- The easiest way to do it is to re-shoot the tape with a PAL video
- camera!
-
- But, if you insist, I think it is possible to use a computer to digitize
- each frame of the NTSC tape and to record each digitized frame on a
- PAL format video.
-
- This, of course, means that you must have an NTSC format video which
- can display the NTSC tape CLEARLY one frame at a time (so that it can be
- digitized by your computer), and you must have a PAL format video which
- can record one frame at a time. In other words, we're talking big
- bucks invested in equipment!
-
- Good luck!
