C1 Mysteriously Changing File Sizes
I have 4 CR2 raw files all shot on a Canon 1DX. I import them into a fresh capture one session and do nothing to them. When I output the 4 files (with exactly the same process recipe), two of them end up being output at 5184x3456 and two of them end up being exported at 5078x3385.
If I look at the metadata tab under "Basic", all 4 show "Dimensions" of "5184x3456". But Looking at the process summary tab, next to "Size", two show 3456x5184 and two show 5078x3385.
My process recipe is set to save them as Adobe RGB/TIFF/Uncompressed/300px/in/Fixed scale/100%. I process all 4 with the same recipe at the same time. I didn't import them with any settings or anything else. They are plain CR2 files with nothing attached to them. When I check the crop tool, none of the files have any cropping applied to them. If I click the "reset crop adjustments" icon in the crop tab, nothing happens (since there is no crop applied anyway).
If I open those same 4 CR2 files in photoshop, all 4 of them open up with dimensions of 5184x3456.
I cannot for the life of me figure out why 2 of these images are being output from capture one at anything other than their native size. This is the 2nd time I've noticed this, with files from two different 1DXs.
I'm running Capture One 9.2.1 on OS X (10.10.5), Raw files are CR2s from a Canon 1DX.

Anything checked in the lens correction tab (hide distorted area)? Were they all taken with same lens and focal length? 0 -
They were all shot with the same lens and camera, but for some reason 2 of the 4 had distortion correction adjustments automatically applied. The ones that were output smaller were set to 100% distortion correction, the two that were output at their native resolution had distortion correction set to 0%.
I didn't realize that Capture One actually crops your images down when correcting distortion (PS and LR do not). Also strange that when bringing in 4 brand new CR2 raw files, some automatically have distortion correction applied and some do not.0 -
Uncheck hide distorted area.
I would also check noise reduction and put luminance to 0 and go up if necessary.
Didn't like the auto applied default settings for NR and distortion so I "zeroed them out" than put it as new default.0 -

Probably focal length related. Did you check that?
Bear in mind that lens correction implies messing with the pixels in some way. The result will likely be something that is not rectangular one way or another.
On then has to decide whether to crop the image a little (or a lot) to use existing pixels only or create some extra pixels to give people the number of pixels they expected no matter what. Perhaps using some sort of "healing" algorithm? And hoping that the quality and content are acceptable.
In some situations from some suppliers it may be that both approaches are employed.
I think C1 developers have elected to leave out that part of the frame that probably would not have existed if the lens had not needed correction.
Canon files, in my experience and comparing using the more obvious needs for adjustment presented by my S90 or G11, (not C1 supported but there are later versions that are likely close enough for comparison) tend to leave a little more distortion around the jpgs they produce in camera than C1 does with its interpretations. There's not much in it. In most cases I prefer the C1 result. Occasionally I may change it if significant subject matter is too close to the edge of a frame.
It rarely matters as I am likely to crop the file anyway and if size is critical there is always an option to expand the result in the output process.
HTH.
