How to change resolution of divx movie? Hi, I have an avi video which is 640x480 resolution. It is originaly only 650mb. I need to change it to 640x300 at the most. Thanks for any time or help. 1) Download AVIUtil: AviUtil 2) Unzip the file aviutl98d.zip, launch aviutl.exe. After that, just close it. 3) Aviutl.ini file will appear in the same folder. Open it using notepad. Go to the end of file, move cursor at the last position and type the following: [system] resource=English 4) Save aviutl.ini. Now, launch aviutl.exe again. Click File -> Open. Find and open your divx file. 5) Click Setting -> Resize -> Custom. Enter 640x300 (or any other values). 6) Choose Video Codec (XviD is recommended). Clear the check box (no recompress), because actually we want to recompress video. 7) Do not choose audio codec, but make sure that no recompress option is checked here, for audio. 8) Enter output file name. Click SAVE. Wait several minutes(hours). Done! You have resized your divx movie.  Try Commercial Solution:  Resize movies using Vidmex.
