DV to SD10bit interlace problems
Hi All,
Thorny one for you. I’ve started with DV PAL material, cut the piece, added GFX and CC’d, and placed completed sequence in to an uncompressed 10-bit SD timeline for final render and output to DVDSP via Compressor. Everything looks lovely… exept for a few slomos (all 50%) at the head of the programme. They look like the field order is wrong, with that tell-tale staccato motion.
I’ve tried everything. FCP has, as I would expect, placed a shift fields filter on all clips on going from DV (lower first) to 10-bit SD (upper first) and there are no issues anywhere else…
Now this is compounded by me not having (at the moment) any way of monitoring to my venerable JVC broadcast monitor – a situation that will change soon – but till then I’ve had to resort to trial and error, making a sequence of the offending clips repeated and trying all possibilities.
Change field order from -1 to none
Change field order from -1 to +1
Remove shift fields filter
add frame blending on the time remap filterNone seems to have any effect. Am I missing something??
Yours frustratedly,
Jason

Hi Jason,
i have had this problem too. I find the FCP slowmo bad at the best of times anyway.Have you tried deinterlacing too (using stibs free version, try all the settings).
What i have found working for me is the following:
-finish and grade the slowmo sections, but in a DV sequence, without shift fields and deinterlace filters
-export each one as a dv quicktime
-then import and place in 10-bit timeline, adding shift fields (will be added automatically)
-add dinterlacing if you have elsewhere in the filmThis makes the slomo smoth for me
cheers

David,
I’m well aware that DV is lower and any other SD is upper… and that’s why FCP sticks the shift fields filter on all the clips. I was wondering if the act of rendering the slomo in the SD sequence made the field order funky, but as I stated I’ve tried most every combo I can think of regarding field order and it still happens.
I’ll give your suggestion of recreating the slomo in the SD sequence a try and report back, will be interesting to see if it has any effect…
Jason

Hi,
Are you by any chance working with FC 5.1.x?
I had the same problem for few months while I had FC 5.1.2. I realized was not an interlacing issue. Was just that (I don’t know why) FC couldn’t make a proper slow-mo. With FCS2 the problem is gonne.

Rafael,
Unfortunately (or fortunately, depending on your poiint of view) I’m on FCS2, with all updates , the latest Tiger and QT.
So that’s not it… ahh well, I’lll keep trying. The sooner I get my Multibridge installed the better.

Hi guys,
yeah unfortunately i’m still on FCp 5.1.4, and i’ve never been happy wit FCp slomo. Will think about the upgrade if you think FCP6 is better.But in therms of jasons problem, i defintely suggest exporting a dv version, lower field first, then importing that into the 10bit sequence (thereby adding the shift field filter after the slomo has been done. Its the dual change of uprezzing/field shiting and slomo that creates the crappy shuddering motion.
