Broadcast work with the Canon5DmkII

[Deleted User]

Just an FYI:

Much of the apparent “detail” in the “HD” video produced by cams such as the 5DM2, 7D, 1DM4, GH1, etc. _is_ aliasing. Much of what looks like real detail in their video is actually false detail — visual information created by the way these cams create 2K video frames from 12MP+ sensors using binning techniques.

Many people don’t notice most of the fake detail most of the time — PT Barnum lives! — but it’s important for video professionals to know it’s there. And it can bite you in the butt if you’re not careful. But (pun intended), you can’t make the aliasing “go away”. You can only avoid scenes which trigger it, or adjust focus, exposure, filtration, wardrobe, props, sets, lighting, etc, to minimize it — or soften problem areas of the frame in post (ick).

DSLR “HD” video resolution is only slightly better than pro-quality standard definition video or poor-quality 720p HD video.

This can be OK for many relatively lo-fi delivery media (e.g.: DVD, small-size web videos, etc.), but will be problematic for most broadcast (or post) or higher end distribution depending on what final look is desired.

You don’t have shoot test charts to prove this, you can see in real world subjects, too. But charts don’t lie. Multiple testers are reporting approx. 600-700 lines of real resolution in “HD” video recorded by the popular DSLRs.

For much, much more information about this topic, I highly recommend this must-read article by Barry Green:

I’m not bashing DSLR video. I’m actually looking forward to buying a GH1 soon. But I’m glad Barry & others are testing these cams thoroughly so we can know better what to expect out of them.

YMMV.
