EOS M Magic Lantern shot in RAW: Full 720P Video

Yes, it is soft. The video resolution is a lot lower than what you'd get from the 1080p out of the camera--even the 720p. (the RAW is upscaled a bit) RAW is not inherently better than the video that will come out of the EOS-M. Indeed, for most uses, the video out of the EOS-M, as Canon intended it, will be the best quality.

RAW is all about dynamic range. RAW captures all the information from the sensor at time of shooting. You may or may not want this information. For example, when the camera is shooting native video it is looking at colors and brightness and making quick executive decisions. It might decide about a point in an image, that will look better as a black, and that will look better as a red. Usually it does.

With RAW, you might decide that what would look better as a black would be better as a gray, and what came out as a red is more like a brown--because that's the mood you want. That's what RAW gives you, in post. You can get some very subtle, film looks in your video. It's a matter of taste. I love the film, high dynamic range look. Not for everything, but for some things.

RAW to me is just about having more choice with what I want to shoot. If I"m shooting a party outside I'm going to shoot regular video. If I'm shooting my daughter reading a book in the failing light of day, I'm going to shoot RAW.

Hope this helps!

BTW, RAW on the EOS-M requires a lot of computer skill and patience.

The AVC video from the camera undergoes sharpening and other processes. The RAW video does not. In post one can sharpen the video as much as one likes. I do not see why the RAW-origin video has to be softer than the AVC video (at same resolution, of course), since the AVC video starts with exactly the same input. I do not understand your saying the RAW is "upscaled."

Thanks, the other responder went off a bit on my soft comment. I've watched 720p videos on my 1920x1200 screen that look sharper than that one.

Great explanation of the crop mode raw shooting, and the best RAW video I've seen from a crop sensor. Do you have a link to a good workflow to follow for the edit?

Thanks

But it doesn't really look in focus, rather soft. Viewing full screen 1080p screen.

It is 720p, so if you put your eye an inch from your 1080p screen it will look soft.

My eye wasn't anywhere near an inch from the screen, back off.

Did you download the original? At a normal viewing distance, even for a 60" 1080p HDTV it should look great.

I viewed the video from the link, as I have no need to download videos to my computer before watching them.

I didn't say you put your eye one inch from the screen, I was just describing the phenomenon of viewing distance and resolution. The closer you are to a screen, the more you see the difference between resolutions. It will be more apparent watching closely on an HD monitor, when one is usually close (not one inch!) than watching 10 feet away from a 50" HDTV, the normal viewing distance for that.

The "need" to download is to actually view the original video. Vimeo compresses the uploaded original. So what you are viewing by not downloading is not the video I uploaded but a softened version. You don't have to do it, I was not asking you to do it, just asking you how you had viewed it. Now we know. All is ok.

Yes, I think it soft too, but soft in a good way. Part of the issue is line skipping. I think what it means is that to get a HD image, which is usually 16x9 from a 4x3 sensor, you need to cut a box out. That is, only use part of the sensor in your camera (which is less resolution of course). Here is a good image that shows that

http://forum.fourthirdsphoto.com/at...73-e7-new-bigger-sensor-size-imagecircle1.jpg

However, if you save the whole box as a RAW file/frame it would be too much information to write to the SD card. The camera would not be able to keep up. Therefore, they skips line to reduce the numbers of pixels saved to the SD card. Those skipped lines lead to moire and other visual issues. For example, if you're out on the street and there is a power line in your shot, that, say goes between two lines of sampled pixels, it will appear jagged in your video.

One way to fix it is to use a smaller box, with less need to skip lines in the sensor, but that crops the image, or makes your lens 3x. Think how a smaller box, expanded, is a larger image. So if I shoot cropped mode with my 22mm lens the image will display as if shot with a 66mm lens. For now, I can live with the softness because I'd rather have wide angle.

Sorry Markr sounded rude. I don't think he meant to be. He's been helpful to me. He's the first one I know of who put good EOS-M raw footage on the internet. I can imagine the frustration he must have been through! He's probably a little sleep deprived

Did some more tests with the EOS-M. Not beautiful video, but shows how the EOS-M does provide a higher dynamic range video in RAW mode. I think it very pleasing, even though there is a high risk of moire in non crop mode.

HOWEVER, the Magic Lantern hack for RAW video is not stable. I would not try it unless you have a high level of computer skill.


Ironically, the EOS-M makes me want the Black Magic Cinema Camera more, but also, less. With ML this camera is one powerful pocket photo/video production kit
