| Hi, I have following problem. I have one avi-file, with a filesize over 6 GB. I load this file into VirtualDub, cut some frames, and save the audio and video stream with direct stream copy. The result file then is ca. 5 GB. Then when i load this result file for example with the Microsoft media player I always get the error message from the media player, that the audio type is not supported. When I save this file into different segments with 2 GB, I didn't get this error. Has virtual dub problems with files over 2 GB? My OS is windows 2000, and my filesystem is NTFS. tom |

| AVI > 6 GB ?? I am not completely mistaken than this is not possible. Even OpenDML AVIs should belimited to 2 GB if i remember correctly ..... thats why Vdub is offering the 'save segmented AVI' function with a predefined max size of 2000 MB ... |

| OpenDML explicitly provides a new indexing mechanism that can handle 64-bit file pointers, so appropriately extended files have no 2GB limit. VirtualDub can read OpenDML-indexed files up to about 256TB; it can write files past 2GB but will have some trouble above around 64GB due to internal limits. There is a bug in the OpenDML writer that produces bad duration values in the index; it appears that some versions of DirectShow do not like this. I am fixing this in 1.4.11, when I get it finished. |
