New in the encoding world , where to start?
Hello, long time ago I was immersed in video compression, I used software like MeGui, eac3to, mkvmerge, etc... But I've been disconnected for many years, and I would like to start compressing videos again, but I don't know where to start.
I have 20GB, 30GB, or larger files, and I would like to compress them with minimal loss of quality. In the past, I remember extracting the audio from the videos and compressing them separately with eac3to but I don't know if there are new methodologies? better ways to encode video. Is MeGui still used? What should I use to compress with the H.265 codec? What software should I download? . For example, in a post I've seen the following: "My current settings are; 10-bit. CRF 17. Slow preset. selective-sao=2:no-strong-intra-smoothing:rskip=2:rskip-edge-threshold=3:aq-mode=3:aq-strength=1.2:deblock=-3:-3" Where am I supposed to write those settings? What software is being used there?. I hope you can help me and help me encode videos from scratch. Thanks in advance for your responses. |

Is there a particular kind of content you're working with? Optimum tunings can be different for cel animation versus grain movies versus a "first do no harm" setting that might not offer maximum compression efficiency but will do a good job with most content. HDR settings can be quite different than for SDR as well. |

Which one is better, all-in-one UI or CLI ? . In the past I used UI , but I always had the impression that CLI utilities were better, but I never tried. If CLI utilities are better, I would like to try with them, but where should I start? . I'm a complete noob and I would like to compress some big files (basically movies) with the codec h265. Thanks for your response. p.s.: Is Avisynth just valid to use with .avi files or you can use other codecs , like H265? Is .avi files still use for people???

Well, those lines were just an example. To be honest, I have no idea what they mean. In what software do you write those lines? In cmd? I need space on my hard disk, and I would like to compress some large files (30 GB, 40 GB or more), basically all kinds of movies (animation, classics, black and white, etc.). What would you recommend for me to start? Thanks in advance for your help and advices. Last edited by MeoLessi9; 8th February 2024 at 07:48. |

They are remarkably well documented for an open source video tool: https://x265.readthedocs.io/en/master/cli.html Quote:
Optimally reencoding a wide variety of content involves some trial and error to determine your own tolerance for quality loss, and different parameters for different kinds of content. I just bought myself a rugged 5 TB portable HD for $150. You can potentially spend more than that just in your electricity bill reencoding enough to save 5 TB. If you're in this to enjoy the intellectual challenge and don't mind a couple of months of learning encoder tuning, okay. Otherwise there are much more pragmatic ways to have more storage. |

Dude! Why make it complicated? Just use Ripbot264, Staxrip or Hybrid for encoding. Underneath they all use x264/x265 so the end result will be the same. It will take a lot of time if you first have to learn the CLI and most/all x264/5 options before encoding

x265 isn't like FFmpeg, it's a codec, FFmpeg is a powerful multimedia framework that provides users with the ability to process and manipulate audio and video files. It's pretty much the work horse behind most encoding apps. Like microchip8 said, start with something like RipBot264, Handbrake, Staxrip, even Fastflix, etc.....Hybrid is VERY complex. Not wanting to sound biased, but my fave app is RipBot, I have been using it for years, and there's even a "special" build (that I had something to do with), which offers users a LOT more encoding & filtering options (see my sig for links to 3 variants) But which ever app you choose, you will have a learning curve before you get any of them to do exactly want you want, or need.

Lots of use use x265 directly (often piping from ffmpeg) so we can pick the build we're working with, and easily isolate between what the encoder is doing versus the preprocessing upstream of the encoder itself. That's not the way that most people use it, or should. But it is how a lot of the people here who give advice do. |
