Which conversion program was used?

[mesaboogieman]

Hi
Just wondered if it is possible to identify which program/encoder was used to convert a DVD to avi,xvid,svcd etc from the resultant file.

I have several xvid movie files which are very good quality and would like to know what program was used to convert them from DVD.

Thanks

Well in terms of XviD whether in avi, mp4 or whatever container, I would be more interested in the build used and encoding settings. Any filters used would also be usefull, but there is no way you can tell that just from a file. The actual app used for encoding makes little difference. The colour depth should be 12 though as it means that the encoder was fed YV12 input.

For avi first thing to look at would be the compression used.

For MPEG1/2 the program used usually includes the codec so it is more important.

Also, not every software application that processes video/imaging
will write a signature - can be anything. I do know that some
MPEG encoders do this. TMPGenc for instance does.. though, some
version would write it in various locations, its a matter of
sticking to the standard, if there are any such for "signature
writing".
.
A long time ago, I was thinking of the idea of writing a tool
to read in various MPEG ( *.mpg and *.m2v ) files and read in all
signatures, but (regarding TMPGenc as an example) I found that I
was having to read through the whole file to *search* for a reference
string or something to lock onto.
.
I wrote something really dirty, to read in AVI files, to gather
*basic* information (turned out ok) but I found GSpot to already
do this, and pretty nicly, but I was just creating such a tool for
educational purposes. Anyways.

If there is a standard for signiture writing, then, I would look
into that, and then read in every file (if you have some programming
background)

Unless you want to just *know* which app encoded the given video,
be it AVI; MPEG; or whatever, and there is a standard signiture for
all these, ..then as celtic_druid mentioned above, ..is more important.
