make slow mo with footage look like regular speed
In FCP7 whats the correct speed change to speed up footage shot in slow motion. I have some ARRI Alexa footage which was shot at 48 fps and 72fps which I need to play at regular speed. My sequence is 23.98. All my attempts end with a weird stutter. I don’t really like the frame blending effect.

Have you tried 200.167% for the 48fps and 300.25% for the 72fps? I don’t think you should need to use any frame blending for this.

the footage was never transcoded and plays native at 23.98. i think the alexa doesn’t need to be transcoded and records native at Prores and other compatible formats. its 444.
so far it looks like 250% works well, but im going to try those percentages as well.

200% for the 48fps
300% for the 72fpsthis will give a playback speed of 24fps. close enough to 23.976.
when you make the speed changes, turn off frame blending.
i wouldn’t be too surprised if some of your stuttering is due to playing Prores4444 clips with effects.

thanks. what about canon footage which was shot slow mo (59.94) then converted to 23.98?

Math. 59.94/23.98=2.49958
250%

yeah would have never thought to divide that but worked perfectly.
