Rendering from Vegas, what's the best way? — Page 2

Oh, Grampa Frink...**sit's in Frink's lap**...WHAT I SAID WAS: YOU JUST REPEATED WHAT I TOLD THEM.......

I have that issue on occasion, and all I do is trim off 1 frame from the end of the clip that's causing the problem.

That's basically the problem - you have a blended frame. Something else to consider with Vegas is that certain effects can appear or disappear depending on the level of detail you are using to watch the timeline (Draft/Preview/Good/Best). For example, when I was making soccer videos for my kids, I would sometimes render out fast action segments in Preview quality, because it reduced the instances of field artifacts. I put these segments back into the timeline, and then rendered out the whole video, including those segments, in Good quality (which is usually fine for most projects.)

I think you might be confused.

Although things can look different/weird depending on how low the preview quality is set at, it has nothing to do with the quality of the rendered video.

You are correct that the Preview quality is independent of rendered quality, but....you can alter the actual quality of the rendered video to any of the same four levels. When I am rendering video that is to be slowed down, either in Vegas or in 3rd party software, I will render it in Preview quality to cut down on frame/field artifacts. Go to Render a video, and click on the Custom button. Under the Project tab is the setting Video Rendering Quality to see the four settings.

TBH, I've never dealt with that tab before (barely knew it was even there).

So, for the moment, I'll shut my pie-hole.

...gonna do a few test renders, to see what I've been missing out on...if anything.

Hey, I don't mind answering questions...if it helps someone learn something new. :) 

This could be a very handy feature for you. These tabs let you handle various video and audio settings as well. For example, I've tweaked the MPEG settings here to get a large MPG file to fit onto a DVD (You get a bigger difference lowering the average bit-rate, rather than the max bit-rate.) You can also include audio with your MPEG file here. I still render the audio separately, but including the audio makes it easier to spot check syncing issues in the video before rendering to DVD. You can also review your audio and video simultaneously.

As far as I can tell, changing the rendering quality on the project tab only effects the quality of the preview window during the render.

I've used the settings on the other tabs to varying degrees, and have also rendered separately for a personal DVD project.

I never said the quality difference would be night and day. It depends on what you are encoding. Furthermore, the preview window is showing you what the video will look like at that level of quality. The problem is, you don't know what differences to look for, so the differences aren't apparent to you.

Find a scene with fast motion, and view the frame under GOOD quality, and then PREVIEW quality. GOOD quality shows the differences between the fields, sometimes resulting in a double-image (motion between the fields). The PREVIEW quality isn't as precise, so it only shows one of the fields. at 30 fps, this isn't a big deal, but when I wanted to slow down the video, the difference between fields was obvious. Therefore, I rendered this section out under PREVIEW quality, ran it through my SlowMotion program, and put the new segment back in the timeline. Later, I rendered the whole video, along with this new segment, in GOOD quality.

As you can see, there are much cleaner lines in high motion videos.
