我的節目:序列1那邊預覽的畫面只有左上方能看到，剩下1/4部分都白的，但輸出時畫面也正常，在看項目、素材欄位那格也碰到一樣問題，左上1/4看的到，剩下3/4都跑不出來，重調參數與習慣方式、重新安裝與開機後仍有一樣問題。

Hi ​@北方熊熊小菊花  are you experiencing this issue in Premiere desktop or mobile? If desktop this should be moved to https://community.adobe.com/p/premiere

Thanks!

​@北方熊熊小菊花,

A screenshot might help. I wonder if  you have gotten into multicam mode (Program Monitor, wrench icon).
