I was browsing around to answer some questions I had and was reading the Amazon.com’s temporary page for the Zune HD when something in the disclaimer caught my eye:
Specifically shown in the image is that the Zune HD will support 5.1 channel (or surround sound) output, although since this text is immediately beside a completely incorrect reference that the Zune HD will also support 1080p (which it won’t), I took it all with a bit of salt and moved on.
…Until a minute ago when I was playing around with the newly-released Expression Encoder 3 trial (since I was curious about what I’m missing) and found a Zune HD-specific profile that basically tells me all the specs I need to know about what the device will handle:
The profile in question is for the Zune HD AV Dock Playback, which is vastly different from the vanilla Zune HD profile, as it has proper 1280×720 output (versus the screen-specific 480×272) and an immensely higher bitrate of 6.1Mbps/12Mbps (average/peak) compared to 1Mbps/1.5Mbps. And on the audio front we’re going from 128Kbps on the vanilla profile to 384Kbps for the AV Dock profile. The sample rate and bits for both are 48KHz and 24-bit…
So the Zune HD will handle both the video and audio excellently, which is all especially useful to know since I’d probably rather save some money and make a profile for the free (but somewhat reliable) Windows Media Encoder.
