[FFmpeg-user] Tips for converting MTS to DVD/mp4

[Alex Yelluas]

Hi Marck,

I've been tackling the same problem for the past few days, i have Canon
hfs100 which produces similar MTS files (AVCHD). What I've been doing is
converting them to mp4 using libx264, with
these ffmpeg settings:

ffmpeg -i file.MTS -vcodec libx264 -crf 20 -acodec ac3 -vf "yadif"
output_deinterlaced.mp4

This should cut the original size by about 50%, while still providing
pretty high quality. You can play
with crf value, the smaller the value - the higher the video quality, and 0
is lossless. "yadif" is the de-interlacing filter.

This is still work in progress for me, if you find a better solution,
please share :)

Good luck,

Alex
