Encode Rates For Replicated DVD

We're about to send off a master DVD-R to replicate a DVD.
I've been told, but can't confirm, that I can go sky high on my video encode rates for replicated DVDs.
That's the opposite of what I've read for duplicating DVDs.
Any of those out there confirm that I can go to 8 or 9 mbps for an under 1 hour DVD with Dolby2 audio?
Or should I stay at 7.0 as I've always done.
thanks

HI David - if going to replication on DLT then you can max out the bit rate if you wish to... however you need to think about whether you need to.
There is a law of diminishing returns here - anything above about 8mbps and I doubt anyone except a well trained 'eye' could see any difference in the quality. All you'll be doing is increasing the file size. Also, it's worth remembering that there are still players which have trouble reading higher rates off a replicated disc (check the DVD FAQ - section 1.41 makes for interesting reading, although not all of these are down to high bit rates, of course).
I tend to encode at various rates with short samples of material and look for the differences. Where I can't see any, I opt for the lower rate. So far this has served me well!
Don't forget that a duplicated disc is using a very different material for the reflective layer and it is far less reflective than a replicated disc. This is largely why you need to keep the duplicated disc bit rate low - players struggle to read the higher bit rates from the less reflective surface and so stutter on playback.
Personally, if you can't see any difference between 7mbps and 9.8mbps I'd advise staying at 7. If there is a difference for your footage then try again with 8mbps, but don't be lulled into a false sense of security over the fact that a replicated disc should be able to have 10.08mbps combined bitrate... the quality of the player is really the issue. Whilst most will, some won't, though all should!

Highest peak rates for replicated DVD-9 or DVD-5?

Which is the highest peak rate that is most commonly used for replicated discs for all the data streams, and for video? I've tested some well authored popular mass production music dvds with DGIndex and often found video peak rates to go over 8.5 or even 9.
Still quite often it's said for example here http://www.createspace.com/Special/AuthoringNightmares/03/BitsAndBytes.jsp?cfxwasredirect ed=true
that for replicated discs you shouldn't go over 8Mbps rates for video.
I'm having one subtitle track and, 2.0 Dolby Digital and 5.1 Dolby Digital audio tracks in my project, but if the spec says the peak limit for all the assets in DVD-video is around 10Mbps, 9.8Mbps (as I think Neil referred in his alternate bit budgeting guide: http://www.adobeforums.com/webx/.3bb7dccd ) or as 9.6 (as I think Neil referred in: http://www.adobeforums.com/webx/.3bc2e248/0 ) why the video peak rate needs to be that much under what would be possible to be used with subtitles, 2.0 and 5.1 audios? There is like 0.448 Mbps for 5.1audio, 0.256Mbps for 2.0audio, 0.04 Mbps for subtitle, it would leave at least 8.5 Mbps for video? So, it is a little bit confusing what really is the usable DVD peak for replicated DVDs (DVD-5 or DVD-9)? Is it ok in my project to use 8.6Mbps for video if it fits the 9.6Mbps or what ever is the exact scope?

What are best Mpeg encoder settings for making DVDs?

In switching from PP1.5 to CS3 the procedure is different for making DVDs and we have to encode mpeg files that later get picked up by Encore DVD build proces. What are the best mpeg encode settings for making the DVDs?
Thanks,
Chuck Taylor

Question:
If you are doing a video that is small enough that you are not worried about size, what is the absolute best quality encoder settings? Would a Continous Bitrate result in a higher quality file generally? VBR is for trying to make a smaller file I assume.
I'm frustrated with even white letters on black titles that have some flicker. I just don't seem to get the smooth quality I desire.
Should I look at a different encoder?
If you output PP3 to an AVI and then import it into encore, isn't there a reduction of Q. due to the save to the AVI file?
thanks.

Future encoding time for HD DVDs!

Wow! For those of us who think our encoding takes a long time now, I read in a recent HD trade magazine that stated a 2-hour theatrical movie is taking 100 hours to encode for an HD movie. It didn't say what programs or systems were being used. If this is true, I think I can wait a little longer before I need to make an HD DVD.

