I am considering upgrading my Dom V3 tot he Dom HD3 but all my cameras are 16:9. How does the HD3 treat the 16:9 image? Compress, cut-off or what?

Thanks

the Dom HD3 switch to 4:3 when using with analogue as far as i know, and it only switch to 16:9 when using HDMI port...
So yea in your case the image will look compressed.

Yep, I have the HD3 and can confirm that.

So the HD3's display all analogue video in 4:3?

That's kind of dumb. It also makes me very glad that I decided to get the Skyzone SKY02S goggles when I was looking for an upgrade from my Fatshark Predators.

The Skyzones look great with a 16:9 camera! With a 4:3 camera of course, they end up stretching the image to fit, but I can live with that.

  Good freaking grief. How does Immersion keep getting this wrong with their goggles? Seriously? Why can they not seem to be able to develop goggles that adjust to the camera ratio. It's not that freaking hard to code....Even if all they do is grab the middle of the 16:9 image. I would actually like that in some situations. Sometimes 4:3 is a good aspect but they tie you into one thing or they destroy the image.

Makes me wonder. Are their code monkeys in China or are they in USA, EU or Aus?

I was looking for an excuse to upgrade my goggles....

Actually, it's much harder than you might think. There in nothing in an analogue TV signal that actually tells you how many columns there are in each line of the signal. In fact, a TV signal only consists of lines, there is no such thing as a column at all.

There is a later standard that allowed broadcasters to add extra digital data to the TV signal to tell the receiver what the intended aspect ratio of the signal is, but the TV signal that our FPV cameras generate does not include that kind of information and neither do the receivers detect or understand that extra information.

What Fatshark and others should do is let the user tell the goggles how they would like the signal to be displayed, but I don't know of any goggles that have that feature.

Would be pretty easy to allow the user to choose though, specially since the 16:9 capability is already implemented for when you plug an HDMI source.

My point exactly. Just let us choose in the menu which aspect we want without compressing the image.

I see no reason the user could not choose the display lines in the menu based on the camera. Instead of compressing the image and distorting it just default to 16:9 like the V3 and then turn off the other lines for 4:3. Why would this not work? Particularly since the display is already made to switch. Analog signals can be converted for display purposes why not in this case? That would be a much more elegant solution. When displaying the image signals on stand alone LCD's there does not seem to be a problem with doing this without gross distortion.

I would rather pay $500 for a set of goggles with these features than deal with all the myriad Fatshark versions which just don't seem to make sense.

There's nothing to stop the manufacturers adding a function that would let you choose. It's just that none of them seem to have realised that we would like it!

It's only doing it automatically that's hard.
