The practical use of this information has been integrated into the "zoomcalc.c" program, which uses the math in this document to do the calculations that videotrans needs. This file is only present in the source directory, it will not be installed anywhere. Assumptions ----------- - The source image has dimensions SX by SY - The source image has aspect ratio SA, which can be expressed as a fraction SAX/SAY. The default source aspect ratio, if none is given, is SX/SY, which means that the source pixels are perfectly square. - The destination image has maximum dimensions DX by DY. - The destination image has aspect DA, which can be expressed as a fraction DAX/DAY. Goal ---- What we want to do is to determine new dimensions for a zoomed image that preserves the source aspect ratio and fits into the destination image as well as possible. Definitions ----------- There are two types of zooming. One is called letterboxing, which means that the source image is preserved entirely, and if the aspect ratios of the source image and the destination image are different, that black borders are created on either the top and the bottom or on the left and the right side of the destination image to make it exactly DX by DY in size. The other zooming method is called panscan, which means that part of the source image will be cropped to make it fit into the destination image without creating any black borders. Either some part of the top and bottom of the source image will be cropped or some part of the left and right of the source image will be cropped. Pixel sizes ----------- Because the source image has dimensions SX by SY and has aspect ratio SAX/SAY, it is possible that pixels are not perfectly square. The aspect ratio of one pixel can be expressed as follow: SPX SY * SAX SP = --- = -------- SPY SX * SAY That is to say, if the height of a pixel is defined as 1, then the width of that pixel will be equal to SP. For example, if we want to know what a pixel looks like in the PAL DVD 720x576 mode (in the aspect ratio 16:9), we would work out: SP = (576 * 16) / (720 * 9) = 1.422222 That means that a pixel in this DVD mode is 1.422222 times as wide as it is tall. Of course, the same holds for the destination image: DPX DY * DAX DP = --- = -------- DPY DX * DAY ZOOMING AND CROPPING -------------------- Because the pixel sizes of the source and the destination are potentially different, we need to know how to zoom and/or crop the source image to get to the destination image. We can do this by dividing the aspect ratios by eachother. Depending on whether we're letterboxing or panscanning, we need to create black border or chop off part of the source image, respectively. The way in which we calculate what we want is as follows: If we are letterboxing (creating black borders): CX = SX CY = SY If (SAX / SAY) < (DAX / DAY) (the picture would be too narrow): ZX = ((DAY * SAX) / (DAX * SAY)) * DX ZY = DY Otherwise (the picture would be too wide): ZX = DX ZY = ((DAX * SAY) / (DAY * SAX)) * DY Otherwise (we are panscanning, thus cropping the image): ZX = DX ZY = DY If (SAX / SAY) < (DAX / DAY) (the picture would be too tall): CX = SX CY = ((SAX * DAY) / (DAX * SAY)) * SY Otherwise (the picture would be too wide): CX = ((DAX * SAY) / (DAY * SAX)) * SX CY = SY Examples -------- Say you have an AVI file with a video in it of which the dimensions are 576x432 and aspect ratio 4/3. You want to transcode the AVI file onto a DVD in 720x576 PAL DVD mode in 16/9 aspect ratio. What should the parameters to the encoder be if we want to letterbox the video (so that the entire image is displayed)? We calculate whether (SAX / SAY) < (DAX / DAY) (4 / 3) < (16 / 9) This is true, so we do: CX = SX = 576 CY = SY = 432 ZX = ((9 * 4) / (16 * 3)) * 720 = 540 ZY = DY = 576 And thus, the scaler should not crop the image and zoom the image to 540x576 and create black borders on both sides to expand the total image to 720x576. Another example, with a source video of 480x576 in 4:3 mode. We want to encode this movie in 720x576 PAL DVD in 4:3 mode. What should the scaler do? We calculate whether (SAX / SAY) < (DAX / DAY) (4 / 3) < (4 / 3) This is not true, but the picture would fit perfectly. We can choose either of the two formulae. We choose the first one, but the second one will yield exactly the same results. CX = SX = 480 CY = SY = 576 ZX = ((3 * 4) / (4 * 3)) * 720 = 720 ZY = DY = 576 And thus, the scaler should not crop the image and zoom the image to 720x576, which just happens to be exactly the desired destination size. Another example, with a source video of 640/272 with square pixels. We want to encode this movie in 720x576 PAL DVD mode in 16:9 mode, using the panscan method to chop off the superfluous sides. What should the scaler do? We calculate whether (SAX / SAY) < (DAX / DAY) (640 / 272) < (16 / 9) This is not true, so the picture would be too wide if we would stretch it so far that there would be no borders on any side. Because we want to use the panscan method to get rid of the superfluous sides, we calculate: CX = ((DAX * SAY) / (DAY * SAX)) * SX = ((16 * 272) / (9 * 640)) * 640 = 484 CY = SY = 272 ZX = DX = 720 ZY = DY = 576 And thus, the scaler should crop the image to 484x272 and then zoom the image to 720x576, which just happens to be exactly the desired destination size. videotrans-1.6.1/configure.ac0000664000175000017500000000566611625240271014712 0ustar svensvenAC_INIT([videotrans], [1.6.1], [videotrans@berkvens.net], [videotrans]) AC_PREREQ([2.53]) AC_REVISION([$Version:$]) AC_CONFIG_SRCDIR([aspects.txt]) AC_CONFIG_AUX_DIR([ac-support]) AC_PROG_INSTALL [videotrans_warnings=""] AC_CHECK_PROG([MPLAYER], [mplayer], [yes], [no]) if test x$MPLAYER = xno ; then AC_MSG_ERROR([mplayer is required, please get it from http://www.mplayerhq.hu/]) ; fi [mplayer_version="`mplayer | head -1 | sed 's,^[^ ]* \([^- ]*\).*,\1,'`"] if test x$mplayer_version != x1.0pre7try2 ; then if test x$mplayer_version != x1.0rc1 ; then if test x$mplayer_version != x1.0rc4 ; then AC_MSG_WARN([This program is known to work correctly with mplayer version 1.0pre7try2, 1.0rc1 and 1.0rc4.

