How do you know the bit rate of a video clip?

I have video clips from my video camera recorded in MPEG 2, PAL standard definition 720x576. 2 questions:
1. How can I find out what bit rate the video is recorded at?
2. Knowing this, can I in PProCS4 encode this for DVD without any transcoding (assuming, of course, no effects or fades etc have been added)?
I like to keep the coding the same, to avoid the quality loss of transcoding to a different bit rate.
I use 256 kb/s audio in MPEG 1 layer 2 (pretty much standard DVD format).
Any info appreciated.

In Ulead Mediastudio Pro, you can see the data rate of the video, and also in DVD Movie Factory select "do not convert..." etc, where un-edited clips are not transcoded, to give maximum picture quality. I dropped MSP, as Corel (having taken over Ulead) has, sadly' dropped the product, so I bought PProCS4 hoping it would be at least as capable. Alas. Having said that, in most respects PPro is as good or better than MSP, and runs fine on Vista and Win7 beta (which I am using now), so I am still happy I get PPro.

How can I reduce the bit rate of songs in my Music Library to enable me to

At the moment i can only fit about 1300 songs on my iphone and also have used up half the space on my 120gb Classic with 7000 songs which is a lot less than what i was told would fit on. so............
How can I reduce the bit rate of songs in my Music Library to enable me to fit more songs onto my iPhone or iPod Classic.. and what is the minimum rate that i should stick to in order to retain good sound quality.

For CDs you import in the future, change the Import settings in the iTunes -> General preferences.
As to what will be a good bit rate, that's going to be up to you and what quality you find acceptable, but many people find that 128 kbps AAC is the optimum balance between small file size and quality.

How do you know the best iMac display size

how do you know the best iMac display size
Only on them fits in the screen window and that makes the font so tiny. The others are too wide or too tall. I usually view at 150 - 200% for vision issues.

You say it's better to do the Media Browser? I'm fairly new to movie, dvd and garage band. How would I go about using the Media Browser instead of straight to iDVD?
Select Your project - go up to Share - Share to Media Browser and as Large (Not HD)
In iDVD select a nice theme - click on Media button - click on Movie - Select Your movie.
NOW - Save as a DiskImage - and test this before burning DVDs - if this Plays OK then either burn the Image by using Disk Util tool (and set down burn-speed to x4) - or burn via iDVD (will take more time)
I want to keep as much quality as I can.
Then don't use iMovie'08 or 09 or 11 - as they all discard every second line resulting in less quality on the DVD. I use iMovie HD6 or FinalCut any version.
Also...I tried to split my project in iMovie...but couldn't find a way. I wound up just making a copy and then deleting out a handful of scenes from the copy...I still have the original at 4:12hrs. Is there a way in iMovie to split a project?
I would make a copy and cut away a bit from the end - calling this Part 1 and from start of the other copy Part 2.
OR - there are other programs that can squees in more to a DVD e.g. Roxio Toast™ - BUT this has two cons.
• It costs - to me it was well spent mony as it can so much more e.g. back engineer a DVD to an editable form
• Squeesing in more on a DVD - costs in QUALITY - and as You want as much as it can be - then 90 minuts portions encoded with Pro-Quality encoding and full quality interlasced material from a video-editor that delivers this is the way to get 100% of what DVDs can do.
DVD is as standard only SD-Video - HD not possibly. Then You need Blu-Ray. (also Roxio Toast™)

How do you know the version of a JAR file ?

how do you know the version of a JAR file ?
is it what is written on MANIFEST.MF ?
for example i have a JAR file
whose MANIFEST.MF has this
Manifest-Version: 1.0
Created-By: Ant 1.4.1so, whats the version of this JAR ? 1.0 ?

anyway, that was JSTL..jar.
Now, come to another JAR file....
whose MANIFEST.MF has......
Manifest-Version: 1.0
Created-By: Apache Ant 1.5.1
Extension-Name: Struts Framework
Specification-Title: Struts Framework
Specification-Vendor: Apache Software Foundation
Specification-Version: 1.1
Implementation-Title: Struts Framework
Implementation-Vendor: Apache Software Foundation
Implementation-Vendor-Id: org.apache
Implementation-Version: 1.1
Class-Path: commons-beanutils.jar commons-collections.jar commons-dig
ester.jar commons-logging.jar commons-validator.jar jakarta-oro.jar s
truts-legacy.jarso, How do you believe whats the version now ? do u go with the comment "Manifest-Version: 1.0" or "Specification-Version: 1.1" ?
definitely, you would go with the "Specification-Version: 1.1" and declare this JAR as STRUTS 1.1
hmmm, so, if nothing is mentioned like above should we follow the MANIFEST version as the JSTL version ? in my earlier example i did not find any comment on ""Specification-Version" ......so , if anybody gives me that JAR , how do i decide whether its 1.0 specification or 1.1 specifucation compliant ?
can you tell whats the JSTL version of my earler example JAR file ?

