rendering parts of project
on May 7, 2014 at 7:47:57 am

In Adobe Premiere you can render a part of project and then... if this section isnt modified, the final rendering goes faster. Is there any option like this in SV12 or SV13 Pro?

Vegas can render part of a project yes, but as you highlighted in
Premiere Pro, a feature that does exactly that isn't present in Vegas.

Hi Grzegorz Kwiatkowski,

I do it all the time. You can always highlight a portion, copy and paste that portion in a new version of Sony Vegas Pro 12. Also, render a portion right from the original timeline. Remember, give it a new name for saving. Whatever you want to do.

Happy Travels

Yes, it does. Go to Tools | Selectively Prerender Video... Shift+M. This will take any video that requires processing and pre-render it. You can also make a timeline selection to only pre-render that area. If you don't move it or alter it in any way, this pre-render file will be used in the final render.

In addition, if you select a format that Vegas can SmartRender that section will simply be copied to the output file with no additional rendering needed. If not, it will still be used instead of processing the video. Look up SmartRender to see which formats are supported. I'd recommend using Sony MXF because it renders fast, looks great, and can be SmartRendered.

John, I am working in broadcast industry. The final output must be Quicktime mov (DNxHD or Prores). Will prerendering help me with projects with such output?

You are not gonna get Smart rendering with those, thats part of
why i mentioned earlier that Vegas handles this process differently.

It will help in so much as it will pre-render any FX and other video processing so that they do not have to be processed during the render phase. So if your renders are taking a long time because you used some heavy FX like chroma key, then you may benefit. If, however, you don't have a lot of FX then the pre-render may actually take longer than it would have to just process the video once during render because you have to factor in the time it takes to re-redner the video. Only you can measure they benefit.

You will also get smoother timeline playback so that's an additional benefit of pre-rendering but if your playback is already smooth that it's just a waste of time.

BTW, you'll need to deliver Avid DNxHD because PC's cannot "legally' produce ProRes. We delivery Sony MXF HD422 to PBS and they accept it just fine so the whole "broadcast industry" is not as Mac fixated as your statement implies. ;-)

John,

I just tested it. Prerendering parts of project didnt speed up rendering DNxHD. It was the same.

Yes, I output DNxHD everytime. Its a pity I cant speed up rendering process using smart rendering in SVegas. Almost whole broadcast industry bases on quicktime. This is reality.

I was hoping they would implement it in the new version.

Yea, QuickTime is not one of the formats that Vegas can SmartRender. If you did a lot of heavy FX processing or are using an acquisition format that is difficult to play back, then even prerendering to DNxHD would help because playing back the DNxHD to render instead of processing the video would be faster but if your timeline plays back at full frame rate already, then prerendering to a non-SmartRender format will not help, as you have seen.

There is really nothing Sony can do about this. They are limited by what QuickTime on Windows can do.
[Grzegorz Kwiatkowski] "Almost whole broadcast industry bases on quicktime. This is reality."
Oh, I agree. That's why I switched all of my work to Mac. Vegas is the only PC program left that I use. I do a lot of editing in FCP X now and I'm really hoping that Sony ports Vegas to the Mac like they did with Sound Forge.

John, this is not a matter of Windows. Premiere can handle Quicktime better. Avid works on Windows as well. Smartrendering Quicktime could work if Sony wanted it to.

Despite these facts I just cant give up Sony Vegas so easely (but I am thinking about it often). Why? For example.. Have you seen how slow is Adobe Premiere timeline? The playback also seems to be less fluid. Vegas lacks of many features.. but I have an impression it is basing on slim but the fastest, most tricky code in NLE industry. Sony guys must change the way they think and add more features.

Are you saying that Premiere can smart render Quicktime? I guess Sony could write their own Quicktime support but then they'd have to maintain it as Quicktime changes. It would be nice if they supported Quicktime 64-bit or even AVC/H264 in a Quicktime container so I agree it could be better than it is.
[Grzegorz Kwiatkowski] "Have you seen how slow is Adobe Premiere timeline?"
No, I haven't but I could never use Premiere for more than 15 minutes without getting frustrated with it and closing it. I have it as part of Creative Suite 6. It takes several steps to do the simplest of tasks that are one step in Vegas. I would never use it.
