Converting 30 FPS to 25

Post by tom hardwick » Wed Aug 15, 2018 9:29 am

Hi team.
My sweet little SJ5k action cam records full HD at 30 (probably 29.97) fps. So far so good, and this plays back in camera through my TV or my phone or laptop just fine.

But my Edius 6.5 editing program doesn't have a 30 fps editing preset, all the options are 25 fps. The problem with this is that any editing I do and subsequent output to USB stick or disc is done at 25 fps, and the interpolation that loses the excess 5 fps causes judder on screen.

Is there a way around this? A program I could use that would do the downconversion from 30 to 25 smoothly before I start the edit? Or any other ideas?

Just to say for those that aren't followers, but the IAC NLE email round robin has continued this thread in a very interesting way. Worth joining if you haven't.

Handbrake https://handbrake.fr/ is a free transcoding tool which will convert frame rates, and most other media properties. I've used it for converting 30fps video from my phone to 25fps. The interface is a bit techy, but the documentation is good.

Thanks Richard. The same link was posted in the NLE thread. But Premiere Elements 15 has been proved to handle the 29.97 fps footage beautifully, whereas my far more expensive (and a good deal older) Edius 6.5 made a botch of it. As they say, 'edit anything', but not without noticeable artifacts.
