Not sure what you are saying here?

Yes, ImageWriter() does not throw a compile time exception if future frame writes are going to fail. DEViL errors during frame writes are text overlayed on the output frames. This is by design.

No, ImageWriter() in EBMP mode only checks for file creation errors, subsequent errors (like disk full) on the writes and close are ignored, a future version may change this behaviour.

We currently have no plans to throw runtime exceptions from ImageWriter().
