Jerky Video

Hi

Video filmed on my iPhone 5s is really jerky when panning after producing the final video. Its fine on the phone.

I'm producing mp4 1280x720 9000 25 fps to play on Apple TV 3.

I've tried 30fps (NSTC) and 1920x1080 but still jerky, most noticeably when panning.

Any ideas please?

Thanks

Are you judging the video by Powerdirector's Preview?

If so you are getting a false indication, The Preview in Powerdirector is dependent on your computer's CPU and your Video Card and the Preview Setting.

The only true test is to Produce the video and play in an external player.

Hi Carl

No its the produced video that's Jerky.
I'll upload a few samples tomorrow.

In that case please post your computer's diagnostic.

Hi Carl

I've been doing some testing and its the frame rate which is causing the problem. I based my custom setting on the device preset for iPad which is 25fps. When I change it to 30fps the jerkiness stops.

I normally have my project set to 25fps. Does it make any difference what the project setting is? It looks as though the produce setting overrides it, although there is a minor difference in the bitrate and data rate - but both seem to play ok.

I have these complications because I take video on the iPhone 5s (30fps) and also on a Sony camcorder (25fps) so its hard to find the best settings for Apple TV3 for videos made up from clips from both devices.

My life is too complicated

Thanks again

I would use the 30 fps since that works best with your iPhone.

It is easier to add frames than it is to remove frames.

With 25 fps PD has to add 5 dup frames to make up the difference, PD does a better job of adding frames than it does in removing frames.


It does make a difference. The main difference is when you make DVDs, in some countries, the DVD players will not play the wrong frame rate (for the country) DVD.

Many low priced DVD players in the USA will not play a PAL DVD.

Anyway, use what works best for you.
