Stay under budget and make your producers happy.
Don’t make your viewers wait.
Too often, in the blind quest for quality, people encode movies at far too high a bitrate, making viewers wait needlessly before being able to watch the movie uninterrupted, not to mention the extra strain on the server.
Or, people encode at an unnecessarily low rate, sacrificing quality when their server and viewers could handle a higher rate.
The Bitrate Budget Calculator uses a sophisticated modeling algorithm that takes five factors into account to help you determine what your movie’s bitrate limit should be based on your particular situation.
As you play with any of the five sliders, the recommended bitrate budget number updates dynamically! I don’t know any other software tool, at any price, that offers this. — Allan Tepper, ProVideo Coalition
The Bitrate Calculator is a useful, foolproof way to calculate the applicable bitrate for encodes.- MacUser UK review
What factors determine your Bandwidth Budget?
Viewer connection speed
Maximum expected simultaneous viewers
Maximum acceptable wait time
Average movie length
Let’s get progressive.
“Progressive download” means, as soon as your viewers click to view a particular movie, the movie starts downloading to a hidden cache file on the users machine.
As soon as enough of the movie has downloaded to provide the user with an uninterrupted viewing experience, the movie begins playing (as long as it’s set to: autoplay = “true”).
With a movie that is encoded at a lower bitrate than the total bandwidth of the connection between the movie server and the viewer, the movie will start playing within a second or two, and continue without stopping. This is obviously the goal to aspire to for most purposes.
The Bitrate Budget Calculator will help you determine what that magic formula is for your server, movies and viewers.
