Issues with DPX Writer with bitDepth=16i and channel='rgba'

[Prabhanjan Kumar]

Hi,

I tried to encode dpx input to dpx output with bitDepth=16i as output parameter.

When I open this output file, it looks weird. Lot of noise and encoding is not correct.

Same happend with alpha channel(rgba) also.

Does Tuttle dpxwriter supports 16bit and rgba?

Regards,

Prabhanjan.

Hello,

Indeed I tested to output a dpx image with parameter bitDepth=16i, and the image is unusable.

I need more time to investigate and understand why. For the moment, you can do this operation with an other plugin: oiiowriter.

If you are using the sam command line, you can do it this way:

sam do r input.dpx // oiiowriter output.dpx bitDepth=16i

The output image looks good to me. Is it ok for you?
