  1.   I think the problem is doing a high quality debayer on the raw. The compression to JPEG isn't the processor intensive bit. It is the debayering.   All the camera has to do for DNG is dump the 1s and 0s to a very fast 512MB buffer memory chip. Then write 512MB to the card (that takes longer).   Imagine with every DNG file having to process all that data - 5MB of it - like opening a raw file in Photoshop - but in-camera.   Clearly the camera is doing a very simplistic debayer of the 2K raw to provide an image for live view and the H.264 encoder.   But we need a much higher quality one for decent 1080p MJPEG, otherwise you may as well stick with the existing H.264.   That's my understanding of it.   DNG is the option with the least processing, least CPU intensive, but sadly the most data to shuttle off to the card.   Of course Blackmagic cameras debayer their 2K raw just fine to ProRes in-camera, even the Pocket Cinema Camera. So it is doable with today's technology. What Blackmagic are doing could be very specialised though. Whether Canon have that technology, I don't know.
  2.   You'd be surprised how hard it is to do with digital what he did with film.   First DSLRs are out. People react differently to a big lens and camera.   You could pick a small mirrorless camera, but none of them are full frame so the look isn't the same as a Leica M3.   Of course you could just get a Leica M 240 but if I were spending that much it'd go towards a film not stills!   Oddly enough the Nikon 1 V2 with 18.5mm F1.8 came pretty close for decisive moment street photos. Superbly fast AF, tiny, and very good built in EVF. It's just that the Sony RX1 has the quality and look of 35mm film, whilst the V2 has the quality of a good digital compact camera.   I didn't get on with the Fuji cameras. As a poster said above, he said he felt the Fujis are better street cameras. I just don't agree. The X100 had a miserable focussing system whether in manual or AF mode. Not responsive enough for a decisive moment and of course it isn't full frame. On the X Pro 1, I had several issues - again a terrible feel to manual focus, dreadful AF and some horrible electronic noise reduction going on in the raw file processing which I couldn't turn off. The hybrid viewfinder which worked well on the X100 didn't suit the nature of interchangeable lenses and the body was way bigger than my Olympus OM-D E-M5. It was the worst £1900 I'd ever spent.   I liked the X10 compact better, but it ain't no Leica!   I've tried the new X100S, love the split-image manual focus assist - just like with a Leica you immediately know which way to turn the focus barrel to lock focus and you're not tempted to hunt around slightly for a perfect lock on. The feel of the focus ring is much improved too but the AF is still well behind Micro Four Thirds and Nikon.   Canon EOS M AF takes 5 seconds to lock focus in good light and that has phase detect AF pixels on the sensor... But then that's Canon for you.   NEX 7 and OM-D E-M5 are fine efforts but they just don't have the full frame image quality going on that a Leica M or Sony RX1 gives you.   I hope that gives some perspective as to why I think the RX1 is the best tool yet for doing decisive moment street photography. I can't think of another one of my cameras I'd rather use for stills, unless it is a particular lens I'm looking to use on the GH3 / 5D3.   Video of course is another matter. I'm baffled by Sony's slapdash implementation of image quality on it. They think they can get away with it in video mode but they couldn't do that with stills! I can only assume the Japanese designers really don't care about video. Only stills.
  3. Added full resolution 24MP 6400x4000 JPEGs (from raw) http://we.tl/VuaRBuQBo9
  4. The Sony RX1 is a compact camera that beats Leica and Hasselblad for image quality. [url=http://www.eoshd.com/content/10248/sony-rx1-review-stills-camera]Read the full article here[/url]

    GH3 Guide

    Yes there is and not too far off now. I've been writing it for the past 9 months!!
  6. I don't know Andy... The 5D Mark III and D5200 look a lot nicer with a bit of sharpening in Premiere. Not something I'd usually do and I never had to do it with the GH2, but to make the images pop a bit more it does help. True if you go too far you get an awful scratchy feel that isn't organic and on some cameras you can't do it at all because it just brings the artefacts out like on the 7D and NEX 5N.   Take a look at how close the 5D Mark III is able to get to the REAL resolution of the GH2 once you help to bring it out in post. It isn't about sharpness but just making the detail a bit less muddy.   Organic softness is good - I'm totally in agreement on that - but muddy detail is horrible!
  7. At the moment heat is not the bottleneck. Let's try to stay on topic please.
  8. I agree eBay is now heavily biased towards the buyer, some people I've dealt on eBay treat me like a shop, one day I will have to don a badge and uniform and deliver the camera in person with a cheesy smile. It isn't much fun working for eBay!
  9. Try sharpening this one, it is less compressed for the interwebs...   http://www.eoshd.com/uploads/d5200-sharpen-this.jpg
  10. You are trying to sharpen a heavily compressed JPEG downloaded from Wordpress.   I'll see if I can find the master MOV clips and upload. But I am quite busy on testing the 5D Mark III raw at the moment and finishing off the Sony RX1 review.
  11. Consider this - the hacked 5D's 2K raw image is better than the 1D C's 1080p.   We are being diddled.   The more that comes out the more I am sure of it.
