VideoJoin

VideoJoin[video₁,video₂,…]

concatenates all video_i and returns a video object.

Details and Options

VideoJoin is typically used to combine multiple video files in a sequence.

Video objects video_i may have different properties, including frame size and frame rate. The properties are conformed before joining.
Video objects may have different numbers of tracks. Corresponding tracks are joined together.
By default, VideoJoin places the new video under the "Video" directory in $WolframDocumentsDirectory.
The following options can be specified:

AudioEncoding	Automatic	audio encoding to use
CompressionLevel	Automatic	compression level to use
ConformationMethod	Automatic	how to conform frames of different sizes
FrameRate	Automatic	frame rate to use
GeneratedAssetFormat	Automatic	the file format of the result
GeneratedAssetLocation	$GeneratedAssetLocation	location of the generated asset
OverwriteTarget	Automatic	whether to overwrite an existing file
RasterSize	Automatic	raster size of video frames
SampleRate	Automatic	sample rate to use
SubtitleEncoding	Automatic	subtitle encoding to use
TransitionDirection	Automatic	direction of the transition
TransitionDuration	Automatic	duration of the transition
TransitionEffect	Automatic	transition effect to use
VideoEncoding	Automatic	video encoding to use
VideoTransparency	False	whether the output video should have a transparency channel

By default, videos are joined without any transition effect.
Using TransitionDurationdur, videos are overlapped by the specified duration dur during which the transition happens.
Supported settings for TransitionEffect are:

	None	update instantly without a visual effect
	"Fade"	fade from old content to new
	"Push"	have new content push old content away
	"Wipe"	fade from old content to new using a wiping effect

Basic Examples (1)

Join two videos:

Scope (2)

Join videos with similar properties:

Join videos with different properties:

Properties of the resulting video are chosen such that most input data can be stored in the output:

Options (17)

AudioEncoding (1)

Specify the audio encoding to use:

CompressionLevel (1)

Join videos using default compression:

Use maximum compression:

The choice of encoders affects the amount by which a file can be compressed:

ConformationMethod (2)

By default, black padding is used when images are not stretched to fit the common image size:

By default, a common frame size is used and videos are made to fit in the frame:

Use "Fill" fitting to fill the whole canvas for all frames:

Use "Stretch" fitting to resize the frames:

Perform windowboxing when fitting frames:

Specify a padding value:

Use the RasterSize option to specify the desired frame dimensions:

By default, a common frame size is used and videos are made to fit in the frame:

Specify the padding value:

Specify a different fitting scheme:

FrameRate (1)

By default, the largest frame rate (rounded to the nearest integer value) is used:

Specify the frame rate to use:

GeneratedAssetLocation (1)

By default, generated video files are stored in $WolframDocumentsDirectory:

Specify the output file directory:

Specify the output file path:

OverwriteTarget (1)

By default, existing files are not overwritten:

Overwrite existing file:

RasterSize (1)

By default, the largest raster size is used:

Specify the raster width to use, while preserving the aspect ratio:

Specify the raster width and height:

SampleRate (1)

By default, the largest sample rate is used:

Specify the sample rate to use:

SubtitleEncoding (1)

Specify the subtitle encoding to use:

TransitionDirection (2)

Transition to the left:

Transition to the top:

TransitionDuration (1)

Specify a transition duration for a smooth transition:

TransitionEffect (3)

By default, no transition effect is happening:
