Motion Performance Terrible - any tips?
on Jul 3, 2013 at 2:45:32 pm

When creating a motion project the performance is very bad. Slow replay and stutters.

The project i'm working on consists mainly of:

- kinetic text
- behaviors
- filters
- 4 camera's
- Only a few layers use 3d settings the majority does not.

Laptop specs:

Macbook Pro - Retina - 2012
OSX 10.8.3.
Memory 8 GB 1600 MHz DDR3
Processor 2,3 GHz Intel Core i7
Graphics NVIDIA GeForce GT 650M 1024 MB


Wanting to combine these texts with the video material i need under it becomes impossible.

I've tried to set all render/view settings to default. ( quarter, draft, and disable all lighting shadows etc).
At this point i can only fluently see the material when going through a full RAM preview building.

Any tips? Help? Is there a max when using motion in combination with audio and video? Does motion always become slow when using more than 30 + layers?

Any help would be great thanks so much,

Greets,
Sander

The graphics card plays a big role in Motions performance. Is the NVIDIA GeForce GT 650M 1024 MB supported for Motion?

hmmm. good question.

I have no idea honestly...any way i can find out?

Plus: should this really be a factor? I do sense that in the beginning of the project ( less layers ) it ran smooth. However with my current laptop settings and specs i would recon it should handle the things i am doing now.

Here's where you can check if your graphics card is supported:

Yours appears to be.

In addition to having the right graphics card the key to Motion performance is RAM and lots of it.

Because of its real-time architecture Motion loads everything into memory. If you don't have enough RAM, it starts using virtual memory which really slows things down.

If at all possible break your project down into smaler sections as the longer it is the more RAM it's going to suck up.

Here are a few general performance tips courtesy of Patrick Sheffield's invaluable Motion handbook.

Turn off thumbnail previews.

Don't have any layers selected when you begin playback - this avoids unnecessary redrawing.

If you're using RAM preview then clear it often as Motion keeps them all in RAM for use in undos.

Keep motion blur turned off until your final render - this is a major performance killer.

Turn of layers that you've finished building if you don't need them.

You might even think about pre-rendering elements and bringing them back in rather than trying to run everything in real-time all at once. Export a layer or group using Export Selection - this enables you to choose to have the new layer come straight back in to your project.

If you're using particles keep the particle count to a minimum as you work and only turn the number up for your final renders.

In general try to keep your complexity down as you work especially if you are just experimenting with things. You can always crank it up later.

Make sure you use Fixed Resolution on any groups where you can get away doing this to avoid computing offscreen elements, especially particles.

You have 4 cameras can you break it into 4 different projects?

Wow. Great tips Simon. Thank you very much for your time and detailed suggestions.

I will try them all and get back and post them here.

And one more I forgot - got to your Motion Preferences Cache settings and turn up the value of the Memory Cache to use more of your available memory.

EDIT: And one more one more thing - what's the codec of your video files? If it's Animation, Motion doesn't play nicely with this so you might need to transcode for better performance. Make everything ProRes if you can ...

Nice!

I will turn it to 100% instead of the current 80% then.

Thanks! :-)
