| I want to create a video file that can be burned as an NTSC compatible and i using vitualbud 1.77 to cornverted PAL DVD video is typically 720x576 at 25fps. NTSC is generally 29.97fps and 720x480, by Slowing down the 25fps video from the PAL file to 24fps gets you a viewable result without too much complex math. To make this conversion but it crash the inf said An out-of-bounds memory access (access violation) occurred in module 'xvidcore'... ...reading address 86FE7A12... ...while running thread "Processing" (thread.cpp:152). anyone has any idea how to avoid this thank you |

| ok I try it this say I have format restritionses width must be a multiple 2 height must be a multiple 4 valid depths 24 32 any ideas what it means |

| The resolution of the video has to conform to those limits - IE you cant have 123 x 543 because they are odd numbers. The 24/32 is the colour depth of the video (24 bit and 32 bit). |

| It means you have to choose a resolution for your video that meets certain multiples. For instance, "height must be a multiple of 4" means you could use 720x576, since 576 is divisible by 4, but not 720x577, since 577 is not divisible by 4. If you don't get these right, then you'll probably get an error from the video codec when you try to compress. The "valid depths 24 32" means that the codec accepts 24-bit and 32-bit RGB formats. It's very rare that you have to care about this, because VirtualDub defaults to fairly compatible settings. |
