pulldown problem

Hope this is not evolving into a 24 against 30 pointless battle.
you guys are all right from my point of view:

On one side the medium IS the message, and the frame rate can and should be also used accordingly to the language we want to to adopt for the specific project.
If our project talks the language of pure, high quality images then the higher frame rate we can use the better. If our projects wants to shout classic cinema then 24 is our magic number. And if our idea is better expressed by a lo-fi aesthetic, why not go down to 18?

On the other end it is very important to consider where you are gonna show your final product. I am sitting in europe, so the perceptive difference between 24 and 25 fps doesn’t even touch me, but I believe 25 for me or 30 for you would be a wise choice for anything that is broadcast.

Finally, If the “refresh rate” of the human eye is approximately 12 fps..(of course it varies with the lights conditions and so on) the 6 frames difference between 24 and 30 should be almost imperceptible, especially to the untrained eye of the final user. to “see” any difference we should grow that fps exponentially and go to 48, 96 etc.. but then, where would we show it?

persistence of vision in film is maintained by flickering the shutter on the projector 3 times per frame to trick your eyes. 24 fps is actually bellow what is necessary to mainatin persitence of motion, it has been tested to be around 60-70 fps for most people.

i agree that if your goal is to appear ‘film-like’ then 24p is a good place to start (although there is a lot more to looking like film than just the frame rate). but there seem to be an increasing perception that 24p is just plain better, and that is not at all true.

When using AE you should always export it in a lossless format *.avi This is done by rendering. If you are going to export stuff it is my experience to better use Premiere to do this. AE is bad at this. So you got to keep rendering at high quality untill you reach your last post processing batch (in your case AVID) and then export to other formats. Also suggest checking all export options for streaming etc.

Ps if you send the project files I will render it for you. Please use “www.yousentit.com” I have some time left (for now)

AE makes a distinction between “export” and “render”. Other apps do not.
In AE, exporting is done from the File>export dropdown.
Rendering is done through:
– composition>make movie or
– composition>add to render queue or
– various still image rendering methods.

It’s not true that you should always render to a lossless AVI file format. It depends on how you expect to use the file after rendering. If you are sending the file to another app for more processing, yes, you should use a lossless format such as AVI, Quicktime Animation, 8-bit (or 10-bit) uncompressed, Avid Meridien Uncompressed and so on. The codec depends on where the file is going and what you expect to do with it.

However, you can also render test videos to many other formats, so lossless AVI is not the only choice.
