Hi gaveitatry,

Please contact me directly with issues like these. I'm just one developer and I only have my spare time to work on Icaros,
but I'll gladly answer your questions and help you with problems, if you contact me via mail or through the dedicated Icaros subforum.
You can find links to both in the Icaros GUI on the About page, or here: Xanashi[at]gmail[dot]com.

Now as for your issue with the thumbnail adornments (movie reel borders):
These borders are added by Windows and not by the shell extensions themselves. Icaros only provides an image to Windows Explorer,
which is then post-processed by Windows, where it sometimes crops and adds borders to the thumbnails.

It is possible to enable/disable these borders/adornments via the Windows Registry. This affects all thumbnails instantly,
and can be applied to entire media genres (video/image/music files) or single filetypes (mp4, mkv, flv etc).

If you contact me, I can give you some more info on how to accomplish this using regedit.
The next version of Icaros will give the option to turn the video reel adornment on and off for video files.

To sum up, both bugs are not really related to Icaros, as it completely up to Windows how the adornments of every file
is handled.

I won't force you to continue troubleshooting this if you have everything working now, but you are more than
welcome to write to me if you wish to revisit these issues and find a solution.

UPDATE: Jun 10, 2016

Yeah there is definitely two bugs that I can see.

Bug #1 - Yesterday, when I had a MP4 video on my desktop, refreshing the desktop removed the reel decoration. For some reason, that is not happening today. However today, if I cleared my cache, it gave all my PNG images on my desktop a reel decoration. But if I refreshed my desktop, the reel decoration disappeared from two of my four PNG images. Wwhy half? why not all of them? Why won't the reel decorations stick? Why do they disappear on desktop refreshes? This inconsistency is so weird and frustrating.

Bug #2 - I have PNG excluded (by default), but I still get reel decorations on some of my PNG images. I don't remember if Icaros always put reel decorations over PNG images or not. But if I have PNG listed in Excluded, shouldn't that prevent PNG files from getting reel decorations? I associate reel decorations with movies not images. It would be nice to just see the images themselves without any reel decorations on them.

UPDATE: Jun 11, 2016

I reinstalled Media Preview and enabled Image Thumbnail Adornmenet with Border Style disabled and that got rid of the reel decorations on all my images. So that solved that problem. Media Preview has me interested now because I always thought that it was a bad program because it always showed a 123 on the bottom right corner in their screenshots and I didn't want numbers with my reel decorations. But I was wrong. There are no numbers. It's just like the reel decorations in Icaros. Now that I am getting more familiar with Media Preview, I might give it a chance some time. For now I will disable it and see if Icaros does what I need it to do. I've been using Icaros for years and I solved the problem with remembering window size and position and I solved the problem with reel decorations on PNG files. So I might be good now. Glad I got it all worked out... hopefully. Only time will tell.

UPDATE: Jun 11, 2016

I spoke too soon. Now I can't get those reel decorations to appear on my MP4 files using Icaros. I am starting to think that I need to use Media Preview instead. So I will install it once again. This time I will uninstall Icaros first an see if Media Preview will do what I need it to do.

UPDATE: Jun 11, 2016

I uninstalled Icaros. Insalled Media Preview. (By the way, I always do clean installs. I delete registry files and hidden AppData folders.) Media Preview seems to be working flawlessly. I get the reel decorations on MP4 files just like I wanted, and Desktop refreshes don't make the reel decorations disappear. Conclusion: Media Preview works just like I need it to and Icaros failed me. Making the switch now. No more Icaros for me. Thanks though. I am glad that Icaros is still around. Media Preview hasn't been updated since 2014 and if it ever quits working maybe you guys can carry the torch and get yours working and then there will still be a program out there for generating video thumbnails. But that's only if you get yours working. Keep at it. Hope you get it working perfectly one day.

Update. After installing other programs (Media Preview) and reverting back to 2.3.0, I ran into a problem where some of my PNG files were getting reel decorations and I don't quiet remember ever having reel decorations on PNG files before. It bothered me. So I tried to install 3.0.0 again hoping that I can find a way to get rid of those reel decorations once and for all. I haven't figured it out yet, but I did resolve an earlier issue. I found out that 3.0.0 has option in UI settings to remember window size and position. Perfect! That's what I needed. I can stick with 3.0.0 now. I just wish it worked with MP4s as well as other file formats (the reel decoration doesn't always appear unless I drag the file over to the Icaros window and the reel decoration disappears on desktop refresh) and even though 3.0.0 has PNG and JPG and GIF excluded I still see reel decorations on some of my PNG files and I don't know how to get rid of them.

Ease of use 9 of 10 Functionality 8 of 10 Value for money 10 of 10 Overall score 8 of 10

In 2.3, and possibly previous versions, I could never get a thumbnail to generate for some files such as .MP4. I even manually added .MP4 to the extension files.

So today, I decided to upgrade to the newest 3.0.0. Oh my God, it was horrible! It generated a thumbnail for MP4 files, but as soon as I right clicked desktop and hit Refresh the thumbnail disappeared. But my main complain is that in both the x84 and x64 versions, the Icaros window takes up entire screen. If you resize the window, close out of it, and open it up again. Guess what? It takes up the entire screen again!

So I have no choice but to revert back to 2.3.0 where at least the window can be made small and stay small. I want to like this program but I might need to look around for another program that actually gives me thumbnails for all video extension types.

Thanks anyway. You tried.

I reuploaded a new version of RC 2 about 30 minutes later with this problem fixed.
I'm not sure if videohelp got this new version yet.

Try re-downloading RC 2 and give it another try. :)

Thanks for the RC2 release. But when I update to 3.0RC2, I can't launch the IcarosConfig.exe, it didn't display the main window.
Do you have any idea? When I roll back to RC1 and everything is fine. Windows 10 x64

Great tool! Thanks for the nice work!
But there is a little mistake about the Chinese translation, is that "ui settings" translation is not "介面设置", the correct one is "界面设置".

I downloaded this program and had a lot of problems with it. Icaros did indeed generate thumbnails for all of my video files as advertised but it didn't always seem to play nice with Windows 7. On numerous occasions I would open a folder containing video files and the screen would lock up while Icaros was generating icons--I would get a swirling circle in the folder for several minutes or more before I could do anything. This did not happen every time I opened a folder with videos but it became enough of an issue that I finally uninstalled icaros--and all of my problems with the folders went away. I liked having thumbnails for everything but not at the expense of the computer freezing.

Great Tool!!!
I tried a lot of other tools for displaying thumbnails for mkv and flv files.
But I didn't found a working tool. E.g. I tried Haali Media Splitter but this tool created some black thumbnails and other were completly white.
With Icaros I can even display thumbnails for .vob and .flv files.
Thanks for programming this masterpiece.

Installed and seems to work fine/stable. Allows me to get thumbnails in Windows Explorer for FLV files when I couldn't get them before. Requires you to install the LAV filters. So if you have the Haali splitter installed, you will need to uninstall that first.
