Just thought I’d share this segment of a slideshow I created featuring some of my snapshots of my neighbourhood.
I used keyframes of size and position to create gentle zoom/pan effects. The opening title is an overlay HTML I did utilising Elusien’s Webvfx framework. (I did have some problems getting this to work - I will begin a thread about this, and how I solved it, when I get a chance). Music track is my own piano composition.
Very nice, but you can see what is called a “moire effect” on some of the slides, which is that shimmering from animating fine details. I have read that you can reduce this problem by adding a tiny amount of blur or un-sharpening (Sharpen filter, Amount < 50%). It is not clear whether to put this blur/sharpen filter this before or after the Size and Position. I think it goes before, but that does run much slower than placing it after, which will probably soften the result too much.
Thanks Dan. Yes, I can see the Moire effect, especially on the opening slide (Not too obvious to me, but it’s there). No fault of Shotcut’s, I think - in retrospect there’s way too much sharpness on that photo!!
I processed the original in gimp using the sharpness filter and increasing the saturation (A LOT)!. I’ll re-do the processing of the original. Also I’ll experiment with the blurring filter in SC. I was delighted with the smoothness of the movement of the slides. You have done a great job with the keyframes feature, thanks!!
The mystery continues… I have these extensions: AdBlock, Adobe Acrobat, Google Docs Offline, Norton Identity Safe, Norton Security Toolbar, Google Docs, Google sheets. Just disabled them all. Problem continues: I get this:
