Help Me With An Art Project

Hi Everyone,

I've noticed an compelling effect when playing some encoded movies.

An example of the effect can be seen here: http://www.scoopsnoodle.com/bianrec/index.html

Basically, the picture goes all nuts and breaks apart, leaving eery ghosts, beautiful rainbows and confusing scenarios.

I'd like to make more stills like those in the link above, but I've been able to find only few movies that create the effect. I want to be able to encode videos of my own for this purpose.

I'm running os x 10.4. I've noticed this effect most when fast forwarding on the VLC player. I've tried to figure out which codec was used just by viewing the info for a couple files I have. One said MPEG1 Muxed; but the other, which has a more exaggerated version of the effect, is just a wmv with no other info.

While it would certainly be helpful to know how to find out how to determine which codec a file uses and how to encode another file with that codec; the best would be for someone to let me know how to encode a video to display the desired effect in its most explosive state.

As mentioned I'm running os x 10.4, but I also have virtual pc running xp pro.

Thanks in advance for any help.

maybe you should install something like ffdshow for mac

Thanks UncasMS - I got ffmpegX and I'm fooling around with it, trying to find something that works, nothing so far.

The original movie that produced the effect is encoded like so: wmv2, yuv420p, 320x240, 1000.00 fps

Can anyone tell me how to encode like that? Preferably on osx, if not I could use virtual pc.

Thanks

The 1000 FPS is probably the reason you're seeing the weird corruption when Fast Forwarding, the player probably can't handle displaying 2000+ FPS. You can get similar results by trying to view macrovision encoded sources without a decoder.

Hmm... doesn't seem to be the fps, as I've tried 1000, 2000 and 10,000 to no avail. Any other ideas?
