Just need to go the other way now too. High bandwidth mode that spans 2 channels for higher quality. E.g. 1080p60 for the other cameras. Would then have the complete package. Great to see the continued development regardless
The only thing I wish HDZero had is on-quad recording, like you get with WalkSnail. That would compensate for the breakup while retaining the HD video, without needing an action camera.
Long range mode looks solid, but would be great if the system could drop the resolution (and maybe also to b/w) automatically when the VLQ drops to 0.
Agree, I think having an option for automatic switching would be ideal. That way you could opt in to that behavior, or keep things the same as they are today
That can't be done with HDZero by itself, but you maybe able to use ELRS backpack functionality to achieve that? Would be interesting to implement this on the HDZero goggles...
My camera has to do like a reset when switching modes right?
Wouldn't be possible in flight if so
I learned how you put a lot of those miles on your e-bike. Testing firmwares... lol Good overview Ryan, I've been testing a little myself and see the same types of behavior. Exciting that still years later, we're getting new feature for existing hardware from Carl and the HDZero Dev/Engineering team.
Thanks for the update. When freestyle vtx v2 release?
Cuddos for the water content of the beton thought, reminded me of my uni years in civile engineering
Great info, thanks! I'll definitely give the new options a try.
HDZero keeps improving! Thumb Pro tutorial would be great. Thanks
Great overview! Just started testing this stuff yesterday!
Honestly resolution isn’t that important to me, 540 seems perfect honestly, 720 and 1080 doesn’t really help me in any way, I feel 🤷♂️ whereas 90Hz DEFINITELY helps me!!! Should flash/build some more 90Hz cameras!
A 90Hz whoop camera would be amazing!!! The nano camera is WAY too heavy, but great for what it is!
Would love to see 540 not get scaled to 720, and just be fed RAW, pixel doubled, to display, very curious about that… I assume sparkles will be larger, but I’m curious to try it.
The more I see of this, the more I am certain HDZero is the future. Screw DJI.
Thank you, some things must be said. 👍
DJI is like the spoiled kid with all the expensive toys, but he insists on having control over everything we play, HDZero is the good friend who works with you to find the most fun stuff to do together.
The future is going lower and lower bandwidth and still having static?
@ clueless
@ I would say it is, for me a great direction forward, because, there are options opening up for the end user to change and customize to their own liking, and specific need.
Love what you and HDZero are doing! Cheers!
Thanks!
All of this is just awesome. Hdzero is so cool man. Great vid Ryan, thank you
My pleasure!
Are there any antenna that are made for that low band?
Wouldn't using normal 5.8ghz antenna be inefficient on L band?
great test. Ive been meaning to compare it but never got around to it. thanks
Glad to help
Thanks for this test
Would be nice to have dynamic switching to narrow bandwidth in low signal. All of these look like returning to analog, but with more expensive vtx/vrx :)
Not possible with the VTX alone as it is a 1-way comm channel, not 2-way bidirectional like DJI/Walksnail, so no way for receiver to send SNR data back to the transmitter. But they might be able use the ELRS backpack as a back channel to the VTX (via MSP to FC, via ELRS RX) to send the SNR data to do dynamic power output. 🤔
GREAT VIDEO BROTHER!!!!!!
Ryan, I appreciate you, sir.
Thank you, I'm a big HD-Zero advocate!
Carl is terrific!
👍
Very welcome
This is great. 👍 Very excited to try it out. How long till that new 1W VTX comes out is my question? I need that in my life I think.
Personally these new features are really only for racers . It's all good but don't forget about us freestylers HDZERO.😁
Nice video🎉
Love that low band. Will that cut out all the dang DJI interference when flying with my group?
We need a mode for hdzero where instead of the static blocks being random color like analog, the blocks should show the data from the previous successful frame. In other words, if the data is missing for that block, show the last known data. It seems like this would make the image look much cleaner.
Edit: Would be nice to be able to adjust the threshold for this as well, where you could control the % of data allowed to be missing before the image is lost. EG: 30% would mean that once 30% of the data is missing the image would revert to static looking pixels to let you know you're losing signal.
