So that's how you summon ghost frames from WTV files.
you can't just hold down the left arrow key and storm through the place: you have to inch along.
skip so much as one frame too far and those ghostly glitches you've been cultivating could vanish. ghost frames disappear just as suddenly as they appear. Of course, it's one thing to see a ghost, and something else altogether to capture a ghost. You can even do something i call dancing between the keyframes, inching back and forth through a glitchy area of the file as the artifacts become increasingly pronounced: (and i love the fact that you do this by going in reverse it really makes it seem like some magic ritual.) reversing through the file seems to trick avidemux into applying these changes wrong, thus revealing glitched frames that aren't actually in the file.

to save space, MPEG files only occasionally send full frames (keyframes or i-frames) and fill the rest of the video with p- and b- frames that only describe which pixels have changed since the previous frame. What seems to be happening here is that avidemux is getting confused and applying incremental changes in the wrong direction. if your file is damaged in the "right" way (say, via WTV transcoding), then you'll start to see frames that aren't really there: just skip to the end (or any point in the middle, if you prefer), and use your left arrow key to reverse through the file. to invoke ghost frames in avidemux, scroll through a damaged video backwards. I'd been playing around with this wtv transcoding glitch for months before i saw my first ghost frame, which i discovered by accident. Occasionally you'll get weirder, unpredictable glitches like this: Do you want to index it?"Īnswering yes to this question and no to any follow-up questions results in a video that is recognizable but thoroughly mangled. WTV is proprietary (closed) format, but it's close enough to MPEG that when i try to open a WTV file in avidemux 2.5.4, it asks me "This looks like an MPEG.

the default tv capture program in windows 7 is called windows media center, which records programs in a format called WTV. my desktop computer runs windows 7 and has a video capture card for recording tv signals off a coax connection. I initially discovered ghost frames thanks to another glitchy behavior in avidemux. for os x lion/mtn lion, check these instructions for installing avidemux.

also, during the workshop, some mac users reported that they couldn't get avidemux to install. it definitely does not work in the current version, 2.6. the process is likely to work in other 2.5 and earlier versions, though i haven't tested them. Specifically, i use avidemux version 2.5.4. ( nick extracrispy tells me he can do something similar in quicktime, for example.) my process involves a bug in certain versions of avidemux, though there are likely other ways you could do something similar. for the sake of discussion, i'll also use "ghost frames" to refer to the process i use to invoke these frames. Ghost frames is a term i use to describe video frames which do not actually exist in a video file but which are sometimes revealed when using damaged data and/or glitch processes. Give it a name and let Avidemux do the job for you.This is a write-up of the ghost frames workshop i delivered at GLI.TC/H 2112 The version tried is 2.5.2 so, depending on your version/OS and GUI (GTK or QT) it might look different but the actions to take are simply the following (see screenshot):ġ) make sure to select the format of the “Video” to produce (you can’t leave just “copy”) Ģ) open the pop up window refereed to “Filters” Ĥ) select the filter “Rotate” and add it (another little window will pop up) ĥ) choose how you want to rotate the video, click “OK” and “Close” the Video Filter Manager Window Ħ) it’s time to save the file.

It’s platform independent so that it runs under Windows, Mac OS X, Linux and BSD. Today I tried Avidemux and I got surprised with the easiness of the process and the quality of the result obtained.Īvidemux is a nice open-source program designed for video editing.

It always looks nice on camera but, as soon as you watch it on the pc screen, you realize that something went wrong… :-|įortunately there is some software that can sort this problem out for us. This post is over 3 years old, so please keep in mind that some of its content might not be relevant anymore.Ī few times happened to me to record a video with my picture camera turned in portrait mode.
