Now, the frame I selected is the first frame. I navigate to an I-frame, select everything before it, and delete it. To create a short clip, I segment what I want from the video.

Here I advance one frame, and see that it is a P-frame. If you have a video that is all I-frames, this tutorial can’t work unless frames are converted (uploading it online, then ripping it off can help). You may even have a video that starts with an I-frame, and the rest are all P-frames. Other times, you may find an I-frame in regular intervals of some number. Sometimes, you will find an I-frame for each camera change in a video.

I-frames (or “key frames”) come once in a while to establish an image on the screen, and between that and the next I-frame are some number of P-frames that are simply motion and color information for the pixels. There are usually more P-frames than I-frames. There are other types of frames, but the most common kinds are I-frames (intra-coded frames) and P-frames (predicted frames). Now I see the video is loaded! I’m on the first frame of the video, and I can see that it is an I-frame. You can use the buttons to navigate throughout the video. On the menu regarding the mode change that pops up, I just say no. The program I’m using to watch the video is VLC media player.įor this example, I downloaded a movie clip from YouTube, and dragged it into Avidemux.

There are several techniques you can try, but this tutorial will focus on what is sometimes called the “blooming” effect (repeating one P-frame over and over). The program I’m using to corrupt the videos is called Avidemux, and I’m using version 2.5, because it has the ability to copy and paste video frames. Hey, everyone! I wanted to share with those interested how I create datamosh videos and with Avidemux.
