Varicam and HD 1080
on Oct 14, 2007 at 11:14:19 pm

Hi,

If I have shot with the Varicam with variable frame rates, say at 8fps and 60fps and I use the AJ-1400 HD VTR to upconvert to 1080...will I lose the variable frame rate flags once it goes through the upconversion on the VTR ?

I only have the Kona 2 so my choice is to work on either 720 or 1080 but I need to figure out how to handle the variable frame rate shots.

I don't think you can maintain the variable frame rate information if you convert, but honestly I have never tried it.

One thing you could do, and this may sound weird, but you could capture at 720p. Run the Frame Rate Converter, then lay the converted shots back to tape at 720p. Then use the deck to convert the shots to 1080 and recapture into the system.

Yep, it's a roundabout way to do this, but actually I did this recently when we had an old project that was 720p and I had created a whole set of graphics in 720p. I laid everything out to tape, and then used the Kona 3 to convert everything to 1080i. It worked really well and I'm sure the deck will convert it just as cleanly.

YES- the neither the software version in FCP or the Panasonic Hardware version supports 1080 VFR conversion

Work 720p. I do this all the time and deliver 1080p masters that look great. Upconverted via the Kona 3.

He has a Kona 2. Cross-Conversion is not an option on that one unfortunately.

What about working everything in 720p and then put the 720p timeline into a 1080 timeline and let FCP6 play it back via the new mixed timeline format feature ?

I suppose I would need the fastest Mac Pro to achieve any reliable playback and even with the fastest Mac Pro, is it reliable to playback a timeline that's about 30mins long ?

I've never tried this and my only concern is you're asking FCP to scale the video up. Up scaling is definitely something that's weak within FCP.
