generating video from image sequence drops frames at end

Check that there is no single gap in the sequence, and no format change in the numerical part of the names.

Try to be more specific on your bug description:
    - describe how you renamed and renumbered
    - tell which frames were imported, and which ones were not
    - repeat your above experience with several sequences of different lengths to see if there is a pattern

I know this thread is old, but I came here when looking for a solution.

I had this problem of OpenShot dropping frames at the end of image sequences. The sequence in question was named 000.png, 001.png and so on, with no gaps in naming. All frames were imported, but didn't show when exporting video.

The problem was that the project was set to 30 FPS and then I was exporting to 25 FPS, which was the fps value I wanted. By creating a new project, setting it to 25 FPS, importing again the image sequence, and exporting the video to 25 FPS, the complete image sequence was correctly exported.

Perhaps a warning about exporting to a FPS setting different than the project could help with this.

FPS: Frames Per Second

Been 2 years since last post on this. I just experienced the same problem, making a video out of an image sequence and it was truncating part of the video. Odd thing is you can see the full video in the preview but it truncates it when you export it. Version OpenShot 1.4.3

Alejandro's suggestion above resolved the issue for me (thanks).

Exporting only gives 29.97 FPS as an option -- not 30 FPS. When I tried exporting with 29.97 FPS I still had a trucation.

I'm having the same problem with OpenShot 2.4.1.
