EMoC - Easy Movie Converter
Emoc is simple application, front end for "ffmpeg" and "mencoder" command line programs, that enables you to convert video files from one format to another, resize and resample them (usually to deminish video file in size on disk).
Additionally, Emoc can join various files into one video file. It is designed to be simple to use.
Profiles
----------------------------------------------
When you start Emoc for the first time, there will be no profiles and you will not be able to do anything with it. So, at least one profile must be created. Profiles are designed to keep different jobs handy. For example, you can create a profile to prepare files for upload on "youtube", other to store family videos etc, each job with different settings, as necessities are different.
There are 3 types of job that can be done with Emoc. You can join videos, convert videos and convert and join videos in one pass.
To join (only join) videos, when creating new profile, you should just check "Join" checkbox and leave all other settings unchanged. There is just one catch here: All video files that you wish to join must be of same type and codec.
This is useful if your video camera makes various videos (according to how much you press recording on and off), and you wish to join them into one video file, preserving the quality.
If you change any other setting, Emoc will convert video files, and if "join" checkbox is checked, it will join them into one file, and at the end, delete "transitional" (converted) files as final file is created.
If join is selected, in any case, converting or not, when you initiate process, Emoc will ask you for the name of final output file.
Output format: Choose between available video formats. If unsure, set it to MPEG4.
Bitrate: If you change it to "SET", you need to provide bitrate. Higher it is, higher is the quality and bigger the file. There is no "optimal" value, you need to discover what is best for desired job. For example, I use 4096 for youtube, as my camera makes it just a bit less then 10000 which makes files very very big. If you wish to keep your video on DVD, 4096 is not a good option. You should set up higher value, e.g. 9216 or so. Yes, file will be much bigger, but quality also.
Size: If you change it to "SET" you will need to provide width and height for output video file. Beware, wrong values (wrong aspect ratio) will distort your movie.
Additional parameters: Additional parameters are for experts. Please look at ffmpeg manual. Important is that you must not put parameters for bitrate, size and output file (-b, -s and -o). Any given parameters will be put just before "-o" parameter. If you don't know what you are doing, leave this field blank.
Note: When you change output format to FLV, Emoc will automatically put "-ar 44100" parameter. That is because FLV format supports only few sample rates, and converter must force one of them. Wrong sample rate will fail in conversion. You can choose 22050 or 11025 or any other by manual, but sound is not something that will significantly economize your space, especially if in mp3 format.
MAIN SCREEN
----------------------------------------------
In main you have buttons to control files that will be converted/joined. When you press "START" button, no matter if some files are selected, all files in list will be processed.
Output directory is where converted files will be stored. If empty, it will be automatically placed to your home directory.
