video cut and combine

[hito88]

How to cut and combine an .avi file......? Let say a video file containing frame 0 to 100, frame 40 to 60 are unnecessary.

I don't think this is possible. The only way I know to do it is to read the images from one AVI file and write the ones you want to a new AVI file.

AVI File format is a container file format. You can have different encoded content in it. You need an appropriate codec to decode the content. If the content is compressed it is in principle done in the following way

- Save a full image

- Save changes to the full image several times

- start from beginning

 As human eye is more sensitive to intensity changes than to color changes the color information needs lower frame rate than the intensity information.

Thus the codecs are rather complicated and you cannot cut the AVI file at any position without decompressing it.

E. g. virtual dub can "Remove segments of a video clip and save the rest, without recompressing." I think it can be controlled by a command line interface.

I found a simple way to do it by using in range and coerce function (input for frame number that i want), IMAQ AVI write frame and case structure. If the frame is equal to the input, then it will save that particular frame. Thx for the help.
