Works for some videos but for some videos it gives this error

Thanks for reporting the issue.

If possible, can you provide some more information for me to reproduce the error:

bipindr123 commented 5 years ago

Hi command used: python3 -m vidstab --input input_video.mov --output stable_video.avi I tried it on a bunch of videos I had, of which only 1 worked. I also tried it on a youtube video downloaded and it didnt seem to work. Also i tried converting the video to different formats and resolutions but to no avail. I am uploading one of the videos it failed on. https://drive.google.com/open?id=1TfexTs1XTY_un0YMfe67xU390IWGOGve

Thanks for providing the additional info.

What version of Python & vidstab are you running? I couldn't reproduce the error on my local machine (Mac) using Python 3.6.5, vidstab 1.6.0, and the video you linked.

bipindr123 commented 5 years ago

Hey I tried it again and it was a stupid error on my part of not being in the correct directory. (although it somehow worked one video) my bad, very sorry for wasting your time thank you for your time

Happy to help debug. Glad you figured it out.

This should be a more descriptive error message though. I've opened up #71 to avoid this confusing error message in the future.
