I am looking for any SD camcorder (or standalone recorder for that matter...small) that will support a VIDEO IN signal. I cant use a hard drive based or DV based for this application. It needs to record to MP4 and use SDHC memory modules. I have researched Panasonic and Canon and all of them seem to only support video out. Size is also and issue. It will need to fit in the nose of a fighter jet and withstand 6gs during recording. Both the Canon and Panasonic models are the perfect size. Any ideas?
