Chad Whisnant tweets in and asks, “What bitrate do you export with?”
@cineblur What bitrate do you export with?
— Chad Whisnant (@VideoWiz19) April 15, 2013
When exporting, you usually refer to the bitrate of the video in Megabits per second. Don’t get Megabits confused with Megabytes. They are not the same thing. Megabits, or Mb (lowercase b), are used when referring to transfer speeds. Megabytes, or MB (capital B), are used for file sizes.
These setting are what I use when exporting for web streaming. When exporting a 720p video, I use 5 Mbps. When exporting a 1080p video, I use 10 Mbps.
I find that using the “auto” bitrate feature takes longer to export and creates larger file sizes with more compression. So, using auto bitrate is an all-around bad idea.
Simple. If you stick to those guidelines when exporting for web stream such as Vimeo or Youtube, your video will look great while still maintaining a small file size. Keep in mind, if you are exporting for broadcast or other outlets, your bitrate will vary. Always ask them what their preferred settings are.
