"Video Hit" is any corruption in a video file that results in a shift in pixels or visual artifacts.
Video Hits impact both the Technical and Content Quality of the asset. They usually represent a render or encoding error. Additionally, member experience is adversely affected if on screen visual hits obscure the main action of a scene. Any video hits will also be recorded into any subsequent assets derived from a source containing hits.
Video is meant to simulate archival/found/consumer video footage with inherent digital anomalies for creative intent.
Digital blocks, digital line errors/dropouts or picture breakup occurs anywhere on screen.
How to Prevent:
Determine if video hit exists in the render or is an encode issue. If it exists in the render, go back to DI and re-render affected frames. Then, re-export final deliverable.
If it is encode related, simply re-export final deliverable.
