Hi,
I’m adding an .mp4 file to the timeline with proxy enabled but the proxy generation fails. Any ideas, I was thinking maybe VBR?
I can proxy with ffmpeg (extract from VS C#), with the following as an example on the same file:-
process.StartInfo.Arguments = " -y -i " + “\u0022” + src + “\u0022” + @" -vf scale=w=-2:h=360:flags=bicubic+accurate_rnd+full_chroma_inp+full_chroma_int -codec:v mpeg4 -g 5 -qscale:v 8 -c:a copy -y " + “\u0022” + dst + “\u0022”;
Here are the details from Shotcut 20.10.31
