Stereoid can adjust both Interaxial and Convergence in your stereo clip. By generating a disparity map of the left and right views, Stereoid lets you adjust depth long after the shoot is finished.
The left and right views rarely match straight out of the camera. Stereoid automatically corrects color mismatches. If you color grade, you'll want both views to match first. Matching by hand is a time-consuming process.
Like color matching, the left and right views often need to be aligned. Even the best rigs can be mis-aligned. Stereoid automatically fixes the alignment. You can manually tweak to fine-tune alignment.
