Create working MXF OP1a files

“

- MXF stands for media exchange format and it's one of these so called wrappers that's designed to deliver video files in a package that can be widely read and is currently being used in a lot of broadcast scenarios. So OP1a is operational pattern 1a and it's a subset inside of that MXF container, that again is the specification being used frequently these days for broadcast delivery. So let's take a look at how we create these files inside Adobe Media Encoder. So here I am in Adobe Media Encoder and I have a test file. And you can see that this was previously set to DNXHD and that that also says \MXF OP1a. So that means that these DNX files are delivered in the MXF OP1a wrapper. However, there's another choice in format which is just MXF OP1a. So you might ask, well what's the difference? And this is one of these places where Adobe is trying to be helpful but they're a little bit mixing oranges of apples or something of that sort, because the truth is that this is the same package, MXF OP1a and there's different codecs available that we'll look at in a second. But there's so many choices available in the DNXHR formats, that it made its own format, just to hold all of those choices in preset and so the list doesn't get too long. So what we really have is MXF OP1a for the non-DNXHR settings and then we have a separate format for MXF OP1a and all of the DNXHR settings. So let's look at that the other one. And what you find here are a bunch of alternate codecs that can be put inside of the MXF OP1a wrapper. And there's a lot of them. And rarely are you going to need to make an independent choice here, because what you're going to do is get the parameters from your broadcaster and for the most part, they probably are not accepting all or many of these. They're probably limited to one or several that are based around the format that they choose and then selecting exactly what your resolution is. And frequently resolution in frame rate will match what you've already been editing at. And what you're really doing here is putting this in the right codec in the right wrapper. So what you're going to do here is find the flavor that's designated by your broadcaster and if necessary, match the resolution and the frame rate to the file you're exporting. Sometimes you'll have to match if they're only accepting certain frame rates and yours doesn't match, you might have to make an adjustment here, but hopefully everything matches beginning to end. So that's a look at how you create MXF OP1a file wrappers with different codecs inside for broadcast delivery. Remember, the big key here is to get the information from the broadcaster and match that information on your export.
