can someone assist me to change the aspect ratio of avi file with MPEG4Modifier. i am new to this software & cant find a guide the problem is when i play this on windows media player, the movie is all stretched up & when i open it with virtualdub & then change the aspect ratio to 16:9 (wide screen), the video looks just perfect. (actually from where i downloded this, there was a note stating "set aspect ratio manually to 16:9") any help will be much appreciated & i have a few more files with exactly the same problem but they all have different frame sizes, like one is 512*384 & so on. These are the screen caps: this is the info from mediainfo: Code: General Complete name : E:\abcd.avi Format : AVI Format/Info : Audio Video Interleave File size : 699 MiB Duration : 1h 38mn Overall bit rate : 988 Kbps Writing application : VirtualDubMod 1.5.4.1 (build 2178/release) Writing library : VirtualDubMod build 2178/release Video Format : MPEG-4 Visual Format profile : Streaming Video@L1 Format settings, BVOP : Yes Format settings, QPel : No Format settings, GMC : No warppoints Format settings, Matrix : Custom Codec ID : XVID Codec ID/Hint : XviD Duration : 1h 38mn Bit rate : 842 Kbps Width : 624 pixels Height : 464 pixels Display aspect ratio : 4/3 Frame rate : 29.970 fps Resolution : 24 bits Colorimetry : 4:2:0 Scan type : Progressive Bits/(Pixel*Frame) : 0.097 Stream size : 596 MiB (85%) Writing library : XviD 1.0.2 (UTC 2004-08-29) Audio Format : MPEG Audio Format version : Version 1 Format profile : Layer 3 Codec ID : 55 Codec ID/Hint : MP3 Duration : 1h 38mn Bit rate mode : Variable Bit rate : 131 Kbps Nominal bit rate : 128 Kbps Channel(s) : 2 channels Sampling rate : 48.0 KHz Resolution : 16 bits Stream size : 93.0 MiB (13%) Alignment : Aligned on interleaves Interleave, duration : 24 ms (0.72 video frame) Interleave, preload duration : 273 ms Writing library : LAME3.90.

It works quickly just try the various options till you hit the right combo. Start first with Display AR-> tick 16:9. If that doesn't do it try ticking (changing) one of the NTSC options in Pixel AR also.
