Motion HD performance issues
on Dec 21, 2009 at 2:41:12 pm

I'm using a Canon XH-A1 HDV and when I send to motion the video won't play in real time. The video/audio are off sync and it's painfully slow, it reminds me of the days I had a Dell it's so bad.

I'm using an Intel iMac with 4GB of RAM and the HD footage I'm working with is about 15 seconds. I'm spending more time waiting and guessing on time syncing with effects that makes editing a nightmare.

I tried changing to third quality and un-checking field rendering, lighting, & motion blur but it's just not playing smooth.

Any suggestions? Hardware, software, performance enhancements?

How much footage are you talking about? Motion tries to load your entire project into RAM so that could be part of your issue.

Also decoding HDV on the fly requires a lot of processor time, try making it into DVCPROHD or ProRes first.

I'm only working with about 15seconds of HD footage at a time. I'm really just apply a simple variable time remap and putting on a few graphics. I have 4GB of RAM on my imac is that sufficient? I re-captured in pro-res but it made little to no difference.

Is my processor not powerful enough? The capture scratch where the footage is pulling from still has about 500GB left of storage. Would upgrading to leopard, getting a RAID, a new iMac, or some simple setting changes correct this? It's near impossible to work when I'm fighting against data rate, I literally have to guess on timing.

Are you using optical flow in your time remap? That would certainly slow things down. If not, consider doing your time remapping in FCP, then just add the graphics in Motion.

I just have frame blending to "none" in Motion but I'll see if doing the time remap in FCP then adding graphics in motion helps.

Motion gets speed from the graphics card- the iMacs are slow in this regard. Not much you can do other than upgrade.

Noah: What are your thoughts on upgrading? Would the new iMac be ok? Is the 3.06GHz Intel Core 2 Duo sufficient or is the 2.66GHz Intel Core i5 the better option?

It's the graphics card where the iMacs let you down.
Check the minimum specs for Motion and compare them VERY carefully against what's available for the iMacs. Spencer likes his lappy for his Motion work. Myself, I can't imagine working on a portable.
