    Fixing Camera Speed Errors


    I have been given a mixture of tapes and files to put together in to a tiny reel , which is fine. However some of the files are Go Pro recorded at 12 frames or 15 frames as second. I did say to drop the material but for some reason it has been deemed crucial to the reel. Can anyone recommend a plugin or method to get either 25 fps or 29.97 fps without all the juddder.

    I have used smoothcam on FCP in the past but I'm either going to be on Symphony V6.1 or MC V7. I have Boris 7 but never used it for anything like this.

    Please feel free to state the obvious if I have overlooked something simple.


    Thanks in advance for any help.

    There is an application called MotionPerfect that can do this for AVIs. I've looked at it for making smoother slow motion, but it can also be used to interpolate frames when converting up framerates. I ultimately did not buy it, so I can't offer anything truly definitive about it. It's not very expensive. You can check it out at If yo decide to try it, let us know how it worked out (or not).

    If your GoPro files are QT, in the console set "ignoreQTrate = true" and then import them.  Then use FluidFilm to convert them to the rate that you need.  To convert 12 fps to 25 use 48% speed, to 30 use 40%.  To convert 15 fps to 25 use 60%.  I'm sure that if you need to (unlikely, I would have thought) you can work out 15 > 30 yourself!

    I've found that the Blended Interpolated setting gives pretty fair results with minimum artifacts and reasonable render times.

    There is also an "ignoreAMArate" console setting, but I've never used it so I can't say how/if it works.
