Magic Lantern Raw Video In: RAW SHOOTING CAMERAS Posted July 7, 2017 · Report reply 10 hours ago, Andrew Reid said: 3072 x 1308 is 95.5MB to the card with 14bit lossless. What card are you using that gives you such a high sustained data rate? I thought it maxed out at around 85MB/s on the 5D3? Just ran a full test. Filled the card with 3072x1308 24fps... ISO100… not much movement. Data rate is 82MB/s... Stayed in the green throughout. Will test some more difficult shots later. See if it crashes.
