As I speed up clips, gaps are formint between cuts that I cannot remove

As I am changing the speed of individual (100-3000 frames per second) video clips, gaps are forming between the cuts that I cannot get rid of. Even when I zoom in I am not able to drag the clips towards each other. That is only possible if I allow huge overlaps in the clips. I have seen a similar question on the forum (not related to clips being sped up), but no solution. I use Magix Movie Edit Pro 2014, windows 10.

Hi,

I don't have 2014 on my computer anymore, only 2016. I had no trouble dragging the right object to the left to close the gap. I did one at 10x speed.

Try switching to single-track (8) or multi-track mouse mode (7), then applying the speed effect. This should automatically close up the gap.

I believe this happens when you set a speed that is not a multiple or divisable of the original frame rate ie 25fps timeline set 20.46fps or some such. This is because MEP creates copies of some of the frames and they do not fit properly into the project frame grid.

VPX may handle this differently because it has a (audio) sample rate accuracy whereas MEP can only work to the nearest frame.

Hi,

I was trying this with MEP 2016 Premium. As soon as the speed increase is more than 4x, a message pops requesting to delete the audio. I accepted. If you cancel, it applies 4x. No problem. I'm using 29.97fps and I typed 10x into the box, thus 2997fps. I tried 11x as well. Both dragging the objects and using the mouse mode (8) worked fine.

It may be that there is a problem in MEP2014.

@lenef - did you update to the latest patch?

Make sure that there is nothing on the other track or in the gaps on the track that you are using. I recall having a problem moving objects because there was a tiny artifact left on the track and somehow it blocked me.

Hi John

I have seen the same behaviour in 2016 as 2014. It seems to occur when the slider is moved to where it creates a fractional framerate in the fps box and this frame rate does not equate to a mathmatical multiplication of the factor x the project fps eg. 1.13 x 25fps shows 28.21fps but is actually 28.25fps, or 0.78 x 25 = 19.75fps but actually is 19.5.

This may be a rounding error which is not displayed in the factor box being only visible to 2 decimal places but I feel it is more random.

The standard frame rates of 29.97, etc. do not appear to be affected or have been corrected to behave correctly.

I have seen this in earlier versions of MEP also and I usually just adjust the slider slightly until the end of the clip just falls on the frame marker at the top of the timeline.
