Thanks. [/smile] I came to the same conclusions.
I’m working on a re-mix of the first motorcycle video (by Alexander Thiessen)that really grabbed my attention. The fades are the first of that project. The open is an 11 second fade. The close uses only 3 seconds. I want the results to be within a few frames of the original. There’s no real reason for that accuracy, save I’m being anal about it. LOL
The next challenges are a fading text title, and a scroll for music credits.And at this point the project’s and Shotcut’s wheels fell off.
The scroll, of course, is a non-starter with Shotcut. Life’s too short to program, in HTML, scrolls to the right size and duration. BTDT and don’t plan to go back.
But the fading title should have been a near no-brainer. It wasn’t.
I created, on a separate video track, a block of color (I tried white and I tried black), with the alpha or opacity set to 0. NTL, the block remained persistently opaque. I tried turnin compositing off and on - no change.
As at least a test of concept, I added an HTML text overlay. And stepped into a minefield.
With the block over the main video (starts with the 11 sec. fade in), the best that I could do was fade the block out as the main clip faded in. When I could add the HTML filter, and used an opaque, not fade to/from black, fade. The text didn’t fade and, in general, the results were unusable.
The wheels… I started on my Linux machine (it’s faster) with the portable version of 17.11.07. Almost any time I tried to open or use the HTML overlay, Shotcut crashed. No messages, no clues, no nuthin’. After far too much time, I shifted to my laptop (was wicked fast in its day…). The results were the same. The block remained stubbornly opaque. Touching the HTML overlay produced instantaneous “no Shotcut no more” crashes. Not even the Win10 “we’re looking for a solution” wheeze - just Poof! Gone!
I’d write up a bug report if I had anything more specific than “touch HTML overlay, a color block with less than 100% opacity, and Shotcut dies”. Not much diagnostic info for anyone, except a mind reader, to work with.
