motion judder in FCP5 output to compressor/dvdsp

[Sean1976]

Hi all,

I'm having a weird problem with output to compressor. In FCP all of my pans and camera movements look fine, like they did when I shot them.. but now I'm having this problem with "stepping" or "judder" when I look at those shots in my m2v file or when I burn a dvd. However outputing a 24p quicktime looks fine too. I shot on a dvx 100a (24pa) and edited at 23.98. just to trouble shoot in case I accidently shot in regular 24p (unlikely). I dropped my final edit into a 29.97 timeline and output to compressor with that and still had the problem...

Help I need to make a dvd!!!! anybody know how to get this juddery motion to scram?

ps it's doesn't happen with "action" in the shot, just with camera movements.

thanks!

Ey Sean, it really does sound like it is a pulldown issue not a compressor issue. Unless you compressed it quite a bit it shouldn't step or judder although anything is possible really... That is the nature of 24p when viewed on a ntsc monitor or TV set when pulldown isn't removed. Camera movement will cause this too and often when viewing it in FCP or Quicktime on an lcd or "progressive" monitor it may not be as noticable. There are two ways to look at it, either your burning a "true" 24pfs dvd which you export to your dvd authoring program, or you add the pulldown to a 24p sequence in your realtime playback settings. If you've done either correctly and you still have this problem it is because of two much camera movement. Be sure to double check your export settings in FCP and Quicktime before you encode and always view it on a NTSC monitor before you do.

thanks for the reply. the wierd thig is that I don't have the option to add the pulldown in the realtime playback settings. just "full quality" and "use playback settings."

strange..

any ideas?

The "full quality" playback setting adds the pulldown to a sequence however this is primarily used when printing back to video tape. If you added a 24p m2v or 24pa quicktime file to a 29.97 sequence you will still need to remove the pulldown since this is how fcp and it's 2:3:3:2 pulldown cadence works (someone please corect me here i could be waaay off). If you did make a 24p dvd and are still having the issue then i regret to inform you that it may definately be from too much camera movement and there isn't a whole lot you can do besides re-shoot.

It's not the camera movement. My pans are very very slow and very very even moving. I'm going to reimport with different settings and see what happens.

I've never tried this but is there anyway I can export my EDL from my current cut and use that for when I reimport the footage under different capture settings?

Never done anything with EDLs so I have no idea.

thanks!
