Error Code I do not Understand

I am trying to stitch some game footage for personal use, but I keep getting this code at roughly 4% and a time scale of over 2 hours. Is there something I can do on my end?

This can be caused by a corrupted video. If you copy the video from the camera to the computer, try to copy it again. What cameras are you using?

They are canon vixias (I know but its what I got.) I think it may be that since it records in 30 minute chunks that then I merge them on iMovie they may not be seamless my frame.

You don’t need to merge videos first. ActionStitch allows you to select multiple videos at once and will treat them as one big continuous video.

will it adjust the order of the videos, for example lets say you have 2 videos for each half which comes out to 4 vides for left and 4 videos for right.

You can only select multiple videos at once for each half. So you first select all videos for the left and then for the right.
