Summary

There are two ways to share videos to your social accounts through Buffer Publish. The first way is to upload your video within the Composer and the second way is to share a link to the video. This guide provides an overview of how videos will appear and behave on each social network.

Video upload requirements

Buffer Publish currently supports videos up to 1GB in the file formats of mp4, mov, or avi. The video you upload will be converted to MP4 encoded with H264, and a maximum resolution of 1280 x 720 pixels (HD). Larger files are likely to be compressed to ensure they can be posted to the social network, but quality loss should be minimal. Unfortunately, we can't support Apple ProRes or raw camera formats like ARRI and RED at this time.

Why is my video taking a while to upload?

When a video file is uploaded, there are a few steps the file needs to go through, including checking the file to ensure it can be passed over through the API, having AWS (Amazon Web Services) transcode the file, and generating potential thumbnails. When generating thumbnails, we look for a different thumbnail every 15 seconds. This means that for a video that is 30 minutes long, we would try to generate at least 120 different images. This can be a key factor that affects the upload speed.

Depending on the file size, the length of the video, and the connection speed, each of these things could take different lengths of time and determine how long the overall process takes. If you are uploading a short video and it is taking a long time, please get in touch and we'd be happy to troubleshoot!

Custom thumbnails and titles

Choosing a custom thumbnail and title for your video

Once your video has finished uploading, click the small pencil icon at the bottom left of the video to adjust the title and choose a thumbnail. Thumbnails are generated at 15 second intervals of the video. By default, the first frame of the video (0 seconds) will be used as the thumbnail.

Choosing a thumbnail for your Instagram video works a little differently. Once your video has finished uploading, click Edit Cover. From there, drag the slider to the position in the video you'd like to use as the cover image and then click Save cover.

The option to choose a cover for your Instagram video is only available on our Pro and Business Plans. It is not available on the Free Plan. More information on our plans can be found here.

How thumbnails and titles are used on each social network

Since videos appear and behave a little differently on each social network, the thumbnail and title you choose will only be used in certain places.

Facebook
Videos on Facebook play automatically, which means thumbnails are redundant. Therefore, any custom thumbnail you choose will be ignored. However, the title you enter will be displayed at the top of the video post.
Instagram
Videos on Instagram play automatically on the home screen feed, which means thumbnails are redundant in that location. Therefore, any custom thumbnail you choose will not be displayed there. However, the custom thumbnail will be used as the cover of your video on your Instagram profile.
Twitter
Videos that are within Twitter's permitted file limits (512MB and up to 140 seconds long) play automatically, which means thumbnails are redundant. Therefore, any custom thumbnail you choose will be ignored. However, videos that are outside of Twitter's permitted file limits, are displayed as a link to Buffer's video player and the custom thumbnail, as well as the title, will be shown.
LinkedIn
At this time, Buffer Publish does not support native video uploads for LinkedIn, and therefore, any videos uploaded will be displayed as a link to Buffer's video player. The custom thumbnail you choose will be used as the cover image for the video, and the title will be displayed beneath it.
Pinterest
Videos on Pinterest will be displayed as an image, using the custom thumbnail you choose. The title will also be shown at the bottom of the video if users visit the video page.

Facebook

Video upload

Videos appear natively and play automatically once published to Facebook.

Video link

Your Facebook post will include a link attachment. Users are able to click on the video link and will be taken to the video in a new browser tab.

Instagram

Video upload

Videos appear natively and play automatically on the home screen feed once published to Instagram. On your profile, the custom thumbnail you've chosen will be shown, and users can tap on it to play the video.

One thing to be aware of is that Instagram's permitted video length is between 3 and 60 seconds. If your video is not within this range when you upload it to the Composer, you'll see a message letting you know. You'll need to adjust the video and then re-upload it.

Please note, videos being shared to an Instagram Personal Account will be scheduled as Reminders, whereas videos being shared to an Instagram Business Profile will be published automatically (assuming they're within Instagram's accepted aspect ratio range).

Video link

Instagram do not currently support hyperlinks within captions. Therefore, if you include a link to a video within the Composer, it will not be hyperlinked once published. Instead, it would be published as plain text. Users could copy and paste the link from the caption to a new browser window, which would take them to the video. However, this method is not commonly used and instead, we would recommend using the upload option described above.

Twitter

Video upload

Videos appear natively and play automatically once published to Twitter, if they are within Twitter’s permitted file limits of 512MB and up to 140 seconds long.

Please note, an mp4 file that only contains audio cannot be shared to Twitter. The mp4 file must contain video. If you are looking to share an audio file to Twitter, the best alternative would be to host the audio file elsewhere online and link to it (instead of uploading it within the Composer). Twitter would then generate an audio Twitter Card from the link.

Videos that are longer than Twitter’s threshold will be displayed as a link to Buffer's video player. Users are able to click on the video link and it will be played within the Tweet (i.e. as opposed to opening in a new tab or window).

Video link

Your Tweet will be displayed as a video post. Users are able to click on the video link and it will be played within the Tweet itself (i.e. as opposed to opening in a new tab or window).

LinkedIn

Video upload

At this time, Buffer Publish does not support native video uploads for LinkedIn, and therefore, any videos uploaded will be displayed as a link to Buffer's video player. The custom thumbnail you've chosen will be used as the cover image for the video, and the title will be displayed beneath it. Users are able to click on the video link and will be taken to the video in a new browser tab.

Video link

Your post will include a link attachment, and the video will play automatically within the post itself.

Pinterest

Video upload

Videos will be displayed as an image, using the custom thumbnail you've chosen. A link to Buffer's video player will be generated and added to the description of the Pin. Users could then copy and paste the link from the description to a new browser window, which would take them to the video. This method is not commonly used and instead, we would recommend using the video link option described below.

Video link

When scheduling a post for Pinterest, you're required to upload either an image or a video. Therefore, after dropping the link into the Composer, you'll still need to choose or upload an image to accompany it. Once published, the video will be displayed as an image link and users can click on the image to open the video.

Tip: Add the video link to the Source field, rather than the body of the post, if you don't want the link to be displayed within the description.
