I'm not good with this stuff, so please dumb things down as much as humanly possible and assume that what I type is probably all i know about ffmpeg.
Okay so I rendered a 1080p video as thousands of 16 bit png images.
I want to take these images and create a 10 bit h.264 video file with either a matroska or avi container. I'll need to add in a .wav file as the sound without re-encoding as well. I'm guessing I can just use this command at any time to do so after its in mkv format in this example: ffmpeg -i original.mkv -i audio.wav -c copy output.mkv
So this is what I have so far: Note I have no idea what the input for PNG images is so I just left it as "input" as you see below. When I do the command below on a normal video file it uses 8 bit. So I need to know the command to specify 10 bit.
ffmpeg -i input -c:v libx264 -preset veryslow -crf 0 output.mkv
(1) ffmpeg -i input.mkv -i audio.wav -c copy output.mkv (2) ffmpeg -i input.mkv -i audio.wav -acodec copy output.mkv (3) ffmpeg -i input.mkv -i audio.wav -c:a copy output.mkv (4) ffmpeg -i input.mkv -i audio.wav -vcodec libx264 -acodec copy output.mkv
Which of these 4 is the best to use if I JUST want to combine video with audio without re-encoding? or is there an even better one to use?I was told -acodec copy is necessary to ensure it doesn't re-encode, but others have told me differently. should I use -acodec copy instead of -c:a copy?
