I uploaded this file and it would be nice if someone could tell me why the inside walkthrough (called video) won't even start or export anything...

The file used to be good and I made several videos already but after the last changes in the file the video has become impossible..

Anyone whith an advice ? Would be nice because I promised this video before wednesday to someone...

" but after the last changes in the file the video has become impossible..". What were your latest changes?. But in anyway, you have a lot of 3Dtrees in your scene and the shadows are on, so I think, it could be slowing down the walkthrough.

I don't know exactly with which changes things went wrong... At a certain moment I splitted the project file in one with only a walkthrough in it with a reference (link) to the major building file and one with the project itself. In that way I could work on renderings in the major file and make videos through the smaller file with only a walkthrough. Things got slower when I put some cars in the scenery. From then I  copied the walkthrough back in the major file and gave it the name video. The trees were not the problem. But I don't think either that the cars are a problem. The video is slow from the first pictures when there's no car in sight.

Just explanation why splitting the files up in first place: In that way I can make renderings and walkthroughs on seperate computers in the same time.

The strange thing is that calculating the video goes very slow but the Revit program uses only one off the 7 processors. I mean it's an i7 processor but only one off them does the work. In making renderings all 7 processors work at the same time at maximum speed.

Calculating the 4 min. video takes about 20 hours in this way...
