Compressor:  setting max bit rate for VBR audio

Hi,
I am using Compressor 3 to transcode DV to H.264.  I want to encode the audio to AAC VBR wtih a max bitrate of 256.  Under the Settings tab, under audio, for VBR there is a slider from good to best.  what does this mean in terms of max bit rates?  How can you use this slider in a meaninful way?
There is a setting for Average Bit Rate, where you can select a value.  do we konw what the max bit rate would be?
thanks
dan

Good question about the slider…and I really don't know the answer. Why don't you try a test: crank it to one extreme and then the other with a representative source file and see what impact it actually makes on the properties of the respective output files.
Good luck.

  • 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.

  • Why does FCP set 30fps TC Rate for certain audio clips that lack TC stream?

    Hello folks,
    I'm cutting a DVCPRO HD 720p50 feature at 25fps on FCS2 w fcp 6.0.3. (Used a PAL Panasonic HVX200)
    When I import certain of the audio files from the location sound recordist, FCP lists the file as having a TC Rate of 30fps -- and puts a greenbar over my audio track in the 25fps timeline. the audio folks were not TC locked to the camera, so I'm in the midst of doing a manual post-sync (yeah, yeah) of all of these files and Merging them into new Master Clips (1V+6A) for editing.
    I already learned the great trick from this forum of importing the audio takes folders from each day and then disconnecting them to set them all as dual mono, then reimporting -- makes my Merge clips work the way I had hoped they would.
    But this 30fps/25fps issue is really holding me up. This phenomena of tracks mysteriously being picked as having a TC Rate of 30 is rare, like 50 of the 400 audio files, but I can find no way within FCP to correct this setting nor any indication why these files were chosen.
    I can't change the TC from 30-25 when a clip is online or offline -- I get the message "The media of one or more selected clips does not support the chosen timecode rate of 25, and are left untouched."
    Any help will be wildly appreciated -- I am eager to complete this sync project and get cutting!
    matt

    I got help for this issue over at CreativeCow's FCP pages -- it turns out, all I had to do was open a new project using an easy setting and project setting for vanilla PAL 25 fps SD stuff. All of the audio was correctly brought in -- then I disconnected all of the clips, made them dual mono, reconnected them, and copied them over to my old gristly project folder.
    Now I can marry these dual mono 25fps files to the video files without having FCP incorrectly compensate for "30fps" by speeding these clips up slightly, so things stay in sync.

  • Max Bit Rate of Audio and Video supported on iPod?

    Hey
    I've been having issues putting certain videos on my ipod... I've made sure the video bit rate is under the max.
    However, I'm not sure... does the max bit rate of the audio played during videos have to be under 160 for the acc audio?
    I have it at 192... which has worked with other videos, but not some.
    If this is true, let me know. Thanks
    n

    Yes, but it's vague. Is it:
    Mpeg4
    2.5mbps Video Max
    160kbps Audio Max
    They're doing weird things with semi colons, I don't know which format it belongs to.

  • Best Bit Rate for Better sound

    I’m new to the iTunes/iPod thing. A friend told me that he re-sets the bit rate from the default of 128 kpbs to the top of 320 kbps for better quality. [He plays everything off of his computer which is wired to speakers throughout his house and does not travel or drive much so hardly uses his iPod.] I played around a tad with the various rates on the same album and found that a fairly short one used 34.9 MB at 128 kbps, 52.1 MB at 192 kbps, 60.8 MB at 224 kbps and 86.6 MB at 340 kbps. Another friend told me that he noticed a big difference when he played a song off his iPod through his several thousand dollar system if it was imported at 128 kbps. While hard disc space is cheap and I would simply opt for the higher quality setting, the iPods are not so big when one almost triples the file size.
    I tried to figure out what the max bit rates in the CDs are so that could guide the max import rate, but I could not and that question may make no sense at all anyway.
    What is the max that a human can notice the difference at and what have folks found to be the best balance between sound quality and storage space?
    Thanks for your help.

    Monty, this is really going to be up to your ears to decide. All I can tell you is my experience during the 2+ years of owning an iPod. I initially thought AAC @ 128 was satisfactory. I then started experimenting with various bitrates, but kept the AAC format. I decided that 192 was a discernible improvement over the 128. Not to go into a lot of detail, but I, quite by accident, had one album download at 256 & thought, "Wow, this is unbelievably better sound, even over inexpensive computer speakers." At that point, I started importing everything in AAC @ 256 VBR which I feel is pretty darn close to CD quality sound. I have a 60GB iPod that I'm willing to sacrifice some capacity in order to ensure the best audio quality I can. This is also why I do not buy frequently from the iTunes store as I do not feel the 128 downloads are the best quality. I buy & my own CD's, now, to insure good quality. I will by the occasional song from the store when I do not care to buy the whole CD. Hope this helps!

