Export

Velocity Lapse can export projects to either MP4 video or an image sequence.

Format

Select either the MP4 video or Image Sequence option to set the export format.

MP4 Video

MP4 video is a widely used video file format (called a “container”). There are two common video codecs used with MP4:

• H.264 (also known as AVC)

• H.265 (also known as HEVC)

Velocity Lapse exports H.264 MP4 video, which is the most widely supported video codec. In the future Velocity Lapse may also support HEVC, which offers up to 50% better compression, and thus smaller video file sizes.

The settings from top to bottom:

Resolution

The output resolution of the video. Some options may be disabled if the resolution of the images are not high enough to export at the a certain video resolution. (e.g: If the images are HD, the 4K option will be disabled.) If options are not shown, your device hardware does not support it.

Bitrate

Bit-rate controls the quality of the output video. Specifically, it controls the data rate of bits per second. Higher values result in more data per second, but also result in larger video file sizes. The actual bit-rate the selected option in Mbps is shown above the Export video button.

FPS

FPS refers to “frames per second”, meaning how many images will be shown per second of video playback time. This changes the length of the final video. Some devices and resolutions do not support 60fps so the option may be disabled or not shown.

Effect

Apply an effect to be applied during export. None (the default) doesn’t apply any effect. Motion Blur applies a smoothing effect simulating long-exposure blurring. Light Trails applies an effect tracing the lightest points of the images, which is especially useful for creating star trail time-lapses.

Image Sequence

Velocity Lapse capture JPG images so you full control over your project and can export the image sequence for use in other applications.

Location

The output location where the JPG image sequence will be saved. This can be changed by setting the folder of the Image Export Save Location setting.

Frames

The number of images that will be exported as an image sequence.

Storage Required

The amount of storage required to export the project as an image sequence.
