green screen workflow
Hi guys and gals
I’m currently editing togther some course material for a TED speaker which is all shot against green screen with his keynote edited behind. There are four courses, each is about and hour long and is split into 5 min chapters.
I’m at a stage where i want to start exporting the chapters but it’s looking like 30mins per minute. Obviously this is going to take an age to export all 4 hours of material and i don’t really want to sit here and babysit it for the next week.
Has anyone got any ideas on how i can reduce that time either in terms of workflow or rendering etc. or any batch export solutions if they even exist…

I think you can do a bit of automating this in Compressor, but I’ve never tried that.

I really don’t catch on which stage are you.
Have you applied the key in FC and now are you trying to export the picture with the new background?
Then you want FC renders all your chapters (sequences?) without you to take care of the render/export?
In FC you can only export manually (Export QT Movie or whatever other option).What you can do is to make FC to render all the sequences while you are away.
Once the sequences are fully rendered, exporting is fast.
– Open the sequences you want to render and in USER PREFERENCES > GENERAL > AUTO RENDER.
Set it so FC will start to render automatically, few minutes after FC is inactive.
– Keep checked “Render RT Segments”.

Yes, thanks Rafael. I did a couple of short tests earlier and it looks like the best bet is render everything first overnight as exporting following render is dead quick. I just wasn’t sure earlier that the key would be part of the render and therefore a waste of time. It’s still going to take about 80 hours to render the whole job though 🙁

Actually, any idea why autorender starts up and tells me 50 mins but if i instigate a full render it says 13 hours!?

[James Pryce] “Actually, any idea why autorender starts up and tells me 50 mins but if i instigate a full render it says 13 hours!?”
When you order FC to render and FC start to do it, the progression bar do not know how much of the time-line needs to be rendered and which effects are on the sequence.
FC calculates that the whole sequence will be rendered at the speed is rendering at that moment.Imagine that your sequence is one our long but have only some heavy-to-render effects on the first few clips. FC may tell you that will need a few hours to render all, but in fact, after those first clips have been rendered the progression bar will start to speed up and the “remaining time” will go down very fast.
