When setting number of ref frames to more than 6 in x265 it says "cannot set up codec. Bitrate to low" when trying so save.
http://x265.readthedocs.io/en/default/cli.html#cmdoption--ref (http://x265.readthedocs.io/en/default/cli.html#cmdoption--ref) should shed light on the reasons.
Thanks for the info. So from what I gathered it is limited by the commercial version of HVEC/x265. That kind of sucks that the new standard (HVEC) is limiting it more than X264. I wonder why they would do that.
More to help you to have a stream that can be decoded by most devices/codec
Maybe you could set 6 as the max for X265 settings. I assume that would just be changing one variable in the code. It would avoid people running into that and wondering what is wrong. It took me a while to isolate ref frame setting higher than 6 as the culprit out of all of the X265 settings.

This should be fixed now: https://github.com/mean00/avidemux2/commit/c3fa6a3d42bf434189daaaa2a43b8ee637ea321d (https://github.com/mean00/avidemux2/commit/c3fa6a3d42bf434189daaaa2a43b8ee637ea321d)
