昨天在找免費的剪輯軟體...shotcut是比較好用的，
還有openshot，可是它優化好像太爛了，照理說我的電腦不應該這麼LAG才是，
所以後來就改用shotcut了，介面簡潔也符合我需求，大家有需要可以用用看。
shotcut is a useful free video editor software. Its interface is simple and clean. It's good to use.
I used openshot another free software ,too. But the optimization is not very good. very lag and crashed sometimes.
So I think shotcut is better than openshot. You can try it.
