Odd slugish Premiere with Long Mpeg2 file
What can I do to solve this issue?
Premiere Pro CS4 (all updates/that I know of) is acting sluggish and very odd.
I am using a time line setting of DV NTSC Widescreen from the preset menu. My source file is from a live 3 camera shoot cut live on a Tricaster Studio Version 2.5 and recorded to its Drive using the “Studio MPEG” format then transfered via external drive to my main edit machine. The file started out about 2 hours long and was cut to about 1 hour and 40 minutes. The File raw file size is about 32gig before editing.
OK before I go any further here is the workstation specs:
Dell T7400 with dual Intel Xeon E5420 processors (dual quad- it shows 8cores @2.49Ghz)
12 gig of FBDIMM ram
64 bit version of Windows Vista Ultimate (all updates accept for some foreign languages)
Nvidia Quadro FX1700 video card – connected to a Samsung 42 LCD via DVI-HDMI@ 1920×1080
150 gig main internal drive with OS and Adobe Production Premium
1Tb external Esata drive
dual 300gig Western Digital Velociraptor 10krpm drives in raid 0 for video data
(as far as I can tell I have all updates)
OK so I use only the video portion of the Mpeg file and for audio use the MP3 that is recorded at the same time. Upon loading the file into the project there is about a 20 minute or so (conforming) that takes place.. Then I begin working and as long as I’m in the first 2/3rds of the file ever thing seems ok.. But when I even click past that point on the timeline then premiere acts like its on a machine with no memory at all..super sluggish, no video in preview for 5 minutes..not really anything you can do but wait…The last portion of the file is basically un-editable. SO I hit enter for render all, even though I still need to edit. After 4 hours or so I have a green line and get back to work. Great so I get this and nest the sequence…then in another timline do my credit roll..nest that..open a new timeline stick the two nested files together and dynamic link to encore.(btw now that I nested the super slow barely usable thing is back) .Also the title edit page seems to run verrrry slow.All I did in encore was the basics..Chapter marks at interval, end action and such and burn. It takes Like 5 seconds to at the first 80% of chapter makers then 5 minutes to ad the last 3 markers…kinda weird it usuall fly past this. Then on Burn it takes a good 4 hours to transcode.
The resulting dvd played on a standard dvd player to an olivea LCD via component video look fairly nice, but has a bit of an odd interlacing issue at times and an occasional stutter on slow pans that was not present in the original AND it completely left of the credit roll..wierd.
What do I need to change to get my normal good performance for this longer file. I have recently completed an hour long wedding from DV tape and had 0 issues like this.
When I look at the resource monitor the whole computer is never using more that 6 gig even with photoshop 64 bit, encore, and soundbooth open. (For what I do so far)
This is something that I need to do every week, and fast. What Do I need to do to address all these issues. THANKS many times in advance

I have some thoughts, but I hope you get a few more responses to this – lot of info to absorb 🙂
You said – ‘My source file…’. Singular. I don’t know if it’s possible in your workflow, but I’d either recapture, clipping files to less than 4.5GB (for DVD backup). Or, decompress and clip to less than 4.5GB. I usually clip to scenes. I’d much rather have a bunch of little clips than one huge sucker. You would have to re-edit, of course.
The first medium sized project I did used a 20GB DV source file. All seemed well until I began to approach encoding. I can’t even remember all of the stuff that started going wrong.
I’m quite sure that it was the files size that was the problem, never did it again, and problems never happened again.Consider decompressing the MP3 to PCM WAV, 44.1kHz, stereo (assuming this matches your project settings).
I’d recommend encoding out of Premiere with Main Concept MPEG Pro. It will give you more control, better quality and could likely address the slow pan interlacing issue (with tweaked settings, of course).
I often recommend to use task specific software…
Premiere to edit. MC to encode. Encore to Author. Nero to burn.
If you’re using an Encore compliant MPEG-Video file it takes about 30 seconds to write the project VIDEO_TS. No transcoding in Encore.
This will eliminate surprises at this late stage.Are you putting a good lead-out at the end of the file. Maybe 10 seconds or so of black video. At least 5 sec’s for a project of this length.. or go crazy, try 20 seconds – in the MPEG, not as an additional timeline, end-actioned from your main program. 🙂
Also, some system optimizing tips. Probably your best bet, since you’re practically done with the project…

OK The Footage is from a live event. Shot from 3 cameras and mixed live. The mixer (tricaster studio) records a “studio mpeg” and an mp3 file. I also record a wav file with a external zoom. Yes the wav file sounds much cleaner and I’ll use that instead.
Now when you say recapture… I am simply transferring the file from one computer to another. So you think I should find a way to cut the file into pieces and then drop into premiere?
Ill check that other thread. Main concept will have to wait for now. I need to master what is at hand. Once things are a bit more black vs red…then plugins may be an option.
How you you recomend I split this large file?
Thank you.

Oh yeah.. and I will probably never be “done with this project”. This is something we do every week. I would like to streamline this process. We have been burning dvds live…and now want to add quality and features to it.
Thank you
