Infoseite // Is linear Assembleschnitt interference possible in HDV?



Frage von r.p.television:


Hello.

Have a big problem and until now I can not answer technical support of SONY Professional or other this question, although they at first appear is not that complicated.
It seems that I am one of the very few who takes the job, working copies of the HDV tapes to want to create. Sense of the thing is useless material in the run auszuselektieren to shorten the batches or to reduce the filing costs.
Since the HDV data code (the one for the batches or the scene needs some separation now lost) on the PC interface is (at the latest edition of the band), I wanted to make a linear Assembleschnitt. Also of my Canon XL-H1 camcorder into my new Sony HVR-M25E HDV Recorder. With each cut made by the recorder from a disturbance occurs, looks like the following:

Picture the scene preceding remains standing (for about 1 seconds) and only then will follow) the incision into the new scene (without disturbance. When single transport through the interface shows that there are several Leerframes. The Leerframes probably cause the picture hanger.

A change in the drive settings, I have not found.
The error occurs even synonymous to when I found during the recording of HDV via Firewire rehearsed the material is fed without interruption, just press the pause button.
I then tried the cut in the opposite direction, from the recorder to your camcorder, and this was exactly the same problem.

Hence my question:

Who has already had the same problem?
Or there is someone who copied straight without any problems and has made cuts without dropouts or gaps?
If Assembleschnitt trouble at all possible (when recording in the camera when scene transition are indeed synonymous interference will not - so why here?)
There may be a known hardware conflict between Sony and Canon, which triggers this problem?
Is it the GOP structure of MPEG-2 streams to blame?

Would be very grateful!!

Liebe Grüße, Mike

It should usually 15 frames to 29 images to be delayed. Comes of the GOP structure of 15 images. How to handle the new volume on hard Renderei cut.

I understand the concept with the corresponding GOP is to blame. Once had when editing transitions at the output to Divx problems. Somewhere, the video stream goes to the "conversion / transmission loss" or something is not correctly implemented by the codec.

What program you are working. (For me it was time AP6.5.)

That make sense to me synonymous. I ask myself but why during the actual recording camera (when I hit the synonymous of hand a few times a scene in order of there weiterzufilmen) these problems never occurred? And I'm talking about 10 hours of wacky materials, both Sonyals synonymous with the Z1 of the H1 of Canon. I had not a single dropout or artifact formation, but now hard at each subsequent tape cut.
Have gepennt the Manufacturer? It must be possible to cost around 14000 Euro devices together, undisturbed. Making pure strip cut, without disruptions occur, we are of software or Drittgeräteherstellern like Firestore etc usual.

If I have misunderstood you then that is not a malfunction, but a systemic discomfort, with which we must live?

Hello. Also thank you for your quick reply, but my problem never covered the software I cut (by the way working with Premiere 2.0), but purely for the hard cut of camcorder tape recorder to create batchbare archive tapes on which a complete data code is present (data code is being deleted even if you back out of the calculator is on tape - or anyone here knows a solution or a simple cutting tool in which this problem can be avoided?)

When editing with Premiere 2.0, I never had the slightest problem with missing frames or interference.
I would like to stop as it used to IR - or-DCCam times my batchbaren, shortened (without unnecessary shots) archive tapes with data intact Code ......
