Increase the audio CFG value for better synchronization. FusionX While it enables faster inference and higher quality, FusionX LoRA exacerbates color shift over 1 minute and reduces ID preservation in videos. V2V generation: Enables unlimited length generation. The model mimics the original videos camera movement, though not identically. Using SDEdit improves camera movement accuracy significantly but introduces color shift and is best suited for short clips. Improvements for long video camera control are planned. I2V generation: Generates good results from a single image for up to 1 minute. Beyond 1 minute, color shifts become more pronounced. One trick for the high-quailty generation beyond 1 min is to copy the image to a video by translating or zooming in the image. Here is a script to convert image to video. Quantization model: If your inference process is killed due to insufficient memory, we suggest using the quantization model, which can help reduce memory usage.一些建议唇同步精度音频CFG的最佳表现为3–5。提高音频CFG值以实现更好的同步。 FusionX虽然它能实现更快的推断和更高质量但FusionX LoRA会加剧1分钟内的色移并降低视频中的识别保护。 V2V生成支持无限长度的生成。模型模仿了原始视频的摄像机运动但并不完全相同。使用SDEdit显著提升了摄像机运动的准确性但引入了色彩偏移更适合短片段。计划改进长距离摄像机控制。 I2V生成单张图像能产生长达1分钟的良好效果。超过1分钟后颜色变化会更明显。对于高质量生成超过1分钟的一个技巧是通过将图像进行翻译或放大将图像复制到视频中。这里有一个脚本可以把图片转换成视频。 量化模型如果您的推理过程因内存不足而终止我们建议使用量化模型这有助于减少内存使用。InfiniteTalk 的使用--mode streaming: long video generation. --mode clip: generate short video with one chunk. --use_teacache: run with TeaCache. --size infinitetalk-480: generate 480P video. --size infinitetalk-720: generate 720P video. --use_apg: run with APG. --teacache_thresh: A coefficient used for TeaCache acceleration —-sample_text_guide_scale When not using LoRA, the optimal value is 5.
