Hi, this is Gary with MacMost.com. Let me show you how to export a
portion of a larger video as a separate file on your Mac.

So let's say you have a long video. Now if you want to use that in an iMovie or Final Cut Pro
project the problem is bringing in that large video makes the project huge. But if all you want
is a small clip from that large video it pays to export that clip first to a separate file and then
just use that small clip in the project. Now if you try to do this using iMovie or Final Cut Pro
it kind of defeats the purpose. You have to create this big project just to export this small clip.
But you can do it using the simple Quick Time Player that's on your Mac.
This will allow you to open the video, export just a portion of
it without ever creating some big other project or file in between.
As an example let's take this ten minute video here, which is an old film. Let's say we just
want a portion of this. So, in Quick Time Player there's some editing tools. There are two ways to
approach this. First let's just use trim. I'll go to Edit and then Trim, or Command T. This brings
up this special interface here at the bottom. Now I can select just the part that I want.
When I get to that one part I can click Trim. Now I can go to File, Save.
It's not going to save over the existing video but instead ask to save something new.
So I can call this Clip 1 and save it to the Desktop. Notice how fast it does that. It's not
exporting the video. It's actually just taking that clip and putting it in a separate file. So
it's not reprocessing everything. So now I've got these two files here. This first one is 238 MB and
you could see it is almost ten minutes long. This small clip that I exported, this one is only 17 MB
and it's just 38 seconds long. So now I can bring this small clip into the iMovie project
and keep the iMovie project relatively tight without bringing in this huge 200 MB file.
In many cases it could be a lot worse than that.
Shooting a long 4K video on your iPhone can give you a file that is several gigabytes in size.
If you just want a portion of that you can use this technique to have a small file.
Bring that into iMovie instead of increasing your iMovie project size by those several gigabytes.
Now when you exported the clip and maybe you want to export another clip all you
need to do is use Undo. Just Command Z. Then you're back to the original video.
Then you can do Command T again and trim to export another section.
Another thing I want to point out is if you want precision, notice how you don't get too
much precision here because the entire video is in this really short timeline here. But if you
have a trackpad and you click and then you force click, just click even harder, it actually zooms
in and now you have great precision over exactly where to put the Start or the End of the trim.
Now there's another method you could use as well that might work better in some situations. Instead
of going to Trim use the Split Clip Function. So first let's go somewhere in the middle here.
It might be easier to navigate around, play the video, and get exactly where you want to start.
Although if you're going to be using this in another editor, like iMovie or Final Cut,
it pays to get a little bit extra at the beginning and at the end especially if you're not sure the
exact parts of the clip that you want or you might want to add transitions. So you go a little bit
before. But let's say I want to start here. I could do Edit and then Split Clip or simply
Command Y. This goes into a very similar looking interface here. But you can see the two parts. Now
you don't have to stop here before you export. You can grab this red line and drag it somewhere else
and do a split right there. Continue to do it and breakout just the parts that you need. Maybe
some of these pieces you need. Like maybe I need this one. I don't need this but I do need this.
Now you can go in and Delete the parts that you don't want. So I'm going to use the Command
key to select all the part that I don't want. Leave that part. Then I'm going to hit Delete.
Now I just have this portion here. Now I can go and Save and let's call this Clip
2. You can see it appear here. Now I simple Undo and it brings all those parts back.
So now I could use the Command key and click Reselect That Part, Deselect This Part,
Delete. Now I just have that section. Now I can Save and call this Clip 3. Then once again Undo.
Now whether you're using the Trim method or you're using this method you can simply close
this. The original is not going to change. If I go back to the original now you could see
it's still ten minutes long. It doesn't have those sections at all. If I go into Split
again or Trim again you could see it's kind of starting fresh there. So this isn't going to
effect the original. But if you go to close this it will ask you if you want to Save this. But
you see it says Export As. So, no, of course, you don't want to save what's left over here.
Just press Delete and you have your original video right there. Then you have your small clips right
here ready to use in your editing software without having to ever bring in this big heavy long video.
That's just a sample of what you can do using the editing tools of Quick Time Player. It's ideal for
doing things like trimming video, exporting clips like this, or even rearranging clips inside of the
video. You can do that easily without ever having to use iMovie, Final Cut Pro, or something else.
Hope you found this useful. Thanks for watching.