  • Bit rate for all computer?

    Hi all,
    I'm burning a DVD in DVDSP 4, I burned and tried it in my MacBook Pro and on normal DVD player and It works perfect, the problem comes when I play it on some not so new PCs, in one of them the buttons (text and silver frame) in the menu seem to repeat in different positions, and in the other computer it plays fine but the audio doesn't work and sounds kind of static... does it have something to do with the encoding bit rate in DVDSP? maybe in Compressor??
    HDV material / compressed with DVD best 90
    SD DVD/PAL
    Bit rate in DVDSP 5.0 Mbps
    Max Bit rate 6.2
    Appreciate your help!
    Javier

    Which Windows program was used to play the DVDs? Hopefully not Windows Media Player.

  • 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

  • Sample/bit rate for Garage Band '08

    Hello, I don't have a Mac yet, but am going to get the mini soon and do some acoustic/keyboard stuff in Garage Band to get back into recording. What is the sample and bit rate for the new version? I had read that older versions were 16?
    Thanks.

    The sample rate is fixed at 44.1kHz. The bit depth (audio resolution) is selectable at either 16 bits or 24 bits.

  • Target & Max Bit Rate - A Little confusing Need file to be 15 GB Blu-Ray Help????

    I have a 2 and a half hour project on PPro CS 5.5 that I want to encode in H.264 Blu-Ray.  I want to get it to 15 GB.
    What woud be the best settings to do so?
    The Target Bit Rate and Max Bit Rate have a lot to do with it, but I am a little confused on what each of them really do. 
    I just want to get it to 15 GB and make sure the Estimated file size somewhat accurate.
    Is 15 GB too big for a Blu-Ray?
    Thanks in advance

    Hi Jeff,
    I just started to build just my menus with my QT files inside of them as a "Build to Folder."
    I think I know why it's saying 7.1 GB used.
    Since the menus in Encore stop and loop after 30 seconds, I did not like that.
    I like to play a full song on each menu and then when the song ends, it starts again. If I did that on a standard 30 second menu in Encore, the song would stop every 30 seconds and start again. This was not acceptable to me.
    This does not happen in DVD Studio Pro. In DVD Studio Pro, I can put in a full song with Videos in Video Zones, change the loop time to the length of that song, and the menu would play that song, and loop again when it was over. 
    I wanted to do this in Encore, so I had to make the menus a little longer than the song I wanted to put in them. I did that.
    1) I went into After Effects with the background of the menu I wanted to use.
    2) It comes in as a .psd file.
    3) I then stretched it out to a length a little longer than the song. (For exaample, I'm using a song that is 4 minutes and 50 seconds, so I stretched out the background of that menu to 5 Minutes.)
    4) I then rendered out that newly made 5 minute menu out of After Effects, using H.264 1440 x 1080i, 29.97 High Quality.
    5) I then brought that newly made 5 minute background back into Encore and placed it over the original 30 second background in Encore.
    6) Now the song and the videos inside the "Video Drop Zones" will loop until the song is over, stop, then the song will start again and the videos keep on looping. Just like in DVD Studio Pro
    For this particular job I did this 6 times (1 for each sub-menu) depending on the length of the song I am using for each menu.
    1) The first sub-menu is a 5 minute menu which, when rendered in After Effects, came out to be 1.5 GB Big
    2) The second menu is a 4 minute menu which came out to be 1.2 GB
    3) The third is a 4 and a half minute menu which is 1.35 GB
    4) The fourth is a 3 and a half minute menu which is 1.05 GB
    5) The fifth menu is another 4 minute menu which is 1.2.GB
    6) The sixth menu is a 7 minute menu which is 2.1 GB.
    When you add them up it actually comes out to be 8.4 GB just the menus without any videos in them.
    So Encore has already compressed them down a little.
    It's not the videos that are taking up much space, but these menus.
    Since I am building my job in Encore to a folder, I want to see what the actual size comes out to be after it's compressd. This will give me an idea of how big I can make my 2 and a half hour wedding. The Target and Max Bit rate.
    I hope that sheds some light on why Encore is saying that the menus and QT files are taking up 7.1 GB already. 
    I wish there was another way that I can have my menus play for the length of any song without having to go into After Effects and stretch each menu to accomodate the length of a particular song. This takes up a lot of space, but it's the way I like to make my menus.
    Thanks again

  • Suggestions for bit rate for books on cd

    Hi
    I'm trying to clear some room on my ipod. Thus far I've been importing everything at 192. I'm hoping to reimport some of the books on cd that I've put on and would like some suggestions as to how low of a bit rate I can use without affecting sound quality too much (I tried 96 and really couldn't tell the difference).
    Thanks
    Evelyn

    Hi, Evelyn.
    For spoken word recordings, 32 kbps is generally considered an acceptable setting.
    And, for what it's worth, that's the Bit Rate for Audiobooks purchased from the iTunes Store.
    EDIT: You may also want to have a look at these suggestions: Link

  • Optimal bit rate for videos?

