If you want to try out Mevo's graphics overlays before purchasing a subscription, you can include overlays with a Demo watermark to familiarize yourself with how they work.
You will need a Vimeo Basic plan in order to access the GFX demo. Go to vimeo.com and click Join Free to create an account. The demo will not work with Vimeo Plus, Pro, and Business plans.
In the live edit view, tap the graphics overlay icon in the lower right corner.
The screen shown below will open. Tap Try it with Watermarks at the bottom to proceed.
The only difference between using them in this mode and paying for them is there will be "Demo" watermarks on all of your overlays unless you pay for a plan.
