Render one clip from multiple veg, or join mp4's without recoding

Parser wrote on 6/11/2023, 6:24 PM

I have a project with multiple video tracks, lots of short clips etc. To make my GUI work faster and manageable, I split the project into parts, each about 15 min long. When I'm done, is there a way in Vegas to render one clip from multiple project files, so that, for parts 2 and later, their zero point is exactly at the end of the last clip in the previous project? I don't want to manually assemble the whole project in the GUI and render it as a whole, if I can avoid it. I could render individual parts in Vegas, then join them, but I don't want to re-code all video. Is there maybe a software that can join several mp4 files into one, without recoding? (Vegas Pro 20, Win 10)

@Parser

In a new Vegas Pro project, drag all of your individual projects (Project 1.veg, Project 2.veg, ...) on to the new project timeline (nesting).
Render the new project.

Thanks, I'll try that. When "nesting" I don't deal with project contents, each project is just a "unit", yes?

@Parser

You can think of the “nested” project contents as the same as a rendered video when it’s on the master project timeline.

Easier, much faster and also without recoding is to MERGE seamless the individual rendered mp4's with the (free)tool Shutterencoder, the Swiss Knife for every Video editor.

Thanks, I'll give Shutterencoder a try when I get to joining my sub-projects. Have you personally joined mp4 with Shutterencoder? Is the splice point seamless?

@Parser Looks fine. I tried joining a standard video file to it'self that had a common file structure output from an NLE Auto GOP 250. The original file begins with a GOP of 99, with it's final GOP being 142, when it is joined using the merge command in Shutter Encoder, the first GOP of first file remains 99, the end of first file still ends in GOP of 142, and beginning of 2nd file (now joined) starts with GOP of 99 and ends with GOP of 142. The GOP's are not corrupted.

I've also uploaded these joined files to YT before, with some joiners weirdess happens with YT at the join position, but it behaves as expected using Shutter Encoder and YT encodes the joined files without problem.

I use(d) it for merging all my rendered (sub)projects. Merging is only one feature of the dozens of features Shutterencoder has. As said, Shutterencoder is the Swiss Knife for every Video editor. I use it almost daily, besides Vegas.

You can also concatenate video files with ffmpeg.

Shutter does more than concatenate. It properly terminates dangling GOPs, an important consideration in nonlinear editing.
