Exported AVI is horible

[georgyboy]

Hi,
I have finished editing all the video on my timeline, went to export as uncompressed AVI and it came it out horrible. It looks all jumpy with horizontal bands as well as the sound skipping beats.
The footage has been imported from my WinTVR card (from video player). When i play the finished movie from within Prem Pro everything looks great and plays correctly.
Any ideas on how to fix?
Thanks

What are your project settings?

What are your export settings?

If you're going from a smaller resolution to a bigger one (ie 640x 480 > 720x480 ) you will run into problems.

My export setting were for Microsoft AVI, no compression. I didnt change the size of my project. And my project settings are PAL DV 768, I think my problem might be that frames have been dropped during the capture stage. I captured the footage from a VHS tape thru my WinFast PVR capture card. The tapes being a couple of years may be the source of the problem?? I dont really know, am still new here. Thanks

You will probably need a DAC100 in order to compensate for loss footage (dropped frames) and Im not sure on the quality of that particular card you are using.

Microsoft AVI is a really bad codec. Go UNCOMPRESSED if at all possible.

Thanks for the advice, but i am little confused. How do i go uncompressed?? I thought thats what i did. I chose Microsoft AVI and then ticked no compression. Is there another way to get an uncompressed file??
Where would i gdt a DAC100 (and what is it used for)??
Thanks again WizyWyg

DAC100 (google for it, I can't explain it correctly)

Anything codec that is in the list is something that is compressed. Microsoft AVI is not an uncompressesd format

In your project settings, under Video, choose NONE for your Windows AVI settings. Dont choose a codec.

Hello.

I'm following along too, and am slightly confused by a previous statement.

In Premiere 6.5, when I Export Timeline, and select file Settings, and am looking at the General tab, I have to select either MICROSOFT DV AVI or MICROSOFT AVI, or a slew of other not-very-applicables. Then on the VIDEO tab, you can choose NONE, but only if MICROSOFT AVI was selected previously.... (If you had MS DV AVI, you can only choose an MS DV NTSC or MS DV NTSC PAL setting for codec.) I think this fact that you have to choose MICROSOFT AVI for file type to get the NONE in Compressor field is what georgeboy was talking about earlier.... that he didn't have a choice but to choose MS AVI. So, the question remains, is a file exported to a MS AVI file with NONE as codec an uncompressed format?

Also, does anyone know the practical difference between MS DV AVI and MS AVI?

Another question, and sounds kinda newbie, but.... which resolution setting is the standard DV format, the most fitting for 4:3 NTSC broadcast, and standard for MPEG2 encoding for DVD (for U.S.): 720x480 or 640x480? I knew, but after reading some posts, I've been shaken from what I thought I knew. 640x480 mathematically makes sense for 4:3, but my standard setting for MS DV capture is 720x480. Is it 640x480 if captured analog with square pixels and 720x480 if captured DV with .9 pixel shape?

When importing DV, the standard pixel shape for 4:3 NTSC DV media is .9 right? When exporting to uncompressed AVI for subsequent MPEG2, or straight to MPEG2, should it be .9 or 1 (square)?

One more. When I start a project, I have traditionally chosen the Microsoft NTSC DV Standard settings... Should I be choosing Custom, and selecting settings with no compression, .9 pixel shape, 4:3, and 720x480? File size is not an issue - keeping original quality integrity until MPEG encoding IS the priority.


Thanks for patience to tackle my questions.

DV AVI is still a compressed format. Microsoft AVI (it just means that Audio Video Interleave is the only MS approved video format to use ) you can choose none. for DV AVI you have to use the native configuration.

in my premier, AVI is just listed as AVI. It differs from system to system but as long as you can set it ot UNCOMPRESSED or NONE, you are good to go.

I am having similar issues with microsoft AVI. My impression is that the stuttering and lined image is due to my system which is pretty fast having trouble playing the files. I notice when I play the uncompressed AVI's off the timeline premier automatically lowers the quality for smooth playback. I've also noticed that after caputuring if I export with uncompressed ms AVI the file is hugely increased in size. Why is this, why does moving a file like this actually add to the file size and therefore hinder smooth playback?

How large is the resulting file. Sometimes, Windows will "choke" on a large file (ie more than 1 or 2 gigs). I find that when I load a large file (1.5 gigs) Media Player will choke and forget getting it to play in Premiere.

JUst cut your reserouce usage (ie anti=virus (disconnect yourself from the net if you do so), background programs) and that improved performance significantly.

I'm talking tens on gigabites. Even a minute comes out at about 6GB and the data rate is 29.75mb/s which seems a bit hefty. I'm running XP pro on a scsi drive with seperate 4 x 7200rpm ATA raid array for video. I'll try doing what you say with background applications and give it another go. One reason I need to rerender these files is that I'm editing a 2 camera shoot, I've synced up seperate audio to the the two files and I want both source files to to have the same code i.e the timecode in one coresponds to the other. the only way I know is to export the files once they're trimmed and synced and re-import. Any better ideas?

Thanks

Defrag . And if you're regularly using large files, make sure the computer is only used for digital editing.

Assuming you are using uncompressed AVI, what is your settings of each clip you're working with, your project settings and your export settings?

What is the purpose of your project?
