Please Help, I have video interference problems!!

Message  MiguelDeServantes le Ven 25 Déc - 23:52

I see this video interference lines on my video "Only visible on the video recording" When looking through my video goggles this lines are not visible, Can any one help?? I will post the two videos the original and the edited one!

                                               
On the Un-edited video the flight starts at about 4:30, and the video head tracking only starts until the 6:00 minute
For your help I will be very grateful.

It don't begins immediatly Neutral Could it be something that becomes warm?
Did you tryed at home, taking the time to see if everything is all right after some minutes? ( be carefull, the V.transmitter can get hot, don't let it too much).
A wire that moves when the camera turns?
You have not he problem with the googles?
If you could see the problem in your garage, you could try separate feedins on several battery, test with screen in place of the DVR, see if some devices are too close of each other...
Not easy to say at 8000km distance   Laughing

I leave this morning for a week with my family, and I don't know if I'll can see the forum during this time.
Hope you'll find a solution, I'm sure I'll read it in some days.
... and thank you to make me practise my english at eight in the morning the day after Christmas  drunken   lol!

Don't give up, Miguel, you're on the good way ! cheers

Fred

HI Miguel
I had a similar problem and it was the voltage regulator that caused the interference. I replaced the regulator and the problem disappeared.

And if you want I can make your practice your Latin "Castillian!! Yon no tengo problemas hablandote en español pirat But never the less I'm very grateful for your input, I didn't though about the heating problem! I have a bunk bed rack that holds two power supply systems, one is a 12v and the other is a 5.5v, you know what they are for.. and it does actually get very hot! Even do I did make it seat on top of a very small heat sink!! but you definitely have a very valid point!!

Serious improvement "Not perfect but serious improvement"

Message  MiguelDeServantes le Dim 27 Déc - 6:18

Looking on to the videos of electronic components... "MORE SPECIFICALLY BUST CONVERTERS" I learn that must of the devices that provide power to must electronics "Like the Step Down DC to DC Converters" are ridiculously noisy.. yeah! I did knew that my problem was noise.. but sellers always say that their products are good quality and the least possible amount of noise!! "Yeah right!! never the less here is the video showing the improvement...

Message  MiguelDeServantes le Lun 28 Déc - 1:26

the lines still there! In the minute number 4 one can see the lines starting to get more visible. ATTN THIS VIDEO IS REALLY LONG! I was testing the theory from Fred.. that mentioned that may be something is getting really hot and thus the interference was some what from that venue!

I'm terrybly sorry to have to say that my success was short lived!

Message  MiguelDeServantes le Sam 2 Jan - 18:07

I have to say that the lines have almost totally gone away!! but sadly the constant interference "Choppy video interference every 5 to 10 seconds still there! I honestly don't know what to do... I have changed channels, put Video LC Filter, I even cover wiring and components, with a aluminum foil so it ground all types of isolation... but the stupid constant interference that cut the video still there! is so frustrating!!

Any way thank you very much for all your help!!

There are some lucky men who are immediately successful, (and they don't know how) but for others it's a long way ( but they learn a lot Wink  )

It makes me think about something that happens to me sometimes. Sometimes, each time on the same two spots, I hear a beep each five or ten seconds, while the image has a hiccup. The first times I was affraid because I thought the video was about to fail, but it never stopped to work. In fact, I think it has nothing to do with the plane and its equipment. I suppose it comes from some radio passionate or something.

Yes, I actually agree with you, I have just to much radio Equipment around me!

Message  MiguelDeServantes le Dim 3 Jan - 1:55

But perhaps the most demoralizing aspect of this is that every one is using the same type of frequencies that I have to work with!! No
