Multi Track settings (Sample Rate and Bit Rate)

I'm setting up my multi-track in 5.5 as 44100 16 bit, but when I create it...it's saying its 44100 32 bit (at the bottom of the multi-track). Is there a way I can change this setting? I've explored the preferences all day long and still can't find any answers.
Thanks

I guess the answer to this question relies on someone having an external digital amp/decoder/processor that can display the source sample rate and bit depth during playback, together with some suitable 'demo' files.

What are the best data and bit rate setting for uploading from final cut express to Youtube?

Can anyone suggest the best data rate and bit rate presets for uploading footage from final cut express 4 to Youtube? What settings will provide the best resolution, quality, and match the current youtube requirements?
Thank you in advance for your help,
Susan Kayne

It depends on whether you are using aspect ratios of 4:3 or 16:9.
Below is some simple guidance that will provide good quality with reasonably small file sizes.
The first part is for 4:3 video:-
1. File>Export Using QT Conversion.
2. The "Format" window should say, "QT Movie".
3. In "Use" select "LAN/Intranet" from the dropdown menu.
4. Click "Save" and when it has finished encoding, upload it to YouTube.
If you are making 16:9 video (Standard or High Definition) do steps 1 to 3 above.
Then when you have selected "LAN/Intranet" press the "Options" button and in the new
window that opens press the "Size" button and change the "640x480" to "853x480"
To do this you will have to click on the 640x480 and a dropdown menu appears.
Select "Custom" from the bottom of the menu and in the window that opens
you will see 2 boxes.
Put 853 in the first box and 480 in the second.
Click OK.
Then Save it.

Maximum audio sample rate and bit depth question

Anyone worked out what the maximum sample rates and bit depths AppleTV can output are?
I'm digitising some old LPs and while I suspect I can get away with 48kHz sample rate and 16 bit depth, I'm not sure about 96kHz sample rate or 24bit resolution.
If I import recordings as AIFFs or WAVs to iTunes it shows the recording parameters in iTunes, but my old Yamaha processor which accepts PCM doesn't show the source data values, though I know it can handle 96kHz 24bit from DVD audio.
It takes no more time recording at any available sample rates or bit depths, so I might as well maximise an album's recording quality for archiving to DVD/posterity as I only want to do each LP once!
If AppleTV downsamples however there wouldn't be much point streaming higher rates.
I wonder how many people out there stream uncompressed audio to AppleTV? With external drives which will hold several hundred uncompressed CD albums is there any good reason not to these days when you are playing back via your hi-fi? (I confess most of my music is in MP3 format just because i haven't got round to ripping again uncompressed for AppleTV).
No doubt there'll be a deluge of comments saying that recording LPs at high quality settings is a waste of time, but some of us still prefer the sound of vinyl over CD...

How to resolve audio sampling and bit rate differences before sound mix

I'm editing a project where an additional recorder (Zoom H4n) was used and synched to the camcorder track with Plural Eyes. Some of the sampling and bit rates don't match within the Plural Eyes synchronized clips and I need to send this out for a sound mix. Could I use Compressor to transcode the audio? Would I have to go back to my original separate tracks, transcode in Compressor and then re-synch using Plural Eyes? Next time ProRes from the beginning -
but if there's an easier fix for my current problem it would be much appreciated.

Thanks Michael -- you've helped me with the project before (back in May of this year).
I started this project as a newby back in 2010 and was a bit overwhelmed (i.e. just happy to get everything into FCP and be able to edit.)
I'll try the media manage solution, but if that doesn't work I think I'll live with the one-frame drift. I'm assuming
the only other alternative would be to go back to all the original video and audio files; transcode using Compressor, and then re-synch with Plural Eyes and go back in to match up the edits?
Thanks to your continuing help, I should know how to set things up correctly from the get go for the next one!

Bit Depth and Bit Rate

I have a pre recorded mp3 VO. I placed it into a track bed in GB. Clients wants a compressed audio file with bit depth: 16 bit and bitrate: 128kps max, but recommends 96kbps. If I need to adjust the bit depth and bite rate, can I do it in GB? and if so, where? Thanks for any help.

