We all know the Lumia 920 has a beautiful camera, and when reviewing the handset we especially noted how nice the results can be when shooting 1080p video. Still, you may want to think twice about using the phone – or any Windows Phone 8 device, for that matter – to document any particularly lengthy event, as we’re learning that while the platform can record extended videos without issue, it runs into problems when trying to get those movies off the phone.
This sounds like some kind of 32-bit addressing issue, because just over the 4GB mark, things start to get wonky. Attempts to transfer videos larger than 4GB to a PC end up with the phone only actually sending whatever’s over that 4GB point to the computer. So, instead of a 6GB video, you end up with a corrupted, unwatchable 2GB file.
Chances are, this isn’t specific to videos, but given the sizes of the files needed to trigger the problem, you’re not likely to run into it elsewhere.
For the moment, there doesn’t appear to be a clean way around the problem, short of stopping your recording below that 4GB point and recording a new video for the rest.
