I just upgraded to a 4core 2.66 mac pro with 5 gb of ram and a 1900x video card.

However, when editing in FCP I am still getting the ORANGE "unlimited" render line on certain clips when I try to playback in the timeline. It stops when it reaches those clips forcing a render and slower work flow.

The clips are uncompressed 640 x 480 with a data rate of 19.9 MB/sec.

I had the same problem on my PB G4 that I just replaced and assumed that this machine would not have the same problem.

Is there a setting, or hardware configuration that might remedy this??

Thanks.
 
on your timeline's upper left corner, there is a pulldown menu where it says "RT"...

click there and it will probably be set to "Safe RT", change it to "Unlimited RT"

that should do it
 
no dice. It is set for unlimited. even low playback quality...
hmm...
 
no. there are no filters applied.

the uncompressed / resolution could be from how I imported it. I don't recall my capture settings at the time (imported a couple months ago). I think the original video source was so dark and unclear I may have deliberately captured to an uncompressed format in order to preserve it as much as possible.

It was a VHS, to DV, imported into FCP. Running FCP 5.1.4
 
ok. so.
The sequence settings suggestion lead me to the manual where it states that multiple clip sources will inevitably lead to this problem which it claims is... just the way it is.

Unfortunately it is a promotional video that is using about 12 different sources.

SO. Either I can deal with it, or export those clips in a different format.

I guess I'll just deal with it.

If anybody has a suggestion that would allow the sequence to read the file without rendering regardless of its specifications, let me know. Otherwise, I think that pretty much does it. Thanks guys!

Here's the deal:

It sounds like you have multiple sources that are different bit-rates / formats in a single timeline. In FCP 6 (FCP Studio 2), this problem with playback has been fixed. As one of the selling points of the program, this will not be patched in 5.1.4. So, if its a problem, your going to have to upgrade, which kinda sucks if you don't have an extra $1300 to burn. I will say that the upgrade is worth it in my opinion though, because you get motion 3, color, soundtrack, etc.
 
actually I purchased my current version from a crossgrade from 4.5... so to get the FCPS2 crossgrade should be about $400... or something like that. Well worth it in the future, but not today... :) thanks.

I've never heard of uncompressed 640x480, why such a low resolution?

Uncompressed SD (which is 720 not 640) is pretty much as high quality as you can capture SD. Not exactly low res unless yer comparing it to high quality HD. ;)

How are you receiving the media to edit? And you mentioned going from VHS to DV. When you captured it did you use Firewire or do you have a capture card in your Mac?

If it was me personally I'd use the media manager to transcode everything to a single format. Having to keep re-rendering everything in the timeline would drive me up the wall not to mention add significant time to the edit.
