Video FPS

[realspeed]

My camcorder Panasonic HC-X900m records at 50fps which is perfectly acceptable for most shoots except for straight panning. The FPS at 50 is far too slow to create a smooth shoot . Video to follow when downloaded, when on full screen you can see the "jerking" as it pans around my cattery.

However My Nikon D800 will shoot at 60fps which does produce a smooth panning shoot, that extra 10fps makes all the difference.

So if I may suggest when buying a camera/camcorder do make sure of the frame rate it records at. My guess is that this is something often overlooked

That is nonsense

The jerking you are referring to is called "strobing" and it's a result of panning too fast. FYI film cameras have been shooting at 24fps for years and they manage just fine, it's your technique that needs improving.

its not a case of panning too fast it just can't cope. Watch in full screen mode and you will see what I mean. not my panning but the juddering very fast I am on about. Oh and the camcorder gives out a message if panning too fast anyway

I don't get that with my Nikon D800 at 60fps

Try reading this.

unfortunately that does not apply to my camcorder but to something else entirely and also is for fixed mm length not variable.
As you must live near me maybe you could visit and give some help and advice

See PM

It proves the point that panning speed has an effect on the juddering you are seeing in your video. Unless you can find the relevant panning speed tables online you are just going to have to do your own research. I doubt the ASC Cinematography manual (which has panning speed tables) covers a consumer camcorders like yours.

At the end of the day I'm telling you the answer to the problem, if you don't want to accept that, it's up to you.

What shutter speed are you using? It looks like that isn't a 50% shutter and that there's some sort of image stabilisation kicking in.

The difference between 50 and 59..94 is minimal in terms of panning.

Unfortunately the camcorder in video mode can't be altered, only when taking stills can the shutter speed be altered from 1/50 to 1/8000

I'd say looking at that video:

1) there seems to be an image stabliser that "catches" as you pan.
2) the 60fps shutter speed is nearer to 50% than the 50 fps.

Neither of which prove your assertion that 60 is better than 50 at panning.

In fact you'd need 100+ to get fully smooth motion on what your eye is tracking and significantly higher for everything to be smooth.
