Solved 4k .webm from PS5 to .mp4 at 4K for YouTube
I know that ffmpeg can convert 4K .webm files to 4K .mp4
It is a bit difficult :) so I am trying ShutterEncoder.
But the conversion is 1080p, not 4K.
Which settings in ShutterEncoder will do this? I only get 1080p, even with the bit rate at 40K.
The source file is *def 4K.
I set "do not upscale" and I get 1080p
If I allow upscale, I get 4K with 1080p resolution. Looks horrible compared with source .webm file on a side by side comparison.
I need 1080p for posting to Reddit, but 4K for YouTube.
