DeLogo is a filter for VirtualDub that can fade out static elements inside videos without risking too much damage to the original content. The plugin embeds two removal schemes that can work together to erase stubborn elements, which are difficult to process using traditional methods.
It is important to acknowledge that DeLogo can only process static videos, therefore motion graphics or animations are out of the question, at least for the time being. On the other hand, considering that the application hasn’t been updated in quite a while, there’s little chance that it will be further improved.
The filter comes wrapped in a lightweight package, which includes a VDF file that ought to be placed inside VirtualDub’s plugin section by simply copying it to the dedicated subdirectory in the program’s installation folder.
DeLogo is operable only from VirtualDub’s interface and sports a somewhat simple and unappealing appearance. The GUI is divided into several sections, adjacent to parameters such as mask, analysis options and reconstruction commands.
First and foremost, you should choose the type of function for the filter, namely deblend and repair. The first one can process alpha blended logos, while the second one deals with opaque objects.
Most of the analysis is done by the filter’s engine, although users do have access to some configurations, such as mask properties, which can be loaded and saved on demand and also, to repair parameters, like depth, power and pixel aspect.
In conclusion, DeLogo provides a relatively non-complicated way to deal with logos and watermarks. Although the success ratio is pretty good, don’t expect the output to be totally flawless. The areas that are covered by such objects may bear a certain degree of blur.
