Thank you for the response, but where is that command. I do not see it.

I have a sub-clip in a longer video of many separate elements. I wish to extract that particular sub-clip and render it so that I can use then import it to replace the original much bigger file from which the sub-clip was taken to reduce my storage size for the project. Of course, I can do this by editing the bigger file separately, but I am looking for a direct path to create the video file of the selected sub-clip.

File - Render As.

If you don't render a new file, a "sub-clip" will always reference the original file.

I am not understanding your response. I created a new project, imported a "master" video. Created 2 subclips. Put these on the timeline. Rendered the file. When I deleted the master video, this also deleted the subclips as they were still linked.

If I select a single subclip of the two on the timeline and then do file - render, it renders the entire timeline.

Not sure what you are trying to do. If you want to render a portion of the timeline you need to make a selection and render only that region. If you then import that rendered video into VEGAS it won't be related to the subclip or master video, it is its own video.

I build videos that often have 50 or more individual video elements. Often, the clips used are from much larger videos--several GB. I would like to be able to take a clip from the timeline--often a subclip of the longer video inserted onto the timeline--and save just that portion being used as a separate video. I would then replace the original longer video with the shortened part that I am using, enabling me to then remove the longer original video from the project. Then, when the project is saved with the media, it does not have the longer GB videos. With the use of fades, selecting just a selected "loop" doesn't work as it would include the fades.

It appears that this is simply not an option.

If you don't intend to delete the longer video, consider nesting as a way to work with short pieces of video in your master project. I'll resist the urge to show you how it's done.

If your intention is to save a minimal set of media for your project, there is a variation of "Save As" that automatically trims your source media to the sizes of the events on the timeline. Those files are then saved in the same place as the place you choose for the saved project.

There is a "Copy media with project" checkbox in the "Save As" dialog. From "help":

If you selected the Copy media with project check box, a dialog is displayed to allow you to specify how you want to copy media files: ...

See help for "Save As".

@James-Snead Hi, no you can't just save individual parts of a video. Either render the clips separately or nest them as suggested -

Import your video to the timeline & -

Render

• Make a loop region selection, right click the blue bar loop region & render the loop regions individually to a new track, this will create individual clips in your windows folder. (it'd be nice if this had an option to render to the track above instead of always creating new tracks)
• Render the Loop region using File - Render as, this will also create individual clips in your windows folder, you'll have to do this individually with each loop region. (Markers can be placed to mark the loop regions & it'd be nice if Render as had the option to render these out individually in one go)

Nested

• Select the region you want, cut it (split), then nest it, this will create individual little projects in your windows folder that can be dragged/imported into another project without the need of the orig main video.

Thank you for your response. I have not used nests before.

Just tried to select a single video clip from the timeline and then select the nest button. On three separate tries, Vegas Pro 22 stopped. Tried adjoining clips. Same thing happened.

Opened Vegas Pro. Created a new project. Imported large GB video. Placed on timeline. Cropped to just a small 10 second piece. Selected nest. Asked me to save the project. Did this. It then stopped.

@James-Snead Yeah, sorry I can't really give a decent reply, nesting used to crash VP for me but with recent versions. Vp21/22.. It seems to have been stable, my media is prob smaller, UHD MP4 HEVC max 30mins-ish, It might depend on what you call 'large GB video'. How big, not that it should really matter I guess? - I just tried a 30p 5312 x 4648 8;7 .MP4 HEVC 10.74GB GoPro video without problems.

 Can you click your icon at the top of this page - My Profile & fill in your Signature with the full name of your CPU, GPU & amount of RAM, also inc the Windows & Vegas version, this will then show at the bottom of your comments, 👍

, On the forum here there was mention that it was grumpy for some but not for others,, I haven't seen or read anything recently about nesting, or at least I don't remember anything.

Thank you for your response.

