  • I think I just found the old thread where the solution to this problem is mentioned (link below). It’s about checking or unchecking “fliter” in the render control tab in user preferences.

  • Thanks a lot, Shane. You’ve been answering a lot of my questions. So, I wonder why some of my 30 fps footage is slowed down 50%, and whether it’s only that way in playback from the timeline or whether it will export that way too.

  • That actually didn’t work. I did as you said but still when I move the sliders in color correction or brightness, nothing happens to the image in the canvas.

  • OK, good to know. Thanks.

  • So far what I’ve done is to simply convert it in MPEG Streamclip to ProRes and set the frame rate to 30. It honestly doesn’t look that bad. But I wonder if it would make a significant difference to do it in Compressor the way you suggest. Do you think so?

  • I think now that the problem is in the sequence settings and rendering. The footage looks fine when I play it directly from the browser, but as soon as I drag it into the sequence and render it, it gets screwed up. The problem is that I don’t know why. I have the sequence settings and the footage matching in frame rate, aspect ratio, and interlacing. What’s even weirder is that rendering screwed up some of the clips but not all of them. One of the Samsung clips I dragged in turned out normal, but the other would stay on the same frame twice in a row for each click of the arrow button on the keyboard. And in regular speed play back it would also jerk around like it was skipping several frames at a time. Just weird.

  • Thanks. Well since writing that comment, I’ve discovered that the frame skipping only occurs in playback from the sequence after rendering has been done. If I play the clip in the viewer pane, directly from the list of imported files (without dragging it to the sequence first and rendering it), it looks fine.

    So something’s wrong in the sequence settings? The thing is, the sequence settings seem to be the same as my settings for the clip (422 LT with 30 fps and 1080).

  • I’m having a similar issue. I used MPEG Streamclip to convert footage shot on a Samsung Galaxy S3 and also on a GoPro. I converted it to ProRes 422 LT, and I set fps to 30 and checked “interlaced scaling”. After importing it to a sequence in FCP 7, it plays back with skipping frames, even after rendering. Would the interlacing probably be the issue? Or might it be due to how I set the frame rate?

  • Thanks to both of you for your clear and helpful replies. I never knew that FCP 7 didn’t work in H264, altho it’s true I’ve only used ProRes with it so far. I also didn’t know these things about iphone. I would think the two would be more compatible since they’re both Apple products. Is Filmic Pro something you’re supposed to download to the iphone or to the computer where you’re gonna do the editing?

  • The footage was shot on an iphone, H264 and 960 x 540 pixels. I custom set my capture settings and sequence settings to the same codec and pixel ratio so that I could put the footage into the timeline without having to render after. But I still had to render for some reason.
