First, don’t worry about existing grain. We need clean. (Grain can be put back, enlarged grain is not pretty.)
Set rescale to (nominally) 150% or original size - This is a multi-pass method. - You may want to experiment with a short piece of the original video to save time.
Using Proteus Relative:
- If necessary, push up decompression,
- Raise Denoise until you begin to lose detail and then back off slightly.
- Big Note: You are going to be able to refine settings on each pass; it is better to keep
your initial setting a little short of perfection, the next pass will use the previous
partial enhancements as the clues for the next pass. - If restore detail begins to show ‘dittoed’ in detail, you have pushed it too far and the AI
is ‘inventing’ detail for you. (Try to avoid this, even if detail setting is not as high as
you’d like. (Backing off denoise can help, too.) - Sharpen lightly.
- Some folks like to turn dehalo to 1 or 2; I’m not certain if this really helps.
- Push Restore Detail until you begin to it see more clearly. (You may need to go back
to Denoise to get these two ‘opposites’ back into balance.) - Save the settings and try previewing them in several places in your video. After
saving any needed modifications, Export, (using a high bitrate or lossless as
possible,) titled “Pass 1 - Your Title” - Wait until finished.
Next or final pass:
- This assumes you are going to the final pass, or full resolution, - If it is still an
intermediate step, treat settings like first step above. - Load your Pass 1 video as the source.
- Using Proteus Relative:
- Set resolution to next (or final) size.
- Decompression, should be nearly unnecessary. (leave at “0”)
- Only if any residual noise: Raise Denoise until you begin to lose detail and then back off slightly.
- Crank up detail If restore detail begins to show ‘dittoed’ in detail, you have pushed it too far and the AI
is ‘inventing’ detail for you. (Try to avoid this, even if detail setting is not as high as
you’d like. (Backing off denoise can help, too.) - Some folks like to turn dehalo to 1 or 2; I’m not certain if this really helps.
- Push Restore Detail until you begin to it see more clearly. (You may need to go back
to Denoise to get these two ‘opposites’ back into balance.) - Sharpen more, but don’t overdo. - The output can be so sharp, it seems to cut your
eyes. - Save the settings and try previewing them in several places in your video. After
saving any needed modifications, (including putting back grain, if you like that,)
Export as “Pass 2 (or Final) - Your Title” - Wait until finished.
Your final output should be superior to the results obtained going from 100% - to Full Resolution in one swell foop. (Note: Sometimes multi-pass is not necessary, depending on the detail of the original source.)
Starting at 1080 is much easier than starting at 720 and going to FHD or 4K, as there is more original detail data for AI to work with.
I hope this helps…
