While some video formats can be displayed as thumbnails in Windows explorer, some others like MKV and FLV can’t be. If you set the view to thumbnail mode, all you can see is the icon of the associated program or blank icon for the non-supported videos that isn’t yet associated with any application. In the past we have a tool such as Media Preview to fix this issue, and now here is yet another similar application called Icaros.
The main interface has already come up with a number of video and audio formats such as MKV, OGM, AVI, FLV, FLAC, APE and so on. If you have some other video files that doesn’t show thumbnails, you can add the formats to the “Thumbnail Filetypes Registered” box. According to the developer, the application provides thumbnails for any media formats supported by FFmpeg.
Just providing a thumbnail and leave it just as it is isn’t good enough because the first part of a video is likely an intro screen or even a black screen. That’s why the thumbnail offset is set to 25% by default to make the thumbnail becomes more representative. The offset can be changed according to your liking. However, note that changing the offset won’t probably update the thumbnails. I had tried cleaning up the thumbnail cache, turning on/off the thumbnail via the Group Policy Editor, restart explorer.exe but none of these worked. The thumbnail got updated only after I copied the videos to a new location. If you have any other suggestion you can share it with us here in the comment section below.
Icaros supports Windows 8, 7, Vista and Windows XP. Microsoft NET Framework 4 is required. It also works on 64-bit systems but a user reported that it has a problem in displaying the thumbnails in the Open or Save as dialog. If you encounter such a problem you can activate “Enable 32-bit thumbnailing on 64-bit Windows” in the Advanced option window but it is said that you have to install the 32-bit version of IcarosThumbnailProvider as well to make the feature works.
After you finish configuring the application, click “Activate Icaros” to make it runs the assigned task. If you need to add more file types or change some settings in the future, click “Deactivate Icaros” to be able to do it.
