lossless-cut VS AutoEq

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)

> 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.

LosslessCut

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.

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.

Lossless Cut would probably be a better choice for this. Will let you cut out the commercials without having to re-encode the video.

>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]?

I'm trying to follow this general process of EQing laptop speakers, which cites the AutoEQ Github wiki for digitizing a frequency response graph and converting it to CSV. The OP references converting the graphical data from an A-weighted scale to the dB scale, as well as interpolating more data points on their 20-frequency graph. Even without worrying about interpolation, I tried to follow the Github guide and just got hopelessly lost.

I have a topping dx3 pro+ and use https://github.com/jaakkopasanen/AutoEq/tree/master to play around with EQ's

jamesdsp/ An audio effect processor for PipeWire clients. It also uses presets from AutoEq.

what u can do do is go here https://github.com/jaakkopasanen/AutoEq/tree/master/results, pick and download the file for ur headphone and add it in APO equalizer as a second "graphic equalizer with variable bands" that will correct the first EQ with a curve made for ur headphone

Parametric EQ apps for Android can be googled, I use PowerAmp. The Qudelix takes care of all of that with its app to the point where you can load from a giant list of EQ sets they made from community data - Not all of it is accurate, better to go to the source. You can find EQ presets on the oratory1990 subreddit, Amir’s reviews for that particular headphone on Audiosciencereview and crinacle’s as well as rtings here: https://github.com/jaakkopasanen/AutoEq/blob/master/results/INDEX.md

I always recommended hearing before buying, but I'm assuming you can't try many in person so use AutoEQ to get an idea what you like - https://github.com/jaakkopasanen/AutoEq

https://rogueamoeba.com/soundsource/ (this has parametric EQ but it's a bit buried IIRC. It also has built-in support for AutoEQ according to this page so you might have to do almost nothing if you like the Harman curve)
