    Dear All,

    I have shot a nice TV spot on 35mm and my film house gave me 24p hd files to edit.
    I have edited quite fine but I want to convert the file to 29.97fps for broadcast. Is this the correct thing to do and how on earth do I do this.
    Edited on FCP and added graphics on AE7. I want to export at 29.97 but whe I do, I get jitter.

    Thanks
    J

    Check the Help on “pulldown”.

    You may also want to take a look at Standards Conversion from http://www.nattress.com which converts between NTSC, PAL and 24p right within FCP. Within AE Magic Bullet (I know it goes from 30i to 24 p but may go the other way too) and Twixtor may do it as well. Andrew Kramer also has a tutorial on frame rate conversions you can look at (videocopilot.net)that does not involve any 3rd party plugins.

    Remember that when converting from 24 to 30 fps you are repeating repeating some of the fields (I can never remember which ones). This becomes a problem when you have slowed down a shot or when a shot pans quickly. Some frames will have fields that are so different from one another it causes a stuttering effect. So you might still get some stuttering even after your pulldown.

    Thanks for that but now I have another problem.
    The footage I digitized was at 126 MB/sec or so, and after I did my after effects work, the data rate seems to be 28Mps. This info is from the FCP program window. What am I doing wrong for me to lose so much data?

    this is probably a better question for fcp forum, but you said you had hd to edit? what preset did you use to edit in? did you edit in a non-hd preset? it may be that your original footage was in a fatter codec than what you editted in, like a differnce in dvcprohd and hdv, and fcp may have converted/rendered the footage to the lesser codec. or possibly the footage was edited in a standard def preset, where the same effect would probably occur.

    i haven’t worked much in fcp, i’m just theorizing…
