Are you new to LinuxQuestions. MPlayer provides a crop detection filter that will determine the crop rectangle -vf cropdetect.
Run MPlayer with -vf cropdetect and it will print out the crop settings to remove the borders. You should let the movie run long enough that the whole picture area is used, in order to get accurate crop values.
Then, test the values you get with MPlayerusing the command line which was printed by cropdetectand adjust the rectangle as needed. The rectangle filter can help by allowing you to interactively position the crop rectangle over your movie. Remember to follow the above divisibility guidelines so that you do not misalign the chroma planes. In certain cases, scaling may be undesirable.

Scaling in the vertical direction is difficult with interlaced video, and if you wish to preserve the interlacing, you should usually refrain from scaling. If you will not be scaling but you still want to use multiple-of dimensions, you will have to overcrop.
Do not undercrop, since black borders are very bad for encoding! Because MPEG-4 uses 16x16 macroblocks, you will want to make sure that each dimension of the video you are encoding is a multiple of 16 or else you will be degrading quality, especially at lower bitrates. You can do this by rounding the width and height of the crop rectangle down to the nearest multiple of As stated earlier, when cropping, you will want to increase the Y offset by half mplayer could not find working vidix difference of the old and the new height so that the resulting video is taken from the center of the frame. And because of the way DVD video is sampled, make sure the offset is an even number.
In fact, as a rule, never use odd values for any parameter when you are cropping and scaling video. If you are not comfortable throwing a few extra pixels away, you might prefer to scale the video instead.

We will look at this in our example below. You can actually let the cropdetect filter do all of the above for you, as it has an optional round parameter that is equal to 16 by default.
Also, be careful about "half black" pixels at the edges. Make sure you crop these out too, or else you will be wasting bits there that are better spent elsewhere. After all is said and done, you will probably end up with video whose pixels are not quite 1. You could calculate the new aspect ratio manually, but Mplayer could not find working vidix offers an option for libavcodec called autoaspect that will do this for you.
Absolutely do not scale this video up in order to square the pixels unless you like to waste your hard disk space. Scaling should be done on playback, and the player will use the aspect stored in the AVI to determine the correct resolution. Unfortunately, not all players enforce this auto-scaling information, therefore you may still want to rescale.
If you will not be encoding in constant quantizer mode, you need to select a bitrate. The concept of bitrate is quite simple. It is the average number of bits that will be consumed to store your movie, per second. Normally bitrate is measured in kilobits bits per second. The size of your movie on disk is the bitrate times the length of the movie in time, plus a small amount of "overhead" see the section on the AVI container for instance. Other parameters mplayer could not find working vidix as scaling, cropping, etc. Bitrate does not scale proportionally to resolution. There are two reasons for this:. Artifacts appear on the scale of blocks 8x8.

Your eye will not see errors in small blocks as easily as it sees errors in large blocks assuming you will be scaling both to fullscreen. Theoretical : When you scale down an image but still use the same size 8x8 blocks for the frequency space transform, you move more data to the high frequency bands.Cannot test OS support for SSE, disabling to be safe.
