Bit Rate and Encoding

Hey y'all--
I've read all the posts about this, but can someone please give me a simple answer (if one exists)?
When I format (encode) my project, I would like to start with high settings then back-off when I run out of room on the DVD. The media (aside from Menus) is a series of 3min animated films (4 now, more later). My encode settings are as follows:
FIELD ORDER: Auto
MODE: Two Pass VBR
BIT RATE: 5.0
MAX BIT RATE: 7.5
MOTION ESTIMATION: Best
Is this a good place to start or should I up the bit rate settings? I'm just looking for a benchmark.
Thanks in advance.

Did you Google for a bitrate calculator as I suggested?
http://www.videohelp.com/calc.htm
With an audio bitrate of 192kbps (i.e. Dolby Digital encoded by Compressor 2 or A.Pack), it tells me that 90 minutes of video should be encoded at an AVERAGE bitrate of 6.6Mbps to fill a single DVD-R.
If you want, you can do that as a constant bitrate encode of 6.6. You can also do a two-pass VBR encode with average of 6.6 and maximum of (say) 7.5 (because as David points out again, there are issues with high bitrate playback off of DVD-Rs).
If you want to get more on the disc, encoded at a lower average bitrate.
If you want to split it across two discs and encode everything at a high constant bitrate, you can do that too.
If you are going to get this disc REPLICATED and therefore not have the DVD-R playback issues, you can encode all video at 9.5Mbps and fit 40 minutes onto a DVD-5, or 80 minutes onto a DVD-9.
Or you can lower bitrates and resolutions dramatically and fit a lot more onto a single disc.
It completely depends on your project, your delivery requirements, and your quality requirements.

  • "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.

  • Streaming multi bit rate and single bit rate

    I'm trying to simplify my setup.  Sometimes I need to stream multi bit rate and sometimes I need to stream single bit rate.  This is due to the internet connections I'm sending from sometimes have poor upstream and multi-bit rate is too much bandwidth to send... So....  We resort to single bitrate.  As I understand my encoder and server settings are different for each of these...  I created a single and multi-bitrate profile for Adobe Media Encoder.  That was simple enough.  My question/concern is in regards the server settings.  I would like to have a server setting for multi-bitrate and a setting for single bit rate.  My goal is to void making changes  on the server.  I simply want to load the desired Adobe Media Encoder Profile.  So, do I need to create a dedicated event for single bitrate?  Below is the syntax I send to my server from Adobe Live Encoder.  Instead of using 'liveevent' for my event would I just give it a different name?  Does this stand true for my .m3u8 files?  I'm confused to how to name differnet event/streams.... 
    livestream%i?adbe-live-event=liveevent&adbe-record-mode=record

    Hi,
    When you use a setting like: livestream%i?adbe-live-event=liveevent then the encoder expects multibitrate streams (the %i is replaced by a number so the streams published will be livestream1, livestream2 and livestream3). You cannot use the same setting in the encoder for single stream. Instead you'll have to use livestream?adbe-live-event=<event_name>. You could create a new event under the same application.
    Hope this helps. Let me know if you have any other queries.
    Thanks,

  • The selected combination of bit rate and sample rate is not allowed.

    I've always burned my purchased CDs into iTunes using a AAC 320 kbps and 48.000kHz. Now when I select that option in iTunes 9 I'm getting a "The selected combination of bit rate and sample rate is not allowed." pop up screen. So is it impossible to burn my albums in a 320kbps/48.000 AAC format?. I had no problems in previous versions of iTunes using this setting. I guess I might have to switch over using a MP3 import setting instead.

    Audio CDs are encoded with a sample rate of 44.1 kHz. Ripping them at 48 kHz requires resampling and does not improve the quality. Unless you have a special need for 48, use 44.1.

  • How to set the Codec, Frame rate, Bit rate, and Resolution for iMovie 10.0.5

    To upload a video to Vimeo, I need to be able to set the codec, frame rate, bit rate and resolution to make sure the file is compressed to under 500 MB. Where in iMovie 10.0.5 am I given the option to adjust these settings?
    Thank you!

    Another question is in continuous mode, NI DAQmx uses Samples per channel to determine the buffer size. But according to the website you specified, it says if the acquisition is continuous (sample mode on the DAQmx Timing.vi is set to Continuous Samples), NI-DAQmx will allocate a buffer according to the following table. And for sample rate between 100 - 10,000 S/s, the buffer size is 10 kS. So if I set the sample rate to be 5000 S/s, and set the Samples per channel to be 20000, then what exactly the buffer size is? 20 kS or 10 kS?
    Thanks.

  • Export failed to meet required bit rate and color space specs - ProRes 422 to MPEG2

    Using Premiere Pro CC v7 I exported a ProRes 422(HQ) file to MPEG2 and selected the HD 1080p 23.976 preset.  I needed the finished file to have a minimum bit rate of 50Mbps and the color space to be YUV422.  I was way under the minimum bit rate and the color space was incorrect. Can someone please instruct me on how to achieve my desired results. Thanks!

