I have a question concerning frame rate conversion from 18 fps to 25 fps in After Effects.
Rather than just adding an extra frame-copy to each third frames or so with the pulldown technique, I prefer a more sophisticated method in order to avoid jerky playback of fast moving scenes. I watched Andrew Kramer’s video tutorial (http://library.creativecow.net/articles/kramer_andrew/fps.php) and downloaded his plug-in.
The problem is that I have a scan of an 18 fps super-8 film made with the “Müller HM73 Photo framescanner” (http://www.filmfabriek.nl/home.html) resulting in a series of individual photo’s of high quality; superior compared to regular video-scanning. A 20 minutes filmreel however, gives an avi-file of some 75 GB!
I intend to make a DVD of the movies. Therefor, conversion to 25 fps (I live in a PAL country) is needed. I work in HD. Following Andrew’s recipe however, the estimated render time for 20 minutes is in excess of 30 hours! I have tried to lower the filesize by first using Media Encoder. I can not keep the frame rate at 18 fps and converted it to 25 fps, then used the Remove Pulldown in AE Interpret Footage and then Andrew’s trick – but without success.
Anyone who has an idea how to speed up this process?
My HW and SW is as follows: Intel i7-2600 LGA1155 processor on an Asus P8Z68-Vpro motherboard with 16 GB RAM. GTX570. Windows 7 with SP1. Production Premium CS6 updated till today.
Thanks for your response, Pete
Thanks for the tip; I’ll check it out!

Re: Frame Rate Conversion from 18 to 25 fps
I checked the suggested website and – although that product looks great – noticed that my wallet started to protest.
Surfing the internet further for solutions, Creative Cow came to rescue with a video tutorial of an existing feature in After Effects: http://library.creativecow.net/articles/harrington_richard/Converting- Frame-Rates/video-tutorial
Following that method and then importing the AE composition into Media Encoder (which provides for an additional conversion to HD 1920x1080 and using the codec in my editing card Blackmagicdesign Intensity Pro outputting to a TV-monitor) I achieved exactly what I wanted.
The rendering time of the combined AE en ME is now some 1½ hour instead of close to 1½ days!
