Instead of rendering the flythrough as a mp4 (or similar) opt for rendering the individual frames as images. You can set which frames to render and break things up. For example: render frames 1-50, 51-100, etc
You can create a video again from the seperate frames in something like Adobe Premiere.
You can also present a flythrough using BIMx, which doesn't require any rendering.
Are they re-using old posted questions?
But lately they seem to be legitimate original questions that seem to make sense (not like some bot posts).
However they add a web link in their signature, or sometimes they come back and edit and add a link later.
Or if the first post is successful, they will come back and make more posts with links.
I am now wary of any new user with a user name in the format name_name_number.
Like ... joebloggs23 ... for example.
