GoPs start with an I-frame, that contains a whole and complete image, and then it's followed by P- and B-frames that describe what has changed since the last frame. Interframe compression formats like H.264 compress video not as frames, but as groups of frames, called a Group of Pictures. (No plug intended).Ĭheck out their website and see if they have a version for your operating system."īasically what /u/rustedsanity said. It warns you if your cutting in the wrong area. I dont know what os you use, I run linux, and there is a program called Avidemux that will keep you from making orphan b frames. If the i's are messed up, the audio goes south till they match up again. If b's are missing or damaged by the trimming process, the vid will freeze or stutter utill their in sync again. The two work together to render out a complete stream. Ok, vid streams are made up of b frames and i frames. These 2 comments in particular struck me as being important. I am recording with my phone and the VDSC screen capture tool. (I am working on reaction videos.) It is the video that is not being cut that is freezing for a quarter of a second.
(Sometimes it does not freeze so some cut points are fine others freeze) The freeze seems to as far as I can tell only affect one of the two videos. When I use the spilt into parts tool there is a brief little freeze at the point of the cut.
