Why duel bit rates after importation?

I imported my shared music folder. It shows duel titles & bit rates for SOME songs. (128 & 160)
Should I keep both, or, rid myself of one or the other?

If you have duplicates, I would keep those at the
higher bit rate. There won't be much in it between
128 kbps and 160 kbps but the 160s will be of a
slightly higher quality. It's really up to yourself
but there is no reason to keep both as you are just
using up disc space with duplicates
Thank you!
My thoughts exactly. Needed an expert opinion. Thanks again

  • Video bit rate after conversion

    Hello everyone,
    Im wondering, if i have a file of x format, with 50Mb video bitrate, and I convert it using compresor 4 to ProRess 422, the result will give me a video with .mov extentin with video bitrate around 120 Mb, if I convert it to Proress (LT) it will give a result of around 70Mb video bit rate.
    Will the new outputs have true clean bit rate, I mean the margine btwn 50Mb and 120 or 70, will it be showed , so will the new video show a better result, or it will just show same result at 50Mb. 2nd, in case I reconvert from Proress 422 (LT) (70 Mb) to anyformat (not necessarly using cpmpressor 4) to any format havn video bit rate again 50 Mb, will the output be the same of the original 50Mb that had the x

    If you are concerned about this issue, do your own tests.
    Make a copy of a representative sample of your original material in ProResHQ, one in ProRes422 and one in ProResLT
    Put your original in a ProRes4444 timeline in V1 and one of the copies in V2. Apply the difference matte.
    Do you see anything? Do the same process for all three variants of ProRes.
    Now, convert the material to your delivery format and put it back in the ProRes4444 timeline on V1 and one of the ProRes copies on V2 and apply a difference matte. Again, what do you see?
    If you see a solid screen of black, there is no measurable difference between the files.
    If you do see artifacts, do an A/B comparison on a good grading monitor - sometimes stuff that shows up in the difference matte can not be seen by the eye even in dedicated A/B testing.
    Have fun.

    fwiw - all ProRes varients are 10 bit codecs. They are designed to absorb a great deal of editing/compositing without degrading. This is why you want to get any material that was acquired in a long GOP, compressed format OUT of that format as soon as possible if you will be grading, compositing or doing any work beyond simple cuts.

  • Why no bit-rate control when encoding from Premiere CS4?

    Recently upgraded to CS4 from CS3 on my HP-9300 workstation. When encoding for DVD from the Premiere CS4 timeline I've noticed that there are no options for adjusting bit-rate. This functionality was available for the PC on CS3, why is it missing from CS4? Am I doing something wrong?
    Thanks.

    PC.
    Win 7.
    When you export (File\Export\Multimedia Files) a window appear, and you click on Video (just under your encoding spec.).
    A wider window appears and if you scroll down a bit you'll see your bitrate settings, of course you can modify them.

  • Why doesnt Bit Rate show when you Get Info

    When you downgrade the bit rate of a song in itunes for example, from 320kbps to 128kbps then click get info it will show the bit rate, but if you use your Finder locate the song file and click get info it will be missing
    why is this
    is there a way to make it show?

    You cannot show bit rate using finder. This value is not included in the get info box - only sample rate is shown. You should use iTunes to find the bit rate of the track which you can see in song view if you have added this from view > view options.
    If you want to see in finder, I suggest that you provide feedback to Apple.

  • Variable bit rate on importing bug in iTunes 7.5

    I have tried importing a new CD into iTunes 7.5, installed this week as an update to the previous version.
    Now each track imported comes in at variable bit rates. I cannot seem to stop this. I tried to create a custom import rate without VBR but it ignored it anyway.
    Is there a fix for this? 7.4.x and earlier versions was fine.
    Mark

    Apparently it is related to the new QuickTime AAC encoder.

  • Why are files larger after importing? idvd 08.

    why when i import a 2.38gb file does it say 4.92gb and its too large for project? any answers are greatly appreciated. thank you.

    Material on a DVD must be in a standard format, and video's format is mpeg-2. It sounds like you must have a video in a very compressed format and so iDVD has to uncompress it and change formats (transcoding).
    Really though, what matters is length. iDVD can fit up to 1 hour of material at highest resolution (best performance setting in preferences) and up to 2 hrs maximum (best quality setting). Or you can use the Pro setting, and it will take a bit longer to encode/burn, but the quality should be similar to Best Performance.

  • 1080-60i so why is is 30fps after importing?

