The LR4.1 error message fails to provide sufficient information to find a solution or a workaround. The files in question are all AVI format. The non-imported files play okay in Windows Media Player, but just a certain few are consistently failing to import. I understand that LR4 may need to be less forgiving of certain file problems in order to support its expanded video features, but, if so, it should tell us what these problems are or allow us to examine logs or provide diagnostic tests that will reveal sources of incompatibility with LR4 import operation.
Improved video capabilities in LR4 are very appealing to me....but NOT if they fail while giving error messages which are unhelpful.
