Make sure you’re setting the timestamps correctly, and make sure to open the .funscript file instead of the mp4 file. Make sure to hit Save before you process it.
Also I think only the 2nd and 3rd checkboxes work now.
Curious on how you got the error.
I tested out from what @Midevil was using, and I made some additional bugfixes.
1 - changed to ffmpeg from moviepy when combining non-same files - timing is more consistent when appending clips this way. Also encodes the video to the largest video size out of all the files.
2 - fixed some more timestamp handling with getting the perfect timings when making clips - accounted for clips that start at 00:00:00.000 or end at the length of the video.
Sorry for not keeping up with this as much as I’d like to but I’ve now edited the main post and github to reflect these changes.
Tried out the program and it works really well! I would love a feature to enter multiple time frames for a single video/script and then combine them. I think a lot of users would appreciate this feature as you would be able to cut out sections you don’t like to save some disk space (especially for huge vr videos). Great work so far!
Edit: Basically like the app lossless-cut, but with the amazing script cutting functionality of this app.
You can do that with this you just have to select the same script/video each time you browse.
I missed that, thanks a lot!
Complete novice here. Where is the download ? What do i do to install ?
Read the first post.
It’s a python script so you need to install python first and run the commands as described in the hidden section “How to run the Python Script”. As usually with python scripts there are a lot of manual steps to go through to set up the environment.
I’ll pass then, too convoluted and complicated for me, thanks anyway 
Just got this installed and working. Took a bit to get python to work with the help of Gemini.
Is it possible to combine clips together without going through the cut process? To combine together short clips for example. It looks like the program is cutting out and saving the clips and scripts, and then combining the clips and scripts. Is it possible to skip the first step?
I tried out to create a compilation video but my funscripts are not in sync with my videos after cutting them with the app. Same thing when combining the videos and scripts directly, it doesnt fit anymore. They seem to be off a few milliseconds.
