Can you Smart-Render Sped-up Clips in Sony Vegas?

MadMaverick wrote on 2/24/2015, 3:21 AM
I'm working with DV-AVI footage. I have a clip that I'd like to speed up, which I've of course done by holding down the Ctrl key and dragging back on the clip using the mouse. I drug it back as far as it could go, but I'd like to speed up the clip even more. Are there any other methods of speeding up footage in Vegas?

If not, than I guess the only option is to render the clip, then re-import it into Vegas to speed it up some more. I've read on here before that smart render is only possible if there is no change to the video... so I guess that speeding the clip up would count as a change?

I've also read that to properly smart render trim video (which this clip is) that I should use programs such as Womble, VideoRedo, TMPGEnc Smart Renderer, AVS Video Remaker, Smart Cutter, etc. but not Vegas.

Any help would be appreciated.

"Smart render" is making a bit copy of the source. That's impossible if you want to make any change to the source.

Max in one go = Ctrl drag for 4 times, then Velocity Envelope 3 x, making 12 times.

Beyond that, as you say, render and start again ...

Do as Peter suggested but save it as a veg file. Import that veg file back into Vegas and speed up as desired. No rendering of any kind needed until your final step.

Thanks guys. I didn't even know that you could import a veg file into Vegas. I'm sure there must be some other advantages to doing that. Know of any?

Also, can you smart render if your clips are just trimmed?

Vegas claims to smart render MPEG2 under certain circumstances but according to my investigations it is flawed.

Any change at all = no smart render.

That said - what is it you expect to achieve by smart rendering in this case?

What's the big deal about smart rendering?

I've been earning a living with Vegas for 20 years, and smart rendering has never been important to me.

If you're working for a live newsroom and need product within minutes, maybe, but ..... ?

Mainly no loss of quality, and potentially fast output. Only Vegas 9 "smart" renders quickly.

Considering that the source is DV, a sped up version could be smart rendered to DV by the simple expedient of trimming out unwanted frames. Say you wanted to speed it up 40x, you could keep frame 1, cut out frames 2-40, keep frame 41, cut out frames 42-80 ... and so on. When you render to DV Vegas will see it as a series of unmodified 1-frame long events and will do a 'no recompression' render.

Time consuming? Yes. But, a script could do this. I'm pretty sure such a script already exists somewhere. Was it John who wrote a 'speed up by any amount' script that does this?

Regarding smart rendering, it is wonderful for people like me. I render a big project, then discover something is misspelled or a dissolve is missing. With smart render, fixing it and getting a whole new mpeg file for authoring takes minutes, not many hours.

Yep, this script

I use Vegasaur - maybe the most useful tool for Vegas I've ever bought. You just set whatever time you want the clip to be and click 'apply'. Brilliant.

Plus 1 for Vegasaur. This reasonably priced set of scripts has saved me countless hours of frustration. This past year, I compressed (sped up) 4 hours of video into 1 minute! Amazing.
