AV1 is very fast and versatile but…
Calculate vmaf before you encode the whole file. -> https://github.com/alexheretic/ab-av1 has a search mode with samples, the estimation of time and filesize is very good and does everything in one step

RFC: redb (embedded key-value store) nearing version 1.0
My case is ab-av1, a cli for encoding videos. The local db stores cached vmaf analysis.
- I'm just running videos through libsvtav1 on ffmpeg with -crf 35. Any tips to improve this command?
-
A little script to parse large libraries to AV1, if you're interested
If the goal is space saving and a consistent visual quality rather than just having a library as AV1 for its own sake, I'd use ab-av1. Not sure how (or if) it'll handle the Opus audio channels cases, but bugs can be filed.

Feels like re-encoding video gets harder and harder to improve (and use!) when new ones come along.

Looking for some good AV1 testing and comparison results.
Use this tool and you will get excellent results https://github.com/alexheretic/ab-av1 calculates and converts automatically calculates the vmaf and crf properly

Show HN: CompressX, my FFmpeg wrapper for macOS, made $9k in the last 4 months
For lossless cut, there's the LosslessCut [1] app, which even has an experimental but mostly working version of a "smart cut" feature [2] (aka. only re-encode the minimal mandatory amount of frames if you trim at a point between 2 key frames)

Cleaning up my 200GB iCloud with some JavaScript
> thought I cropped/edited a video, it is still there in full length and resolution
It's been possible to create a clip from a video file that merely changes what parts of the video are displayed without effecting the data in the original since the Classic Mac OS days.
If you want to completely remove unwanted portions of a video to reduce the size without a loss of quality, there are many options. LosslessCut is one option that is both free and open source.

Lossless Cut is my new favourite tool to cut parts from a video without any hassle
Lossless Cut is probably the simplest way to cut out parts of a video without having to re-encode it or use an online service. It is open source, free and available for all platforms. It is in essence a frontend for FFMPEG and cuts without re-encoding, so the results are instantaneous.

Tips and utilities to manage collections of videos.
Additionally I would like if possible to shorten (both to reduce dimension and to make them less boring) my videos by trimming the beginning and/or ends where often there is nothing interesting happening and possibly change the thumbnails for easier identification. Do you know of any tool that does the job with the minimum quality degradation possible? Many years ago I've tried with some videos and a tool I don't remember anymore, ending up with a bunch of corrupted files :( I've found https://github.com/mifi/lossless-cut for the point above.. need to try it. please let me know what experience you have with it.

Why is Clipchamp Ruining My Videos?
Lossless Cut would probably be a better choice for this. Will let you cut out the commercials without having to re-encode the video.

VidCutter: A program for lossless video cutting
>Of course, you could only re-encode only the GoPs that get broken while keeping the rest intact, and I guess this would be better and a lot faster than re-encoding everything. I don't know if any application tries to do this.
LosslessCut does have experimental support for this partial re-encode called "smart cut" [1]. Since it's using ffmpeg internally, the challenge become how to instruct ffmpeg to do this[2]?
