Video quality problem. Video Look Worth than In Game

[shinkuan]

Here is two picture, one is from game, the other is from FFmpegOut video:

The in game one look much more better than the output video, why??

[keijiro]

Because it's compressed.

How can I not compress it?

[keijiro]

The main motive of using ffmpeg is to compress the video. If you don't need video compression, I'd recommend using Unity Recorder with the Image Sequence option.

For the details of Unity Recorder, please see the following page of the manual:

Unity Recorder

But you can only use Unity Recorder in editor. Can’t use it in builds. ?

[keijiro]

Right. Then you can try one of these lossless codecs with ffmpeg: https://superuser.com/questions/347433/how-to-create-an-uncompressed-avi-from-a-series-of-1000s-of-png-images-using-ff

You can customize the ffmpeg arguments by modifying FFmpegPreser.cs: https://github.com/keijiro/FFmpegOut/blob/master/Assets/FFmpegOut/Runtime/FFmpegPreset.cs

I tried:
case FFmpegPreset.UnCompressed: return "-c:v r210";
from

https://superuser.com/questions/347433/how-to-create-an-uncompressed-avi-from-a-series-of-1000s-of-png-images-using-ff

But the output file has 0kb, it is broken.
Sorry this is my first time using FFmpeg, how should I do it?

[keijiro]

I'd recommend checking if the argument (-c:v r210) works correctly with ffmpeg from the command line.
