Re: development towards 1080p50/60

How about over the HDMI input?

Dear Tim,

That may be possible.

HDMI can transfer that data in RT, but whatever we put out of the HDMI/SDI, I don't think any of these signal can't be recorded as MPEG-2. Those frames rates are off the specs of the MPEG-2 norm.
Beside needing a new MPEG-2 flavor, I guess we would need a new processor more than a Firmware update.

Re: development towards 1080p50/60

Dear Friends,

I should have been clearer in my reply to Tim.

Yes, I feel that 1080p60 is technically possible over HDMI.

No, the nanoFlash is not designed to handle 1080p60. For one, the Sony Codec can not handle 1080p60 as far as I know.

Re: development towards 1080p50/60

If it's possible to specify upper field or lower field first w/ 60i encoding, then there seems to be at least a hypothetical solution to this.

You could split the signal and send it to two encoders. One encoder is set to 60i upper field first. The other is set to 60i lower field first. Combining the streams coming out of these two encoders (similar to detinterlacing PsF material) could create true 60P.

Now how practical any of this is, I of course have no idea.

Re: development towards 1080p50/60

ARM Cortex or Nvidia Tegra are (IMO) two types of processors showing promise of raw encode power for 1080p60.

The problem at the moment is: The codec.

MPEG-2 cannot efficiently take in 1080p60. H.264 may be an option, but royalties could get in the way.

AVC-Ultra, the vaporware codec from Panasonic, was to be the definitive 1080p60 codec. Unfortunately, we haven't heard of any products using it.

What we need is an open source codec that encodes well for acquisition in 1080p60 and fits within mobile processor specs for encode/decode. VP8 is what I had in mind, but it's (as expected) under attack from the MPEG-LA.

nanoFlash could offer a Cineform option for 1080p60 if a partnership ever arises down the line. But that's wishful thinking.
