The way many codecs work is they take a full frame as a kind of "master" (Keyframe) and for subsequent frames, it calculates changes to the Keyframe and stores the differences. Why does everything I find suggest that reverse frame-by-frame is basically impossible except for resource-hungry professional video editors like Premiere, and yet here I am using this exact feature with PotPlayer for years now without issue even on an old laptop?įrom what I understand it is literally impossible, but is easily "faked". This has got me really curious as to what's going on here. I just hit the "previous frame" key and everything works as one would expect it to. Not even on my old laptop (at least nothing beyond the normal sort of performance issues that basically everything suffers from on an ancient laptop). I've just tried again with a couple dozen videos of varying types (3gp, avi, flv, mkv, mov, mp4, mpeg, webm, wmv) and not a single one has had an issue. No major performance issues, no massive resource usage, nothing. I've been using this exact feature in PotPlayer without issue for a long time now, even on my old (mid-2006-2008, can't remember exactly) laptop that I still use on occasion. It simply is not feasible within bound and reasonable computational, memory and bandwidth limits because video codecs and container formats are not meant to be played in reverse." To quote Rémi Denis-Courmont from the second link: "Reverse frame-by-frame is impossible. Videos keep crashing on windows 8.So VLC doesn't support going backwards frame-by-frame, and everything I've found about this says that there's no possible way it even could support this, at least not without a whole lot of work, and the end result would mean a huge increase in resource usage as well as large decreases in performance.Ī couple of examples of what I find when I search about this: Problems with video files and editing softwares HD Video Being Compressed & Causing Artifacts Videos keep crashing on windows 8.1 and even after clean install of windows 10 Unable to play videos (VLC, YouTube, MPC-HC etc.)Īll Media Players Crash When Playing Any Video Files?

Vegas Video Editor Finished Renders Not Playing In Any Media Player With that said, why does the video go blurry/pixelated when I'm playing a video with the VLC Media Player if I pause and move ahead one frame at a time too many times? Does anyone know how to make it so that it doesn't ever get blurry/pixelated no matter how many times you move ahead one frame at a time? Yes, the video is smaller when it's played within Camtasia and yes, Camtasia is a video editor and not a video player, but if Camtasia can avoid making a video blurry then why can't the VLC Media Player? The thing is, after pressing the “E” key to move ahead one frame at a time, the video eventually goes blurry after about a dozen or so presses of the “E” key.ĭoes anyone know why this happens and/or how to make it so that the video never goes blurry when doing this?Ĭompare this to playing a video within Camtasia which never makes a video blurry (at least as far as I've found to be the case) no matter how many times you move ahead one frame at a time. When you pause a video being played with the VLC Media Player you can move ahead one frame at a time by pressing the “E” key on your keyboard. I have a question related to the VLC Media Player.
