I have read a lot from this subject I have got to the next conclusions:
- There are people that says that the resolution of VHS tape is 352x288, but this is not exactly cause de VHS have two fields interlaced. So you must capture at 576 vertical resolution to get both fields.
- And a lot of people claims that there are extra information beyond 352 horizontal resolution, so it might be wise to capture at higher resolution (better safe than sorry: so it would be 768), and then resize to final output.
- The VHS tapes (almost the ones not recorded from TV) have junk at the bottom of the image, at 576 vertical resolution they are approximately 15 pixels, so you have to crop them. 576 - 15 = 560
Then we hace 768x560, now is time to do the resizing...
But there comes another problem, the bigger the size, the bigger will be the blocks of xvid cause of it will have more data to process to fit same the file size (2 hour in 2 cds)
I think 352x480 looks like an acceptable resolution (CVD resolution) but the problem is that the player must support resizing for playing it correctly.
Opinions are welcome
