Frage von micha79:
I have this idea into consideration, and as follows: Instead of the DVD in a double length (with normal quality) to describe, I thought that 60 minutes instead of mini-DV on a 4.7 GB DVD to a 8.5 GB DVD writing. This should, consequently, the quality loss is reduced. In the forum, I have found nothing.
My questions:
1. Geht das überhaupt (with 11 eg Ulead or with another program)?
2. If so, how exactly is the format?
Thank you and greetings
Micha
Antwort von AndyZZ:
Even if you are with a maximum possible transmission rate of 9500 kbit / s (video + sound) kodierst, you can film at 60 minutes to no more than about 4.275 GB. A dual-layer DVD is absolutely unnecessary. Higher data rates are not DVD compliant. DL would be kicked out Money. What else would then be a 2 hour movie.
Antwort von Markus73:
Hello,
and even as a supplement:
If you're at 60 min film on a simple DVD with a quality loss, then you've done something wrong and uses either a bad encoder, or did it badly set. Normally, there is nothing of a loss to see.

I always see that I am under the 8000 Kbit / s limit will remain.
For fast Sichtungsausspielungen I 6000 / CBR,
the difference can be seen at DV, I believe not.

Objection!
at a halfway reasonable screen is definitely a qualitative difference to notice. Therefore, the questioner has not entirely wrong: First, doubling the data rate would be no visible loss of more. Only he can stop the player no longer s.DVD look ...

[quote = "HeikoS"] first proposed a doubling of the data would no longer result in any visible loss.

Well, then you are almost synonymous with the original DV bitrate. That is synonymous not art anymore.
Antwort von Markus73:

60 min to a simple DVD allows such a good outcome as a DVD is technically able to afford is. A further increase of the data is - as written - not possible.
The quality of the result obtained depends upon my experience in the first place and the vast majority of the used encoder s.and very subordinate of the bitrate. To provide in my personal case, the previously used Ligos encoder only at very high bitrates good results and these are even worse than what MainConcept at significantly lower rates of returns.
Whether "it" in theory under any circumstances, the compression can be observed or not, it would like and I can not make lump Specify: I could at least in terms of my commonly used (= very good) settings yet nothing of the sort noted.

Antwort von HeikoS:
So I've learned that TMPEG the best results. But synonymous so you can clearly see the deterioration. but certainly depends on your monitor, and personal tolerance of compression artifacts.

Ok, I personally have never had a direct confrontation "directly from DV camcorder" and "compressed DVD of" made. I have only so long with the encoder settings played until I felt that all the artifacts largely disappeared, of course, always synonymous depending on the normal viewing distance.

Antwort von Daigoro:
If you're not on VideoDVD is dependent features (Menu, Different languages, and interruptible subtitles, chapter) could be synonymous to a more efficient codec than MPG2.
Is yes now enough standalone DVD player, the DivX or WMV (one only needs to note the version) and support to create both a comparatively better picture with the same data to MPG2.
Antwort von AndyZZ:
If you use an external encoder, then you could for example be the length of the GOP, shorten, or the number of B pictures and P change for a better picture to obtain. Times would be interesting to check if only I-frames in MPEG2 stream would. Would it accept a DVD player?
Antwort von HeikoS:
good question, whether he's accepted.
The picture is yet worse, not better. because the efficient, are the P and B frames. Would only slightly when pan or similar image content, even little details which, however, of Picture of Picture differ.

Hm .. could actually be worse. The theoretical 9500 kbit / s must be yes then to 25 full-resolution images are distributed, instead of 1-2 I-frames (with high bit rate) and a number of B and P frames with significantly lower information content. Was probably a mistake on my part. Only I-frames, it would only bring the same if we scale the bit rate could increase. However, it is not.

[...] 60 min to a simple DVD allows such a good outcome as a DVD is technically able to afford is. I would do because there are no restrictions. Those with a good encoder to use for playback and an equally DVD player from elsewhere, he sees no difference between the original DV and the resulting DVD.
The influence of the DVD player should not be underestimated! This must be the MPEG2 stream out, and possibly decompress analogisieren. In a broader sense, there is the same quality range as encoders and A / D converters (of the TV card to the Canopus converter).
Antwort von Quadruplex:
In a broader sense, there is the same quality range as encoders and A / D converters (of the TV card to the Canopus converter). Because I would oppose you. Of course there are differences between DVD players and the better / bigger the screen, the more one sees it. But keep in absolute terms, the differences in the frame. If you anschaust how clueless Lizzie Muller with the technique bypasses, I would say: in practice makes it more noticeable when someone the best box (16:9 / RGB) instead of running in the factory setting (composite / letterbox).
MPEG (and the most current data reduction procedures), the intelligence very well and with intention in the encoder: I have several times by computer hardware MPEG encoder hunted: (Nero, the cheap Geraffel of Sonic - name forgotten - TMPGEnc, ProCoder, HCEnc) - the difference (of course at the same data rate) I see with 'nem cheap DVD players now ...
Antwort von Markus:
Sure, the encoder has a much greater influence on the achievable DVD quality. I wanted synonymous only add that there are other influences exist, of which one must be aware, if you DV originals (directly from the camcorder via Y / C s.Television) with self-DVDs (Cheap player via Scart Composite s.Television ) compares.
Antwort von Quadruplex:
I wanted synonymous only add that there are other influences exist, of which one must be aware of (..) Since we obviously agree :-)
