![]() ![]() 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). ![]()
