Export does not start from the start of the video #54

This problem happens pretty often when analyzing longer videos (50-100+ gb). For example, if the video is 29 minutes long, it will export the images from the 4th minute. When I merge the images, I can see that the video is 26 minutes long instead of 29 minutes as expected.

It does not happen with smaller videos, it seems.

Hm, interesting. I'm kind of dependent on OpenCV to iterate through the frames. I'll check it out when I find the time. Have you checked it with different kinds of videos by any chance? Could you also please share any meta-data such as the recording device and its settings for the raw video?

So I checked how I export the image sequence and I didn't see anything obvious. Have you checked that you import the image sequence with the correct frametime (the same as it was recorded)?
