While rendering with temporal samples >1 metadata for camera in exrs are incorrect.

Steps to Reproduce

  1. Create a sequence with one camera that is 100 long and has frame rate 24.
  2. Add a key for location on X at frame 0 and set it to 0. Add second key at frame 100 and set it to 100. Make both keys linear. Now on every frame the position on X will increase by 1.
  3. Render sequence to exrs with temporal samples 1. Then metadata in exrs are correct for example 1st frame has metadata for variable on path unreal/camera/curPos/x 0.0 and second has 1.0.
  4. Make exact same render but with temporal samples 4. Then 1st frame has value for unreal/camera/curPos/x 0.1875 and 2nd has 1.1875.

This behavior is causing serious issues further in the pipeline for example in Nuke because by changing only the temporal all frames then have different transforms. And not only transforms are different but focal lens and other properties are wrong as well.
