Changing the FPS of a video

vivek wrote on 4/3/2014, 5:38 AM

There is an edited video (done on some other editor, by someone else) which is currently set to 29.7 (30) frames per second. I realize that to give the video a Movie look, I need to have the output at 24 frames per second. Can I re-edit this video at 24 FPS to achieve the desired output? If so, how? Thanks in advance! 

cheers, 

Vivek

Hi

To get the Movie (Cinema) look you really need to shoot the original footage at 24fps in Progressive mode so that each of the 24 frames is recorded with all the lines of information at once in the top to bottom scan.

However, you can attempt to recreate this with other footage by starting a new project and choosing a 24fps frame rate in the Movie settings (E key), then dragging the footage to the timeline and ignoring the pop up which asks if you want to modify the Movie settings to match the imported footage. Previewing should show you an approximation of how the converted frame rate will look and exporting a section as 24frames Progressive (24P) should show you the final effect. Whether this will look okay in terms of your expectations of the movie look and also not look too jerky during pans etc. remains to be seen with viewing your test on the target viewing device.

Hi

IMHO any frame rate conversion is going to cause some sort of problem, particular where there is panning or movement

In particular going from 30 fps down to 24fps is going to show significant jitter due to, assuming the video is progressive, losing 2 out of every 5 fields and applying a  3:2 pulldown.

If the video is 30fps interleaved then you have an even bigger problem because there are not have enough frames to get a smooth progressive video .

To get that movie look is more then just about changing framerate and, IMHO, it would be better to leave the framerate at 30 fps and apply effects to give the video that 'recorded on film'  look and may be add in a little image weave to emulate projected film.
