Frage von Blackeagle123:
Hallo ihr Lieben,
have cut a movie in Premiere Pro (about 5 minutes).
This now needs to burn to DVD, a small DVD menu will I do in Encore.
I want to get the
best quality, since the final size is not really the great role to play in 5 minutes! (Yes I 4,7 Gb space ;-))
I think I need to export it as a Mpeg2-DVD (with the Adobe Media Encoder)!?
But now I understand the 1, and not 2Pass and VBR, CBR, or 4 and 7Mb! It would be very nice if someone could enlighten me :-)
Quite a lot, dear greetings and thanks already!
Constantin
Antwort von Hennig:
mach VariableBitRate, 7mb, 2pass! ;)
Antwort von Blackeagle123:
Hey,
sorry, but sowas gibts nicht!
Nevertheless, thanks ;-)
Antwort von prem:
VBR!
2-pass
7mb
Antwort von Blackeagle123:
Ah, so VBR means variable bit rate, CBR will probably const.!
Can someone explain to me yet what they stand 7Mb and what the difference is between 1 and 2-Pass? Or. what is "pass"?
Thank you and many greetings
Constantin
Antwort von reini 3:
7mb stands for the bit rate used in this case 7Mbit / s (megabits per second) "passport" is synonymous with passes of calculating the film, ie, 1 or 2 runs. When 1PASS the film is now calculate the 2Pass is analyzed in the first continuous film and 2.Durchlauf then calculated based on the findings from the 1.Durchlauf.
2Pass is really only necessary when it comes to extract the last ounce of quality. In 2Pass can save synonymous determine the final file size, and more generally synonymous little space. The calculation of the film but takes twice as long synonymous.
Antwort von StefanS:
That's not really true.
With identical encoder is directly dependent on the quality of the data rate. But it occurs in an identical data rate of synonymous identical quality. That means no preference whether or not 1-pass or 2-pass, the image quality is equal to the same bit rate.
With 2-pass is where it is needed, with a higher bit rate than the average of the set, encoded as and when it is not necessary, with a lower than average set.
So that is synonymous car at a constant bit rate (CBR), a precise calculation of file size, while the variable bit rate (VBR only) an estimate based on the indication of the average bit rate is possible.
With 2-pass you now give a minimum bitrate, for example, 3500, an average, for example, 4500, and a maximum, for example, 7000
The encoder will now try to keep an average of the 4.5 Mbps, as where it is necessary, but allow up to 7 Mbps.
Have you now have a film that fits because of its length with 7 Mbps data rate on a DVD, then you have a min of setting. 5 Mbit avg. 7 Mbps, max. 7.5 Mbps only marginal, no more visible benefits. Will you give as a maximum value even 7 Mbps, you have no advantage over.
It makes sense why I feel that the following procedure:
All films whose length is allowed to be running with a high bit rate (eg 7 to 8 Mbps) on a DVD that will be with CBR and just changed the bit rate.
Should the film be so long that of an average bit rate is possible, for example, only 4.5 Mbps, then, in fact, with 2-pass VBR and appropriate settings for min, max and average.
How can they in turn are entered here, and what makes sense, then turn off depends on the used encoder.
Greeting
Stefan
Antwort von Blackeagle123:
wow
s.euch big thank you all! Now I have the "problem" understood synonymous finally ...
Have rendered with 7Mb CBR, because of the premiere was given. It was only apropos 1PASS! (Since you're practically different notes!?)
7Mb 2Pass gives me no before and Premiere Choice. Why not?
Many dear greetings
Constantin
Antwort von StefanS:
7Mb 2Pass gives me no before and Premiere Choice. Why not?
Because, according to my above statement makes no sense. Therefore, there is indeed the target with 2-pass with a bit rate of an average of 4 Mbps, which in turn fits my above explanation.
You can adjust the targets, but certainly synonymous manual, for example, if you can well due to the length of the film as an example, allow an average 5 Mbit, so you change the rules just off accordingly. These guidelines are not gospel, but that is apparently more often in doubt as the sacred Premiere :-)
Greeting
Stefan
