Once you are done deleting I-Frames, save the file using the Save icon or File->Save. You may get the following error when you delete the I-Frame. You can now delete the frame by pressing the delete key or select Edit -> Delete. Next, advance the play head one frame and click Set End Marker (it looks like a B in a white box). To delete the I-Frame, first click Set Start Marker (it looks like an A in a red box). Use the arrow keys to advance the play head till you find an I-FRM in the Frame Type indicator near the bottom of the window.

They will usually be near a section where there is a jump to the next scene or a lot of motion. We need to leave this one or the video will not play at all, but we still need to find and remove the other I-Frames. There will be one I-Frame at the beginning. We will need to remove these so that the decoding errors will occur.Ĭlose Avidemux, and then reopen Avidemux and open the file you just created by clicking on the Folder Icon or selecting File -> Open. Avidemux will still insert a few I-Frames.
