In this tutorial, Andrew Devis shows one approach to matching footage from different cameras. Sometimes, as editors, we receive footage from our clients that is from different cameras which may not have been set up in the same way.
This can lead to a jarring effect when viewing the footage back as you switch between cameras which can distract your audience - a very big foe-par! But, matching cameras can be a difficult and frustrating process.
While the solution Andrew demonstrates isn't instantaneous and will require time to master, once mastered, it will enable you to quickly and effectively solve problems to (at the very least) ensure your audience isn't distracted when you switch cameras.
