Convert PF_pixel data into RGB or RGBA format

[SonaliBhargav]

Hello, 

I am developing one plugin where I want to save EXR file data from Params[0]->u.ld.data into buffer as some RGB format. 

I got the values of alpha, red , green and blue as in PF_Pixel type. When I saved it in buffer the data is not matching with EXR file data. Can anyone suggest?

Why are you attempting to save an AE Effect plug-in's pixel buffer, directly to EXR? 

If the user needs .exr, they can export a project item (transcode) or sequence (encode) to EXR format.

I am using torch libraries in my plugin that is not supported by the adobe Premiere Pro software so I am trying to do this conversation. 

Could you please tell that which pixel format do we need to use in Globalsetup() to import EXR files(half) which has 3 channel RGB data??

Changing the pixel format provided by PPro will not solve your problem. 

Again: Why are you trying to import EXRs from within an effect plug-in? Using torch libraries may not be the right approach. What is the overall workflow you're trying to support? 

EXR Importer plug-ins ( not effect plug-ins), which can import EXR data, are already freely available.

Hi Bruce,

As it is confidential so I might be not disclose here .

I am trying to convert one DNN model to adobe premiere pro so for that i am trying to import OpenEXR file .

Thank you .

[Bruce Bullis]

Yes, you had said that before; that's not what I'm asking. 🙂

Could you please describe, from a PPro user's perspective, the entire workflow you're trying to support? 

If importing EXR files is the actual requirement, you could simply use these free plug-ins:

Hi, Is there a way to save EXR image data from Params[0]->u.ld (image data) into buffer as RGB or RGBA infomation. As per my understanding of the source code Params[0]->u.ld.data gives me the values of Alpha, Red, Blue and Green data as PF_Pixel type. However, when I saved it in the buffer, it is not matching with the input EXR file data (hex view). Could you please suggest me the correct sequence logic to save the data in RGB format from Adobe Premiere pro Host format.

[Bruce Bullis]

There's no sequence logic to suggest; your effect would need to do the work, to move the data from the buffers provided, into EXR compatible buffers. 

Also...why would you do this from within an effect plug-in?

If the user wants to save an .exr file, they can do so from either the Source or the Program monitor...
