-Introduction
-============
-
-With home made videos or screencasts, we often find a constant noise in our recording due to electric wiring, fan, choke coil of fluorescent
-lamp etc. This could be irritating.But fortunately, these noises can be easily detected and can be removed with GUI based tools, such as
-Audacity.
-To use any GUI based tool, we need to extract audio manually and then feed it to the software, once done we have to again join the noisefree
-audio with the video. This is OK with 1 or 2 files. But to for automating each step and to handle multiple files we need a simple script.
-
-One can simply use `sox` and `ffmpeg` commands shown below in given order to get the same result(see `Working`).
-
-
-UPDATE for 14.04
-----------------
-
-Install **libav-tools** and **sox**.
-
-Run as ::
-
- $ bash noNoise.sh noisyVideo.mp4 noise-reduction-factor
-
-This will create an backup file of original video in **/tmp**
-and noisefreeVideo in **pwd**.
-
-Example ::
-
- $ bash noNoise.sh Kazam_screencast_00000.mp4 0.2
-
-It will create **noisefree_Kazam_screencast_00000.mp4.mp4** in **pwd**
-and a backup of original video in **/tmp/orig_Kazam_screencast_00000.mp4**
-
-This is just an early fix, will add more features soon.
-
-Please raise issues for any bugs or email me for feature requests.
-
-Also, I recently came across **Kazam** package (available in repositories),
-its a good screen recorder with most needed keyboard shortcuts, such as
-
-* start recording: Super + Control + r
-* pause recording: Super + Control + p
-* finish recording: Super + Control + f
-* show Kazam: Super + Control + s
-* quit: Super + Control + q
-
-Required packages (Upto Ubuntu 13.10)
--------------------------------------
-
- * sox
-
- * ffmpeg
-
- * ffmpeg2theora
-
- * libmp3lame0
-
- * Linux machine with default python
-
-
-
-Usage
------
-
-### Remove noise from a single file
-
-
- $ python noNoise.py VideoWithNoise.ogv CleanVideo.ogv
- (source file) (destination file)
-
-(OR)
-
- $ python noNoise.py VideoWithNoise.ogv CleanVideo.ogv 0.21
- (source file) (destination file) (noise factor)
-
- The third argument is optional(Noise factor). The scale spans from
- `0.0` to `1.0`. Zero means no noise supression and 1.0 means full. The full
- scale is avoided. Best optimum result is found between `0.2` to `0.3`. By default
- script will take `0.26`. One can experiment with noise factor to get best noise
- free video.
- NOTE: Careful, destination file will be overwritten if exist in given path.
-
-
-
-### Remove noise from all files inside a directory
-
-
- $ python noNoise.py allNoisyFiles allCleanFiles
- (source dir) (destination dir)
-
-(OR)
-
- $ python noNoise.py allNoisyFiles allCleanFiles 0.21
- (source Dir) (destination dir) (Noise factor)
-
-NOTE: Please don't use any '/' after directory name. It will spit error.
-The fix is possible, but I don't want to spend time on it. This script is dirty
-but useful(atleast for me). When I find time, I will surely modify it. Meanwhile
-you all are welcome to add modifications.
-
-
-
-Working:
--------
-###1. Extracting video in less compressed format
-
- ffmpeg -i 1.ogv -sameq -an 2.wmv
-
- Extracting video in wmv format for easy editing(less compressed
- than mp4,ogv,avi). We can leave the video intact and combine the
- noiseless audio later to it, but it will hamper the video quality
- of the newly joined video.
- The size of this 'wmv' will be approximately 5 times than that of
- original 'ogv' video.
-
-
-###2. Extracting audio in less compressed format
-
- ffmpeg -i 1.ogv -sameq 2.wav
-
- Extracting audio in wav format for fast & easy editing.The size of the
- `wav` audio file will be approximately 8 times larger than the original.
-
-
-###3. Getting noise profile
-
- sox 2.wav -t null /dev/null trim 0 0.5 noiseprof myprofile
-
- Creating a noise profile of original audio at 0 to 0.5 second.
- One can change this duration if required. In most cases the
- standard noise is evenly distributed throughout the recording(eg:
- fan, PC etc), so the default 0 to 0.5 value will do the trick.
-
-###4. Converting audio according to noise profile
-
- sox 2.wav 2-noisefree.wav noisered myprofile 0.26
-
- Creating a noisefree audio based on our noise profile. The value
- `0.26` is important. This is scale for noise removal. 0 means no removal
- and 1 means full removal. The full removal will supress most of the
- orginal audio too. So as per my R&D, I found `0.26` to be most optimized
- one for noise removal.
-
-
-###5. Combining back audio and video
-
- ffmpeg -i 2-noisefree.wav -i 2.wmv -sameq vid.wmv
-
- Merging new noiseless audio and old video together.
-
-
-###6. Final conversion
-
- ffmpeg2theora vid.wmv -o vid.ogv
-
- Now converting wmv into our favorite ogv format. This will create a
- `vid.ogv` of almost same size that of original video.
