View Full Version : Strange results ...

Hi there,

I switched on my C100 for the first time this morning, hooked it up to my Ninja-2, did the necessary menu adjustments so I can fire the Ninja-2 from the C100 and set about looking at picture quality.

C100 :
24 Mpbs
LCPM
50i

Ninja-2
1080i50
ProRes 422

I’ve shot a few slow(ish) pans and tilts but when the footage is slotted directly into FCP7 (checking that I choose the same settings as the clip), I have noticed that on these movements, the picture seems to be somewhat jittery. On solid lock-off shots, it’s fine (naturally), but the results on movements in FCP7 aren’t exactly satisfactory. I am not whipping it left and right, just a few slow gentle pans. The image on the Ninja-2 is perfect ...

If anyone has any ideas, then I would be grateful for any help.

Many thanks.

Are you getting these lines when you pan or tilt?

I have noticed something on my Ninja 2 as well, it has interlaced lines on moving shots.

Perhaps your editing program is interpreting the fields incorrectly?

I am getting these problems right out of the Ninja 2, ive been searching online about the problem but so far you're the only one who posted about this.

I noticed when the HDMI is plugged in too long i get these results, anything that moves have the interlaced lines on it, when i remove the the hdmi cable and plug it back in, it will record normally, if i keep it long then the lines would come back.

Stuart, it sounds like the problem may be with FCP7 and your mac not quite keeping up with the playback demands. The way to test this is to render a high-motion section to some low-bitrate codec in MOV and see if the motion now looks normal.

Or, it's possible that you're experiencing the same interlacing artifacts that James is. A couple of tests; render to progressive and review the clip very closely in fullscreen. Is the edge of moving objects jagged, only when it moves? This would be a deinterlacing problem. Also, try shooting some progressive footage in the C100/Ninja, how does it play in FCP?

Seth,

I’ll give that a go - I have nothing to loose!

In FCP I make a new sequence:

Custom 1920 x 1080
Square
None
25
ProRes 422

However, even when the project is saved, I take another look at the sequence settings and the aspect ratio has switched back to 1920x1080i ...

I’ll get back to you.

Thanks again,

Stuart
