HDZero with ELRS backpack feature to be available in the new HDZero VRX module and the HDZero goggles:

Improved onboard DVR recording on the HDZero goggles has been confirmed via the HDZero Discord: https://discord.com/channels/88078299900...8606541824

“The new google has a new DVR SOC”

Quote:4ms optimized glass-to-glass fixed latency

If the refresh rate is 60Hz we get 16ms just from that.

Quote:1920x1080p 2000 nits OLED

Screen's resolution may be nice, but since there is no way that much data gets sent with fixed latency I am not sure how it matters.


I want to get into FPV but it seems to be an especially bad moment to purchase goggles. DJI still seems best for newcomers but maybe if I wait a superior product from a company that actually cares about the community will come out. If I understand correctly, nothing like this will happen - this will look like the HDZero we have today just on goggles with nicer specs - please tell me I am wrong.

Things change so fast ... until they don't lol. I'd honestly just get whatever your gut (and wallet) tells you. Personally, I've found my own sweet spot with HDZero. On the other hand just saw a pair of DJI v1s for $350ish on RCG so might be some good bargains out there.

The 4ms glass to glass fixed latency is based on the signal being directly sent to the OLED screens rather than via a HDMI chip. 

They have also mentioned a 90Hz refresh rate option in the Discord discussions.

With regards to the 1080p question, this has also been responded to in the Discord discussions: "We can use upscaling filters and make it look even nicer. Also, there is 100% a 1080p mode coming to hdzero". 

Will it look like the HDZero we have today? 

At this stage its all speculation based on the info they have provided for the upcoming HDZero goggle. 

Although the specs on paper sound awesome, we will only know when we see a final product available to the public. 

I cannot advise anyone to wait for the HDZero goggle because we have no real release date which could be mid year or end of the year. Its their first goggle, several new features, testing, production, chip shortages, lockdowns around the world?

If you want to fly today then buy what you can today.

In addition to what kafie said, also don't forget that the 60Hz is for a full screen/frame refresh but due to the way that HDZero sends data to the goggles and doesn't refresh a full frame every time it means that it's possible to get latency that is lower than the screen/frame refresh rate, especially if you are also bypassing some of the circuitry and sending data directly to the screens.

The following video by Chris Rosser shows some scientific latency testing between traditional analog vidie, the DJI FPV System, and HDZero which is certainly worth a watch if you've not already seen it...

The 4ms latency topic was recently discussed on the discord recently:

https://discord.com/channels/88078299900...2439066624

Quote:the full image latency is still up to 20ms. 4ms is the offset to the image latency that is measured with a photo diode test
the only way to make the full latency smaller is to increase the framerate.

https://discord.com/channels/88078299900...9253789696

Quote:4ms from the time the pixel is read on screen to the time it shows up on the goggles.
It still is only 60 FPS, so it will still take at least 17ms on average from the start of one frame to the start of the next.
the 4ms number means that if you lit up all the pixels on the camera with an LED, the first pixel to show as lit on the goggles would be 4ms after the LED was turned on.

LOLLLL good one

Here is a sneak peak of what the HDZero goggles are going to look like...

Looks promising.
I'm interested to get this to replace my HDO2/Rapidfire+ Sharkbyte VRX as I still need analog google ( Fatshark Dominator is out being digital only and not compatible with Dji Air Unit/Vista) and the new Hdzero 1s VTX lite / nano camera can improve small micros/whoops fpv experience.

HDO2 inability to scale 4:3 HDzero Micro V2 video and its crappy DVR are real negative.

Just decided to post the static images here rather than having to watch the video:

PS: We can still see some 3d printed imperfections but these will be addressed in the final moulded shell.

Plus the known issue with the HDMI input board on the HD02's (especially ones from later batches) which seems to go faulty, if not initially then some time after you start regularly using it for HDMI input. Loads of people have needed to have the HDMI board on their HDO2's replaced, and some people more than once. So it's probably better to use anything other than HDO2's if using the external HDZero VRX module.

Unfortunately when I turned in for the night only the video was available because they'd decided to launch the goggles tease via some weird audio discussion on Discord.

They look a bit more "boxy" than I was expecting but as long as they function and perform as intended then like with the DJI alien goggles it really doesn't matter what they look like when you're flying. The analogue module bay also looks like a bit of a clunky afterthought and very SKY030-ish, but it's better than having no analogue capabilities at all.

Carl also put out the statement at the bottom of this post to accompany the public showing of the HDZero goggle design. 90Hz 1080p OLED screens suggest that they are probably using the same display panels as the new FatShark Dominator / WalkSnail Avatar HD goggles because there are only going to be so many options available in that form factor.

No FOV is specified but the FOV of the Dominators / Avatars is 46° in a 16:9 aspect ratio, so with side cropping bars a 4:3 aspect ratio FOV will be something less (someone else can do the maths).

EDIT: Anthony Rivera (HDZero test pilot) has confirmed the FOV to be 46° (Source on FB HERE).

I want to set expectations about release date first. The goggle will be ready for a small group of testers in the June/July timeframe. General availability will be around September/October timeframe. If you have a set of goggles with HDMI input, I recommend purchasing the HDZero VRX now – don’t hold off flying HDZero all summer!

Whether you fly HDZero or analog, I’m confident that these will be your favorite set of goggles to reach for.

• On/off sliding switch – be confident that the goggle is on or off at a glance or by feel
  
• Designed for open source, the new goggle runs Linux. All code for the user interface is new and will be open source
  
• 90Hz 1080p OLED screens with sliding IPD adjustment and dials for focus adjustment
  
• By integrating the entire goggle display pipeline with HDZero’s fixed-latency video transmission, these goggles achieve 4ms glass-to-glass sub-frame latency with no jitter or dropped frames
  
• Mounting rails for patch antennas or whatever else you might want to mount
  
• Recessed front SMA jacks so you don’t have to remove antennas when packing the goggle away. Whether you install stubby antennas or TrueRC slide on patches, setup and teardown will be fast and easy
  
• Three independently addressable fans work in combination to cool the internals and prevent fogging. They are soft mounted to prevent screen vibration and noise
  
• HDMI input so you can use a ground station receiver, use for simulators, on the go movies, etc…
  
• HDMI output so you can share your video feed to others
  
• 3.5mm combination headphone / microphone jack so you can listen to analog or HDMI source audio or use a high-quality microphone for the pit-mic feature
  
• 3.5mm analog video/audio input for use with ground station inputs
  
• Analog input solves the vertical jitter problem found in analog OLED goggles today by using a 2D deinterlacer that adds no delay. This might be the best looking analog goggle display, despite it being a digital goggle
  
• ELRS backpack support so the goggle can automatically follow the channel of the VTX
  
• Add-on side-mounted analog module bay that accepts most of today’s analog modules
  
• Add-on 2.4Ghz WiFi video streaming module to live steam your flights
  
• Swappable faceplates to support different shaped faces and prevent light leak
  

Thank you,
Carl
