Re: Kinefinity Terra 4K
 

So what are you claiming Gary that H.264 all-intra is twice as efficient as ProRes or only XAVC-I?

Re: Kinefinity Terra 4K
 

At least twice. It's three generations ahead of MotionJPEG, what about that do you not understand?

Re: Kinefinity Terra 4K
 

Yes, at least twice as efficient. As I said, ProRes is (was) a nice codec but not very efficient and was never intended for acquisition in the first place.

Re: Kinefinity Terra 4K
 

ProRes is a great quality CODEC today but let's all agree that it's now a dinosaur. Yes, it will STILL give you fantastic quality and HQ is very durable in post against stretching and bending and lifting. However, it was created in a time when computers were MUCH slower than they are today. It uses relatively simple DCT calculatuons that literally go back to the early days of .jpg compression.

H.264 is FAR more advanced, effecient and just plain "smarter". Not just long GOP and the estimation tools and entropy calculations but in all I frame too!

Look at the Lumix GH5's 10bit 400mbp/s h.264 all I frame CODEC. If you have ever shot 10bit V-Log with it, you will see that its pretty damn durable. Just as tough as ProRes but lighter weight.

I like both CODECS but I see it like this:

H.264 All I frame = Tough durability, light weight but need more CPU playback hoursepower.

ProRes HQ = Tough durability, heavy on size but easy playback on low horse power CPU computers. (Good if you have a five 4k camera multi-cam editing job on fat RAID drives)

I like them both but for different reasons.

BACK TO Kinefinity Terra 4K!
 

Thanks for all the Codec discussions. Now, back to the Terra 4K (watch this short action film)

Re: Kinefinity Terra 4K
 

Troy, will you be posting some of your own work soon? How are the files to work with in post?

Re: Kinefinity Terra 4K
 

Good Day Dan! Just recently received the batteries for my Terra 4K (batteries are shipped in a separate package). I should have some time within the next two weeks to get some footage posted. I'll be working with DaVinci Resolve in Post.

Re: Kinefinity Terra 4K
 

Excellent footage!

It is clear that this camera has a great dynamic range and a good highlight roll-off!

Re: Kinefinity Terra 4K
 

Found this morning on their website! I take three, or get the MAVO for the same price!

Re: Kinefinity Terra 4K
 

Footage is well shot, highlights and DR unremarkable.

Re: Kinefinity Terra 4K
 

Completely agree, similar quality is obtainable with a wide variety of cameras.

Thanks Trevor Donovan!

Re: Kinefinity Terra 4K
 

Gary, your statement is absolutely true. The footage listed as "Luna Kids Cinema 2018" was shot by Trevor Donovan using the Terra 4K and Red Raven. Very similar quality (or at least the Terra 4K cuts well with the Red Raven). Not a big deal, but worth stating.

Re: Kinefinity Terra 4K
 

The more footage I see the more I like this camera.

Re: Kinefinity Terra 4K
 

Exactly, I feel this latest video could have easily been intercut with a GH5 or a A7 III and it would have looked equally as good.

Re: Kinefinity Terra 4K
 

I don't feel that at all, this camera is way better.

Re: Kinefinity Terra 4K
 

In what ways specifically?

Re: Kinefinity Terra 4K
 

Dynamic range and the colors. Also, it grades very well.

Re: Kinefinity Terra 4K
 

I don't want to seem unfair, so I'll segue my previous remark and stop there. But if you look around the 18 second mark of the Luna Kids video where the lady is paying for her crepe, you can see both characteristics at once, unremarkable DR and highlight treatment but also something else that I think is contributing to the overall look; I don't see pure black anywhere! Not in that scene, not in any of the videos! In fact it almost looks like (or resembles) IR contamination. The images seem to have a brown bias, greens are muted, the season could account for this or the grading but I've noticed the brown bias in previous Kinefinity scenes. It's an identifiable look that is different, sometimes nice, but I don't want it in all my films. The footage seems well shot but temporal motion looks like it was conformed to 25p from 50p. I'm switching /rant_off but I'm not ready to buy into the pre-release hype yet.

Re: Kinefinity Terra 4K
 

I think these are all a matter of grading. I think pure black is just as bad, especially if the roll-off is steep, as pure white unless you have really pure black or white elements in the scene.
Looking at the 18 seconds in, if you check the scopes you see that the person who color corrected this video is leaving super whites. Pulling them down to legal does actually remove some (but not all) of the clipping. Looking at the scopes blacks seem to have been raised in post.

So I am not particularly convinced this was the best grading.

