Project Settings Best/Good creates duplicate frames?

[D. Eric franks]

I’m not certain what the render end of things does, but I do know that in the Preview window, there’s often a big difference between Preview mode and Best (Full) mode, especially where it concerns deinterlacing and (as I suspect in your case) conforming different frame rates to the output. So, just for example, if you are using 60i source in a 24p project, any issues you might have might not reveal themselves until you pop the Preview window up to Best (Full). Another way to see where you might have problems is to zoom in to the frame level, where you’ll see that the frame markers on your clip do not match up with the frames on your timeline. Not necessarily a problem (indeed it’s usually not a problem, since Vegas handles this conversion automatically), but the app does need to make a decision about where the last frame in a 60i clip is on a 24p timeline and it may be a frame before or after where you want it! You can also see this when you drag your clips around: sometimes they won’t want to butt up against each other and will either leave a gap or a one-frame crossfade.

I always render out Best and check out my projects at Best (Full) in the Preview window in the final stages, just before encoding.

Hmm, I really want to get to the bottom of this, my project framerate and video framerate were the same.

Here’s what’s going on [I took screen shots of Best/Preview in the preview window]

Best / Good [Full]

Preview Full

note: It doesnt matter if its full/half or anything it does the same thing, and when I render with Best/Good it causes that frame tween effect you see on the first shot, but only on fast motion shots usally

Here’s the properties box of project settings and the clip

I recorded the clip with Fraps at 29.970FPS progressive, right now its zooming out kind of fast. [it seems to only happen on fast motion, maybe it’s trying to add a motion blur?]

I’ve had this problem on DVD ripped footage also, so it’s not confined to this game clip.

This is what is in the Vegas manual under render settings:

Choose a setting from the drop-down list to set the quality of the rendered video.
Unless you have specific performance problems, choose Good. Choosing Best can dramatically increase rendering times.
Good uses bilinear scaling without integration, while Best uses bicubic scaling with integration. If you’re using high-resolution stills (or video) that will be scaled down to the final output size, choosing Best can prevent artifacts.

I’m not sure if it’s suppose to do that to your footage, but I’ve taken already filmed footage before from a movie to play around with in Vegas and when rendering on best it altered big time from the original source, all of the fast parts had that frame tween effect you seen.

This has been keeping me from rendering everything at Best/Good for a long time, I’ve always used Preview and I really don’t notice any degrade in the video between Preview and the Original. I wish they could list what Preview does in the Vegas manual as opposed to Best/Good

Anyone got any idea? Still confused about this :S
