We're sorry about the poor experience. Please try to switch from Hardware Encoding to Software Encoding (under Export Settings > Video tab > Encoding Settings > Performance) & check if it's exporting properly. If you are still experiencing the issue try switching the Renderer to Mercury Playback Engine Software Only & check if it works.
Hope it helps.
Hi Sumeet, I tried changing to Software Encoding and also changed the render to Mercury Playback Engine Software only. It still fails. 😞 Any other suggestions?
