Who=20 doesn't hate those annoying logos that networks love = to place=20 over TV shows? If it's a white semi transparent logo, = it can=20 be removed from an AVI file. DeLogo doesn't work with = MPG, so=20 don't waste your time. First step is to = install the=20 DeLogo filter for vdub. Next we will = open our AVI=20 and find suitable frames to work with. You = will need 3=20 frames as shown below. The first is easy, just a pure = white=20 frame the same size as the video you are working with. = It=20 doesn't have to be from the video, just the EXACT same = size,=20 and pure white. The second is a good clean shot of the = logo to=20 be removed against a black background. Be sure to save = these=20 as BMP with names like frame1 & frame2 so that we = can load=20 them as a sequence later in vdub. Now we need to create a frame = to use for=20 analysis. Use the same black background frame, and use = a paint=20 program to color in the logo area with pure red as = shown=20 below. Going outside the lines is ok, just making a = red box=20 will work, just not as well. Name this something like=20 analysisframe and save as BMP. Now we can close out the = video, and load=20 the 2 frames in vdub. Just "open = video file"=20 and browse to their folder and open the first image. = Vdub will = automatically load=20 the second in the sequence. Now open the "video" tab = and=20 select "filters". Here is where you load the DeLogo = plugin, do=20 so and double click it to load. Here is the = DeLogo=20 screen: 1. Under "mask properties" you = will see a=20 button to load your analyse frame, do so. 2. Press = show=20 preview. 3. Press sample frame 4. Use the = preview=20 browse window to move one frame forward to frame 2. = Press=20 sample frame again. Voila, your logo is now = gone, and=20 masks created! Before doing anything else, = save the=20 deblend, alpha, color and repair masks to disk. They = can be=20 used again. Also, TURN OFF "alpha to repair" slider! = All the=20 way to zero, as it will blur your video, not good. = Now,=20 while previewing the black background frame, play with = the=20 "deblend shift" and "deblend falloff" sliders until = the logo=20 area blends in as close to perfect as possible. Make = sure you=20 do this now! When done, click "close" and then "Ok".=20 Okay, so we took the logo off one frame, = let's do=20 the entire video! Please be SURE that you have not = edited=20 anything out using vdubs delete selection feature. If = you do=20 edit before applying DeLogo it will get frames = confused. Go to=20 "file" and select "open video file". Browse to your = AVI and=20 open it. Once it opens, you should see that the logo = has been=20 removed, but the frames without a logo may look like = they have=20 a cookie cutter hole in the logo's shape. To get rid = of this=20 we need to scan through the video and make note of = where the=20 logo appears and when it disappears for a commerical = or=20 whatever. If the logo starts at frame 400 and is = on the=20 screen until frame 10000 we will note this as = 400-10000. Now=20 say it comes back from commerical and the logo = re-appears at=20 13500 and stays there until 22356 when there is = another=20 commerical break. Note this as well and keep going = until=20 you've covered the whole video. Now go to "video" = again,=20 choose "filters" click on Delogo (it's already = applied) and=20 where it says "on frames" we will type in the frames = we want=20 processed. In our example the logo began on frame 400 = to=20 10000. Enter it as 400-1000, then a comma, and the = next set.=20 Our example would look like this: = 400-10000,13500-22356, etc=20 etc. DO NOT play with anything. Don't reload = the=20 analyze frame or ANY other of the masks we saved = earlier. DO=20 NOT preview the video and press the "sample frame" = button, it=20 will screw up your work. Ok, now press = "close", press=20 "ok" and check out your logoless video. You may now = cut out=20 your commericals or whatever and frameserve to your = favorite=20 MPEG2 encoder. =20 =20 =20 =20

Matt D,=20 I gave your method a try and it works as well as = I've ever=20 been able to do using long range samples from the = target=20 video. This is definately a quicker method.

This definately makes the testing process = of=20 whether using the DeLogo filter will work or not a lot = faster.=20 Thanks Norman, I have not yet figured out = how to=20 use this filter in AviSynth.

Norman-=20 It should work with avisynth. Haven't = tried it=20 myself, but I'm sure someone has. Gadgetguy- = Some=20 logos just can't be taken off cleanly. It's usually = due to=20 their construction, or even crappy source video. Some = fault=20 may rest with the plugin, but these two reasons are = usually=20 the culprit. Thankfully you understand that like any = tool,=20 sometimes DeLogo is useful, sometimes it's not. = Smurf-=20 Yes, we've gone around on this again and again. If you = must=20 have every millisecond of logo off, most channels have = you=20 beat. That Spike example only works during the 97% of = the show=20 where the logo isn't moving or sparkling gold. I'd = rather have=20 100%, but c'est la vie.

If anyone would like to see a = moving=20 example of DeLogo, right click this link and save as. I = will leave=20 this up a few days. Be warned, it's 10 megs, and to = save space=20 I encoded the video at 1/2 D1, so there is some minor = noise.=20 Who can tell me what logo I took off? =20 =20 =20 =20

Barnabas,
