ffmpeg is a very hard workhorse that few recognise and the giants abuse by call it theirs. Literarally its coding is everywhere on media players with many times included without even open source acknowledgement. Most of the video editing software around is just recompiled wrappers of this gem. P.S. I did my university project in mpeg long time ago (compression and decompression of bytestream using fft2 and performance analytics).
Video editing aside, I can plug a video in it with zero arguments and it some how comes out with a ~80% smaller file size and no noticeable quality loss. That alone is such a game changer, I've got a right click script for it and everything
@@simulping4371 FFmpeg does a lot of optimizations like removing duplicate frames for example. You can also tell it to use more advanced feature sets of video encoders, giving you even better quality at the same bitrate.
as someone who works with the C api, ffmpeg is the tool I have the strongest love-hate relationship with. The api can be an absolute struggle at times, but it's incredible that we have such a powerful open source tool at our disposal.
I’ve never felt the need to use the C API. One project I did involved extracting telemetry data (accelerometer, gyroscope, GPS) from videos captured from GoPro cameras. I wrote a Python script which called ffprobe to identify the right streams and the exact locations of the data packets and their timestamps, then I could read those parts of the video file directly and decode the packets using the standard “struct” library.
FFmpeg is so useful in the VFX/CG industry, it's used for converting textures, encoding reviewables from several different outputs, adapting output with stuff like slates and overlay data for client review, subtitles, using FFprobe for capture certain EXR metadata, the list could really go on for paragraphs. It really tells you something when FFmpeg is far more flexible and useful than Autodesk's RVIO, which costs thousands for licenses and doesn't even have 5% of the functionality of FFmpeg.
Yes, but Autodesk has by far the bigger advertising budget. Telling people how wonderful you are tends to count for more than actually putting out a superior product.
It's because of how (relatively) pretty and easy-to-use RVIO is, compared to ffmpeg. Don't get me wrong, it's one of the first things I install on my fresh Linux installs, but the CLI interface is not for the faint of heart.

I use this since I got into Linux in 2008 and I even teach all my friends how to use it. Since all of these Converter Tools are nothing else then FFmpeg with adware.
I remember searching for a decent converter back in the early 2000s, I swear Advertisers were working really hard to push ffmpeg aside for their shit quality software. I didn't find ffmpeg until much later.
It's such a complex program that it would take 100 hours to fully explain how to use it, yet 100 seconds can give you enough of the basics to allow most people to use it as they need it on a daily basis. The only thing I would've added is that the order of arguments matter.
True! For example, if you use *_-ss_* and *_-to_* near the beginning of the command, then you're cutting a clip out of the original media file, any further arguments that have a time component to them are applied within the context of that clip. For example, trimming a song down to a ringtone: *_FFMPEG -ss _**_01:00_**_ -to _**_1:45_**_ -i infile.mp3 -af "afade=t=in:ss=0:d=1.5, afade=t=out:st=40:d=5" -c:a libmp3lame -b:a 192k outfile.mp3_* . The fades' start times of 0s and 40s don't occur at 00:00 and 00:40 of the original song, they happen at 00:00 and 00:40 of the clip - therefore 01:00 and 01:40 in the context of the original song.
Internet is flooded with over complicated, bloated, borderline useless and paywalled format conversion tools. ffmpeg is so simple yet so powerful, once you realised how to use the command line then the possibilities are endless.
ffmpeg is really good. I use it to create partially transparent videos (rgb + alpha channel). Those can be imported in basically any video editor. They work in OBS too. I'm using the codec "qtrle" and output format "mov".
FFmpeg is a bit to video what ImageMagick is to images. There is also another audio/video library called GStreamer which I think is a bit like FFmpeg but I guess more oriented towards playback than encoding.
Ffmpeg is one of the most powerful programs i know! I've never seen a program learning Curve similar to it! From the simplest cutting or converting of Videos to gpu based live Resolution encoding for rtmp! Such a powerful tool!!
