I have an important video file taken on a Sony Handycam HDR-cx300 that has a valid filename and reads the correct file size. It plays back fine on the camera, but I'm not able to use the file as is written to the memory chip. I can't open it with any of my video software, nor can I convert it to another format. Adobe Media Converter reported the file as "corrupted." Since it will still play back on the camera, is there a way to access the data?
