General Help Q&A / Re: Help! My Raw video are bad quality

« on: November 01, 2013, 03:45:24 AM »

The only thing in focus in your shot is quite dark which means the SNR is low, and it appears you are in quite a poorly lit space. Noise and resolution go hand in hand. Increased noise effectively decreases resolution.

Go somewhere with some light and find a better subject! Use a smaller aperture so we can rule out focus/lens issues and so that you have more of the shot in focus, use a large well lit subject (you have a tiny dark object for comparison and that's it). Also try and make your subject the same apparent size on each camera, the crop factor makes it hard to compare.

RAW is not all about improved resolution either, it's about color fidelity and increased dynamic range (also reduction of H264 artifacts like blocking, which you wont see on a static scene). There are tradeoffs, it's not a magic bullet, and you really have to know what you are doing to make the most of it. For starters you're using a digital ISO, which is pointless on RAW, in fact ML actually just ignores digital ISOs and only uses the analog ones. Also make sure you ETTR for the best noise performance.

so why did the GH2 outperform it so much if they were both in poor environments?

Also this part about the ISOs, so it doesn't matter to use the "good" ISOs when shooting raw?

First of all, the GH2 screenshot is really noisy and flat as opposed to the smooth and vibrant shot of your 5D.  Are you using noise reduction/sharpening in adobe Camera RAW?  Because if you are.. that's your problem.  That works good for still images, but not video.  Use NEATVIDEO plugin for noise reduction and sharpen in your video editor with plugins made to sharpen video.

Also, you don't need to reply the same post to everyone LOL.. we're here for you, don't worry!

The GH2 is set on the flattest picture style, so it's intentionally like that. In sharpness though it's wiping the floor with the 5D raw...

No noise reduction was done at all, that's the DNG file right there, converted straight to jpeg... I feel like all the sample raw videos I've seen on the web have looked much better.

Did you focus the lens? Did you record in a low resolution? Are you using a low resolution preview in AE? Open a single dng frame in photoshop and post it here.

highest res possible (1872x792 I think), native res in AE. Focus was spot on, I zoomed in to confirm.
Here are some screens for comparison:

my GH2, ISO 1250, 1/50, same lens


My GH2 is destroying the 5D RAW right now...

I need help in this too   Though I feel I know the answer, just can't handle the truth   Here are two images I took with my EOS-M.  I think they represent the difference between RAW and H.264 for all cameras.

http://www.magiclantern.fm/forum/index.php?topic=8825.msg82956#msg82956

RAW gives us what we want, pixel level image data.  Unfortunately, it is very noisy (keep in mind, each pixel is reading under a different color filter).  H.264 does so much chroma smoothing is appears like we're getting noise-less (not "smudgy") video.  This is especially true in any shots not lit well for low ISO.

The truth I don't want to handle (hopefully others will chime in here) is that you need to do a lot of work to RAW to get an image with just the right amount of color fidelity and smoothing.  Right now, I live with a lot of noise.  When I start to think about going back to H.264, I just compare some footage.  Sometimes H.264 is perfect.  But when shadows, and color are important, I'll live with the noise.

Will be curious your ultimate conclusions.

For what it's worth, here are some screens for comparison:

My 5DmkII, ISO 1250, 1/45, Rokinon 24mm T1.5 at T2


my GH2, ISO 1250, 1/50, same lens

I get sharp video and lovely grainy noise with my 5D2.

You are new to the RAW phenomenon and doing something wrong.

And post your settings.

I think that he was talking about the attitude of superiority and condescence...

We're all here to learn together.

Most of us, read and try to learn and participate. We're not in the high school classroom and don't deserve "teacher-like" attitudes (writing imperative orders in RED... really??)

best regards.

I agree with everything you say, but it doesn't apply here. TheDCMule didn't ask a question. He tried to tell other people things about ML as facts, when really they weren't true. Straight up misleading, 100% bullshit. When I read his comment I believed him, but now I'm a little irritated when I find out it was a lie.

I find nothing wrong with Renato trying to keep people in order to not spread misinformation. ML is confusing enough as is without people throwing misinformation around. Red text pops out at you so you really get it right away that what was posted was NOT true at all.

Thanks for the reply. Actually I come from a photography background so I'm very very familiar with RAW and how it works, with bit-depth and all, the whole shebang. Hearing that the 5D could do Raw VIDEO is what sold me on it.

This is actually why I don't understand why my video files look like they do. I get everything about sharpness being about contrast, so I think I used the wrong word, I didn't mean to say that my files are "unsharp", but rather that details are mush and unclear. Not pixelated, just smudgy.

Let's go back to the basics.  You realize that RAW video is just that, RAW.  More detail does not equal more sharpness, just like when you look at an image in the Wall Street Journal up close and all you see are dots (not sharp), but further back, the image seems sharp.  If you apply a sharpener to your image I wager you'll have that AH-HA moment.

You want to understand DNG (non debayered imagess) and how many settings can influence how they look to you.  Natively, they look like green puke.

Sharpness is a function of contrast.  The RAW images are as close to 0 contrast as the camera can get.  Another thing to keep in mind.

Once you pass this hurdle you'll be tortured by a bigger problem, when is it too sharp?

I'm amazed at how much I've learned about digital photography in the past 3 months working with Video RAW.  I suggest that too, that you realize what you're really doing is taking 24 RAW images a second and to understand RAW from a photographer's point of view.  It all applies.  You're not in Kansas anymore

Thanks for the replies. Unfortunately I won't be able to for another 10 hours or so, but I will. I'm not sure as to why that would help though. Let's just say it doesn't look good. Even when I pull the raw DNGs from the camera into Lightroom, they look unsharp.

FWIW, I've been manually focusing, and nailing the focus, so it can't be that.

Is there anything that has to be done other than load the raw_rec module, choose your resolution, and shoot?

I will upload a screen cap soon, I'm at work right now, please bear with me...

Hey all,

So I just got a 5D mk 2 and installed ML on it... The results have been super disappointing. I pull the raw files from the camera, use cinema2dng as required, and put the DNGs into After Effects. However they're not sharp at all. It looks like the H.264 quality or maybe worse, and even my Panasonic GH2 unhacked is sharper. Basically it looks NOTHING like what I saw in these videos:

I got the latest build, tried it, was disappointed, and got the newest nightly build, and got no better results. Would you happen to know what's going on? Thanks!

I was shooting at the highest resolution allowed (1897x792 or something), ISO 1250, 1/45, at T2 with the Rokinon 24mm Cine Lens. Used raw2dng to convert into DNGs, and the DNGs didn't look good...

there are 2 flavors of peaking on the mkII. The older one uses color to indicate areas of focus. There is also a newer addition called Digic peaking which renders areas in focus as slightly sharper. The latter is faster and less distracting than the former and I find it to be more accurate than the older color overlay method.

I see, that sounds great. Are there any samples online of the digic peaking in action? And just to confirm, this does work flawlessly while recording RAW, correct? Thank you for the information, i appreciate it a lot, and sorry for the pestering with questions, I just want to make sure before I commit to buying it...

Just out of curiousity, while shooting raw at continuous 23.976 fps, can I use focus peaking on the LCD while recording? I am considering buying a 5D MkII and this would be a dealmaker/breaker for me.
