AVI Walkthrough Problems

[jamesd10181097]

I am having trouble with exporting to AVI. Earlier this week I exported one and it worked fine I had used the Cine-pack codex. However the compression was set too high and the speed of the camera in an area was to fast. So I adjusted the camera speed to the way I wanted it and exported a hidden line AVI to make sure. However now if I try to render the export Revit crashes, let me rephrase that, it freezes and does not respond. It will not even close when I ctrl-alt-del and end task in the task manager. So I have to restart the computer. I have been trying it for over a week, getting very frustrated and now I need this done for a presentation in a couple of days.

I've had problems w/ cinepack codec too. Try exporting uncompressed and add compression in post w/ Premier or MovieMaker or something after you get what you want out.

Be aware that uncompressed files will be very large.

1. You write "render". There are some bugs in the current rendering functions. If you test it with just a shaded view, you'll see if you can blame the codex or not.

2. AVIs have a maximum size - 2 or 4 Gb or something, thus a long animation will have to be cut up into different parts. I've found it to be around 500 frames at 1.5 times DVD resolution.

3. If you go into Windows' Task Manager > Processes, you can kill Revit there from a rendering "hang" without rebooting.

I have tested the codec issue by exporting a hidden line or shaded AVI. But everytime raytrace it locks up even if I reduce the resolution to 100x75 and only render 5 frames.

I don't know what actually is causing these current rendering bugs, but try rendering it on another, different-hardware computer.

I recently was able to render something on a humbler computer that wouldn't go on a rather mighty one.

PS: Most renderings actually work. There's just something wrong between some projects & the renderer in Revit lately.

I have been running into the same problem no matter how I export to AVI. When I use different codecs it crashes after the first frame it also crashed after the first frame when I exported individual jpgs. I wish I could try it on another computer but right now I am in my office so do not have another computer to try it on. When I am in the home office later this week I will give it a try.

When using another computer how do you get the custom made materials to the other computer. For that matter some of my problem might be that this project I did in an older version of revit. In order to get the materials to work properly I needed to change the directory for accurender to the 7.0 directory, this might have something to do with it.

Any ideas, I would switch it to the 8.1 directory but then none of my materials work. Is there a way to get the materials to upgrade to the newest version?

Maybe someone can answer that better than me but I think you have to find your user.mlib or any other .mlibs you were using and make sure Revit can find them. You can specify additional rendering mtl dirs under Settings>Options>Rendering. If your mtls use bitmaps, I think they have to go someplace correctly, too.
