Video Chat -- Who Has the Best Quality Picture?

Milo_Mindbender asks: "There are lot of PC based video chat programs out there now, but every one I've tried lately seems to have pretty low-quality video even when both participants have cable-modem and high quality USB2 or Firewire cameras. The recent 'Windows Live' update was advertising better quality video, but it doesn't look any better to me. Now, I'm asking the Slashdot crowd: of the programs you've tried which ones have the best quality video? I'm mainly interested in low-cost or free Windows PC solutions, but for the benefit of all the readers maybe we could come up with 'best Windows', 'best Mac' and 'best Linux' recommendations?"

iSight with iChat on Mac

[zygote]

I think the iSight (non built-in) generates a pretty good image. It has a rudimentary auto-focus and handles less than optimal lighting.

The amount of compression applied -- which I imagine is a product of the bandwidth available -- is probably a bit factor in image quality as is image size.

The camera built into the MacBook, iMac and Mac Book Pro also performs pretty well.

All in all, like everything else, there are alot of variable that will affect your mileage.

I definitely agree, iSight w/iChat is the best. A few months ago for Mother's Day, I set up videoconferencing for my daughter's two grandmothers, we're spread out across the USA. I tried MSN Messenger, Skype Video and iChat. iSight+iChat was *so* superior to the others in terms of picture quality and video quality (slightly different considerations) that I ended up upgrading my Powerbook to a MacBook Pro, giving the hand-me-down to my parents, and setting up my in-laws with an iSight for their Mac Mini computer they were planning on getting rid of. The quality is simply in another class from the other solutions, in my experience.

iChat with a DV camera also tends to work really well. A big advantage of a DV camera is a big lens and manual controls. Instead of having to trust the iSight's auto white balance and brightness (or use iGlasses) you can manually set what you need to get a good shot. A DV cam with an IR remote also works well when doing presentations or group chats where you might want the camera to zoom in on the frame sometimes but zoom out to emcompass everyone.

The thing about iChat is that it uses H.264 compression, which gets more quality for a given bandwith than MPEG4 and similar compression. Any chat system should perform better using H.264 (if the host can handle it).

Check your setup and conditions.

[Anonymous Coward]

Any camera won't do too well in if the conditions you're shooting in aren't good. Good lighting, no backlighting, and a full view of your face (for focus) will have a larger positive impact than whatever program you're using. More tech doesn't always work as well as good composure.

My Personal Experience

In my my previous comments I mentioned trying a number of services after getting my family webcams.

We now use MSN 7.5 (pre Live) quite successfully. It can switch to full screen, which helps considerably when there are people gathered round the PC to chat as a group. Occasionally have trouble with something locking up, but restarting the video conference usually fixes it.

I tried a number of services with my brother in another state before deciding on MSN. Skype had just released a beta of their video service, and the video quality wasn't quite as good. Yahoo didn't have a good update rate. I didn't try AOL which seemed to want to install much more than a chat client. There were a number of clients like ineen, so similar that I swear its the same software with different skins for different markets. All had tiny video.

After trying all of these I realized how important it is to keep the audio in sync with the video being displayed, and to degrade in a manner that is easy on the eyes. MSN outshone the others in this regard. (Talking on the phone as we start the conferences, you can really notice the delay imposed to keep the sync. But after we're just talking on the PC, its much more important to keep the audio in sync than to reduce the latency.)

MSN all the way

[Donniedarkness]

I'm a soon-to-be college student (very soon-- next week), and I wanted to buy some good webcams for my girlfriend and I to be able to see each other with.

I looked around at some programs to determine which would be the best (I did, after all, just spend $130 on the cameras). I really wanted to like Skype, but the video didn't seem to go very smoothly and the quality wasn't so great. Also, it didn't show the full range of my camera (it cut off the edges on the sides), which produced a "zoomed in" picture. Yahoo Messenger just sucked, period, and I refused to use AOL because it wants to install other crap with it. I've also never liked the look of it. I was cursing Google for not including a video-chat function with Gtalk (which is by FAR my favorite messenger. Nice, sleek, and not annoying).

As much as it pains me to say this, I chose Microsoft's chat solution. Windows Live Messenger has the best, smoothest, highest-quality picture of any of the programs I tried. The audio also synced up nicely with it. I say MSN all the way.

