GridVideo
GridVideo[{v1,v2,…}]
creates a video in which each frame is a grid of frames of all vi at the corresponding time.
GridVideo[{{v11,v12,…},…}]
uses the array position of each video vij to create the video grid.
Details
- GridVideo is also known as video collage.
- GridVideo can be used to show multiple videos at the same time. Creating video grids is very common when showing multiple people in a meeting, playing instruments or showing a scene from different view points.
- Any of the grid elements vij can also be a still image or graphics that are represented as a still video for the duration of other videos. Missing can be used to introduce open spaces filled with the background color.
- Options to control assembly of frames are:
-
Background GrayLevel[0.2] background color ConformationMethod Automatic how to conform frames of different sizes PaddingSize Automatic padding size around the output frame Spacings Automatic spacing between input frames - Settings for Spacings can have the following forms:
-
n use n pixels for spacing between frames Scaled[s] use a fraction s of the image size for spacing {specx,specy} use specific spacing for each dimension - Options to control properties of the output video are:
-
CompressionLevel Automatic compression level to use FrameRate Automatic the frame rate to use GeneratedAssetFormat Automatic the format of the result GeneratedAssetLocation $GeneratedAssetLocation the location of the result OverwriteTarget False whether to overwrite an existing file RasterSize Automatic raster size of the output video VideoEncoding Automatic video encoding to use

Create a grid video from a list of videos:
Create a grid video from a 2D array of videos to enforce the position of each video in the grid:
Create a grid video from a list of odd number of videos:
Use Missing to specify where the empty space should be:
Options (4)
Background (1)
ConformationMethod (1)
By default, videos with different frame sizes are conformed using the "Fit" method:
Use the ConformationMethod option to specify how videos should be conformed:
PaddingSize (1)
Use the PaddingSize option to control the padding size around the output frame:
Spacings (1)
Use the Spacings option to control the spacings between the input frames:
Use both Spacings and PaddingSize to add spaces between and around images:
