Enabling AVCHD MTS/M2T/M2TS Video File Thumbnails in Explorer

Assuming you have a codec installed that allows you to view AVCHD files in Windows Media Player (such as CoreAVC),here’s how you can get those videos’thumbnails into the Explorer thumbnail view. I wholly admit I stole this info from some forum somewhere,but most of my searches turned up some lamer’s warning about using regedit,and a refusal to post the fix because of it. So I’m going to post it again in a concise article.

Don’t freak out. Regedit isn’t that damaging. In fact in the 12+ years I’ve been working with Windows,I don’t think I’ve ever seen a computer explode due to a change in regedit,especially when you follow directions.

Anyhow,open Notepad and copy in the following:

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\.mts\ShellEx\{BB2E617C-0920-11D1-9A0B-00C04FC2D6C1}]
@="{c5a40261-cd64-4ccf-84cb-c394da41d590}"

[HKEY_CLASSES_ROOT\.m2t\ShellEx\{BB2E617C-0920-11D1-9A0B-00C04FC2D6C1}]
@="{c5a40261-cd64-4ccf-84cb-c394da41d590}"

[HKEY_CLASSES_ROOT\.m2ts\ShellEx\{BB2E617C-0920-11D1-9A0B-00C04FC2D6C1}]
@="{c5a40261-cd64-4ccf-84cb-c394da41d590}"

Save this as "AVCHD Thumbnails.reg"and run it. Accept the merge. You may or may not need to reboot to apply the change. Hit F5 in your Explorer window to check.

    I am sorry,but your registry settings doesn’t seem to reveal my AVCHD .m2ts files. i tried it twice. do you have any other solution for this ? i can play m2ts files in media player,but my vista ultimate x64 doesn’t show thumbnails of the video files. reply me on (address removed) thanks.

  • What does your .reg file look like? Did you remove any preceding spaces when you copied the text in (you should)?

    Currently,I’m on a Windows7 Ultimate 64-bit OS,the directions posted above have worked for ME;

    However,on my friend’s system,a user with Windows Vista Home Premium 64-bit OS,the results were not the same. He’s tried the text with and without spaces. Please help.

    I am aware this thread was posted 2009. Thank you kindly in advance.

  • I think it has something to do with trying to use a 32-bit utility to generate thumbnails for 64-bit Windows Explorer. I don’t have a 64-bit PC in front of me,but I would suspect that there is a 64-bit ShellEx path in the registry that you could try the same thing on and see if it works. Also,I’ve seen a utility called ShellEx64 which might help,though I’ve never tried it myself (http://www.shellex64.com/).

    I’ll be getting a 64-bit PC late next week,so I could try it out then.

    Found the solution. In his case,we installed the necessary codecs;once installed,Explorer displayed the thumbnails.

    Thank you for your help.:) It has been very enlightening.
