Might be splitting hairs, but since this comes up every now and then, I think it's worth noting that there are some important caveats to using the local_matrix knob to do that for animated cameras:
- You lose the ability to tweak the animation afterwards. - Inaccurate motionblur. If you bake animated transform knobs into a single animated matrix, you're effectively losing the ability to interpolate "curved" paths correctly. The matrix values will interpolate between frames, but there's no guarantee that the result of that interpolation will match the transformation you'd get by interpolating the original rotation/translation/scale values. Getting back to the use case of the original post, I would recommend keeping the two separate transforms when exporting out to Maya. For one, if you use the "forced local matrix" approach you'll have no easy way to transfer that to Maya (as in, it won't export correctly when writing an FBX file, for example). But also, if you're planning to refine animation later on, it might be easier to do so on the original transformations.
