FFMPEG and codes

[LazyPooky]

Download for windows:

https://ffmpeg.zeranoe.com/builds/

Choose:
Version: 3.4.1 (latest version today)
Architecture: Windows 32 or 64bit
Linking: Static
--> and use the Download Built link.
extract the file, and you will find ffmpeg in the bin directory

In Windows Explorer go to a directory with the file you want to convert (copy the ffmpeg file to that directory also!), hold SHIFT down and right click in the area where the file is located -> command prompt

If you have the black command window, now you can use one of the codes below, or find your own code depending on what you want to do with the file(s).



BATCH extract 5 channel audio

FOR /F "tokens=*" %G IN ('dir /b *.*') DO ffmpeg -i "%G" -vn -ar 48000 -map 0:a:0 "%~nG0.wav" -map 0:a:1 "%~nG1.wav" -map 0:a:2 "%~nG2.wav" -map 0:a:3 "%~nG3.wav" -map 0:a:4 "%~nG4.wav"

BATCH Audio conversion to WAV

FOR /F "tokens=*" %G IN ('dir /b *.*') DO ffmpeg -i "%G" -vn -ar 48000

FOR /F "tokens=*" %G IN ('dir /b *.*') DO ffmpeg -i "%G" -vn -ar 44100

* NON-BATCH Conversion: remove the [FOR /F "tokens=*" %G IN ('dir /b *.*') DO] - part

Rotate

ffmpeg -i input.mp4 -vcodec libx264 -preset medium -crf 24 -threads 0 -vf transpose=1 -acodec copy output.mkv

Streaming from a website with a *.m3u8 link

ffmpeg -i "http://webriplink.m3u8" -c copy output.mp4

* output.mp4 or output.ts

FFMPEG and codes

For stream episodes?

FFMPEG and codes

For streamed episodes or any other episode, to extract the different audio languages, and more codes.

This is for back-up codes, and I add more later.

FFMPEG and codes

conversion from FR25 to FR23.976

Single VIDEO file

ffmpeg -i FILE.XX -b:v 5M -r 23.976 -filter:v "setpts=1.0427*PTS" -c:v libx264 FILE.YY

i.e. FILE.XX = S4E12.ts and FILE.YY = S4E12.mp4 ,
or FILE.XX = S4E12.mp4 and FILE.YY = S4E12_FR23.976.mp4
etc.

Multiple VIDEO files in folder:

FOR /F "tokens=*" %G IN ('dir /b *.mp4') DO ffmpeg -i "%G" -b:v 5M -r 23.976 -filter:v "setpts=1.0427*PTS" -c:v libx264 "%~nG .mp4"

You can:
[change the .mp4 input and output file extension]
[change the 5M bitrate if you want lower (low bitrate) or higher (high bitrate) quality]
[change the libx264 encoder] (not recommend)
[remove the space in "%~nG .mp4" if you use another extension as output file]


Single AUDIO file

ffmpeg -i input_FR25.mp4 -filter:a "atempo=0.959" -vn output_FR23976x.mp4

* works with *.wav files too.
* audio quality is worse because of hick-ups, so it's not recommended to do this and you better use the original FR23.976 audio if available.

Audio from FR23.976 > FR25
(wav file, and batch processing)

FOR /F "tokens=*" %G IN ('dir /b *.wav') DO ffmpeg -i "%G" -filter:a "atempo=1.0427" -vn "%~nG .wav"

Re: FFMPEG and codes

WinFF is a converter that uses the FFMPEG engine but has a nice GUI. It can convert all audio and video files to everything you want, it has built in presets and you can change or add codes if you want.
Remember that it converts files to another format. If you don't want that for your video files, you better use the remuxers.
For audio files it's a great tool (like flac to wav, or mp3 to wav etc.)
Free to use.

Re: FFMPEG and codes

there are plenty online services that do the same...this one e.g.

Re: FFMPEG and codes

https://www.files-conversion.com/

only if you're a noob

it's seriously drama to convert every single file one by one
uploading 1.5GB files takes forever and later, you need to download the file.. I've converted 100 files local instead of waiting for 1 file finally converted online
there's probably an upload limit
there is no option for multiple channel extraction
no bitrate
where is the framerate converter?
what's the engine used? x264 or..?
etc.

Conclusion: trash :flush:
