A way to trim clips without having to re-render?

fherr wrote on 12/20/2002, 10:20 AM
VV captured some of my footage as one clip but I'd like to split it into 3 different avi files. The only way I know how is to put it on the timeline, split and delete unwanted parts and re-render the remaining bit as a new avi clip. But I keep thinking there must be simpler way that doesn't require a render. Is there?

Thanks for helping out a newbie.

That's the easiest way to do it with Vegas. Keep in mind though, if your source clips are DV .avi and you want DV .avi for the individual files, then it won't really re-render. It will just bit-for-bit copy the sections into new files without rendering. There won't be any changes made to the material or any quality loss.

Fherr,
Also, if you prefer to have original files, can you recapture the footage from the original tape in three segments? May be more hassle that it's worth, as Chienworks has indicated, as there will not really be a re-render from your original capture.

Thanks! That sounds promising, but when I try it, it seems to take almost as long as other renders I've done. Maybe I'm not rendering it to "DV .avi" properly? I choose Save As Type: Video for Windows (*.avi) and Template as NTSC DV. Is that what you mean by rendering as DV avi?

You have the correct setting - however, it takes TIME to copy GIGS of information. It should STILL be faster than real-time. On a PIII 750MHz it took 7 minutes to "copy"/render 9 minutes of video.

fherr: that should be correct. Are the clips you've captured also DV .avi files? On my 866MHz P3, it takes me about 1 minute to "render" about 4 minutes of DV to DV, so my render times are only about 1/4 or so the length of the clip.

Wow, I must really be doing something wrong. It just took me 17.5 minutes to render a 4 min. 45 sec. clip. My computer is a PIII 933, 512 MB RAM.

> Are the clips you've captured also DV .avi files?

I believe so, if I understand you correctly. They came from my MiniDV camera via firewire to a Pyro card to my hard drive using Sonic Foundry's Video Capture tool, which saves all captured clips as .avi files.

Are you sure you didn't accidentally set something causing the entire thing to be RENDERED instead of COPIED? For example, it is VERY easy to change the level slider below 100%. 99.8% will LOOK identical but will cause every frame to be rendered.

I'm not aware of anything I might have done like that - levels are at 100% etc - but now that I know I must be doing something wrong, I'll dig deeper. Thanks for the feedback.

Okay, I think I found it: clicked on the Custom button of the Render As screen, and "Motion Blur Type" was set to Gaussian as the default. By changing it to "None" I got the render time for that 4:45 clip down to 3.5 minutes. Better! Thanks to everyone for your suggestions.

Hi Frank,

FWIW, when time permits, you might try running a simple test to check your settings:

Drop a clip of DV captured by Vegas into the timeline and prerender it. If it doesn't immediately finish, you can systematically track down the setting(s) slowing you down.


(Sounds like you might be fine, tho.)
