FAQ: Custom Rendering

Tue Mar 18, 2014 4:01 pm
RE: http://userbase.kde.org/Kdenlive/Manual ... enu/Render

How can I render my cropped video so that:
1/ the output video has the cropped size and not the project size
For instance input is full HD, cropped left and right by 484 pixels, want width to be as 1980 - 2x484
2/ how can I set the preset ultrafast
3/ pass from stereo to mono

With ffmpeg it would be:
Code: Select all
ffmpeg -i inVideo.mp4 -c:a libmp3lame -ac 1 -ar 32000 -aq 0 -c:v libx264 -preset ultrafast -async 1 outVid.mp4


Thanks

Custom render parameters are ffmpeg parameters.
So did you try the parameters you gave in your post ? What happens if you do try this:

-c:a libmp3lame -ac 1 -ar 32000 -aq 0 -c:v libx264 -preset ultrafast -async 1
