cool thank you very much for your help
No problem mate.
If she will be streaming to twitch i believe they have a quality test based on your bandwidth. So you put in your upload speed to this calculator and it will tell you what quality you will be able to stream with stability.
What program will she use to stream? I would recommend OBS (OpenBroadcasterSoftware) I have used it to stream to console and pc, plus it is totally free. It is used by many high profile streamers, on console and pc.
Great piece of software, plus a great community to help you if needed.
Just also be aware that viewers do not get the option to change the quality of your stream until you are twitch partnered. I believe you wont get that until:
'To qualify as a Twitch Partner, we look for:
Average concurrent viewership of 500+ (not just a one-time peak)
Regular broadcast schedule of at least 3 times a week'
So when someone is not partnered if they stream in 1080p it means their viewers can only watch in 1080p which is fantastic but a lot of peoples internet won't allow them to watch that higher quality therefore they wont be able to watch your stream. So i would say streaming at 720p is a must until she gets partnered.
Why stream in 1080p if only 25% of your followers can actually watch it.
Any other questions fire away!
