Exporting Final Cut Pro project

Here are the steps:

Select the Project and have it in the Timeline.

Click the Share/Export button (square box with arrow out) as shown to reveal the Export options available:

Select Export File

Now configure the SETTINGS as shown:

The ACTION: Save Only is the most important to direct the export to a USB stick.

The Resolution setting can be adjusted to taste/limit of equipment used to playback the export.

Click the NEXT button (bottom right)

This will now show a WHERE field:

You will need to navigate to your specific USB stick, it may be called NoName unless you typed in a name.

Mine is called ALZUSB3

Click Save and wait until finished.

Use Command-9 if you wish to see the Progress Bar or this button:

Be aware of the caveats that Tom mentioned.

I'd suggest making sure the format of the USB stick is ExFat before starting the process.

ExFat works with most modern TVs, phones iPads etc.

Older gear if more specific (read the user manual)

Why do you want to put it on a thumb drive? To plug it directly into a TV? In case you need to find out exactly what format and codec the TV accepts. Also, how big is the thumb drive, and how long is the project? Short projects will probably fit without trouble on most thumb drives; a longer project might not.
