Choppy slow motion
Hello,
I’m able to get buttery smooth slow motion on my girlfriends macbook pro using FCPX. If I film at 60fps on my sony A7iii Ill slow the speed to 40% on fcpx and its super smooth. Film at 120 fps ill slow it down to 20% on fcpx and it looks so good and so smooth.
When I do the same thing with the same footage on Media Composer the slow motion is choppy and doesnt have any of that smooth butterness slow mo that im able to get with fcpx.
In media composer I used timewarp and tried all the types: Duplicated field, both fields, VTR-style, the footage wouldnt even show up in the timeline display when I tried fluidMotion Draft and FluidMotion.
I’m a huge beginner and I might be missing something but ive looked at every slow motion tutorial for Media Composer on youtube and watched both fundemental 101 and 110 but can not find an answer to why the slow motion is choppy on media composer, but with the same footage I can get smooth slow mo on fcpx. Was hoping someone here might know what could be the problem.
Thanks
Im using using 2020.6 media composer

If you’ve filmed the shot at a higher frame rate than the project, maybe try right clicking on the clip in the bin and select source settings, then change the FPS setting to source, (or maybe it’s project, I can’t remember).
Fluidmotion needs rendering to play. Select the video track in the track selector on the timeline, Park the playhead over the clip, right click and select render at position
You could also try using the fit to fill effect on the clip. Then adjusting length of the clip in the timeline via a trim changes the speed of the clip, although it shouldn’t be any different to using time warp.

OK…lets first talk about how each NLE works with media, because it’s very different. FCX will link to the media, and even transcode that media when necessary, and keep the frame rate, no matter what you project settings. Avid, can LINK to the media, sure, but really wants that media to be transcoded to Avid media. It CAN work with linked media, depending on the codec. But most often you need to transcode. And when you do, you need to make sure to check the KEEP NATIVE FRAME RATE, so that it retains it’s native frame rate. Although Avid has a limit as to the frame rates it will “allow,” and I don’t think it works with 100FPS media. Might top out at 60fps…but don’t hold me to that. I heard something about higher frame rates over 100 not working.
NOW…when you cut that into your sequence, it should have a “T” on the clip. This means it has a TEMPORAL difference. Go into EFFECTS MODE, PROMOTE that clip, and then in the speed graph, change the speed to 100%. It might be at 60% or 80%…in order to play in real time.
OR…you can select the clip in the bin and go into the SOURCE SETTINGS (right click to access that) and change the speed there.
