Export two perspectives in parallel (without time shift) / alternative to 360° videos

For an exhibition we would like to project our Twinmotion project (as exported video) on two screens. The two screens are at a 90° angle to each other.

So far, we have achieved the best result by exporting a 360° video, which we then edited with the help of After Effects (composing, post-processing and re-exporting the two perspectives for the two screens). The big downside: exporting 360° videos (8k and only in 25fps) takes forever! Currently 1 hour for 2 seconds of 360° video.

It would be great to simply solve the two needed perspectives via 2x separate (normal) video exports (0° + 90°). However, there is a big problem with this approach: moving elements like water and birds don't run in sync and the exposure (auto exposure is off) also changes depending on the perspective. This means we can't simply stitch the two separate videos together, because it clearly doesn't fit together visually in the transition area.

Since we only have a GTX 1080 Ti, we might try cloud rendering services like iRender in the short term. Has anyone had any good experiences with this?

Or are there other solutions to our problem?

Thanks in advance.

A short update about our first experiences with iRender (cloud-based GPU server rendering):

  • fast account setup
  • good documentation about how to use
  • acceleration of the required render time by a factor of 4 (before: GeForce GTX 1080 Ti/ iRender: GeForce RTX 4090)
