1. If you can shoot 24Fps, then do it, but a lot of cameras only do 18fps...
2. You can get a true telecine done at several location (my personal recommendation, used several times, and the best price by far -
www.thetransferstation.com ask for DOUG). It's expensive, but worth every penny. $150 an hour, but it's a true Rank transfer at the highest possible resolutions & quality.
3. I use Mini DV and Dat to synch audio, but it will drift unless you have a crystal synch camera (very rare in Super 8). I advise shorter takes...
4. no idea
5. There are a lot of FCLIKER's in the U.S> and abroad.
