Is it possible cutting a long video uploading a list of time (start and end time of each clip) in Hitfilm Express?
Unfortunately I think what you are asking for is beyond Hitfilm Express or Pro's ability. It sounds like you want to run a script that will cut your video based on a list of start and finish times on a video. Unfortunately Hitfilm currently can't do this. You would have to do this manually.
Sorry I thought I found a solution but upon installing it was from 2013 and just didn't work.
