phil_the Posted April 17, 2020 Share Posted April 17, 2020 I am trying to overlay two video clips. I found the answers in this thread to be really useful: http://nch.invisionzone.com/topic/25627-using-mask/ However the example there with the flying saucer is using a mostly dark coloured image on a fairly dark background. My video clips are taken outside and are quite light in colour, especially the sky area, and I find that I am seeing dark lines around my cut-out area. If I use feathering that actually makes it worse and I get thicker lines. I intitally thought the problem might be due to the lighting being very slightly different in the two clips, but I was able to reproduce the problem just using a solid white image overlaid on two tracks.Using the default reactangular mask I don't see the lines, but if you alter the mask shape they appear. Any ideas how I can remove or reduce these lines? Thanks Phil. Link to comment Share on other sites More sharing options...
borate Posted April 17, 2020 Share Posted April 17, 2020 Install the latest Windows version and see if the issue persists. For licensed users upgrades are free for up to six months from purchase date. After that, VP will continue to fully function but a fee will be required in order to register the newest. Retain your old install file and registration info. Link to comment Share on other sites More sharing options...

Nationalsolo Posted April 17, 2020 Share Posted April 17, 2020 Hi This problem of a faint dark line around masked areas was noted in earlier versions of VP. The Devs traced it to a glitch with the way transparency of the mask edge was created. It was corrected in recent versions. Nat Link to comment Share on other sites More sharing options...
phil_the Posted April 17, 2020 Author Share Posted April 17, 2020 Thanks. Here's the finished video. It worked well in the end, and the feathering was useful to blend the edges too. There is still an issue with the sound getting out of sync, but that was a problem with my original playback and recording, not to do with VideoPad.https://youtu.be/Oh6ohtnSEfg Phil Link to comment Share on other sites More sharing options...
