Let’s Get Progressive

“Progressive download” means, as soon as your viewers click to view a particular video, the video starts downloading to a hidden cache file on the users machine.

As soon as enough of the video has downloaded to provide the user with an uninterrupted viewing experience, the video begins playing (as long as it’s set to: autoplay = “true”).

With a video that is encoded at a lower bitrate than the total bandwidth of the connection between the video server and the viewer, the video will start playing within a second or two, and continue without stopping. This is obviously the goal to aspire to for most purposes.

However, you don’t want to encode video with bitrate too low either otherwise the visual quality will suffer – there will be pixelization and blockiness, especially in any areas with motion.

Fortunately, choosing a video bitrate to achieve your goal while retaining visual fidelity is no longer just a matter of luck.