Hey kenneth,
using the preset in HD DVD H.264 preset in compressor can take that long.
we would need more information on how exactly you are compressing your video, also what your native codec is.
we need more information such as:
-are you using presets
-if you are NOT using presets (you set your own settings) what are they
-what type of file are you importing into compressor and with what codec
-what kind of and how many drives do you have in your G5
-are your drives stripped (using RAID)
-how much RAM
-what other applications do you have open when encoding
(see what i mean, all this info would be VERY useful)
one of your questions was if encoding with the H.264 codec was really this time consuming. the answer would be yes, although it sounds like you might have set some other settings manually. but i will not assume, i will await a response.
also, your last comment is a little confusing since once again, more information was not included.
do you mean that both H.264 and high bit-rate mpeg2 codecs work in a G5, so it will play back on the newer versions of Apple DVD Player?
or do you mean that the h.264 codec will play on toshiba's HD-A1 and HD-XA1 hardware players, such as the high bit-rate mpeg2 codec?
if the former, then you are 100% correct!
if the latter, then you would be 100% incorrect (unless toshiba finally delivered their much promised firmware update, which would include *.ac3 [dolby] playback as well).
please advise

Maximum CBR for replicated DVD-9 ?

I'm compressing audio and video for DVD-9 replication. I wasn't too happy with VBR, so I'd like to use CBR. I have room for the highest bitrate possible, but know there are issues if you go to high. What would be the highest CBR without causing problems?

The max rate is 10.08 Mbps (Page 43 DVD SP 4.1.2 Pdf Manual)though some players fall short of being able to play items approaching the maximums properly (more so with non-replicated disc) with video a max of 9.8 Mbps. Video, audio and subtitle streams count to the max Mbps (Page 44 Pdf )
That being said you should try to limit the rate to the lowest that gives you acceptable results. (That is what I aim for anyway). Usually in general with AC3 audio 8 at CBR should work fairly well.
What were your settings and how long was the running time of the video?

How do you fix error message "data rate for this file is too high for DVD. You must replace this file with one of a lower data rate".

When trying to burn a DVD it will go through the encoding step and at 98% we see the message 'data rate for this file is too high for DVD. You must replace this file with one of a lower data rate". We need help to correct this so we can complete burning to DVD.

Best average bit rate & max bit rate for DVDs playing on laptops...

I encode and burn many DVDs for use in regular DVD players....usually in the half hour range and have been encoding with Compressor 3 using these specs:
6.6 average bit rate
7.8 max bit rate
Those same DVDs, which play flawlessly in the DVD players, can occasionally hiccup when played from a laptop. Should I change the max bit rate from 7.8 to 7.7. or lower? Is that the biggest part of the equasion that may affect a laptop's ability to play without choking?
Many thanks,
John

Thanks for all your help, David S, but the point is
that I have tried many different bit rates, from 4.0
to 7.0, and I don't have time to waste all day trying
different bit rates for an 8-minute project.
My main question is: Why would it work fine on all
of my other short projects, including the 8-minute
one, and then when I cut out 20 seconds of that same
project, it starts screwing up!?!
I am going to try trashing my preferences. It is
starting to seem like a corrupt pref file to me.
It turned out to be a corrupt pref file, as I thought. Thanks for your many, many questions, David S.

