Render times for resizing SD to HD… how long for a one hour show?
I’m weighing the options of doing an upconvert of a SD show to an HD master on my FCP system. Sure, I can take it to my friendly Post house and using their Terranex or Alchemist get it done in real time. But, that would be too easy! I’m trying to keep it under our own roof, so I’m exploring some other workflows. I’ve read about Red Giant’s “Instant HD” and Digital Anarchy’s “Resizer 2.0”. Both seem aimed an the occasional clip and not an entire hour show. Am I nuts? Will the render times be measured in days, not hours?
I’d like to hear from anyone who’s had experience with these plugins or any other method of accomplishing this (Within FCP).
Thanks.

Well thats hard to say in the abstract… since that will all depend on your system, how far you’re resizing things… for example if you use a quad core its going to be much faster then a dual core… but on the other hand if you only have 512mb of ram well its going to be really slow… So if you can give some system details, and SD res that you’re working with and the HD res you want to shift too…
That would help…

You can put the SD sequence as a nest in an HD sequence and render. I have never done a whole program, but short sequences. Much much slower than real time. I think the Teranex option is quicker and probably looks better.

Simon,
Here’s the specs.
Dual core 2.5 CPU. At least 4 gigs of RAM.
Original size is DVCPRO 50 SD shot anamorphic squeezed (16 x 9 expandable). Intent is to blow up only to fill a 720p frame. We do have multiple systems, so I’m contemplating breaking the show into segments to render simultaneously.

Michael,
The more I research this the more I think you may be correct. Anybody out there have experience with the Teranex “Mini”?

The other option if you have a Decklink HD pro card is to uprez on the edit to tape. The Decklink can up and down convert SD- HD. I use it to down convert from HD to SD digi beta.
My clients agree it looks as good if not better than a software down convert (particularly 4:3 LB) and it is real time. Not sure if the up convert is as useful tho.

Check out the posts on this forum, it looks like some people are looking at a workflow issues with Teranex….

Mark,
I was playing around with Resizer and Instant HD and as I recall a :30 clip was going to take hours. Your show could take days.
Try chroma sharpen from the Natress filter set. Much faster.
Have a wonderful day.

with both products you can download a demo. fully functional but puts big ol x across the image.
each app, Instant HD and resizor 2.0, have “levels” of quality. and i think resizer comes with de interlacer as well
but even at medium quality, it is not fast, nor even moderately fast (resizer even sez in the manual that you should really think about wheter or not you need the High Quality settings, as you may be unsatisfied with the render times)
I would suggest downloading the demos and trying em out!
hope this helps
