Frage von slyber:
Hello,
I've been working for some time s.einem compilation of a school festival.
The sound was recorded with an external Micro a camera.
The film is finished (cut in Premiere) and the menu etc create () in Encore.
The problem: The finished DVD created approximately every 2nd DVD player an interfering signal, but only the place s.genau starts s.der the sound of the external microphone. But if we (if possible) one of the two audio plugs from the television, the signal is back to normal, no preference which of the two I prefer.
That's just odd that the sound properly on some players and the PC works.
I have several mpeg2 codecs dv-and-tested, and I also tried the first soundtrack to convert into other formats, synonymous of 48,000 to 44100Hz, etc. .. So far nothing has worked.
Please help me, I must necessarily solve the problem!
Ever Thanks in advance.

Hello,
the description of a "false signal" I find very general. Like this manifest itself? Hum? Noise? Quitschen? Clipping? ...?
If you feel here in the forum as a user logging in, you could be your next post is an MP3 file (zip-compressed) with the relevant noise attach.
First idea:
Antwort von slyber:
Thank you ever taken out the answer.
So the sound is as follows: The original sound is very quiet and somewhat distorted to hear about a hollow sound is extremely distorted, especially when that clap loud tones (, basses) occurs. Otherwise, everything sounds tinny together.

times quite stupid meant ....
If you already have tried different players, you've already tried different cables synonymous?
If I understand correctly, you have the noise only when you have both audio cable plugged in? You pull one out, it's gone?
Then everything would make no sense any other.
Is the the original audio recording in mono or stereo had been taken?

Antwort von slyber:
On the cables can not lie, each player has a different one.
The original sound is recorded in stereo, but I tried synonymous, all converted into mono
-> Synonymous is useless
Other codecs (mpeg2, dolby, pcm) get nothing.

Antwort von Markus:
Hmmm, that's a tricky thing. What can be said for an outsider to say, neither your DVD (the sound on it) nor the various player / TV Combinations knows?
If the phenomenon may only s.Mono-on TVs? In this case, the sound would simply not mono-compatible.

synonymous, it would have to see the spot yet to invent a solution to ...

I suspect something else.
The sound is OK not s.einigen players s.anderen.
For me, after listening to the "hum loop". Just because the sound is s.diesen players after removing a cable (channel) OK.

Hello!
It sounds to me like a phase problem. Is disturbed by the sound from surround systems ok and when playing through mono-TV?
Proposal. Test editing program in the way the signal from the external microphone in mono convert summarized (channels or take only one channel) - must be tested. Better part of a clear monotone distorted as a stereo sound.
Greeting!

Antwort von slyber:
So I've already tried the sound from the dvd player via headphones to hear, so no TV, same problem.
At Ground loop occurs to me was: I once had a mixer s.das I went with the wrong cables. Noise or hum was always when I had plugged in both cables, with a focused (which is not previously occurred to me ..).
I can not remember exactly s.The cable, but perhaps the signal is transmitted twice or something? (only how to prevent this)
I have been synonymous tries to convert sound into mono, synonymous with no success ...
Again, many thanks for all the advice!

This can occur even if a DVD player has no real grounding, but is encapsulated only electrically.
If it is, only helps the device ground subsequently.
In any case I've seen parts already sone, which only have a 2 pin Netztanschluß) (as so'n electronic razor, then definitely there is no earth turn. If you now the DVD player s.den Television stopper (which is grounded) You may have a problem. Certainly possible, then there's ne hi dranhängt plant.
Warun the other hand only occurs when the body which comes with an external Micro was recorded ?????
Antwort von Markus:
This can occur even if a DVD player has no real grounding, but is encapsulated only electrically. I just had time to think, what power supply had the DVD player, which I have in my circle of friends and acquaintances joined in recent months. - They were all equipped with Euro plugs, None with safety plug.
In the above case, it may help to reverse phase and neutral to (read: pull the plug to rotate 180 degrees and back into the socket) is stuck. This allows to eliminate ground loops often. ;-)
Antwort von steveb:
So let's take one together now.
You have made a DVD that has made on various DVD players, televisions s.verschiedenen sound problems.
I klnn me with the best will not imagine that s.verschiedenen systems, there is always a grounding problem. They ought to be synonymous with other DVD's give a problem.
I think it only helps to marginalize Logical.
DVD (the first system of TV and player). Grumbled, then try out the next player and TV. When a system trouble is it to check what are the differences. I guess there is some kind of logical, small problem.
hold us up to date.
Antwort von slyber:
Sooooo ...
Thank you for all your advice!
The solution of the problem () by constant trial and error: remove a channel, turn the other back in mono. Pointless but it works (even ordinary mono because nothing brings out both channels) ...
Well thank you, and you're all just really great and so.