Need advice on encode settings for Premiere file to be played back on DVD

Hi - hoping someone can help me with my encoding settings. I seem to be on the right track because everything looks good until you play the video on DVD.
I use Windows Movie Maker to encode my exports to DVD. This software does not accept MP4 but it seems to accept a variety of other files and one is WMV. I first exported a WMV clip from Premiere at 1920x1080 (the raw video and graphics are also in that size). Then I exported another WMV clip to 1280x720. I just wanted to see what both of them look like on a DVD during play back.
Here are the export settings:
Here is what the1280 WMV looks like when it's played back on my desktop computer in Windows Media player. As you'll see everything looks very clean:
I then imported the 2 WMV clips into Windows Movie Maker, selected the 16:9 settings, and it encoded them into a finished DVD. I then played the DVD back on my 50 inch TV in my living room. Below you'll see a photo I took of the 1920 clip; notice how the text looks jagged:
Then the photo below of the 1280 clip looks much cleaner.
But obviously I'd like for the finished DVDs to look if possible even cleaner than the 1280 photo above - hopefully like it looks in the photo of the WMV playing back on my computer. These videos will be distributed to different local offices.
Are my WMV settings correct? Should I export to other than WMV? How can I improve on the 1280 DVD photo above so everything looks even cleaner (if possible)? I have Adobe Encore - should I use that instead of Movie Maker?
Any help is appreciated. Thanks.

"current encoder settings for bit rate and sample rate are invalid" message

I have some files I am working with. Details and what happened:
Had some music files where I was doing some trimming/splitting. Files worked fine in itunes.
Open the files in Quicktime Pro 7 to trim them. Exported to aif.
Opened the files with itunes. They open and play just fine.
In Itunes I click"create AAC version" to convert them.
I receive the message "An error occurred while trying to import the file. The current encoder settings for bit rate and sample rate are not valid for this file."
I don't know what to do from here. Suggestions?
Thanks.

Make sure that the AIFFs that you export are set for 16 bit PCM.
Also, assuming that you are using 44.1 kHZ sampling in your AIFFs, make sure that you are not trying to use 48 kHz in the AAC.

Encoding file size for standard DVD too large - please advise

Hi - I shot an 6-hour training session that went well. I shot it at 1280 x 720. For the web version it will be no problem, as I'll just export to F4V.
But i'm having a difficult time figuring out the export settings for the DVD. I know that the disk is limited to 4.6 GB. I broke up the sequences in PPro CS4 to about 30 minutes or so (some are smaller or larger than others).
I first exported to QT but found that a 30-minute export way too large (8 GB) and Encore brought it down to 2 GB but that that will still only allow me to put 60-minutes on one DVD vs. the almost 2 hours I want to get on 1 disk.
AVI is even worst.
I know that widescreen is a larger size so I'm willing to make it standard NTSC but I just cannot figure out which export setting in PPro CS4 to use to make this work.
Can someone advise me on this?
Thank you.

>exported a 36-minute video in QT. It's 8 GB in size. I imported it into Encore, which encoded it down to 2.5 GB
I don't use QT at all (Quicktime is not even installed on my computer) instead using DV AVI to go from AVCHD to Encore to create a DVD http://forums.adobe.com/thread/652694?tstart=0
But, as you found, Encore encodes your "raw" input file into a "finished" DVD file which is much smaller due to how MPEG/VOB is structured
I once put 2.5 hours on a single side DVD... but that was a slideshow w/music to be a background at a party, so there was NO motion at all for the encoding process to have to adjust for to produce a good image
A fast moving video (soccer game) is going to require a lot more DVD space to produce an image that is not blurred due to the speed of movement
For a training session with (I presume) low speed movement, simply export your project in 2 hour sections and have Encore do automatic encoding to create the best fit on the disc
Note that automatic encoding is only (as far as I know) for video that you have not already compressed by using the Mpeg-Dvd output setting

Best Compressor encoding setting for DVD

I have an 80 min FCP project. It is a stage show where part of the frame is dark and the stage is light with gels and the Dancers. What is the Best encoding setting for a standard size DVD
I tried 90 minute 2-past best DVD but there was severe blocking/chopping.
Any tricks & tips?
Thanks

I don’t understand that. (Me not so smart.) If there is a standardized Unicode value associated with glyph X, then how is it that none of the Unicode character sets in Firefox abide? Add a font? As I understand it, a font is just a re-representation of known characters. It seems like I’m hearing that not only does there have to be a character set decode of the data I’m viewing, but also a font that takes that Unicode value and translates it to something visual. That doesn’t wash. Between databases data is converted to and fro, irrespective of OS/App fonts installed. Sybase <-> Oracle doesn’t need a font installed. Viewing from SQL I don’t need a font installed.
But – thank you cor-el for effectively resolving my problem – even if I don’t understand the logic. Thank you for taking the time to reply!

