Here’s a list of the x264 settings I chose in Handbrake, and why: Therefore, I grabbed a torrent of the same TV show, and aimed to create a better quality encode at a smaller file size.īefore dumping into the x264 settings, it’s worth noting that I used a 2-pass encode, and mixed the audio down to a 160kbps Dolby Surround encode. ![]() Of course, the best way to see how well you’ve done is to find something to compare it to. File size of between 250-400mb for each 1-hour episode (about 42-44 mins). ![]() High quality, even if it takes a while to encode. In short, here’s what I’m looking to get from my encode: Recently, I grabbed the latest version (0.9.3), and decided to encode a TV series from DVD. I’ve used Handbrake in the past to encode movies and various TV series from DVD source. I pulled information on each setting from a few different websites, and while I don’t have any “final results” to show you (and the write-up wasn’t quite completed), hopefully the information’s useful in helping you to better determine what each setting does (and how it will affect encode time and quality), and to come up with your own settings. I wrote this up quite a while ago, and it’s been sitting as a draft since. It’s quite long, but you can find it here. If you do not have that time settle with compromise and you will NOT find visually that "better" yet compression for a video.Update (June 25 2012) – I have a more complete & updated version of this write-up now. So fix the broken parts, not designing it over and over again. But we know that x264 "machine" is one of the best things out there. Unless the whole design is fundamentally wrong. Different part of an object needs to be reinforced or changed. They find a problem and try to localize it and fix it. When an engineers builds a complex machine, they do not design it from the scratch and let it "print" again. Or devide movie into clips/parts (this particular thing is where I do not understand why it did not pick up yet in general, technology is here) Or encode it separatelly and use stichable. Then Encode video again using zones, where you increase bitrate (lower quantizer or multiply bitrate). Then watch the video again, and make a timetable on a piece of paper what scenes need to be fixed and mark also degree of a problem. You encode to just highest possible quantizer for most scenes. Yes, if you want to push boundaries and pressing compression efficiency even further and not to see quality drop much, it has to be done in fazes. Any advice on how to increase encoding speed without any impact to quality or increase quality further while keeping or reducing file size would be greatly appreciated. Are they too aggressive or would they even have a noticeable impact on the final quality or file size? Should I use separate settings for film and animation or would these work equally well for both?ĭue to these settings the encoding speed is fairly slow, but I suppose that's the price for quality. My biggest concern is some of the settings that were added manually such as mixed-refs, vbv-bufsize, vbv-maxrate, and rc-lookahead. Any reason I should be going back to 16? Any settings I could change to further increase quality or reduce file size without encoding time getting really out of hand? Originally I was going to go with a Constant Quality Rate Factor of 16, but after doing some tests I decided to settle on 18 because I couldn't see a difference in quality. My settings are already very aggressive and I'm looking for some advice on whether I went too far in some cases or perhaps not far enough. I use Android based TV boxes to play back content and backward compatibility with older or low spec devices is not important. Encoding speed is not important to me, but would like it to be reasonable. I want the results to look the same as the source without any noticeable difference in quality while still reducing size as much as possible. I mostly have movies, TV shows and animations. I've spent a good amount of time trying to figure out the best settings for encoding my video collection. ![]()
