PAL to NTSC

Hi guys,
I have footage in PAL 25p and need to send it over to the US in NTSC. Whats the procedure? Would resizing the res be enough or would an NTSC be expecting 30 FPS also? BTW I am a Premiere Matrox guy.
 
If you're trying to make it playable/usable over here, you'll have to convert it to NTSC-compliant video. Which means probably slowing it down 4%, converting 25p to 24p, resizing the frame to 720x480, and rendering out to a DV NTSC file...
 
I jumped through this hoop with a big project just recently. I did a lot of experimenting and without resource to really expensive transcode hardware I found the best results were obtained from Canopus Procoder 2.

Atlantis was awful at this job - results really soft, but you can try their download yourself.

TMPGEnc Express 3 is really good, in fact it gave the best results if transcoding to 29.97fps, though still very jerky on camera pans because of the frame interpolation. Procoder was bad going to 29.97 as it interlpolates missing frames by mixing going to 29.97 from 25p and this gives the impression of phasing in and out of focus every second on camera moves.

However, you really want to be going to a framerate of 23.97. ie. go from 25p to 24p. This eliminates the need for frame interpolation and while there is some 'jumpiness' from frame removal, it is by far the easiest to watch. Procoder wins here but don't dismiss TMPEGEnc as it is way cheaper.

Another tip: use a frameserver rather than go through the process of making a render file to work with. Check out the Debugmode site http://www.debugmode.com/frameserver/

hope this helps

Tx michael, will try it out, tx pookie . . . barry are you saying that 24p ntsc would be acceptable as a format for regular editing houses there.
 
Theos - sorry didn't understand that you were sending the footage rather than a project. In this case I would ask the edit house if they can do the transcode from master or master copy tapes themselves - they've probably got access to far better facilities than using software solutions.
