Exporting a Walkthrough or Solar Study in Revit Results in a Blank .avi File

Exporting a Walkthrough or Solar Study in Revit Results in a Blank .avi File

Issue:

When exporting a walkthrough from Revit, the video compression dialog does not appear. As a result, an empty .avi file with a size of 0 MB is generated, and the file cannot be opened.

Causes:

This issue can occur due to several reasons:

• No video codec is installed on the system. Revit skips the codec selection step during export if none are found.
• The Logitech webcam software installed on the system has expired.
• Conflicts arise from certain installed codecs interfering with the codec Revit requires for exporting video files.

Solutions:

Try the following steps to resolve the problem:

• Verify if the system has video codecs installed. If not, install an appropriate codec package.
• Note: For guidance, see: How to Identify Installed Codecs on Your PC
• Update the Logitech webcam software to the latest version.
• If updating is not possible, try manually disabling the Logitech module by renaming the file C:WINDOWSSYSTEM32lvcod64.dll to C:WINDOWSSYSTEM32_lvcod64.dll.
• Download InstalledCodec.exe from Nirsoft. Use it to disable all unused codecs, then enable the following codecs:

• Microsoft Video 1 Compressor
• Microsoft UYVY Video Decompressor
