1080/24 HDV in a 720P/24 DVCProHD timeline??

I'm working on some promos - which always means I'm dealing with different formats.
I was given some Quicktime files that are 1080 HDV files at 23.98fps.
I'm working in a DVCProHD 720P 23.98fps timeline.

Every which way that I've tried to convert this video it comes out jumpy.
Not sure what I'm doing - but I've tried everything from dropping it directly into FCP and rendering, to exporting the HDV file out of compressor as an Animation codec file, Uncompressed file, and a few others BEFORE compressing it to DVCProHD.

Nothing I've done so far helps.
The HDV file itself plays smoothly in Quicktime - so I know its not the source material.
But as soon as I render it to DVCProHD, it gets very jumpy (as though it's skipping frames).

I know 'jumpy' isn't the most descriptive term... but...any thoughts?
 
The only thing I can think of is the sequence settings, look at the source info of your footage closely and try best to match it up in the sequence settings.

Which version of FCP?
 
FCP 6.0

The sequence I'm working in has to stay as DVCProHD 720P 23.98

I'm cutting this stuff into an existing promo - and the HDV video is just one clip of many that I have to drop in - and it's the only non DVCProHD clip I'm working with.

I could take it into another sequence I suppose - but at some point its going to have to find its way into a DVCProHD 720P 23.98 sequence.... hopefully.
 
Okay, now I'm totally puzzled - I tried to render out just a 1 second sample clip so that hopefully someone would see what was happening and be able to give me an answer -

So I rendered out 1 second at DVCProHD 720p 24, and of course it was jumpy.
Then I rendered out a 1 second sample in the native HDV codec of the file - and it also came out jumpy.

So - a side by side comparison won't do me much good unless I can upload the full HDV clip (which is 60MB). Not going to bother with that.

So... anyone out there working with HDV and DVCProHD together?
 
Well it kinda depends- are you sure it's really 24p HDV at 1080. Not too many cameras shooting that right off the bat- which camera did it come from?

I'm not certain what camera it came from - I can find out possibly.
(the clip came from the company who had it produced - not from the source).

Looking at it in QT the 'movie info' tells me:

Apple HDV 1080p24, 1440 x 1080
 
Can you cross-convert into Apple ProRes 422 using Compressor? I think I recently received some underwater footage that was shot HDV and converted to Pro Res and it cut perfectly into a DVCPRO HD 720p 23.98 sequence.
 
Yup- I'd make sure it was actually pulled down properly in the first place. Not too many cameras shooting 1080/24p. Might have been improperly captured or pulled down at the source.

Well, I'm not sure how to tell if it was improperly captured or pulled down at the source - the HDV file plays perfectly fine in both QT and FCP.

I pulled it into Compressor and exported about 5 different files - HDV, ProRes, AIC, Apple Uncompressed, and DVCProHD - all came out jumpy.

I appreciate the attempts at help on this - I know its close to impossible without seeing the files themselves or having more information.

As of now I'm just going to find a way around using this clip until I can get an alternative from the client or more information on what exactly I'm dealing with here. I've got more than enough other work on this to keep me busy in the meantime.

Thanks guys.
 
I've moved on ... (using alternate footage now)

But for what its worth, I just got word from the producers of this clip that is was shot, "with a Canon HV 20 (1080p setting at 24fps)"

Figured I'd follow up here with that info, just for good measure.
