1、打开制作视频的源文件，我使用的是EDIUS制作软件
/iknow-pic.cdn.bcebos.com/a686c9177f3e67092d9abb1535c79f3df9dc5546"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/a686c9177f3e67092d9abb1535c79f3df9dc5546?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="
https://iknow-pic.cdn.bcebos.com/a686c9177f3e67092d9abb1535c79f3df9dc5546"/>
2、找到相对应的字幕文件，并双击打开
/iknow-pic.cdn.bcebos.com/34fae6cd7b899e510331c4fe4ca7d933c9950d98"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/34fae6cd7b899e510331c4fe4ca7d933c9950d98?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="
https://iknow-pic.cdn.bcebos.com/34fae6cd7b899e510331c4fe4ca7d933c9950d98"/>
3、利用文字工具进行文字的修改，同时还要调整字间距，不要让文字超出了安全区域
/iknow-pic.cdn.bcebos.com/32fa828ba61ea8d324718aee990a304e241f588d"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/32fa828ba61ea8d324718aee990a304e241f588d?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="
https://iknow-pic.cdn.bcebos.com/32fa828ba61ea8d324718aee990a304e241f588d"/>
4、然后对字幕文件进行修改的保存
/iknow-pic.cdn.bcebos.com/dbb44aed2e738bd48b9f4cdbaf8b87d6267ff99a"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/dbb44aed2e738bd48b9f4cdbaf8b87d6267ff99a?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="
https://iknow-pic.cdn.bcebos.com/dbb44aed2e738bd48b9f4cdbaf8b87d6267ff99a"/>
5、然后接下来就是视频的输出格式的选择，最好选择和原视频一样的格式。
/iknow-pic.cdn.bcebos.com/b90e7bec54e736d187ad72e295504fc2d462699a"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/b90e7bec54e736d187ad72e295504fc2d462699a?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="
https://iknow-pic.cdn.bcebos.com/b90e7bec54e736d187ad72e295504fc2d462699a"/>
6、最简单的一步就是找到要修改的视频，进行覆盖输出
/iknow-pic.cdn.bcebos.com/7a899e510fb30f244c2312e9c695d143ac4b039a"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/7a899e510fb30f244c2312e9c695d143ac4b039a?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="
https://iknow-pic.cdn.bcebos.com/7a899e510fb30f244c2312e9c695d143ac4b039a"/>
