Frage von nabrande:
Hello. I try to spend my Project HDV (1080i, PAL) to NTSC DVD. First, I walk directly from the Premiere Pro timeline with Procoder Express the film into an NTSC Mpeg2. Then I use DVD MovieFactory 2 (default with NTSC and 'compatible MPEG files do not convert ").
This works, but does not look just great. Furthermore, I am unsure whether this was a "real" is NTSC DVD. They nevertheless play on my multi-player ...
How do I get out the best possible quality, without the compatibility suffers? The DVD will be playable on nearly all DVD players in the U.S..
FYI: I use CBR 7000kBit / s, PCM audio, 16:9.
Thanks for all the tips and ideas on the subject. Perhaps you've had experience here.
In particular, I would be interested to know what settings (upper / lower field?) In Procoder I should choose. And has anyone ever made a with Procoder DVD in the U.S. can play?
Thank you!

That shit is the Picture, is probably s.Encoder.
You should be a good (!!!) program like After Effects, 1440x1080i (50 Hz) on NTSC images in 8 or 10 bit uncompressed (herunterrunterrechnen 60 Hz). This will be a few hundred GB. Alternatively, the synonymous goes into Premiere via the "Export" function.
It is possible, depending on the desired end result, with "deinterlace" (= fields add up to "full frames") at first or only s.end; not synonymous or even to work. I contend After Effetcs makes no deinterlacing scaling. That you have to decide how you like them.
The uncompressed 8 or 10 bit file, you can then export with a good (!) Encoder. And although never with CBR (Constant Bit Rate), but with VBR (variable frame rate). It is advisable to choose, for example 2xVBR to 8 megabits. That is, the encoder has two passes:
1.) motion analysis of the whole video (mpeg2 comes from static images with the same quality at lower bit rate than in fast moving images)
2.) encoding with ever-changing bit rate (VBR);
high bit rate in moving material; lower bit rate settings in standing
I would always recommend between 8 and 9 Mbps. How well does the MPEG file is in the quality depends strongly on the noise. A glittering picture is changing so constantly by pulsing gray point and Farbfragmente in pixels. But you want that "is displayed for you Bildwichtige beautiful" and not the noise is also correctly reproduced. Therefore, at best lend themselves to a more expensive filter, the "entrauscht)" (Denoiser, there are many video editing programs. It's worth as a little experiment.
Also important is the GOP length. If you have a good encoder, it fits the GOP constantly track new. Mpeg2 goes like this: (http://www.netzwelt.de/news/71398_3-know-how-mpeggrundlagen.html)
Next important is the field dominance. Did you initially or later in the section or after the "on-NTSC-scale" progressive video, so you have the field dominance to "none" or "none"
. share Field Dominance meaning is what the field first.
For progressive material, there are not that visually it together one frame shown) (through the inertia of the eye. Do you have a normal DV footage as output you choose "lower field", ie the lower field first.
Now You ask yourself, how can I get 8 or 9 bits 2xVBR on the DVD? The sound has indeed synonymous still on it. The answer is synonymous or Dolby Digital AC-3 and is extremely space efficient. Instead of PCM sound you walk your sound in AC by 3. You almost exportierst the timeline with the finished sound material and just put the the AC-3-econds, resulting in a variety of quality levels (bit rates as 192 kBit, 224, 384, etc.) creates a very economical soundtrack. I guess it saves about a factor of 10 so s.Bandbreite and file size. Say the sound is only in a different format, better quality-and space-saving. It has so reserves for the Picture. Problem: Dolby Digital encoder it cost money. It may be cheaper but synonymous.
At the end you add in a good authoring program, the video track (already as a Mpeg2 file with the best quality selected together) and soundtrack (Dolby Digital) and designed menus, etc.
The authoring program adds sound and image merge then together ( "muxing") and compiles it into a DVD image that you can then burn the DVD-burning program of his choice or the authoring program itself. The image is virtually synonymous in so far as that you can pass it a professional pressing plant.
If you're unsure, have really made a DVD in NTSC standard, check with a media player (eg Quicktime) lower image information which video standard (PAL / NTSC) and Quality Mpeg2 encoder synonymous has actually produced.
I recommend you at least a much better use DVD-authoring program. such as DVD Studio Pro, etc.