How do you convert the audio from a mpeg4 video file to mp3?

Probably the easiest way to do this is to download a free media convertor. Most will be able to convert video into audio files.

How do I change the bit rate for dls?? How times can I download one song??

I'm new to iTunes. I already downloaded 3 songs when I realized that the default bit rate is 128Kbps. I tried changing the bit rate to 192Kbps with a (Variable Bit Rate) checked.....unfortunately when I downloaded the next 2 songs the bit rate turned out to be the same.
Do I have to restart Windows or iTunes before downloading again?
And now that I have 5 songs with a lower br than I wanted... in order for me to have(download) the song at the higher bit rate...Is it possible to download one song more than once?
Thanx.

You have no choice as to bit rate when purchasing from the iTunes Music Store. The official bit rate of all tracks there is 128 kbps (a very few have been reported to be at higher rates, but that's not a choice you can make, it's how the track was encoded by the record company). The setting in the iTunes Importing preference is for tracks you import from CDs only and has no effect on iTMS purchases.
Is it possible to download one song more than once?
No. Except in extraordinary circumstances, the iTMS allows only one download per purchase.

How do you know the object is from another database through db link

I have a table named a2z_people. I searched dba_objects, I found this is a public synonym.
How can I know the real table name in the another database. Where is this table come from? In another words, what's the source database?
Thanks!

In DBA_SYNONYMS, there is a DB_LINK column that names the database link being used (assuming the real object is on a remote database). Is that what you're looking for?

How do you change the speed of a detached audio clip?

I have a piece of detached audio. Video Frame rate is 23.98. The piece of Video above it is Video Frame Rate 24.
How do I change the speed of this detached audio clip?

Nope, the Automatic Speed did not work. I exported the XML, and then ran it through X2Pro to try and get my AAF, and it still spits out conform warnings/errors on those same spots. Automatic Speed apparently did nothing helpful to my situation. (Can Anyone explain Automatic Speed?)
Will have to try going through Cinema Tools per the similar issues noted in this conversation: http://forums.creativecow.net/thread/344/28007
Curious to see what FCPX would do with this media, importing the 24p file to a 25 Project cause a noticeable shift in both time and pitch.
I imported the time coded audio separately, and played it against the obviously speed and pitched changed video with embedded audio. The files did not sync.
The audio remained in time and pitch, while the video didn't. So the audio tc doesn't seem to effect playback in FCPX, but video definitely does, and it seems rather buggy.
So, if your video is 24.0 and your audio is 23.98 and you are in a 23.98 timeline, FCPX might be changing the speed of the video without really reporting it. Resetting speed doesn't do anything, hitting "automatic speed" screws it up a bit more (it goes the wrong way). Changing the speed to something like 96% (FCPX reports 96% but I know it's really ((24000/1001)/25) which is just short of 96%. Turning off the "preserve pitch" checkbox actually pitched the audio back to normal.
I didn't create the 24.0 vs 23.9 media that you have, but perhaps you are having similar issues, or a different combination/permutation therein.
But to answer your question, the time coded audio was not changed, only embedded audio.
and
But here some notes which makes things hopefully clearer.
Resampling and changing playback speed are two totally different things.
Samplerate for audio is the same as fps for video (not dpi for video) so let's call it sps.
You can record audio at any sampling rate. But let's take 48 kHz and 32 kHz here.
Record 60 seconds. Once recorded both files as stand alone files will play 60 seconds.
But forced to play back in a NLE timeline with a fixed sps of 48 the first file will playback correctly. The second one will play at 2/3 of the time (32/48). The other way round the 48 sps file will play longer in a 32 sps timeline.
Now for those poor guys who have to work with NTSC:
A real world second is not a second in NTSC video world. Its 1001/1000 seconds.
So selecting a 48k sps audio preset in a timeline preset means that a real world audio of 60 seconds is only 1000/1001x60. That means that those 60 seconds are only 59.94 seconds long. Its too short.
One way - if you stay strictly in NTSC - is to record audio with 48048 Hz. This way a real world 1 second audio will match a 1 second NTSC video.
Next option with BWAVE files is to change the playback settings in the BEXT header of the file. This won't resample the file!!!
Now about the TC. BWAVE doesn't have a TC in a way you're used when handling video. It has a timestamp in the header. This timestamp contains the Samples after Midnight. Based on that the NLE will convert this to TC which can be displayed. So in NTSC world this might give a wrong interpretation.
For example if you have a "Start TC" of 00:10:00:00 (thats what you see on your audio recorder) it means that using 48kHz the timestamp is at 600x48,000 = 28,800,000 samples. Since the real sampling rate in the timeline though is 48048 Hz you have to divide the source stamp by this number. This results in 9.99000999000999 minutes. So for a 23.976 fps project this is a TC of 00:09:59:10.
So setting the Bext header and/or iXML chunk to the correct playback speed will keep everything intact. Again this is without resampling!
Using an AIFF there aren't these options.
So you can edit all the stuff without resampling when using BWAVE. But resampling will happen when you export a final movie.

