UI Video Output

SizeType, Size

Select how to specify the video size in Size: either by area specification with SquareSide or by long side specification with LongSide.

• SquareSide specifies the area, which helps prevent VRAM shortages due to aspect ratio differences in post-processing with Refiner.
• LongSide allows intuitive specification by long side length, but may cause VRAM shortages when refining images close to square.
  • If you adjust for square images, non-square videos may become very small.

The video area affects VRAM usage quadratically. Please be careful of VRAM shortages.
Doubling the side length quadruples the area and VRAM usage.
Refer to MegaPixels just below for the amount of VRAM consumed.

However, video area also directly affects quality, so adjust while balancing with the next Seconds setting.

Seconds

Specify the approximate length of the generated video, typically around 3~5 seconds. The model's recommended value is 5 seconds.
If the video motion is slow, post-processing frame interpolation may increase playback speed by about 1.3x and reduce the playback duration.

You can generate longer videos, but motion and other quality may decrease.
Video duration affects VRAM usage linearly: doubling the seconds doubles VRAM usage.

There are rumors that specifying 10 seconds or more may cause the video to return to the start image.
However, this is not the intended use for the model, so it may affect motion quality and other aspects.

BaseFrameRate

Set the base frame rate for the generated video.
If you plan to use post-processing frame interpolation to make it 4x 60FPS, set this to 15 so playback speed remains unchanged before and after interpolation.

Note that this does not affect the speed of motion in the generated video content.
It only changes the playback speed.

NumFrames

The number of frames is automatically calculated from the seconds, but you can specify the frame count directly if needed for any reason.
Specify as a multiple of 4 plus 1.

GeneratedVideo

You can check the video generated with the specified size and length.

MegaPixels

Displays how many pixels will be processed with the video size and length specified in Size and Seconds, in units of 1 million pixels.
Use this value as a reference to determine what values you can use without causing VRAM shortages.

ResizedImage

You can check the start image resized to the size specified in Size.
The actual size in pixels is displayed at the bottom.

GeneratedVideo

Displays the generated video while saving it.
Note that this is a preview before post-processing is applied.

FAQ

How to increase video playback speed

Set BaseFrameRate to 20 with the premise of setting 60FPS x1.3 Speed in post-processing frame interpolation.
As playback speed increases, the video length and playback duration will be shorter.
