Frage von Preibi:
I have a Panasonic NV-GS 140th The home movies I'd like to burn to DVD. The quality of produced DVD is much worse than my AVI file. The whole I have tried with Magix Video Deluxe 2006, and with the supplied Panasonic software. Has anyone a hint how I can create a DVD with no loss
Thank you in advance for the help
Antwort von Hogar:
Without loss, it does not gehts. But you can minimize the loss, he is practically invisible. Perhaps time to try another encoder, such as ProCoder or TMpegEnc. The MPEG2 files created with it then you have to put a DVD together. Da gibts a variety of programs. TMpegEnc is synonymous DVD authoring software, which is sufficient for small needs.
On the other hand you can go the erstmal try to increase the data rate on your current encoder (Magix software or Panasonic?) Or to change other settings, so that you have the full Resolutionund correct field order, etc. .. The DVD issue is quite extensive, so I now write erstmal not to because of your lack of synonymous accurate information.
Good luck

to nreinen theory:
The mini DV tape takes about 13 GB storage for 1h. The DVD had net 4,3 Gb space. so now you can well imagine how much more must be compressed on the DVD!
The integrated DVD authoring software in editing programs here are not particularly suitable. Bit rate when Brenne where superscript as moderate
OSSIBLE, as it was already written. In the hardware of DVD recorders 1:1 DV tape recorder to play and burn it. In trying to Nero 7.0.
The best quality is and remains the Mini DV tape, it must be clear.

As one in the DV format only I-frames have to be able to properly cut, the one in the DVD format does not need, you can with P-and B-frames to achieve a higher compression with very little loss of quality. I think DV with 25 Mbit / s in the consideration to be equivalent with a with ProCoder Express to 9 Mbps compressed DVD.

I presume you mean the right, but slightly askew from express yourself ....
DV format, each frame make a full-resolution frame. Data rate of 25Mbit / s. I-frames, there is not in DV. Neither P-or B-frames.
MPEG2 (for DVDs stipulated Komperssionsformat) is working with I-, B-and P-frames. These different frames in GOP (group of pictures) together. I-frame is a full-resolution picture, which shows P-and B-frames only changes to the image to the I-frame or the previous P-and B-frames. A GOP usually consists of 12 frames. The first frame in a GOP is the I-frame. But it results in a cumbersome synonymous cutting the video data, since only every 12th picture is a full-resolution. Cutting in MPEG2 is unwieldy. Cutting in IT responsible for a complete joy.
From these results then GOP synonymous of lower memory requirements for MPEG2 compressed files. 9Mbit / s data rate may indeed have achieved the top upper limit, since a maximum of only 9.5 or 9.8 Mbit / s are permitted, according to DVD Spec. And the sound is there already included. If you are enough with 8 Mbit / s compress the normally loose from a top-notch DVD-Picture, which have only in difficult, ie, fast video sequences compression artifacts could.
So for the quality of a DVD into MPEG2 compressed video is always worse than the original DV AVI band, but if it was done well, is the difference with the naked eye can not detect.

but if it was done well, is the difference with the naked eye can not detect. And that's what matters in the DVD, yes. They stop is (the end of the processing chain, however, who says he wants to record on DVD and use that as raw material,'s just your own fault)

This is synonymous rather unimportant. It may be regarded as synonymous DV Only I-Frame format. For each DV is just a JPG picture or some kind of JPG. As with other I-Frame Only formats. It is only sometimes not exactly a JPG, because of the format rights. Since the company somewhere to change a few things to call it "evolution" and it's not a JPG, and more conveniently, no one has to pay Lizensgebühren. Is it the same for DVD-/ + R.
I therefore believe it is not entirely wrong, DV regarded as I-frame-only format.
