Problem with color gradual changes for long videos #8

Thanks for the release code! I have experiencd severe color changes for long video generation, e.g more than 60 frames. And finally the color becomes oversaturated. Tune off the init_noise_by_residual_thres can alleviate this issue, but the first frame conditioning still makes the color changing aorund.

Another problem is that the unet3d fails to generate images without control_hit, which is not expected as the normal unet2d with controlnet.
