Force Render
 

Occasionally despite the yellow bar i get stuttering playback and would like to render those sections.

Aside from sticking an effect on it is there an easy/official way to force a render of a section?

It also begs the question *how* does PPro determine that there's a yellow bar?

Press the "Enter" Key when you have clicked on the timeline.

If only it was that simple!

Because the line is yellow PPro assumes no rendering is needed so will go ahead and play then stutter. Am i the only one seeing this?

If i add a filter so the line goes red then that will *force* a render before preview, but i assume this is possible without dropping an uneeded filter on the line.

When people see Yellow does it *always* playback perfectly?

Ah,

CS4 or CS5?

Mine plays fine. What is your source footage and PC spec?

CS5, source is a variety - XDCAM, H264 and Cineform. There's a couple of places with layers and a transition that PPro reckons is yellow but playback causes stuttering and chokes up the timeline afterwards as well. I have some ongoing problems with cineform that may be causing this but a simple force render would be nice.

It's a quad core with striped array, it ought to be okay...

How is the yellow determined? PPro must decide somehow but it wouldn't know your datarates so how can it determine real time playback?

Try dropping your preview quality down to half or quarter res if not down already? My i7 with Mercury Playback Enabled didn’t like full res.

Do you have a Nvidia GFX with more than 765MB of VRAM? for MPE?

David,

yes it's a 1GB 285 GTX bought especially for this. I don't believe that makes much difference, i think this issue is overall throughput. even if you have half res the source files are decoded at maximum res (i'd assume)

Harm,

One of those Doh moments for me, yes that does the trick... Many thanks!

I'd still love to know whether i'm seeing normal performance or whether i have a bottleneck somewhere.

Are you using a Raid? If not, then it could be that your hard drive is struggling to play the footage hence the stutter. Doesn't sound like it is a GPU or mercury engine issue. Could also be down to how much RAM you have?

I'm running scratch discs with RAID 0 and also have 8GB, i don't think that's the bottle neck but you never know. I may clean the raid up as there's some random stuff dumped on it.

thanks
