Notice: 1. The duration of the imported video must be greater than or equal to the duration of the audio, otherwise, an error will occur. 2. Try not to place the product close to the mouth, otherwise, the part of the product near the mouth may become blurry, and it will need to be slightly cropped.

After modification on 2026.2.28, the speed has improved significantly.

This program maintains good quality even for longer durations (unlike other AI long videos where quality gradually deteriorates) and avoids GPU errors (out of memory).

If e-commerce requires higher video quality, please adjust the frame rate to 30; however, a frame rate of 30 will increase the runtime duration.

If your video has subtitles or watermarks, it is recommended to use this program to remove subtitles or watermarks first (https://www.runninghub.cn/ai detail/2002757601127460866).

This application integrates the function of lip-sync replacement, so the runtime is slightly longer. A 48G graphics card (PLUS) can generally produce 2 seconds of video in 3 minutes. If your (membership single task duration) is 40 minutes or 60 minutes, you can generate up to 7 videos of 40 seconds each at once.

The initial resolution of this application is 576*1024; do not compare it with those initial low resolutions of 480*848 for speed.

Vertical default aspect ratio: 576*1024; horizontal 16:9 default height is: 1024*576 (the values must be multiples of 16, such as 576*1024, 720*1280, 864*1536, otherwise errors may occur).

The proportion of people in the video and the proportion of people in the picture should be similar; this will result in better video effects.
