  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Weapon 8k Queue

Michael Lindsay said:
Just to be clear? Everyone is chatting about helium 8k not vistavision dragon 8k (I am easily muddled by Reduser;-)

Apart from the big guys with really strong dev relationships with RED (PV, Vantage and RVZ) nobody has a 8k vista? .. apart from Phil of course who deserves a little bonus for the tireless work he does for the rest of us... even I can't begrudge Mr Holland;-)

Thanks M

Yes. this is nothing but weapons getting helium in the wait for big sensors so far.

Thanks Björn... i have tried to stop reading and thinking about the 8k dragon so I don't feel frustrated... but don't want to miss any big news;-)

Having helium to play with in the mean time helps, a lot :)

Noise levels is much improved. You don't have to pixel peep to see it. I just turned on the camera in my office and it all looks smashing clean on the 7" lcd in a way different way than weapon did. So don't know per pixel but when looking at the actual frame displayed on the same display as you used to look at 6k... helium is much cleaner. Then sure I also see some odd colors when among it towards heavily mixed lights then the highlights looks like they done in some there threads on this forum. But that is mostly post processing or the current limitation of running only redgamma and not redwidegamutRGB in camera. So I know it will look fine in post even though it looks a bit odd on screen. From testing back and forth it´s a pretty easy choice to make. Sure dragon got a few benefits of bigger sensor and a color processing that is already well balanced but it´s easy to see that helium simply got more to offer.

Thanks for the insight.. the imaging pipeline release will change a lot, I suspect.

Cleaner at 6800ISO for sure. No processing except for colorbalancing on a patch of snow on the ground. Tried to explain for my client how big those frames really are... He though 8k was about double of alexa raw, I told him it´s a bit more... when drawing it on the frame he had a moment of clarity :)

This image speaks a million words... thats for sure.

Uploaded the video clip to vimeo, sure it gets ruined by compression and such but consider it´s shot with a F2.8 canon still zoom in the middle of the night with only shit streetlights and kelvin 2800 / 6800ISO it´s not too shabby looking.

Björn, that Sensor Performance seems absolutely impressive! thanks for sharing. (is it only me or seems rolling shutter a bit stronger than Dragon ? - i mean i would definitely trade that off for that Sensitivity! and there is always motion mount if perfect Global shutter would matter... )

I don't know whats more impressive, that sensitivity or your moves over that slushy street!

BTW, Allocated today for Helium!!

I think I actually shot at 220deg. but to me it seems the rolling shutter is even less i been swinging that gimbsl like crazy and find the skew less prominent than before but have not done any scientific tests on it.
 
This came up in a Epic W Prores thread and I didn't get the answer I need so I'll ask it here since this is appropriate for my camera (currently up for sale but considering withdrawing that to shoot a two camera movie.)

A podcast I watched ( interview with Linda Nelson) said they (as Indie movie distributors) wanted Prores and were also big on 4k (and RED it seems)... so I'm wondering if you can shoot Redcode at high resolution + higher frame rates and then convert that to Prores and still exhibit the same?

Full disclosure... I've never shot Prores nor have delved into how to shoot Prores as I've had no interest before listening to the podcast.
 
For feature work destined for the big screen, even at lower budget levels, I'd suggest creating the ProRes files as your last step. If you shot only ProRes in camera, things like re-framing, stabilization and major changes from the baked in look are more limited. Note: if you encode the ProRes in log format, any "normal" grading should be essentially the same as from the R3Ds.

If you shoot both simultaneously to the onboard mag, then you will have to compress the R3Ds more due to the bandwidth eaten up by the ProRes. Rarely an issue for a 1080 finish, but not ideal for a UHD/4K on the big screen target.

I should also note - due to time, drive space and/or computer horsepower limitations some post pipelines might benefit from flipping the R3Ds into PR444, or DPX image sequences (especially if that's the interchange format for VFX anyway) upstream of the master. YMMV.

Thanks Blair.

That's the confirmation I was looking for.

You tested side by side?

Pretty unscientific, but I did shoot a sports event which I shot 2 years with Dragon, and I did notice the rolling shutter more with the Helium. Probably the crop factor for faster frame rates made it more noticeable. Not a deal break though. We are not talking 5D Mark II rolling shutter here.

yes its no deal breaker. tested my gimbal with it the other day and I think this is actually 360 shutter, you can see the scew but to me it´s not much considering the amount I pan per frame.
