Compression software for iMac DV Can't Post
Can anyone tell me a good compression software for digital video? What do I have to do to store my digital video onto CD's using a Spressa FireWire CD-RW?
Thanks,

Doesn't iMovie already have some preset file formats for compressing video to upload to the web?
If you want to store videos that only will be seen on your computer screen, the QuickTime 4 Pro upgrade will be a good choice. ($30) Use sorenson or H.263 for video, and Q-Design Music for audio.
If you want to store video to be used in other video projects and put on TV, don't recompress the files. Just save them on the CD in the format that they imported as. Such files probably won't play smoothly off of a CD, but when you copy them back to your hard drive, they will be fine.

Allen,
The one video I downloaded into my iMac used 2.5G. How can I put that on a CD to view on my T.V.?
I suppose I could always mirror onto my T.V.
Thanks,

Ambiguous question [In reply to] Can't Post
I still don't understand EXACTLY what you are trying to do:
1) Are you trying to burn a Video-CD that will play in stand-alone DVD players? (I don't know the details of how to do this.)
2) Are you just trying to save space on your hard drive by copying old footage on to a CD? (You can't play DV footage off of a CD in real time - CDs are too slow. You'll also have to break the file into 4 parts. It would make more sense to copy the file back on to a DV tape.)
3) "I suppose I could always mirror onto my T.V." (iMacs can't do this without special add-ons. Tell me what gear you are using. A USB based adaptor won't be able to give you smooth movement.)
4) Are you just trying to make the file smaller? (If your iMac has some add-on that lets you mirror video on to TV, and you don't care about going back to a DV camera, then use QuickTime 4 pro as described before. You can get close to TV quality like this, (240x320/30fps) and the file will be much smaller.)
