More Magic Lantern magic – the video “zoom” feature

by planetMitch2 Comments

A few days ago we posted the story about “Magic Lantern adds 3x multiplier (zoom) to RAW video for the Canon EOS 5D Mark III” after discovering that the new RAW video module could also do a virtual lens zoom for your video – essentially changing the sensor ‘crop factor' by extracting smaller sections of the video from the sensor.

This seems to have slipped by most people who are justifiably excited about the RAW video capabilities. But let's not forget the Nikon D800 has several different crop modes – so this is even more capable as it turns out you can do different crops with the Canon EOS 5D Mark III.

Huge south swell in this weekend! 6-8 feet with occasional larger sets. What a beautiful day in Hawaii!!! 🙂

Here's a similar video with no zoom (but 2 extenders) [tentblogger-vimeo 66496506]

Magic Lantern rocks!

Frankly, after reading thru some of the posts on the forums, I'm still confused about exactly what crop factors (zoom factors) are available, but they're still working on Magic Lantern features so we'll have to wait to see how it all falls out.

Either way, this is yet another amazing feature of Magic Lantern! What do you think? Sound off!
