I grabbed a short clip of footage out of my movie project in iMovie, and saved it to a .png file, then transferred that to my PC and tried to load it as a background in PIllusion.
I got an error message to the effect that the format is not recognised by PI.....!
So, I went and got the same clip, saved it as an .avi, and loaded it as background. But the picture was ghastly! Totally pixellated and it almost looked like a 32X32 jpg that had been enlarged to 256X256!
Not only that, but when I hit play in PI, every several frames, the footage seemed to pixelate even worse, until it ended.
I can't find anything in the manual to address the best way convert existing camera footage so that it looks good in PI. My attempt to convert it to a .png sequence obviously went wrong somewhere.
Theo, I have to admit I'm a moron when it comes to things like codecs etc.. Got a vague idea of what they're used for, but I'm not familiar with the various differences between them.
That said, I've since read another post here where someone was having a similar problem, and the Lagarith codec was recommended. So, I've downloaded it and will install it in the computer and see what happens.
And I just now found a site that explains all about them for dummies like me. Apparently, the codec one uses makes all the difference, (as you no doubt were going to say!) :)
Thanks for your response. Let me try the Lagarith and I'll see if it fixes the problem.
