Just read your posts. I’ll have a look. The animation ON THE EXPORTED VIDEO should only last as long as the clip is. So if the clip is 10 seconds long it should only be 10 seconds long on the exported video.
It will vary when you look at the clip IN REALTIME depending on how much work Shotcut has to do to show the frames.
Can I double-check that the video you posted above was the exported video file and not a video capture of the Shotcut application with the setting “Realtime (frame dropping)” unset?
The uploading worked by the way, so I can have a look at it on my Surface Pro after dinner tonight.
Regarding the query about a time of 0.1, this equates to 10% (0.1) of the length of the clip to which the filter is applied. So for a 10 second clip it means 1 second, for a 60 second clip it equates to 6 seconds.
