Whenever I try to record at this resolution, my output appears to be split into 12 small videos in a grid pattern, black and white low quality, instead of the three side by side videos I get at 320. If I turn off Raw, it does take three side by side at 640 but there are a lot of frame drops and its basicly not usable. I can't find anything in the forums regarding an issue like this is it a codec seting on my machine?

In raw mode video is written in special format: each camera is presented by 4 gray-scale frames in one column, each of which is half size of selected resolution (320x240 for 640x420 res. and 160x120 for 320x240 res.). It because of in raw mode data from cameras received in Bayer pattern and iPiRecorder don't restore original picture itself (CPU is a critical element during video recording).

Try to open this video in iPiStudio - it should be look fine.

you are correct, it does, thank you so much
