Remove watermarks, logos in video files

• Start up VirtualDub/VirtualDubMod and load your avi file that has the logo you wish to remove.

• Click 'File', then 'File Information.' Write down the size of the video (blue box). Then click 'OK.'
• You need 3 images of the video.

• Open your image editing software. Create a new image the exact same size as what you wrote down earlier. Name it 'frame1' and save it as a .BMP file. (If you are using paint, click on 'Image' and then 'Attribures. . .' to set the size and click 'OK')

• For the second image we just need a good clean shot of the logo on a black background. In the VirtualDub window, move the slider until you see a good image of the logo on a black background. Once you find one, click 'Video', then click 'Copy source frame to clipboard.'

• After that open your imaging editing software program and click 'Edit', then click 'Paste.' Then name it "frame2" and save it as a .BMP file.

• For the third image, we take the last image made and color in the logo 'red.' A red box over the logo will also work. It just won't look as good (This is what I did). Be sure to save it with this filename 'analysisframe' and save as .BMP.

• Now go back to your VirtualDub screen, click 'File', then click 'Close video file.'

• Now, Click 'File' again, then click 'Open video file...' and select the first frame you created (frame1.BMP) then click 'Open.'

• Now click 'Video' at the top, then click 'Filters....' The 'Filters' screen will now pop up, from here click the 'Add' button and select 'DeLogo 1.3.2', then click 'OK.'

• The DeLogo filter screen should now pop up.
• Now, first load the 'analysisframe.bmp' you made earlier in the 'Analyse' box via the 'Load' button.
• After that, click the 'Show Preview' (The button will show 'Hide Preview' when Show Preview is activated) button at the bottom left.
• After that, click the 'Sample frame' button .
• After that, use the preview browse window to move one frame forward (you can press this key to automatically move forward one frame) .
• Then press sample frame again.

• Now, make sure you 'Save' each 'Mask Property.' Just click the 'Save as...' button and save it somewhere on your hard drive.

Important

• Next slide the 'Alpha to repair' slider to the left until it says '0.'
• Now with the preview window still showing, slide the 'DeBlend shift' & 'DeBlend falloff' until the logo disappears.
• When you are finished, click the 'Close' button , then click the 'OK' button on the next screen.

• We have only taken the logo off 1 frame. We need to do the whole video. Go ahead and click 'File', then 'Open video file' and open up your file that you are removing the logo from. When you first open it up, it may appear the logo is already gone but, its not gone from all the frames.
• To get rid of the logo in all frames, we need to scan through the video and make note of where the logo appears and when it disappears.

• The logo in my video started at frame 0 and ended at frame 3313. So I clicked 'Video' at the top, then 'Filters', then I clicked on 'DeLogo' , then the 'Configure' button. Here I set the frames I wanted to remove the logo from, (ie. 0 -3313) (red). Then I clicked 'Close.'

• If the logo appears then disappears at certain spots, just write down where the logo appears and at what frame it disappears and enter it in accordingly.
• That is, if the logo starts at frame 100 and is on the screen until frame 1000 we will note this as 100-1000. Now say the logo re-appears at 1300 and stays there until 2200 then, go to 'video' again, choose 'filters' click on 'Delogo' (it's already applied) and where it says 'on frames' we will type in the frames we want processed.
• In our example the logo began on frame 100 to 1000. Enter it as 100-1000, then a comma, and the next set. In our example would look like this: 100-1000, 1300-2200, etc.
• DO NOT modify anything!
• Do not click any button before you click the 'Close' button. Don't reload the analyze frame or ANY other of the masks saved earlier.
• DO NOT preview the video and press the 'sample frame' button, if you do, it will mess up all the work done and you will have to start over.

Done!!
