Firstly I discovered that you need CS 5.5 in order to import an image = sequence into Adobe Media Encoder. We're on CS 5.0, so no luck there. Then I discovered that whatever Adobe package is on my machine, it = doesn't include Premiere Pro. So no luck there. Likewise it doesn't have Final Cut or Compressor, so no luck there. I thought I'd try FFmpegX - the Mac gui front end to ffmpeg, but it = doesn't support image sequences either. I didn't have the time today to = figure out how to use ffmpeg from the command line, so I'll save that = for a rainy day. Opening up the sequence in Quicktime Pro takes AGES, possibly longer = than the image sequence runs for anyway, and unless I stand there with a = stop watch there's no easy way to benchmark Quicktime Pro, as you'd have = to include the incredibly long time it takes to open the sequence before = you can begin exporting it. But in my case of opening a 20 minute = 1920x1080 image sequence, it took about 30 minutes just to open the = sequence, which is a very long time to wait before you can even begin to = export it... I don't know how long it took to actually export, as again = you'd need a stopwatch to measure it accurately. But it definitely = wasn't faster than real-time... Inside AE CS5.0, with multiprocessors on and AE utilising 6 of them, the = image sequence begins to render very quickly. Initially AE predicts a = total rendering time of 30 minutes (for a 20 minute video). This is = looking pretty good until about 1/3 of the way through, and then AE = begins to slow down. And then it slows down more. The further through = the render it gets, the slower it renders. Eventually it finishes in 62 = minutes. But I'd guess that it took about 30 minutes to render the = first 80%, and another 30 minutes to render the last 20%. This is on a = freshly booted 8-core machine with no other apps running, 16GB ram. I said in my original post that converting image sequences to quikcktime = is not one of AE's strengths. But I may have been wrong, because so far = it's the best I've got! -Chris On 23/02/2012, at 4:23 AM, Phil Spitler wrote: > I will be interested in seeing your results from the ffmpeg test. >=20 > Great tip, thanks Lloyd. >=20 > Phil >=20 >=20 > Phil Spitler | Associate Creative Director | Bonfire Labs | t : = 415.394.8200 | c : 415.571.3139 | Bonfirelabs.com >=20 > On Feb 22, 2012, at 3:46 AM, Chris Zwar wrote: >=20 >> Thanks all...
