I'm trying to figure out which is the BEST camera to get, regardless of price? I assume the BRIO is the better of the webcams that are suggested, but would a 4K GoPro be better?
Has anyone found a relatively inexpensive way to make or buy a headcam?

From what I understand from the discussion thus far, FPS is more important than resolution, so I don't think the a 4K camera would be advantageous.
EDIT: Here is some discussion about resolution and FPS: https://forum.reallusion.com/343142/Tracking-FPS-really-low.
I would suggest going through the various threads as they contain useful information based on user experiences. The Logitech 922c is getting positive comments, so it's not always the most expensive that's the best..

Thanks. I'll take a look. One thing I noticed is that the GoPro Session 5 has a 1440P60 mode, but I think it's FOV is quite wide, which I think might be another factor to consider.

If you want a webcam I don't think you can go wrong with the Logitech 922x (which is what I have).
You'll easily get 60fps, which is all you need, and you can get it under almost no kind of lighting (I just have a single overhead light "sort of" pointing in the right direction). IIRC, Freerange said the Logitech cameras was what they had the best results, even including MUCH higher priced (and higher res) ones.
Note that while you can *technically* get 90fps with the Brio, in point of fact it's almost impossible (in reviews most folks said the only way to do it is outside, because you need insane amounts of light).
If you have Amazon you can order it (for less than $80) and if you don't like it, return it (which is what I did and I couldn't be happier). Incidentally, I have tried the GoPro (I own one) as well as a couple of my $$$ SLR cameras (one of which DOES do 120fps) and didn't get any better results (and they were such a PITA I won't do that again).

Thanks for the info. I played with the trial last night, using the webcam on my MSI laptop (30fps), which was adequate for testing. It did give me the impression that a Headcam would be best, and I have two perception neuron mocap suits, which I intend to use, so I'm thinking that gopro is probably the best choice. However, I would still like to know if the logitech actually provides better results.

I have no problem tracking at 90 fps with the Brio, but I have many windows in my studio. At night , it is a different scenario and I would need to add an overhead diffuse light. I ask Brian from Faceware Technology , a question about tracking in 90 fps, here is my question and his answer in case it might help others.
Hello Brian,
Just a quick question. At the moment, with the Logitech Brio, I can run Faceware realtime for Iclone at either 60 or 90 fps. Now we both know that Iclone record only at 60 fps. Since I have both options and Iclone seems to be playing the captured motion at the right speed with both fps options, Should I run Faceware realtime for Iclone in 90 fps or 60 fps to have the best capture motion? I have a M.2 SSD and a fast computer. I have the feeling that when choosing 90 fps, the faster lips are handled better but I am just wondering what happen between both softwares when converting from 90 fps to 60 fps. This info would be valuable to me and other Iclone users.
If your scene in iClone is running at 60fps, you shouldn't see an appreciable difference in the end results on the animation side between using 60 and 90 in Realtime for iClone. You are correct, however, that using a higher frame rate for the tracking can help with the accuracy and would help to prevent the tracking from falling off, as the increased frame rate results in less motion blur and more updates of the tracking data.

Well, that is some interesting feedback. I've seen people complain about the BRIO, but maybe they just don't have it set up properly. Light is clearly something that needs to be considered for this. Has anyone found a cheap LED lighting panel that they recommend?

It would seem higher than necessary frame rates and res would only slow performance or accuracy, just an opinion I've only used several cams.

Yeah, I tried a couple of cameras with frame rates as high as 120fps, and saw no improvement over 60fps (but 60fps IS the way iClone runs, so it makes sense that it's the most optimized for it).
As Brian from FW said, the only real advantage of higher rates is it might not lose the tracking, but I've had no problems along this line at 60fps unless I move my head too far.

Ordered a couple of these but haven't received them yet:

Would love to know how it works. What camera did you get it for? I see they don't have it for the GoPro Session 5, which is what I would like to use.

Bought them for our Samsung Galaxy S6 phones. We also have our old Motorola Razr Maxx HD cell phones but figured these would have better frame rates (but never really checked). And I mainly wanted them to help me design and build one if need be.

The Logitech BRIO Ultra is a dog. I can't get it to track at more than 40 FPS; the options software from Logitech doesn't recognize that it's connected. I'm returning the device and ordering the 922x, which is less than half the price. I'll see whether that helps.
Any suggestions on alternate cameras would be valuable because Logitech is NOT a high quality company, based on the reviews it gets. The BRIO in particular is getting slammed.

Before you return the Brio, you ought to try using the Logitech Gaming Software (a separate download) to turn off low light compensation, which is a reason for many they can't track higher. That and making sure you've got optimization turned on in the FW plugin ought to insure you easily get to 60fps, if not higher.
I love my 922x, which is a solidly built camera and gets me 60fps with very poor room lighting. But, again, I need to turn off low-light compensation, and run optimized in FW. But it does appear that higher tracking rates won't help much anyway, so it's more cost effective than the Brio.

I just read the logitech forum and it seems like the logitech gaming software is not compatible with the brio.
My Brio works fine and there is another forum member that just solved his problem yesterday. (He updated his usb driver)
Just to let you know I have absolutely no problem with mine. I am getting 90 fps without a hitch. I had a little problem to get more than 15 fps at night and solved it today placing an old diffuse lamp light in front of the Brio (In my back) and I now have 90fps even at night with no exterior lights.

For those with a Brio who need it: I'm just downloading the Logitech Gaming Software, and the latest version (from 8/21/2017) adds support for the Brio.

I ended up getting the 922x because I wasn't interested in dealing with the BRIO problems that others were having. of course, it seems like those may have been solved. In the end, I will probably get a GoPro and build a headset as I think that will be the best solution. I'd like to find the headset helmet and arm that faceware has, without the camera and HDMI transmitter. $2500 is a ridiculous price.

Did I post the link here or in another thread to that helmet cam a guy built out of a bicycle helmet and parts he said cost less than $20? If you can't find that link, just Google it and I'm sure you'll see it (I just need to find my bike helmet :>).

I tried to do an helmet myself last weekend. I had a bicycle helmet and a construction helmet. I feel that even with light components and a webcam the helmet tend to pull from the front. That's why many put a weight in the back. But I decided that's it's not worth it, it is to heavy for a serious actor.
For now, I will stick to the standalone webcam in front of the actor. The tracking is quite good even if they move a bit and this will be a much better experience for them. On top of that my audio recording booth wasn't build for body motion capture, so I prefer to do it as a second step process.
Directing the actor to have the voice you are looking for and capturing the facial motion capture simultaneously is already great for me.
Eventually, I will buy a real facial mocap helmet.

I've tried two different webcams. Both of them don't go higher than 15 fps. At first I thought it was because I bought a cheap 35 dollar webcam. So I ordered a 75 dollar one and it has the same problem. The 75 dollar cam arrived today. It's the Logitech 925 e. I'm doing a fairly low resolution, but so far no matter what the resolution is set to, the framerate drops from 30 to 15ish in about a second or two of starting up Faceware Realtime for iClone.
Any suggestions?
