1、首先打開PR軟件後，在開始的界面選擇新建項目，設置項目名稱與保存位置來創建壹個新的空白PR剪輯項目。
/iknow-pic.cdn.bcebos.com/bf096b63f6246b603a298426e4f81a4c510fa2b8"target="_blank"title=""class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/bf096b63f6246b603a298426e4f81a4c510fa2b8?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="/bf096b63f6246b603a298426e4f81a4c510fa2b8"/>
2、再選擇文件菜單中的打開命令，彈出打開窗口，選擇壹個比較大的視頻文件導入到PR中。
/iknow-pic.cdn.bcebos.com/3ac79f3df8dcd1000ba7ce737d8b4710b9122fac"target="_blank"title=""class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/3ac79f3df8dcd1000ba7ce737d8b4710b9122fac?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="/3ac79f3df8dcd1000ba7ce737d8b4710b9122fac"/>
3、選中導入的大文件視頻素材，拖到時間軸窗口單擊，然後播放時間軸，由於當前這個視頻文件過大在播放的時候就會比較卡頓。
/iknow-pic.cdn.bcebos.com/b21c8701a18b87d624069d4d080828381f30fd1f"target="_blank"title=""class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/b21c8701a18b87d624069d4d080828381f30fd1f?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="/b21c8701a18b87d624069d4d080828381f30fd1f"/>
4、接著在預覽播放窗口的下方找到“選擇回放分辨率”，默認為“完整”。
/iknow-pic.cdn.bcebos.com/359b033b5bb5c9ea509c35b1da39b6003af3b370"target="_blank"title=""class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/359b033b5bb5c9ea509c35b1da39b6003af3b370?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="/359b033b5bb5c9ea509c35b1da39b6003af3b370"/>
5、單擊”完整“，在彈出的選項中選擇比較小的分辨率，如“1/4”。
/iknow-pic.cdn.bcebos.com/6609c93d70cf3bc7316ffbbede00baa1cd112a70"target="_blank"title=""class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/6609c93d70cf3bc7316ffbbede00baa1cd112a70?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="/6609c93d70cf3bc7316ffbbede00baa1cd112a70"/>
6、回放分辨率切換後，即可解決“監視器畫面特別卡”的問題。
/iknow-pic.cdn.bcebos.com/562c11dfa9ec8a137aee60b2f803918fa1ecc0ef"target="_blank"title=""class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/562c11dfa9ec8a137aee60b2f803918fa1ecc0ef?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="/562c11dfa9ec8a137aee60b2f803918fa1ecc0ef"/>
