How to Apply Green Screen (Chroma Key) Using ScreenFlow

In this video, I answer a common question asked by subscribers in my ScreenFlow course about how to apply the green screen (chroma key) effect in ScreenFlow.

Beginning at bout the 15:35 point in the video, I also include a bonus topic that shows how you can use the green screen / chroma key effect — along with simple image designs from Keynote or PowerPoint — to create a simple promo clip, intro or outro for your own videos.

Key Highlights

00:20 Why green screen isn’t always the best option

2:15 – The lighting issue

6:40 – Chroma key settings: White Clip, Tolerance, Angle

[Screenflow video] How to fix video recording errors when editing your screencast video

You may be surprised how often I have to apply the technique above in my screencasting and eLearning projects.  It’s the rare thing when I can record an extemporaneous screencast tutorial perfectly with no blemishes or touches that need to be applied in the editing stage.

In fact (again!), there’s a 3-second snippet beginning at 3:57 in the video above where I had to use exactly the technique I show in the video to cover up a blemish.

See if you can spot this in the video

Screenflow, Camtasia Studio, Camtasia for Macintosh: It’s all good

Although I used Telestream’s Screenflow (Macintosh only) to demo this technique in the video above (hmmm… come to think of it: I seem to find myself using Screenflow more and more these days…), in fact the same technique can be applied using similar features in Camtasia Studio and Camtasia Macintosh.

Can you find the video artifact?

So, take a look.  Let me know if you can tell what the issue was that caused the artifact at 3:57 that I then had to cover up using the very technique we talk about in this video.
