Video: Understanding transcoding

So I did want to address one note before we launch into other parts of this course, it's half housekeeping and half logistics. As we saw when we brought in our AMA media we have instant access to work with this media. Now if you like you can work via AMA through the entire duration of the project. There is a chance that your system performance could suffer a little bit, but by and large my experience working with QuickTime AMA is a very good performance. However, sometimes it become necessary to transcode the media to Avid's native file type of MXF.

Understanding transcoding

So I did want to address one note before we launch into other parts of this course, it's half housekeeping and half logistics. As we saw when we brought in our AMA media we have instant access to work with this media. Now if you like you can work via AMA through the entire duration of the project. There is a chance that your system performance could suffer a little bit, but by and large my experience working with QuickTime AMA is a very good performance. However, sometimes it become necessary to transcode the media to Avid's native file type of MXF.

For example, for this course, I had to transcode all AMA media to a very low resolution MXF file so that I could fit everything within the limit of the exercise files. So I want to show you how to do that. So here is all of the AMA clips, at least for the interviews, and again, we have total access to this, we can work with it, look at it, edit it, name it whatever, and I can continue to do that. Here are some sub-clips based on those AMA clips, I'm just going to take a look at these, these still point to those AMA files.

You can see that they are still looking in that Footage folder and these are still basically QuickTime. So I can continue working in this way if I want to, but I want to transcode, basically you select the clips that you would like to transcode and then you right-click and choose Consolidate/Transcode and Transcode is actually going to change it into another resolution. So like I said I need to make all of the files in this project very, very low resolution so that we can fit them in the exercise files, we're basically going from 430 plus gigabytes down to 4, so a lot of compression here. I'm going to choose my Drive.

I've taken great care in making sure that I have enough handle or extra media to the left and the right of my in and out points, so I'm going to select zero here. And then in Target Video Resolution, I have all of the available HD resolutions to me, and the reason I had HD resolutions available to me and not Standard Definition is that I am still in an HD project. So in my case, because I would like to actually transcode it to standard def I'm going to need to change my project Format, which is right now at the 1080p/23.976, to just the standard definition 23.976.

So that now when I select these files and right-click and choose Consolidate/Transcode, I'll choose Transcode and drive, zero Handle length and here are my standard definition resolutions. So like I said, I really, really compressed these files, and this would not be something that you would normally do during any regular workflow in working with the documentary most likely, but what I did was I compressed most of them to a 14:1, and you also need to convert your Audio Sample Rate, you can do that on the fly during the transcode process and then I just click Transcode, okay and then basically new media files, MXF media files were created.

And as you can see, I kind of already done this as we have seen throughout the rest of this chapter, but I have everything organized and transcoded in each of these bins. So as you can see, if I kind of go through here, it's not the best resolution, but it can certainly work, as we're going through we can still see everything pretty well, we can hear everything, we can still edit our documentary, it's just we're at a either 14:1 or 28:1 resolution.

So it's up to you, leave the files linked as AMA if you like, or if you want to transcode to Avid's native file type of MXF if it makes sense in regard to your performance or your workflow.
