Video Thumbnails - Using a Different Frame?


Recommended Posts

I would like to find a way to get the thumbnail feature in Windows XP to display something besides the first frame of the movie as the thumbnail. In most cases the first frame of a video is completely black and this makes thumbnail view pretty borring. Windows Vista manages to do this (by displaying what looks like a random frame), and I was hoping that someone knew a way to do this in Windows XP as well.

Thanks in advance!

As much as I hate to bump my own thread (at least give me credit for waiting a couple of days), I would really like to see if there is anything out there that can do this. Windows XP's video thumbnails are almost useless in their current form and it would be nice to have something useable without having to go all out and use Vista.

I have the same problem. :crazy: I don't know who was the master mind behind making the first frame the thumbnail. Like you said, 99% of the time, the first frame is black. I was hoping they'd change that in Vista, but apparently, it will still be the first frame. On the macs they usually choose a random frame, and display that. I would also love to know if there is a patch, or some kind of software that could do that.

Actually, they do fix this problem in Vista (at least in RC1 its there). I am just trying to find some way to do something similar in XP.

What would be truly great is if they had little animated icons so you can differentiate between images and video without having extensions visible or how about a play button watermark over a random video frame(kinda like a smaller version of youtube).

Well, I'm no programmer, so I can't make much of all this. However, it seems to me that it is possible to do this with a simple registry edit.

Actually we have 2 options:

1 decompile Shmedia.dll and find the function that create the thumbnail,and modify it.

2 copy the windows vista dll, MediaMetadataHandler.dll and patch it to Xp.

both things are diffcult to do,

Another method could me make a program that generate the thumbnails and then register it to be on Explorer.exe in thumbnails view.

This can be made doing a shell extension and replacing the default:

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

@="{c5a40261-cd64-4ccf-84cb-c394da41d590}"

I think this can be make but don't know how to start

i think this might be an easy work-around. directshow is used to capture the first frame, what needs to be done is to make it so the filter skips the first few frames, or decodes only a certain frame in the middle, like 1 minute in.

do it with ffdshow and avisynth. add

  Quote
trim(1500,1501)

in the avisynth section and make sure ffdshow is the default decoder. delete all the thumbs.dll files from your folders and visit them again in thumbnail view. you should end up with nice thumbnails for all your videos.

i haven't tried it, im just quoting a good friend of mine, who is a moderator at a video forum told me it will probably work

Omg!! I am going to try it!

What file shoud we modify??, please explain a little bit.

you don't need to modify anything. to roughly quote him:

  Quote
*install avisynth

*install ffdshow, from here http://sourceforge.net/projects/ffdshow-tryout/. make sure you tick avisynth processing/plugin while installing

*click start, then programs, then ffdshow, then video decoder configuration. select avisynth and tick the box next to it. type "trim(1500,1501)" without the quotes, then click ok

*find yourself an xvid or divx avi file and go to the folder it is contained in. click tools, then folder options. select show hidden files and folders and untick hide protected operating system files, then click ok.

*check if there is a thumbs.dll file in the folder your video file is in. if there is, delete it. close the window

*go back to the folder and windows will generate a new thumbnail

i just tried the avisynth/ffdshow idea and my cpu spiked for a while, like it was reeeeeeeeeeeeeeally trying to do something, but in the end cpu use died off and no thumbnails were generated at all.

anybody know an ms engineer who would understand the logic behind wanting this changed/figured out? :D

I've finally came up to this thread, while I was struggling to find this answer, and the proposed solution seems to work.

But I'm facing two problems:

- mp4 & wmv thumbnails are spoiled: upside down, or "frame B" (looks like the rendering has been done without using keyframes

- half of flv have a white thumbnails

regardless of what offset is being used.

It looks like Haali Media Splitter is doing something wrong, or may I solve the problem tweaking ffdshow...

Can someone help?

(the only codecs I have installed are CCCP)

Sorry to bump an old thread, but I have a riff on vktRus's fix that is a bit of an improvement.

There are a few important things to know about this issue.

On 19/12/2009, Shell Integration was removed from Haali Media Splitter. That's the bit that generates the thumbnails! Supposedly it will later be available as a stand alone download. At the moment it's non-existent.

The fix previously posted works around the issue by installing the last version of the Haali filter that still has the feature.

The attached file has the missing component (mmfinfo.dll) which you want to copy to your Haali installation folder and register it.

This gives us a fix that will work with all recent versions of HMS. (You can download the latest here: http://haali.su/mkv/)

The other problem is that occasionally the {BB2E617C-0920-11d1-9A0B-00C04FC2D6C1} key already has a (default) value.

If it is not {327669A0-59A7-4be9-B99E-1C9F3A57611A}, the thumbnail_enable.reg may not replace it with the correct value.

So if you still have a few stubborn thumbnails, go to HKEY_CLASSES_ROOT\.XXX\ShellEx\{BB2E617C-0920-11d1-9A0B-00C04FC2D6C1} (.xxx is your problem file type), and make sure (Default) is {327669A0-59A7-4be9-B99E-1C9F3A57611A}. If not change it or create new keys/strings as needed.

Besides adding extra steps to the readme file, I expanded the thumbnail_enable.reg file to include:

.asf, .avi, .mpe, .m2v, .mpeg, .mpg, .wmv, .ogm, .mp4, .mpv, .flv and .mkv.

Feel free to add or subtract whatever you want.

Btw, some people say that .mkv thumbnails do not work with Haali/CoreAVC. I use CoreAVC and my thumbnails work just fine with this method.

So now you know the root of the problem and have a fix to go with it that you can customize as needed.

Edit: Hmm. Can't make the attachment stick (yes the file is below 2mb.)

