    Unfortunately that isn't going to be an option.

      It not only won't happen it CAN'T happen.

      The G400 for the RT-2000 has specially tweaked filtering and other changes necessary for Flex3D.

        Girgory,

        Try to answer your questions:

        1. Is it possible to feed RT2000 with two DV streams via two firewire inputs , make effect and output analog video stream, all in realtime?

        NO! Only one DV input is supported at one time. Chip can decode two DV streams simultaneously

        2. Is it possible to make the card read two DV streams from PC drive(s), do transition and output analog in realtime? System requirements?
        Absolutely. This is called real-time effects. Of course you need to have both in Premiere, define effect and play. You get stream on analogue in RT.

        3. Is it possible a)to make the card read two DV streams, either from drive or from firewire, b)make G400 accelerated transitions and produce mpeg2 stream, all in realtime or X*realtime? c)What is X value?
        No! The system works in DV OR MPEG. One project can have only one type of data.

        4. Is it possible to feed one DV and one mpeg2 stream and still use realtime transitions, realtime or near realtime?
        No! See above.

        Pity you cannot mix and match DV and MPEG but you will need to go to much more expensive (and probaby vapourware) system than this (e.g. FAST Blue ??).

          Andrew,

          Thanks for the very good info.

          1. So, RT2000 can use only DV or only MPEG2.

          2. Mpeg2 hardware accelerated compression is blocked when I render two DV streams, because the hardware codec is busy with DV. Am I correct in this point? Note, I am not saying "realtime", but only "hardware acceleration".

          3. Last clarification - if I make DV movie, and then start to compress it to mpeg2, is this process accelerated, or mpeg2 HW ENcoder will still be blocked by DV DEcoder? (remember - you said only DV or only MPEG at a time)

          4. What can I do to get 1-5 x realtime DV to mpeg2 conversion? Finally, can RT2000 do this?

            To quote Matrox,

            "RT2000 creates an MPEG-2 AVI file (with an IBP GOP structure as required for DVD authoring and distribution application) from MPEG-2 I-frame or DV projects in two to three times realtime regardless of the number of effects they contain."

              Hi Grigory,

              1) Yes, the RT2000 can "only" use native DV or MPEG2 during editing.

              2) MPEG2 isn't "blocked", you choose which compression scheme to use when you start a project. If you are capturing DV input, then you use DV throughout, with the option of rendering to an MPEG2 file as a final product. If you are capturing analogue input, you can decide whether to use DV or MPEG-2. Obviously if you want to mix both analogue and digital footage you will have to choose DV as the project format.

              3) DV to MPEG-2 conversion is hardware accelerated.

              4) Sorry, I thought I made this clear in the preview : "Creating an MPEG2 output file takes between 2 and 3 times realtime, regardless of effects. "

                Chris,

                Thanks for clarification.

                I was little bit surprised to see contradictory point like:
                "One project can have only one type of data." in Andrew's post.

                So, I had to ask again.

                  Hi Grigory,

                  No problem. This stuff is all so new that there are too many pieces to the jigsaw. I've manages to assemble most of the edges, but who knows what lurks in the middle !