Can I tweak the bit rate for iPod video?

I am starting to produce quite a bit of iPod video for podcasting. Some of our newer pieces are up to 2 hours long and I want to cut the bit rate back so that the files aren't so large. There does not seem to be a way to tweak the m4v parameters in Final Cut Pro or Quicktime Pro. I was able to make an mp4 video file with what a I wanted. It worked in iTunes but the iPod would not recognize it. Is there anyway to tweak the bitrate when making a video for iPod?

Is there anyway to tweak the bitrate when making a video for iPod?To exercise the greatest amount of control, use MPEG Streamclip (free). The MPEG-4 iPod presets can be user modified to limit data rates as desired.
I was able to make an mp4 video file with what a I wanted. It worked in iTunes but the iPod would not recognize it.The "Movie to MPEG-4" exports are limited to the 320 x 240 "Baseline" profile (up to v1.3).
There does not seem to be a way to tweak the m4v parameters in Final Cut Pro or Quicktime Pro.The "Movie to iPod" export is adaptively pre-set for maximum "LC" (640 x 480) and "Baseline" (320 x 240) data rates. There are no manual adjustments.

How do I reduce the bit rate for existing songs

Some of the songs are too large. How can I reduce the file size of selected songs? Thanks.

Hi,
You can do it by converting your file either with a lower bit rate or using an another compression algorithm. Be aware taugh that by doing so, you will loss audio quality. The best way is to restart, if possible, from your original files with your new importing settings.
To change your importing settings, go in the iTunes preferences, in the Advanced tab and then in the Importing tab and set the compressing algortihm and bit rate. AAC encoder is the algorith that will gives you the better compressing ratio.
Then, you you can either chose to reimport from your original CD (iTunes will ask you to replace the previously imported files) or select from the advanced menu the converting selection.

How do you know the audio level of a keyframes

I'm varying the audio levels of clips on the timeline by creating keyframes using the pen tool. I create four points:
1) -inf = beginning of fade-in
2) -5dB = end of fade-in
3) -5db = beginning of fade-out
4) -inf = end of fade-out
But when I'm going back to adjust points, how do I know what level they're at already without having to drag them away from their home position and then back?
Scrolling over them with the mouse (and not clicking) just gives me a crosshair and no info.
I want to make sure that points 2&3 are at the same level, so I can just move the envelope region between them up and down to change the volume. Any quick way to do this to speed up my process?

Specifically to address this point: if you mouse over the audio levels' rubber band segment BETWEEN your points 2) and 3) until the cursor changes to an up/down adjustment arrow ⬍, and move it up/down, it will adjust BOTH the levels at 2) and 3), maintaining the relative difference between them (or, if points 2) and 3) start at the same level, this adjustment will keep them equal as you drag them both up/down together in one action.)
As usual, much easier to DO it, rather than describe it!

How do you set the burn rate?

I have been told that best results are attained when DVDs are burned at a slow rate, such as 4X. I have no idea of the rate of my burns, and I 'm wondering how I can set the rate at 4X. Is the burn rate manipulated thru DVD Studio Pro, or is it simply determined by the balnk media you insert? For example: does an 8X disc automatically burn at 8X, and a 4X disc automatically burn at 4X?
Thanks, Bob

The burn rate cannot be higher than what the drive is rated for, or the speed the disc is rated for, whichever is lower. So if you have a 2x burner (most likely considering the age of your computer), then that is the maximum speed you can burn at regardless of the speed of the disc media (which could be 16x).
Toast is software. So you would not use it "instead of" your Pioneer burner. You would use it with your Pioneer burner.

How do I reduce the bit rate when listening to iTunes preview of songs ? It is eating up my bandwidth

I like to listen to music previews on my iphone before I decide to buy. But this is eating up my bandwidth. Even the previews are at 256 kbps. This is 4 times higher than Amazon which is 64 kbps. Is there any way to set my access to a lower bit rate, or adjust it to mono or anything ? The bandwidth cost is killing me. Thanks in advance.

How do you change Audio Bit Rate?

Hello. I need to export Mpeg Layer 2 audio with 8 bit sample rate. I can't find any place to change it down from 16.
Help!
Thanks, Chris

No worries. I checked it out. The file I output has to be Mpeg Layer 2 audio (plus it has video attached, It's an Mpeg video file with Mpeg Layer 2 audio).
I only saw .aiff, .mp3, .wav and .mov as export options from Audition... but I could make them 8 bit. I know 8 bit is becoming obsolete, but I wish there was the option within Premiere.

How do you know the true age of your ipod classic..

how can i find out the true age of the ipod classic.. i know its a newer version.. but how do i know if it was sitting on a shelf forever or brand new from apple...

You should see it in part of the description once the divice is connected to the computer through a usb cable. Or you could look at the number by going on setting on your ipod touch then go to general then from there go on about scroll down until you see serial number and ther it is.
