Thank you for the detailed feedback.

1) The new compression rate control algorithm is doing for the best it can, but is still a tad flakly, as can crash the encoder. I get this crash maybe once or twice on a 5" reel. But like you see, I think the result are worth it.

2) I still what to make the manual white balance user settable. I need to work out how to sense button presses. This is not hard to change, if it is always too blue.

3) Manual exposure is still a work in progress, but it really depends on the source reel. I'm looking for way to enable or disable it, without a firmware change.

4) Currently they are not setting any flag for video range. But it should be fixable in firmware, I just haven't found it yet. They have to wrong data in the VUI (Video Usability Information) stored within the 'avcC' mp4 box in the headers. So it is fixable.

As for the random framing change, I've seen that too. It is not very common. My crude shutdown seems to sometime fake button presses.

Can you post good before and after images? I would love to see more users of these enhancements.
Great work on the firmware adjustments. I have an m127 machine which appears to be much the same as the kodak etc but runs different firmware. I managed to take a dump of it but have struggled to get a bootable image flashed back. As you seem rather skilled with messing with firmware I don't suppose you can take a look, perhaps you cans shed some light? I'm having to flash the rom back with a chip programmer currently as I can't seem to make anything flashable with the ntk tools (it's a dual partition image unlike the kodak and other models it seems).

This my first time a firmware hacking, and I starting with a working firmware update procedure. Without the stock firmware update step, I wouldn't have gotten anywhere. Sorry, I have no idea about the firmware partitioning.
