This plugin is built into ImageJ 1.41b or later. Supported AVI files can be opened
using the File>Open command or by dragging and dropping on the
This plugin opens uncompressed 8-bit and 24-bit AVI movies as a stack. The latest version, by
Michael Schmid, adds support for YUV formats, the ability to specify the starting and
ending frame, an option to convert to 8-bit grayscale, an option to open the movie as a virtual stack,
along with many bug fixes.
PC users can use the free VirtualDub program to uncompress AVI files.
Macintosh users can use QuickTime Pro
to convert QuickTime movies into uncompressed AVI movies. Note that AVI files with audio tracks may
fail to open.
HandleExtraFileTypes plugin and you will be able to open AVI movies with a “.avi” extension using File/Open
or by using drag and drop.
Another way to open an AVI movie in ImageJ is to use VirtualDub (Windows only)
to convert it to an image sequence and then open the sequence using ImageJ’s File/Import/Image Sequence command.
To create a sequence in VirtualDub, use the File/Save image sequence command,
set “Minimum number of digits
in name” to 3 or more, and check “Windows BMP” as the “Output format”.
On Windows, the Video Capture Tool
macro can capture and display video using the VirtualDub program.
Only a few formats are supported:
Uncompressed 8 bit with palette (LUT)
Uncompressed 8 & 16 bit grayscale
Uncompressed 24 & 32 bit RGB (alpha channel ignored)
Uncompressed 32 bit AYUV (alpha channel ignored)
Various YUV 4:2:2 compressed formats
PNG or JPEG-encoded individual frames.
Does not read AVI formats with more than one frame per chunk
Palette changes during the video not supported
Out-of-sequence frames (sequence given by index) not supported
Different frame sizes in one file (rcFrame) not supported
Conversion of (A)YUV formats to grayscale is non-standard:
All 255 levels are kept as in the input (i.e. the full dynamic
range of data from a frame grabber is preserved).
For standard behavior, use “Brightness&Contrast”, Press “Set”,
enter “Min.” 16, “Max.” 235, and press “Apply”.
2002/07/11: First version 2002/07/16: Opens 8-bit movies faster 2002/10/02: Bug fixes 2004/07/18: Better “this is not an AVI” error message 2005/01/24: Open AVI files using File/Open or drag and drop 2005/02/14: Uses file name as window title instead of “stack” 2005/10/20: Opens 32-bit (ARGB) AVIs 2007/10/19: Fixed bug that could cause “Map size(0)>=1” error; fixed progress bar
Support for several other formats added, especially some YUV
(also named YCbCr) formats
Uneven chunk sizes fixed
Negative biHeight fixed
Audio or second video stream don’t cause a problem
Can read part of a file (specify start & end frame numbers)
Can convert YUV and RGB to grayscale (does not convert 8-bit with palette)
Can flip vertically
Can create a virtual stack
Added slice label: time of the frame in the movie
Added a public method ‘getStack’ that does not create an image window
More compact code, especially for reading the header (rewritten)
In the code, bitmapinfo items have their canonical names
Support for PNG and JPEG/MJPG encoded files added
Retrieves animation speed from image frame rate
Exception handling without multiple error messages
Adds support for 16-bit grayscale AVIs created by
MIL (Matrox Imaging Library), thanks to a patch by Reinhard Mayr
Jesper Soendergaard Pedersen added support for extended (large) AVI files,
also known as ‘AVI 2.0’ or ‘OpenDML 1.02 AVI file format extension’
With virtual stacks, reads the ‘AVI 2.0’ index (indx and ix00 tags).
Fixes a bug where too many frames are read.
Minor updates & cleanup for integration into ImageJ.
Based on a plugin by Jesper Soendergaard Pedersen, also reads the ‘idx1’ index of
AVI 1 files, speeding up initial reading of virtual stacks also for smaller files.
When the first frame to read is > 1, uses the index to quickly skip the initial frames.
Creates a unique window name.
Opens MJPG files that do not contain Huffman tables.
