There's also the rather more tricky problem of aliasing, which I should probably talk about in a separate article given the amount of mailbag the subject generates.

Now, the 50D is a significantly imperfect video camera, lacking any form of audio handling - there is no microphone - although this may be a non-issue on productions using dual system sound (though there is, of course, also no timecode provision). Moving on a few years, we're taking a thing which is not a video camera and making it into one using free software. Back in the day, we were lucky to hack our PAL Hi8 camcorders to record video input. Let's just take a moment to consider this. One of the last Canon DSLRs to be released before the video-capable models emerged, the enterprising software engineers working on the Magic Lantern firmware add-on quickly discovered that it does, in fact, have pretty much all the hardware of the more recent models, and with firmware changes can be made to record video. Just like anyone who bought Bitcoins about a year ago, anybody who bought an EOS-50D has arguably found themselves in possession of a deal of the century. And now people are making accessories for it! But thanks to the almost unbelievable ingenuity of the Magic Lantern wizards, it does, and does it well.
