- Yes, you can "stretch" the picture resolution by simulating the pixels
- between which are missing with algorithms.

- Correct. VHS is a bad alternative. It has the lowest signal resolution (H275)
- available. If you are gonna use 1500x1500 I'll asume you are gonna use it for
- analog film which has a line resolution of 1200. You should use atleast a
- component signal for the job. I did a project with analog film and we had to
- scan each frame with a scanner to get approriate quality. A frame grabber is
- not good enough for this if you require professional quality. It's no point
- using 1500x1500 to other things than film or DTP.
- (sorry, using 'you' in general).
