Hello There,
I am trying to do a voiceover following this example:
https://github.com/mltframework/mlt/blob/master/demo/mlt_voiceover
For single audio track this works fine, but I am not able find out how to
apply transition for a video containing multi-track audio. Do I have to
separate tracks, apply transition and merge them back together?
I am using following command for single track:
melt -audio-track sales.wav out=499 \
-track v1.ts in=0 out=499 \
-group progressive=1 \
-transition mix start=0 end=0.8 in=0 out=24 a_track=1 b_track=0 \
-transition mix start=0.8 end=0.8 in=25 out=474 a_track=1 b_track=0 \
-transition mix start=0.8 end=0 in=475 out=499 a_track=1 b_track=0 \
-consumer avformat:voiceover.ts \
f=mpegts muxrate=20000000 bufsize=5505024 vb=11000k minrate=11000k
maxrate=11000k \
vcodec=libx264 acodec=aac \
tune=film threads=2 2>&1
Thanks,
Shatrughn
