| Hi everyone! I am looking for a filter, wich drops frames by differences between them. So i want to cut out the still frames, wich not contains motion to previous one. I want to keep only the motion in a video. I think it shoud be a filter to do that, but I just can't find it. P.S. I am sorry about my bad language usage, but I am hungarian. So please help! Thanks. |

| You do not tell how long the video is and how strong the motion between frames. What you could do is make use of a parameter that is present in compression codecs like DivX, namely "Max. key interval". You can set it to a large number of frames (> 250 frames). When you compress your video file, only key frames will be inserted when there is great difference between one frame and the next one. Afterwards you could load the compressed video file in VirtualDub and only keep the key frames (indicated with "K"), but you will have to do this manually. Maybe it is an idea that can help ? |
