![]() ![]() By default, Handbrake's "High Profile" preset uses h264's High Profile, Level 4.1, while Handbrake's "Normal" preset uses h264's Main Profile, Level 4.0. Yes you can choose the h264 profile under the video tab. I kind of wish they'd use a different name rather than "High Profile" so as not to cause confusion with the h264 High Profile, but anyway. I was referring to Handbrake's own presets. It's in the H.264 profile drop down on the video tab. How much difference it makes to quality I'm not sure as I've pretty much only ever used High Profile.Īre you using an old version of Handbrake? Aside from the presets for different devices, I have Normal and High Profile. The setting x264 uses for partitions changes a little according to whether Main or High Profile is used. I'd use the latter unless I knew I had a reason not to. The "Normal" Handbrake preset defaults to Main Profile, Level 4.0, whereas the High Profile Preset defaults to High Profile, Level 4.1. Whether you use the "Normal" or "High Profile" Handbrake speed preset, if the x264 speed preset, Profile and Level are the same, then the same encoder settings will be used. I just checked to refresh my memory and I thought the Normal preset didn't use the default x264 settings, but it does. Maybe the "veryfast" speed preset anomaly jagabo referred to earlier accounts for some of the reduction in file size.Īnyway, I was a bit wrong regarding the Handbrake presets. Nothing called "Main".Īssuming we're talking about Handbrake's "Normal" vs High Profile presets, "Normal" uses a faster x264 speed preset by default (very fast) which probably accounts for much of the difference in encoding speed. So you say to Always use High Profile, why is this? I normally use Main and notice no problems, whenever i use High the same 40 minute episode is around 700-750mb compared to mains 550ish and taking quite a bit longer? Are you using an old version of Handbrake? Aside from the presets for different devices, I have Normal and High Profile. Many times I've seen something "odd" in an encode, but after looking carefully at the source video I've realised it contained the same "oddness". The quality of DVD/Blu-ray video varies quite a lot, even from episode to episode on the same disc, and chances are the encoder is just re-encoding a lower quality source. Most of the time it's probably not the encoder's fault. PS If you think the encoding quality for a particular video (or section of it) isn't the same as the rest, before blaming the encoder make sure to check the source video. no need to encode the whole lot every time. Don't forget handbrake lets you select the start and end points for encoding so you can just encode small sections of the video for making comparisons. There can be other factors involved such as any filtering being used (ie de-interlacing etc) but I'd try a slower speed preset first to see how that goes. it's not a perfect system but as a general rule it works very well. In an ideal world a given CRF value should give you the same quality relative to the original video every time, but sometimes there's small sections of video which are particularly hard to encode. I generally use medium or slow (sometimes slower if I'm not in a hurry), so I can't comment much on the effect of using faster presets. The fastest speed preset I've used myself is medium. The x264 speed presets don't effect quality too much (for a given CRF value) but in theory they can, and at the faster end of the scale it might become a little noticeable. You can still select the Main profile under the video tab if you like. Make sure you start with HandBrake's High Profile preset as the rest use non-default x264 settings (even when changing the x264 speed preset).
