VideoFileClip opens file with wrong width

[reidoda]

I have a video file that is 426x240, but is opened as 320x240. Is there a way to specify the proper size?

It may be complicated to change the size a posteriori. Could you provide the file ? Or at least run

ffmpeg -i yourfile.mp4

and paste the output here ? So that I can see if the bug can be fixed.

Wow. Thanks for the quick response. The file is here:

https://www.dropbox.com/s/rd84ofj6qoda5fb/test.MP4

And the output of ffmpeg -i test.MP4 is:

Actually, don't spend any time on this just yet. I might know what the problem is.

[Zulko]

Tell me when/if I can close the issue.

[reidoda]

This can be closed. It was caused because I made an error when using ffmpeg change the frame size. Thanks a lot for the responsiveness.

Hi, I'm having the same issue. It appears that @reidoda 's video is an anamorphic widescreen [SAR 4:3 DAR 16:9], where the sample and display aspect ratios are different. I'm am encountering the same issue with my anamorphic widescreen compressed videos and I did not see an option in the VideoFileClip source code to resize according to DAR not SAR. Could you reopen this issue and include automatic resizing to DAR instead of SAR? If not, could you recommend how I work with such data? Thanks!
