Jerky playback in CS4

Chris Nelthorpe Dec 18, 2009 9:06 AM

Hi guys,

I downloaded the 30-day demo of Premiere Pro CS4 last night to edit my .mxf footage, but the playback is extremely jerky when I drag a single clip to the timeline. My PC has a 3.2Ghz processor and 2.0GB of RAM. Is that too little...? The footage was shot on an HVX200 at 720PN, 25fps.

Failing this, I'd like to convert the footage into another format so I can order it in my copy of Prem Elements 7. Can anyone suggest a comparable format so that the quality won't be too badly affected? The strange thing was that when I tried exporting a clip last night in uncompressed .avi format, which made it about five times the size of the original .mxf format, it played perfectly smoothly in Elements.

Confused,

Chris

Uncompressed or Lagarith or even HuffYuv are the only choices you have that make sense with the trial.

Chris,

As the PrPro trial does not allow anything MPEG, you will be limited in that respect.

I like Harm's suggestion of going to the Lagarith. When properly installed, PrPro and PrE can use it. It takes slightly longer to work with in PrE, than straight DV-AVI Type II, but does OK.

Good luck with the trial. [One odd note: the PrE 8 trial (and many previous) does allow MPEG work. My guess is that because the PrE trial watermarks the output, Adobe is able to get around the licensing issues with MainConcept and the PrPro trial.]

Logarith sounds like something out of Lord Of The Rings, but it's a very useful piece of kit. Many thanks for helping solve my problem, guys...!
