[QUESTION] About HLG Transfer and Bandicam about x264vfw HOT 4 CLOSED

Hi.

1. --transfer arib-std-b67 and --alternative-transfer <string> will be supported in the next version with updated version of libx264.
2. Do you mean real crash and not "Failed to initialize codec" message? May be you didn't disabled log in x264vfw configure? Bandicam don't like x264vfw's log window so better set Log level to None. Also for Bandicam I would recommend to set Zero Latency option to not lose few first frames (if you not going to use Output mode: File). Otherwise I don't have any problems with encoding in RGB with Keep/Accept only RGB or with Keep input colorspace+Prefer RGB colorspace.

Also if you going to encode in RGB better don't mess with options (range/colorprim/colormatrix/transfer) because that are incorrect values for RGB output (otherwise RGB input will be encoded as if it was YUV input i.e. with incorrect colors) and instead of --qp 0 simply set rate control to Single pass - lossless

1. No ETA for new version;
2. I doubt Bandicam can capture in HDR (RGB or not) and afaik there no such thing as HDR RGB. Also HDR need at least 10-bit input (capture). This options do tell H.264 decoder which colorspace the encode is but x264vfw/libx264 do NOT convert input to such colorspace and only treat input as if it already converted. So when you say --colormatrix "bt2020nc" instead of default for RBG --colormatrix "GBR" your RGB signal is treated as if it was YUV BT.2020 signal (i.e. G->Y, B->U, R->V).
