ImageGrab, Extract Images From Video

24 Ago/10

You sometimes may want to create a screenshot from a video on your computer. Maybe you want to write about the video and need a screenshot to visualize a scene, maybe you want to distribute the video, and maybe you just want to catalog all your videos and want to add screenshots for identification purposes.

Whatever the reason, ImageGrab is way more comfortable than the manual way of pressing PrintScreen on the keyboard, and processing the image in an image editor.

ImageGrab requires that Haali Media Splitter, or ffdshow are installed on the system before the program can be used. The software reminds the user after installation if that is not the case.

Videos are then loaded by drag and drop, or by using the file menu. The beta version had a few problems with that, as it was sometimes possible to load videos without problems, only to find out that the same videos could not be loaded at a later time with the two codecs not installed. This problem should go away if the codecs are installed.

Videos that have been loaded can be played, and the usual playback controls are offered. It is furthermore possible to jump right to a specific position in the video.



Images can be grabbed by left-clicking on the video or pressing F12. A smaller thumbnail of the image appears and the image gets saved on the local system. Ctrl-C will copy the snapshot to the clipboard instead, from where it can be processed further.

ImageGrab definitely has its uses, the beta version however is not completely stable yet, and most of the interface is in French, which makes it harder for users who do not speak French.

The program offers a few features that applications like VLC do not offer. This features include taking automated screenshots, and extensive command line options to grab images without user interface.

It is up to the user to decided if its worth the troubles of installing another application.

ImageGrab is available for download at the developer’s website. Both the stable version 4, and the beta of version 5 are offered. We suggest to stick with the stable version for now, until the beta quirks are sorted out.

Users who need several thumbnail images instead can take a look at Auto Movie Thumbnailer, Thumber or Image Grabber.
