re: URGENT- Strobing on NTSC DV DVD from 1080i source?
Hi,
Project needs to go out today on DVD to the client but, while it looks fine in computer DVD players, I’ve got serious strobing throughout the DVD when viewed on TVs. (Been testing on a plasma/LCD since that’s how the client will display it.) The project is mostly 1080i source (29.97, upper field dominant) and that’s the stuff that strobes like a mofo on TVs.
Here’s how I got here:
Edited in 1080i timeline in FCP. When finished cutting I copied and pasted the 1080i sequence onto another 1080i timeline, nested it and copied that nest to a DV NTSC 29.97 timeline– then went out through Compressor using the 2-pass (90 min, best quality, 4:3) and everything that was initially 1080i is now totally strobed. Anything that was 720pa initially is totally fine. It’s not an issue of image effect filters on my footage, I tested and know that for sure. My suspicion is that it’s a field dominance thing.
If anyone can offer fast advice I’d be incredibly grateful. I just put a -1 Shift Fields filter on some of the footage and am rendering out a chunk to see if that’ll fix it. I only have access to Macs (FCP and DVDSP) so please if you’re able to offer advice it would be great to focus it to the resources I have available.
THANKS IN ADVANCE!!! Need to get these working and FedEx-ed ASAP.

Thanks, Dave, much obliged!
What you recommended was exactly what I was doing when I posted. I’d shifted the field order to lower first on a bunch of stuff, compressed, and burned a DVD. Presto, it worked. (By the way all the 1080i stuff is, as far as I can tell, natively upper field first, hence the problem copying it into a DV timeline. Makes me very curious about this format-independent timeline promise…)
Wasn’t aware that dragging a ref quicktime from FCP to Compressor would save time. About to try that.
And yes, it’s super frustrating figuring things out against a ticking clock– so I REALLY appreciate your help!
