On the timeline I have a `PANNING`section of video produced by an iphone 7, as the video is panned to the right there is a `SHIMMERING` effect, this is only present on the panned video shot/s, can this be improved, I have Video Pro X14, any ideas?
@videomagic, Hi could you upload a sample using the arrow button next to the smiley on a new comment?
Hi.
Yes, if you could upload a video for us to see that would be helpful as we may have different ideas on what 'shimmering' means.
There are two main problems associated with panning as far as I have encountered.
The first is with the focus. If focus is set on auto it will hunt during the pan making everything soft and blurry. Better to set it to manual and refocus at the end of the pan if you have a 'tap to refocus' option.
The second is with the image stabilisation. Normally when dealing with anything that relies on electronic stabilization which will do it by cropping the available sensor area so the image can be moved electronically to compensate for uneven panning velocity. Either turn image stabilisation off and correct in post editing where the stabilisation plugins are on average more powerful with more options to correct it of get yourself a steadycam which will reduce this effect a lot once you learn how to use it effectively.
On the other hand it may be neither problem so a short video would be nice to analyse.

Hi
. . . . PANNING`section of video produced by an iPhone 7 . . . .
Pan shots with progressive video and a lower framerate eg 30 fps can be difficult to fix, especially if combine with a video source that is Variable Frame Rate and the pan speed.
To check if the iPhone video is Variable Frame Rate (VFR) - many mobile devices record VFR, download and install MediaInfo and analyse the iPhone video clip, see this tutorial on how to setup MediaInfo and analyse a video clip for all the data required.
In the Video section if you see this:
Framerate mode: Variable
Then try converting the video to Constant Frame Rate using a converter such as Handbrake or AviDemux. If you use AviDemux see this comment for how to do the conversion - the example is HEVC (h.265) to HEVC, if the iPhone video is AVC (h.264) then select the h.264 (MPEG 4 AVC x264) video output option.
Test the converted clip to see if this helps.
