Last night there was a network problem in my office. I had 7 computers still rendering walkthrough portions and they all recieved the error "could not connect to stream" or something. The .avi files are there and large (70-90mb) but no video player or repair program (I tried three players and 4 repair programs) could do anything with the file. Any thoughts?

 

next time I will have revit export the walkthroughs as .jpg files and stitch them together.

Don't think you'll get anything out of those files. It didn't complate. I have split up portions of a walkthru successfully. You need lots of RAM.

 

How many seconds is each portion ? I'd say 10-15 seconds max. More than that you are pushing it. Then you are into 3D Studio Max territory.

 

Also right before you start the AVI export do a cold boot and don't start anything up except REVIT. It's all about RAM.

 

You may also want to invest in Autodesk 360. It can probably pop this out in no time. Exporting rendered walkthru's from a regular PC workstation is painstakingly time consuming. In the end the time you spend will cost you more than the 360 service would have.

 Even with the recent switch to cloud credits 360 does not support walkthroughs. My firm has 1300 credits to burn before July, so believe me, we would have used them if possible. 

 

I am creating professional grade animations, so I do it on High and 1280x720. Each computer is doing about 1 sec. I monitor the ram usage and these 12gig machines handle it well. 

 

Thank you anyway... I just wish I could get those rendered frames out of the failed files. Revit needs to compile them in real time to prevent loss.

Oooooo 1280x720, ya that's huge. I see why you're only doing a few frames each.

 

Wasn't aware of the rendered walkthru restriction at autodesk 360. So maybe upload a whole bunch of still frames for rendering and then piece them together. At least they can render them fast ?

For you or anyone else who wants to know, that will not work. I did a test and created 100 camera views in a walkthrough path. it was jumpy, rigid, and near impossible to edit. Even back when the cloud was free for subscribers it was a waste of time. and no, a walkthrough cannot be exported or converted in any way into 3d views.