Please be aware that Bit Depth and Bit Rate are two completely different things!
They belong to a group of buzz words that belong to Digital Audio and that is the field we are dealing with when using GarageBand or any other DAW. Some of those terms pop up even in iTunes.
Digital Audio
To better understand what they are and what they mean, here is a little background information.
Whenever dealing with Digital Audio, you have to be aware of two steps, that convert an analog audio signal into a digital audio signal. These magic black boxes are called ADC (Analog Digital Converter) and “on the way back”, DAC (Digital Analog Converter).
Step One: Sampling
The analog audio (in the form of an electric signal like from an electric guitar) is represented by a waveform. The electric signal (voltage) changes up and down in a specific form that represents the “sound” of the audio signal. While the audio signal is “playing”, the converter measure the voltage every now and then. These are like “snapshots” or samples, taken at a specific time. These specific time intervals are determined by a “Rate”, it tells you how often per seconds something happens. The unit is Hertz [Hz] defined as “how often per seconds” or “1/s”. A Sample Rate of 48kHz means that the converter takes 48,000 Samples per second.
Step Two: Quantize (or digitize)
All these Samples are still analog, for example, 1.6Volt, -0.3Volt, etc. But this analog value now has to be converted into a digital form of 1s and 0s.This is done similar to quantizing a note in GarageBand. The value (i.e. the note) cannot have any position, it has to be placed on a grid with specific values (i.e. 1/16 notes). The converter does a similar thing. It provides a grid of available numbers that the original measured Sample has to be rounded to (like when a note get shifted in GarageBand by the quantize command). This grid, the amount of available numbers, is called the Bit Depth. Other terms like Resolution or Sample Size are also used. A Bit Depth of 16bit allows for 65,535 possible values.
So the two parameters that describe the quality of an Digital Audio Signal are the Sample Rate (“how often”) and the Bit Depth (“how fine of a resolution”). The very simplified rule of thumb is, the higher the Sample Rate, the higher the possible frequency, and the higher the Bit Depth, the higher the possible dynamic.
Uncompressed Digital Audio vs. Compressed Digital Audio
So far I haven’t mentioned the “Bit Rate” yet. There is a simple formula that describes the Bit Rate as the product of Sampel Rate and Bit Depth: Sample Rate * Bit Depth = Bit Rate. However, Bit Depth and how it is used (and often misused and misunderstood) has to do with Compressed Digital Audio.
Compressed Digital Audio
First of all, this has nothing to do with a compressor plugin that you use in GarageBand. When talking about compressed digital audio, we talk about data compression. This is a special form how to encode data to make the size of the data set smaller. This is the fascinating field of “perceptual coding” that uses psychoacoustic models to achieve that data compression. Some smart scientists found out that you can throw away some data in a digital audio signal and you wouldn’t even notice it, the audio would still sound the same (or almost the same). This is similar to a movie set. If you shoot a scene on a street, then you only need the facade of the buildings and not necessary the whole building.
Although the Sample Rate is also a parameter of uncompressed digital audio, the Bit Depth is not. Instead, here is the Bit Rate used. The Bit Rate tells the encoder the maximum amount of bits it can produce per second. This determines how much data it has to throw away in order to stay inside that limit. An mp3 file (which is a compressed audio format) with a Bit Rate of 128kbit/s delivers a decent audio quality. Raising the Bit Rate to 256bit/s would increase the sound quality. AAC (which is technically an mp4 format) uses a better encoding algorithm. If this encoder is set to 128kbit/s, it produces a better audio quality because it is smarter to know which bits to throw away and which one to keep.
Conclusion
Whenever you are dealing with uncompressed audio (aiff, wav), the two quality parameters are Sample Rate [kHz] and Bit Depth [bit] (aka Resolution, aka Bit Size)
Whenever you are dealing with compressed audio (mp3, AAC), the two quality parameters are Sample Rate [kHz] and Bit Rate [kbit/s]
If you look at the Export Dialog Window in GarageBand, you can see that the Quality popup menu is different for mp3/AAC and AIFF. Hopefully you will now understand why.
Hope that helps

What are supported sampling frequency and digitization rates for Zen Micropho

Some MP3's are playing back slowly. It is inconsistent, though, since files with the same digitization rate and sampling frequency will behave differently - some right speed, some slow.
The bulletin board says:
"My tracks don't play at the correct speed e.g. they play too slowly, why?
Chances are they are encoded in an unsupported sampling frequency..."
How do I find out what the supported sampling fequencies and digitization rates are?

Thanks for the info. I guess I was looking for something more specific - the exact bitrates and sample rates that Creative claims to support. Would you know where official and comprehensi've data can be had? There must be a tech spec somewhere.
It is common these days in business to see a recording of, say, a conference call or seminar presentation at 32k bitrate/025Hz, or even 24k bitrate/8000Hz, posted to a company's website for download by those who could not be there, and MP3 players are increasingly used for their replay. Companies use low digitization rates because there is no need for hifi and the files are much smaller: less storage, faster download.
I'd be surprized to think that Creative don't have compatibility with the standard range of rates offered by ubiquitous programs like Audacity and dBpower, the latter being one they themselves recommend!

Common video dimensions and bit rates for dynamic streaming?

I'm going to be converting my videos to flv and am trying to decide what to use for video dimensions and bit rates. Some of my users have slow computers and connections so I'm thinking 150 on the low end.
Is there a common practice? What has worked well for you in the past?

Hello MrWizzer
I am not sure what FMS version you are currently using.
Well, if you look at the sampe vod folder that ships with FMS4.5, it has files encoded @ 150kbps, 500 kbps, 700 kbps, 1000 kbps, 1500 kbps.
I am sure that all of these files stream perfectly fine given the correct bandwidth environment.
Its totally depend upon the FMS hosting service provider depending upon the user base of a particular provider.
You need to judge what kind of BW is available to your viewers and put the files encoded at appropriate bitrates.

