There’s now a handy tool in the Video Editor which enables you to speed up the video preview. This is very useful, especially for longer videos or videos with complex editing, to reduce the amount of time you spend reviewing each video when making edits.
Use the slider control below the Play/Pause button on the left side of the timeline to increase speed up to 2x. Speed up and return to normal speed at any part of the video preview to make your work most productive. The tool is available now in the Video Editor so give it a try!
