Here’s the link to the forum on EOSHD.
Fingers crossed it makes its way over to the a77. Just as the hack on the GH2, any modifications to the firmware that allows bitrate and/or audio controls will make for a much better movie making camera. The alpha line records at a maximum 28mbps in AVCHD 2.0 codec which delivers fairly decent video but lacks detail and resolution. The hack may not help that, but 28mbps AVCHD can break up in post. Generally the higher the bitrate the better. The hacked GH2 can deliver up to 176mbps all intra frames. They both use the same stock codec, which means the first (i) frame is the most detailed followed by b and p frames that is composed by the processor’s guess of where movement in the video will occur. This can create macro-blocking and odd artifacts in the video. As such, a hack producing a codec with all first i frames and a high bitrate is popular.
I’ve talked about how annoying Sony’s insistence on only auto gain control for audio is. The hack might open things up in that department, like it did for the Canon line of DSLR’s with the Magic Lantern hack.
There are also rumors of the new full-frame a99 Sony SLT and an update that will be released around that time for the a77.
With the NEX and RX100 topping the sales charts it’s exciting times for the Sony community!
