FAQ: Logo Watermark · Style Drift · Jump Cuts at Splice Points

---

Issue 1: Logo / Watermark in Generated Video

Typical Symptom

The prompt does not mention anything about watermarks, yet the generated video contains a Logo / watermark from another video platform.

Solution

Add explicit constraint instructions to the prompt:

Do not generate watermarks
Do not generate logos

Issue 2: Style Drift

Typical Symptom

You expect a 2D or 3D anime style, but the input reference image has a more realistic style, and the prompt does not emphasize the video style. As a result, the generated video may drift toward a live-action realistic style.

Solution

#### Method 1: Add Style Constraint Keywords

Add explicit style constraint keywords to the prompt:

2D Japanese anime style
3D Chinese-style animation

#### Comparison

!Style drift issue example

Before optimization: Xianxia style drifting to live-action style

!Style drift after optimization

After optimization: maintaining 3D Chinese CG Xianxia style

Video comparison:

• Before optimization:
• After optimization:

#### Method 2: Pre-process the Reference Image

If you need more precise style control, it is recommended to convert the reference image to the target style first before generating the video.

Issue 3: Jump Cuts at Video Extension Splice Points

Typical Symptom

After using the video extension feature to generate a new video, splicing the new video with the original video may result in visible jump cuts or frame regression at the splice points.

Solution

The current recommendation is to fix the cuts in post-editing. Future model iterations will provide a fundamental optimization.

#### Comparison

!Jump cut issue at splice points

Before optimization: visible frame jump or content regression at the splice points (5s, 20s)

Video comparison:

• Before optimization:
• After optimization:

#### Editing Steps (using CapCut or similar software)

• Import the videos to be spliced into CapCut
• At the first splice point, trim 6 frames from the end of the preceding video
• At the same time, trim 1 frame from the beginning of the following video
• Repeat the above steps for all splice points
• Export and check the smoothness of the spliced video

Advanced Tip

Even after frame alignment, minor jump cuts may still occur. When generating extended video segments, it is recommended to end at a transition cut point, and start the next segment with the new scene after the cut. This can further reduce the perception of jump cuts.
