Decided to determine some specs on the CGO3+ camera and learned a few things. First, regardless of the format of the SD card (FAT32 or ExFAT), the videos are broken down into segments of 1.89 GB, meaning you don't gain anything by formatting at ExFAT other then the fact that ExFAT SD cards are not recognized by the current version of Android (KitKat 1.4.4) in the ST16. I've attached a pdf version of a spreadsheet showing the file sizes and MB/min for the various resolutions (I recorded approximately 1 min at each and normalized to exactly 1 min). This should give folks an idea of what can fit on various sized SD cards. For the photo buffs, JPGs are 2.6 MB each and DNGs 24 MB (no surprise there). Two things of concern (at least for me) [Yuneec, are you listening?] The ST16 was pretting good at starting the video with a single push of the video button. However, in most cases, it took multiple presses (max 4) to stop the video. It's as if the ST16 isn't polling the button fast enough to be responsive or the camera is busy buffering to the SD card and isn't paying attention, but not sure. When I changed camera resolutions, all of the various options appeared (on the ST16) as having the same picture brightness. However (and I tried this several times), when I selected the 1920x1080F120, the picture was significantly darker. Maybe Yuneec can explain why this is.
