I second what Martin said. Nothing sucks more than waiting a few hours or days for a render to find a cliche in the middle of a video. Also if you lose power or anything else that causes you to have to re-render. With image sequence you can just render the missing or corrupted frames instead of starting completely over.
Hi Wayne, it's Wayne here.
I will add my 2 cents here.
Thank you Sir. I too come from the old school (63 yeas old). Very good advice. I started with computers back in the early 1980s. No internet like today (Just BBS). Thank you once again for your input. And I have to laugh; both are names are Wayne. Just a fun fact. The name Wayne comes from a Wainwright,(Thats a wagon wheel maker) . So I just love When you use a wagon wheel as example in your course. BTW are you from Australia? Always loved Kangaroo's as a child. If so, please can you send me pitchers of one or Joey ( Hope I spelled that correct.)
For me, it depends... If I know it's going to take more than a few minutes to render a full animation (something that frequently happens for me when I do a Cycles render), I'll render the frames and then edit them together. Like some of the others have mentioned, there's very little more frustrating than having something render for hours only for something to fail along the way and having to start all over again. If you render the frames as output, if it fails halfway through, you only have to render the one that failed and the remaining images. If I know the full animation can be rendered in 10-15 minutes tops (often the case if I'm rendering using Eevee), I'll just go ahead and render as a movie.
Oh my goodness !!! Thank You so much. When I was about 5 use to watch a Saturday program called Joey and fell in love with the idea that I would ride in there, (What at the time called their pocketbook).
