The VideoLAN Forums

Hi all,

The education project that I work for regularly has students some background artwork as a video (say, art.mpeg) and then student action is shot against a blue screen (say, action.mpeg). The method being used to overlay 'action' on 'art' does not involve vlc and is somewhat cumbersome.

This has led me to investigate vlc's possibilities. I see that there are a range of mosaic and bluescreen options, but all the examples I've seen use a vlm conf file.

Is it possible to do this with "one big" command line, rather than a vlm conf?

Thanks,

No.

j-b,

I've seen your replay, and I have more of the same question - I've noticed that while running the windows version of VLC, I can get into the filter parameters from the GUI.
Is that possible to run a bluescreen filter from there (instead of the VLM)?

goes without saying I wasn't able to make it work..

Thanks,

Tal.

In thinking about this some more, I find myself curious about command line options. There are a bunch of "blue screen" command line options. I wonder how they're used, or what they get used for, if chromakey is done through mosaic. I can't find is any examples of where these command line options would be used - I think that would help me understand.

Similarly, there are a bunch of mosaic and mosaic-bridge command line options; some examples of how/when these get used would be rather handy - just for understanding how vlc gets configured.
