Yes, it wasn't meant as another "wish list item".

I would like to know if there's a restriction against S35 60fps though. I wouldn't think so, but who knows…
one would assume* that windowing down to s35 would allow for 60fps. i am surprised that ff35 got that instead.

*(and by 'assume', i mean generalize based on no real info)

I thought the HDMI will give you 60fps, if you choose a filming mode setting in the 1DC that have 60fps. Is it not so?

as for the 8-bit, I guess is file size ( data writing speed of current CF card) that is limiting this . Since the current 8-bit config already require a writing speed what the 1DC is just barely able manage with it current hardware ( CPU for coding, data bus for transferring the data). I do not have spare capacity to output 2 different data stream to CF and HDMI for 8-bit and 10 bit. This is why the setting of the 1DC seems more flexible in the non 4K modes.

Similarly the current HDMI1.4? port can only manage 1080p 60fps or 120fps? data rate. I guess not until they offer a upgrade to HDMI2.0 or display port we will not have 4K output on the HDMI.

HDMI out tops at 1080 60i, it's also a limit at circuit board level, in order to be compatible with consumer display.

I believe it has something to do with the sampling algorithm, FF mode 60p is the softest of all modes, pretty much like upscaled 720p.

S35 looks a lot sharper (1000 TV lines+), so a better, more sophisticated sampling algo is used here. 60p with this algo would put a lot of pressure on sensor read out speed, which could result in unacceptable rolling shutter effect (S35 and 4K mode already has some bad rolling shutter similar to 5D2).

I guess I can understand that. Though honestly, I know little about that. I just assumed if they could get 24fps in 4k, that a windowed s35 could get somewhere of 60p, similar to a few other cameras hfr, namely Scarlet. And that is why I say I am generalizing without context.

So are you saying the read out of the ff35 is skipping a bunch of lines, meaning less readout lines, meaning less resolution, meaning less needed readout speed? If that is the case, then I suppose the 1d is performing admirably, and the engineers at Canon have done some fine work.

The Jello only bothers me in 4K.

I really only feel 48fps is needed for some slomo in 24p. So, something sharper than 720 at 48fps would be preferred over blurry 60, but I wouldn't take away the 60fps option. The ff35 60p is nice.... similar to having a fast lens which isn't sharp wide open... sometimes it's nice to have the option.

May be. I do think 10bit in HD s35 would be verrrry welcome though. With the data rates the MJPEG is pulling, I am sure the CF cards could handle it. Red started writing to CF cards a while back.
 
Hi guys,

Just got my 1 DC today. a quick question. I've seen on Vimeo that if you set the camera to 4k recording and then record from the HDMI to a ninja or samurai, you get a pin sharp 1080p. Much sharper than the internal 1080p recording. Has anyone tried it?

Jose' Alkon has done some with that. He has written his thoughts on it here in this thread.

Between him and James Miller, I would assume it is worth while. Though, "much sharper" than the 1080 s35 mode seems not accurate. But Jose' seems to think the gradients are better, which has me wanting to try start using an external.
 
Interesting....

Any of you guys are using a viewfinder or a loupe? what is you favourite? thx
i definitely recommend the cineroid retina. Has all the functions and the resolution in a small lightweight package. perfect.

A hidden cost to some EVF's is external power. I find the best is to have a larger battery living on the back of the rig, and a power wire running to the EVF. But this can add hundreds of dollars to your kit. If you plan to use Canon dslr batteries, I would stay away from the Zacuto and Cineroid, the Canon batteries fall off frequently.

loupes are great too. i think any loupe will do these days. (they should start making dslr's with loupe hinges for 3rd party vendors to attach to.)

Funny enough I sent an email about 4 months ago to Philip Bloom about my findings but never got a reply I wonder if it had anything to do with James trying it out hahaha. Awesome video.
 
José,

Did you personally try it with the samurai blade?

I'd love to think "one stone two birds". Recording great images with an efficient codec on SSD and get a nice screen for focusing...

I used to have a SmallHD DP6 (5.6" at 1280x800). It wasn't always easy to to confidently pull focus on that size. It had peaking tools and such, but I prefer a clean image. I now have an AC7, also from SmallHD, and that is a comfortable size.

I believe that the Samurai Blade is a solid product. If I had it I probably wouldn't add an extra monitor, but I wonder how confident I'd be simply pulling focus off the 5" screen. On a 1Dc in 4k mode you want to hit those eye lashes and not the ears or the tip of the nose.

It will cost about the same ($1295), so I wonder if the much hyped Odyssey 7 (7.7" OLED) isn't the better long term buy.

And I'm saying that despite being more sympathetic towards the Atomos brand at this time.

Yes, I own a Samurai Blade and it is great for focusing sharper than my DP6 by far plus you also can magnify to check sharps on it. It has a great waveform that I use full time and some other cool features but it is not perfect as it does have some vital features missing (eg. aspect guides) that is a bit annoying. Maybe with new software upgrade as Atomos are constantly doing them.

On paper the OLED's sharpness sound better but I haven't tried one yet except high end Sony ones, the Odyssey seems incredible and side by side I would lean towards the Odyssey just on features alone but it's a massive unit when I saw in the flesh. Samurai Blade is smaller but bulks up a bit when you attach the HDMI-SDI adapter on the back.

I think Samurai Blade is still cheaper as once you add on all the bells and whistles to the Odyssey the price jumps up a lot, but I agree with Andree if you are considering a long term buy the Odyssey ticks all the boxes.
 
What about another option...

What about the hyper deck shuttle for recurring and a good EVF. maybe dp4 or Alphatron... Is that something you guys have considered. Like you I am tempted with a 7inch screen, But in may I'm going to shoot in California with some harsh light/sun condition and I wonder if monitor and a clothed over my head will be better that and EVF...

Any thoughts...

Btw thanks for all your advice. Much appreciated.

I have done side by side and hence the 'way' comment, I'll do a proper set up next week to post up but until then here's a simple test: have a look at the image quality difference between the two formats when connected to any monitor even a tv. You'll notice the resolution improvement straight away.

I have only used it on a tripod so cannot comment on jello effect but I'm guessing would still be there as it is a sensor and shutter issue not compression.

I had high hopes on the Alphatron, as I prefer to use an EVF, I was about to purchase one but then I tried it and found it unusable due to what I can only describe as lag when panning/tilting/moving. It is sharp and great but then you move and you can't tell what is in focus. I would love a 3rd party EVF like Sony's f55 one that is very impressive.

Anthony, it depends on what you are shooting, the style and how much you are willing to build up your camera's footprint. But when I tested a great monitor that also records uncompressed straight from camera I was sold.