  12. It's funny that these guys were laughing at the DSLR crowd a few months ago, kind of ribbing us about how easily people get excited about raw when what really matters is the script, etc. etc. etc. etc. etc. etc. etc.   And now the joke is on them! Remind me what the C300 shoots again... Erm is it 8bit mud!?
  13. No, that theory is discredited unfortunately.   If you convert compressed H.264 to 10bit ProRes, it is the same to grade as the master files. Transcoding gains no extra image quality. I once read a very good blog showing this but unfortunately I forget the source. Unless you're trying to fix a compatibility issue like 5DToRGB did with GH2 footage and Quicktime on a Mac, you're best off dropping the original native clips straight into the NLE.
  14. The CF cards are certainly cheaper than spending $8k on a 4K recorder for the C500. Well, it's less than that now thanks to the Odyssey 7Q but you get the point.   However, the fact remains that the 1D C does its image a huge disservice by offering zero changes over the 1D X for double the price, other than the image itself. Zero. Nothing. Put that image in the C300's body Canon please. Next time they may get it right.   And whilst they're at it, please sort out the low end and DSLR video. It is a bloody mess. More video features are being reversed engineered out of the 5D Mark III than Canon's own engineers added in the 3 years between the 5D Mark II and 5D Mark III. They could have 2K raw video, maybe also 3.5K MJPEG 1:1 crop in that camera at the drop of a hat. I have no idea what the hell is stopping them.
  15. Which frame are you referring too? Is it this one -   http://www.eoshd.com/uploads/d5200-sharpened.jpg   It surprised me too.   Just try downloading the full JPEG and sharpening it in Photoshop, you will get the same result that I did.   There's not much in it between the GH2 and D5200 but the GH2 does still have an edge for resolution and the D5200 is much better in low light with a cleaner codec and larger sensor.   By the way the D5200's sensor also ranks very highly for stills at DXOMark, basically the best APS-C camera out there for image quality. Toshiba really did do well.
  16. You can't uncompress compressed video, the data is lost forever.   Upscaling is a different thing. DVD players used to do it. Standard definition DVDs to 720p. Sony's 4K TV will do it with 1080p. I don't know of any plugin or workflow for Premiere, Resolve, Final Cut Pro, etc. that does it. I find that a glaring omission in the editing world!
  17. Canon can't take legal action if they tried because it isn't illegal, nor does it infringe copyright. Canon should take the approach of Panasonic. Welcome the project, then build the features into the next model.   Just the fact that they have added DNG and 30fps raw bursts is incredible enough in itself.   To get raw video would be truly beyond anyone's wildest dreams, beyond even a Philip Bloom April fools.
  18. eBay fees are truly crazy. 10%! You are welcome to sell the GH3 here, good luck with the sale.
  19.   The Cinema EOS line would not suffer. Which pro with $$$$$ to spend needs a hack? They need reliability. They need ergonomics. They need standardisation. Image quality is important but only one factor. Canon are wrong if they think DSLR video will cannibalise their C300 and C500. Maybe the 1D C would suffer... But I can't see someone like Philip Bloom selling his C300 and going back to a DSLR + Magic Lantern just for image quality.   For the creative bandits like us who just want world beating image quality and are willing to be brave, the hack is perfect.
  20. I don't see how they can intervene other than encrypt firmware on new bodies leaving the factory and even then they shouldn't, because if this raw video hack takes off sales of 5Ds will go THROUGH THE ROOF.   Indeed what is the point of the 1D C I have asked myself that many times!!
  21. The image is processed before it gets to the HDMI port so unlikely to get the raw feed off the camera that way without dramatic changes to the way HDMI works.   I think it is more likely we'll see a crop mode of some kind first, at lower resolutions, written as DNG frames to a fast CF card. But I'm speculating there. We'll just have to see what Magic Lantern comes up with. Exciting times indeed.
  22. Wild Ranger - that's the million dollar question. Nobody knows yet.   Here's a 3.5k sample frame I just shot in silent stills burst mode at 30fps...   http://www.eoshd.com/uploads/ml/56420194.DNG.zip   You should be able to open it with Photoshop if your Adobe camera raw is up to date.   Image quality is stunning, no signs of moire. I think it looks like a 1:1 crop of the sensor. It isn't the full frame, more like a 1.3x crop horizontally and a much more severe crop vertically.
  23. I could do, it works just like the Nikon V1 burst mode.   Just need to transfer Magic Lantern to one of my faster 1000x cards as only getting 15 frames per burst on the 600x card.   The End Trigger mode is interesting - this appears to capture endlessly until you let go of the shutter release, then it writes the last few frames to the card.   BTW - with getting 3592 x 1320 raw burst with a certain combination of settings - is this documented normal behaviour?
  24. Download sample 2K DNG file and see the image quality for your own eyes! Recently Magic Lantern had the breakthrough discovery of beautiful pin sharp 2K sensor feed in raw format on the 5D Mark II and 5D Mark III. This completely turns our understanding of DSLR video image quality on its head. Canon claimed the 5D Mark II line skipped on the sensor to produce video. I don't understand how that can possibly be the case.
