ABR and x264 HQ-Insane, HQ-Slowest, HQ-Slower vs. LAME --alt-preset insane, extreme

If you want an analogy, lame's most similar options are -q / -f / -h.

Hi akupenguin, My only acquaintance with lame is using it with the presets, so I am not very clear on what the other options mean. When you use the switch -q/-f/-h do you also have to supply a bitrate? (You don't with the presets)

There is no analogy using only lame presets. The idea of x264 profiles is that they increase the coding efficiency. This means you either get a higher quality stream in the same amount of space, or the same quality stream in a lower amount of space (or some combination of both).
