No you can’t trim multiple clips or batch cut and paste etc. Sadly automation options are not yet a feature of LumaFusion which is a pity since most users on this forum seem to use dozens of clips.
At least with photos you could perhaps have set the default photo length to 4 secs and then started the project again.
Thanks for the reply Mark. Saves me looking for something I assumed would be in there.
Hmmm... time to head over to the wish list thread and put my dibs in for such a feature. Seems it would put this app way out in front of the competition.
