Self Gradient Forcing allows you to expand short video clips into longer sequences. It uses a smart memory process to keep characters, backgrounds, and movement consistent over time. You no longer need to settle for five-second clips. This tool helps your model maintain details even in minute-long videos.

When you open the application, you see a clean main menu. Follow these steps to process your first video:
Click the Import Video button. Select the short video file you want to expand. The application supports common formats like MP4 and MOV.
The tool provides default settings that work for most cases. You can adjust the length of the target video using the slider. Increasing the length uses more memory and processing time. Leave the stability settings at their default values for the best results.
Press the Start button to begin the generation process. A progress bar shows you how much time remains. The software performs a two-pass replay to ensure the video remains stable. Do not close the window while the progress bar moves.
Once the process finishes, click the Save button. Choose a folder on your computer to store your new, longer video.
Most users find the installation smooth. If you encounter interruptions, check the following points:
- Ensure your graphics drivers are up to date. Visit the NVIDIA website to download the latest software for your card.
- Check your internet connection if the application requires an initial check for components.
- Make sure your antivirus software does not block the application. You may need to add an exception for the folder where you installed the program.
- Monitor your disk space. Video processing requires significant temporary storage. Clear out old files if you see a disk full error.
Good input leads to better output. Follow these practices to achieve high quality:
- Use clear and well-lit source videos.
- Avoid videos with excessive camera shake.
- Keep the subject in focus throughout the five-second clip.
- Try different settings if the output loses detail. Lowering the expansion factor often increases stability.
The software uses a technique called Self Gradient Forcing. Traditional models often forget the context of a video after a few seconds. This tool creates a path for the model to remember what happened before. By replaying the video in two passes, the system forces the model to respect the original identity of the subject and the layout of the scene. This method results in smooth motion and natural transitions across the entire length of your new video.
