Duration of footage changes after re-opening of project

I've spent hours trying to figure this out and after little success doing a search I don't know what else to do.

I'm hoping it is a simple problem that I've just been too silly to solve.


I did my edit, all was fine, then went to bed. Next day, I open up the project and half of the cuts on my timeline are black with no audio.

The actual footage's length is an hour and plays fine directly via media player etc, but for some reason, the source footage appears as no longer an hour in PP but as 15 minutes.

I've re-linked, re-rendered, changed drives, tried changing duration... nothing!

Really hope someone can help, thank you in advance!
 
What type of material is the original footage?

Do you have a BAck up Project FIle ( or an Auto Save Project) that you can try?

Otherwise ... try importing project into a new Project.


Lumiere said "Because its Premiere,thats normal you should expect everything from PP..." because he is not very BRIGHT.
 
Thanks shooter.

I had a backup on another drive and tried opening it, and the exact same thing happened.

It's really bizarre because the .mpeg file plays fine at the full-length in Windows media player etc, so it's not an issue with the file.

I will try importing the project into a new project and see how that goes.

Thanks :)

And Lumiere, whilst I prefer Final cut over Premiere, I do so only marginally as Final cut also has problems :)

Anything to do with machines!
 
It is an issue with the file. Mpeg is not usually very successful as editing media (especially with Premiere)

Can you convert the mpeg to an avi (or mov if you are on a Mac).
 
as a long term premiere user,i sometime had these kind of problems.Or the problems anyone can never give an explanation.I am fun of premiere but it really but really sucks.Don't you see high compression of premiere,even in uncomp..exports..It destroys hole quality,premiere should leave this amateur student program profile.They tried in cs3 but not enough.I am planning to move to avid slowlly and don't know how am i going to get use to a new software which i less idea..:)
 
Ok this is so random.

I used CS3 to open one of the older PP 2.0 projects, and now the footage is appearing... but, is playing each cut about 3 seconds too early.

Something random is going on, but now that I can atleast view the footage, I might make adjustments and export the timeline with no effects/transitions so I have something to work off if the **** hits the fan again!

Really intrigued as to what happened though! Perhaps PP was just having a whinge?

No it does not destroy quality. As a side note you really should check punctuation and spelling when you write, it's hard to read. Premiere, like almost every other program I know of, has the occasional bug, such as this time duration problem. Now does this warranted blanket statements about it's ability as an NLE? No, it does not.
 
MPEG is compressed and not suitable for editing in Premiere!

The compression means the audio and the video are not in a "parallel stream" and the info is stored in packets. When you make a video cut you may be missing the audio information and that throws everything out

There is screeds of information regarding this on this site: Seach "mpeg"

Also check the PPRO Wikipaedia also.
 
Thanks for that shooter, I had heard that quite a lot.

However, all my captures from tape seem to be mpeg. What format should I be using in PP with HD footage, and how do I capture to this format? (or do I just convert to avi or something?)

Thanks :)
 
Tom, Projects created in older verison of Premiere Pro than the one you use should for the best resutls* be finished in the version that created them. IE, if you cretaed a Project in Premiere Pro 2.0, finish that Project in Premiere Pro 2.0.

What version of Premiere Pro CS3 are you using? Some of the issues you describe indicates that you are using 3.0.x. Upgrade to 3.2 and you problems will probably go away. To update: Help > Updates

*Best results=No strange issues when editing
 
I shot on MiniDV tapes as HDV.

I've been using Premiere Pro 2.0 (no updates), and just tried CS3 to see if it worked (just straight cs3 with not updates, as a demo).
 
I realise this is Demo version but the Updates (3.2.0). are supposed to have resolved some HDV issues.

Hopefully yours.


You may need to purchase to get the updates.
 
For a less expensive temporary workaround, try installing the 30-day demo version of Sony Vegas. Import your MPEG footage into Vegas and export it as an AVI file. Then you should be able to cut the AVI file to your heart's content in Premiere.

Good luck!
 
Thank you David,

I'm giving that a go now.

AVI is the best format to edit with in Premiere so I've heard... I'm struggling to find a suitable form of compression though.

Uncompressed blows it out to a ridiculous file size, same with JPEG2000?
 
Sorry for the delay, got a nice copy of CS3 and installed the update. Things work better, but the edits are wrong... as in the wrong start/finish cuts but the timeline is still intact.

Something must have stuffed up.

For future reference, what HD AVI format/compression should I be using?

ADD:

Also some of the clips on the timeline have the waveform appearing, but no audio is being played.
