如何将字幕ass文件和avi.视频文件合在一起

1、首先需要将视频文件和ass字幕文件放在同一个文件夹里，如图所示；
/iknow-pic.cdn.bcebos.com/d50735fae6cd7b89714de9e6002442a7d9330eb6"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/d50735fae6cd7b89714de9e6002442a7d9330eb6?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/d50735fae6cd7b89714de9e6002442a7d9330eb6"/>
2、然后需要将ass字幕文件和视频修改为相同命名，如图所示，字幕文件和视频文件都为相同命名；
/iknow-pic.cdn.bcebos.com/ae51f3deb48f8c5434dd144a35292df5e0fe7f4d"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/ae51f3deb48f8c5434dd144a35292df5e0fe7f4d?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/ae51f3deb48f8c5434dd144a35292df5e0fe7f4d"/>
3、然后在QQ影音中打开该视频，可以看到当视频和字幕放在同一文件夹时，在QQ影音中打开视频就会自动加载字幕了；
/iknow-pic.cdn.bcebos.com/38dbb6fd5266d016e1364d4d982bd40735fa35ac"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/38dbb6fd5266d016e1364d4d982bd40735fa35ac?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/38dbb6fd5266d016e1364d4d982bd40735fa35ac"/>
4、如果直接打开视频没有自动加载字幕，右键点击播放界面，然后选择字幕——载入字幕；
/iknow-pic.cdn.bcebos.com/42a98226cffc1e1786e45f544590f603738de978"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/42a98226cffc1e1786e45f544590f603738de978?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/42a98226cffc1e1786e45f544590f603738de978"/>

5、然后，我们找到刚才电脑本地文件夹中的ass字幕文件，选中该字幕，然后点击打开即可；
/iknow-pic.cdn.bcebos.com/b3fb43166d224f4a6693a27606f790529822d149"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/b3fb43166d224f4a6693a27606f790529822d149?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/b3fb43166d224f4a6693a27606f790529822d149"/>
6、这样就可以成功加载字幕了。

方案一:软字幕，用mkvtoolnix封装
方案二:硬字幕，通过avisynth的vsfilter滤镜加载字幕，然后送去压制。
ps:不管怎样，你都需要台电脑。

可以用mkvtoolnix软件添加视频和字幕文件然后重新封装。
