LiveEdu 视频录制与上传注意事项

我们的内部转换器无法识别某些视频格式,这会带来一些不便,因此请您确保在录制好试录片段后就向我们上传视频,在细节设置方面,请遵循本指南进行如下调整:

  1. 请确保以 FullHD (1080p) 格式保存视频,如果您只能以 HD (720p) 格式录制视频,也请在其余部分采用与下列相同的设置:
  2. 视频比特率:4000 Kb/s — 8000 Kb/s(我们的内部转换器会将其转换为 2500 Kb/s;为避免质量损失,最好在录制之初就设定一个较高的比特率)。
  3. 视频编解码器:H.264
  4. 音频编解码器:AAC 128-192 Kb/s (也会在内部被转换):
  5. 请确保在上传视频之前将不需要的片段剪辑掉,您可以使用一些免费的后期工具,譬如 LightWorks 
  6. FFMpeg 转换器支持大多数知名格式:mp4、avi、mkv (matroska),但我们需要坚持使用 mp4,因为它是最具兼容性的格式。

如果您还没有视频转换器软件,我们推荐您尝试曦力视频转换器

它的 UI 很简练,您可以用它来十分方便地以 “Youtube_1080p” 预设格式来预编码和剪辑视频,而这一格式兼容大部分场景。

或者您可以使用狸窝视频转换器:http://www.leawo.cn/

但是,如果您使用该软件或其它自己选择的软件来进行渲染,请确保其细节设置与上述相同。

当您完成视频的转换工作之后,下一步就是上传并分享给您的项目经理。您可以访问咱们的官方视频上传平台。点击 “Select files” 选中您需要上传的视频,然后再点击 “Upload” 进行上传即可。完成上传后,请告知您的项目经理以加快审核进度。

上线您的视频可能需要花几天时间。请确保将您想要上传视频的项目设为 active(进行中)。 否则这些视频将会被添加到您当前的 active(进行中)项目里。当您的视频正在被处理的同时 – 您可以做一些其它的事来提高效率,譬如开始录制新的项目,这样,在您的第一个项目的视频上线的同时,您就可以着手上传第二个项目的视频了!

如果您更青睐于直播项目,而不是录制视频,请将您的直播设置为 full HD (1920×1080) 格式或 HD 格式(取决于您屏幕的分辨率)、增大音量并将比特率设置为 1600 以避免在直播过程中出现潜在的延迟。在您即将首次进行直播时,请提前 2 天告知我们,这样我们就能把您加进官网上的直播时间表中,项目经理也会与您安排一次试播,以确保您在细节设置上一切 OK。

如果您有任何问题,可以直接向与您相对应的项目经理提问(使用 Slack、QQ 或微信联系)。我们祝您在创建项目的过程中一切顺利!
