How to convert Half SBS to Anaglyph 3D

[VHser]

What is the best and easiest way for a noob to convert half SBS to 3d anaglyph. I already converted one video on multivchd and it seems good, but is no longer being developed and the time of conversion is to long (15 min to convert a 5min 1080p mkv avc file). Maybe there are a better program/method for this. Also if the program has compatibility with CUDA for encode faster it would be good

sorry for my bad english

Do you mean for resaving or do you mean for direct viewing?

If the first, use an AVISynth script as frameserving source to an encoder.
If the second, use Stereoscopic player.

Thaks for the answer Scott. i don't know how to use AVISynth: what script should i use, how to create a script, how to use the script...?

I use TMPGenc to conver videos to mp4. it is fast because can use CUDA technology.
Can i use this encoder with the AVISynth? What encoder do you recommend to convert sbs to anaglyph?

greetings, VHser

EDIT

I already know how to use the avsynth with TMPGenc. I'ts very simple. I use the script that yoda313 here - https://forum.videohelp.com/threads/333552-What-program-to-convert-sbs-left-right-to-an...1#post20745897. Now i need to know how to convert to anaglyph red cyan insted of green magenta

I already solve my problem. now i know how to convert half sbs to red cyan anaglyph

the yoda313 script is this (magenta green anaglyph)

#ASYNTHER DirectShowSource
DirectShowSource("E:\****3D.Title1000.mkv")
ConvertToRGB()

# extract left and right views as separate videos
left=Crop(0,0,width/2,-0)
right=Crop(width/2,0,width/2,-0)

# merge color channels to make an anaglyph image
r=ShowRed(right)
g=ShowGreen(left)
b=ShowBlue(right)
MergeRGB(r,g,b)

LanczosResize(1280,720)

- You can change the "LanczosResize" to resolution of the source or other with the same aspect ratio

to convert to red cyan anaglyph you need to change the "merge color channels part". so if you want to convert to red cyan anaglyph use this script

#ASYNTHER DirectShowSource
DirectShowSource("E:\****3D.Title1000.mkv")
ConvertToRGB()

# extract left and right views as separate videos
left=Crop(0,0,width/2,-0)
right=Crop(width/2,0,width/2,-0)

# merge color channels to make an anaglyph image
r=ShowRed(left)
g=ShowGreen(right)
b=ShowBlue(right)
MergeRGB(r,g,b)

LanczosResize(1280,720)

- You can change the "LanczosResize" to resolution of the source or other with the same aspect ratio

If you want to convert to yellow blue anaglyph use this script

#ASYNTHER DirectShowSource
DirectShowSource("E:\****3D.Title1000.mkv")
ConvertToRGB()

# extract left and right views as separate videos
left=Crop(0,0,width/2,-0)
right=Crop(width/2,0,width/2,-0)

# merge color channels to make an anaglyph image
r=ShowRed(right)
g=ShowGreen(right)
b=ShowBlue(left)
MergeRGB(r,g,b)

LanczosResize(1280,720)

- You can change the "LanczosResize" to resolution of the source or other with the same aspect ratio

Conclusion
The time of conversion was similar (maybe because of the source file size). On TMPGenc there is no color change, in one hand is good, but in the other hand, the red based colours (LG logo for example) are "agressive" to the eyes when you put the anaglyph glasses (homemade). On AVCHD the colours change and doesnt exists red based colours "agressive", but the colour contrast is poor (all colours are, somehow, darker, less enjoyable)

How can i get something between TMPEGenc and AVCHD encondes? :P
