I have a similar interest in using ffdshow encoding to Mpeg2 from Vdub. Te reason is i have lots of .h264 (hundreds to thousands) HD files that I need to batch process to encode them to Mpeg 2. I've solved most of the process butt.... When I process a directory on VirtualDubMod's Job Control I get .AVI files that do not work (I get an "Unknown file format FFDS" error msg.) Maybe ffds is messing up de FOURCC code?? I tried seting Output in FFDSHOW to "Store frames to external file" => "RAW frames" (as sugested somewhere) but I can't figure out what to write on the location fiel in order for the batch process to work ok and create 1 mpeg file for each original .h264 AlreadyTried using: D:\outputFolder\ D:\outputFolder\*.mpg An avi file is created while the encoding is taking place and when finished that avi is transformed into a handler i guess (goes from several MBs to 18kb) but no other file is found. I also tried D:\outputFolder\%i to see whjat happenned, same as before but ended with the avi handler and thousands of 22kb .mpeg files (which I guess are separated frames) I guess it should be possible to solve this and be able to automate this process. I'm just having trouble with the "scripting" format and can't find documentation of this specific feature of FFDshow tryouts Input files are AVIsynth scripts with DirectshowSource("filename") command only I also tried feeding all the avs scripts to a Mpeg 2 encoder but it crashes so that's why I'm trying to use VD. Help is appreciated. Thanks