I'm starting to believe that you are an alien or some sort of AI who found out a way to get out of the computer. I tried hard to learn FFMPEG but I was always confused by what the hell is going on with commands... you explained like its NOTHING! bruh... even toddlers can use your videos and become a developer. any way thank you very much ♥ keep up the great content as always. we really need you! =)
He just read the API description and exemple, there is nothing special about it you know. What he just showed are really the most basic command of ffmpeg
I just got started with ffmpeg libraries 1 week ago to export image sequences instead of multiple images as a single video file And now you make a video about it xD
I've been working on my own project to code a FFMPEG library for personal use. The idea is to essentially create an audio DSP that will take in audio formats / streams and process them to an output. Goal is to make an exec that can run on a raspberry pi and use it like a digital pedal board. Just working on the physical parts now :D
When you also have youtube-dl and put the ffmpeg executable in the same directory, you have the ultimate tool for downloading videos from the internet. That’s because youtube-dl has certain actions written into it, that will be automatically done by ffmpeg like merging the audio and video file of a downloaded RUclips video together (since with high-resolution downloads audio and video are two separate files).
FFMPeg is the goat. our entire company's video infrastructure is relaying on it and it works amazing. There are so many options is really crazy to think about the work that went into this tool.
I'm very pleased that you included the bit about ass files. Lol. At a previous dev job, I worked a lot with video and ffmpeg, and one of the things I worked on was ways to burn-in subtitles into videos, and the fact that everything had to be converted into ass files really tickled me. I still can't believe that "Advanced Substation Alpha" somehow ended up being "ass"
when i wanted to write subtitles i had to pick a format. knowing nothing, i picked .ass because it had some features i wanted and the file extension. later learned it's like the industry standard or something
@@sodiboo it is industry standard but at the same time it's also the least supported subtitle format on TV hardware . . . try finding a TV that can natively play .ass subtitles without relying on another machine to transcode it.
I found out about ffmpeg 5 years ago when i had to split a movie in two so i can upload it on disks for my grandfather to watch on his entertainment system, i've been in love with it since.
@@xXZian6Xx Because it's more like half a streaming server half file server. It has a few editors in the web UI for opening different kids of files, though mainly for media.
I use this to compress my videos on discord, It saves me a lot of time and trips to visiting websites that might track you. I also started using VLC ever since Microsoft changed their groovy app to the media player (they might have added more telemetry). Best decisions I've ever made!
Ffmpeg is surprisingly well documented too. Made a dirty script in the past that automatically color graded clips based on the folder they were placed in.
just saying changing it to .mov is not changing the codec it is just changing the container containers like mkv,mp4,mov,avi are very different from codecs like vp8,vp9,h264,h265,av1 etc
I've once used FFmpeg to compress a 1.3mb video into 5 kb, the quality of course died but you could still tell what was happening. Now why did I do that you may ask? Good question, unfortunately I don't have an answer
Small nitpick at the command shown at 1:46. If you try to run that command you probably won't get the result you're expecting. The video will probably not start at the timestamp you specified and it might last under 10 seconds or slightly above 10 seconds. This happens because of how video codecs work, usually you have a keyframe that contains a full image and the following frames until the next keyframe only contain the parts of the image that change. That's why if you copy the video, ffmpeg has to use those keyframes to make sure you don't get a video file that doesn't play properly. If you want to solve this you have to actually re-encode the video and ffmpeg will make sure to output exactly what you asked .
ffmpeg has saved me literally hours of waiting on my computer to reencode things, it's brilliant for splitting out video and audio, editing the audio, and recombining after the fact. No need for premiere or vegas or resolve (my favorite at the moment, just very bulky when you just need to edit the audio!), just -c:a copy or whatever the flags are and you're off to the races
knowing how to replace audio or cut stuff out of a video without having to reencode it by using ffmpeg with the argument "-c:v copy" has saved me probably hundreds of hours
I did use ffmpeg to automatically remove duplicated frames, merge all videos and audio and create a timelapse-lofi screen recorded video in 1 night using my phone. All of those happening with right label for video and audio file then python automate things with ffmpeg.
ps the *-ss* option is the *start position* option and basically is where you seek to the location to start the media file manipulation. Hope you have a great day & Safe Travels!
I tried to make a video from single frames from my gopro in my editing software. Absolute disaster. With ffmpeg, it took hours to learn how to do it, but minutes to make the file. Brilliant bit of software.
