I have no idea if this was real or not and did no testing but it felt to me like my videos would encode the first half faster when I had a fully transparent colour over top of a video track (to align end of track 1 with start of track 2). I then started to just put a separate video track of just a transparent colour over top of everything and it honestly felt like my videos were encoding much faster at no loss of quality that I could see. Roughly half the length to encode or so. Is this real in some way or purely a figment of my imagination?
I got curious about this so I tried to reproduce it. I couldn’t. The transparent export was 22% slower. It’s possible that if you were working with short small files, then they got cached in RAM from the first export and were faster to read from cache on the second export. That’s just a guess.
From the menu, there is a View > Jobs option that brings up a jobs panel. It shows the elapsed time of each export if you want to get scientific about results.
When I thought it was happening it was with files I hadn’t exported before. And yeah I was observing the total export time in the jobs folder. I don’t know if it’s relevant but my GPU is okay while my processor is trash.
Well this is at least reproducable for me. I chopped a bunch of video down, 4 tracks, transparencies in layers and then one final transparency covering it all. 22 minutes long, 1080p, took me 50 minutes to encode. Noticed I’d messed up and forgot to cut out a segment, took the encoded video, chopped out 3 minutes, and just went to export that without any transparency over it and I check an hour later and it says it’s a quarter done so I stop that job, restart the job but with a transparency covering the entire thing and now it says the job should take 40 minutes total.
