I noticed these “jumps” in static backgrounds as well. For me, the “jump” occurred after about 25 frames. I think I’ve found a temporary solution:
Create 4 copies of the original video sequence.
Then trim these copies at the beginning:
- Remove 5 frames from the first copy
- Remove 10 frames from the second copy
- Remove 15 frames from the third copy
- Remove 20 frames from the fourth copy
Then render all 5 files (including the untrimmed original file) with SLP. Due to the time offset, SLP seems to enhance each clip slightly differently; the results are not exactly identical.
Then overlay the 5 SLP results in a video editor (layer opacity from bottom to top: 100%, 50%, 33%, 25%, 20%) and make sure the clip ends are flush in the timeline so that all 5 clips are in sync. The beginning of the timeline should look like a staircase (due to the time offset of the 5 clips).
Afterward, I could no longer see any “jumps,” and overall the result was more realistic (smoother skin, less exaggerated, no overly sharp edges, etc.).
The only downside: It’s much more time-consuming and labor-intensive. But I find the result convincing, and depending on the project or scene, it could be worth the effort.
I’m still testing whether the result can be improved even further by overlaying a video track with SLM on top of the SLP result (layer opacity set to 30% or 50%, for example)…