    The source frame rate is 23.976, so I guess I would go with 24p. My intention is to upload the file to a streaming video website. They have their specs laid out for me, I just happen to be new to all of this so I am having a tough time meeting them.
    My question right now is, if i have selected the MXF OP1a XDCAM option with XDCAM 50 NTSC (4:2:2) video codec, will the export be in mpeg2 and what will my bit rate be? I have no way of viewing the bit rate with this configuration.
    Here is a screen grab of their required specs:

  • TS5181 iTunes radio - Bit Rate and recording

    There is an ongoing comparision to Pandora however, I suggest that Pandora offers a better value by far:
    1. iTunes Radio does not state bit-rate
    2. Pandora One is 192kb for $40/yr, with no adds; free Pandora is 64kb and has adds
    3. PandoraJam permits recording to Mac, $15 one-time cost, 192kb unlimited downoads
    4. iTunes Match, at $25/yr, permits saving current and paid misic to iCloud plus no adds, but STILL charges $1.29/song.
    NOTE: I am pro Apple and nearly all my IT devices are Apple however; this is a difficult business case.
    Can anyone tell me why iTunes Radio would be a better deal?

    I'm curious as well what the bit rate is for iTunes Radio and am suprised Apple hasn't published it. 
    Forbes.com is doing a followup story soon which will compare iTunes Radio, Spotify and Pandora that you may want to check out.

    Apple has a history of withholding geek-oriented specs on consumer-oriented products. By their silence I think we can assume that it’s not higher than what Pandora’s max setting offers. And it certainly wouldn’t make sense for the rate to be greater than the 256 kbps of iTunes purchases.
    There’s also the possibility that Apple is offering adaptive rates depending on whether a user is connected over WiFi or cellular.
    I’m working on a story comparing aspects of iTunes Radio, Pandora and Spotify (stay tuned) and I’ll report on whether there’s an audible difference between them.
    Also found a post on Macrumors by someone who did their own "test" yesterday who is suggesting that it is 256 kbps similar to what you get for iTunes purchases.

    Money and "value" aside, I've been listening to iTunes Radio for a day now on my Denon AVR and B &W surround sound system via airplay streaming to my AppleTV and it sounds as good as Pandora One -- and I think the playlist alogorithim is superior to Pandora as I'm hearing a bunch more variety and music I like on a station I created similar to one I have on Pandora.

  • Blu-Ray bit rate (and other questions)

    Hi, just getting ready to try out my new blu-ray burner and I had a couple quick questions regarding outputting via compressor, thanks for any help and advice:
    1) What's the recommended average and max bit rate assuming file size isn't an issue?
    2) Can I put multiple videos on one blu-ray? From what I can tell it's only one per disk...
    3) The blu-ray template wants audio and video from one source, correct? Or can I drop in a quicktime video and a separate audio track? (For instance, I have a surround sound mix that was done elsewhere while the video was edited and output from an Avid)
    4) Will compressor accept Avid DnxHD quicktimes?

    I assume you mean to create a BD with Compressor.
    1. 34mbps, if I remember, is the max. Just let Compressor calculate the average and max. With a good source, an average above 24mbps won't make a difference of quality, in my opinion.
    2. No; you have to have a single movie all assembled in FCP first. But you can use chapter makers to mark multiple original movies.
    3. One source only, correct.
    4. I don't know.

  • Bit rates and battery life

    I have noticed several times that the battery seemed to drain faster than it should. A 20 minute walk while listening to an audio book seemed to drain the battery about 15-20%. Is there an impact of the bit rate to the battery load? If so what is the optimum bit rate?
    Thanks

    Hi John,
    the bit rate does influence battery life insofar that the cpu may have different power consumption if the task takes more calculation power. I have no idea, how strong the bit rate does influence the power consumption in terms of battery time and such.
    also, do you have the play slower feature enabled for your audio book? that might also cost more power.

  • Bit rates, and how plugins affect them

    so my bounce process is, bounce once soft without mastering effects. then bump up volume and add effects. im recording at 24 bits. should i be dithering on the first bounce or the second? which will give me better quality? if i dither the first time and get it down to 16, then bounce again with (i presume) 24 bit effects, will a c.d. take it?

    I'd suggest bouncing your mix without any mastering effects. Once you've got the mix the way you want it, keep that separate.
    Then load your mix in to a separate song file, and apply any effects you want there. Then save that with a separate bounce name.
    Then load one or more of your 'mastered' mixes into WaveBurner, and do your final trims there, and burn your CD. Let WaveBurner take care of dithering and burning. To burn a CD it'll be 16-bit 44.1 kHz
    This way, you're keeping the stages separate, and more easily compare the results you got at each stage.

  • Sample Rate and "Smart Encoding Adjustments"

    Wondering if someone could help me out with this...
    Is there a reason to choose a higher sample rate over a lower one when importing? Does it improve the audio quality? Or should I just put it in the auto setting?
    Also, what does the "smart encoding adjustments" option mean? (In the "custom" settings for mp3 format)
    I'm basically trying to get my music onto my HDD at the top quality possible, so I'm trying to figure all this out.
    Thanks.

