Re-render on output
Hi all!
I am doing finishing on a 45 minute show in uncompressed 8 bit pal format (decklink). I am using FCP 5.1.2, QT 7.1.3, Black Magic 5.7.1 drivers in a G5 dual 2Ghz with 4.5 Gb of ram.
Now, what I do is that I get a DV project which I use media manager to re-compress to 8 bit uncompressed, duplicating everything and creating a new project.
As there are a lot of graphics and stuff that are non-interlaced I nest all the DV video and work with my nested sequences to do all the CC and field shifting etc. Then on the nested sequence I add a couple of filters (nattress G Film and vignette) for the final look.
I then render everything over night (it takes something like 8 hours or so). So, the next day when I show up and want to edit to tape FCP starts to write video, something that takes 20 minutes. No big deal, but when I want to do another copy it does the same thing again. And in case I missed something in the show, I got another 20 minutes to drink coffee.
Is this something that is supposed to happen? I mean, if all the sequences, even the nested ones, are renderd, should I really have to render?
Is there something wrong in my workflow?

First, be sure that all your render flags (if that’s what they’re actually called) are checked. Go to you sequence menu and put a check mark next to EVERYTHING in the “Render Selection” and “Render All” fields. If there is something here that is not checked, FCP will not render it when you render the timeline. But, when you ETT or PTV, it will render everything to Full/Best quality – it renders these non-rendered files to a temp location and does not save them, so they must be rendered every time. Once you’ve checked all your render flags, go into each sequence and press option+R (Render all), rather than selecting your clips and pressing command+R. This will ensure that everything that you have placed in a sequence will be rendered. Do this first for the deepest sequences in your nese(s) and work outwords (so if Seq. A and Seq. B are nested in Seq. C, be sure to render A and B independently first before rendering C).
Also, if you’re using the PTV options (like slate, bars and tone, etc.) those will always render to the temp render location. This is unavlidable, so you sort of just have to deal with that or work those options into your timeline… but that render shouldn’t take 20 min.
Best,
Ben

Ah!
That explains a lot actually. I’ll try to check all flags next week when I have a fresh episode to work on. All I use from the mastering settings is a 60 second trailer of black, which I doubt would take 20 minutes.
Thanks for the input!
