I am using Abode Premiere Pro.
I am working on a video which has a static background. The background is almost unicolor with a light color gradient. Please see here:
I want to export the video. The problem is that in the rendered video the background gradient is not smooth. The background shows "steps" in the color gradient. This is specially visible during fade in from a black screen/ fade out to a black screen.
The "step effect" is stronger when I use a low quality or low bitrate output fromat. But even when I use very high quality output format the problem is still visible. And with very high quality I get a filesize of 13 gigabytes for a 15 minute video.
Here are some example settings wich gives a filesize of 1.5 GB. The "step effect" is quite visible.
- length: 15 minutes
- 25 fps
- render at maximum depth
- bitrate encoding: VBR, 2 pass
- target bitrate: 15 Mbps
- maximum bitrate: 17 Mbps
- Use maximum render quqlity
- resulting file size: 1562 MB
How to solve this problem? How do I get a smooth output and acceptable file sizes? What is the best format, the best codec for this?
