Introduction

Appending


Let’s do what we just did again, but this time in a different manner. As before, we want to have the range 200-500 but also save it as an independent video; let’s also assume that the video is uncompressed or compressed losslessly so that we don’t have to worry about cutting on a key frame. We can of course delete the [start, 199] and [501, end] ranges but that would be superfluous, since VirtualDub provides this for us. Select the range; if you don’t remember how, flip back a couple of pages. Select Video | Direct Stream Copy and finally click on File | Save as AVI or press F7. Define a filename and click Save.

Now we possess a video with just the scene we are interested in so we will append it to the end of the original video to achieve the same effect as before. Click on File | Append AVI Segment and select the file you just saved. VirtualDub will add it to the end of the video or pop up a verbose error message similar to the following image if the videos are incompatible:
