Thanks for chiming in Bob,
Do you have "scale to frame size" enabled or disabled?
Actually I'm not sure; I sometimes return to PrE after months so suffer "use it or lose it" syndrome; so I've forgotten how to check.
Do you have more than one hard drive and are the files off the system drive?
Actually I do, and they are. I tried moving the clip to the System drive but it didn't seem to make a difference.
What are your project settings?
I use the default settings
The 60D uses an odd frame size of 1920x1088 instead of the standard 1920x1080.
I guess that why I was told to change the "Time stretch" to 99%, and seemed to work; at first.
H.264 video is compute intensive as it is and this will add additional processing to scale or trim. Hopping of the cti is a symptom of the computer not being able to processes the video fast enough to preview smoothly.
Actually that what I suspect is the problem. I think my graphics card may be pulling me down:
You can try Power Director to see if it can manage the resources and process more efficiently.
I've scrubbed that clip in PD12, on my laptop, and it was smooth.
I've also tried converting the MOV file from my Canon to an AVI file and it scrubbed smoothly. Might that rule out the processing/graphics card issue?
ps
I just realized; I wasn't using my 60D when I shot these clips.
The really odd part is that all the clips in the collection; taken over a period of 3 weeks, are AVI; except the one I was scrubbing; that, and a small number of clips; that I took at one location, are 3gp files and the frame rate on them are all different
12.85, 19.23, 13.78, 18.72,13.83 and 29.75; all shot with the same Canon Powershot 630, on the same shoot; within two hours of one another. The file I converted to AVI is 29.97.
Why would there be such a variation in Frame Rate; using the came camera, a ?