For some people, that might be helpful. For you, it would be a benefit. But for me, I find that the sparkles are something that my brain leans to ignore, and I am able to see through them, kind of. But if previous data was displayed in place of the rainbow sparkles, I have a felling it would throw me off, and make it more difficult to respond to what is actually in front of my camera. (I fly a lot of fast proximity stuff - I can see how flying at altitude, or in open environments, your idea may be a more pleasant flight experience) I love your idea of being able to adjust to taste. If that were to become possible, we could have an on/off to tell the system to either show sparkles, or show previous data, if (on) then: adjust %.
This is probably my favorite part about HDZero. There are so many thinkers, and problem solvers in the community.
Also, a feature request. it would be helpful if the goggle menu had the stick commands in it. As a new user, I don't have them memorized yet and that would be the perfect place for them.
That looks like a super feature for the LR guys. Though there is not much penetration difference btw 60 and 90fps. Hopefully 540p90 on Low band will be ok for the bando. Specially after the new 1W VTX teaser
Maybe it would be also worth looking into combining two channels to get more data throughput. I'm quite sure I heard an interview where Carl talked about that.
Super cool that were getting lowband channels!
Do you know if it would be possible for carl to change the static pixels from the "rainbow" multi color to just be black instead? I know bardwell brought this up in a video some time ago but i never heard any response as to if it was possible. Im colorblind and im sure this would make interference much easier to fly through because the actual image wouldnt blend so easily with the static.
I'll ask
@@RyanQuellet thank you! 😊
Grayscale instead of color would make it easier to ignore, all darker shades as well so it doesn't make your pupils contract.
This would be great. Being partial colorblind, I already prefer HDZ breakup to the blurring of DJI/ws systems, it's just easier to know how bad your signal is, especially when flying in difficult areas. If the pixels were black or just grey it would be even better!
I wish there was a way to use 2 channels at once for more signal. Like R1 and R2 together. Fewer pilots at a time 8>4. Maybe linked or not. Would definitely give more options.
Would be cool to run 1080p60… unfortunately breakup and signal stability would be exponentially worse… I don’t see this working out… people already complain about the current breakup 😜
@@lemonsquareFPV not by doubling the bandwidth
Im amazed by the hdzero system! Which hdzero camera/vrx do i need to try 540p60?
Could help for indoor racing . Nice 👍
Great point! I intend to try this for some indoor racing this year
@@RyanQuellet is it on the 26062023 firmware ?
Hey Ryan, do we need to change the bandwidth to narrow in the goggle menu every time we use 540p60 mode to see the benefits of the lower resolution?
Range testing on lowbands next? Should physically be able to go further. 😁
I'm not much of a range junky, I hope someone else does though!
@@RyanQuelletLR wing is ready for the test, only the weather isn't 😅
@@RyanQuellet it would be nice to see how much better it performs compared to what you already showed.
Definitely curious about your Thumb Pro settings.
Darn. It requires the nano 90 cam. I was hoping it was just firmware :/
I’m a standard guy. I might for longer range use the new mode though.
I’d also love to see your work flow with the thumb pro.
YES PLEASE! @Ryan Quellet a bit on your workflow with the ThumbPro would be nice. I am assuming GyroFlow, but do you have any secret sauce settings?
Is it possible to switch 'video mode' while in flight? ( for instance with a switch on the transmitter? )
Great Video.. Is there a vtx table that would include the lowband channels, or do I have to build it.
Lowband is in the Utilities section of HdZero's Firmware Page. Same as the 1-Watt Unlock. Same procedure. Load the Lowband Unlock firmware, power cycle the VTX, then load the regular VTX firmware. If you're looking for more detailed instructions, you can find them in HDZero Wiki. (don't forget to use a fan), while VTX is powered on the bench, it will get hot.
Will the Lowband channels increase reception quality?
I’d be curious if it’s possible to take the 27MHz bandwidth and chop it up into segments and then spread them out.
Was the whoop vtx on a Flywoo Nano baby?? Those guards look familar. lol ... good info - thanks.
Yes, I put the nano 90 on my flywoo nano baby 20 - love that quad
That is great. But I would love to see the HDMI input issue fixed. Making such advances and neglecting the most basic functionality is awkward. And would be nice to have a superlight 90fps camera like the lite one.
