[HELP] Bitrates (NVEncC)

[Selur]

You need to know whether you want to stick with the default values

why do they have a video bitrate > 1500 ?

Did you read the tool-tip?

variable bitrate (1pass) is a one pass encoding mode for people who just want to get an average bitrate as fast as possible, the bitrate can fluctuate a lot an the average bitrate provided is only a roughly indicator for the encoder.

it clearly states the average bitrate provided is only a roughly indicator for the encoder.

what do these 2 parameters mean

bitrate: sets a rough indicator to the encoder what average bitrate it should aim for
max bitrate: indicates a bitrate limit to the encoder, "do never use more than X kBit/s"

how should I use them

You set:
bitrate to the value you want your output to have in average
max bitrate to a value that doesn't cause any trouble during playback
If you can't figure out how to set bitrates according to what you need for your content, try using a fixed quantizer instead.

are the default figures well chosen ?

if you have to ask, then: 'No, the default values are not chosen well for your usage scenario / input / output / ..."
And no, I got no clue what values would be well chosen values.

-> If you can't figure out to get a decent quality out of NVEncC, then you shouldn't use it.
