-===== Examples ===== 
- 
-==== Converting AVI files to VCD ==== 
- 
-Encoding the audio with libavcodec: 
- 
-<​code>​ 
-avidemux2 --load input.avi --audio-process \ 
---audio-normalize --audio-resample 44100 --audio-codec MP2 \ 
---audio-bitrate 224 --output-format PS --video-process \ 
---vcd-res --video-codec VCD --save output.mpg --quit 
-</​code>​ 
- 
-Encoding the audio with TWOLAME: 
- 
-<​code>​ 
-avidemux2 --load input.avi --audio-process \ 
---audio-normalize --audio-resample 44100 \ 
---audio-codec TWOLAME --audio-bitrate 224 \ 
---output-format PS --video-process --vcd-res \ 
---video-codec VCD --save output.mpg --quit 
-</​code>​ 
- 
-==== Re-encoding a soundtrack to MP3 VBR ==== 
- 
-First save the audio in WAV format: 
- 
-<​code>​ 
-avidemux --load input.avi --audio-process \ 
---audio-normalize --audio-resample \ 
---save-uncompressed-audio /​tmp/​videocd.wav 
-</​code>​ 
- 
-Then encode it with Lame seperately: 
- 
-<​code>​ 
-lame /​tmp/​videocd.wav -vbr -v -V 4 \ 
-/​tmp/​videocd.mp3 
-</​code>​ 
- 
-Reload the MP3 and save AVI: 
- 
-<​code>​ 
-avidemux --load input.avi --external-mp3 /​tmp/​videocd.mp3 \ 
---audio-map --save /​tmp/​new.avi 
-</​code>​ 
- 
-The audio map is very important as we have generated a VBR MP3. Else expect async big time! 
- 
-It is just an example as you can encode to MP3 VBR using the GUI directly. 
- 
-==== Batch convert MP4 files to AVI ==== 
- 
-This example will open the MP4 file safely (if it contains [[tutorial:​H.264]] video or anything else, it does not matter). Then it will save the file into an AVI container, with no modification to the video or audio. The command in general is this:  
- 
-<​code>​ 
-avidemux2 --force-alt-h264 --load "​video.mp4"​ \ 
---save "​video.avi"​ --output-format AVI --quit 
-</​code>​ 
  
-Here is a small script to process all the MP4 files in the current directory: 
  
-<code bash> 
-#!/bin/bash 
-VAR="​files.txt"​ 
-ls *.mp4 | sort > $VAR # Collect the files in the current directory 
-cat $VAR | while read line; do  # Loop read the filenames from the file 
-  INPUT=$(echo ${line}) # Grab the nxt new filename 
-  OUTPUT=${INPUT%.*4} # Remove shortest match of characters between the '. ' and the '​4'​ at end of string 
-  OUTPUT+="​.avi"​ # Append new extension 
-  avidemux2 --force-alt-h264 --load "​$INPUT"​ --save "​$OUTPUT"​ --output-format AVI --quit ​ 
-done 
-rm $VAR # Remove the text file with the file names 
-</​code>​