MuVo N200: recording fidelity and bit-rate for podcasts

Hi,
My plan is to use my MuVo N200 for recording podcasts--I'm wondering what the fidelity and bit rate is for the line-in recording capability.
Is it 64k bps? Something else?
Any one else using the line in?
Thanks,

Rebate rate and accrual rate

What is the difference between rebate rate and accrual rate in rebate agreements. One example wil be very helpful

Accrual Rate:
You can enter an accrual rate manually in each condition record. The accrual rate should reflect, as accurately as possible, the rate at which the rebate will be calculated at final settlement.
Every time you process a rebate-relevant billing document (an invoice, a credit or debit memo), the system automatically posts an accrual to financial accounting (FI). Within FI, the rebate accrual is posted to two accounts: a sales deduction account and an accrual account. The accrual account is cleared when the rebate agreement is settled with a credit memo.
Rebate Rate:
A price discount that a vendor grants a customer at a later time.
The amount of rebate depends on the invoiced sales that the customer achieves in a specified period and is defined using condition records.

Spot rate and Exchange rate

Dear SDN's
I want to know,
What is spot rate in FI?
What is difference between spot rate and exchange rate?
where we can find this spot rate in R/3?
i am doing report for FI where the client want this spot rate? where the client is not maintaining any practice in R/3 for this spot rate. i would be very grateful for your valuable suggestions.
Good day,
thanks and regards
Arun

Hi
A forward exchange transaction can be regarded as a future spot exchange transaction, because it comprises the future purchase or sales of foreign exchange.
Check the link for more info
http://help.sap.com/saphelp_nw04/helpdata/en/3f/f2fb76a87711d198b00000e8a5999a/frameset.htm
You use spot exchange transactions to buy and sell internationally traded currencies against other currencies. These orders have very short expiry terms. It is a binding agreement for the immediate exchange of foreign exchange. As a rule, the foreign exchange is credited or delivered two days after conclusion of the business transaction.

Difference between Rebate rate and accrual rate

Dear Experts,
Can you explain the difference between Rebate rate and accrual rate in rebate processing ?
If possible, give any example so that it would be easier to understand.
Thnx in advance
regards,
Sagar

Hi Sagar,
I also agree that rebate is an amount which is derived from either sales order or billing doc.
No it's not; only billing documents update rebate agreements.
... two terms i.e. Rebate rate and Accrual Rate maintained in condition records for rebate agreement.
Accrual Rate = The rate used to accrue the value (provision) before settlement takes place.
Rebate rate = The rate used to generate the real credit amount to the customer when settlement takes place.
Usually both rates are set the same but, because if scales are used in the rebate rate, then it is usual to manually set the accrual rate at the expected rebate rate based on the planned sales volume.
If I am not wrong, the condition technique it it the accrual rate which determined not the rebate rate.
Not correct; the condition technique is used to determine both rates in the rebate condition.
Also i tried to create scales for rebate, this can be done with rebate rate and not with accrual rate. Then what is its use.
Scales are used when the amount is paid on a variable rate depending on the total customer consumption. The idea is that the more the customer is purchasing, the more rebate he will receive, also on its previous purchases.
Accrual rate is fixed (no scale).
Hope it helps.

File sizes and bit rate slider

Hi,
I'm having two issues I'm hoping someone can help me with..
1) My file sizes are much bigger than they're apparently supposed to be. A 10 second clip at 720x576 takes up 32 MB. I've tried both quicktime h.264 and various avi codecs with roughly the same results. A larger 3 minute clip takes up over 500 MB. This is at 100% quality setting. I was told that they shouldn't take up more than 10% of that size so I'm not sure what's going on..
2) In order to solve it I've been told to use quicktime h.264 and adjust the bit rate slider to specific values, but PE7 won't give me that option, I can only move the quality slider. Setting that to a low value gives me extremely poor quality video. Using Sorenson codec allows me to set a bit rate, but at the recommended 1800 k/s I still end up with 22 MB for 10 seconds.
These videos were made through stills and transitions.. When I make similar stuff with windows movie maker the files are much smaller so something weird is going on for sure.
Hopefully I'm making a really obvious error that is easy to point out :D

This is for web use, but mind you there are plenty of sites that offer hd video so it's not a particularly high resolution..
I just don't understand why these files are so big considering the maths.
I've had 1800 kbit/s recommended as a decent compression level for web use. That's 225 kbyte/s or roughly 2.5 MB for 10 seconds. Yet as described above the files are 10 times that size. I don't understand why this is when I actually used this exact compression level.
Further, I was only able to specify bitrate compression with the Sorenson codec, not h.264, which is the one I actually want to use (and which I've been told should have adjustable bitrate in PE7 making me doubly confused..)

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.

Rebates- Accrual rate and Rebate Rate

Hi, I am working on Rebate configuartion.
Can any one explian me the difference between Rebate Rate and the Accrual Rate that we provide while creating Rebate agreement.
Regards,
Sunil

Hi,
The rebate rate is the rate at which you have made the agreement with the customer for a specified period.
Accrual is the total rebate need to be provide for the agreemnet period.
