Fast trimming is a technique that can speed up the export by remuxing instead of transcoding. But it has some disadvantages.
Only the trim operation is speed up. If the user change the content by cropping, filter, focus, sticker, etc. a normal export is done.
The original format of the audio and video track is retained, if you need a special format, set allowFastTrim to false!
The accuracy of the start time when trimming is deteriorated since the first frame of the cut must be a KeyFrame. The accuracy depends on the source video I frame interval.
The Video preview is stopping while export. This should not be a problem because the remuxing is very fast. Default: false
Set the output bit rate. Default is TAKE_SOURCE_BIT_RATE
Set a specific output size in pixel. Default is TAKE_SOURCE_SIZE
Set the key frame interval in seconds. Default is 2 seconds.
