More Video in the Round - Judder Solved

First a couple of videos made at the end of my lane just past the Village Cricket Field:



Even though I glued a small bubble level on the wooden base I find it is still quite difficult to get the horizon level. As the camera mounting allows me to tilt the camera it really needs a level on the camera but the small Nikon doesn't have anywhere to mount one.

As my old school reports probably said on many occasions - room for improvement.

I found a couple of different, cheap, 12v slow motion motors advertised so I will experiment with those when they arrive. They are 3 rpm so should take 20 seconds to take a 360 panorama video if my maths is correct. One arrived this a.m. (less than 24hrs after putting in the order).

A happy hour in the workshop making a simple mount for it.
A piece of plywood, the motor and a switch:
P1040538

P1040541

First I tried the Nikon at its usual 30fps - still a bit jerky.
Inspiration, try 60 fps. Brilliant on two counts. With the motor turning at 3 rpm it was a bit fast but iMovie plays the video back at 30 fps which seems to turn out just fine.

A quick test in the back garden;

I know - the grass need cutting .... again!

Part of any perceived jerkiness is caused by the software which shows the video. On the Mac it is just about perfect when I use the free VLC  player

Now looking for a suitable 12V power supply which is pocket size. There are some small NM-HI types for drones etc. but as yet haven't found a suitable charger for them.

  2. The colour grading in the first video at 43" is perfect.
    The second video is much better. Now it looks as if it's time to mow the lawn.

    1. Roy. The Nikon is very good, especially considering the price of them.
