DI color grading and back to FCP

So I'm in the midst of color correction on a feature shot in 720p24N with the HVX. We're doing the correction on "Scratch" at a buddy of mine's FX house. He's doing it as a favor, but I think we may have screwed up our process. Some help would be great.

His system wanted to work in DPX or Cineon files, so we outputted a TIFF image sequence from FCP and gave it to him. The TIFFs were converted to DPXs and that's the image sequences we've been doing our color grading on in Scratch.

Now I need to burn some screeners for some festivals. He can't output a DVCproHD quicktime from Scratch, but he can output a TIFF sequence. Can I just have him output a Tiff sequence and then I put that Tiff sequence back in FCP and it should work fine and I can encode and mpeg-2 from FCP with compressor? What sequence settings should I use? Did we lose anything going from DVCproHD to a TIFF sequence in the first place? Should we have not done that?

Any help would be great.

Thanks,
Brian
 
TIFF is uncompressed (or at least can be...), so quality shouldn´t have suffered...
Some claim that converting a compressed video format like DVCproHD to an uncompressed one like TFF or TGA before CC will improve results...
Just import the TIFF sequenze back into FCP, sync the sound and export the DVD.
 
Thanks.

A couple last questions. When I ask the post house for a TIFF sequence should I tell them to give it to me as 960x720 or should I say the 1248x702. I never seem to know when I'm in square or when I'm in HD pixel aspect ratio. And do I need to tell them about a timebase?

Then when I get the TIFF sequence. In final cut I just make a sequence that is 960x720 with the HD pixel aspect ratio. With a timebase of 23.98. and Then under "Quicktime Video Settings" should I set the compressor to TIFF?

I just want to make sure I'm asking for the right thing and I'm getting something that I can correctly put into FCP and have the image be right and the sound sync up.

Thanks again,
Brian

You actually might have better results assembling the sequence in something like after effects. It is designed to handle image sequences much better.
