Just checking about the ATEM TVS

The only output that puts out H.264 is the USB right?

Yes and only on windows (unles they've changed it recently)

The usb 2.0 h.264 works on both windows and macs when you are recording with Media Express. It´s when you are trying to stream with it you more or less can't use it on a mac.

Thanks just what I suspected. Wonder why on earth they make such a big deal out of the H.264 then. The cheapest and probably best way to broadcast live to the internet today is by using a capturecard and let the computer do the H.264.

And oh yes you absolutely can use a mac for livestreaming with the ATEM I do but you need a capturecard as on Win. Im having a really hard time to believe that anything usb related except for a webcam can be fast enough for livestreaming.

So if somebody would care to proove me wrong please do Ive been wanting to get a chance to watch a cast with mxlight.

I can make broadcast for you next week with mxlight.. Its great .. It use x264 whitch is best h264 encoder..

Thanks that would be really great I have been trying to find a live broadcast or recorded broadcast with mxlight. I want to compare the quality in fullscreen on two of my flatscreen tv sets (47 and 55 inch) with what I get with the intensity pro capture card when I cast on youtube live.

If you could PM me when you when you will be on air that would be great. I can check back here in the thread too if thats better for you.

Thanks again.

(I have good i7 PCs too so I can feed my ATEM TVS to a PC for the encoding and hook my mac up to the ATEM HDMI input for all the rest like films, showing desktop, skype calls etc. I mean if mxlight is better and streams smoother and higher quality. I still would have 5 inputs left I believe.)

- For the people that feed the ATEM TVS in to the Intensity Pro capture card and have a soundcard with spdif in (that came in to this from the audio recording side of things like me) and use the adobe fmle for encoder.

I maby have found a solution to get sound in to the broadcast both from the ATEM and your sound card and probably in sync too. It depends on if the spdif/aes from the Intensity Pro still output audio even though it is set to HDMI.

Im not in front of that computer now so I will have to check that later and report back.

The live H264 recording does work on Macs. Mostly.
It's kind of buggy, but works more often than not last time I checked.

At the last event I live compressed to H264, It kept stopping, but then I realized one camera was on 24 FPS and the other was 29.97. And it seemed to work fine.

For the first part where it crashed - I was recording the program feed with an Atomos Ninja. I needed to get that converted to H264 fast, and so fed the output from the Ninja recorder into the TTEM TV, and let it make the H264 in real time. Worked well and saved my butt from a long render on a crummy old Mac laptop.

I wish that the H264 files would compress even smaller. I think I had it at 5 percent quality and it was still higher quality than I needed for web.

internal H264 encoder in ATEM (or H264 Pro) isnt very good, epecially in low bitrates .. Transcoding with mxlight (ffmpeg - x264) produce really good outputs ..

Hold your horses the intensity pro s/pdif will output sound and if you have the right coaxcable and souncard that can talk to it and the winds are with you you can make it work but ......

Im thinking maybe the cheapest way is to break out analog sound from the atem hdmi output and then feed it in to a souncard or a mixer. That is if youre on mac and want to use Cam Twist and just use one computer for all.

Feeding the s/pdif from the intensity pro in to my Saffire Pro 10 i/o soundcard actually does work pretty good with a good coax cable for sound. Im using consumer video cams for the testing and I forgot that the mics in those are really amped up and hot so that was the problem.

It does work though but if you want to use those cams in a noicy environment its going be really tricky to match the volume with ordinary mics from a mixer or similar. You would have to eq them really hard and probably still not be able to add a compressor without ending up the same place lol.

They are stereo too which means you would have to mute all other mic inputs or youre going to get a really strange spacy sound. I guess it still would be a pretty cheap usefull solution if you hook up external mics to them though, that should work just fine. Im thinking something like the cheaper rode video mics. That should work in a multi channel audio setup with mics and mixer combined with mics on the cams.

And doing it that way you can take long audio cables out of the equation for the cams cause audio and video would all be in the hdmi feed or if you use hdmi network extenders.

So this still could be a cheap way to getting mics in to the broadcast if you already have good soundgear and dont want to buy more stuff.

I will continue the testing tomorrow to see if I the audio is syncronized to the cams.

I found settings in my cams for the mics, to be honest I never looked before lol. The problem with camcorders an cheap ones is that no matter if you hook up external mics like the rode go they will still be hooked up to the cams internal audio circuit. The rode go uses batterypower from the cam for example which probably means the cams internal amp/system will be engaged in some way. So even though you might get better soundquality out of them its still going to be problematic to use them in a broadcast.

So back to square one cause it seems pointless to buy mics for them. I might just as well try tweak the settings and use the built in mics to avoid long extra audiocables and to be able to controll the volume seperatly for each cam.

I did a very short synch test with three cams and five mics. Two of the mics are the camcorders mics and one is a Logitech webcam. The other two mics are one TSM MT 47 and a MXL V67 and both those are phantom poweredr large membran condencer mics hooked up to my Saffire Pro 10 i/o firewire soundcard. The sound from the camcorders and webcam is not very good as they give you a very spacey sound if your to far away from them. If you are close enough to them they probably could work pretty ok if you tweak the mic settings in the cams a little.

Goran : I think , U definitely need Xkeys + Just Macros , for controlling ATEM ..

Yup . Just playing around trying to squeeze as much as I can out of it without buying more stuff lol. I have over 10 years of amateur music making/recording gear mics sound cards mixers programs and stuff I wanna make good use of for the sound part of this.

Im fiddling around so I know what I can and cannot do and there is still a few things to look in to.

Im trying to figure out how I can use Logic for all my sound both as a mixer and if I wanna record my hobby music on air. Ive done that for years before though but things got a little more complecated when I got the ATEM and try get the camcorder mics in to the "sound chain".

I did a test and realize I cannot do that when I record, I get all sorts of strange problems if I do.

I had fun though but it sounds like crap lol but round six minutes its kind of ok for a couple of seconds.
