Gefilmt mit Mini-DV , Ton von Laptop: Asynchron, weil ungleiche Länge

Filmed with mini-DV, Sound of laptop: Asynchronous, because unequal length



Frage von djoesch:
Juni 2008

Hello,

have here a friend of mini-DV tapes and a WAV from the mixer and get to the cutter join.

During mastering of the two audio tracks, I noticed
WAV of the mixer suddenly the synchronicity of the AVI audio track adopted, since it is so easy gestretcht lightest overall slower than the WAV.

Did with the bitrate to be done? Weiß da jemand was?

The WAV is 1411 kbit / s, 16Bit, 44kHz, PCM
The AVI is 1537 kbit / s, 16-bit?, PCM

If the reason is, how can I change the bitrate of WAV on 1537 exactly push?

Liebe Grüße,
Daniel

For MiniDV recordings, the sampling rate at 32 kHz (12 bit) or 48 kHz (16 bit) lie. This difference is, as a result of the data has influence, but synonymous for the duration difference is responsible.

The same WAV Recording with 44 (, 1?) KHz s.Dein first video project, before you know it into the editing program importierst. With an audio editor to convert the sampling rate is not a problem.

It remains only finally to be hoped that the audio recording in principle to fit video and not before a run-time difference poses. Depending on the audio recorder is synonymous might be the case.



Antwort von djoesch:

Hello and thank you for the hint.

Did the AVI (48 KHz) and left the WAV (41 kHz) to 48 hochkonvertiert.
Unfortunately, nothing.
I mean synonymous to know that Adobe Premiere Pro CS3 auto when imported into the project sample rate converted.

Something is foul.

I'm trying now s.Ende audio track from the external audio track by time-of s.den AVI align.

But why does it ever came to the problem, I still do not.

Greeting





Antwort von Schlafsack:

No component has the same values, it is always subject to a certain tolerance. Therefore, synonymous with the recorder is not exactly the same frequency. And so the recordings are always somewhat apart. Times more, sometimes less. And if that's not the case - lucky.
There are devices that are hardware with a synchronous signal can be synchronized. That is the only way to be sure to co-shots (Picture as sound) to get.



Antwort von djoesch:

Then time-the last chance, right? Because now it's too late anyway.

Grüßle



Antwort von thos-berlin:

I had the Problm synonymous ever, with 44.1 when I recorded the sound was. I then scratch with Time adjusted the length (three-pronged approach to calculate the gain should be known). The result was totally OK.

Since I got the sound recorded at 48 KHz, I have no sync problems noticed (or just lucky).

...... What are you doing since forever? Why take the sound with just the net on your camcorder? What does this always with the external fixation .....

DV is now not Timecodefähig ..... it is internal clocked .....#

There are devices that can save it - have to play via SDI DigiBeta ne Maz (or DVC PRO 50) and synchronize with the studio clock or TimeBaseCorrector etc. new. (which then goes into the car at the capture NLE)

synonymous, but only as long as you do not have Music Video with 44.1 or 96 or even 192 kHz must produce ...... ;-))))))

ProTools offers solutions as synonymous.

If only the audio mix in the studio is to be made, you need the sound of each microphone separately. And when an orchestra is far more than just two. ;-)

Another argument you deliver in the previous posting, because hochsamplen is synonymous not so great.



Antwort von videobob:

@ Markus

We should have a thread here on the SMPTE, VTC, LTC, wordclock, Midi, VITC, RecRun, FreeRun, and similar UserBit make .... ;-))))))

Yes and where is the problem?

You should stop on a camera with time code and an interface depends on the sound in between (Motu 828, or ProTools .....)

But without external clocked Camera is in the mail always a problem.

The Motu Mk2 can even sync via firewire .....

And with a DV Cam an orchestra with 48 tracks record, it's like Formula 1 with the VW Beetle ...... dat tut net .....

Many people simply appreciate the possibilities and have problems later. That's why there are so prof.Kameras and truck ;-))))))

But the questioner said already that he is the sum of the mixer has gotten .... why not the sum in the camcorder? From me from over radio link ne ????????

Otherwise (in single track recording) would work quite nicely - and then let it either or I'm so smart, I am here in the forum are no further questions must ..... Because the knowledge of sample rates, I vorraus times - for such a project. (Not to be confused with time differences, this is something completely different and kick at a concert with Orhester s.15m on ...... ;-)

The comparison limps a little, because at a concert, the sound so the same, if not more important than the Picture. And since I see no problems, the picture only in DVCAM (not DV-Cam) and incorporated the sound into (better) quality of them. From Synchronitätsproblemen although I read here again and again, but had not yet even the problem. You have to do is everything with the same sampling rate and run audio recorder for 50 ¬'s course may not be synonymous.

... interesting!

Does it really (I am referring to the FW port on the Camera image output and Tonsynchronisation use)?
Or do we need as a Time Code s.der Camera Connector (see hierAV-PC TS)?
I speak here of recordings on the PC.

Therefore, good sound engineer, there are now many reasons:
- The camcorder may have no manual Tonaussteuerung
- Camcorders and mixer are spatially separated
- For me the most relevant reason - you will not only record 2 tracks, but perhaps 10 or 12 and behind the sound mix.

I know the problem, both at 44.1 as synonymous at 48 khz and at various recording devices. Several camcorder you'll always synchronously, camcorders and sound cards almost never. The Timestrechtching of tone, however, is not synonymous bigger problem. In the premiere works wonderfully, and synonymous with no audible loss of quality.



Antwort von videobob:

But everything helps bellyaching so now the questioner nix.

He has now clocked 2 is not recorded with different sampling rates.

So emphehle I esrt times the adjustment of the audio material to 48khz.

And that in a good editor (ProTools, Steinberg or similar).

Then again export as. Wav and to the timeline set ..... the rest in carefully with fine-tuning and listening.

?????? 10 or 12 tracks?

The questioners talked but of sum signal of a mixer!
(1 wav / stereo = 2 tracks)

Let me guess ...... The asker has released filmed and has thought he is the sum signal to the laptop on, so he needs no cable stretch? Stimmts ??????

Then it better in the future funk track!

From multi-track production, he has NEVER spoken ......

But I have strange .... here is happy to talk to each other ..... ;-)))

I am the Meggen, not Mark.
If the questioner is now but a camcorder with no audio input or audio without manual control, which makes it then?
That apart, only the sum stereo mixer without Atmo rarely suitable for Endmix.



Antwort von videobob:

Meggen Sorry, sorry Mark ...... I had time code problems ;-))))

If it should be, then the questioner should not filming concerts .... lol ......

If I were a car without fuel and had wheels, I ask but not synonymous, as I so of Berlin to Hamburg komme ... or?

Hello,

Here was a concrete and perfectly serious question. I think not synonymous, that the approach of the Asker's fundamentally wrong, whether it is a stereo recording or Mehrspruraufnahme made.

They certainly do not, if its no Camera (right) audio - In should have - What we do not know and what is actually synonymous is absolutely no preference, then was not asked.

That is, mutatis mutandis, be advised that such Aufnmahmen not to do, then that is completely out of my sight and also helps synonymous not really next. Would the answer be different if the sound engineer afterwards had said "Hey, I have a CD for you, perhaps, you can use to for your video?" ?

I have made my top tip. I think the software is Audacity, and it was for my amateur purposes - synonymous Musikaufnhame - quite enough)

I have my top tip synonymous and would have him even for ProTools ne lend weeks !!!!!!

Sodele ....... Recht haste!

But it is precisely in forums .... there are / and should) debate stimulated.

And it emphielt then just read everything ... synonymous for the questioner!
