  • 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 :)

4K HDMI output

I think they will show at nab. Just a guess
 
I noticed no one is jumping on this - but it would be quite valuable to preview at 4k on set
understood that is a different chip and maybe more expensive computational conversion - but Sony a7r does it (albeit at 8 but 4:2:0)
what is the price difference to get 4K hdmi2 (even if 8 bit)?
 
I had really hoped that the move to the DSMC2 platform would have brought us 2160P over HDMI2 on even the base expander. I hold out hope that a module with some version of the RedCast engine and lots of other functionality will be shown at NAB... By RED or OffHollywood or ...

8 bit 4k hdmi would be nice

Same here...

That's my only disappointment with the Weapon body is that it did not include a 4k output. Would love to live view in 4k for critical focus and general viewing. Would be very helpful for 8K ;-)

Even the new $1,000 Sony a6300 has 4K out via HDMI in uncompressed 8-bit 4:2:2.

even the weapon that shoots 4k prores doesnt have 4k output?

No RED camera has a 4k output natively... At least not yet.

The 4K broadcast module was the only 4K monitoring output for Epic (and that was pricey). Weapon has no option yet.

Would be good for it to get an option soon. Shot some 'C' roll picks ups the other day with an A7RII and a pix 4K recorder. Footage was surpassingly good for such an affordable set up. That camera is minute by comparison so I can't believe the boards in the MG and CF can't handle it. I am sure it will come. It took a little while for us to get full size HD out of the SDI at one point on early Epic but we got there.....
 
Yeah pretty much every 4k consumer camera has 4k HDMI out and no RED does without a $7k REDCAST module. I'm sure there will be a REDCAST2 module for Raven eventually but it will almost definitely cost more than the camera body...
 
It would be nice. I don't see a reason why it's not available in the Weapon or maybe even the scarlet-w but you can't have it all for $6K!

Hopefully well see a fairly priced expansion module with a 4k output.

I am not sure in today's value driven camera wars that it is a big ask for a high end product to not offer this without a module. One of the things that is nice about the Red W series is that despite some gripes it is a lot of oomph in a nice little form factor. Modules strip it of that edge to me. I have to believe that with a few firmwares etc they will figure how to squeak that out and it will be another feather in the Red cap.
 
we still dont know what those M3 ports are on the camera, maybe a tiny 4k output side module :)
its funny, for years ive had clients on set saying, so are we seeing 4k???
 
4K would be great, especially for popping my Shogun or Odyssey to the top and dual recording and what not. Pretty sure it has to do with a board or coding and with RED always wanting their products to be perfection, I'm sure they don't want to open that HDMI port to 4K until they're positive it'll match the quality of the internal recording. Plus ... it would cut a bit into the CF internal 4K territory.
 
It does seem probable that RED doesn't want a UHD/4K spigot on the camera that people could record that didn't measure up. Even HDMI2 (let alone 1.4a) would seriously compromise signal quality - particularly bit depth and color sub-sampling.

I don't have an issue with paying $5,000 or so for a rock solid UHD/4K output module along the lines of the DSMC1 RedCast. However, I am concerned that once it occupies the rear mount then there's no place to add an OMOD or Red expander. This means you either get a nice UHD feed OR the many useful features on an expander, but not both simultaneously.

In my perfect world, a Red expander or OMOD with the RedCast engine included - even if it costs $10K - is the droid I'm looking for.

While that may be possible for the higher end productions and customers, it doesn't make sense for Scarlet-W and Raven...

Saying the quality is compromised is kind of ridiculous. We have an uncompressed 1080p 422 feed out of camera now. Why not 4K uncompressed 422? A $1,000 Sony a6300 has UHD output via HDMI 8 bit 422 uncompressed. That would be perfectly acceptable for viewing on set. Sure, 10 bit would be better, but this isn't a final image that were looking for, just a 4K viewing option for critical focus. People will choose to record that signal whether they want to or not, no one can control that.

I see plenty of terrible RED footage out there that was captured RAW. So using the excuse that RED wants to limit a 4K tap because it doesn't measure up is laughable. I see footage daily that looks like complete shit or is noisy and underexposed only to find out it was shot on a RED cam. There will always be bad footage coming from any cam, regardless of the brand and regardless of the capture method.

I just think it's time to give everyone what they want, which is 4K out of the brain. It's kind of funny that the all time resolution pioneer and champion, only outputs 1080p for viewing on set. It's time for 4K out of the brain directly. No $5k or $10k module to make it possible. If you own a Scarlet-W or Raven, there's no way in hell you're dropping $5k-$10k for a 4K output solution. It just financially doesn't make sense. I mean, back to the $1,000 Sony a6300.....
 
Good points Ryan, and I too think an 8-bit 422 uncompressed UHD/4K signal would be sufficient for production monitoring.

I have always assumed that there is a live monitor output processing chipset for 720/1080 that does a reduced precision decode and scale process separate from the R3D data writing stream. If true, why RED has not updated that with a 2160P UHD/4K chipset is unknown.

In my Weapon CF I can author UHD ProRes, decoded and scaled from the RAW to RedMags internally, so the processing muscle must be there. What I don't know is whether that process would introduce too much latency to support a live monitor tap.

I assume that RED would like to offer a UHD/4K monitor tap on their cameras. Since they don't, I figure there must be a good reason. The fact that they have never directly addressed the issue may have more to do with competitive realities, than willful obfuscation.
