Infoseite // HDV picture errors / dropout??



Frage von Der O.:


Hello,

had made the day for the first time a few test shots with my FX1 in HDV and had to find something very ugly here.

And although aberrations after capturing with Premiere Pro 1.5.1 or HDVsplit0.75. Several times always repeated again s.der same place. 2 examples of many, unfortunately, I have added.

In the frame on the tape, I see no errors, synonymous with the camera when I of HDV -> DV gibts walk no visible errors.
I have the beginning of s.with Sony DV Excellence tape rotated.

Is this a dreaded dropout, or an MPEG2 compression error?

Many greetings,
of O.

Antwort von grovel:

Hmm
Although I had often dropouts in HDV, but so far has a repeated capture with HDVSplit still always helped. (Try again, two times, three times)

Without letting any test character now, I always used Sony Digital Master Tapes (19 ¬ / 29Sfr the piece) and had to drop any tape (but as I said, no final, repeated capturing still helped more). Only once did a cheap TDK MiniDV tape filled, because I could find no other s.Sonntag and tataa * * - not a single dropout. But since all the tests say that one should rely on the Professional series, I'll stop next with them.

So I changed views movies with next 2.1 Euro Fuji tapes - sometimes to see if the dreaded drop outs so I can ask for or not.

Antwort von Der O.:

But the cause for now a dropout, because until now I only know of the "analog", "Digital" I have not seen before. Or this may be an intermittent compression recording error, or halt "just" a Übertragunsfehler when capturing (just curious, as always s.der same place)? For a dropout would help so synonymous not capturing repeated, since the error is indeed on the tape and the error would apply not only to a frame, right? In addition, one must still synonymous Downkonvertieren of HDV -> DV with the camera to show the dropout, which is not even doing.

What do you think?

Antwort von wolfgang:

So as I understand, drop outs, especially in I-frames, especially in HDV2 lead to a loss of 12 frames. So this is not time, otherwise you should have no picture.

So could a drop out at a different frame his type, but how can you prove it, I do not know exactly. The same blockage occurs even at synonymous among the people in the Picture. To clear blockages we actually know of mpeg-Kompressioenn synonymous, but in this form, I have not seen in HDV2 (although the material with a relatively low data rates especially for single analysis, of course, is prone to compression errors, artifacts found so synonymous in DV-avi if one is only looking for).

Hello Wolfgang,

You have you looked 1.jpg synonymous times HDV Error in large? There are not only blockages, but colorful blocks tangled in it.

VG,

Antwort von wolfgang:

No, I did not confess, I have to. But this looks rather bad, because I ask myself more, obs because some hardware fault. They are unlikely to dropouts.

And since you the error even when direct playback of material from the FX1 (via component to an HD-ready screen?) Did not, I would look for the cause of more times in the PC.

Antwort von grovel:

But, as I saw HDV-dropouts from synonymous. But it was with me as I have said no problem.

Antwort von Bruno Peter:

They are still blockages, a sign of lack of performance in HDV!

Antwort von wolfgang:

Grovel, are you speaking of 2 Picture? Also sowas I had not yet dopout as - so far.

Antwort von Der O.:

@ Peter
What do you mean with lack of performance with HDV? In Kompriemierung during the recording? Or when capturing, but this can be actually already ruled out again. Since I first repeated several times, and capturing the error occurs always s.dergleichen place and secondly, the calculator actually is fast enough (Athlon X2 3800 +).

Does that indicate that something out of a camera hardware failure??

Quote: Does that indicate that something out of a camera hardware failure??

Nee how "you've got this error is not in the preview on the camera display. Consequently, it must be s.der performance during capture. Perhaps there will be a re-calibration or performance drop in hard drive during capture. I would simply times the critical piece to another hard drive to capture fault isolation or capture even at a friend's piece.
