Helium squad

[Brett Harrison]

Anyone in Australia with a Helium? Looking to rent.

 

[Elsie N]

Am I missing something here but it seems that the Helium at 6KHD has less top frame rate than Weapon or Dragon. I don't have the numbers in front of me. Anyone?

My understanding was that the data rate moved from Dragon 200mbs to Weapon 300mbs - like a 50% improvement. So it would follow that the Frame Rates and RC's would also improve along that same line. True?

I've seen suggestions that the WEAPON MG will be able to be fitted with the 8k Helium sensor. If that be the case and assuming no change in boards, that is what may limit the Helium.

On the other hand, when installed in the CF WEAPON it may be possible to generate the numbers you quote.

I received my shipping notification yesterday. Helium is on it's way!

I am willing to ship, but only for long-term rentals.

Helium is in New England!


I haven't done any challanging tests with the camera yet. I did get my wife and son to stop and say hi for a quick moment on camera.

Here is a link to an R3D if anyone is interested:

Especially for macro work - it is incredible how much detail we can now capture in the same magnification framing. Can't wait to see this stuff projected in 8K...

looking good Peter - thanks!

Awesome Peter

Looks nice Peter!! I must say I'm astounded by the quality of mine. I'm finding it hard to go back to older 5k material. Just prepping a test that I'll get to see on Digistar 8K IMAX projector in October. Should be amazing. What are you going to be using for 8k projection?

We will be using prototype tech from the same "folks" that we have used to project 4K DCI back in 2005 for the Kurosawa project... ;o)
Hopefully we will be getting more make / models as we move along, so we can do direct comparison. This is the main reason why we building the dedicated 8K theatre with custom screen surface...

The devil is in the details and details is where the Helium really shines. For the above comparison we have simply down-sized the 8K source to 4K and 2K respectively (which already provides an edge when compared to straight capture at those resolution) and then up-scale it back to 8K to see what those resolutions would look like when projected on the same size screen. When we have more time - we will do proper comparison against the Raven - 8K vs 4.5K - both S35. This will give us some direct pixel comparison between Helium and Dragon and how they respond to various light conditions. But off the bat - I feel like the Helium could be pushed farther then Dragon. Let's see...

While NHK here in Japan is pushing the 8K bandwagon - the rest of the world is still catching up to 4K. I believe 90% of the 8K Helium footage will be ultimately (for now anyway) down-scaled to 4K. So I have done a quick comparison between the Helium and the Raven - I know that the relative subject size is not equal, but you get the idea...:

Raven:

Helium:

And the compare after scaling the Helium's 8K to 4K:

And we need to remember that we are still at the very early prototype stage of the Helium - especially when it comes to Graeme's magic, the color science. Dragon, on the other hand, is well matured and pretty much at its best...
More tests are indeed in order, wish we had the VV as well...

[Jarred Land]

Very cool Peter, Very cool.

 

[Brad Grimm]

Peter, thanks, these are very telling!

 

[Mike Nagel]

Peter,

can u post a direct pixel comparison Dragon vs. Helium ?

Example: same images as above, just a 800x500 pixels crop of each sensor. so we can directly see pixel level performance.

The downsampled pics looks great, as expected.

Thanks.

[Peter Majtan]

MIke - the crops in the post above are at 100% (true pixel size). If it helps - here are the two respective R3D's:

[Mike Nagel]

sorry Peter, I meant before downscaling 8K->4K. I'll take a look at the .r3d files.

Thanks !!!

 

[Jarred Land]

those 1080p and 4k slices are lilely better than you normally would get from native 2k and 4k cameras as these slices benefit from oversampling.

Hey Mike! The bellow frames are at true pixel size before any downsampling. The Helium is larger as I extracted 800 x 800 slice to be scaled down to 400 x 400 for comparison with the Raven, but the pixels in the bellow images are at 100%...

Raven @ 100%:

Helium @ 100%:

Indeed!

We are having a massive typhoon hitting us as we speak. As soon as we can - we do a proper direct comparison between the Raven (using "just" 4K sensor crop out of the 4.5K native res) and the Helium - putting the cameras in the same exact position in the same exact light and using the same exact lens. This should really help comparing Dragon to Helium in terms of direct pixel performance. Would be awesome to have the VV-8K as well for this test (hint, hint Jarred...), as it has more powerful innards when compared to the Raven / MG Weapon. I doubt it will make much difference (if any at all) - but it will put those "rumours" to rest once and for all at the same time... ;o)
