I knew basically what these were about:
- Max bid depth to make use of all the information in a more-than-8-bit video file, such as a 10-bit recording.
- Max render quality to employ higher-quality but slower scaling algorithms – only relevant when scaling of course.
However, there are options to set them in the Sequence and also in the Render. Like others, I wanted to know firmly (not just by guesswork) how/when to use these.
The answers appear to be:
- Their values in the Sequence settings only affect the preview, not the render.
- Their values in the Render dialog override their values in the Sequence.
Hence:
- In the Sequence, one would tend to leave them disabled, other than temporarily for quality check or comparison.
- In Render dialog, one might tend to have them initially disabled, for render-speed, then enable them later on for final quality-check and production.
