What is MP4 pseudo streaming?
The MP4 pseudo streaming option, which can be found in your resource’s Other Settings section, is referring to the ability to skip to not yet downloaded portions of an mp4 video file. Meaning, you can play the video from any point, without having to wait until it is downloaded to that point.
This is available by default, if you play the video directly in any HTML5 browser. However if you are using flash player to play these videos, this is not the case. The MP4 pseudo streaming option will fix that for you and will allow pseudo streaming even for the flash players, so your visitors can enjoy seeking in your videos freely, without any waiting times.
