The VideoLAN Forums

Hello, I have a movie (*.MOV from a Canon 550D) recorded with 50 frames/sec and I would like to extract all of the frames in order to do some calculations later on.
The problem I have is that about half of the frames are missing when I use scene-ratio=1. From what I can understand from the forum, this has something to do with the architecture of the current VLC version (1.1.11)?. If I add --rate=0.5 to the command line, it seems like I get about the right number of frames when I extract them, but I don't know if I get the correct frames. Is this the right way to solve the problem for me?

I have also tested the image-out method which extract all the frames with an older version of VLC (0.9.9), but when I use that, I get very poor quality on the images, so I can't use them.

I would appreciate if someone could tell me if my first solution, enter --rate=0.5, is correct, or how I could change the preferences in the older version of VLC so that image-out produce images with as high quality as the images from video-filter=scene in VLC 1.1.11. Becuase I will have a small presentation about the results tomorow morning

Thanks in advance

May have been a little too late but have you taken a look at this article for frame grabbing at:
