Try highlighting the section you want to use, then rendering loop section only to a DV .avi file. You should then be able to use this new .avi file in your project.

I've had exactly this problem myself with a wmv file 90 minutes long.
The issues is as its encoded only for streaming there may be no keyframes in it.
Just one keyfrme at the start and the rest are delta frames.
The best fix is to downlaod Windows Media Encode, its free!
Then re encode, best I've found is to set the frame rate to what your going to use in VV BUT whatever you do make certain to set keyframes every 2 seconds.

Sometimes I find even though I can't keep audio sync in VV so long as I render out the whole file it comes out OK as an AVI. Which approach really depends on what your trying to do with it, how good the resolution is to start with etc.

CW, tried it, and it doesn't work...


farss, I'm pretty sure you hit it right on the nose, but I'm still having some trouble with the fix...


I downloaded Windows Media Encoder Version 9 and tried to encode the file in

"High Definition Quality" (5mbps)
"DVD Quality" (2mbps)
"DVD Quality" (1mbps)
"VHS Quality" (250bps)

With any of those 4 settings, the frame rate remains as 29.97 fps and I'm not sure if there's a way to adjust it...

All of the new files played fine in WMP (a couple of which hit 70+MB in AVI format), but still played very choppy when trying to edit in VV...

Also, I didn't see anything that would allow me to change keyframe settings...


Thanx for all the help...

And if you could attempt to edit the file posted previously, I'd really appreciate your input on how to get it to work....






Thanx again

We've had to use the Windows Media Encoder 9 to re-encode some WMV files that have only a single keyframe at the beginning. These particular media files will show black video frames when loaded in Vegas.

Here's some tips to get you started with WME 9:

1. You can use the wizard for converting a file, be sure to uncheck the "start encoding when I click the finish button" checkbox -- you don't want to start it immediately because the frame rates are all 29.97 for the choices in the dropdown.

2. After you've stepped through the wizard, use View | Properties Panel or click the Properties button on the toolbar to change the encoding settings.

3. Go to the Compression tab, here you can set Video to VHS quality and audio to CD quality (or whatever settings you'd like). As we're going to customize these soon anyway, you don't really have to bother changing the video or audio settings, but this will set the frame size you'll want.

4. Click the Edit button to bring up Custom Encodings Setting dialog, it comes up with the General tab selected. From here you can change the audio and video encoding modes (CBR, Quality VBR, etc.).

5. Click the "xxx Kbps" tab to change the encoding settings to your custom values -- you'll probably want change the frame rate (say 30 fps for this example), and change anything else as you prefer.

6. If you want to save this profile to use again, go back to the General tab and click Export (you may want to change the name and/or description first). I think there may be a bug in WME9 as it grays out the Custom button but it really should be active and selected (it does use 30 fps as it should).

7. Click OK in the Custom Encodings Setting dialog.

8. Click Apply in the Session Properties dialog, and click the close button in the dialog.

9. Now click the Start Encoding button in the WME9 toolbar.


You can find information about your original WMV file (frame size and rate, audio sample rate, etc.) by clicking on it in the media explorer in Vegas or playing it in the Windows Media Player and using File | Properties. You can use these settings as a guideline for the settings to use in WME 9.

Please note that re-encoding can introduce more compression artifacts and the quality of the new media file will not be as good as the original because of recompression.

Hope this helps.
