Hi folks,
Does anyone know if its possible to seperate a 3D MKV file into two seperate files? ie: left and right eyes.
I have an MKV file that I need to reverse the frames on, as they play in the wrong order....
Basically need to swap left and right.
Thanks in advance.
Try StreamFab Downloader and download from Netflix, Amazon, Youtube! Or Try DVDFab and copy Blu-rays!

The way MOST MKV 3d files are comprised are as the 2 anamorphic Side-by-side (SbS) images contained within a standard 2d video frame.
The way to separate them is to:
1. Crop in 1/2 horizontally (1st keeping the lefthand side)
2. Resize the remaining piece 2x horizontally, while keeping the vertical size the same
3. Export to separate file
4. Repeat steps 1-3 but keeping the righthand side
Like these 2 scripts:Code:OriginalClip = DirecshowSource() LeftHalf = Crop(OriginalClip, 0, 0, -(OriginalClip.Width/), 0) Left = LanczosResize(LeftHalf, (OriginalClip.Width), (OriginalClip.Height)) OriginalClip = DirecshowSource() RightHalf = Crop(OriginalClip, (OriginalClip.Width/), 0, 0, 0) Right = LanczosResize(RightHalf, (OriginalClip.Width), (OriginalClip.Height))
Or
You could skip that all and just watch the file un-reversed-and-exported by viewing in Stereoscopic Player and flicking the "reverse views" toggle switch. Or use AVISynth and a swapviews script*, frameserving to any player app that accepts AVS files.
Or
You could just watch the video as-is, and flick the "swap views" toggle switch that is available on (AFAIK) EVERY 3d tv. They're built with this contingency in mind.

*edit:Code:OriginalClip = DirecshowSource() LeftHalf = Crop(OriginalClip, 0, 0, -(OriginalClip.Width/), 0) RightHalf = Crop(OriginalClip, (OriginalClip.Width/), 0, 0, 0) StackHorizontal (RightHalf, LeftHalf)
