Hello Forum
I have a problem with my XH-A1. I have a plane flying past (see the jpg attached) filmed with the following settings:
Mode: 25f HDV
Custom preset 1 (This is of presets Wolfgang)
AGC: OFF
AWB: ON
Gain-3dB
Shutter 1 / 50
Aperture: 3.4
Built in ND: 1 / 32
Tape: TDK DVM60
As in the Picture to see I have some frames in a sort of "ghosting" effect. My question is, where is that? If the s.25f mode combined with 1 / 50 shutter? What must I do to get rid of this effect?
I'm thankful for every tip.
Thank you for your efforts in advance.
Gruss

This looks to me more like 1 / 8 or 1 / 10 second after the shutter from 1 / 50, how else should the images, the frames 1 and 2 include it here with decreasing transparency be seen? The lack of sharpness also explains the fact.

Synonymous, I would say take Shutterspeed higher for fast movements.

In the above recording, I had 1 / 50 set. I have in the meantime, further tests done:
Motive: I before the camera with a hand wave.
1. Passage
Mode: 50i
Shutterspeeds: 1 / 100, 1 / 50, 1 / 25
Recording to: MiniDV tape
2. Passage
Mode: 25f
Shutterspeeds: 1 / 100, 1 / 50, 1 / 25
Recording to: MiniDV tape
3. Passage
Mode: 25f
Shutterspeeds: 1 / 100, 1 / 50, 1 / 25
Recording at: Adobe OnLocation via Firewire
4. Passage
Mode: 50i
Shutterspeeds: 1 / 100, 1 / 50, 1 / 25
Recording at: Adobe OnLocation via Firewire
Conclusion:
Between recording on tape and on location I can detect no difference. For my problem, it is not synonymous with the role if I 25f or 50i record, in both cases, I have this "ghosting" effects such as aircraft.
With a shutter of 1 / 100, I have up to 3 "Ghost Hands" in the Picture if I winke. For 1 / 50 is still only s.1/25 verschmieret the movement so I just had a long tail.
Could it be that my XH-A1 has a defect?

Now I have another test done and rausgefunden that the Nachzieheffekt exclusively with Noise Reduction of inter-related. The presets of Wolfgang are preset at the 2 and 3, the NR1 set on low. Once I set this value to set off, I have no "ghosting" effect more in the Picture.
If someone synonymous a XH-A1 has and with the presets of Wolfgnag (http://www.fxsupport.de/02_Canon_XH_A1.html#presets) works, it would be nice if you could confirm my observations.
