After yesterday's post, Lars Steenhoff sent us an updated, side-by-side comparison of video bitrates on the Nikon D800 at 3200 ISO with NikonHacker's new firmware. Steenhoff comments that the 64Mbps file has more noise as a result of less compression, but cleans up easily in a final file output that is cleaner with just a little noise reduction. For those interested, he has also made the original 64Mbps and 24Mpbs files downloadable on Dropbox, too.
Want to get these capabilities on your camera? Head over to NikonHacker, but beware: there's always a chance you'll brick your camera (rendering it completely useless and warranty-less). So do be careful and/or make sure you can afford to do it if something goes wrong.
