The final video can be delivered in various formats and resolutions suitable for different platforms and uses, such as web, TV, or mobile devices. In general, you’ll want your production created at the highest quality.
If, for some reason, you need to compress or lower the resolution of the video for certain audiences that’s entirely possible when you have a high-quality raw video. However, if you don’t produce at a high level, you won’t have the option to upconvert to higher resolutions or formats later without seeing reduced quality.
