*Expand for Important Notes* *1. On Download Availability* Zeranoe, which was featured in this video, has discontinued providing FFMPEG binaries since 2020. You can download from this github page instead, as linked to by the official FFMPEG downloads page: github.com/BtbN/FFmpeg-Builds/releases. Windows users can go for the "ffmpeg-master-latest-win64-gpl" build, as the GPL version is likely to have the most features. *2. On Debugging and Help* Unfortunately due to high IRL workloads, I'm not able to look at your commands and help diagnose problems. You may contact me at hello(at)nerdfirst(dot)net for paid consultation, if you really see the need. *3. PSA* If you have a question, please post it as a new comment, *_not_* as a reply to one of my earlier comments here. KZread does not reliably notify me of the latter, which means I may miss your message!

Amazing walkthrough. when starting out you search up how to use these command line tools up on forums or reddit and you basically get told to not be dumb or they act all high and mighty and start explaining as to why what you want is wrong. in short they give you everything but a solid answer or what you want

@NERDfirst

8 жыл бұрын

+Jessie Wilson Hello again! Hmm, interesting, sounds like you want to do quite a few things, so I'll actually start with something simple and "evolve" it to suit your use case. So we start off with this, which says that we want to copy the video but reencode the audio. ffmpeg -i inputName -vcodec copy -acodec aac outputName I'm not sure what you mean by (96), is that the bitrate? If it is, then you might want to do this: ffmpeg -i inputName -vcodec copy -acodec aac *-b:a 96k* outputName Finally, to mix 5.1 channels down to 2 - Interestingly, there are several ways to do it. This is the simplest "default" way, which is handled by FFMPEG natively: ffmpeg -i inputName -vcodec copy -acodec aac -b:a 96k *-ac 2* outputName These are very advanced, but apparently people aren't too satisfied with the quality of FFMPEG's built-in downmixing, and have proposed their own methods: forum.doom9.org/archive/index.php/t-168267.html ffmpeg.zeranoe.com/forum/viewtopic.php?f=17&t=1851 For the former, simply copy the "-af" switch and its parameter, while for the latter, copy the "-clev" and "-slev" switches.

Tonight is the first time I have used it and I see I have a lot to learn. Is there a cheat sheet or anything for most used commands?

@NERDfirst

8 жыл бұрын

+Jessie Wilson I haven't come across a cheat sheet myself, to be honest! All I've done is, through experience, found a set of features I use the most often, and then internalize those. For example -b:v and -b:a to set bitrate (or -crf for certain codecs). Occasionally I use -vcodec as well because sometimes I want to produce MJPEG, for example. For the more complex tasks, I just build the command into a batch file and run it with a double click.

This was so helpful and simple! One extra tip for comment readers: it words best when the file name has no spaces.

@NERDfirst

1. I have another question: i did a screencapture using OBS of a video, getting a .flv video file. I use this technique to convert it to a .avi using the quantizer (-q 1) command. I tried 0/1/10/50. The only acceptable values were 0 and 1. The others looked like 240p versions of the original. But even the 0/1 ones were just okay, they were visibly worse than the original .flv file. In this video you only say u can set the q value to single or double digits. Is the lowest number and highest quality quantizer value 0 then? Or is there a higher quality setting I can use? the highest quality quantizer should be the same as the highest bit rate in the finer control, no? Also I don't understand what the bitrates I can use are, is there a guide you can suggest? like my vse allows me to export audio bitrates up to 384kbps and it uses ffmpeg to do it. SO its 384 the max audio bitrate? But then what's the max video bitrate value I can use? again in my vse its 10000 but im not sure if that value is correct or if there's a better one. Also the -q 0 sized file was 70mb whereas the original .flv is only 26mb....but the original still looks much better? why? 3. Next there's 1 bit i'm missing. The commands you mentioned were for changing the container, like from .avi to mp4, etc. What happens with the codec....? Do these commands copy the codec of the original and use it in the new container? Also I'm assuming changing the container re-encodes everytime, is this correct? IF I'm changing to a container that doesn't support the original codec does it give you an error or what happens then (like say I had a .wav file in a .avi and made it into an ,mp4, how does ffmeg work then. im assuming .wav can't be stored in .mp4 containers) ? 2. Do filters re-encode? say i just want to half the volume, is it gonna re-encode the video? How would u tell if something re-encodes?

@NERDfirst

6 жыл бұрын

1. Regarding the quantizer setting, not all codecs use the -q flag. I have no experience with FLV, but see if there's a different flag or setting that would work better. The range of quantizer values also depend on the codec. For bitrates there isn't really a "maximum" unless your codec enforces one. Of course, beyond a certain point you won't get any more perceptible quality. I don't really have any guidelines for you, go with your gut! For me, if it "feels" okay it's okay. If you're still worried, you can search the net for some common values. As to your last point, higher file size doesn't correspond to higher quality (the other way tends to be more likely, but even then it's not always the case). I don't know what was done to the video exactly, but every bit of processing will clobber it further. 2. You can take it that all FFMPEG operations re-encode unless you explicitly tell it not to. 3. When codecs are not specified, FFMPEG picks one for you based on the container you've selected (it will of course pick a valid one), and your media is re-encoded to that codec. I have not changed codecs very much to be honest but I'm sure FFMPEG will complain if you do something that's invalid or incompatible.

Excellent guide, thank you :)

Hello and thank you for your comment! I'm glad to hear! Have fun with FFMPEG =)

For the filter parameters at 8:54, I think there is is shortcut ( -af volume=2 ). -a for audio -f for filter Similarly to add filter to a video, you can do, for example -vf scale=-1:720, to shrink or expand a video to 720P -v for video -f for filter, scale is the filter function to scale the video input -1:720, -1 means to keep the original ratio and adjust width automatically, 720 sets the height of the video to 720px.

Hello and thank you very much for sharing! Yeah, there are many shortcuts available in FFMPEG. Unfortunately the video was already running a little long and I was saving those for a future video =P Good to have a reference here though!

Great, Thanks for your efforts.

+Icc0612 But, when I try to encode *.ass subtitle into *.mp4 file. It just didn't work. I've used static build as you mentioned. And command line was ... ffmpeg -i video.mp4 -vf "ass=subtitle.ass" out.mp4 Do you have any thought?

+Shawn Greene Hello again! I have to confess to having zero experience with subtitles, but it seems that there are a few hoops you need to jump through to get .ass subs to work correctly. Check out this guide. I hope it's not too outdated. trac.ffmpeg.org/wiki/HowToBurnSubtitlesIntoVideo
