H.264 vs H.264 Blu-ray VBR 2-pass bit rate presets ...

If I select H.264 1080i, 29.97fps VBR 2-pass PP CS6 is recommending a target bit rate of 30 mbps and a max of 40 mbps. However, if I switch to H.264 Blu-ray I get 25/30. I was curious if there are logical reasons here for the difference.
In case it matters ... home movie (birthday parties, spring break trip, etc.), target output is playback on PC and PS3, and then Blu-ray disc. I've given up on the one file concept and was leaning towards an .mp4 and then separate .m4v/.wav files to feed to Encore. Curious what you would set for bit rates, if you would go VBR 2-pass, etc. (encoding time is not an issue).
Thanks

Blu-ray has bitrate limitations that computer files don't. (That's my guess on why the difference.)
Anyway, a preset is nothing more than a starting point, not the final authority on what you can export.

H.264 MVC for 3d blu ray

h.264 MVC for 3d blu ray: there are some way for encoding the 3d stereo video with apple computers/software?
alessandro

You can make side-by-side 3D content for certain types of 3D TVs (that will play side-by-side), to play through Blu Ray Player (can use standard DVD though!). Need FCP 7. "Share" feature for Blu-Ray.

Blu-ray project / change of frame rate

I am shooting 1080/24p format ( I live in Finland/Europe ). I have created blu-ray disk from my project
with original settings ( FC/share ). Everything is working more than fine.
I sent this disk to my American friend...the menu opened and BD player started, but no picture. This was actually a test and it failed. I know issue of different television setting USA/EUROPE...but I had to try.
My question: Is it possible to change frame rate 25p to 24p or 50i to 60i ?

can anyone recommend me some, so I can avoid running a bunch of tests please.
Winston,
You'll probably be happiest using either the JES Deinterlacer or MPEG Streamclip with the "blend" option activated. (Unless you've chucked them for some reason, I assume you still have both on hand.)
Take care,
Jon

Export flash vid with VBR? (variable bit rate)

Does AE CS3 have a choice of VBR when exporting Flash Video (FLV)? I'm going thru the Render Queue, but can't find where to change it from CBR.
Thanks, Mates!

No, I don't think so. After Effects only does one-pass rendering/compression, so you're probably better off with Flash Video Encoder or something similar.

Encore insists on transcoding H.264 Blu-ray encoded file (Blu-ray legal)

I have a Blu-ray legal .m4v file encoded out of Adobe Media Encoder as H.264 Blu-ray VBR 2-Pass, maximum render, target 25Mbps, maximum 30Mbps.
My project is H.264, maximum 40Mbps.
Encore keeps listing the video file as untranscoded and wants to transcode it.
I've tried encoding just a portion of the video file instead of the whole thing using the same settings and when I bring this into Encore it recognizes it as Blu-ray legal and sets it to "Don't Transcode".
Can anyone think of a reason as to why this is happening? I really don't want to sit through another eight hour encode that could degregade pq further.
Thanks!

A .264 file from x264Pro or MeGUI that is BD-legal will import into En and be automatically set to Do Not Transcode. So the file extension isn't the problem. There are some esoteric H.264 parameters in x264 that must be set precisely in order to have En set the .264 file to DNT. I suspect those same parameters will have to be set in MainConcept's encoder.
If you want to jump in the deep end, here are the x264 parameters that produce BD-legal output that also make En happy:
program --pass 2 --bitrate 16000 --stats ".stats" --open-gop bluray --interlaced --pic-struct --level 4.1 --bframes 3 --ref 4 --slices 4 --aud --nal-hrd vbr --b-pyramid strict --keyint 30 --min-keyint 3 --vbv-bufsize 30000 --vbv-maxrate 40000 --weightp 0 --colorprim "bt709" --transfer "bt709" --colormatrix "bt709" --output "output" "input"
Obviously interlacing, bitrate, vbv-maxrate and such can be set as desired based on the source footage and delivery requirements.

Blu-ray Error: "file already exists", Code: "6", "Audio buffer underflows. Total bit rate too high

Hopefully someon can help me out here - I'm stuck in my tracks. I'm reading through lots of threads on this topic, but don't understand what is going wrong here. CS6. Note: I have used Encore prior to put this material on a disc. I presently have a separate sequence paired down with only about 1/5 of the whole production. 1920x1080i, 29.97, H.264 Blu-ray, VBR 2-pass, PCM inside PP to produce .m4v/.wav. Here is what is confusing me - I tried a target of 10 and a max of 20 and I still get this error. I have tried different max bit rate "Default Transcode" settings in Encore as well. Note the time code listed "0.000000" - maybe that tells someone something. I don't really understand Encore yet, so maybe it is something I set wrong in Encore vs. my exports?

