How to select a video thumbnail

Video is becoming one of the most popular content types on social media, and that's why video clips have to be worked on before they are posted.

In PromoRepublic you can schedule videos to Facebook, Linkedin, Pinterest, Twitter, Instagram Business and TikTok. We don't support video posting to Instagram personal and Google Business Profile.

In order to upload a video, find the appropriate button in the post editor form.

The uploading process might take some seconds. It is important not to close this page. You can see the status in the top left-hand corner. The green sign means you can proceed further: schedule, publish, or save the video.

You'll see the preview in a couple of seconds because the video needs to be converted on the PromoRepublic server first and then on the social platform end.Β

Once the video is converted, you'll see the Edit Video Details button. Clicking it will direct you to the video editor. In the next step, you can scroll through the ribbon and find the appropriate frame. Also, you can select a custom preview by selecting an image on your computer.

This thumbnail will be used later on in the Calendar preview and on social media when posted. If needed, it is possible to select the thumbnail image later after you schedule the post.

Note these minor nuances when preparing video content on our platform:

  • The thumbnail image cannot be selected from Post Ideas.

  • One video is allowed to be posted at a time.

  • You can't include different content types in one post (for example, a video and an image).

  • You can't edit the file name inside PromoRepublic, so change the video title before uploading it.

  • When re-posting a video post, the video itself won't be re-published, but only the text, if any. So, you'll need to re-upload the file.

Video posts may fail to be published. In most cases, the problem is related to inappropriate video parameters, such as:

  1. Duration

  2. Video bitrate

  3. Aspect ratio

Let's review the video requirements of the social platforms' API. Please note that video requirements may be different for native direct posting and via a third-party service like PromoRepublic.