Does low band also work on the 1s whoop vtx?
So its confirmed that the new vtx is 1watt. 😊
My big question is how to change resolution. I'm stuck in default
Does this work with the vrx?
Great Video, Love my Goggles! What's the point of Low Band if average Joe like myself can't use it! I've tried, didn't work! Still love my Goggles Though! Thank You
Exactly what "special license" is needed to use low band legally in the USA? Is a technician license for Amateur Radio sufficient?
Low Band is outside of the ham radio frequencies. You would need some sort of FCC experimental license, which is fairly difficult to go through.
For some reason the 540p@60 has a lot of break up with my Sharkbyte vrx. 🙁
Hi Ryan, I’m having trouble. When I am in 540/60 my sticks won’t allow me back into the camera settings (throttle Center and hold right) so I can’t get back to the other camera resolutions!
Any suggestions?
Try flashing vtx firmware again
Hi Ryan,
Yes that worked.
I am concerned now that if I changed it out in the field I would be screwed unable to use the stick controls and be locked out. Is it work passing the issue on?
I have been dealing with Goa a fair bit from Divimath is it worth me letting him know perhaps?
Is the 'car park' an instance where 1 LHCP antenna might help?.. As that's what you'd want for reflected signal?
Good idea
@@RyanQuellet well, it was your idea in an earlier video, I was just posing the question as you didn't specify when the LHCP antenna would be useful.
Would honestly be super nice if there was a way to change modes with a switch. Fly 720p60, realize you're losing signal (or have Betaflght check your RSSI?), switch to 540p and continue flying. Maybe even have a few even lower resolutions?
I was thinking this too. Maybe a switch on my radio that uses ELRS backpack to change goggle and vtx to 540p60 for a short period
@@RyanQuellet the breakup from the vtx while changing looks like it take a good full second though, no ?
@@metalfpv could be as short as 0.5 sec. Would have to see
Can’t wait to give it a try. Hopefully it will be the penetration I need to chase my friends on mountain bikes through the woods. I want to get rid of the dji goggles 2 because the goggles hurt my face so much.
Could be what you need. Just one more know you can turn if needed
Hey Ryan
You have anything coming out on the freestyle V2?
Yes. Soon
@@RyanQuellet great I’ve just put one in basket on pre order been trying to find some info on them. I’m making the switch Thanks
@@RyanQuellet hey again, also, now that the goggles have been around for some time is there any movement on a V2 goggles coming?8
Is low band support slated for the event vrx ? Someone asked the question in the hdzero discord and I think the current answer is "no" but could use an expert to weigh in on roadmap. If low band is to be adopted for racing (to allow more / simultaneous racers?) but not supported by event vrx, it may stunt any adoption to that low band (for racing).
Yes, low band will come to event vrx
how about lowband on the event vrx? :)
That's coming
07:40 - switching to 540p60 in osd menu
is this mean 540p the only way to go at the moment for hdz to increase penetration and range with less breakup?
Unfortunatelly 540p is not HD
Ohh my god, I found out why my Freestyle V2 doesn't work atm. I changed it to 540p60fps and I lost video. After that I couldn't regain feed. When I put my HDzero Goggles to the narrow mode It worked again, so I could change everything back to my normal 540p90fps. I'll leave this comment here so this hopefully can be useful for someone :)
Keywords to find this comment: Freestye V2, lost video, feed, video mode, blue light, red light, Crux35, bricked.
Let me guess….the nano 90 doesn’t work with the vrx4 either🤔
too bad that it only works with the Nano 90 when have much nano lite or v2s
Try To 1,2 Ghz
Yes! But not much bandwidth there.
Nah. The 720p looks bad enough so I'll stick to that. If I ever feel like flying with worse picture then I can just fly one of my old analog setups with a beefy vtx.
It trips me out that someone can look at the 540p mode and say with full conviction that it looks as bad as analog.
You qualified to make assessments of how much water content their is in cements? Honestly one of the stupidest claims I've seen in a fpv video.
There is water in your head as well.
