Downconverting Variable Speed 720p24N footage to SD
Have done an hours worth of searching on the board, so please don’t shoot me if it is here and I haven’t found it.
Just got back from London where I shot my first footage with HVX for a video for a corporate client. The HVX was very much my B-Cam, and our A-Cam was the SDX-900.
To get speed effects, I shot in 720P24N. I shot primarily in 12 & 60 fps. Looks great, very cool when played back in camera.
Now I’m back in the states. My editor is working with my SDX-900 footage, and I’m doing my best to downres the 720P footage so I can lay it off to a Digi-Beta tape.
I’m using FCP 5.04 and AJA IO.
Basically asking for what the best recipe is for downconverting this footage to UNCOMPRESSED 10BIT so I can lay to tape and pass to my editor.
I have tried a few methods, and this is the one that has worked so far.
A) Import footage from P2 cards
B) Batch Export footage with UNCOMPRESSED 10 BIT sitting
C) Re-import these clips and place them in a UNCOMPRESSED 10 BIT sequence (the Easy Setting preset)This works, but to my eye, I’m seeing some strange strobing and stair stepping in the footage, plus, when I re-import the clips, I get the scary FCP warning “These clips not optimized for Final Cut Pro.” That said, when I place these clips in a UNCOMPRESSED 10 Bit sitting, they don’t require any rendering.
As anyone found a way to down convert this footage successfully, with the proper pull down, within FCP?
Thanks for input.

Honestly, you should layoff the sequence to tape (digibeta would be best, but DV50 might work since you probably have that gear), but you need an AJA Kona 2 to do the real time downconvert. Then have your editor recapture from tape.
You could also bring it in to a 23.98 After Effects project, scale it down and add the pulldown in the output module.

Thanks for the quick response.
Yes, I’m sure that the Kona 2 would provide a better end result, and I’m sure the AFter Effects method you mentioned would work as well.
I guess I’m still wondering what the best method for transcoding/ downconverting in FCP would be. It is capable of DOING a downconversion, but I’m just curious what the BEST method within FCP would be.

You could use the advanced format conversion tools in compressor. Compressor comes with FCP.
Your results may vary.

Isn’t there some way of doing this in the camera? or is it only to the DV tape drive? That wouldn’t be very helpful… but can you out put the down convert through the firewire to a DV50 deck?
