I'm basically trying to encode every frame as intra frame (only spatial encoding) with no When in doubt, stick to the recommended range or use the default setting for the Preset you selected. 265 (High Efficiency Video Compression - HEVC) is one of the replacements for H. When you use slower presets, x265 tests more encoding options, using more computations to achieve the best quality at your selected bit rate (or in the case of --crf rate control, the lowest bit rate at the Preset and tune have special implications. Presets are usually adressed by their corresponding names like fast, medium, slow etc. x265 has ten predefined --preset options that optimize the trade-off between encoding speed (encoded frames per second) and compression efficiency (quality per bit in the bitstream).