Here's a RapidShare link. Maybe someone else can figure out what I'm doing wrong and attach it: http://rapidshare.com/files/410938832/Enable_Thumbnails.zip

    • This super-powerful GaN charger with four ports is 50% off by Taras Buria Some time ago, I reviewed the Cuktech 10, a powerful 100W GaN charger with three ports. It left positive impressions, and since then, it has served me as my primary charger for my phone, watch, laptop, and tablet. Recently, Cuktech offered me the opportunity to take a look at the model 15, a more powerful 140W GaN charger, this time, with four ports. Right now, this powerful charger is available with a massive discount at just $50.99 (with coupon applied). The Cuktech 15 is the same as the Cuktech 10, just slightly bigger, more powerful, and with one extra port. It has a light metallic finish, but overall, it retains the brand's identity and features. The four ports are well spaced out, and the black plastic insert with a cyan rim has a ribbed texture for better grips. Although I live in Europe, Cuktech sent me a US variant with a retractable plug. Okay, I guess. The ability to retract the plug makes it extra portable, which is nice. A high-power 240W five-foot cable is also included. The charger measures 3.11 x 2.56 x 1.26 inches and weighs 0.737 lbs. The Cuktech 15 has four ports: two high-power Type-C ports, one Type-C port with a lower output, and one Type-A port. The first two Type-C ports can deliver a full 140W in single-port mode (PD 3.1 supported), which is nice—no asterisk or caveats here with combined power or something. If you need the full 140W for one device, you get it. Ports are capable of working in the following modes: Single-port Type-C1 / C2: 140W max 5V 2A, 5V 3A, 9V 3A, 11V 6.1A, 12V 3A, 15V 3A, 20V 5A, 28V 5A Type-C3: 33W max 5V 2A, 5V 2.4A, 9V 2A, 12V 1.5A, 11V 3A Type-A: 18W max 5V 2A, 5V 3A, 9V 2A, 12V 1.5A Multi-Port Type-C1 + C2: 100W + 33W or 65W + 65W Type-C1/C2 + Type-C3: 100W + 33W Type-C1/C2 + Type-A: 100W + 18W Type-C1 + Type-C2 + Type-C3: 65W + 60W + 7.5W or 45W + 45W + 18W Type-C1 + Type-C2 + Type-C3 + Type-A: 65W + 60W + 7.5W As you can see, the charger is pretty robust, and it can power two pretty powerful laptops at once and even have enough oomph to charge a smartphone, albeit at a lower power. Another thing worth mentioning is that the Cuktech 15 delivers "clean" power with pretty low pulsations at about 25-50 mV. The rule of thumb is that the lower the pulsations, the better the charger is for your device's battery health. In this area, Cuktech's charger does not disappoint, and they deliver way better results than 100 mV, which is considered a standard for a good charger. Cuktech uses gallium nitride technology, which enables smaller, more powerful and efficient charging. Speaking of efficiency, the charger is rated for 78% average or 64% at a 10% load. When charging at 120W, I received an average of 80-85%, which is good. Of course, when charging at peak power, it gets hot, but not too much. The Cuktech 15 140W usually costs $99.99, which is undoubtedly not cheap. However, right now, you can get it for half the price, which is a very good deal, considering you get a high-quality charger with plenty of ports and very high power output. Like with the Cuktech 10, you cannot go wrong with this one. CUKTECH 15 140W four-port GaN charger - $50.99 | 30% off + a 20% off coupon As an Amazon Associate, we earn from qualifying purchases.

    • KDE's KClock is getting Wayland Picture-In-Picture support by David Uzondu The KClock app for KDE Plasma over the years has received a number of updates, like better integration with KRunner and a dedicated background service (kclockd) for managing alarms. Now, it looks like KDE devs want to add something cool: pop-out timers using the new Picture-in-Picture protocol for Wayland. Image: Kai Uwe Broulik This all started from a simple observation. Kai Uwe Broulik, a KDE developer, saw someone using a small timer window during a presentation and thought it was a good idea. The problem is that achieving this kind of "always on top" behavior is handled differently between the old X11 display server and the newer Wayland. With X11, an application could pretty much do whatever it wanted. If a program wanted to draw a drop-down menu, it would just create a borderless window, place it in a specific spot, and grab all user input. Wayland operates on a different philosophy. As Broulik notes, under Wayland, the application describes what it wants, and the compositor gets to decide how to handle it. A drop-down menu is an XDG Popup. The application tells the compositor which button spawned it, and the compositor handles the placement and behavior. This is much more secure and consistent. It also means an application cannot just decide to keep its window on top of everything else. This restriction prevents a web browser from implementing an overlay video player under Wayland. To get around this in a standardized way, a proper Wayland support model for Picture-in-Picture, or PiP, was needed. Enter the xx-pip-v1 protocol. It is a new protocol designed specifically for creating floating PiP windows, and KWin, Plasma's compositor, recently gained support for it. Because it is an experimental protocol, its use is gated behind an environment variable, KWIN_WAYLAND_SUPPORT_XX_PIP_V1. A new protocol is fine for demos, but it needs a real application to find its weaknesses. So Broulik implemented it in KClock. This work allows KClock to offer pop-out timers and even a pop-out stopwatch in a small PiP window. The user could get system-wide options to control where the PiP window appears, or if it appears at all, and have that setting apply to every single application that uses the protocol. You can check out the merge request on GitLab for more technical details about this feature.
    • Nothing of course; it is just a classic syndrome of MAGA pathology.
    • They use it to assessment's in the UK already. Have a friend who said they basically feed response's and prompt during assessment's for many mental health conditions now (essentially tick boxes these days enough ticks and you got it) the AI can prompt questions to ask if its unsure how to score something. It's really good at recognising fractures and broken bones also.
