Under each tab you can select a default resolution. You are not locked into this resolution. Tools and dialog windows will still allow you to override this default whenever you want.

Apply to All: If you'd like to set a specific resolution and have it applied to all the different media type tabs, rather than having to do it one by one, simply click on the Apply to All button.

The benefit of breaking the media types into categories, such as Capture, Render, and Import, is that you can then set different defaults for each. For example, on a project with many hours of taped footage, you might elect to capture all of your footage at a low resolution in order to increase how much media will fit onto your drive(s). This will mean that when the project is creatively finished, you will go through a second process to recapture just the video portions that are being used at a much higher resolution, a process frequently called the Up-Res, so that the image quality will be higher. You may prefer to not have to go through a similar process for all of the titles, still images, and motion graphics, so you could elect to set the default for these media types at the level where you need them to be for the final master (for example, 1:1).

Under each tab, you can select a default location for the media types to be stored. You are not locked into this. Various tools and dialog windows will still allow you to override this default when desired.

This selection is helpful for ensuring files go where required, and it allows you to send render files (known in Avid terminology as Precompute files) to a specific drive if required by your facility.

Apply to All: If you want the storage drive to be the same for all the different media type tabs, rather than having to do it one by one, simply click on the Apply to All button.

Changing this is only possible for SD video, as HD will always be in the MXF format. Media Creation settings will default to the file format called Material Exchange Format (MXF). You should not change this unless you are in the unique situation where you are generating media on one workstation that will have to be used on a much older workstation that can only play the Open Media Framework (OMF) file format.