There are many similar, but not identical errors. And I assume you had already followed John's advice to review older threads. It is true they never quite pin a single set of issues down.
What specific version of Encore? Updated to 6.0.2.004? Encore staff once said updates solved some of these errors.
You say .wav for source files in Encore. But what format in the project? ac3?
Your versiono f the error is different from other one I see because it has a "audio buffer" rather than "video buffer" underflow.

Blu Ray via Encore: H.264 or MPEG?

Hi,
I want to create a Blu Ray via Encoe Export to be played on a Samsung 1400 Blu Ray Player. Which settings would you use? H.264 or MPEG? What is the best bit rate?
Regards, Sascha

h.264 will give you better quality at a given bit rate. If memory serves, something between 19 and 30 Mbps.

Blu-Ray authoring workflow

Hi all,
I am just starting to work with Blu-ray. I created my first disk both BR-RE and a BR-R disks. I have been using Premiere Pro cs5 with latest updates for a while now. I have been taking HD content and exporting a dvd mp2 file with the following settings. 7 mbit max, 4-5mbit target, 1.5-2.5 min setting. This works flawlessly, never a problem. If I go higher let's say to 8 mbit I get glitches stops and starts playing back the video.
First, I exported a 1920x1080 timeline in PP CS5 from my new Canon 60D camera as a Blu-ray mp2 file. I get the same problem in Encore that all of you are having which is that Encore says the m2v file need transcoding (untranscoded). I already transcoded the file in media encoder from PP so this should not need to be transcoded again in Encre. PP say that there is an update to media encoder that I can update. Maybe this will fix the issue?
I also would appreciate some help getting stated with transcode setting for Blu-ray. One thing using the canon 60D do I need to convert the mov file first to Apple Proeres format before editing in PP?
Next, what's the best bitrate setting to use to export/ encode the file. I used the default settings in media encoder which I think was 15MBIt. This does not play correctly in my Blu-ray player. So I have to find a better sweetspot. I have read that 20 or 25mbps is better?
And is it true that i should use the Blu-ray h.264 setting instead of Blu-ray mpeg2? I think the quality of Mpeg2 is really good.
One last setting issue in Encore. There is a setting either to output an ISO image file in either BR-R or BR-RE. What's the difference? I just outputted a BR-R image file and wrote it to a BR-RE disk and it played just fine so I was wondering what the differences in the settings? I would like to be able to output one image file and use it for both -RE and -R disks.
Oh, from my camera I just copied the mov file to a folder on my HDD and then I just imported the mov files into PP as a timeline. The Video does play a little slow but not that slow on my PC.
Thanks for the help,
John Gerard

Set the vbr to 1 pass or use the H264 codec.
Best is to set the mbps same as the footage.
The default settings work just fine.

Sorenson Squeeze H264 settings for blu-ray?

I'm trying to create a blu-ray in encore, and when importing an H264 using squeeze's blu-ray preset, encore wants to reencode. However, a blu-ray mpeg2 created from squeeze's presets works fine with encore. I'm not able to have Adobe Media Encoder installed on the computer that I am encoding from. Any advice? Here are the settings:
Mainconcept H.264
2pass vbr
1080i 29.97
25,000 Kbps
constrain at 30,000 Kbps
level 4.1
high AVC profile
interlaced
top field first
CABAC encoding entropy mode
key frames every 300 frames
auto key frame on scene change (50)
use b-pictures 3
use b-slices as reference (unchecked)
multiple slices (0)
reference frames (2)

My choices entropy encoding are either CABAC or CAVLC. I tried the various combinations of main/high and 2-pass/1-pass with CAVLC with no luck.
I downloaded MeGui but haven't had a chance to try it yet since it doesn't take quicktime reference files. My original media is coming from an Avid project, so I suppose I could export a DVCPRO HD quicktime (the media's original format) to test. Are there any settings in MeGui I need to be aware of or does it have a preset that is close enough to what I need?

