  1. Perhaps try ticking the maximum bit depth option at export, it processes the video in float point. If you untick it it will be processed in 8 bit space.

    When editing, timeline video tends to play back at draft banding and scaling unless you tick max quality and max bit depth in sequence settings, which could be the cause.

    You may find that such things aren't on your exports if you use maximum settings, even if they appear in the timeline draft mode. Certainly I have no such problems.

    Many After Effects users complain of banding in their animations, until they realise they need to render in something other than 8-bit for the engine! It's often missed by users.

  2. C100/300/500 do a downscale from 4K in the body. If you record that from the HDMI ot's pretty damn sharp.

    C100 MKii is the first to take all three 4K channels, then combine then downscale. So it appears it's even sharper 1080, and will upscale to 4K pretty well!

    C series are very sharp, sometimes it feels like too much. I'm not yet delivering anything 4K so it doesn't bother me for now! I'd say if it's a huge effort for little reward don't do it, and if you can see the difference and feel it's worth it, do.

  3. You always use post, but the material you take into post affects where you can go, and how far.

    Canon starts off very over warm, but there's a lot of wiggle room to remove that, so I like it. With others I find it hard to convincingly add that warmth if I want it, so I like Canon quite a lot.

    Arri just nailed it for natural "do anything go anywhere" skin, amazing. So really the Alexa and Amira are the winners, at a price. That's one reason why so much film, TV, advertising, drama, so much everything are shot on them.

    Red is good too, though there's sometimes a funny green/magenta tint that I find hard to knock out in a consistent way in post. I find it less forgiving.

    Sony is very cool feeling but quite Kodak'y so not at all bad I don't think, just different. The rest I don't really have the experience to call.

    That's my two pence from my experience, but YMMV of course!

  4. I saw one of the earliest big 4K monitors at NAB one year.

    The shot was of a Samurai walking down a gravel path. I quickly realised I was staring at the detail of the gravel rather than the actor's face!

    I also saw plenty of Sony 50p and 60p that year, and found it plastic and dead. Too much like real life.

    Since then I never really obsessed much over resolution or HFR, in fact I often blur footage slightly on purpose! It feels dreamier, and the best movies are kind of like waking dreams I find...

    Wildlife, sport, reporting and some kinds of documentary suit both well I'm sure.

     

  5. As an addendum, and slightly off topic (apologies) the debate about the quality increase when increasing sample rate never ends. When mixing many tracks together 96khz allows frequency interactions above hearing range to be blended in a non-truncated manner, resulting in a final mixdown that's less congested, though it's quite subtle really. It is worth doing though.

    interactions between high-frequency elements can create peaks of frequencies beyond the capability of the original capture rate, and slicing these off by working a mix at 48khz can create a bit of a tight feeling -- a lack of air -- so basically record at 48 and mix 96 will do you good.

    quad rates like 192khz are pretty excessive unless you're altering audio speed. Some argue this point. Dan Lavry wrote a pretty deep paper on it. If I'm honest, the DSP maths in that paper is lost on me. but a 96khz environment is beneficial even with 48khz sources, audibly so with good monitoring.

    Bitdepth wise, 16 bit dynamic range is fine for delivery. For recording, do 24bit. Your software will probably mix in 32 or 64 float by default. If not, set it to 32bit yourself.

  6. Looks beautiful! It's the first time a company other than Canon has produced colour response that nice in a consumer camera. I think it'd cut with Cxxx footage well

    Im sure h265 will be in Premiere in not too long! The only thing missing here is some kinda stabilisation in body (I'm being greedy)

    id love to see some 120fps examples. In fact a slow motion shootout with a ton of cameras would be a great article

     

  7. Red files don't require transcoding in Premiere. Drag them in and play.

    i nearly went for this too. The only issues were size complexity and PL mount.

    lenses are expensive, the whole thing weighs loads Especially with big Anton Bauer batteries or similar, but the image is brilliant and gives you an edge. I like to work quicker and lighter than Red allows so I went against it, but do consider it. Hire one and try it out!

  8. I guess it's just much harder to stabilise full frame compared to four thirds.

    It's a much larger area and probably much more difficult to eliminate rolling artefacts across it, without greatly increasing scan speed, that is.

    You'd probably need some clever software stabilisation too, analysing the movement sensor and trying to counteract rolling shutter too.

  9. I have no faith, i have wandered from the path. I use C100s for nothing but convenience (plus Ninja for lovely quality), and unless Canon rise again and roll away the rock an FS7 will come next.

     

    I loved my 550D, but all things must die...

     

    The 5D MK iv will not be an inspiring product for video makers. I'm happy to state it outright and wait to proven wrong. I'm sure I won't be.

  10. How can the sensor output 6k video (or even 4k video) when it only has 4.44M active pixels?  That's more like 1080p-class resolution. The only way I can see it outputting 4k video is if it upscales its 2166 vertical lines to 3180, which can't help but look nasty.

     

    assuming Sony use their RGBW system, creating a red, green, blue and white pass using an electronic filter:

     

    4.44M * 4 = 17.76M = 18MP

     

    18 megapixels is about 5760 * 3240, roughly 6K

     

    So the maths points to a very high colour depth indeed, combining full colour and a monochrome channel. Of course, they're then having to stretch this out to 6K final spacial resolution, so like Bayer, there's trickery involved.

     

    The only way to get true 6K (as with any resolution) is either user three 18MP sensors stacked, split by prisms, or use one Bayer sensor with four times the pixels. Still, it could be the best picture ever... ;)

  11. I've been fooling around with using DNxHD 220x with Ninja 2 attached to C100 MK 1, and for C-log it's pretty incredible how much of a difference it makes. You gain a ton of detail (yeah even more!) and colour separation, secondaries work incredibly well... you basically gain a stop or so of usable dynamic range as you don't lose all the detail in the darks. it's quite brilliant.

     

    The price of C100 MK 1 and Ninja 2 are both dropping so in combination it's gonna be really good for indie film making, just jack the audio into the camera too! I don't mind using the AVCHD for reporting and that kind of thing, but the DNxHD has ten-times the data and whips it into touch if you want to do post. IT ain't 4K, but it'll look damn good.

     

    For promos and slow motion stuff though the FS7 is a much better bet, but it'll cost you twice as much. OR you can hire it for 150 a day. It seems it maintains the Sony cool, Kodak-y look, which is certainly a look. It's one i like, though it's not as friendly as Canon.
