The Expression Encoder team has announced the plans for SP1 of their product (announced, not released). You can read all the details on their team blog for more information, but two things caught my attention that are probably of most interest: H.264 encoding and a Silverlight 2 template in the box.
The H.264/AAC encoding support is a result of customer feedback (as well as preparing for future Silverlight support). While the profiles in this service pack will be limited and may not meet the needs of everyone immediately, it is a great step and will probably meet the needs of most.
Byte-range seeking: When a user clicks forward on the timeline into a non-downloaded region, the player will cancel the current progressive download and start a new one from the point that has been seeked to.
Sweet. I can’t wait. The SP1 will happen by the end of the year and will be a free upgrade to existing Encoder 2 customers.