Thank you. I consciously use CBR since it (apparently) is less problems mar. Compatibility has. I'll try it but still with VBR (2-pass). This is required by my 50-minute film, probably a few days time encoding.
The encoder Procoder Express itself is not the problem. He really is one of the best.
The export to Adobe Premiere is not really HDV-compatible (known issue) and causes a bad picture. Therefore, solution via Procoder or Aspect HD is necessary.
Too high, one should not set the bit rate, because some players do not sustain it (although they should). I can possibly go up to 7800th
Unfortunately, my encoder is no Dolby Digital sound to Choice. Would certainly be better. (Mpeg audio player for the U.S. is not a good choice, incidentally)
To clarify: Of course, the authoring program (DVD MovieFactory 2) a "consumer" product. This plays no role in the present case, however, because the program makes no further conversions (which is why I wrote that I did not convert the function compatible MPEG files "dialing).
Very good tip with the Media Player / Quicktime. Will I try it.
HAS SOMEONE OTHER SUGGESTIONS?
Thank you!
Antwort von PowerMac:
As long as the conversion does not last.
Even on my G4/800 MHz, is a 90 minutes film overnight. Surely you have a much better PC with 3 GHz up, but there's just overnight or ne long lunch break.

Has anyone experience with Procoder (Express) and the creation of NTSC DVDs from HDV material?
Thank you very much!
Antwort von WeiZen:
Moin,
HDV is TopFieldFirst, so create the MPEG file as synonymous TFF. For DVD, both going as synonymous TFF BFF. For USA and the condition of all players, I agree with you, must have LPCM audio. Especially older U.S. players know no MPEG audio. AC3 is synonymous ehr European.
"Siet unglamorous out" is relative without a statement, but maybe they will change due TFF output as already substantial.

Hello Ulrich
Thanks! Had the impression that lower field (FOR) / upper field (TFF) looks the same. Checked but the DVD is not extremely accurate ...
That HDV upperfield (TFF) is, I knew. What is in this context is theoretically in the production of an NTSC DVD, ie to choose which setting in the encoder you (or does it) does not matter?
Does the following: CBR is the same quality as if the VBR bit rate anyway CRB is consistently high (around 8000). The film is short enough that I can go with a "wasteful" bitrate. For I have the impression that people have misconceptions about VBR ... The procedure is so simple and clever space-saving but not (picture) quality is better (Note: The CBR must of course be correspondingly high).
Do you still synonymous ideas how I can be sure that the DVD really NTSC capable. I am skeptical.
Antwort von WeiZen:
Moin,
Summary:
HDV = TFF>>> SD DVD = TFF
DVD = TFF or BFF, both are DVD standard, the former anyway, BFF is the exception.
CBR or VBR has a minor impact on the quality at high bit rates. VBR which is primarily for low bit rates with complex localized content to get as much as possible on a DVD.
Complex is synonymous noise, since noise is interpreted as a movement and the encoder tries to save this noise. The s.Rande.
But I think I now know what you mean. Can your TV and player, or NTSC? What you see is probably one ore PAL60 Picture. Your DVD player is generated from the NTSC DVD one PAL60 signal. (PAL with 60 fps) Since the origin but was interlaced PAL material, is not that pricklent.
(BUY DVD's is at the origin Proressive. In an NTSC or PAL DVD, the image content of the fields always the same)
So only if your DVD player synonymous wirlich NTSC outputs and can represent your own TV channel synonymous NTSC, then you can judge it. The difference is enormous. I know, therefore, since my TV is NTSC. The MPEG material to me before I look at the video card than NTSC because my DVD player does not synonymous NTSC signal to TV broadcasts, but only PAL60. If it is important for you, you can mail me a PAL and an NTSC sequence, in order to assess.
Antwort von nabrande:
Super. Thank you very much!
Then I will choose in Procoder upper field first (TFF).
Bit Rate (CBR) is right for me 7800 (no longer allowed the program at PCM Choice).
Audio: PCM, 48,000, 16bit
16:9
NTSC 29.97
The fact that my DVD player makes this PAL 60 story can be good. Get it quickly and hopefully find out. The device (Pioneer) is from 2003 I think. The TV (Philips) is NTSC compatible.
Another thing: Does the encoder is actually the speed of sound? How this works exactly? He must indeed be somehow speeds up. (?)
Thanks for your offer. We'll see ...

Antwort von WeiZen:
Moin,
this can be your DVD player is NTSC. Then mothers in the setup are something like output to NTSC (TV) or something like that.
