Best Video Size for Recording - (Canon 6D)





I have read somewhere that you should be taking your videos at 640 x 480. Is this correct and does BYEOS automatically set this for you when you go into PLANETARY?


I shot a few videos last night and noticed that the video recording sizes came out as 1104 x 736. I checked the camera and it is set at 1920 and 30fps IPB. Should I just leave it there or change it to 640 30fps IPB.

You need to use the 5x zoom feature.  In that mode you will get a 1 to 1 pixel resolution; meaning 1 pixel on the sensor = 1 pixel on the image.


You do not need to worry about image size, the pixel resolution is what matters for best quality.

The 640x480 movie crop mode is an in-camera function that BYE cannot control, so you must unplug the camera from your computer and operate the camera by itself.  With an appropriately fast memory card you will get a faster frame rate using the in-camera movie mode, but you won't see your image on the larger computer screen or have the convenience of tethered operation.


While I think that BYE's Planetary Mode, using 5X Zoom, gives better results, you should try both techniques and see what you prefer.

There is nothing "magical" about Planetary Imaging at 640x480.


The IMPORTANT consideration is to record your Planetary Imaging at a 1:1 Pixel Ratio - one Pixel on the Sensor recording to one Pixel on the AVI file.  This does NOT happen on any of the HD Video formats - neither 1920x1080 nor 1280x720.  In these modes, the whole Sensor (all 5184x3456 or 6000x4000 per Model) is downscaled into the chosen HD Format's max 1920x1080 Pixels, reducing the original detail by a 3:1 or worse ratio. (After all, no one wants to take Home Videos with their Fancy DSLR and need to crowd the Family into the Central Third of the Frame...)

The T2i and the 60D offer a 640x480@60fps Center Crop Video Mode that produces true 1:1 recording. The T3i offers a 3:1 Crop Video Mode @30fps.  For all Canon DSLRs, Guylain uses the Canon SDK's 5x-Zoom LiveView Mode (where their engineers seem to have "cheated" by dumping true 1:1 Cropped Video simply for the ease and speed) assembling a 1:1 Video File of the resulting LiveView Frames.  This output is of slightly varying dimensions depending on the Canon DSLR Model (never actually 640x480), and delivers the REQUIRED 1:1 ratio of Sensor Pixels to Output Pixels.
