1.3. Post Processing

After the video has been recorded the video and audio tracks are synchronized in a program like Adobe Premiere. Add overlays like copyright information etc.

Editing the video together afterward doesn't have to take so much time if you did the recordings well without too many mistakes and with good means to synchronize video and audio.

One significant thing to do is to get the uncompressed video compressed as QuickTime/Animation which is a lossless compression that will reduce the size to a few percent of the uncompressed version. (edit, by Michael Perkhfoer: This step is not necessary any more, if you do not use Corel Capture)

This is the steps to take in Adobe Premiere:

  • Synchronize audio/video in Premiere and play the whole thing. Cut away times with silence/waiting. Trim ends of each clip.

  • Divide into smaller sections if needed with 2 seconds black in the end.

  • If you have mouse clicks in a separate track you might export Audio separately. Otherwise just include the "original" audio-track.

The result is now a set of edited and compressed clips and audio tracks. These are considered the "originals" for archival purposes.

OVERLAYS

Adobe Premiere

Before we export the videos to the final format for download we might want to add some overlay graphics:

  • A copyright notice.

  • "Admin Login" sign if you are switching between a backend with a regular user login and an admin-login backend.

  • "Method #1", "Method #2" signs if you are demonstrating multiple ways to do something.

The Premiere project we have now is the original production which should be backed up for editing later if anything is needed.

Photoshop files for this can be downloaded here.

In Premiere these kinds of overlays could look like this on the time line:

Each clip must have the Transparency setting set like this:
