Movavi Split Movie for Mac OS X is an entire editing studio in a single program. Split, trim, and cut movies in AVI, MKV, MP4, WMV, MPEG-TS (MTS), MOV, FLV, MPEG, H.264, and other formats. Unlike other Mac editing programs, Split Movie processes multimedia without re-encoding and post-conversion which preserves the original quality and lets you cut movies on your Mac up to 20x faster!
Mark the best parts and separate them out
Use the "Select" and "Deselect" buttons to mark the scenes you want to keep or trash depending on your perspective. Play the video, hold "Deselect" and remove the footage while real-time playback. To restore the trashed materials, use the "Select" button. Join selected parts of your video together or remove the unwanted ones with a single click.

Split selected scenes and merge them together
Thanks to multiple kinds of marker, Movavi's video splitter for Mac enables you to edit footage in the way that's best suited to your project. To split a large file into two parts, move the cursor to the desired separation point and click the "scissors" button. To select multiple scenes, specify the starting and ending points of all the selected scenes so you can easily cut them out or merge them together.

Trim your movies within a few seconds
If you simply need to crop your footage at the beginning, and the end, just set the left and right borders to mark where you want the video to start and end. The program will trim the unnecessary parts and you will get the final version with no loss of quality. Use the hotkeys to cut video on your Mac even faster.

Platform: Mac OS X 10.6+
