I'm trying to reduce the size of an mp4 file to adjust it for streaming. The
video is about one minute long and I used the sample command shown in
https://trac.ffmpeg.org/wiki/Encode/YouTube.
The original file size is ~18MB while the compressed file ended up at 25MB.
While would the compressed file be larger?
Below is the ffmpeg output:
ffmpeg -i HBR_TT747.mp4 -c:v libx264 -preset slow -crf 18 -c:a copy -pix_fmt
yuv420p HBR_TT747_Compressed.mp4
