Best practices - rendering a sequence
of images
The expression "frames per second" is not something new to us. A movie can have
25 fps or 30 fps, as we saw in the
Playing safe with the Broadcast Safe effect
section.
A movie is made up of a sequence of frames that when played at high speed, give
the sensation of motion and instead of exporting a video or even a small clip, we
can export these frames, which when combined, create the movie.
Is there any particular reason to render all these frames? If we had the flexibility of
using individual clips, then we will find more flexibility and control by exporting the
individual frames. With colored frames, we also can export specific render passes
that can be used to tweak lighting, add color grading, and perform post-production
activities to achieve a better result. How can we export the movie in such a way?
When we click on the Save Movie button, the window that appears goes straight to the
MP4
tab, but what we need is the
Images
tab, as shown in the following screenshot:
The initial three settings are the same as we saw in the
MP4
tab, so that should be
very straightforward. However, when we move to the
Custom output
option, we
start to feel the true power of using a sequence of images.
