Using transparent PNG files is a great way to make call outs or watermarks for your screencast videos. It’s a pretty common question that comes up all the times on screencasting boards and Twitter.
Use this technique if you want to add creativity to your screencasts. It’s perfect for call out’s and visual reminders. It’s also a great solution for adding a watermark for protection or branding.
This screencast shows how easy it is to add a transparent png file to your project.
I’ve had several people ask me which tools I use to create my transparent .pngs. I use Pixelmator and you can find it in Apple’s App Store.