Encore CS6 Blu-Ray "fatal error" during build

I have an external ble-ray drive that I just bought from OWC for my MacBook Pro. I have created a project for a wedding that has 3 sequences. Everything looks good, and the building/burning process gets about 90% done and I get this:
Blu-ray Error: "fatal error", Code: "6", Note: "Video buffer underflows. Total bitrate is too high near time = 0.0000000 seconds - Failed to multiplex with maximum IG PTS: 54900000 (in 90kHz).
I am new with Adobe, especially Encore. This is my third try with the same message. I tried building to Blu-Ray disc as well as Blu-Ray image. I have several couples waiting on a Blu-Ray disc for their wedding video, and I can't produce one! So frustrated!
Any help is MUCH appreciated!

This is actually a very interesting error message. There are 4 blu-ray authoring programs that can display a error message that contains "video buffer underflows" when authoring a Blu-Ray with H.264.
These 4 blu-ray authoring programs are: Sony DVD Architect Studio, Sony DVD Architect Pro, Adobe Encore and Sonic Senarist BD.
Another interesting thing is also that the complete error message that is displayed by both Sony DVD Architect Studio and Sony DVD Architect Pro is exactly identical, word for word, with the error message that is displayed by Sonic Senarist BD.

Problems creating and exporting Blu-ray

On one of my first efforts at using Encore CS3 to create a Blu-ray movie I ran into some puzzling problems. I do not know if these are bugs in Encore, problems with my computer, or errors on my part in setting up the project.
A few weeks ago I created a movie of length 2:06:21:11 using Premiere Pro CS3. At first I needed a DVD of this movie and I did not have sufficient storage to export to Encore for Blu-ray, so I exported MPEG2 video and .wav audio for DVD. I imported these assets into Encore (complete with chapter markers) and produced my DVD with no problem.
Later, having obtained more external storage, I returned to the Premiere project and exported the movie as MPEG2 for Blu-ray, using the high-quality 1440x1080 preset. I imported this file and the associated .wav audio file into a new Encore project (I was disappointed not to find the chapter markers here) and proceeded to create menus similar to those
from the original DVD project. Everything went fine until I checked the project and found that it exceeded the Blu-ray disc size: the projected build size was 25.61 Gb.
Now the file sizes were as follows:
The MPEG2 video file was listed in Windows Explorer as 23,035,133KB, which translates to about 23,588,000,000 bytes. The same file was listed in Encore as 21.9GB, which is itself a bit of a puzzle: even if the file were just under 21.95GB, rounding down to 21.9GB, this would be only about 23,569,000,000 bytes, so I would think the actual file size would have been rounded by Encore to 22.0GB. Incidentally, 7,582 seconds of video at the target bitrate of 25,000,000bps would come to about 23,694,000,000 bytes, so the 2-pass VBR was pretty close to the target.
The .wav audio file was listed by Windows Explorer as 1,421,502KB, which comes to about 1,456,000,000 bytes. It was listed in Encore as 1.3GB -- once again, I would expect Encore to have rounded the actual file size to 1.4GB.
In any case, the real audio plus video file sizes are just a bit too big for a 25,000,000,000-byte Blu-ray disc even if the sizes listed by Encore would just fit. So I decided to use Dolby audio at 192Kbps to reduce the audio to one-eighth of the size of the .wav file.
First I did this by specifying a transcode preset for the audio that included Dolby, rather than leaving it set to "Don't Transcode". A check of the project still showed that it exceeded the disc capacity, and initiating the Build process STILL SHOWED A PROJECTED SIZE OF 25.61 GB -- as if the Dolby transcoding were being ignored completely.
Next I transcoded the .wav file to see if this would change the size estimate. The transcode took some minutes (during which time no progress bar appeared in the transcoding progress panel). Finally the audio file was listed as "Transcoded", but a check STILL SHOWED 25.61 GB.
Finally I transcoded the .wav file to Dolby stereo at 192Kbps using Vegas Platinum + DVD, replaced my original audio file with this one on the timeline, and marked it "Don't Transcode". But a check STILL SHOWED 25.61 GB. The Dolby file was listed by Windows Explorer as 177,678KB, or about 182,000,000 bytes.
Now this certainly should have fit on a Blu-ray disc. It is slightly shorter than the third bit-budgeting example in the Encore manual, and it has no motion menus or slide shows. The video plus audio, both "Don't Transcode" assets, total about 23,770,000,000 bytes, well below the 24,500,000,000 bytes suggested in the manual to allow a "very conservative" 2% margin for overhead.
So I figured the size projections were erroneous and I ran the build. It produced a Blu-ray folder with total size 24.6GB, which translates to 26,414,000,000 bytes, or about 1,414,000,000 too many. Looking in the Blu-ray folder, I found that the main MPEG-2 TS file (named "00000") contained 25,814,922KB, or about 26,434,000,000 bytes.
So I ask Adobe and any expert participants in this forum for their help understanding the various problems men

