Bigger is not Better

The following references to file sizes are rough approximations.

I had a clip about 10 minutes in length, 1.8 gig (captured from a VHS tape in VV4) that I opened in trimmer, then I opened it in Sound Forge to edit the audio track. The audio was mono, I increased the volume in a few spots and copied the track with sound to the other track, then saved (same filename). It took about 12 minutes to save with a 2.53 P4 CPU. The new file was 13 Gig!!!

Why did the file get so HUGE? There must be a better way. What am I doing wrong?

you are saying that you saved the file....but it sounds like you rendered the file (most likely to uncompressed AVI).

Yes?

Sure there is a better way. Make the changes in Vegas. It use the same FX filters Sound Forge does. Right click on the green icon in the header area of the sound track. Pick the plug-in you need, make the changes. Done.

In fact if all you're doing is increasing the volume in a few spots dropping in a volume envelope and setting points where needed probably will fill your needs. Insert/Audio Envelopes/Volume. Once you see the envelope, (a thin blue line across the middle of your audio track), just right click on the line and "add point", then you can drag the points higher/lower to set the volume over a range. You don't even after to open in the trimmer, in fact doing so just slows you down.

What I do if I wnt to edit in SF is open a copy ofthe audio, then edit it. I don't edit the origional (avi file) and it's smaller then video+audio! :)

Yes, you are correct. In SF there is not a RENDER choice under FILE, but it still must be rendering. I hadn't looked closely at all of the settings at that point until you brought it up.

Thanks for the help.

Just delete the video track, edit the audio and render out as .wav and bring that back in. Alternatively and better just ungroup the a/v tracks and hack away at the audio track. You can mute the video track if thats annoying you.

About the only thing I don't seem to be able to do is totally lock a track like you can in Premiere, from what I can see muting a track doesn't lock it, you can still inadvertently select it and change it.

Right click the event on the track you want to lock - select "properties" and then select "Lock".

I suspect you rendered an uncompressed AVI.

If it was a DV file, make sure to render it to AVI format, DV (NTSC or PAL, whichever your source was). Sound Forge will do a direct stream copy for the video, which not only will be WAY faster, but it will be smaller, and a lossless copy of the original.
