PixTV offers grouping, subtitle removal, extension, and clip re-shoot entry points for AI video revisions

With AI video, getting the first version of the visuals often isn't the end of the story: reference materials pile up, old subtitles get in the way of new copy, a character's action clip ends just as it gets going, or you like the whole thing but one prop isn't placed right. PixTV's grouping, subtitle removal, video extension, and clip re-shoot map exactly onto these specific problems. Seen within the creative process, the use of each step is very intuitive.

Group your materials first, so you spend less time hunting back and forth when discussing options

Character photos, tote bags, cameras, landscapes, and font references are scattered across the canvas; each is useful on its own, but put together they easily become messy. First select the relevant nodes and click group, and a clear boundary appears around them. Then arrange them into a grid, and materials that were previously at different heights are gathered into the same area, making it easier to see at a glance the relationship between the character's temperament, the product, and the environment.

PixTV also supports horizontal and vertical arrangement and custom group colors. When preparing multiple visual directions, you can put city references in one group and outdoor references in another, distinguished by color. Whichever option you're discussing, you look at the corresponding area; once you've decided, you can download materials in bulk from within the group. Organizing on the canvas flows naturally into subsequent production.

When you run into old subtitles, first make room for the new copy

Once materials are ready, coming across clips that already have subtitles is another kind of trouble. Take a street-scene video of a person walking out of a shop: the clothing and environment both work, but the original text at the bottom of the frame doesn't suit the new topic. Directly overlaying new subtitles would be cramped, and cropping the bottom edge might affect the composition—so at this point you can target that line of text.

In PixTV's subtitle removal, you can choose automatic mode or manually draw a selection. In the street-scene clip, a rectangular selection covers the subtitles below; after processing, the original text in that spot is cleaned out, while the person and the storefront remain the main subject of the frame. Next you can rearrange the copy's position, font size, and timing. When you play it back, focus on the moment the person passes through the processed area, then decide whether to use it.

The shot isn't finished yet—write the character's next step

Next is the issue of content length. The cat leans toward the camera and raises a paw; the expression is already captivating, but the clip ends right there. If you want it to continue turning or jumping, you can go into video extension and add a follow-up description in the to-be-generated area after the timeline. The original clip is right in front of you, making it easier to match the action you write to the character's current pose.

The newly added footage appears after the timeline, the cat has content to keep moving, and a single appearance gains further development. PixTV video extension is powered by Seedance 2.5; when using it, first think clearly about "what happens next," then write the specific action. Once the result comes out, watch the before and after together, check the orientation, the starting point of the action, and the relationship to the background, and pick the part suitable for connecting into the story.

If only one spot dissatisfies you, circle those few seconds and re-shoot

Extension solves the follow-up plot, and actions in existing clips can still be changed. In a skateboarding short, the person and the staircase environment already work; what you want to adjust is the placement of the skateboard. Go into clip re-shoot, first select the few seconds on the timeline that need changing, then explain clearly in the input box how the skateboard should be placed, and the edit has a specific target.

Clip re-shoot is likewise powered by Seedance 2.5. When comparing before and after, you can look directly at the positional relationship among the skateboard, the hands, and the staircase, then check whether the action connects smoothly. Write descriptions as "put what where" where possible, and focus on changing one thing per round, so version differences are easier to judge. This approach suits footage that already has a satisfying first version but still needs key actions refined.

From putting materials in the right place, to making room for subtitles, to adding follow-ups and changing actions, the four features each catch one small problem in creation. Next time you face an existing video, first identify the one thing that most needs solving right now, then choose the corresponding tool.
