  • FCP6 Extremely long render times

    Posted by Andrew King on June 6, 2007 at 2:39 pm

    Our FCP timelines that include .motn elements have seen huge render times – a four minute timeline will take 8 hours + to render and give “Error out of memory” messages if you try and render more than 30 sec hunks of the timeline!

    Timelines and media are apple UC 10bit.

    The work around is to render Motion elements in Motion and then lay them into the FCP timeline – this gives us 12 minute renders of that same 4 minute timeline.

    Anyone have any suggestions as to why the motion 3 files are taking forever to render inside FCP6.

    Thanks!

    I’m having the same problems to. I think they upped the quality on the Motion File render if you go into the Sequence Settings you can uncheck the render Motion files at best quality this will give you better render times but the quality drops. After looking at the best and the step down, I’ve opted to stay with the best. My 58:30 is taking close to 5-7hours on a 3ghz Mac Pro.

    Devin –

    I’m seeing the same outrageously long render times, and I too figured out the adjustment to “normal” instead of “best” quality for speeding up rendering. The question for me is why has this happened – with FCP5 and Motion2 I was able to get high quality at a much faster rate than with Studio 2 – I don’t see this as an upgrade, more like a disaster.

    I switched to the Normal and my proofer who is not tech minded noticed a difference in quality right away.

    i know this sounds silly but is your motion project setting the same as your final cut project? just thinking that fcp may be doing a conversion of formats/aspect ratios which would explain long renders with only motion media?

    The settings match, One of my projects was even upgraded to FC6 mid project – the same motion files that were rendering fast in FC5 are now slow in 6.
