I have now uploaded Full SBS and Half SBS examples of the Avatar 2 trailer, converted to 3D by Stream to 3D, in .mp4 (H264) format. These can be found at the page below:
Half SBS Format with 16:9 Aspect Ratio correction in .mp4 format (suitable for BigScreen Standalone playback - uses the Stream to 3D BigScreen presets):
These have the default frame stretch factor of 8%. The 3D effect can be heightened or reduced in Stream to 3D by varying this factor, it is a personal choice.
