How to Batch Convert Old Blue Iris BVR Files to MP4
In this HowTo we’re going to demonstrate how to batch-convert Blue Iris BVR files into MP4. The situation we’ll look at today is one in which you have old BVR files that cannot be placed into your existing production, because Blue Iris has settings that control how old clip files are managed.
You can download Blue Iris without activating it. The trial will operate for 15 days, which should provide enough time to do your conversions. A virtual machine is an ideal environment for this task.

Your BVR files
Take note of the number of BVR files and the amount of disk space they require.
Configure Blue Iris
Launch Blue Iris, go into Settings, and select the Storage tab. Blue Iris has a number of default folders. This how-to will use the Stored folder.
- Take note of the location associated with this folder (default: C:).
- Adjust the size of the storage location so it is larger than the total size of your BVR clips.
- Uncheck the Limit clip age checkbox to ensure Blue Iris does not delete them.
Finally, shut down Blue Iris.
Next, transfer your files to the Blue Iris folder. Once the copy process finishes, relaunch Blue Iris. It will automatically index the clips.
When indexing completes, compare the number of files and their total size with the originals.
Converting files
To batch-convert the files, select them, then right-click and choose Convert/export. You may uncheck the Re-encode video option if you don’t need any of the additional features under that option—unchecking it speeds up the process.
You will be asked to select the location where you want the converted files to be placed. The conversion progress is displayed in the Database dialog box.
Blue Iris before 5.9.9.91
Versions of Blue Iris up to 5.9.9.90 had a bug: while the files are indexed, they never appear in the Clips section.
A workaround that triggers the footage list is to add a camera. There is no need to fully define it.
