CS5 - terrible, freezing performance when previewing Dissolve? at DVinfo.net

Ryan Thom · June 15th, 2010, 05:10 PM

I'm getting a weird problem in Premiere CS5. I'm editing Canon 5Dmk2 footage (the native MOVs, not transcoded) using nvidia GTX 285, intel Q6600 at 3ghz, and 6 gigs of RAM. I was just doing a simple test project when I noticed something wrong.

I setup a Cross Dissolve between two clips. If I scrub over the timeline, the dissolve appears fine. However, if I preview, at some point during the dissolve the footage freezes a few frames into the dissolve, although the timecode is still advancing (i.e. it still appears to be playing).

If I let it continue, after 10 seconds or so, the footage will jump to where it should be, although the playback is now jerky. Clips A and B both playback just fine normally, as long as I don't let it play over the transition..that's when things go haywire.

Just noticed that this is only if I dissolve using two clips of the same footage (same MOV file). If I dissolve between clips referencing different files, then it appears to work fine.

Anyone know what might be going on?

This is a known issue.
Temporary workaround.
Copy the clip you want to use twice in the windows explorer.
Import this copied clip into Premiere and use this as the 'second' clip.
Now your cross dissolve will work as expected.

Thanks for the reply Ann. Does indeed to be a bug in both CS4 and CS5, and apparently only when using AVCHD footage:
Adobe Forums: AVCHD CS4 and transitions problem

Your work around looks good, as well as using something like cineform.

cheers,

I am experiencing freezing without any disolves. I am using mt2 hdv and 5d files. Anyone having similar issue?
