NotEnoughAV1Encodes-Qt VS lossless-cut

I like using NotEnoughAV1Encodes. There's also Av1an, and ab-av1.

I wish AV1 had more compatibility. Just playing around with NotEnoughAV1Encodes took a dumb 10-second clip with almost no movement from 24MB from my DSLR to 1.1MB after the AV1 encode. It's a bad example for a video, but I was just randomly trying AV1 with things and was impressed with the ratio.

If I'm not in a hurry for something to process then I set it to run on that. For instance, when I was looking at the AV1 codec I had it grinding NotEnoughAV1Encodes for days at a time.

If you want to mess with AV1, then there's AV1an that has a feature to target a VMAF. ab-av1 has their 'crf-search.' Although, most of the time I just use NotEnoughAV1Encodes with settings I like. Although, granted AV1 has less compatibility and it takes forever.

For some things, I've been going even slower using AV1 with NotEnoughAV1Encodes. Although, there's less compatibility for AV1, so keep that in mind.

NotEnoughAV1Encodes is great for AV1, I'm not savvy enough to get AV1 to grind all my CPU cores without it.

Do you do any videos? I've been playing with the AV1 codec using 'NotEnoughAV1Encodes'

Do you mess around with video at all? I just found out about the AV1 codec. Been using NotEnoughAV1Encodes to use all my computer cores to compress video. Then comparing the quality difference with ffmpeg-quality-metrics using VMAF. 33-second test video with my phone went down from 23MB to 1.6MB with nearly no quality difference. It takes forever to encode though. May not be compatible with all devices/browsers/etc. Then there's ab-av1 to help find the best settings.

this program is pretty boss, https://github.com/Alkl58/NotEnoughAV1Encodes-Qt

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]?
