here's a cross-media technical problem.

i have a short (2 minutes) film which i put together in the NLE from super 8 original footage. i had the idea that i could make an 'interactive CD-ROM' to distribute it - i.e., friends would be able to view it on their computers as a screen embedded in a full-screen black 'frame', and it would play automatically when you clicked on the icon. (later on, i might get more ambitious).

i saved the movie as a full-resolution quicktime movie out of my NLE. then i downloaded a multimedia authoring programme on free demo from www.ezedia.com.

i had no problem getting what i wanted when i played the master file back from my hard drive. but when i wrote the whole thing to CD-ROM, and played it back from there, while the quality of the video image was great, the playback was jerky and erratic.

(i have dual 1Ghz processors, 500+ RAM, and a 40x read plextor drive, so i think hardware speed is not an issue.)

i assume that the problem lies not in the authoring software, but in the absolute limits on data rate delivery from the CD-R media, which are well below the requirements of full res QT. i assume also that, unless i want to shrink the image on the screen, - which i would like to avoid - the solution to the problem is compression.

so can anyone advise me: 1. am i right in my diagnosis? and 2. if compression is what i want to do, what is the best type of compression to use? i would like to use quicktime, but i'm not absolutely wedded to the format.

TIA:
peter