    The whole interlaced vs progressive thing is confusing. I have a HF100 1080-60i camcorder (also records 720-30p, though not sure it is true 30p or not). When I import into iMovie as a 1080i file, its shows 1080i-30 in the finder and the .MOV clips also show 30fps. Why not 60i? Is iMovie converting the 1080-60i to 1080-30i? I know iMovie can't do 1080p. Would it be better to create a 720-30p iMovie instead? Looking for the smoothest quality output, which is why I shoot in 60i rather than 30p. Thanks.

    No, don't record in 30p.
    In 30p each "field" (..as Matt has explained; a "field" is half the information that's contained in a single frame..) is more-or-less doubled, or recorded twice. When that reaches iMovie, iMovie plays the video at twice the normal speed! ..because it thinks that there should be two separate or different "fields" in every frame, not the same field twice.
    Record at 60i. That's the "traditional" way to record video. That's compatible with iMovie. 30p is NOT compatible with iMovie.
    Using a p ("progressive") frame rate is intended to simulate film, and to be a cheap way - at 24p - to shoot video and then have it transferred to film for showing in cinemas.
    Avoid anything with p on the end; always shoot at an i frame rate, because that's what iMovie understands.

  • Why 64 bit itunes is important....

    i work in the industry as a service and repair technician. i fix peoples computers everyday.
    the lack of native 64 bit applications is costing me over an hour of lost productivity a day. many 64 bit applications that i have wont put a call to a 32 bit application, nor will that 32 bit application access memory addresses above 4gb which is a real pain when i am really busy and theres no free memory addresses below 6gb.
    this issue not only affects me but my customers also, and to a lesser degree in this case apples reputation. how can i recomend apple products to other people when i can no longer recomend them to myself ?
    i have supported itunes since its release and apple for over 20 years, but the time has come and gone now for apple to come to the party.
    64 bit operating systems have been in the wild now for 8 years, XP64 4 years, vista64 2 years and now win7-64 so there is no reason NOT to have released a 64 bit version of itunes.
    as an example adobe have had requests for a 64 bit pdf reader and flash player dating back to 2001. adobe's reply is 32 bit works; try visiting a flash based site or open a pdf in firefox64, 32 bit code doesnt work. i no longer use adobe products and boot to linux and use an open source version of flash for flash based sites, and i recomend the same for my customers.
    yes i am venting my anger at any company that does not support native 64 bit applications at this such very late date.

  • Bit Rate Issues

    Ok here is the problem, in both H.264 and Mpeg-4 If I set the Bit rate to say 300kbps the end file has a bit rate of 512 kbps with a total bit rate of around 700kbps. Any suggestions or solutions. My audio is set at Liner PCI at 32.kHz 16bit
    its like Quicktime is overriding my bit rate

    Your wondering why you bit rate is 700kbs? Probably because you using PMC for your audio. Try AAC...your audio file will be smaller...Remember you bit rate is your video and audio added together.
    Open you finished video in Quicktime--->Windows-->Show Movies Properties. This will show you the bit rate for the audio and video separately.

  • Import songs at selected bit rate

    i thought when i set the preferance for importing music say at 128 kbs as a mp3 that was how all the songs would be imported.so why do they still import at differant bit rates and how can i get them to 128 kbs?

    I see missing burn settings, too, & I'm getting a message about it each time iTunes is started. I have one (actually more than 1) unburned purchases from Apple Store, which downloaded as protected media (unplayable outside iTunes, even in my registered & paid for version of QuickTime - & that's a first). So, the repair needs to be done, at least temporarily, to burn out the purchases.
    But, after the update the optical devices were no longer in the UI, so, I removed some things, manually, one of which is shown in the iTunes credits section as related to their burning software, at which time the optical drives again seem to be available to me, the owner, if not to iTunes when I authorize it for my usage. Clearly, this is an issue with Windows, DRM or some, other malicious software, otherwise, iTunes' use of MS approved software for burning would be no issue.
    However, the import settings remain. They could be useful if one used iTunes to sync to iPod, I suppose, although other software is also capable of syncing to iPod. Other features of iTunes should also be unaffected, like the radio or podcasts or books or other feeds.
    Browsing the Apple store is almost pointless under these conditions unless one turns on the option to see only DRM free media --- & there is precious little of that. I was actually beginning to use iTunes & the Apple store almost exclusively for that (& considering a Mac laptop) because of that reliability; apparently, my choice to never give up my freedom of choice to one provider is not without wisdom, since we just never really know what to expect.
    Anyway, this looks more & more like some server side mal-usage of DRM.