    The info below should give you a start on the concepts. Google can find many more facts, opinions, and misconceptions about Lossy vs. Lossless music formats. Way too much information to be listed here. Do several searches with various keywords.
    Song file size is a factor of bit rate and song length. Audio quality is a factor of bit rate and encoding format. AAC and MP3 formats are considered Lossy, as they sample the target music file and reduce the total size with some reduction of audio quality. Lossless files are considered CD replicants as they contain all the digital data on the original audio CD. They can be fairly large in comparison to the traditional Lossy file.
    Encoding a music file into a Lossy compression format will strip details from the file. Transcoding from one Lossy compression format to another Lossy format will compound the loss of details from the file. (eg: transcoding a sound file from: AAC to MP3; or MP3 to AAC). The audio degradation becomes more apparent when transcoding files ripped at lower bit rates (less than 192kbps).
    When you burn an AAC file to CD and then re-rip the CD as AAC or MP3, the sound you end up listening to will have gone through a lossy compression process twice. Those losses can add up, taking what were only mild or even unnoticeable deviations from the original sound after the first phase of compression and making those deviations much more noticeable and objectionable. This is especially true if you try to take music at a low bit rate like 128 kbps (what Apple uses for iTMS) and try to compress back down to the same low bit rate.
    The preferred method is to save all audio "masters" in a Lossless audio format such as Apple Lossless, WAV, AIFF or FLAC (or the original CD), and then transcode directly from the Lossless source file to your preferred Lossy format such as MP3 or AAC. This procedure preserves as much of the original audio signal as possible and prevents the compound loss of audio details from the file.
    The generally accepted theory is that AAC/128 sounds as good as, or better than MP3/160 (and possibly even MP3/192). Transcoding your AACs/MP3s will most likely result in noticeable audio quality degradation. But -- test it out for yourself. If you cannot hear the difference, then it may be acceptable. Bear in mind that any improvements &/or upgrades in equipment (iPods, headphones, your ears, etc.) may uncover the additional audio limitations you created at a later date.

  • Can no longer change bit rate in AAC custom import settings

    I've been re-ripping all my CDs at the new higher bit rate. My import settings were AAC Encoder -- custom, originally set to 256 kbps, VBR, and auto for the other two settings. However, some CDs I wanted at a lower setting, so I would go change the bit rate to either 192 or 224 (just so I'd have more room on my ipod) and there wouldn't be a problem. But now it's stuck -- the pop-up box no longer opens when I choose import settings, AAC Encoder, Custom, so I can't change the bit rate or anything else, and it's stuck on 224 kbps. I can still change bit rate and other settings in the custom menus for MP3, WAV, etc., just not AAC. A repair install of iTunes did not fix the problem.

    Hi, Ed. I am running iTunes 9.0.3.15. When I click custom, the settings description in the details box display what they were before this thing happened = 112 kbps (mono)/224 kbps (stereo), VBR, optimized for MMX/SSE2. The pop-up dialogue box that used to appear (where you could choose the specific bit rate from the drop down menu) does not appear at all.
    However, when I choose anything other than AAC Encoder, and then pick custom, the pop-up box appears and I can choose the bit rate and adjust the other settings as usual. It's just not happening for AAC Encoder anymore. Since the total un-install (following Apple's specified order) and reinstall didn't work, I'm baffled how to fix this .... (If it makes a difference, I changed the bit rate in the custom box while a CD was being burned...Apparently that was stupid, but I had done it previously without incident.) Thanks.

  • When is the h.264 bit rate issue going to be fixed?

    If you export a project in After Effects using the H.264 codec the file you export does not have the correct bitrate. Meaning if you export a video at 1mbps compression rate you will not get a video that has 1mbps bitrate. This has been an issue since day one along with header issues in the .mp4 file. Please do not tell me not to use AE to create H.264, this is what we used and works fine in CS4. The same issues arrises when you use Adobe Media Encoder CS5.
    Does anyone have a solution or anyone from Adobe have any suggestions?

    Thanks but that didn't help.
    I believe I have found out the actual issue. CS5 will not render a project above the lowest bitrate of the source video for H.264. So if you have a video file at 300kbps it cannot be rendered above that point. This is a problem when you understand how bitrates\codecs work. Not all codecs need an extremely high bitrate in order for the quality of the content to look good. We use the TechSmith screen capture codec a lot. This codec is create for screen capturing, it provides a low bitrate file which is small in size and easy to handle. We have been using this combination with the CS package since before it was CS. The videos we procude look great in CS4  but awful in CS5. When using mediainfo to check out a video file compressed in CS5 it gives us a Bit Rate and a Normal Bit Rate. Normal bit rate is what is requested, say 1mbps and the actual Bit Rate is what the source material was.
    In any case the video files look like crap because a 250kbps .mp4 looks awful compaired to a 250kbps video using the TSCC codec. So yeah, not using CS5 and most likely won't be doing any more upgrades in a while. I'm responsible for purchasing over 10 licenses. Just wanted to let Adobe know they won't be getting that money again for a while until they figure out there compression issues.
