FCP stuttering H.264 clip
Canon 7D clip is stuttering in the FCP viewer.
I’ve transcoded the clip to ProRes 422. The clip was shot at 1080 with a shutter speed of 125. When I play the RAW CLIP in quicktime, there is no stuttering. Additionally, when I play the captured clip in quicktime player, its smooth with no stuttering.
As soon as I load the clip in the viewer or drop it into a timeline, BOOM, stuttering.
I’ve also opened the transcoded clip in Cinema Tools and it plays perfectly.
Sequence settings: 1920×1080 29.97fps Apple ProRes 4444 Pixel Aspect: Square Field Dominance: None

What drive are you playing your media off of?

ProRes4444?
That codec requires more bandwidth, 330Mbps I believe. What is your media stored on? A firewire hard drive might not cut it, although, I never worked with ProRes4444, so I can’t say for sure.

Hi Chris,
Its an internal drive. Here’s where it gets stranger. My wife is on the same setup as mine and the same raw clip transcoded by her machine, plays smooth in FCP viewer and canvas. I copied her sequence settings tab for tab.

I think its a playback setting. I took the stuttering clip and exporting to a quicktime movie (make movie self contained).
I then opened the exported .mov clip in the FCP viewer and it stutters. BUT….If I open the exported clip in quicktime, its SMOOTH.

You shouldn’t edit with media on your internal (OS) drive.
Your results will vary.Chris Tompkins

Shouldn’t the frame rate be 60?

Sorry… I meant the shutter at twice the frame rate, so 60.

Nope. shutter can be anything above 2x the frame rate. the most important proof is that the clip plays smoothly on my wife’s machine.
