View Full Version : Help: Premiere seems to deinterlace/recompress regardless of settings.

I need some advice here, please. My objective is to have a DivX (or XVid) file with vbr mp3 audio compressed with LAME, all that from the content of my DV camera.

What I have done already: captured my DV file using Premiere 6.5 and the MS DV codec, edited the content in Premiere for long hours.

What I am trying to do: output this edited content as DV format to use VirtualDub to create the DivX with the mp3 audio.

Problem: the DV output from premiere does not have the same quality as the original DV file.

I have unchecked the recompress and deinterlace option in Premiere but the file still looks like it has been recompressed or deinterlaced. When I open the original in virtualdub I can see the interlacing, when I open the edited output from Premiere there is no interlace effect on the frames.

You can look at an image of similar frames form the original and the edited version when opened in virtualdub here (http://www.coms.uconn.edu/ftp/users/crauh/temp/frames.jpg).

Please, can anyone explain to me what is happening and any possible workaround? Also, any future tips on my method for capturing and editing my DV content?

this is strange. i had a similar problem with premiere insisting on recompression.

sometimes it'll work, other times it wont. an easy way to tell is that when you export your movie, it'll say "2 hours remaining" when it intends to recompress, and "10 minutes remaining" when it is just copying...

i have not found a way to force the issue as yet, and the MS-DV codec is absolute tripe for quality. it's strange that de-interlacing is happening though. maybe check your export settings, as opposed to your "project settings" which really only affect previews.

you may end up having to just put up with it, however...

i know there's a frameserver plugin for premiere floating around, though, so you could use that to frameserve directly into virtualdub... i haven't really tried this with success, but i'm sure playing with it would yield something useful.

if you don't mind using premiere's (crappy) resizing algo, then you could export to xvid with the sound uncompressed, then do a direct-stream-copy from virtualdub with this file, so you process the audio without touching the video.

That's terrible news. BTW, all my settings are the same and they all are DV encoding etc. Yet, Adobe Premiere insists on doing some type of processing when I export the movie, either through the MS DV codec or by himself.

Thanks for the idea of doing an xvid export with uncompressed audio and then changing that later, that is something I haven't thought about.

One other question, do you know if it's possible and how can one use other DV codecs with Premiere?

It's always been a pain to output video from Premiere for me as well; I usually just put my projects back on tape (no problem there), but on the occassion I want to distribute a video, it always seems to take longer than I'd hope. I have always achieved the best results frameserving out of Premiere to VDub with the tool @ www.videotools.net. I then encode the audio with BeSweet. Everytime I've tried to export a DV file and then use AviSynth or VDub to open it, quality always seems to have degraded. This is all using the MS DV codec (I really don't see a difference with the other ones, so why bother?)
