Video texture: noise, blur, sharpness, grid
The "Texture and detail" page is in the STYLE section. It changes neither the frame shape nor the color, but the pixels themselves. It has fourteen settings. Two more settings of the same group are on neighboring pages. The ranges all work the same way: see the breakdown in how uniquification works.
What each setting on the "Texture and detail" page does
| Label | What it does | Range and units | Default |
|---|---|---|---|
| "Change sharpness" | Strengthens edges. Negative values give blur | percent, from -50% to +50% | on, from -10 to 10 |
| "Adaptive sharpness" | Raises sharpness only where there is detail | percent, from 1% to 100% | off, from 10 to 40 |
| "Overlay noise on the video" | Adds grain. The pattern is new on every frame of every copy | percent, from 1% to 50% | off, from 1 to 5 |
| "Noise reduction" | Removes grain by recalculating every pixel | percent, from 1% to 50% | off, from 5 to 20 |
| "Blur" | Blurs the whole frame evenly | percent, from 1% to 50% | off, from 1 to 5 |
| "Smart blur" | Blurs flat areas, edges stay sharp | percent, from 1% to 50% | off, from 5 to 15 |
| "Add vignette" | Darkens the frame edges | percent, from 1% to 50% | off, from 5 to 15 |
| "Chromatic aberration" | Shifts the red and blue channels apart horizontally | pixels, from -50 px to +50 px | off, from -2 to 2 |
| "Debanding" | Removes steps in smooth gradients | percent, from 1% to 50% | off, from 5 to 20 |
| "Pixelation" | Builds the frame from squares of a set size | block pixels, from 2 px to 30 px | off, from 2 to 3 |
| "Overlay a grid on the video" | Draws a grid of 1-pixel lines over the frame | percent of line visibility, from 1% to 50% | off, from 1 to 5 |
| "Change grid color" | A list of line colors. One random color is taken for each copy | list of colors | off, the list is empty |
| "Change grid size horizontally" | Distance between vertical lines | pixels, from 1px to 500px | off, from 1 to 200 |
| "Change grid size vertically" | Distance between horizontal lines | pixels, from 1px to 500px | off, from 1 to 200 |
Two settings from neighboring pages
| Label | Where it is | What it does | Range and units | Default |
|---|---|---|---|---|
| "Frame border" | "Geometry and framing" | Draws a black border around the perimeter over the picture | pixels, from 1 px to 50 px | off, from 1 to 5 |
| "Frame blending" | "Duration and transitions" | Averages several neighboring frames, motion gets a slight smear | frames, from 2 frames to 30 frames | off, from 2 to 3 |
What depends on what
This page has one nested node - the grid.
- "Overlay a grid on the video" opens three settings: grid color, horizontal size, vertical size.
- With the grid off, these three settings are hidden together with the card body.
- The other eleven settings on the page are independent and always shown.
- There is no grid color list by default. Without it the lines are black.
- If neither grid size is on, the spacing is chosen on its own. It is random, from 1 to 200 pixels, and the same on both axes.
If "Change grid color" is on and the color list is empty, video creation does not start. The check before start shows the row "Add colors for the grid".
Which settings slow down video creation
Every setting on this page redraws the whole frame. The difference is how heavy the recalculation is.
| How much it slows down | Settings |
|---|---|
| Noticeably | "Overlay a grid on the video" together with its color and sizes, "Adaptive sharpness", "Change sharpness", "Noise reduction" |
| Moderately | "Add vignette", "Debanding", "Frame border", "Blur", "Pixelation" |
| Slightly | "Chromatic aberration", "Smart blur", "Frame blending" |
| Almost no cost of its own | "Overlay noise on the video". Grain is computed quickly but makes the finished file noticeably heavier |
What you see at the edges of the range
| Setting | What you see at the edge |
|---|---|
| "Change sharpness" | +50%: light halos along the edges. -50%: mush instead of detail |
| "Adaptive sharpness" | 100%: the filter limit. Fewer halos than with regular sharpness, but fine details start to shimmer |
| "Overlay noise on the video" | 50%: grain is visible on any frame, the file is noticeably heavier |
| "Noise reduction" | 50%: faces and textures look plastic |
| "Blur" | 50%: small text on the video can no longer be read |
| "Smart blur" | The lower half of the scale is unnoticeable. 50%: flat areas are noticeably softer, edges stay in place |
| "Add vignette" | 50%: half of the maximum darkening, the corners are noticeably darker than the center |
| "Chromatic aberration" | ±50 px: multicolored edges are visible at once |
| "Debanding" | 50%: smooth areas become flat |
| "Pixelation" | Already at 4-5 block pixels the picture turns into squares. At 30 px the image cannot be recognized |
| "Overlay a grid on the video" | 1%: micro-noise. 50%: the grid is visible as a grid |
| "Grid size" | 1px: solid fill. 500px: one or two lines per frame |
| "Frame border" | 50 px: on a vertical video this is a noticeable black band around the perimeter |
| "Frame blending" | More than 3 frames: a trail is visible behind moving objects |
Frequently asked questions
How is "Noise reduction" different from "Overlay noise on the video"?
They are opposite settings. "Overlay noise on the video" adds grain, "Noise reduction" removes it. Both change every pixel. The app tooltip calls noise reduction the most effective way to change a video for platform algorithms. The picture still looks the same.
You can turn on both at once. The processing order is then: noise reduction first, then noise overlay. Otherwise noise reduction would erase the grain that was just added.
Which of the two blurs should I choose?
"Smart blur" blurs only flat areas. Edges and text stay sharp, so it is less noticeable. "Blur" blurs the whole frame indiscriminately, including text and faces. For uniquification that goes unnoticed, the first one fits.
Why two sharpness settings?
"Change sharpness" strengthens edges across the whole frame and gives light halos at strong values. "Adaptive sharpness" raises sharpness only where there is detail and gives fewer halos. You can turn on both together, but then it is easy to oversharpen the frame.
Why does the grid look like a real grid?
The "Overlay a grid on the video" slider sets not the cell size but the line visibility. At 50% the lines are almost opaque. For uniquification that goes unnoticed, 1-5% is enough.
Which setting changes the file the most while staying invisible?
"Noise reduction" and "Overlay noise on the video". Both touch every pixel of the frame, and at low values the viewer sees no difference. The breakdown of visibility is in result quality.
