How to change framerates or footage interpretation
(MAC OS X) USING APPLE CINEMA TOOLS TO LOSSLESSLY CHANGE FRAMERATE
If you have Final Cut Studio then you have a copy of Cinema Tools
Find your new files
It will take a few seconds to go through all the clips. They will be in the original folder in a new folder called “Conformed”. You can either leave them there or move them back out again.
(WINDOWS) USING CINEMARTIN CINEC TO RECONFORM YOUR FILES
Download Cinec from http://www.cinemartin.com/cinec/. You can use the Free or Pro versions.
Check your original file format
You will now havea list of the imported files. The framerate should read 25.
Change the output type
Select all clips. In the Common Preset dropdown menu, change this to your desired format. Apple ProRes (LT) matches the original’s format.
Next go up to the FPS and type in your desired value. Note: If you type in 23.976 and hit enter, this will display 24. Do not worry, it will encode to the correct value. Finally choose a directory for your processed file.
Repeat for all clips. Hit Encode.
Check out the results
Once the files have processed, your Movie FPS and Duration will be different. This shows that you have the same frames but they are playing back at a different speed.
