hello
It is perfectly possible to ride in 3D from Pinnacle Studio 17 (first update in 17.6)
1) Place the left clip on the track # 1
2) placing the clip on the right track # 2
Open "effects" - "stereoscopy"
Assign each clip effect "left eye knob" for track 1
Assign each clip effect "selector right eye" for track 2
And by selecting "anaglyph" on the timeline you should see the clips in 3D with red cyan glasses.
Made installation and make either side by side or 50% multistream
I am at your disposal for further information
I'm french and I'm using google to translate, please kindly escuser me