No Audio? On MPEG-2 encodes for SD DVD

Help. I'm new to Compressor.
I'm trying to encode an MPEG-2 Elementary Stream for SD DVD production. According to the documentation DVD Studio Pro will only work with the elementary streams but it also states "that no audio is provided in this stream". So how am I supposed to encode to MPEG-2 (supported by DVD Studio Pro) and get my audio to go along with it?
Am I missing something obvious? Here are the details:
Source - 1080i60 HD .Mov file
Encode - MPEG-2 16x9 elementary stream.
Video comes out fine, just no audio to be found anywhere?
Thanks.

Correct. When you bring your source file into Compressor you need to create two settings. One setting for your MPEG-2, another for your Dolby Stereo .ac3 file. This will output two separate files, one video and the other audio. You then bring those files into DVD SP for authoring.
However do not use the default Dolby 2.0 setting. Start with that but change the dialog normalization to -31 and the Preprocessing Compression Preset to None.

Low dvd-read rate for COMBO x48

ive bought this MSI 16x combo-drive x48 recently ... when used initially it was set to PIO mode in windows and max data transfer for a dvd wuz 2845 kB/s. sisoft sandra shows the drive as 2X.
Later i changed it to Ultra DMA Mode 2 . now still the max dvd-read rate is (4549 kB/s) .. sisoft sandra now showing this as 5X drive
these measurements were taken with SiSoft Sandra, DVD-Decryptor, v_Strip .. all new versions ..
ive tried several dvd's all original releases, with the same or in most cases lower performance ...
previously when using a 12X Aopen DVD-Drive i used to acheive speeds upto 12,500 kB/sec. while reading dvd's
Now according to your claims im supposed to get a performance of 21,000 kB/sec for DVD ? and im getting only a fraction of that performance ...
my system config is:
P4 2.4 Ghz 533FSB
Gigabyte 8PE667 Ultra 2 Mobo
MSI GeForce FX5600
512MB DDR333 (PC2700) TwinMos
400W Rhycom PSU
80GB Seagate Barracuda 2MB Cache
80GB Western Digital 8MB Cache
Creative Vibra 4D SoundCard
56K Rockwell Modem
MSI x48 COMBO Drive
Windows XP Professional (no service packs) ~2002
WinDVD Platinum 5
Adaptec ASPIi v4.71.2 (for winXp)
what can possily be wrong .. ie. sumthing with the windows that i shud check ? or sumthing with the mobo ide device setting(ATA33 ATA66/100) currently set in bios as Auto
i bought a 16X to give a better performance not to get this degraded performance ...
pls do send a reply soon .. or i mebe forced to think that MSI is only good at mobos !

Hi:
Try to install the drive as an only secondary MASTER.
In the primary channel, use the fastest HDD as MASTER and the slowest HDD as slave.
Note: USE The primary channel for the Hard Drives (HDD) and the secondary channel solely for the combo drive.
Hope that helps.

Bit Rate for Mixed angle DVD

What bit rate will give an decent quality image if there are 4 video streams (v1-edited video,v2-4 source angles), 1 ac-3 audio stream, 1 mpeg1 audio stream. Three of the video streams are alternate angles that popup for brief ( 1 to 5 minutes ) periods of time in a 1 hour wedding ceremony. I guest the safe bit rate for all streams is around 8.5, the manuals say the max is 10.3 mbps. Can I mix bitrates for video in a mixed-angle track or do they all need to be the same?, is four video tracks just too much info ?
Thanks for all the help !

One last question; if there are four user selectable streams are you adding up the bitrate for all streams or is the total just the stream that's being played plus any audio that gives you your total ?
thanks
