When I used regular Gordian Knot... I often set my resolution to the max possible without distortorting aspect ratio (usually 704 width), ran the compressibility test, then set the bitrate so that the compressability was around 75%. How about a new mode for AutoGK that does this?
Right now AutoGK adjusts the resolution in order to make it compressible, or if the width is fixed, just encodes with a low compressability rate in order to make the target file size. If I do 1-pass quality based, I find that 75% based on codec's level of quality is still a higher file size than 75% compressability (at the same resolution).
I think having a quality based mode that takes the results of the compressability test gives the best of both worlds.... it maximizes quality while make the most efficient use of the codec....
What do you think?
