Feature Focus: New JPEG 2000 Bitrate Controls

Now available in the Premiere Pro (Beta) builds is the addition of bitrate controls for your JPEG 2000 MXF OP1a exports.  


Shipping VersionShipping Version

In the currently shipping version of the export settings for JPEG 2000 MXF OP1a the bitrate was generically set based on the Broadcast Profile and Tiling options you selected. Unfortunately the lack of manual bitrate control would often lead to higher-than-expected bitrates in the final output.

Now you will see that we have prioritized the bitrate settings over the somewhat less useful Broadcast Profile setting. In doing so we have also tweaked a few other options: 

  • Previously JPEG 2000 output was only Lossless if you selected a specific Broadcast Profile. Now this is a user-selectable option.
  • The Bitrate Slider does from 10Kbps to 100Gbps though if the maximum bitrate is set higher than the amount of data the encoder produces at maximum quality, the resulting bitstream will have a lower bitrate than the value shown in the UI.
  • Updated the max frame size limit from 4096 x 3112 to 16K x 16K
  • The Broadcast Profile is selected automatically based on the settings you've chosen but you can still override the setting if necessary. We've also added support for Broadcast Profiles 8-11 as well as level 0. 
  • Removed the tiling option - it is now configured automatically. 


Also, to make the changes as seamless as possible, your existing presets should automatically utilize the new settings. 


Give the new settings a try and let us know what you think!
