Hi! I let you check our tutorial here which explains how to understand the vainfo.

With what you gave us, your GPU does not support the H265/HEVC protocole. The low bandwitch option is actually using the H265 against the H264 which give better results (understand less artefacts) for the low bitrates. Since your GPU does not support it, you can't use it.

Feel free to open this issue again if you have any question. Cheers!
