Pan and Scan from 2K (2:40) to HD (1:78)

Hello to all,

We're thinking of doing a pan and scan version of a theatrical movie in-house and were considering using FCP equiped with a Kona LHe to do it.

The digital master will probably be an anamorphic 2K DPX sequence, for which we will render a ProRes proxy. For each reel of the film, we will drop this proxy into a 1080 timeline and notch the clip using an EDL to facilitate the pan & scan. Of course, the proxy will be resized inside the 1080 timeline so that it fills the frame vertically, leaving only the panning work to be done, shot by shot. Once panned, we'll reconnect to the master (via Automatic Duck and After Effects) and render the 1:78 HD version to an image sequence.

The question is the following. Using the Kona LHe, will the 1080 timeline containing the 2K ProRes proxy play back in realtime while we're working on the pan & scan? We'd hate to tackle a job were every shot of a 2-hour movie needs to be rendered to check the work. I know that the Kona LHe does NOT play 2K out to 1080 (only the Kona 3 does that), but will it play 2K nested in a 1080?

Tests have been planned, of course, but I'm looking for a quick opinion before we decide to tackle the job.

The machine is a 2x2.8Ghz Quad-Core Xeon Mac Pro with 10GB of RAM.

Thanks,

A nested 2k mov in ProRes Proxy (or is that a proxy that's ProRes) in 1080 should be easy enough to playback, yes. It will need to render at some point, for exports et al, but you know that.

Have a decent raid?

Hi Jeremy,

It probably will be a clip in ProRes Proxy format, come to think of it. It has nice enough quality to judge framing and super low bandwidth. That said, we have a RAID that spits out 550 Mb/s sustained, so any ProRes format will probably work.

And we're not rendering anything out of FCP. AutoDuck to AE for the conform and render.

Thanks for your help,

Sacha

Mbs or MBs? Huge difference. Either way it will handle ProRes Proxy.

Typo. MB/s. Megabytes. ;)

Best,