Perhaps I am pushing the system. I run Windows 11 Home on a gaming laptop with an i5-10300H CPU with 32 GB ram. The video card is a NVIDIA GeForce GTX 1650 Ti with 4 GB. Vegas Pro is using the video card. I am outputting a 1920 x 1080 MAGIX AVC/AAC MP4. The input files are either 1920 or 1280.

You have a sub-clip that is part of a bigger file. That "sub-clip" will ALWAYS be a part of a bigger file. So what you have to do to eliminate that is to make a NEW file and the replace the sub-clip with that new file. Say you have this file where "s" is the "sub-clip" portion:

ffffffffffffffffffffffffssssffffffffffffffffffffffffffffff

You put the sub-clip on the timeline and you end up with:

ssss

However, it's still linked to that larger file. Now SELECT that sub-clip (or just make it the only thing on the timeline) which you can do by double-clicking it. The go to File - Render As, select something like Apple ProRes so it doesn't lose as much information and select a matching preset (will have an "=" beside it if it matches and choose loop region only if you double-clicked it and there's other things on the timeline). Render the "ssss" to a new file so now you will have much smaller file that only has "ssss". Then you can use that newer smaller file INSTEAD OF the sub-clip and it will no longer be linked to the larger original file.

In your reply above, it sounds like you DID render it out but then you still used the sub-clips instead of the newly rendered files. You have to replace the sub-clips with the new renders.

@James-Snead Hi, 1920x1080 isn't big as an input, the output doesn't really matter at the mo but the type of input file might/would affect how your PC handles it.

There's an App called MediaInfo, download it, it's free & a fast download with no added adverts or any of that rubbish, everybody on here uses it https://mediaarea.net/en/MediaInfo.
After downloading, right click on the media file in your Windows folder, open MediaInfo, choose Text from the options at the top, drag the edges of the window that pops up so it shows all the information & screen capture that page, post that image on here using the arrow button next to the smiley at the top of a new comment 👍

Or Copy & paste the information in a new comment like this -

Here is how I understand subclips - other more experienced users please correct me if I am wrong. A subclip is a shorthand way (and small file way) Vegas uses to refer to a portion of a larger file. You might think of it as a simple text file saying "from the 13 second to the 26 second mark of abcd.mp4". Much smaller than the 13 second video file in full. Provided the file and its name remains constant then this short text file can also be interpreted by Vegas either within the same project or in another project.

It's comparable to saying "paragraphs 4 to 17 of chapter 7 of abcd.xyz". Nice and short but if you delete abcd.xyz that becomes meaningless. To re-use it without the original file you would need to save the actual text of paragraphs 4 to 17. Similarly, to make a subclip reusable if you intend to delete the original file requires rendering it into a reusable video form.

Subclips can be a useful time and space saving device and I use them all the time along with nested projects, but it does require a little understanding of how they work.

I hope this has been of a little help.

Vegas always requires a render when extracting snippets of video and audio from a larger file. The effects of that reality can be eliminated or minimized by using lossless (or minimally lossy) video and audio formats. There is yet another method that works well if you don't intend to keep the large source files after you've cut out what you want to keep. There are programs that cut without reencoding. They will cut some media that have long groups of pictures to the nearest I-frame and save a smaller file to within two GOPs of the size that you want. That's usually close enough for horseshoes, hand grenades and clips that will be used in larger Vegas Pro projects. Shutter Encoder and VideoReDo TVSuite 6 are two such programs. 

Shutter Encoder

VideoReDo TVSuite 6

Personally, I find the interface of Shutter Encoder very tedious and even tried on Reddit to shame the author into buying the assets of VideoReDo from the estate of the now deceased author. The user interface of VideoReDo is quick and customizable, but the output possibilities are frozen in time by fact that it's no longer supported and available for purchase.

All that being said, I just nest and move on with life. The exception might be when I record hours and hours of the Super Bowl and use VideoReDo to cut out the halftime show. It only takes a few minutes. I usually don't even know which teams played...

... or care.

Thank you everyone for your help. This information will help me to be more efficient in future projects. For those that are interested, here is the video that I created.
