Hi Chris,<br><br>Thanks for the answer. I guess I'm stuck with playing back about 16 movies<br>at once then... at least per machine.<br><br>I recall using an array of pix_multiimage objects, and I think it did not<br>reload the same images over and over again but somehow managed to access

That's a very, very different object. pix_film/movie use QT API calls which cannot be used in the same manner.<br>

Do you mean you are dividing 1024x768 into smaller clips and tiling
across the screen? A single 1024x768 is probably going to play
better than 4 512x384 clips. Also, use pix_movie if you don't
need to do any pix_ processing on the video for better performance.<br>

The limit per process in a 32bit OS is 4GB.<br>

You could decompress the movie into a pix_buffer if you have enough RAM. 720x480 is just about 1GB per minute as I recall.<br>

<br>version of QT will be useful for playing many clips simultaneously.</blockquote><div><br>
I could not reproduce the problem here so I didn't send it.<br>
