And also pirated releases are super weird and all over the place with subtitles and video player compatibility This could streamline things

This is because blurays ship their subtitles as a bunch of text images. So pirates have 3 options: 1. Just copy them over from the Bluray. This lacks support in most client players, so you'll either need to download a player that does, or use something like Plex/Jellyfin, which will run FFMpeg to transcode and burn the picture subtitles in before sending it to the client. 2. Run OCR on the Bluray subtitles. Not perfe…

Thank you FFmpeg developers and contributors! If there's anything that needs audio/video automation, I've always turned to FFmpeg, it's such a crucial and indispensible tool and so many online video tools use it and are generally a UI wrapper around this wonderful tool. TIL - there's FFmpeg.Wasm also [0]. In Jan 2024, I had used it to extract frames of 1993 anime movie in 15 minutes video segments, upscaled it using…

I tried the exact same steps you did with the exact same movie but with Topaz AI and got very bad results which made me abondon the project. I'd be greatful if you could share the upscaled movie.

I always assumed Topaz AI would do a more sophisticated upscaling while FFMpeg only has simpler algorithms. Isn’t that the case?

Is there an easy way to denoise an audio file using ffmpeg to remove constant hum sound from an old audio recording introduced due to low quality of recording instrument?

You should take a look at sox instead. What ffmpeg is to video, sox is to audio.

What is latest sox release? Why you ignore all ffmpeg audio filters?

Has anyone made a good GUI frontend for accessing the various features of FFMPEG? Sometimes you just want to remux a video without doing any transcoding, or join several video and audio streams together (same codecs).

Handbrake fits the bill, I think! It's a great tool. Little long in the tooth these days, but gets the job done.

Handbrake can’t even reencode a video keeping the audio intact.

Every frontend offers only a small subset of ffmpeg's total features, making them usable only for specific tasks.

Unfortunately. As an example, so many people recommend Handbrake, which doesn’t even have the option to simply copy the audio stream.

LLMs and complex command line tools like FFmpeg and ImageMagick are a perfect combination and work like magic… It’s really the dream UI/UX from sience fiction movies: “take all images from this folder and crop 100px away except on top, saturate a bit and save them as uncompressed tiffs in this new folder, also assemble them in a video loop, encode for web”.

it can work but it's far from science fiction. LLMs tend to produce extremely subpar if not buggy ffmpeg code. They'll routinely do things like put the file parameter before the start time which needlessly decodes the entire video, produce wrong bitrates, re-encode audio needlessly, and so on. If you don't care enough about potential side effects to read the manual it's fine, but a dream UX it is not because I'd argu…

what... wait... In what universe do people write argument processing that doesn't process the content of all the arguments upfront AND THEN do things in the right order??

What value does tar add over plain old zip? That's what annoys me about .tar files full of .gzs or .zips (or vice versa) -- why do people nest container formats for no reason at all? I don't use tape, so I don't need a tape archive format.

zip doesn't retain file ownership or permissions.

I think the Mac version may?
