need help with incomplete video capture

[Twistid]

hey, i have a video only movie (no sound) but i cant watch it becouse my video-wizz friend told me that theres no header, he said its an incomplete video capture and i need someone to piece together a header or get the video data out of it or something like that

heres what happend, i was recording a video from a camera hooked up through a USB port it was live, and windows went gay on me and shut down the program becouse i was running out of ram (to many programs) it saved everything it had recorded up to the point of cut-off i just need someone to fix it for me , please if you can help me aim me at icptwiztidfreek or just reply here

btw the video is 130 some megs, i can get on irc and ftcc it , or send it through aim or some other way if you want, and if you also need i can record another video the same way if that helps

thanks alot :cool:

It is AVI format right?

Have you tried opening it in VirtualDub?

[killingspree]

as awatef said, try to open it in virtualdub(mod). if this works ok, first try to do a directstreamcopy of the movie (which would reconstruct the header). if that doesn't work out the way you want it (searching might be awefully slow afterwards) you would have to do a recompress. (which you might want to do anyway)

virtual dub dosent know what kind of file it is. it ends with .avi but it dosent have the header and whatnot that tells it what kinda video/decompresser it is (i assume, i know very little about videos)

[Twistid]

what is that recompress thing? i cant re-record the video if thats what you mean, i need to salvage this video it has "important" stuff on it

[Twistid]

anyone else wanna try and help out ???:confused: i'd really appreciate it :D

Try to record a small video with same settings, concatenate both to a bigger one and open the new avi in vdubmod.

[Twistid]

i opend vdubmod, opend another video i captured with same settings , then went to file append segment and chose the other video and it said "invalid avi file: not a RIFF file"

any more idea???? please keep em comming!

[oddyseus]

I wasn't reffering to vdub for this. It obviously can't join two files when it can't able to recognise one of them.

I am not dealing with avi files at all so I can't reccomend any avi joiners, but there is a bunch of them out there. There is even a dos file command that concatenates a number of files together, but currently its name eludes my mind. Perform a search on avi joiners or join two files or on a similar argument.

I do believe that u can work things out in u can join a valid file with the faulty one.

Perhaps a Graphedit approach is a good one too.

The same filters that can open your valid file can be used to dump the contents of the other one in a new avi.

[Twistid]

odysseus , could you tell me how to do the graphedit thing? i downloaded graph edit + loaded up the valid .avi , but i cant figure out how to do it from there (sorry im a newbie)

[oddyseus]

if u can playback the valid avi, let the filters as r and load in source the faulty one, at dest choose the dump filter. U will be asked to name the destination file, then hit play. U will end up with a dump of the avi file that should be editable from vdub.

[Twistid]

i loaded up the valid file, but i cant figure out how to load up the faulty one as source, i dont see any option or button for it, and i cant figure how to dump them (sorry if im startin to get annoying , but this is really important)

[oddyseus]

from file/render media file and choose the new avi. It will build a graph to display it.

Rebuild the graph by changing the input file (put the faulty one there) and the renderer to the end, as u don't need to see the video just to copy it, with the dump filter. It will ask u a file name. Give it one and hit play.

i did this...

how do i change the input file??? and which is the input file, the very first box that has the filename of the movie "movie2.avi" ???

[oddyseus]

Insert the filter, I think that it must have used the Asynchronous one and link appropriately to the rest of the graph.

there is no "Asynchronous" under the filter list :(

[oddyseus]

it was a kind of fuzzy statement, I must admit.

the filter is called File Source (Async) and it is located under the Directshow filters.

sorry about that. :)

ok, i load up the valid avi (movie2.avi) , then i load up the file source (async) filter, and load up the faulty avi (movie.avi) , i delete the box "movie2.avi" and try to connect "movie.avi" where the faulty one was but i get this error

"These filters cannot agree on a connection. Verify type compatibility of input pin and output pin. "

:( mayby im doing the wrong thing, you said to change the input file but the movie is an "output" file... or mayby im doing it totally wrong?
(i also tryed to connect the faulty movie with all the other boxes, none of them work)
