Let me quickly run through our setup here first... we have a Blackmagic Design ATEM Television studio (not the new model) it supports 1080i50 max (no 1080P sadly). We use this to vision mix our cameras, this then feeds into Caspar via a Blackmagic Design Videohub (this does support 1080p) and then into a Blackmagic Design decklink which we turn off or on in Caspar.
My question really is this (and I think I know the answer but I would like some of your input to check on that):
When running Caspar CG Server currently we peak at around 15% CPU, with this in mind I was tempted to take the 1080i50 Decklink (HD-SDI) input and have Caspar CG Server output in 1080p60. But will Caspar CG Server cope with this OK or will there be issues converting that 1080i50 input on the fly without eating up all the CPU?
I have the option to convert this in our Streaming Server software (Open Broadcast Software) but I think it's best to do this convert as soon as possible, so that we can see the fully mixed/converted output on our internal TVs for QCing, would everyone agree?
This is a live stream we made the other day: https://www.youtube.com/watch?v=qxZsGzg-ow8&t=402s
, it has quite a lot of interlacing type movement so this is why I'm trying to get the stream to YouTube to be progressive not interlaced. Any off-topic recommendations you may have about how we can do that YouTube video any better please PM me I'd be very glad to hear them (we're doing another one next week).
