Cutting videos is very easy thanks to the VirtualDub tool.
Once we have launched VirtualDub, we just have to go to File / Open video file. VirtualDub supports the vast majority of video formats (except for high definition and mpeg2 standard).
We locate the video through the small browser that launches us, we select it, press the Open button and it will load the selected video.
With the video already loaded, we will use the lower panel to move through the video and locate the piece that we want to extract.
We have a scroll bar and fast forward, as well as a frame counter. At this point you have to use these two buttons: what to explain:
- The first serves to indicate to VirtualDub the beginning of the selected segment.
- The second is used to indicate to VirtualDub the end of the selected segment.
To simplify our process we will extract the first minute of the video that we initially loaded, using the indicated keys.
In this case, we will only need to position ourselves at minute 1, which coincides with frame 1500 in this video, and press the button and VirtualDub will automatically mark the start and end of the segment that we want to extract in blue, as you can see in the figure.
Once the piece has been selected, we only have to tell the program what conversion we want to give to the selected piece and save it.
Since it is an extraction, it is not necessary to process and render it, so in the Video menu and in the Audio menu, the Direct Stream Copy option must be selected.
Finally, to save the selected piece, you have to go to the File / Save Segmented AVI menu, set a name and save it, for which it will not use much time by not rendering and simply copying.
The quality of the resulting video will be the same as that of the original video, both in video and audio, when using the Direct Stream Copy option.
