Under Compress, change the option to Better Quality.

The best option is to choose Custom and drag the slider all the way to the right (66 Mbps in our example). However, if your source material wasn’t shot with something with a high bitrate, exporting to ProRes won’t magically make your footage better.

The absolute highest quality video codec will be ProRes. Now we have additional options for Quality.

The options you see will depend on your project’s resolution.

Tweak the Resolution and Quality until the file size is less than 500 MB In order to reduce this to under 500 MB you need to adjust the Resolution and Quality (2).
