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.

[ScreenFlow] Replace that screencast voiceover without losing video sync

At the DevLearn conference last week, I attended one of the breakout sessions titled, Adding Screencasting to Your eLearning Tookit. Speaker Mike Baron, Chief Storyteller at ProjectStory.com, delivered a great session with a wealth of actionable tips ranging from software equipment and budget considerations to techniques for working with subject matter experts (SMEs) and rapid content authoring sourced from SMEs.

Mike recognized me and was kind enough to give a shout-out for the blog while also kindly allowing me to chime in with my two cents during the Q&A. (Mike’s pretty cool. ‘Hope you get a chance to meet him one day.)

Q&A – How to replace audio narration with new voiceover.

One of the questions we fielded related to replacing audio narration with a new voiceover — but to also be able to do so without losing the synchronization between the new voiceover and the original video.

The answer (the subject of the video above) was right up my alley since it comes up quite frequently on projects where I repurpose product demos or recorded SME meetings for quick turnarounds as video “how to” tutorials or marketing demos.

As I was giving my verbal answer in the session’s Q&A, I described my technique of using the caption feature in ScreenFlow and Camtasia as a transcript. Doing it this way helps a lot in guaranteeing that the spoken word for the new voiceover will stay in sync with the video timing of the original narration.

Check out the video above.  If you have any questions or suggestions, I hope you’ll share ’em in the comment box below.

One of the questions I want to highlight this week from our courses‘ member only Q&A group is this one on the right about replicating moderately complex animations in Camtasia (or ScreenFlow).  That is, beyond the conventional voiceover screencasts that we see a lot on YouTube.

The quick answer is yes.  You can do much of this in any of the “Big 3” screencasting software/editors.

The longer answer:  Here’s the gist of it in the video below.

A word about third-party plugins for custom text and video animations

I’m admittedly not aware of any third party vendors that support special effects plugins for Camtasia or ScreenFlow — at least not in the way that, say, Noise Industries’ FXFactory installs itself into, say, Final Cut Pro, Motion or Premiere.   Having something like that available would be a HUGE assist in juicing-up the visual quality of your screencasting projects.

I put the question to the Techsmithies (Camtasia) and the Telestream folks (ScreenFlow) and I’ll report back here with their response.   But, I can say that there are a host of third-party suppliers of pre-keyed video and motion graphics clips that provide their media as importable media clips.  A couple you might want to check out include:  Flowtility and Marketing Motion Graphics.

If you have some favorite third-party media vendors, please share them in the comments below.
