The new HD Zero Micro V3 camera to other popular systems like DJI and Walksnail. The Micro V3 camera boasts a native resolution of 1080p at 30 frames per second, with enhanced anti-aliasing and image quality in standard resolution mode. With a larger lens for reduced vignetting and improved low-light performance, the camera promises a superior experience. However, it does not support flying at 540p at 90 frames per second like its predecessor. The 3-to-5-inch build range makes it ideal for most setups, while the Nano V3 camera is more suitable for smaller builds or whoops.
During testing, the standard resolution mode did not make a significant difference in image quality. However, switching to 1080p mode revealed a bug in the goggles, impacting video smoothness. This issue will hopefully be rectified in a future firmware update. Despite this setback, the high resolution mode does deliver an overall improvement in image quality.
It's important to note that HD Zero operates as a one-way system, while DJI and Walksnail allow the VTX to repeat information, resulting in either more latency or a blocky image. When comparing the Micro V3 camera to DJI and Walksnail, we employed the respective setups for each system.
Moving on to discussing our FPV flight setups, I currently utilize goggles X with stock antennas and a Rush Cherry v2 on the quad. For HD Zero, I rely on the stock antenna from the Freestyle V2, TrueRC stubbies, and a pair of TrueRC X2 Air Mark IIs for the goggles. Although this is not a rigorous scientific test, but rather a quick flight test, it provided a glimpse into their performances.
When testing Walks Now, the image quality left a positive impression. Next up was DJI O3, which performed exceptionally well, meeting our expectations. In a side-by-side comparison, HD Zero stood out as a different system altogether, while Walks Now and DJI exhibited more similarities. To make a relatable analogy, it's like comparing a track-built car to a regular dealership car. Those seeking an FPV system that feels more like a consumer product might find HD Zero less appealing. However, for those desiring ultra-low latency and a more locked-in experience, DJI and Walksnail cannot match the capabilities of HD Zero.
To achieve that optimal experience, I recommend utilizing the Micro V3 and the Freestyle VTX V2. It's worth noting that the original Freestyle VTX is not compatible with any builds. To get a visual understanding of this setup, be sure to check out the video linked in the description. This is Darren Allitt, and until next time, remember to send it.

Its good that you touched on the difference between one and two way systems, but I think its worth going a little deeper. DJI and WS require retransmission because the VTX sends h265 compressed video. With compression like that, the loss of small bits of key information can lead to the rest of the information being useless. The whole point of compressing is removing data redundancy, so if you dont get everything, you often get nothing. Eg, h265 compresses by comparing frames over time and sending only differences to a keyframe. So if you didnt get all you needed from a keyframe, differences from that keyframe become useless information, and you get corrupted video for the next 50-100+ frames. This is why WS and DJI absolutely depend on retransmission. And if retransmission doesnt work the first time, they need to try again, and again which can lead to stuttering and freezing. HDzero sends uncompressed video, this allows the goggles to show whatever it is receiving, even if some or much of that is junk data. There is no dependency on old data, every frame is discarded after being shown, no need to ask retransmission just grab and show the next frame . This helps with latency but just as importantly for long range pilots, it allows you to reestablish a link instantly after you lost it , because there is no connection with HDZ, no handshake. With DJI and WS this may take several seconds or never happen at all.

@@baughaninastorm No one flies HDZ because it *looks* best. If thats all you care about, and you fly large enough quads, O3 is for you.

@@vertigo2893 I'm not saying HDzero doesn't have it's uses. Range, penetration and image quality are not in its wheel house. Putting a 1080 tag on a camera would seek to induce the impression it's gone to be HD. If I had the skill to race I'd probably fly HDZero. I genuinely hate DJI and I don't even see what other people see and that is that CADDX are somehow the people's champion. I just don't get an apples and oranges comparison

I have v2 and v3 vtx's. Also have several runcams including the 90fps. My best penetration has been with circular polarized antennas on both ends. I also have flat panels designed for RHCP antennas. At 200mw I'm more worried about losing control surfaces before I'm out of clean video range. Weaving trees is no issue ....

