Hi Everyone - this is strange (to me) - I shot video using my sony fs700 at 30fps - I imported the MTS files in Adobe Premiere > new Project - I checked the MTS file frame rate to be sure it was 30fps, made a new Sequence at 30fps, now everything matches. But.... when I play the video in Premiere I see "Repeating Frames" - each frame has been duplacted, I'm also playing back at 100% speed. I export at the correct settings & still Repeating Frames, any thoughts?

is every frame is repeating or just some?

Is it just on playback or also when you step through frame by frame?

/Are you sure you didn't shoot 30p over 60? This mode, if the camera supports it, will shoot 60fps but maintain 30p. It does this by repeating each frame. The end result is a 30p "look" while maintaining the 60fps spec. Upon playback, you wouldn't see the repeating frames. Only if you go frame by frame would you notice the duplicate frames.
Our tape-based DVCPROHD 720p Vericam shoots this way if we want to shoot 30fps.
You shot true 30fps, but your timeline is 60fps. So, the editor is duplicating frames to maintain 60fps. Again, unnoticeable unless you go frame by frame.

Your video could be fine! Your computer may not be able to play back HD photo-jpeg. I have anew macbook pro and photo-jpeg plays back glitchy on that! Like Ben said above open your video in some editing software or player and look at each frame. You may find that it's fine!

Hey Steve, I would give it a try at importing and rendering at 29,97, if it is one frame each few seconds, it might just be a compensation for a frame rate gap between recording, importing or rendering.
or is it every frames that repeats twice..

Thanks everyone! Yep, the frames are repeating everyframe....... on playback in Premiere before making ANY adjustments or even after exporting........ OrlowskiDesigns > thanks, i'll check this, I really do not remember what frame rate I shot, I "think" I shot at 30fps, I'm coming up with the 30fps by looking at the RAW specs in Premiere which tells me it was shot at 30fps. Spencer_Whalen > nope, not the computer, it is definitely dupe frames.
I'm going into the studio tomorrow & will try making a Sequence in 60fps & see if is shows up, thanks everyone!

The frames may still repeat on a 60fps timeline IF you shot 30p over 60. Meaning the CAMERA was recording duplicate frames--on purpose.
If this is the case, it really isn't a problem. Just make sure your output is set to 30p. The editor will then CHUCK every other frame to make a "true" 30p video clip.
If you shoot "true" 60fps, every frame would be unique. If you put a true 60fps clip on a 60fps timeline, you'll see each independent frame. If you put a true 60fps clip on a 30fps timeline, you'll see a 50% true slow motion clip.
