Re: What is the difference between the Zena HS and LH cards other than analog i/o?

The differences between the two cards is certainly not just a simple licensing issue. The LH allows for saving and working with multiple formats at capture, this is specific to the needs of visual effects artists and motion graphics artists who are working with shots. The footage can be captured directly into a cineon sequence for example and used uncompressed.

The HS card used with premiere and only be used to capture with adobes HD codec and is for use with premiere for editing.

Depending on your needs each card has it's strengths.
