VirtualDub estimated time keeps going up...?
 

I've been messing around with Avisynth and VirtualDub with varying results. I've used scripts I've found in various places, here, YouTube, other forums...I've even asked ChatGPT to write a script or two, though they invariably come back using something I neither have nor can find. Sometimes I use what I find as-is, just copy/paste; sometimes I slightly modify, sometimes I try to Frankenstein them together, probably unwisely. :P

Anyway, when I start rendering in VirtualDub, I get the popup window with the processing information. A handful of times, it's taken a relatively short time, just a few hours, but more often than not, it will display the estimated time as a few hours....then I check back and it's gone up an hour or two. Once or twice it's started out saying something like 4 hours remaining, then creeped up to 8 hours. So I'll leave it going when I leave for work, check it when I get back and it says it still has 11 hours remaining, after running for 10 or 12 already. I think there was one that went from 4 or 5 hours estimated when I started it to more than 30 still remaining AFTER I'd already given it 10. At what point can I safely assume I've messed something up? :D
