I've done some more extensive testing with the tool over the past couple of weeks, regrading the opening scene of the first Matrix film Blu-ray to match the PAL DVD. I know spoRv attempted this a while back, but comparing his to mine revealed that DrDre's tool is far more accurate.
First 6 minutes of the film here:
This was a shot-by-shot regrade too. There are some problems with crushed whites, which the tool doesn't handle well as we know, but overall is looks almost exactly like the DVD.
Just a couple of things I thought I'd mention with regards to the tool itself as well. Firstly, it'd be good to have an Abort button somewhere. At the moment if you make a mistake and want to cancel the calculation or conversion, you have to use task manager to shut the program down and then reopen it.
Secondly, I don't know if this is just on my PC, but there were a number of occasions where I'd be building a correction model, and then for no apparent reason the tool would just stop calculating mid-way. The progress bar would hang and my CPU usage would drop to idle. If I recropped the images and tried again it would usually work but not always.
In any case, as I said before it's an awesome program.
