There is a wonderful tool that does exactly what you want. You can get it here:

You can apply this filter within Vegas using Satish Plugin Pac, available here:

It's almost eerie how well it works with alpha logos (transluent logos). Its not bad for getting rid of the Date and/or 12:00 Time from those people who refuse to read their camcorder manual.

Oh yea, it also works well at eliminating those annoying "for your Considera....err, ah..... subtitles, ya, that's right, those annoying subtitles.

I downloaded the plugin and the plugin pack adapter that John suggested. However, when I open the adapter in track FX and select the delogo plugin and click save frame, like the plugin suggests, no save frame diolog box appears. So I can't get the plugin to work... any help is greatly appreciated!

I'd suggest you try using VirtualDub instead of doing it in VV.

VD is free.

Virtual Dub doesn't support MPEG II.

Oops. You are right. I hadn't used the plugin for awhile and I forgot about this. The PluginPac is wonderful, but it doesn't always let you get to every part of every plugin, especially when they require two passes, or when they try to access the video directly from the plugin dialog box.

This plugin does work inside of Vegas, but to take the snapshot of the frame, you must do either one of the following:

1. Open the video inside of Virtualdub, load the Delogo plugin and take the snapshot there. You will notice that there is a Preview button that appears (which is missing when the plugin is loaded inside of Vegas via Plugin Pac). Click on this, move to the frame you want to use, and then click on "Save frame" on the Analyse line. I recommend going this route because you will get exactly the right resolution (720x480 for NTSC) and the right file format (BMP).

2. You can take a snapshot directly from the Vegas timeline. You have to have preview set to Best, and there are several other settings that must be set correctly. There are several scripts that you can use which will temporarily set all your settings to those required to get a high-res snapshot and then set your settings.

Once you use either of the above to get the snapshot, you bring the snap into your photo editor, and then use pure red (255 for the red channel) to paint over the logo. I find it best to not use a soft edge when doing this painting.

Save this image as a BMP file, load Delogo in Vegas (via PluginPac), and then click on "Load ..." on the Repair line and load the image you just created. Don't change any of the default settings. Close the setup dialog. Check your keyframe icons before exiting the PluginPac to make sure you have the Delogo filter operating on the portion of the video you want to correct, and that the filter isn't linearly appearing and disappearing over time (this, of course, is a problem with any filter in Vegas -- the curse of the keyframes I call it).

Hope this helps! This filter is amazingly effective.

P.S. One additional hint. Try to choose a frame where the logo is over a uniform color. You can get fooled if the logo is over a highly textured portion of the video, and you can also get fooled if it is over pure black or pure white. Also, as the author notes in his instructions, don't be afraid to make the mask a little larger than the logo. If you fail to cover a few pixels at the edge of the logo -- especially on logos that have an aliased edge (i.e., they fade softly away at the edges), you will find that you have an annoying bit of the logo still showing through.

Thanks for the help John I really appreciate it! I did everything you said and the only problem I am still having is getting the plugin to work. I painted the BMP file and loaded as instructed into the plugin pac. The plugin was then applied directly on the video track. I set the start keyframe and checked sequence start af the begining of the video and made a keyframe at the end of the video and checked sequence end. I then played back the video and the plugin didn't seem to have been activated. I tried also doing this in virtual dub and checked repair preview in the plugin and the video is all black... any ideas or help is greatly appreciated!

It's always tough to know what you might be doing wrong. If you are reasonably comfortable with Virtualdub, I'd recommend initially working with DeLogo directly in Virtualdub because it eliminates the additional complication of PluginPac.

When I first used this plugin, I too had some problems. As I remember, the first problem was clicking on the wrong "Load" button. There are four rows of different ways to use the plug in. Make sure you use the "Load" button on the last of these rows, the one labeled "Repair."

Also, if you captured the image in anything other than DeLogo itself, and the image is not exactly the correct number of pixels (720x480 for NTSC), the DeLogo mask will be offset and won't work.

Finally, make sure you use pure, opaque red for the mask. If the red intensity is set to even one level less than maximum (254 instead of 255), nothing will happen. Unfortunately, I use an obscure editing program called Photoimpact, not Photoshop, so I can't tell you how to assure that you are painting with pure red.

First, click here to see what the dialog box should look like after you have loaded the repair image:

DeLogo Dialog

(this image will only be available for a few weeks). Change your settings to match these exactly (although the name of your BMP file will of course be different).

Other things to check:

1. Make sure "Display Output Video" is checked in Options.
2. Make sure "Compression" (in the Video menu) has been set to a valid compressor for the type of video you are using (although within Virtualdub, the filter should still work even if this is mis-selected).

P.S. to my last post: Make sure you save your mask file as a BMP file.
