Attribute Explanation
Directory refers to the directory where the file resides.
Filename refers to the filename(s) the movie, image or sequence refers to.
Sequence true if the filename refers to a whole sequence of images, false if it refers to a single image or movie.
Video Streams Number of video streams in movie file
Audio Streams Number of audio streams in movie file
Subtitle Streams Number of subtitle streams in movie file
First Frame First Frame to Display in Movie or Sequence files
Last Frame Last Frame to Display in Movie or Sequence files
Frame Start First Frame with Data in Movie or Sequence files
Frame End Last Frame with Data in Movie or Sequence files
Width The current width of the image, sequence or movie.
Height The current height of the image, sequence of movie.
Real Width The real width of the image, sequence or movie in case the width is a proxy.
Real Height The real height of the image, sequence of movie in case the height is a proxy.
Aspect Ratio The actual aspect ratio of the image (ie. resolution width / resolution height ).
Pixel Ratio The shape of the pixels in the image.  A pixel ratio of 1 refers to square pixels (like those of a printer or monitor).  A different value refers to pixels for other media (usually, NTSC or PAL video).
Position X The X translation of the image.
Position Y The Y translation of the image.
Scale X The X scaling of the image.
Scale Y The Y scaling of the image.
Display Window The Display Window of the image (OpenEXR).
Data Window The Data Window of the image (OpenEXR).
Depth The color depth of each channel (8-bits, 16-bits, or 32-bits for float images).
Image Channels Number of image channels in the image.
Color Space Color Space of the movie file.
Color Range Color Range of the movie file.
Render Pixel Format Render Pixel Format for movie file.
Rendering Intent The embedded rendering intent for this image.
Gamma The built-in gamma of the image (if any).
Input Color Space (ICS)
 The OCIO Input Color Space (ICS) for the image when using OpenColorIO. This transform turns, for example, a log camera image into a linear one.
IDT Transform
 Any Input Device Transform (IDT) CTL (Color Transformation Language). This transform turns, for example, a log camera image into a linear one.
Inverse Output Transform
 Any Inverse Output Transform (IOT) CTL (Color Transformation Language). This transform turns, for example, a Rec.709 image into a linear one. It contains both the IODT and IRRT together.
Inverse Output Device Transform
 Any Inverse Output Device Transform (IOT) CTL (Color Transformation Language). This transform turns, for example, a Rec.709 image into a scene referred one.
Inverse Reference Rendering Transform
 Any Inverse Reference Rendering Transform (IRRT) CTL (Color Transformation Language). This transform turns, for example, a scene referred image into a scene linear one.
LMT Transform (1..etc)
 Any Look Mod Transform (LMT) in CTL (Color Transformation Language). These transforms handle color corrections, like those of a bleach pass, or an ASC_CDL SOP (Slope Offset Pivot), Sat (Saturation) correction. It may also work in a more friendly image color space such as ACEScg.
Render Transform
 Any embedded CTL (Color Transformation Language) rendering transform.
ICC Profile Any embedded ICC (International Color Consortium) profile in the image.
Format The format of the image or movie file.
Line Order The line order of the image (if applicable)
Memory The amount of memory the image uses.
Disk space The amount of disk space the image uses (only applicable if the image is on the filesystem)
Compression Compression type used to save the image.  Some formats allow changing the compression type before saving.
Compression Ratio The percentage of compression (ie. the difference between the space the image uses on memory and the space it uses on disk)
Creation Date The date the image was created or last modified.

Metadata Tab

If an image contains EXIF, IPTC or other attributes, they will be listed in this tab. With the RMB, you can add, toggle modification or remove any of the attributes.

Adding an Attribute

You add an attribute by going to
RMB->Add Attribute
in the media info window.
When adding an attribute, you need to select the type of attribute, the keyword name for it, as well as its value. Note that the type of attribute is kept only in OpenEXR images. All other formats that support attributes (MIFF, PNG) will turn any attribute into a string attribute.

Modifying an Attribute

If you want to modify an attribute, you need to toggle its state with the
RMB->Toggle Modify->Attribute
. As a shortcut, you can select
RMB->Toggle Modify->All
which will toggle all attributes. Once it is active, you can type in the new value for the attribute and then press TAB to exit and have the value take effect. If the value does not match the attribute type, you will get a popup with an error in it.

Removing an Attribute

You remove an attribute by going to
RMB->Remove Attribute
in the media info window. When removing an attribute, you need to select the keyword name for it.
