Vegas AVI PRE-Render

Movick wrote on 4/22/2006, 12:07 AM

Of late I've been editing ever more complex pieces, and the need to pre-render sections such as montage openings is becoming unavoidable. For whatever reason, when I pre-render a timeline section as an .AVI out of VV5, it looks discernibly poorer in quality than sections not pre-rendered after the final render. Does anyone have a clue as to why I am having this issue? I notice this difficulty predominantly where text or still images are incorporated into the pre-render. Is there any solution to get a clean pre-render which will equal the other sections of the timeline once the final render is completed?

Thanks,

Movick

"Does it matter whether the render is ï¿½finalï¿½ or ï¿½pre-renderedï¿½ for use in another timeline?"

Yes, it matters. "Pre-rendered" and "another timeline" are incompatible concepts. Pre-renders can only be used within the project that generated them. So, if you're talking about creating a file that can be used elsewhere then it must be a final render.

Pardon us for not understanding that you want to use these clips in another project. Your initial question was about pre-renders and that made me (and probably others) assume that you were creating pre-renders to use within the same project.

Rob - I have much the same workflow, work on separate scenes and segments, and render each one out for use in a later master project.

When I do this I choose Video for Windows avi and the NTSC DV template. Are you saying to click Custom and choose a different video format such as Uncompressed?

I'm oversimplifying. Movick said he was having trouble with Text and Graphics degradation. In that situation it is better to render those areas as something better than a DV AVI. DV AVI will cause tearing on the crisp edges of text, generated media, and still images (especially graphic elements).

Vegas does a great job when the DV footage is *just* dv footage. In that case it'll do a straight copy to the new DV avi file. But if there is text or graphics over the DV footage you'd get better results going uncompressed for that little bit of footage.

It pays to spend some time doing tests, just like real DPs do before they shoot a feature. Getting a better idea how the formats work allows you to make informed choices about how to render a file.

I do quite a bit of "pre-rendering" myself and use the "render to new track" command. This has typically worked well for me with comparable content (text and/or generated media over DV clips).