Get CAMFROG

[Khyber]

It comes in Windows and OSX flavors (With *MAYBE* linux support coming soon.) I've used this EXCLUSIVELY for the past few years, and in many of my other comments and journal entries you'll see mention of this program. This program is good enough that you could (with enough bandwidth and proc power and RAM) watch 100 people at once doing sign language as fluidly as real life. It's that good. Only downside, you need to pay 50 bucks to be able to do most of the kick-ass stuff in Camfrog, but it's probably one of the only programs I've paid for. The server software is $200 dollars, and you can restrict access so tightly without the need for MAC banning (thru a ban/allow list you can edit in text editor of choice, so you can first block out the net, then only allow people in by nickname.)

You will be pretty floored by how well it performs for such a small program. Also, the current OSX version is BETA, so most internal cams on newer notebooks will not work at all. It's smaller than most good V/V chat programs out there (3.6 or so megs for windows, 5.6 for OSX I beleive.) Try it. It's compatible cross-platform. Mac and Windows users can chat with each other, and when you have broadband, it's sweet. I give guitar lessons live thru this program, to a nice 100 people at once with a decent server. Let's see iChat do that with 100 people at once.

Enjoy. There's rooms for everyone/type out here. Just watch out from idiots from Turkey, Egypt, and most of the Middle East. they're all pervs and will ask anyone for sex, or will pop into a room and randomly start whacking off. Thankfully *MOST* user-owned rooms have moderators (sadly a pay-for only feature, email the guys over at Camfrog and let them know what features you'd like in this program before you pay $50 for soem decent damned software!)

Don't mod me down for advertising/shilling for these people. I'm not paid by them. I'm a very impressed customer. And anyone else talking about ANY other program is advertising as well as I am. Be hypocritical if you dare.

Re:Get CAMFROG

[Perseid]

Camfrog is okay. The image quality and frame rate are actually quite good. But it's more for group chats than one-on-one sessions like most chat services are. If that's what you want, look at camfrog. If you want to webcam chat with your brother in law in Florida every so often, Camfrog is probably not the answer.

Also, the signal to noise ratio in the larger chat rooms is terrible. As the parent said, dozens if not hundreds of people from what appear to be various muslim countries flood the English-only rooms with foreign languages and broken english asking every female cam they see to "open tits" and whatnot. IMO this makes the larger chat servers unusable.

And lastly the free version is quite crippled. So Camfrog is an option, but be sure to try it out for free before you give them any money.

Re:WebCam is the more likely suspect

[Myself]

Agreed, it's probably the camera. The compressed image will never look as good as the original, so if the original is just barely acceptable, the compression has a hard time telling important details from discardable details, and the result will be unacceptable.

Most cheap camera sensors are horribly hungry for light. Fix the lighting situation first, and see if the problem goes away. Then, look at a better camera. If you can post a 640x480 snap from the camera on the web, and have people click on it attempting to load the high-res version because they assume it must have come from a nice camera, then you can start to blame the software.

While doing some research into USB cameras a while back, I found a few recommendations for the Vista Imaging Vicam USB. That's to distinguish it from the parallel port version: This sucker was designed back when cameras were curiousities for the rich, and no expense was spared. It's built around a beautiful quality CCD. It's sold as the 3Com HomeConnect Camera, also the InsideOut Networks / Digi Watchport/V. They're all the same guts, and work with the same drivers.

I picked one up at a flea market for $5 and I'm impresed. The stills are incredible, and it's sensitive enough to produce really useful images in candlelight. (Just don't move; in low light it can take a good fraction of a second to gather a frame's worth of photons.) The design is thoughtful, too: The included tilt/swivel stand is attached with a standard 1/4"-20 thread, so removing it readies the camera for practically any mount.

PC Magazine Thinks SightSpeed is the Best

[dannyastro]

http://www.pcmag.com/article2/0,1759,1979143,00.as p From the review: "Bottom Line: Hands-down the best free Internet video calls offered by any Web service. You'll be amazed at the video quality and tight synchronization of audio and video when using a broadband connection and 30-frames-per-second webcam. Pros: Phenomenal video quality. Unlimited free video calls, video e-mails (up to 1 minute with 30-day storage), text messaging, and voice calls to other SightSpeed users. Windows and Mac support. Low-cost calls to traditional landline phones. Voice-only calling mode. Cons: The expected beta hiccup in the interface here and there."
