How To Make Quickmotion Pictures.

Recommended Posts

You'll need a webcam (or a camera with webcam feature) and the free program virtualdub ( ) in order to complete this little guide.VirtualDub needs no installation, you can simply copy every file to a folder like c:\program files\VirtualDub\. Start virtualdub by double-clicking on “VirtualDub.exe”. (best is to connect you webcam before we continue)Next, go to the capture mode via File>Capture AVI.If everything goes right, virual dub shows you what your camera is capturing, if not, you might have to select your webcam in de “Device” menu.Now we have to set the settings.Press 'C' or open the 'compression' dialog via Video>Compression. Here you have to select the right codec. Best is to use DivX or XviD at a bitrate of 256Kbs (you can set this by selecting one of those 2 codecs if available and clicking on the 'configure button').If you want to capture a dark scene (evening, morning, night, ...) you might enable noise reduction in order to get better results. You can enable noise reduction in the 'Video' menu,Since we don't need audio (audio won't run synchronised after speeding up the video) we disable the audio in the 'audio' menu. Simply untick 'enable audio capture' by clicking on this text. This will also reduce size a lot.Next we have to reduce the frame rate at wich virtual dub captures the movie. Press F9 to open the 'settings' dialog. If you want to speed it up twice, you have to choose 15-20fps in order to get a smooth movie. The more you speed up, the less frames you need, but I suggest a minimum of 1-2fps.Last thing we have to do is setting the capture file. Press F2 to open this dialog and choose a name and location where you want to save this file.Now you can start capturing by presing F5 or F6 and you can stop it by pressing Esc. Remember that speeding up a movie means decreasing the length of the movie, so capture during a long time.Now the speeding up. After capturing, get back to virtual dub via File>Exit Capture Mode. Now open the movie you just captured (drag and drop works). Press ctrl-r to open the 'video frame rate control' dialog. Select the 'change to' dot and enter the desired frame rate (if you double the frame rate, the movie will play twice as fast and the length will be half of the original time).In the examples, I've choosen frame rates greater than 30. Since this is too much, I let virtual dub convert the frame rate to 30.You can preview the movie by pressing the ' |>O ' button.Next, you'll need to select the compression, press ctrl-p to open this dialog and select a good codec.Since we don't have audio, we can save some space by choosing 'no audio' in the 'audio' menu.Now save the new movie file by pressing F7 and choosing a new name and/or location.
