Performance optimization of pre-processor using video proxy codec

A non-transitory computer-readable storage medium having stored thereon computer executable instructions, which when executed by a computing device, cause the computing device to be operable for:

• receiving source content;
• pre-processing, by a pre-processor, the source content to output pre-processed source content, wherein the pre-processor includes a first parameter that is trained based on a differentiable proxy codec, and wherein a calculated adjustment to a second parameter of the differentiable proxy codec is used to train the first parameter of the pre-processor;
• encoding the pre-processed source content into compressed pre-processed source content;
• and
• outputting the compressed pre-processed source content.

An apparatus comprising:

• one or more computer processors;
• and
• a computer-readable storage medium comprising instructions for controlling the one or more computer processors to be operable for:
• receiving source content;
• pre-processing, by a pre-processor, the source content to output pre-processed source content, wherein the pre-processor includes a first parameter that is trained based on a differentiable proxy codec, and wherein a calculated adjustment to a second parameter of the differentiable proxy codec is used to train the first parameter of the pre-processor;
• encoding the pre-processed source content into compressed pre-processed source content;
• and
• outputting the compressed pre-processed source content.
