Most of the Blu-ray movies in 3D have been published in a 24 frame format, so if you convert such sources to a digital stream, wouldn't keeping 24 frames, one, use less bandwidth, and two, at 24 Hz (48 Hz alternating 3D frames), be easier to support hardware-wise? I do not know if Sony has any issues with "games" running in 1080p/24 in 3D.

    Everyone seems to be stuck using the legacy 60 Hz format for streaming videos even though most movies are being correctly published in a 24 frame format. Even games might benefit from a less stringent frame rate.

    I am already a little leery of the quality loss injected into HDX compression, why add to it by converting 1080p/24 Blu-ray movies into 1080p/60 HDX streams?

    I am sure 99.99% of those who can view 3D at 1080p will be able to do so at 1080p/24. Would anyone disagree?
    Sorry, but in the end it's just a matter of the programming APIs Sony provides. An app/game can switch to 3D output and render stereoscopic 3D into two framebuffers that are output at 720p60. In that case, there is no way to do 24fps output since the PS3 always outputs 3D as 720p60 FP ("frame packed"). (Here's a reasonable explanation if you are curious... http://www.best-3dtvs.com/what-is-frame-packing-3d/)

    As an aside, most VUDU HDX movies are 1080p24 and I believe most HDX TV shows are 1080p30. I believe(?) the PS3 always converts to 1080p60 (unless in 3D as mentioned) but most decent TVs process all of these signals to whatever they can display natively doing reverse pulldown as appropriate, so in the end no information would be lost...

      This is the first thread (and link) that pops up when doing a Google search on this topic, so I figure I should ask here:

      Has this 720p limitation for 3d on the PS3 been lifted by Sony or is their API still limited in this way?

        The PS3 hardware is limited to 720P for 3D. We are working on supporting 1080P 3D on the PS4, as the hardware is capable of it and Sony recently updated their SDK to support it.

          Cool. Thanks for the update.

          Does the PS4 allow downloading like the PS3? That's important for my crappy internet connection.

            According to peoples comments on other threads there are no channels that transmit at 1080p as far as i am aware most HD is 720p apart from upscaled SD. If you have Virgin you can set up the Vbox to send 1080i to your tv.

              Only cable and OTA TV are capped at 1080i or 720p (depending on channel). Vudu HDX is 1080p unless limited by the hardware.

                  Has this been fixed for PS4?
