Hello,
During the last few weeks I've been fiddling with old DV footage. Windows 7 (and/or the live photo gallery ?) has a nice capturing feature that cuts what's acquired into various files that can be named using the date and time when the footage was taken. That can result in a lot of different files that refer to the same thing.
The feature that I've been missing in VirtualDub is the ability to open or append several files at once -- obviously keeping the need for them to appear to be part of the same stream (which is the case with DV). Does it make sense?
The only way I found to do this (besides doing it manually) is by writing a script or a small program that will create a jobs file which I then have to "reload" in virtualdub. I don't think there's a lot of work involved, since Virtualdub can automatically load for "linked" segments, but it would save the user a lot of time in certain situations.
One might argue that using AviSynth would fix that, but it wouldn't, since then it becomes impossible to use direct stream copy (well, it's possible, but the stream isn't compressed anymore).
In the same principle, I've got a camcorder with a hard drive that produces MOD files (mpeg2). I can easily open it in VirtualDub, but it would be nice if I could open/append several files at once too (extend the "append" feature to input plugins). Using AVISynth here works too (no need for direct stream copy there), but then memory usage goes through the roof (well, it keeps growing). For that one, there's a twist : video and audio stream usually don't have the same duration (!), so it would be great to have an equivalent to AVISynth's "trim" function, which adds or trims sound if necessary (in order to avoid de-synchronisation).
Thanks for the hard work, cheers. 
-- Edit --
I've just seen the "Open multiple files as one virtual file" option in the extended properties when I open a MOD file, but the problem is the same: I still have to add each file individually, when it would be nice to be able to select more than one at a time, and I'm not sure it copes with the difference of durations of the audio and video streams. |

Usually I use Total Commander multiple rename tool and rename all AVIs to something like: 001.avi, 002.avi, ... (using the counter feature) and then open them on virtualdub.
I don't know how it will handle different audio/video size.

Thanks for your reply,
that's what I usually do, too, but in that scenario I'd like to keep the files' name, because they contain information about the date and time the video was shot (and to me it does make sense to keep it even though this information may not remain relevant once all the files are joined, for other aspects). Any chance of having this simple-yet-convenient (to me at least) feature any time soon ?

The only reason for keeping original filenames is if you don't erase original files (keep the raw originals). You can backup them first, and then make the renaming for Vdub processing. You could keep the name of the first file with the counter after the name. What could be tricky in a multiple file drag and drop is the order in which files are appended. Windows not always use alphabeticall order but the internal order in which files are placed on directory. (ie: Winamp changes song order when you drag a full dir because of that reason). So it's not as simple as it seems. Vdub shoud presort file list...
