Quad HD samples available from JVC U.K.
 

I should have posted this information on a new thread. But, I posted it on a dormant thread. Sorry.

You can get a short sample -- 4 files -- from JVC:

JVC Professional Europe - GY-HMQ10E 4K2K HD Camcorder - JVC Professional catalogue : product details

I imported into FCP into 4 tracks and used the motion filter to move into place in a 3240x2160 ProRes 422 sequence.

For details of how to this, see my post at the end of the "other" GY-HM thread.

Attached is a screenshot of the Timeline.

Because I already expected a problem with QuadHD in FCP X, I put a circle wipe in my sample.

The problem is that FCP X does not have a QuadHD PRESET. So I used the 4096x2160 PRESET.

This leads to "issues" I'm working on.

You can see a QuadHD sample I uploaded to YouTube. To do this, I exported QuadHD H.264/AVC at 144Mbps from FCP X. (That took a bit of work because this SHOULD require AVC Profile 5.2 which isn't available.)

Yes -- you can upload 4K, but you can only view at 1080p.

Thanks to Petter for this tip:

Use clicktoflash.com plugin for Safari to block Flash.

Then hover over video to see a list of H.264 movie sizes and choose 4K.
