Working with MPG files in Adobe Premiere Pro ==> LAG!!!

[Zjaaspoer]

(I'm new here and don't know exactly in which forum to post this, I hope this is the good one!)

Hi,

After a painstaking time of getting mpg files from my Sony DVD cam https://www.videohelp.com/forum/viewtopic.php?p=1160781#1160781, I want to edit my clips in Premiere. Now I converted all my files to a mpeg2 coded .mpg file. But here’s the problem. It’s so SLOW in premiere. As you can look up I have a top of the line PC for editing. Yet when I scroll through a clip in premiere it has a lag of about a second. When I used to work with captured DV files (on a slower computer) the reaction to the sliding of the time bar and other operations was instant. Working with this lag is impossible. So I guess the mpeg2 format is giving me a hard time?

Can anybody confirm this and then maybe tell me what best I could do (convert to some kind of avi file?). I doesn’t matter if the files get 10 times bigger, I have the space and two raid0 10.000 rpm disks . I just want premiere to respond instantly to my inputs. Btw I don’t mind terribly if the quality goes back a little bit in order to get the speed back!

The reason why you are experiencing issues with Adobe Premiere Pro is because it is not designed as a native MPEG editor. You will be better off converting your video to any of the input video formats Premiere Pro actually does support i.e. AVI, MOV, DV. I would go with DV format.

Another thing you can do is to use DVD2AVI (see the video encoder tools section.) This will create an AVI wrapper file and frameserve the MPEG file to Premiere. I have used this method in the past when I wanted to re-edit some DVD movies I have. It may work for you.

Check out the chatter on the MPEG topic at the adobe.com Premiere Pro forum.

Hope this helps.

your lucky... Every time I try to do simple mpeg2 editing in premiere the damn program crashes...

use womble if you want to do native mpeg2 editing...

main concept makes a plug in for premiere to edit mpeg files -- other than that , dont bother to try as mentioned above ... mpeg is not meant anyway as a edit format

Why in the world did you buy a DVD cam if you intended to do some editing on a computer?

[BJ_M]

that question was in my mind also ...

[Zjaaspoer]

I didn't buy it. I just borrowed it from a friend for fun. I realized this problem to late.

But anyway. I found that I have two options. Both involving Mainconcept. The first is to use the MPEG Pro plugin for premiere to edit the mpeg2 files. The other option is that i convert the files (well, i allready did...) to the mainconcept DV format and use these Avi's in premiere, so i can edit in the native avi format.

What do you guys advise?

use the DV format or I also like picvideo mjpeg r3 (you'll have to buy it) good quality, edits smoothly (in premiere), and some space savings... What more can you ask for? :P

well since those options are both the ones i suggested -- either one will work ..


the mpeg plug in will keep best quality though and be faster in the long run

I don't want to hijack this thread but I never found editing MJPEG files in Premiere that satisfactory. I capture video in MJPEG format using a DC10+ card (and sometimes using a Hauppauge card and the PicVideo codec) and tried to edit those in Premiere Pro (tried both 1.0 and 1.5). While they edit okay, when outputting MPEG (framserving to tmpgenc or mainconcept) the output file would lose audio/video sync - about 0.5 s each 20 minutes of video. I asked around on the Adobe support forum and they weren't able to explain it.

Out of interest I tried editing the files in Vegas Video (using the trial version) and the sync problem does not occur

However since my main interest was just to edit out ads, Virtualdub does that fine and is free!

I've never experienced audio-sync problems when using picvid mjpeg... *shrug* the only difference is that I tend to encode with procoder.

[lchiu7]

Interesting. I tried both Morgan and Picvideo codecs and tried both encoding to MPEG2 using the Mainconcept encoder builtin into Premiere and also frameserving externally and the problem occurred

The problem also occurs in this way

1. Import the MJPEG video. Play it - sync is okay.
2. Move the entire video to the timeline qnd play it from there. Now the sync problem occurs

So it seemed to be independent of encoding
