Any way to print to DV tape without rendering?

fherr wrote on 4/16/2004, 11:10 AM

I have one hour video in my Vegas Video 3 timeline - essentially a one-take continuous movie of an academic talk. I cleaned up the audio and now want to send it back to DV tape. When I try, I get a message saying that "over 80% of the movie needs to be rendered, do you still want to continue?" I said yes, and it took all day to render over 350 pieces before sending them all to tape. Adn then when it did send the thing to tape finally, the result was unusable - all the video was choppy.

Is there a way to send the footage with the cleaned-up audio to tape WITHOUT all that rendering?

Thanks in advance.

Normally changing just the audio won't take that long to render. Do you have any effects on the video track, is the opacity set at 100%??

The only thing I did with the video is add a fade-in at the very beginning and a fade-out at the very end. Could that be the problem?

No, that shouldn't casue the problem, it should only render the fades and not the whole thing as long as the video you imported was a standard AVI-DV file.

No. Something else is up. If the image is DV video and you render using a matching DV template then something is wrong, like an effect being added or opacity slider bumped.

Essentially, if you never changed the DV video then the video stream shouldn't require rendering. Just the fades and then the audio.

You should do some smaller test renders to shake out the problem. Another option might be to render just the audio to a new track and then turn off the old audio track. Check for sync, of course.

I should also mention that the way I cleaned up the audio was to bring it in to Sound Forge, do the cleanup and save it as a WAV file. Then I deleted the original audio track and replaced it with the new WAV file. Is THAT the problem maybe?

It shouldn't, audio normally renders extremely quickly. It's normally something in the video that is causing the problem. I'd go back and double check the Opcatiy of the video track, make sure there are no effects or color correction on the video track at all. Make sure the video isn't time-streached or anything like that.

Maybe as a test you should turn off the audio tracks and then render (part of)the video only. It ought to go real quick. If not then there's something on the video stream.

"is the opacity set at 100%??"

I agree with Jason. I bet this is the problem. Check your video track header and make sure the slider is at 100%.

You have SOMETHING selected that is modifying the entire video track. If that isn't it, try posting the VEG file somewhere where we can look at it. Maybe one of us can spot the reason (no media is needed - just the VEG file)

Thanks for the ideas! I dug deeper and found that in the "Conform timeline to this format" area, under the NTSC DV Template setting, "Motion Blur Type" was set to Gaussian. Don't know if that's the default or if I changed it at some point, but anyway I set it to "None" and just tested printing the first few minutes to tape, and it worked fast and smoothly. Thanks a lot guys!

That's great!

Funny thing though. I can't find this setting in the Print to Tape dialog.

I'm still using VV3 - maybe they changed it in VV4?

(I'll be upgrading as soon as they get me a new computer with DVD burner - can't wait! Though judging from the recent buzz, maybe I should wait a bit for VV5!)

You won't have to wait much. Just wait till there's a demo and take a look at it. Probably available really soon. Announcement should be Monday, I hear.

Quick note, motion blur is now part of the video bus of Vegas 4. "Ctrl+Shift+B" and then insert envelope

Ahhhh. That's it. Thanks.

You can use this script to quickly check all video and audio event levels:

[Edit] Whoops -- I just re-read and realized you are using Vegas 3. No script support. Sorry.

Thanks anyway though - I'll be upgrading in the next couple of weeks and will try your script!
