Bild bei Festplatten Cams nach nacharbeiten so schlecht ?

Picture Cams after hard at work after so bad?



Frage von Kolben:
September 2007

Hi,
have before me the SonyHandycam DCR-SR290E to fetch.
The Cam is a 40-GB hard drive, MPEG2-PS to.

MPEG2-PS is a special format?

What is it with the post from s.PC?

If I were with HQ (9 Mbps) films but it should suffice for finishing?
Are there really so much loss of quality as I always do, or are the programs for the post now, the better the quality loss is less?

Antwort von rootfire:

Hi, I have a SR1 and the recording in SD is ok. In my opinion, there is little difference in the result of the processed material to the original. Would say almost on a standard television tube also with with about 76 cm image area you can see no difference.

The question is, what you're a filmmaker? Times I go out of Hobby. And for these claims should be the quality is totally fine.

MPEG2-PS is a program stream. Which of Picture and Sound in MPEG2 compression is composed. There is no special file format and should be easily into any editing program can capture.

Therefore, the rework is not problematic and should be based on a normal calculator with about 3 Ghz Pentium 4 with 512MB RAM can do well.

If you do not need to rework the files should be synonymous in any DVD authoring program can capture.

You hope to have helped little.

Greeting

Christian

Hello,

the problem is more fundamental nature:

MPEG2 is a highly compressed format, where not only within the individual, but also synonymous bild across (that is the subject of movement in the Picture) is compressed.

If a processing takes place, so you may change the image content or image sequence and thus the basics on which the film material is compressed in the camcorder.

For this reason you should ideally act as a MPEG2 "format", ie in a high-quality, low-compressed format (like DV-AVI) and absorb all the editing, then compress to MPEG and of this final moment s.das only unchanged use and otherwise steer clear of it.

Gruß,
Markus
