premiere pro sdk rendering to PrPixelFormat_VUYA_4444_16u

Hi, I had tried to use exporterUtilitySuite->DoMultiPassExportLoop to render video to PrPixelFormat_VUYA_4444_16u format. But the output raw video is only partial rendered as shown in the image.

I had also tried to import the video with same format, but premiere pro cannot replay it and  shows black frame instead. The import video is valid and playable with YUView with VUYA 4444 16bit interlaced.

So the question is that, is the rendering for this format is not working for premiere pro at the moment? In my understanding ,this format should be packed as [[V0, U0, Y0, A0] [V1,U1,Y1,A1] ...] each plane is in uint16_t. Is it different for PrPixelFormat_VUYA_4444_16u  format?

Thanks
