I Live streamed to Youtube with ATEM Television Studio

Edit: I forgot to mute the sound when I was monitoring my cast on youtube. That´s why it acts funny cause it loops back in to the broadcast so you have to mute the sound on your monitoring browser if you only use one computer for everything.

I did two casts/live stream tests to Youtube using my ATEM TVs and my Intensity Pro capture card, 1080p 6000 Kbps and 720p 4000 Kbps . In the 1080p I only used the ATEM and FMLE, in the 720p I used Camtwist too. I´m on Mac.

What I think is strange is that the live camera feed from the 1080p cast looked better compared to the 720 p but the 1080p archived version looked worse than the live feed. Might be a temporary problem though cause this is the internet and that´s the real bottle neck not your gear.

I never bothered to compare the 720p cast the same way which was really stupid of me so here I just have a hunch but I think it was the same. Not 100% sure about that though.

What I am sure of though is that the film clips I broadcasted was taken with an old Iphone4. Even though they probably are compressed and converted a few times (I forgot I just grabbed them on the fly) they look so much better compared to the live cam feed.

The same cams look very good hooked up to a TV and through the multiview1 output on the ATEM.

(And no I do not think I would get better quality screen capping the feed even if it´s over USB3 with that program people recommend people to download.)


My cameras are two ordinary consumer cams, one Sony cam and one Panasonic cam.

So is this a camera problem or an ATEM problem or an Internet limitation we still have to live with?

I´m talking reasonable quality in fullscreen watched on a 37 inch and up TV not computer screen size "watch boxes".

Scroll through these two clips if you want to check it out. They suck I do know that but they are only tests.

The setup with Cam Twist in the equation is really interesting because Cam Twist will see your Intensity Pro as a webcam which means you can use it for both your HDMI cams you have hooked up to the ATEM and as many webcams as your cpu can handle without maxing out. Cam Twist can also besides switch back and forth between webcams and other cool stuff also play back all your video clips so there´s no need for extra media hardware.

4000 kbit/s H.264 produces visible artifacts, it is again compressed on YouTube. That's just how compression work.

Yes I guess thats the problem. I did a few 1080 in 6000 too but it was no big improvement just a little. On my Ipad it works brilliant though.

Could you point me to a clip with mxlight over usb3? It would be interesting to see if its the same. I have good PCs too so I can swap if mxlight works better.

Well, the ATEM TV Studio has a hardware h.264 compressor built in. That sends a compressed signal over USB2. MXLIGHT works by hijacking this feed, package it and stream it.

USB3 is for the 1M/E and 2M/E that does uncompressed video as a "capture card". They dropped this feature on the newer models though.

I tried usb and screencapping from media express in to the cast but it sucks its useless for broadcasting. Maby for capturing to disk it will work ok I doubt it though. Thats why I have a hard time believing that anything over usb would work in a live broadcasting situation. Maby usb3 but I doubt it. So thats why I want to get a chance to watch a cast someone did with mxlight.

I read somewhere somebody took the feed out of the sdi instead of the hdmi cause the h.264 can be done by the computer only then. He used a minirecorder and thunderbolt into his mac instead of like I do with the intensity pro over hdmi input.

Im going to get at least one of the minis anyway looks like good usefull stuff for sure. I just hope they arrive in working condition though cause with my bmpcc I tell you its a joke they send me a replacement cam with a dead battery. The first one wouldnt record and next one dead battery hmm wonder if uou can trust the gear they sell at all I read people have lots of problems with their gear.

I have taken an hdsdi output from the atem1 into my decklink 4k. I then used wirecast for youtube to stream. I have had some success doing this. I have limited upload speeds and have tried using the sd sdi out and streamed at lower resolutions. That worked fine as well.

Sounds good it works with this setup too. Do you have a link so I can watch the broadcast?

Im playing around/investigating to see how good quality you can get in a livestreamed broadcast over the internet, been doing that for a couple of years now. Once I think Ive reached a high enough quality at least the same level as what I have on my local TV stations in fullscreen on my flatscreen TV I will start make some real broadcasts. Well my kind of real broadcasts lol, Im just an amateur so its gonna be amateur stuff.

Anyway it would be really nice if people would post links when they broadcast and tell what they used for it so we can figure out the most flexible, portable and cost effective way with the highest possible quality to broadcast.

When youtube decided that anybody with a good standing channel can live stream things started to get really interesting since they let you broadcast with much higher speed than the other sites that allow live streaming.

I also found out you can forward the live stream to places like Google,+ Facebook and even forums that allow it since youtube simultaniously will provide a stream that works for different kinds of "environment" and hardware. I even could watch my stream in good quality on my brothers really cheap singelcore samsung phone.
