VHS Framerate question...

[RTLdan]

Hello,
I'm trying to convert my VHS home movies to digital.
My question is, when I am capturing, why should I use the 29.97 frame rate rather than film's traditional 23.97?

Wouldn't it make sense to capture the VHS at it's original frame rate? Is 23.97 it's original frame rate anyway?
Thanks,
-Daniel

I don't know what kind of compression you are capturing with, but if you plan to convert to DVD, it has to be 29.97 fps. If the tape's source is film, just use 3:2 pulldown when converting.

Yes ........ and no ...

You have those option's ... closer to actual frame rate of playback is the most recommended ... esspecially as it is nstc format ...

Similar to playing game on pc with video set to clone and recording the play via vcr ... you can record in sp , lp and ep mode's ... and record it back to the pc in the required frame rate without much trouble with pal equipment .

Although I have recorded nstc to pal without any problem's ... just the silly format ... I just add black bar's later to prevent scale issue's ... it work's fine .

NTSC and VHS are 29.97 fps (59.94 fields per second interlace) regardless of what the original source was before it was broadcast.

Film gets telecined before being recorded to tape. You would need to inverse telecine (IVTC) to get back to 23.976 fps.

Same issues apply to 1080i HDTV. 720p HDTV is broadcast at 59.94 frames per second and needs a different process to get back to 23.976 fps.

Your "home movies" on VHS either came originally from a video camcorder, in which case you should LEAVE IT AT 29.97, or they came originally from a film camera (8mm, super8mm, etc), in which case you may have had it telecined with pulldown or you may have had it telecined by speeding up/slowing down. Depends on the transfer house (hopefully they used pulldown).

Since you haven't given us any indication that this is anything other than standard video camcorder footage, leave it alone. It's already at the framerate it should be.
