VUYA

May 15, 2013 4:12 PM

Thank you for having you replay.

 

I'm going to make AE Plug-In to work on Premiere pro.

I find at the SDK_Noise sample(AE SDK sample), I renewed a part of the "Render" function as follows

and carried it out.

 

but,

in the case of "src ①", noise_param.u.ld.data is "ARGB" format,

in the case of "src ②", noise_param.u.ld.data is "VUYA" format.

 

why are formats different "src ①" and "src ②" ?

 

****************************************************************

static PF_Err

Render (

          PF_InData                    *in_dataP,

          PF_OutData                    *out_data,

          PF_ParamDef                    *params[],

          PF_LayerDef                    *output )

{

・・・

     else if (destinationPixelFormat == PrPixelFormat_VUYA_4444_8u)

     {

          PF_ParamDef noise_param;

          AEFX_CLR_STRUCT(noise_param);

 

          ERR(PF_CHECKOUT_PARAM(  in_dataP,

                                                             0,

                                                             in_dataP->current_time,

                                                             in_dataP->time_step,

                                                             in_dataP->time_scale,

                                                             &noise_param));

 

          ERR(suites.Iterate8Suite1()->iterate( in_dataP,

                                                                     0,                                      

                                                                     linesL,                               

                                                                     &noise_param.u.ld,                             // src ①

                                                                     //&params[NOISE_INPUT]->u.ld,         // src ②

                                                                     NULL,                                

                                                                     (void*)&niP,                       

                                                                     FilterImageVUYA_8u,        

                                                                     output));

 

          ERR(PF_CHECKIN_PARAM(in_dataP, &noise_param));

・・・

}

    it is all dependant on the source footage format.

    It cannot be understood.

    What do you mean?

    Will I understand that this phenomenon is right if I confirm what?

    Source files are different:

    eg:     DV, MPEG2, MPEG4 is compressed YUV420 -> Converted in Importer to YUVA4444 -> PrPixelFormat_YUVA_4444_8u

              MotionJPEG is compressed RGB -> Converted in Importer to BGRA4444 -> PrPixelFormat_BGRA_4444_8u

              Apple ProRes 10bit YUV422 -> PrPixelFormat_YUVA_4444_32f

     

    In your plugin register supported PrPixelFormat_* of what you can process.

    eg: If you only process PrPixelFormat_YUVA_4444_32f register only that PrPixelFormat.

     

    version<CS5.0 you MUST support PrPixelFormat_BGRA_8u

     

    version>CS6.0 Premiere Pro will convert to your format.

     

    I recommend you make your plugin using PrPixelFormat_YUVA_4444_32f only.

    Thank you for having you replay.

     

    I use version CS5.5.

     

    I supported PrPixelFormat_VUYA_4444_32f in "PF_Cmd_GLOBAL_SETUP".

    ********************************************************************** **********************************

    (*pixelFormatSuite->AddSupportedPixelFormat)(in_dataP->effect_ref, PrPixelFormat_VUYA_4444_32f);

    ********************************************************************** **********************************

     

    Therefore, I was able to acquire a format of "PrPixelFormat_VUYA_4444_32f" by using GetPixelFormat function in the "Render" function.

     

    However,  In the Render function,

    A feild of current time("???.u.Id.data") whitch I acquired using PF_CHECKOUT_PARAM function is different from params[0]->u.ld.data.


    Why do two data not accord?

     

    [ Two data comparisons (visual studio 2008)]

    Hi U ch,

     

    Have you confirmed that the pixel formats of the two buffers are different using pixelFormatSuite->GetPixelFormat()?

     

    Thanks,

     

    Zac

    Hi Zac,

     

    > Have you confirmed that the pixel formats of the two buffers are different using pixelFormatSuite->GetPixelFormat()?

    Yes.

     

    ｢ params[0]->u.ld.data　」 is "PrPixelFormat_VUYA_4444_32f",

    ｢ "???.u.Id.data" 」 is "PrPixelFormat_ARGB_4444_8u".

      #  ｢ "???.u.Id.data" 」is A feild of current time whitch I acquired using PF_CHECKOUT_PARAM function.

     

    I have to get at the data that has been formatted to "PrPixelFormat_VUYA_4444_32f"

    to the pixel format of a feild whitch I acquired using PF_CHECKOUT_PARAM is, How do I?

     

    Thanks.

    Ah yes, so in CS5.5 and earlier, frames retrieved from Premiere Pro using PF_CHECKOUT_PARAM() are always 8-bit ARGB.

     

    New in CS6,  you can optionally specify that PF_CHECKOUT_PARAM() should pass back frames in the same pixel format being requested by the current render.  In the AE CS6 SDK, in PrSDKAESupport.h, PF_UtilitySuite4 contains EffectWantsCheckedOutFramesToMatchRenderPixelFormat().  Your effect should make this call during PF_Cmd_GLOBAL_SETUP, which is the same selector where an effect would already advertise support beyond 8-bit RGB using AddSupportedPixelFormat().  After making that call, the two frames in your example above will be VUYA_32f.

     

    Cheers,

     

    Zac

    I understand.

     

    Can you convert it from ARGB to VUYA (from VUYA to ARGB)?

     

    I want to do Next.

    1. I convert from ARGB to VUYA.

    2. I apply special effect for VUYA.

    3. I convert from VUYA to ARGB.

    4. I copy ARGB to "output".

     

     

    Please teach a method to convert.

    The PPro SDK has some sample code for you to start with.  See the ConvertFromBGRA32fToVUYA32f() in SDK_File.cpp.  You'll need to modify this to handle ARGB rather than BGRA_32f.  And you'll need to do the reverse function to get back to ARGB.
