Adobe Premiere. Thus, the resulting image has less contrast and color saturation than an image taken in photo mode.
Well, if I record a video that I want to archive like a video, so I make some adjustments there too. This is because even video taken with the stock camera app has too high contrast and color saturation. So they I apply the following effects to all the videos, the first effect is an effect called luma corrector, in which in the tab tonal range - highlights, I set the level contrast to -8 and then in the tab tonal range - Shadows I also set the level contrast to -8. This will increase the dynamic range, because I will extract some more image information from the dark shadows and from too much bright highlights.
And then they I apply a second effect to soften the intensity of the colors, which I do in an effect called lumetri color

Why I think the camera app sucks on this phone

Recently I got an Xperia 5 Mk. II because I wanted a cheap, well built cameraphone, and largely it delivered. The Photo Pro software is the best I've ever used on a phone, but the RAW output seems to be not really that raw. First off, I couldn't disable lens distortion correction on the wide angle lens, which should be disabled by default when shooting RAW. Moreover, JPEGs come out with the natural fisheye distortion, RAWs come out filtered.

On the other hand, while shooting RAW with the third party Firstlight camera app, DNGs come out exactly how they should be. But it's a buggy third party app and the autofocus is borderline unusable, especially compared to the native app.
Much the same way, another issue i came across, which also plagues the 5 III, 1 II and 1 III (although NOT the IV gen, as I've seen so far) is the telephoto RAWs. They seem to be infested with this 1px wide grid across the whole image, especially on the highlights. At first I thought it was the bad ISOCELL sensor, but again, tried with Firstlight and photos came out flawless.
(5 III and 1 III RAW samples taken from www.photographyblog.com; all images are contrast enhanced)
Worst thing about this grid problem is that it seems to translate to JPEGs as well, but in RAW it is absolutely intolerable.
And not only that, both these issues seem to persist across multiple versions of the app. I did try from 1.1 to 1.3, which is the latest one supported by my unit.
My theory about this is that these filters could be pulled out of the APK, for which i just don't have the brains to get around. I did decompile the app and found some tiny bits of glsl and some vague "pre-output correction" calls in the DNG builder that do confirm my suspicions, but i really have no clue how to navigate around this stuff any further and, well, make RAW raw again. For a phone series that prides itself on having an accurate and natural looking camera, this certainly takes a lot away from it.

Question Action / Sports shots with the default camera

What is the best way to take an action shot with the S23 Ultra? I am not an avid photographer but do want to take decent not-blurry pics from kids sports activities. Is it possible without going into RAW mode and changing exposure settings? Back in the day, my Note 8 had a "sports" mode that was easy to use though haven't seen it in a while. But I do see a "food" mode that I'll never use...
The "motion photo" setting is useful; it can only be viewed and edited with Samsung Gallery app though. The phone allows you to make gifs too.
This is on my N10+/Pie, presumably the S23U still has these options.
There's also burst mode.
Live tracking as well which may or may not be useful. Set up is rather convoluted as certain options are only available at certain resolutions, fps or with other options. Guides for other older models may be helpful if the S23U guides aren't providing enough information. Many of the features date back years.

A combination of burst mode and live tracking is definitely your best option.
I would still recommend looking into gcam using this gcam and config :
Post in thread 'Working GCAM for S23 Ultra' https://forum.xda-developers.com/t/working-gcam-for-s23-ultra.4550019/post-88277895
That version will offer face focus tracking by default which is great for kids action shots. You can also enabling focus tracking if you often need to take pictures of your kids without seeing their faces but otherwise, you want to leave focus tracking disabled so it better tracks faces. Picture quality for the time being will be better than stock cam.
In the end though, even under good light conditions, smartphones won't do miracles for action shots as their focus system isn't that fast. But I'm sure with stock or gcam you can manage some decent shots
