Student association OUBS (YouTube) has been using vMix now over 6 months and it's awesome! On this weekend we are doing live streams from the biggest hackathon in Finland (1300 participants).

Livestreams and VODs can be found here http://live.hackjunction.com/

Everything was produced in 1080p 50p format (except 1 cam and smaller stage in 50i). Original idea was to use NDI between all computers but we ended up using 3G-SDI from Main computer to recorder (through VA 4k) but NDI was also working fine. Image from smaller stage came with NDI in 1080 50p format using computer that can hardly stream 720p 25p.

On main stage, we used tally lights on both warm cameras using wifi + smartphones. Animated TG background was built in AE but text was coming from vMix using multiview and triggers (why titles can't support videos/image sequences?)

Example of animated TG and merged/anmiated PIP shortly after ?t=1h38m14s
