Nested Clips
Make even the most complex projects more manageable. With a single click, ScreenFlow’s nested clip feature lets you merge multiple elements into a single (nested) clip whose content can be accessed and edited on a separate tabbed timeline.
Very complex sequences can be encapsulated in a nested clip, which keeps your project organized and makes it easy to create re-usable elements. Nesting also provides another form of clip grouping; you can apply video filters and actions such as speed changes, color correction, or effect filtering to a nested clip, giving you a powerful mechanism to join existing content.
Media Library organization tools
A number of improvements have been made to ScreenFlow 4 Media Library to make it easier than ever to find and organize all your clips. New features include search functionality, list view, ‘Arrange by’ controls, lasso selection, context sensitive ‘select clips in timeline’ feature, resizable library window and more.



Closed Caption support
Add closed captions to all your movies. Use ScreenFlow’s caption editor tool to add, edit and publish ADA Compliant soft subtitles as caption tracks to your MPEG-4 movies (suitable for playback with an iPhone & iPad) and YouTube videos. Preview captions by selecting “Show Captions” in the view menu. Caption tracks can be created in multiple languages and can also be exported separately as an SRT file.
MPEG-4 export
Export faster, higher quality MPEG-4 files using the x264 codec
Chroma Key
Transport yourself to a new studio or location using ScreenFlow’s high quality Chroma Key filter. Replace your green (or any color) background with your own video or still image background with a single click.
Core Image video and audio filters
Create your own style by adding video and audio effects. ScreenFlow 4 adds support for a vast array of built-in filters to add effects to videos and images, as well as audio. Video effects include advanced color adjustments, distortion effects, blurring, alpha mask, color effects, and more. Audio effects include EQ, multiband compression, peak limiting, delay and more. Each filter has parameters that can be further adjusted for fine tune control. Apply multiple filters to a single clip or also apply them to nested clips.

Dynamic Update of Media
Save time and eliminate extra steps when you refine media created outside of ScreenFlow. Videos, images and external audio imported into ScreenFlow remain linked to their original sources. If a source asset is modified, ScreenFlow will offer the option to ‘reload’ the modified asset. When reloaded, the asset will dynamically update in the library, timeline and canvas. (Not available on the Mac App Store version of ScreenFlow).
Recording timer
Need to record a webinar, and don’t want to stick around till the end? With ScreenFlow’s Recording Timer feature, now you can set the duration of time (in minutes and seconds) you want ScreenFlow to record. When the time period has elapsed, ScreenFlow will stop recording and launch the editor window.
Paste a clip into an existing gap in the timeline
Now you can choose to insert a text clip, an annotation clip or any media in your library to fill an existing gap in the timeline. No need to adjust the size of your new clip to fit the available space – this handy feature does it for you.
