Join Jeff I. Greenberg for an in-depth discussion in this video Transcoding to ProRes, part of Compressor 4.1 Essential Training.
It's really powerful and useful to take Compressor and turn it into a compression station for transcoding. Transcoding is technically what we're doing the entire time. I tend to call transcoding making a file big or keeping it large, where encoding is making a file small. There are a bunch of Apple ProRes settings here directly that I can drag and drop from. But I want to show you how you can make one for yourself. So instead of just doing the drag and drop and walk away, I'm actually going to build my own setting, by going here to the bottom, and choosing the little plus, and saying New Setting.
Immediately I'll get a pop-up menu of what I want to do. And in this case I want to build a QuickTime movie. I'm going to call this my Custom ProRes Preset, let's make this a ProRes LT. There are five types of ProRes we're going to see those all in a minute, and I'll give you some general ideas of what they do. The Light version is a smaller than ProRes 422. It's used a lot by news where they want to keep the bandwidth down a little bit in their internal communications at a news facility.
I'm going to choose OK, here we've got my preset and I'm just going to go over here to the Video tab. Now, I'm modifying the preset, not the one that's actually applied. There's currently nothing applied to this current shot. When we're done we'll apply it. I'm actually modifying the RAW preset. I'm going to go up to the Video tab here. And all the magic of getting to the rest of QuickTime is by clicking on this QuickTime settings box where it says Change. And you can see the default right now is ProRes 422. There's an earlier movie about data rates, small data rates, and large data rates, spelled small files and large files.
ProRes has preset data rates, there's nothing we change there. All we can choose is what flavor of ProRes. I'm going to go ahead here and pick my QuickTime settings, where I'll get a QuickTime dialogue box. This allows me to get to everything existing inside of my computer's install. So, when I go ahead and click this menu, we see other compression types here. Understand that this has to do with what's installed on my machine. What's installed on your machine may be different, but I guarantee you ProRes is on your machine. There are five different types of ProRes, starting with Proxy being the smallest, Final Cut will build these approximate files, these tiny files.
They're fine for editing as long as you remember to switch back to your original footage. Or to higher quality footage. We have the light which will be the end product. This is a lighter version of ProRes 422, proxy's about 35 megabits per second, LT's 100, ProRes 422 is 140. You can hear as these numbers get bigger the end file will get bigger. ProRes 422 is approximately 220 megabits per second. It's great if you're coming from a format such as like Red or uncompressed, and you would like to compress your video a little bit, but still keep a decent quality.
And ProRes four by four also contains an alpha channel. This is great if you're building graphics say from something like Compressor. This will automatically keep the transparency information. Since, what we are trying to do is build a gorgeous file that's just a little bit smaller. I am going to choose LT, which I would not normally use except in certain workflow, such as news. With this selected, I am going to say OK here, and I have got a Custom ProRes Preset. I think it's, we are now at a point where we ought to really rename that. So, again, with this selected in my settings, I'm going to go to the General tab, and I'm going to give it a little bit more information.
I'm going to call this ProRes LT, our News Workflow. And with that being done, I can now reuse this over and over again as a drag and drop to any of my specific work.
