But the genius that is Tramm Hudson has hit back with a new version for 5DmkII firmware 2.0.8 which has all the previous ML trimmings but now gives us <a href=\"http:\/\/philipbloom.net2010\/06\/11\/3rd-party-firmware-transforms-wimpy-gh1-into-optimus-prime\/\">&#8220;GH13&#8221;<\/a> style upped bit rates<\/p>\n<p>This simply gives us better compression rates well less compression really. Obviously fast cards are needed and the video buffer clearly cannot cope with the high ones but it&#8217;s going to be fun to see how far the camera can be pushed&#8230;I know from tests that have been done the hight bit rates don&#8217;t like a lot of movement in the frame either so a fair bit of work still to be done but it&#8217;s a great start.<\/p>\n<p>Personally though the bit rate has never been the issue with the Canons, it&#8217;s the line skipping which causes the moire and aliasing. Increasing the bit rate is not going to fix this. This is a far more fundamental issue with the camera and I cannot see a firmware update fixing this. A new way of sampling the sensor is needed&#8230;for the GH1 it was different the 17mbp\/s was simply too low. AVCHD 24mb\/s is superb and of course the higher ones with the hack are even better. We just must not get too caught up in numbers. It&#8217;s not the bit rate that makes the camera and I guarantee you just by going over 50mb\/s will not make it acceptable for full BBC HD acquisition!<\/p>\n<p>Below is what it can offer you..<\/p>\n<p><strong><em> +8\t 30p\t 7 Mbps\t Very low quality<br \/>\n-9\t 24p\t 32 Mbps<br \/>\n-10\t 24p\t 41 Mbps<br \/>\n-11\t 24p\t 51 Mbps<br \/>\n-12\t 24p\t 59 Mbps<br \/>\n-13\t 24p\t 62 Mbps<br \/>\n-14\t 24p\t 66 Mbps\t Best, sustainable in 24p mode?<br \/>\n-15\t 24p\t 68 Mbps\t 2 buffer bars<br \/>\n-16\t 24p\t 76 Mbps\t Only a few seconds<\/em><\/strong><\/p>\n<p>I have not tried this myself yet but will soon. This won&#8217;t screw with your camera&#8230;well it shouldn&#8217;t as it&#8217;s all RAM based so don&#8217;t be too scared to try it (but if you do end up with a brick then it&#8217;s not my fault!)<\/p>\n<p>Check out this video below of test bitrates and go to the <a href=\"http:\/\/magiclantern.wikia.com\/wiki\/Magic_Lantern_Firmware_Wiki\">ML wiki page here.<\/a> To be honest you cannot really tell much from this.
