With certain materials, the GetWidth of the IBlackmagicRawClip and the IBlackmagicRawProcessedImage return slightly different values, is this the expected behavior?

I uploaded a sample clip to OneDrive. This was shot with Pocket Cinema Camera 6K.!AkBuNGUZGk-tiWDPEVb ... G?e=t8J2yK

With this, IBlackmagicRawClip::GetWidth returns 2868, but IBlackmagicRawProcessedImage::GetWidth returns 2864.

Hi, in this case the P6K camera is incorrectly writing 2868 into metadata. The SDK corrects it in IBlackmagicRawProcessedImage::GetWidth but ideally the camera should write the correct value in the first place (or the SDK handle it the same in both places).

Both issues need to be addressed on our side but for now the correct value is 2864 from IBlackmagicRawProcessedImage::GetWidth if you can use that.

Thank you for the reply. I'll check if we can use IBlackmagicRawProcessedImage::GetWidth instead of IBlackmagicRawClip::GetWidth.
By the way, both methods return 2868 in SDK v1.5.

Will this be fixed for BRAW API 2.0 official release ?
