-1 means automatic (on in constant QP mode, off otherwise).Note that this options modifies other parameters (gop-ref-dist, num-ref-frame, gop-pic-size).It may be incompatible with some playback devices (such as the first generation AppleTV).Enables or disables “Pyramidal B-frames” which can improve compression efficiency.Note: you can also use cabac (same as cavlc with reversed meaning).It may improve encoding performance slightly, especially on older hardware.Use CAVLC instead of CABAC entropy coding.-1 means automatic (32 in constant QP mode, 1 second long otherwise).Number of pictures within the current GOP (aka “keyframe interval”).Note: may be sanitized to a lower value in some cases to avoid hangs.-1 means automatic (4 in constant QP mode, 3 otherwise).Distance between I or P reference frames, from 1 to 16.0 means unspecified (set at runtime by the implementation).Number of reference frames, from 1 to 16.Sets the trade-off between quality and speed, from 1 (best quality) to 7 (fastest speed).See the option’s comments for acceptable values. The following value types are supported (each option only accepts one value type):Ī number that can be written without a fractional or decimal component.Īn alphanumeric string of characters. If using HandBrake’s command line interface, use the -encopts parameter as follows: -encopts="option1=value1:option2=value2" If using HandBrake’s graphical interface, you can set the options in the Advanced Options field on the Video tab in the following format: option1=value1:option2=value2 Generally speaking, it is not recommended to change these parameters, as the built-in presets offer a good range of options for common uses. The QSV hardware encoder has a limited set of advanced encoder options. To minimize this effect, disable any filters that you do not require. It is also common, particularly on lower-end or older hardware, for the CPU to be a bottleneck which will cause lower than expected performance. As such, it is normal to see high (or even 100%) CPU utilisation even when using QSV. These operations all happen in parallel as the job progresses. Video decoding (if QSV decode is disabled or your source is in a format which is not supported by the QSV hardware).HandBrake supports both QSV encode and decode. These are a good starting point for configuring HandBrake to use these encoders. The following presets are available under the ‘Hardware’ category in the presets menu: If your system is not supported, the option will be disabled. Support for the Intel Quick Sync Video encoder is enabled in preferences on the video tab.
