a test i did today:
http://dl.dropbox.com/s/p1qo960nrhmcd7g/crop_vs_non_crop.webm1. 18mm raw video crop mode (no sharpening, some saturation added)
2. 55mm raw video non crop mode (no sharpening, some saturation added), @handbanana: that's why i said, that non crop mode is just not usable
3. 55mm h.264 auto picture style
4. 18mm h.264 video crop mode auto picture style
5. same as 1. but with a lot sharpening
6. same as 3. with the same sharpening as 5.
7. same as 1. with noise reduction, additional saturation and a lot of sharpening
i should have added 3 more pixels to the letterbox at top and bottom to cut the distorted rows. -.-
what the video imho shows:
- h.264 crop mode is bit softer than h.264 but still usable and of course there is much less aliasing
- crop mode raw video on eos m looks really great... less aliasing than h.264 non crop mode and flat image that has imho a very cinematic look out of the box.
- again, raw non crop mode imho isn't usable!!
- h.264 also doesn't has perfect edges (if that lowers the expectations what you should get out of the raw)
- you can add a lot more sharpening to the raw video than to the h.264 in post, without overdoing it and getting to bad sharpening artifacts. this also leads to a sharper overall result.
EDIT:
something totally went wrong with my export from yesterday. hadn't really checked it after export and expected it to be nearly the same i saw in the editor. but as i watched the exported video today i saw that the quality was much worse, because the editing software exported 24i instead of 24p.
i did a fresh export and updated the link...
