Quickly generate social media reels, short videos, or tutorials with just a few clicks. Forget about manually trimming or splitting long footage. Instead, place markers by pressing the asterisk (*) key where you want to split the footage, and this tool will divide the selected layer into multiple short clips. Use the In-Out button to specify the in and out points of your clips. Alternatively, you can use the 'Lazy' button for automatic cuts with your desired clip length.
