I have exported the same video twice, but with the number of mbits/s reduced in the second (from 2.8 to 1.1).
The size of the export is drastically reduced, from 71 Mo to 28 Mo, but I cannot see any obvious change in quality. What does the amount of mbits/s change? Is it then worthwhile to export all my videos with the amount of mbits/s reduced? Thanks!

Bitrate is the amount of data in a video or audio signal measured in bits per second. Generally speaking, higher bitrates produce better quality video and audio, while lower bitrates create media that is easier to play back over slow Internet connections.
The bitrate (data rate) affects the quality of a video clip and the audience that can download the file given their bandwidth constraints.
When you deliver video using the Internet, produce files using lower bitrates. Users with fast Internet connections can view the files with little or no delay, but users with poor connections must wait for files to download. Make short video clips to keep the download times within acceptable limits if you think a majority of users may not have good internet speeds.
