False 2:3 Playback Error

Hey Guys,

Months and Months ago, upon reading some of the manual for print to tape playback, I read that '2:3:2:3' offers a higher quality, I changed my playback settings to try a 2:3 playback. After that I tried printing a few sequences to tape and I got an error "This computer may not be fast enough to playback sequence with a 2:3:2:3 pulldown". (I'm running a single 1.8 G5, but that's not the issue) Anyways, so I changed my playback settings to '2:3:3:2' and every time I print to tape I get the same error "This computer may not be fast enough for a 2:3:2:3 pulldown".

Does this happen to anyone else? Shouldn't a G5 be able to handle playing back a 2:3 pulldown? Wouldn't 2:3:3:2 give you better quality playback as you are able to drop an extra judder frame?

Any info would be ... interesting!

(my computer plays back and I can print to tape using 2:3:3:2 ... but the error keeps popping up ... so everything works fine, I'm just curious.)

Thanks!

2:3:3:2 is not better for viewing. It is fne if you want to archive and then do a advanced pulldown removal on-recapture but 2:3 is best for viewing the video.

It's not just your processor but the whole path of your data, If you're playing off a slow firewire disk to the computer and then to a firewire camera it may not be able to keep up. Make sure you have enough disk space and do what you can to keep the speed running at full rate. (minimize multiple layers, multiple sound tracks, playback off an internal drive, etc)

Scott,

Thanks for the tip, The manual said 2:3:2:3 was better for viewing, so that's what I tried to play it back as.

I'm playing back off of an internal drive, and this same error occurs when I try to play back even the smallest sequences. (1 or 2 tracks, straight edits)

Do you know why 2:3, is better for playback than 2:3:3:2?
 
Re: False 2:3 Playback Error

To change 24fps to 30fps you need to add more fields and stretch it out.
2:3:3:2 does so by creating a new full frame every 5th frame.
2:3 uses fields to spread somes frames over 1 1/2 frames. By using fields the original frames are spread over more evenly in time so the playback appears smoother.
