We have a repository of video animations of varying codecs/resolutions/frame-rates/etc that are currently playing on rotation in VLC player as a corporate display. I've been asked to add a corporate banner or logo to this, so that the videos play underneath the banner or so that the logo is embedded prominently. VLC's facility to add a logo (Tools/Effects and Filters/Overlay tab) does this but sizes logo relative to the video, so the logo scales from tiny to dominating the screen for different videos.
I know there are ways to add logos to videos using for example FFmpeg, but I'm reluctant to process all these videos for that purpose (cost/benefit..) and as it'll reduce quality.
I'd be very grateful for advice on a way to add a banner/logo in a more seamless professional way to a playlist, perhaps using a layer-based approach where you can specify a banner frame above the video frame. Or alternatively is there a way to control Windows screen output in this way? Thanks in advance.
