Twitch streaming bitrate + resolution calculations

--------  Twitch streaming bitrate and resolution calculations  --------

all are divisible by 8 for best encoding results, using a list of all 16:9 resolutions

**Twitch maximum allowed on all non-partnered channels is 6000 kbps bitrate,
  for partners the maximum is 8000 kbps bitrate

BPP above 0.1 is sufficient for most broadcast. Lower may work, higher may be required.
Depends on your definition of acceptable and the amount of movement captured.


6000 bitrate **all non-partnered channels** :

1920 x 1080 60 fps 6000 kbps = .0482
1792 x 1008 60 fps 6000 kbps = .0553
1664 x 936  60 fps 6000 kbps = .0642
1600 x 900  60 fps 6000 kbps = .0694
1536 x 864  60 fps 6000 kbps = .0753
1280 x 720  60 fps 6000 kbps = .1085
1152 x 648  60 fps 6000 kbps = .1339


--------------------------------------------------

8000 bitrate **partners only** :

1920 x 1080 60 fps 8000 kbps = .0643
1792 x 1008 60 fps 8000 kbps = .0738
1664 x 936  60 fps 8000 kbps = .0856
1600 x 900  60 fps 8000 kbps = .0925
1536 x 864  60 fps 8000 kbps = .1004
1280 x 720  60 fps 8000 kbps = .1446
1152 x 648  60 fps 8000 kbps = .1786

-- Conclusion thoughts --

What this shows you is the reason why 60 fps looks better and more fluid to viewers,
your resolution doesn't matter so much. What matters is your output BPP calculation result
and the quality your viewers see. Your higher 60 fps framerate is also more pleasing to
watch from the viewers' perspective.

Let's use 1280 x 720 60 fps versus 1920 x 1080 30 fps as an example:

1280 x 720  60 fps 6000 kbps = .1085
1920 x 1080 30 fps 6000 kbps = .0964

You may think going with 1080p at 30 fps would be better quality for viewers, but actually
the math shows you otherwise, also it will look choppy and laggy to viewers at 30 fps versus
60 fps. The 720p 60 fps option even though it is at a lower resolution, gives both higher BPP
quality and a smoother, more fluid and overall better viewing experience on multiple devices.

Ultimately, it is up to you to decide what is acceptable concerning quality and
enjoyment for the viewers. Keep in mind that also many viewers are on mobile devices,
so keep scaling in mind when doing your setup based off of these calculations.
