The VideoLAN Forums

Hi, I made the mistake of doing a screen capture to Uncompressed AVI files and many are over 2GB in size. VLC seems to be the only thing that can play these things beyond one minute 16 seconds. Unfortunately, I need to do some subtle color changes and compressing these to H264 kind of ruins that. (not to mention the .mp4s output by VLC 2.0.0 turn green and get distorted in After Effects and Premiere so I can't edit them anyway)

In the Wiki, I see instructions for saving a stream as a .png sequence. However, I don't know how to get it to work given the examples.

http://wiki.videolan.org/Video_Output

There are a couple examples on the page
One shows how to get asci art output "vlc my.avi -V caca"
Another shows how to save png files from a webcam "vlc v4l:// --image-out-prefix=webcam --image-out-ratio=20"

I tried several variations on this including:
vlc my.avi --image-out-prefix=test009
vlc my.avi -V image

Some times I get a progress bar but no files saved (at least I can't find them), other times I get and error message saying the options cannot be parsed.

Can someone please tell me what I need to do to transcode an avi file to a png sequence?

Thank you.

The image video output does not exist anymore. There is a scene filter nowadays. But that's for making snapshots regularly while playing back, not for transcoding the whole video to images.

Could something like it be reinstated? To get a good still of a scene, one has to use several frames, run them all through a image processor, and then see which is acceptable. Doing the frame/snapshot sequence many times makes this quite undesirable. I have gone to another video player which does have this ability as a result.

The idea might be to have a key toggle setup that would start and then stop taking frame snapshots.

The image vout was not a correct solution to your problem either. So I don't see what's there to be reinstated. In any case, the old code would not work within the current VLC.

In other words, until someone cares to write the code, nothing will happen.

Until someone writes the code nothing ever happens.

This is a feature request.