Left picture is a detail of the original file, the right picture is the same detail but after the lowering of the super-whites and lowering the blacks.

Re: Kinefinity Terra 4K
 

What do you mean by the dynamic range specifically? How about the colors? What about the colors...specifically?

What do you mean by "grades"? What are you doing to the Kinefinity ProRes (or cDNG) clips exactly? What do other formats (such as the H.264-based codecs from other cameras) do specifically when you try to do the same kind of process as you did with the Kinefinity clips?

Re: Kinefinity Terra 4K
 

How would you know this based on what is, most likely, a second-generation 8-bit 4:2:0 H.264 encode? I would not trust ripping a clip from YouTube to tell me anything about the original source.

Re: Kinefinity Terra 4K
 

You know I am not going to be in the defense seat, it's clear you have another opinion.
I have a feeling you do not respect my opinion at all, so what is the point?

I gave my opinion, I like this camera very much!
I guess I must be guilty as charged!

I base it on the encode the upload contains super-whites. Simple as that! Who, except you, is talking about the original source!

Re: Kinefinity Terra 4K
 

I can't ascertain if your opinion is worthwhile because of answers like this. When you say you like the colors and dynamic range and that it grades well, I don't know what you mean. It could all be confirmation bias. And in "grading", I suspect that you mean adjusting contrast and saturation, perhaps every once in a while adding a LUT. That's not really grading, and any camera, even AVCHD, can easily handle those operations.

That's fair, you can like whatever you like for whatever reason, but it does not detract from the idea that the Terra 4K doesn't have anything I don't feel you can already get with a GH5 or a Blackmagic Pocket Camera or an A7III.

How did you download the video that you tried to fix the grade? 4KDownloader to pull the YouTube encode? Which is probably a re-encode of what is probably a YouTube preset export from whatever the NLE was? How would that be helpful to determine super-whites and whether IR contamination is a problem?

Re: Kinefinity Terra 4K
 

I don't know but if I ventured a guess, Cary used a BMD Decklink capture card. He is savvy, his knowledge and grading abilities are without question. So what he is saying is that he got a hold of the source by whatever means, and it contained super whites. It's another way of saying if the source Ycbcr 10 bit word contained data above code value 940 or below 64 (blacker than black), the data points would be clipped from viewing. He made that point by pulling the highlights below 940 where they reappeared.

There is not a conclusion about DR that can be made from this in isolation, just that the video isn't technically graded well. The colorist made the overall image to his liking but in so doing clipped the highlights. You just have to take any observation about DR as an opinion in the absence of hard testing, which itself has some subjectivity and maybe even that has a grain of salt. Remember the hue and cry when Alan Roberts of BBC, the most renowned tester in the world using the latest methods contained in EBU Tech 3335 came up with a DR for the GH5s of 14.6 stops, he was ridiculed, but as far as I know, not disproven.

It doesn't change that I am not as enthusiastic about the Kinefinity , but I might be more inclined by video with properly recorded levels and not the obvious clipped zones I saw in these, and saw some un-hued blacks.

Re: Kinefinity Terra 4K
 

How would using a Decklink to capture a YouTube video add anything to a video that might be playing back as a second generation 8-bit 4:2:0 H.264 encode?

Re: Kinefinity Terra 4K
 

It could not add anything per se, except super whites and blacker than black are still applicable to 8 bit, 16-235, even 420 VP9. His position was that highlight detail was revealed in the super white region which would be above 235. While those data points might not have been displayed, they could still have been conveyed in the 8 bit word. That said, I'm speculating because he hasn't told us how he got hold of the source. All we know is that he demonstrated there was clipped data that he recovered. So if that's the basis for his opinion, no one else has the same benefit of it and these particular YouTube videos are worthless for critical evaluation, which well may be the case.

I'm sure this happens a lot, not just YouTube. There are so many places where legal levels can go wrong. And they get "fixed" wrong as this video demonstrates. In other words it can look flat or crushed to the colorist because the levels are wrong, but his fix is to use the grading wheels.

So I don't really know, it's his prerogative to explain or not, but I am certain that he is correct for finding the buried details in the super whites. And I am correct for noticing in several videos now, that DR and highlights were unremarkable. If people don't make critical observations and otherwise just roll along with the excitement and hype, we don't advance the science nor improve the art, or make bad purchase decisions.

Re: Kinefinity Terra 4K
 

While we are talking levels, above is an opposite case, the video output is video levels upon video levels.

(Note that the scope in DaVinci Resolve reports 0-1023 as the levels-independent visible range where black is 0 and white is 1023, this range gets properly converted to limited or full range depending on the delivery settings).
