  Jittery video when laying off a DVNTSC Quicktime?

  Hi everyone –

  We are having a weird problem that I thought maybe someone could shed some light on. So here goes:

  We created a spot in FCP. We need to deliver this spot to a remote facility via FTP so that they can lay it off, however when we FTP-ed them the high resolution QT of the spot, they reported that the video was “shaky” and “jittery”.

  We are having trouble figuring out why this is the case. Below is a little more information regarding our sequence and media specs:

  The sequence specs are DVNTSC 720X480 / uncompressed. Some of the media was delivered to us as Quicktimes, with the following specs: DV/DVCPRO – NTSC compression, 720X480, 29.97, NTSC-CIRR 601 Lower field dominance. Other media that is used in the same sequence was shot 480i, 24p, 4:3, no letterbox.

  As mentioned, both types of media were used the same sequence (preset DVNTSC, uncompressed), and it plays down fine in FCP. The QT we rendered to be output elsewhere was rendered with the following preset: using Quicktime Conversion, Frame rate: current, DV/DVCPRO-NTSC compression, Quality: best, scan mode: progressive (and, we tried interlaced as well), aspect 4:3.

  We also tried sending different version of this file with animation compression, no compression, etc, and nothing seemed to work.

  When we import the DVNTSC QT back into a new FCP project on our end (simulating what they would be doing on their end for the layoff) it looks fine. However on their end, they are saying it is “jittery”. The “jitters” seem to appear more on the sections of the spot where the QTs were used, rather than the shoot footage. We also went through their sequence settings, etc with them, and they match ours.

  We’ve never come across something like this(?!), and are pulling our hair out trying to figure out what is causing a “jittery” output on their end.

  Any thoughts? Thanks in advance for any insight! We totally appreciate it.
  – Jennifer