    I've used 512 kbps bit rate for my videos, their size was really good (low) but the quality was just too poor...
    What do you think the optimal bit rate would be for videos? (A cartoon show, actually)
    Thanks.

    I use about 1000

  • Optimal Audio Sample/ Bit Rate for DVD?

    In using recorded material to add to DVDs for family and friends, that is, non-commercial, what is recommended formatting for the audio file? Soundbooth seems to default to 48000 Sample Rate/32 Bit but if I use that am I achieving anything over a simple 44100 Sample Rate/16 bit, since the human ear cannot detect above 20000Hz? I want the DVDs to sound as good as possible in STEREO.I don't want to cross-post, so sorry if this is wrong forum.
    Thanks...

    I'm not positive about this, but I think they used 48KHz simply because most professional audio/video gear uses that same sample rate. This makes it easier to tramsfer audio from DV, DAT, etc. without the need for resampling.
    As for why 48 in the first place? This has to do with the Nyquist limit... and that's way too deep for this thread!
    Higher bit depth is another thing all together: This represents the number of possible volume levels (dynamic range) of each sample. 16 bit has 65535 levels which is a dynamic range of 96 dB. This is fine for final delivery -- assuming that the audio was well-mastered at an appropriate volume level.
    During recording and editing, however, where it is likely that adjustments to dynamics (compression, expansion, noise gating, fading) and effects will be applied, it is best to use a higher bit depth so that less information is lost (quantized) on successive transformations of the audio. It also will keep broadband noise from creeping in when the audio is amplified.
    For example, if you have audio recorded in 16 bit and then you amplify it to be 20 dB louder, your dynamic range has decreased to 76 dB and the noise floor has been raised -- meaning there is a constant whitenoise "hiss" in the background.
    32 bit audio is different. The dynamic range is sufficient enough so that moderately large amplification will not neccessarily result in audible background noise.
    The 32 bit audio is then downsampled during mastering to 16 bit for final delivery (often with aid dithering, noise shaping, etc. to avoid distortion and give the "illusion" of greater dynamic range)
    I do agree that 48 KHz is a little bit silly for DVD when the audio is AC3 compressed anyway. I am fairly certain that none of these ultrasonic frequencies will survive AC3 encoding -- even at high rates.

  • The best Bit rate for a 1 hour film

    Hi all
    Just a quick question does anyone know the best bit rate to use to compress a 1 hour film. I want the best quality possible
    Any advice would be gratfully recieved
    Thanks

    If you're using Compressor and it's a one hour encode then use the CBR setting with a bit rate of 6 or 6.5. Also encode your audio to the industry standard .ac3 file format. The combination of audio and video bitrate is always a compromise between quality and having consumer DVD players stalling or choking because the combined birate is too high.
    However, the media content you're encoding will always determine how you should encode: video with lots of fast action needs the VBR setting, whereas the CBR setting can be used when there is little action. But generally, the CBR setting in Compressor will do an okay job with project durations of one hour or less, regardless of the action in your video.
    Hope this helps.

  • Best bit rate for blu rays with Toast 11

    I'm burning a ProRes422 (uncompressed @ 18GB) movie to blu-ray using Toast 11 Titanium. The maximum bit rate is 9.0 Mbps. Is this sufficient? It seems very low...
    Compressor has never worked properly with burning a blu-ray (I know there are more custom settings). I would use this but have had no luck, the blu-ray never burns properly only had luck with Toast.

    Thanks for the info, somehow I've had to pay extra for the blu-ray plug in to burn a blu-ray at 26Mbps.
    Now I need to figure out why the audio now is 'cracking' on the deeper parts of the soundtrack. The audio is set to PCM 96kHz 24 bit just like the original Pro Res file. In the original it does not 'peak' or 'distort' on the deeper parts of the soundtrack when playing in Quicktime, not sure what is happening to the audio after being burned to blu-ray. I might have to post in Soundtrack to get some feedback, any suggestions?

  • Boosting Bit Rate for Higher Quality

    In Two Pass VBR Best DVD (bit rate defaults to 6.2mbps), if I pump up the bit rate to 9mpbs or higher, will my DVD quality increase? File size is not an issue -- it's a 15-20 minute video.
    David A.

    In theory, yes.
    However - +and this is key+ - increasing the bit rate past a certain point will reduce compatibility with many set-top players. For the most part, so long as you're using Dolby Digital audio, you can make due with increasing the average to, say, 6.5 mbps. I personally would not advise going higher than 6.5 mbps unless you're only using the DVD for playback on systems you know you can control (your home or you mac).
    Also, there is a certain point of diminishing returns with encoding. The 90 preset (6.2 & 7.7) is already at the high end of things.
