Up-converting 1080i to 4K in FCP
Hello folks. First time poster. Thanks in advance for reading this post:
I’m running an Intel Mac Pro with:
Mac OSX 10.5.6
2x 3Ghz Quad-Core Xeon
8Gb Ram
AJA Kona3 Card
FCP Studio 2My client has a 1080i 4:2:2 Uncompressed QT file and wants to know if it can be up-converted to “4k” for overhead wall projection (apparently their projector setup can utilize a 4k resolution). Can FCP even do this form of up-conversion and if so, what is the workflow/output settings for a 4K file when exporting from FCP? Does anyone know of some useful software packages/project presets/websites that will help me establish a workflow and address what I am afraid will be numerous stumbling blocks? Have I got this totally wrong and should I be using Cinema Tools thus scraping my FCP idea entirely (LOL)?
Thanks for helping me sort this out.

Thanks for the info. Yes, After Effects I have.
I’m running the Abode Production suite CS3. I suppose this now makes this an After Effects posting
, but what suggestions do you have for taking a Quicktime 1080i and up-converting through AE? -
Hi Christopher,
FC can not manage nothing bigger than 2K.
AE, Shake?

honestly, they might be much better off just feeding the 4k
projector the 1080i signal.a device of that complexity and expense should be able to
scale it equally as well or better than a software upscaling could do. -

Quite honestly your client will gain nothing from this process. The image is not going to look any better just because it’s blown up to 4k.
The only really correct way to do this is to take it to a film lab / telecine house and have them do the transfer in hardware. But again, it’s a waste of time in my opinion, the client gains nothing in the end. They’ll probably get great results just having the projector double or triple the image size if they really want that.

Right on. Good info, everyone.
My fear was that some form of rotten blocking or terrible pixelation would occur in the software conversion process. But what you guys said makes perfect sense. Sounds like they need to examine their hardware and see what can be done to blow up the file on their end as opposed to using a software encoder superfluously.
Thanks for the info, guys. Much appreciated.

The same degradation that when you blow-up a picture 4 times.
The picture can look OK. Applications like Shake have a few filters for upsizing.
But to make this upsizing in software with good quality even with the most powerful Mac would take long, long time.
As Chris and Walter point, probably is better let the projector make de job.

Yes
especially since FCP has a 2K frame size limit.
the only app on the desktop that truly supports a 4K frame size is AE
