Temp:Video encoding manual
What is this?
To encode a video is: Format a video source in a determinated type of data in order to be read(decoded) by a player.
Most formats are compressed ones, which means you'll have some loss of quality. The others which are not compressed provides a image/audio without loss.
To figure out this we'll use a daily example on our lives: When you press Print Screen you're capturing(and enconding) all the pixels displayed on your monitor(who are decoded, on another words, understandable), these ones can be read on the famous "Paint Brush" for instance, and then saved on the bigger lossless BMP files(an uncompressed format) or the smaller and lossy JPEG(a compressed format).
The MP3 Tools Decoder/Encoder
The MP3 Tools includes a decoder called AMV Video Player, and a encoder named AMV Video Convert Tool wich will able you to watch AMV files on your computer and compress then to play into a S1MP3 Video Player(MP4) respectively. Both ones were badly translated, so we're developing a correct language file.
You'll need DirectX 9.0 and Windows Media Player 9.0 installed on your computer beyond the necessary codecs, wich ones can be found into ffdshow codecs pack. So you must have Windows or a simulated Kernel Module running at Linux. I was almost forgetting, you'll need a computer! lol :D
Encoding a video file with the AMV Convert Tool is really easy, as you'll see below.
- First, open it from your Start menu -> Programs -> MP3 Tools 3.68 -> AMV Convert Tool
- Then select the video file you want to convert, the Input File
- After you have selected the Input File, you will now choose where you'd like to save you AMV video file.
- Afterwards select the video files on the list like the image below,
- In the Property Setting panel you will now choose the settings that best fits into your player:
- The Video Settings:
Mode0: The image will be reduced by it's source defined height(contending the proportion) and then clipped left and right to fit the width you have already chosen;
Mode1: The image will be reduced by it's source defined height(contending the proportion) and then compressed horizontally to fit the width you have already chosen(this mode might cause distortion);
Mode2: The image will be reduced(mantaining the porportion) on it's height and width and then clipped vertically and horizontally in order to obtain a clear image;
Mode3: The image will be reduced in the box mode, in other words, the image is wrapped to fit a bigger box, and then masked by a smaller one.
- According the aplication programmer this function was not activated yet. However, keep it marked.
- The Audio Settings:
- This choice box will be disabled due to the audio encoder doesn't be capable(programmed) to reach higher frequencies and so your player.
- If you want to substitute the original movie audio, you have to use a WAV source. If you don't have a WAV file, use an audio conversor/editor to obtain it.
- According the aplication programmer this function was not activated yet. However, keep it unmarked.
- After you have selected the configurations that best fit on your player press OK.
- Now just click the Begin button to begin the process.
- When the progress bar reaches 100% the encoding will be done and the AMV Player will open and play your converted files.
Optimizating your video file using Virtual Dub
Virtual Dub is a free open source video encoder which provides you a better video adjusting. Using this program is worth because the AMV Convert Tool doesn't have a good FPS converter, nor a image cropper, sharpener, and more related video stuff.
Setting the FPS
To avoid laggy videos on your player, setting the FPS may offer a better quality.
First, click Video from the upper menu and then Frame Rate .

Then Select the same fps of converter (high: 16fps
medium: 12fps low: 8fps)
Now encode the movie in virtualdub and then in amv Converter