@vertigo2893
@vertigo2893 4 месяца назад
That assumes the receiver can differentiate good data from corrupted or missing data. Im not convinced it can. Also, you could only do that after you received/processed the entire frame, so I imagine it would add non trivial latency. If it is possible it would be nice to have the option, but Id probably keep it turned off if it adds a single frame of latency. Im more interested if it would be possible to have frame per frame compression (mjpeg style). That would have its downsides for sure, might also increase latency, create weird artifacts, but the decreased bandwidth requirements might provide significantly better range. That would be an option I might be interested in in some situations

@@vertigo2893 it can differentiate good from bad data. Cyclic Redundancy Check and Error Correction algos are a thing. But it won't retransmit. I guess if hdz could double the latency by sending the same data twice, but it's not clear that would also double the range.

@@cedricgrandseigne yes obviously, if your old family videos are on VHS. Similarly if you want to fly with a few friends, you will need to use narrow bands, lower power and/or "race mode". I use the latter on walksnail whoops for the reduced/fixed latency, it is useful to compare that to HDZ. Spoiler alert: its still worse on pretty much all metrics, quality, range and latency, but its more enjoyable than the high latency stuttering.

I enjoy the comparison to other HD systems. However, I am at the point of gearing up for FPV and really need some comparison advice. High-end analog or HDZero... ?? I need a system that is really stable and as clear as possible to 250 feet. That's all. But that does include working around a house. I have a 200mW all-in-one unit and Emax 800D goggles. I also have a 1200line camera and a VTX that goes to a watt. I'm ready to upgrade. Pricing HDZero looks like around 450 for everything if I go Emax HD box Transporters and a Nano V3 Lite camera and VTX. Must have light weight. Considering my modest needs, I wonder if the investment in HDZero is really worth it. 450 buys some fine analog stuff... BTW... I have no interest in posting video... just flying. 720p30 is fine. Kinda need box goggles, too. Opinions?
@Zillawill

@vertigo2893 4 месяца назад
Why do you need boxed goggles (and not adjustable diopter) ? Anyway i see some mixed reports on the transporter HD. Apparently it overheats and starts stuttering. Not sure if that is a universal problem or if it has been fixed, but be on the lookout for that, you dont want that to happen. In your shoes, I would either go for the "real" hdzero goggle if you can afford it, or get a (used?) analog goggle with a good module. Something like a TBS fusion really makes a lot of difference im both range and image quality and high quality analog really isnt half bad. I still use it a lot despite also having HDZ and walksnail.

With the Ratel2 this is no problem but I gave up on rhe WS. Am I to stupid to find the correct settings on the WS? Is HDZ better in the light handlinf / WDR?

@vertigo2893
@vertigo2893 4 месяца назад
It doesnt look as good as WS or DJI (if those have a good signal), but it also doesnt look all that shitty live. What you are seeing is the original uncompressed signal, encoded by the DVR, re-encoded by video editing and re-encoded by youtube. Before you say thats true for all systems, other digital systems transmit h265, the goggles dont need to encode it, just save it. And other systems dont have random noise, you cant compress random and that makes it much harder to re-encode sunch video at low bitrates. Analog has the same problem, DVRs and youtube look a lot worse than the original feed. Watch some raw DVR at least to judge it on. I expected to hate HDZ breakup, but in reality, the noise looks like snow on an otherwise perfectly crisp and sharp image. I find it easy to ignore and easier to deal with than analog breakup (which often distorts the entire image) or the pixelation and stuttering of walksnail. YMMV.

If you get a chance to fly it before you buy it, I want to suggest flying the Nano90 Cam. I started with DJI, and still fly it when I want to record a perfect sunrise, and not have to carry a payload camera. Or, since DJI gets better penetration, I like to use it to do my scouting. But after sitting behind the 540@90, that HDZero's Nano90 does, I tend to fly HDZero most of the time. The best way to describe the feeling, would be to say that it felt like I was sitting right behind the camera's glass. But those words would not have meant much to me, before I experienced it. After a few weeks, maybe a few days, of flying it, my mind stopped reacting to the rainbow sparkles, as if they are in my way. I just kind of see through them, if that makes sense. Now that I'm used to the sparkles, my brain perceives them like a visual beeper. They tell me that the video signal became weaker, and that information loops back into my sticks. I hope I communicated a clear enough picture of my own experience, that you might have an easier time deciding what's right for you. Happy flying.
