*on EOS M / 100D it still not 100% stable, but you can record around 4 minutes and 30 seconds on average ~80 MB/s before it switch to 48 MHz (drop to 21 MB/s). I got 240 MHz working perfectly (based on my tests) on 5D3, and got 240 MHz usable to *some point on EOS M / 100D! However, if you’re impatient to give it a try, you can download it here.I have been digging into SD overclocking stuff again for few weeks, my goal was to achieve stable 240 MHz SD overclocking across all DIGIC 5 models. As I said, it still needs some improvements, and Magic Lantern team is working on fixing the bugs. If you decide to try out the latest mode, you can learn more about it on this link. When refreshing LiveView settings, the camera might lock-up (no idea why). If it happens, decrease the vertical resolution a bit. Since these settings were pushed to limit, the risk of corrupted frames is high. This is very tricky to solve, as we only get 3 full-resolution buffers in LiveView, with restrictions on the order in which they must be freed, and lots of other quirks. High-resolution modes (in particular, full-res LiveView) may cause trouble with memory management.

Ĭanon preview is broken in most modes you need to use the grayscale preview in the raw recording module.1080p45 should be a little more manageable at 111 MB/s. I’m still hunting the issues one by one, but it’s hard, as Canon’s LiveView implementation is very complex, and our understanding on how it works is still very limited. These are the possible problems you may experience when using the build: The team is working on improvements, but still advises you to test the update thoroughly before you use it for some serious work. Now, it’s worth noting that this concept is still a bit rough on the edges and there are bugs to be fixed. Full-resolution LiveView: 5796×3870 at 7.4 fps (128ms rolling shutter).The latest update allows these new resolutions to the users of the 5D Mark III:
