Enabling Thumbnail Previews For MP4 Files

[jdvideo]

Hey all.

After googling, it seems as though the only way to have MP4 thumbnail previews is to add this reg fix to the registry:

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\.3gp\ShellEx\{BB2E617C-0920-11d1-9A0B-00C04FC2D6C1}]

If MP4 files are the only files on my PC that don't have thumbnail previews, wouldn't I only need to add this to the registry?:

[HKEY_CLASSES_ROOT\.mp4\ShellEx\{BB2E617C-0920-11d1-9A0B-00C04FC2D6C1}]
@=”{c5a40261-cd64-4ccf-84cb-c394da41d590}

Any info and/or advice is appreciated.

Let us know how it works.

I found a regpatch a couple of months ago that was supposed to add thumbnail view for MKV and MP4 and after installing it, my computer crashed every time I tried to open a file or a program. There was no regfixpatch to undo the damage so I had to reinstall Windows since the OS had become unusable.

[Krispy Kritter]

It was my understanding that Windows can create thumbnails for all files in which WMP is the default player and has the proper codecs for playback. As I don't use WMP as my media player and I don't use thumbnail view for my folders, I can't verify.

Thanks for the replies DarrellS and Krispy Kritter.

Well, I haven't added the regfix yet. I'm still undecided on whether to add the regfix or convert the MP4 files to AVI files.

Yea, I was wondering about that. I currently have the K-Lite Codec Pack installed on my comp. The default player for MP4 files is Media Player Classic (which was part of the K-Lite Codec Pack). I have tried with WMP11 as the default, but no luck with preview thumbnails either.

Try this:

- Click Start -> Run -> type:
regsvr32 shmedia.dll
- Click OK
- Reboot

Thanks for the suggestion, but no luck. Only the MP4 files are currently absent of preview thumbnails.

Yea, that was one of the first things that I tried. Unfortunately, I'm not sure if Explorer recognizes an MP4 file in order to utilize the Haali Media Splitter thumbnail extraction option.

[DarrellS]

That's the guide I used the first time that left my computer unusable. Not sure why. I tried it again except I did not install the MKV registry patch and it showed the thumbnails just fine by setting Haali splitter to yes for thumbnails. I did not set the offset though.

Since that worked, I got brave and installed the MP4 patch and now my MP4 thumbnails show up. I must've had something else installed before that was conflicting with the Haali splitter cause I could not do anything without Windows crashing.

Yea, that's why I'm hesitate about installing a regpatch at this point. I'm wondering if there are any other options out there.

Does anyone know how well the Pazera MP4 to AVI converter works? I've read a few reviews here and there, but wanted to get some other opinions and/or advice as well.

I have a similar problem now, except it is affecting all IMAGE (not video) files. Can you tell me a registry hack that will fix this issue? I've already tried clearing the thumbnail cache, and all other non-registry-hack solutions that people have suggested.

[SpectateSwamp]

My app can play the first few seconds of all my video files and a lot lot more....

You don't need a "hack", you need to try and determine what caused it not to work.

It would likely be much faster and easier to simply take the time and perform a fresh install of the OS.

Just for information to original quote... In additon to the normal shown, several others may be present represented by:

@="{9DBD2C50-62AD-11D0-B806-00C04FD706EC}" PotPlayer
@="{c5aec3ec-e812-4677-a9a7-4fee1f9aa000}" Icaros
@="{c5a40261-cd64-4ccf-84cb-c394da41d590}" Normal Codec

If an entry is present but different, you can google it and usually find out which program is stifling your thumbnails.
