slow renders in fcp timeline, fast exports in motion ??
on May 17, 2007 at 3:08:19 pm

i've been noticing crazy long renders of motion projects in the fcp timeline (9+minutes), but really quick exports from motion (1 minute). i haven't done any scientific testing yet. just wanted to ask if this is a common thing. I'm thinking it might have something to do with motion blur?

thanks

What are your video settings?

We need more info from you to answer your question.

I just noticed a huge render time discrepency rendering an animation as animation losless codec vs. a DV codec out of motion. I'll bet that's where your issue is.

Are you rendering the same uncompressed 8bit out of motion as on the timeline? (I've noticed banding in uncompressed 8bit gfx renders as opposed to animation codec imported into an 8 bit timeline.)

I'm just passing through here, but that's my 2 cents.

[dave garcia] " (I've noticed banding in uncompressed 8bit gfx renders as opposed to animation codec imported into an 8 bit timeline.)"

You will do if you have a gradient or similar in 8bit. The animation codec varies its bitrate according to the complexity of the frame.

Try clearing your RAM cache before exporting, I've noticed things speed up after that.

Doh,

Remind me to read the whole thread and not just the post when I get emailed!

What version of FCP are you using as pre 5.1.2 wont use the graphics card
