To create an optimal MMS video follow the steps below:

  1. First, use the animated image format photo below and to choose whether you would like to create a portrait, square, or landscape animated image.

  2. Once you've decided on the video size, use the animated image specifications table below to discover what dimensions you need to create your desired animated image. For example, to create a square video, use the dimensions, 1080px x 1080px.

  3. Then, use the safe zone specification table to make sure your important information won't be cropped when your subscribers receive the video.

  4. Once the image is created, make sure the file format is .MP4 (h264/aac) and less than 20MB.

  5. Test your video before sending it to your list.

It's important to note that on the iPhone when a static image is delivered, it's shown to the recipient in preview mode. This mode "previews" the video and as a result, crops the image. It's because of this that we recommend that you don't put any "content of interest" in the top, bottom, and side areas as specified above.

Video FAQ's:

What happens if we exceed file size or limitation?

If you exceed the file size or time limitations above, we may be forced to send your fallback SMS message, with a link to the video, which can be watched in a subscriber's mobile browser. Please always test your video before sending it to your list.

What's the max video size?

Max video size is 20MB, and Tatango will use it's transcoding engine to reduce the file size down to be accepted by wireless carriers.

Why is the file size limited?

Tatango is limited in video file size by the carriers, and each carrier is different, which means the longer the video, the lower the quality potentially since we have to apply more compression. The more movement in the video will lower the quality since it requires a higher bitrate and thus higher file size in less time.

What FPS do you recommend?

We recommend using 30 fps with ~ 2-5Mbps bitrate.

What video length do you recommend?

Speaking & low motion - we recommend under 30 seconds or less.

Music & fast motion - we recommend under 20 seconds or less.