I apologize for the length of the previous post -- I had to explain a lot so that you might understand what was going on. The editor chopped off the end of my message, which was to have been:
So I ask Adobe and any expert participants in this forum for their help understanding the various problems mentioned above, specifically:
1. Why did the estimated file size come out so much greater than the sum of the known video and audio file sizes?
2. Why did the estimated file size not change as PCM audio was replaced with Dolby?
3. Why did the actual build file size come out so much different from the estimate?
4. Is Adobe's stated "very conservative" margin of 2% in fact too small for Blu-ray?
5. Why was there no progress bar when transcoding .wav audio to Dolby?
6. Why did no chapter markers come over into Encore in the MPEG-2 Blu-ray file?
7. Why were the file sizes in the Project panel of Encore, for the two "large" files, slightly smaller than they should have been?
Please excuse the length of this post, and thanks in advance for any help in solving these problems. I can certainly work
around them by encoding to a lower bitrate but I would prefer to address them directly.

Blu-ray says capacity too big when burning DVD Rom Folder Encore CS4

I have tried 3 times now to burn a Blu-ray Image file with a DVD rom Content Folder. The Blu-ray Image size is 45.90gb and the content folder is 1.6gb. The disk is a Sony DL 50gb Blu-ray. I have not tried to burn direct to disk because cost of Blu-rays. I am using Encore CS4. Is it that you cannot make an image file with DVD-rom for DL Blu-rays. Is there a number preset by Adobe for image file size for DL Blu-ray. Please help

45.90 GB on your hard drive and 1.6 GB on your hard drive add up to 47.60 GB.
In computer GB, (47.60 x 2^30) that's over 51 billion bytes. Sony and other blank media manufacturers report the capacity of their blank discs in normal GB (50 x 10^9), or 50 billion bytes.
Your project is too big to fit on the blank media that you have.

VBR or CBR for H.264 Blu-Ray?

When encoding a 2 and a half hour H.264 Blu-Ray project from Media Encoder, is it better to use VBR 1 Pass, VBR 2 Pass, or CBR? I want it to be a total of 15 Gigs when it's done encding in Media Encoder.
When working in DVD Studio Pro, I always use CBR without a problem. Those were not Blu-Ray discs though.
My Target Bit Rate is at around 12
My Max Bit Rate is 25 or 20.
Media Encoder 5
Premiere Pro cs 5.5

For more information on a description of Constant Qiuality (CQ) vs Constant or Variable Bitrate (CBR, VBR) have a look here on page 5..
http://www.x264pro.com/wp-content/uploads/x264_PRO_Help.pdf
The Adobe bundled h.264 doesn't have CQ though so it's best to go with VBR vs CBR because it will steal bits from less complex frames before and after when it's needed. It will also allow short term bursts of information (up to the Maximum threshold) so that when bits are needed it can use them. - eg a scene change.
Also, do 2-pass. The first pass it will learn about when it's going to easy and hard to make frames. With that information on the second pass it can steal from the future since it knows that the future frames might not need many bits.
Also, if you have a very simple frame it will reduce the bitrate and save you on the total size. If you use Constant Bitrate you don't have any of these efficiencies.
Constant Quality doesn't look at the problem from a bit perspective. It makes a variable bitrate based on the quality of each frame you want to hit.
'hope that helps.

H.264 Blu-ray via Adobe Media Encoder
I can render Blu-ray material, and even burn it in an internal LG 10x Blu-ray burner that I installed. The result was wonderful when played back on a Blu-ray player and HDTV.
What I cannot figure out is why I have to render projects in small little segments, rather than one large one, and then line them all up on a timeline in Encore. I then have to rearrange my chapter points, since Encore places a chapter marker at each clip. It's not the biggest deal in the world, but it's just annoying.
I've tried different settings, and the one that gives me the most success is starting with the preset for H.264 (Blu-ray), HDTV 1080p 23.976 High Quality, and switching the Profile from High to Main, and leaving the rest alone. I'm not sure if I tried HDTV 1080i 29.97... maybe I should. Whether it crashes or not seems to depend on how many effects are in the clip, or how long the segment is, but I can usually get away with up to about 10000 frames of video without a crash. The crash almost always occurs during the second pass of VBR encoding. It closes Premiere and offers the crash report window, which I am not good at decyphering. Anyway, I always submit the crash report with what I was trying to do. Adobe has many of them from me now.
Can anyone shed some light as to why it only allows 6000-10000 frames go through this encoding process? My system will show that it only used about 6 out of 16 GB of RAM after a fresh reboot. It helps if I reboot between each encode session, as well. If I try to encode two short segments without rebooting between, I usually get a crash. Also, I can encode DVDs just fine with the same project. I encoded the 105 minute movie with all the same effects, clips, etc. and the DVD was flawless on the first try. It's just the H.264 Blu-ray setting that jacks it up.
I'm glad I can get the thing done piecemeal, but I was hoping someone could at least explain why it's so difficult. (:

