Seems Like it should work
So I just bought a Canon 60d, and whenever I try to edit my footage in Premiere Pro CS5, the playback turns choppy after about 8 seconds of playback(raw footage with no effects applied), even when I decrease its resolution to 1/4 resolution.
I’m trying to edit 1080p 24fps (H.264 .mov) on my Dell laptop which has a Intel Core i7 Q720 (4 cores @ 1.60) with 4 gigs of ram and Windows 7 64bit and a ATI Mobility Radeon HD 4570 (512MB Dedicated video memory) video card.
Before I bought Premiere Pro CS5, a representative at Adobe said my computer would be more that capable for editing HD video, and it has been for 1440i in the past, but now with my full HD footage from the 60D I just can’t get realtime playback. It seems to me like my laptop should be fast enough for this.
If anyone knows ways of optimizing Premiere or something I would really appreciate it!
Thanks all,
Justin -

It actually may not be fast enough for this – h.264 footage is very lossy and makes the CPU/Ram/Drives work really hard. The video card doesn’t enter into the playback (at least not really in this case.)
Right click and drop the resolution in the Program Panel to 1/2 and you should see better playback.

What is the Hard Drive setup for the media? Same as OS and Apps, external USB 2/3, Firewire, Second Internal, eSata, RAID 0/1/5?
4 Gig is not much for HD editing – 8 would be better.
HDV is only about a 25Mbps same as DV. Canon’s FullHD is more like 50Mbps so that Hard Drive needs more speed than say USB 2, which would work ok for DV, but maybe not so for H.264 from DSLR.
Are you running the latest update?
Are you working within a native Sequence for the DSLR footage?
Let us know ASAP 🙂

Hey Guys,
Thanks so much for getting back so quickly!Jeff,
Yes, I’ve actually already tried to drop the playback resolution to 1/2 and 1/4, and they help some, but the playback is still choppy after like 8-12 seconds.Jon,
I first tried it off of my internal hard drive which is a Toshiba mk5056gsy (500GB 7200RPM SATA), and then I tried it with my external WD Pro Book (500GB 7200rpm ESATA{3GB/s}). It seemed to work a little faster on my external drive, but it will still turn choppy after like 15 seconds. (Both hard drives only have 45GB of free space on them. Not sure if that affects anything.)I watched my CPU and Ram usage on task manager as I played back the footage. The ram fluctuated somewhere between 3.4gb and 2.0gb, while the CPU stayed between 60-20%. (only rose above 50% a few times)
I am running the latest 5.0.3 update for Premiere Pro CS5. (is there another update I should be looking for?)
Yes, I used the Premiere native timeline for DSLR 1080p24. And I tried changing the program window to full res, 1/2, and 1/4, but I can’t get lasting realtime playback on either of them.
Thanks so much for your advice. I really appreciate it!

This is starting to sound like Video Card Driver issue. A 7200rpm internal drive should be giving you plenty of muscle if you drop the resolution down.
Make sure you search for the last known driver that works properly for your card model and PProCs5.5
Or you could have bad RAM. Did you build/upgrade this yourself? If there is a mismatch in RAM modules, there’s a heap of rules when using multiple sticks in certain DDR types etc.
There was a 5.0.4 update but I think it was only for Mac:
DL and install manually or use the updater from Help>Update…

I’m suprised no-one has mentioned the problem of Quicktime on the PC platform (it being a bit slow to decode files in a MOV container).
Premiere could be using Quicktime to decode the files which results in choppy playback. I had this issue with Nikon H.264 files in a MOV container. The workaround was to change the MOV extension to MPG which forces Premiere to try and use its own decoder for the job. Suddenly no more choppiness.
I think it might have been Todd Kopriva who explained the problem in a previous thread.

Jon,
Thanks for your advice. I did update my video card driver, and it seems to help the playback somewhat, but it’s still pretty choppy. (even on 1/4 res)Yea, since I’m running PC the PPRoCS5.0.3 update is the most recent one. (the 5.0.4 is for mac only) I tried the update option on PPro, but it’s as updated as it can be.
I actually didn’t build the computer myself, I just purchased the Dell laptop all together, and haven’t really upgraded any of it’s hardware. It’s a Dell Studio 1557 if you want to check the specs.
Alan,
I tried, like you said, changing the file extension from .mov to .mpg, and PPro did make an .xmp file (and thus decoded the file without Quicktime) yet the result for me was more choppy than the original .mov file. That concept makes sense, not sure why it wouldn’t go for me. Perhaps your Nikon video files vary from the Canon ones.Thanks for your guys’ help. Let me know if you have any more ideas.
