Major slowdown problems...
on Sep 22, 2012 at 5:35:58 am

Hi all,

I am having slowdown with red bars appearing in my timeline affecting my PiP. (That means processor stress right?)

I am running on a Mac Pro 10.7.4 w/ 2 2.4 GHz intel xeons w/ 48 GB of RAM....
Running MC 6.0.3

It should be butter right?

It's a simple AMA link to some .rev files for an editing class but the slowdown is even worse with my 7d AMA link, any advice?

Thanks

If these are files from a 7D then they're .h264. That's a terrible codec to edit with and Avid doesn't do well with it. Select your master clips in your bin and transcode them to the DNxHD flavor of your choice. If you need to, relink your sequence to the transcoded clips. Then it should be smooth as butter. Or just render your timeline, but you'd do better to transcode. AMA kind of sucks to edit with, and .h264 is even worse.

I'm concerned that whoever is teaching this class, didn't tell you that AMAing 7D footage and editing that directly without transcoding was a bad idea. The teacher needs to tell you these things.

Thanks for the fast reply. How do you recommend to transcode? I've used mpeg stream clip in the past and have found my dnxhd footage to come out very noisy.

Could the AMA link to the .revs explain the slowdown? They are just sd 480i files...

What's a .revs file?

If you already have AMA links to the footage - just select the clips in the bin and select "consolidate/transcode" from the Clip menu and choose codec of your choice from there.

As mention already, H.264 is not an optimized codec for editing - and another factor to consider is the speed of the hard drive and its connectivity to the computer. This also can adversely affect performance. Especially when doing two input type effects such as PIP, etc.