I would agree, and I think it must have to do with RAM. When I get a segment exported successfully, the Activity Monitor shows very close to all 16 GB used in many cases. I surmise that when the program sucks too close to all 16GB up, it crashes.

CS4 - Adobe Media Encoder - Encore - H.264 Blu-ray

As many folks are aware, Encore's transcoding can sometimes be less than optimal. I played with the AME settings and with the help of other folks on these and other forums finally determined all the right settings so that Encore would treat my DVD quality videos as native and not attempt to transcode them.
I am now trying my hand at Blu-Ray and am running into similar problems but so far I have not really found any answers that have worked. Based on my research, the following settings should work:
AME
Format: H.264 Blu-ray
_Video_
TV Standard: NTSC
Frame Dimensions: 1920x1080
Frame Rame: 23.976
Field Order: None (Progressive)
Pixel Aspect Ratio: Widescreen 16:9
Profile: High
Level: 4.1
_Bitrate Settings
Bitrate Encoding: VBR, 1 Pass
Target Bitrate: 18
Max Bitrate: 22
_Audio_
I have Multiplexing disabled because I am using DD 5.1 encoding and for DVD quality, I learned that Multiplexing is a no-no to prevent Encore from trying to transcode things. I assume the same thing applies to Blu-Ray so I'm not really worried about the Audio.
Encore
_Project Settings_
Authoring Mode: Blu-ray
_Settings
Television Standard: NTSC
Codec: H.265
Dimensions: 1920x1080
Frame Rate: 23.976
Fields: No Fields (Progressive Scan)
_Automatic Transcoding
Maximum Audio/Video Bitrate: 25.0 Mbps
_Audio Transcoding
Audio Transcoding Scheme: Dolby Digital
I have tried a number of other settings around these (including using 29.97 frame rate to match my source), but after 4 days of trying different things with AME, I am completely stumped. What I am primarily looking for is someone to be kind enough to post their settings, in the level of detail above, that allow them to import an asset into Encore so that it doesn't want to transcode the video.
I know there are other tools out there that can do these things, but I paid my $ for Adobe Mastersuite so that it would do all these things for me. If at all possible, I would really like to stick with just these tools.
I am not sure if it matters, but my source is a Panasonic HDC-TM700 set to record in 1080p30 (I don't use their proprietary 60 frame format). I have successfully downconverted this source with AME to DVD quality. I have also successfully outputted from AME to 1080p that was uploadable to Youtube. Again, I'm not sure that it matters other than I can make useable video from my source. Here are the properties of the video according to Premiere:
Type: MPEG Movie
File Size: 2.6 GB
Image Size: 1920 x 1080
Pixel Depth: 32
Frame Rate: 29.97
Source Audio Format: 48000 Hz - compressed - 6 channels
Project Audio Format: 48000 Hz - 32 bit floating point - 6 channels
Total Duration: 00;22;23;25
Average Data Rate: 2.0 MB / second
Pixel Aspect Ratio: 1.0
My actual clip is about 6min, but my intention would be to use clips of up to an hour in length.
Oh, I'm not sure if it is clear from my above information, but I am not using Adobe Dynamic Link. I'm not sure if that is where my problem lies, but my one attempt to use it did not produce the results I was looking for either.
Thanks in advance for your time and for making it this far into my post
-Jay

Well, that's a bit of a disappointment. I have to imagine most Adobe users are bald due to Adobe providing settings/output options that it's own software doesn't like. I really don't understand the sense of that.
In any event, I attempted to use:
Format: H.264 Blu-ray
Preset: HDTV 1080i 29.97 High Quality
And Encore still wants to transcode the video. It also wanted to transcode the audio that the format put out (PCM audio). I tried messing with some of the settings in Field Order, Profile, and Level and no love all around. I also tried one of the 1440 formats and no love there.
Does anyone truly have this working natively or am I just chasing my own tale? It really should not be this hard to get Premiere to output something that Encore will use without difficulty.
