For image-based watermarks, there are several tools that promise their automatic removal. For example: We PDF Watermark Remover PDF Watermark Remover SoftOrbits PDF Logo Remover All of these are free to try, but require a license to actually produce the desired output. However, the watermark of this specific PDF file (which the OP sent me via email) isn'...

very simply task to perform: use sed: sed -e "s/watermarktextstring/ /g" <input.pdf >unwatermarked.pdf but, after, be sure to repair resulting output pdf pdftk unwatermarked.pdf output fixed.pdf && mv fixed.pdf unwatermarked.pdf all into one command: sed -e "s/watermarktextstring/ /g" <input.pdf >unwatermarked.pdf && ...

Just a little add-on to Dingo's answer as it did not work for me: I had to first uncompress the PDF document in order to be able to find the watermark and replace it with sed. The first step involves uncompressing the PDF document using pdftk: pdftk original.pdf output uncompressed.pdf uncompress now, the uncompressed.pdf can be used as in Dingo's ...

Imagemagick can probably do what you need.

XnView can do this, with the batch processing feature. You select which pictures to transform, from where to where, in which format, and which action(s) to apply to them, including adding a watermark. And it's free!

You should perform the filtering in one filtergraph: ffmpeg -i i.mp4 -i watermarkfile.png -filter_complex \ "[0:v]drawtext=fontfile=/path/to/fonts/FreeSans.ttf:text='TESTING':fontcolor=black@1.0:fontsize=36:x=00:y=40[text]; \ [text][1:v]overlay[filtered]" -map "[filtered]" \ -map 0:a -codec:v libx264 -codec:a copy output.mp4 Use -filter_complex instead ...

I ran into the same issue - the watermark drives me nuts. I managed to come up with a temporary fix for the problem. Note that it involved editing a system hex file, and while I haven't experienced anything going wrong so far, I cannot promise it won't come with negative consequences. Perform at your own risk. You'll need HexEdit (or another hex file editor)...

It looks like either you or any program has set your Windows 7 into test signing mode. This is typically done if you need to install an unsigned driver. As Windows 7 does not allow to install unsigned kernel-mode drives (unsigned/untrusted user-mode drivers are allowed) you need to enable "testsigning" mode in order to install it. To verify whether you're ...

It sounds like the watermark is actually part of the images within the .PDF, and not a separate image rendered over it by whatever you are using to display the .PDF. You may not be able to remove the watermark without extracting the images from the .PDF, running them through an image editor, and then reconstructing the .PDF manually.

Use -itsoffset just before the overlayed input with the same ammount of seconds you are using in the start of the filter (3 in your case) This is maintaining the fade out filter you had, but that filter does not produce any visible results: ffmpeg -y -i big_buck_bunny.mp4 -itsoffset 3 -i alpha.mov -filter_complex "[1:v] fade=out:st=30:d=1:alpha=1 [ov]; [0:...

For me the Winaero Universal Watermark Disabler did the job. I found the instructions here, that boil down to this: Download the Winaero Universal Watermark Disabler. Save your work and close unnecessary applications. Run uwd.exe from the zip-file. It will tell you which Windows version you're using. Click Install. A moment later the program will tell you ...

I did something similar a few years ago. It did not meet all your "hard" criteria. It worked like this: I put a hardly detectable, 2x2 point sized "clickable" area on some random place at one of the borders of a random PDF page. It's not very likely that it get's discovered by accident (amongst the shitload of other very obviously clickable hotspots that ...

I suggest using bgInfo Formerly from Sysinternals (Mark Russinovitsj fame), now bought by MS and hosted on Technet. It will allow you to customize the desktop, showing system information of choice, including logged on user, machine name etc. etc.

Your version of ffmpeg (0.6.1/2010) is a bit on the old side, it might be that the command line format has changed since it came out. Try the latest version.

Short answer: Yes, it's possible. A little bit longer: What comes to my mind at first is pdftk, which can overlay a PDF file with another, see http://www.pdflabs.com/docs/pdftk-man-page/: pdftk in.pdf background back.pdf output out.pdf background < background PDF filename | - | PROMPT > Applies a PDF watermark to the background of a single ...

You could try Rainmeter. Customize an existing skin (there are plenty of skins on internet) that includes all the information that you want to show on desktop. Like this: And you can set it as Position: Stay topmost. It means that it will be always on top even over user windows. You need to make sure that the user can't kill the rainmeter process.

The syntax to add a watermark is slightly different. You need video filters for that, which come bundled with FFmpeg already. I'm not sure you can add a transparent watermark to a separate track. The reason is that the image itself (the PNG "stream") needs to be turned into an actual video track (e.g. with x264) – and since video encoders don't support ...

Some recommendations I understand that ffmpeg is a Linux based application, however I am hoping to accomplish this within Windows 7 64-bit. ffmpeg is available for Windows, OS X, Linux, and other platforms. See the FFmpeg download page for several options. Your first step should be to download a recent build of ffmpeg. It is recommended to regularly ...

This looks like what you're looking for Watermarking Photos (Batch).

You need the bmovl (Bitmap Overlay) option bmovl=hidden:opaque:fifo The bitmap overlay filter reads bitmaps from a FIFO and displays them on top of the movie, allowing some transformations on the image. Also see TOOLS/bmovl-test.c for a small bmovl test pro†gram. <hidden> ...

This may be a couple years too late, but MpegStreamclip (free) for Windows or Mac will put a text watermark in the lower right corner. Just go to the "Adjustments" when you're exporting and type what you want into the Watermark box. It can batch process too, but I haven't tried it with a watermark.

While you do need to use the "Word Art" mode to insert line breaks into a watermark, this workaround does not have any real limitations. It's non-intuitive but it works fine. From Microsoft MVP Stefan Blom Insert watermark using Insert Watermark... Enter some text and click Ok. (You can edit the text later steps.) Double-click on the header area. Right-...

You could run a program downloaded off the internet... Google "remove watermark test mode". This post says that deleting these registry keys (or more likely renaming them) will work: [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SystemCertificates\CA\Certificates\FEE449EE0E3965A5246F000E87FDE2A065FD89D4] [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SystemCertificates\...

Open a (read: elevated) command prompt and type in bcdedit. If the option you're booting from (likely there's only one) has "Test Signing" or such enabled, disable it. bcdedit /set testsigning off should work nicely.

For me installing zlib-devel.x86_64 or something alike helped, e.g. zlib1g-dev on Debian. Try apt-search zlib or yum search zlib

There should be no special issues with WebM encoding. As mentioned by LordNeckbeard, your WebM command lines have both a -vf option and a -filter:v option, but these are the same thing (two different ways to specify the set of filters to apply to the video). You can use multiple video filters, but specify them using a single -vf or -filter:v option. You ...

Get rid of the movie source filter and use -filter_complex (used for filtering with multiple inputs) instead of -vf (used for filtering with one input). Now you can simply list your inputs as usual, and then tell each of your filters which inputs you want them to work with. Since you only have two inputs you can simply do: ffmpeg.exe -i x:\test1\video.mov -...

You can hardcode subtitles into the video with the subtitles filter. The best way to do what you want is with a filterchain, which passes the video through the chain (so the output of the overlay filter becomes the input of the subtitles filter). Filters in the chain are separated by commas. This should not be confused with a filtergraph, which consists of ...

If you use -ss before -i, it will seek to a keyframe. This is quick, but if there is not a keyframe at the specified time then it is not frame-accurate and you may end up with some frames before the seek time, which will effectively have negative timestamps. Since your watermark movie overlay starts at time 0, the frames with negative timestamps will not ...
