  • 25 fps versus 29.97

    Posted by Ashley M. kirchner on April 22, 2009 at 4:41 pm

    I have a Sony W300 point-n-shoot. In video mode it shoots 640×480 at 25.00 fps or in “fine” mode it shoots at 30.00 fps.

    Right now I’m trying to render a clip shot at 25.00 fps out to H.264, and I’m not having a whole lot of luck here. Video seems to be okay, however the audio skips, and I can only assume it’s because of the fps, but I’m not sure.

    Any suggestions here? I tried with the comp set to 25.00 as well as 29.97. Same for the render output module.