'video' will duplicate or drop frames to adjust the framerate (which will make the movie jerky in some situations), 'audio' will adjust the pitch of the audio track so that it runs synchronized with the movie. 'auto' will make the decision for you. -a aspect Either 16:9 or 4:3 (how to encode the video). Or you may specify 'auto' (default) for automatic selection. -A src_aspect Specify the aspect ratio of the source if it is not encoded correctly in the source. The format is X:Y, for example 4:3 or 41:18. Or you may specify 'auto' (default) for automatic detection from the source. -m mode Either pal, ntsc or auto (default). -c codec The audio codec, either 'mp2', 'ac3' or 'auto' (default). Currently, the 'auto' setting always chooses 'ac3'. -q quality Select either 'low', 'normal', 'high' or a bitrate in kilobits per seconds. This is the MAXIMUM bitrate that the video encoder will use. -Q bitrate Controls the bitrate for the audio output. Normally, this is automatically determined from the parameters of the output audio format and the number of channel, but you can override the automatically selected bitrate using this option. Specify the number of kilobits per second that the audio should use. You may combine this option with the -c option to force a certain audio encoding. The default is 'auto', which means autodetection. -o output_dir Write the .m2v and .mp2/.ac3 files into an alternative directory instead of the same directory in which the source(s) reside. -M Multiplex the output audio and video together (if you do not specify this, an .m2v and .m2a file will be generated for each input movie) -b This tells mplayer that any AVI headers that are encountered are broken and that they should be ignored when determining the audio-video sync delay. This activates mplayer's -nobps option. -O options You may specify specific options to pass to mplayer. Be sure to quote the options appropriately: the options should be supplied surround by quotes, and the options should be entered as they would have been on a normal mplayer command line.

You will use this after you've run dvdauthor to create a DVD image to clean up all the temporary files that this program left behind.

This may be anything, for example . -t title Directory containing the title sequence, which should have been created by movie-make-title or movie-make-title-simple. -T XxY Display movie picture-in-picture previews in a grid of X by Y (normally automatically detected by the program). -s start Start picture-in-picture movie previews at approximately this number of seconds instead of at the beginning of the movie. You should probably also use this option when the title sequence was generated with the "static preview images" option (using the -n option for the movie-make-title and movie-make-title-simple programs). -c interval Sets how long a chapter lasts in the movies.
