Jumping on speeded up panning shots ?
Hi guys

Just a quick question. I have a few panning shots (wide establishers). They are a touch slow for the edit so I've speeded up to 115%! I have horrible jumping in the resulting output! - I have noticed this before but to lesser levels. Can anyone suggest anything ?

Many thanks

Mat... you may find a solution with the Field Options (right-click your clip) for the target clip.

If I remember right, I have achieved smooth motion with varied speeds by "interlacing consecutive frames".

Also try turning Frame Blending off (right click clip and de-select)and render a preview to see if it works better.

Your faster playback speed might need a slight cut to the source clip so that it totals a clean multiple of the final number of frames you want to play back for the speeded up version.

Otherwise the software is going to have to do some frame-blending here and there which is where the hiccups will occur.

Hi guys

Yeah I did wonder about making it a 'safe' increase in the amount speeded up. But you'd think the software would be intelligent enough to regulate this! - Its not a frame blending issue.

Has anyone else had this sort of issue before ? - This one has been particularly bad but I've had it more mildly before.

Its 25p 720 footage - mpeg1 - jvc gy hd110

"But you'd think the software would be intelligent enough to regulate this!"

Western societies are freedom loving people. Just imagine if the software writers put up tiles which declared - "you cannot do this - return to GO" or "you will obey - return to GO and do what the manual tells you".

It would be a little more honest if they did. There would not be rioting consumers and blood on the streets but the software might not sell so well anymore.

Marketing of a product is based on declaring what it can do, not what it can't. I don't envy them as they try to navigate that fine ethical line, assuming they bother.

Maybe that is why some people ramp the framerate when applying a speed-up effect. Would that tend to cover fractional cadence artifacts?

Hopefully somebody who knows will tell soon. Please do not ascribe my comments as having any qualification. I am short sighted, partly colourblind and failed maths from grade 5 onwards, so in this instance I am particularly unqualified.
