I sometimes make comps at 24 frames per second instead of 23.976 inside of my tutorials but some people have asked, “What is the correct frame rate for film?” Well, there are a lot of various situations to consider but here are a few good rules.
- The frame rate for digital film work is 23.976 so you should use this if you are making a cinematic commerical or movie about robots.
- Some video editing applications abbreviate 23.976 as 23.98 but AE requires the more specific frame rate.
- Film or not, you should work at the frame rate of your source material.
- Non-standard frame rates such as 12 and 15 are great for creating animations for the web or even flash.
- If you have multiple fps sources try to conform things to your output format.
The reason I sometimes use 24 fps instead of 23.976 is probably because I’m lazy and web video can be non-standard without many problems. Of course, it is probably good practice to use standard frame rates so that you can easily author to DVD or Blu-ray. Hope this helps but be sure to investigate your specific workflow, so that you don’t run into problems in the middle of a project. Remember PAL & NTSC standards may vary.
