保存到本地只需要在设置里找到离线设置，然后保存到文件夹就可以。具体操作如下：
1、首先，打开哔哩哔哩手机客户端，在左上角找到账号头像，点击进入。
/iknow-pic.cdn.bcebos.com/7e3e6709c93d70cf52dad873f7dcd100baa12baf"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/7e3e6709c93d70cf52dad873f7dcd100baa12baf?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/7e3e6709c93d70cf52dad873f7dcd100baa12baf"/>
2、然后，我们会在打开的菜单列表的左下角找到设置选项，点击进入。
/iknow-pic.cdn.bcebos.com/8435e5dde71190ef4292e0a1c11b9d16fdfa6066"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/8435e5dde71190ef4292e0a1c11b9d16fdfa6066?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/8435e5dde71190ef4292e0a1c11b9d16fdfa6066"/>
3、进入设置界面之后，需要找到离线设置，点击进入。
/iknow-pic.cdn.bcebos.com/a50f4bfbfbedab649da63fbef836afc378311ef3"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/a50f4bfbfbedab649da63fbef836afc378311ef3?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/a50f4bfbfbedab649da63fbef836afc378311ef3"/>
4、接着，在离线设置界面中可以找到一个主储存的选项，它就是目前所有缓存视频的去处。
/iknow-pic.cdn.bcebos.com/3b87e950352ac65c1ab8140df4f2b21193138a0a"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/3b87e950352ac65c1ab8140df4f2b21193138a0a?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/3b87e950352ac65c1ab8140df4f2b21193138a0a"/>
5、只需要跟着下面的路径找到对应文件夹，就可以把视频保存了。
/iknow-pic.cdn.bcebos.com/314e251f95cad1c8c4128e59703e6709c93d5126"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/314e251f95cad1c8c4128e59703e6709c93d5126?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/314e251f95cad1c8c4128e59703e6709c93d5126"/>
注意事项：
保存的时候，注意要选择好位置，否则会找不到。
