Half SBS Video with FFmpeg

[PsyDonias]

is that possible. I have read that something like this should work can anyone help me with this.


ffmpeg -i input.mkv -vf "[in] scale=960:1080, pad=2*960:1080 [left]; movie=right.mkv, scale=960:1080 [right]; [left][right] overlay=1920:0 [out]" -b:v 10000k -vcodec libx264 -an SBS.mkv

Not familiar enough with ffmpeg's order of operations, but it looks like it should work. Strange that your left image would be called "input" and your right, "right" (but that's just me). But shouldn't the "overlay=960:0" ? Right image starts at midpoint, correct?

This assumes you have 2 completely separate standard 1080p 2D files, one for each eyeview.
I'd suggest using the more generic height & width features, or calculations, to make the same script easier to use with various dimensions of video...

I understand you have two video files (left and right), so try that:

ffmpeg -i "left.mkv" -i "right.mkv" -filter_complex "pad=in_w*2:in_h, overlay=main_w/2:0, scale=in_w/2:in_h, scale=-1:1080" -b:v 10000k -vcodec libx264 -an "output.mkv"

that seems to look more good will try that one.
Yes I have the lefteye file and righteye file. I have several Blueray disc that I want to do an backup off and it should be playable in my Media player.

Actually you can remove this part "scale=-1:1080" if your input streams are already 1080 pix in height.. I put this filter to reduce the output for my phone (EVO 3D) by using "scale=-1:540" instead. The "-1" automatically calculate the width and keep the aspect ratio of the video.

Good luck with ffmpeg, it's a powerful tool when you know how to use it!