  • Imported .m2v bit rates in Encore 2.0

    Hello,
    I've noticed that whenever I import an .m2v into Encore, the bit rate reported in Encore is 2Mbps lower than that reported by other programs (e.g. AVICodec).  For example, I'm trying to make a DVD from an .m2v created to have a bit rate of 7.7Mbps in Apple's Final Cut Pro/Compressor, but imported into Encore as an asset, its bit rate is listed as 5.7 Mbps.  I need this DVD to be of the highest quality possible, so I figure that by creating an .m2v with an outside bit rate of 10Mbps, it will come into Encore with a bit rate of 8Mbps.  Is this the right way to approach this problem?
    In the past, I've run into the same issue with importing .m2v's into Encore and have opted to import .avi's instead and let Encore do its own transcoding.  (Importing .m2v's into Encore sometimes creates weird blips in the video too.)  The problem is that this time I want to create a DVD from an uncompressed HD Quicktime.  (Since I'm a PC guy, a friend with an Apple computer is doing me a favor by converting the uncompressed HD Quicktime into .m2v for me.)
    Any suggestions or advice will be greatly appreciated.  Thanks.
    -R

    >Even if things have been changed on my system why should Encore do all the transcoding, write the files to disk and then hang on this issue? Even after a fresh re-install with all registries cleared etc?
    An uninstall/Reinstall will almost certainly *not* clear out the registry, or even all the common files installed. Otherwise, you would be able to install a trial version, then uninstall it, and re-install again for another 30 days. This obviously doesn't work - so uninstalling is not removing all the relevant files.
    Another common problem is that badly written 3rd party apps often reset the merit order of DirectShow related codecs, and this can mean that even when you think you're using one codec, the system (not Encore, but the OS) will use another one altogether. This can mean that what you
    i think
    is one type of AVI file is actually a different one, with perhaps an older version of a codec used to create the AVI being used because a codec pack installed/overwrote the good one.
    I have had this happen to me - and it is a pig of a problem.
    I could be completely wrong though.

  • [Bug] iOS 5.1 missing covers after "convert higher bit rate songs to" with iTunes 10.6

    All my music has covers in iTunes Library. But after i updated to iOS 5.1 they are missing on my devices.
    It happens every time i check "convert higher bit rate songs to 192/256 kbps" on iTunes 10.6 (40) on my Mac.
    On the screenshot (iPad 2010 running iOS 5.1) Bon Iver's album copied by default settings, and Coldplay's album converted to 192 kbps.
    BTW on my old iPhone 3G (iOS 4.2.1) all covers are OK even when convert feature is ON.

    I have solved it by unchecking (momentaneously till apple fix it) the "Convert higher bit rate songs" option.
    I know that it need more space but i don't have too much music synced so.. it isn't a problem for me..
    I have this problem because i'm using the "manually manage music and videos", i'm not using the auto sync option because iTunes always try to copy my new apps to my mac even having that option unchecked...
    Now we have iCloud... i don't know why apple still have not deleted this feature!
    Anyway... i have solved it momentaneously.
    Apple.... come on!

  • Won't import at 320 bit rate?

    HI
    I'm running the latest ITunes software on windows xp home and want to import audio cd's at 320 bit rate. I select this option in the custom settings and it appears to stick, but when I check the song's after importing has finished they have imported at 128 bit rate.
    I've tried deleting the 2 itunes.pref files as stated else where but no luck..
    Can somme one pleeease help me?

    Hi Guys
    Thanks for the info, I gave it a go and changed the screen resolution and the weird thing is that I could already see the apply buttton on the original screen resolution BUT when I changed the resolution it worked!!
    I don't see the logic in how window's screen resolution effects the importing bit rate of Itunes?
    I suppose that's what you get when yoou throw apples at windows, Broken glass!
    Thanks for the help

  • Why can't I choose my download bit rate?

    I import all my CDs in AAC 256 bit rate, why can't I download music that I buy from iTunes at that bit rate?
    If I am going to pay for a song, i want it at a decent quality bit rate, guess I just have to buy the CD anyway, so much for downloading convenience.

    You can't. The store sell downloads @ 128, that is ALL they sell. The record companies provide the files to the store & most record companies are not in favor of providing CD quality downloads.
    This is exactly why I have gone back to buying CD's, the quality of the store files do not meet my needs. I will buy the occasional song from the store when I do not wish to buy the complete CD.

  • Importing Problems. Bit Rate Variations

    I've customised my CD importing bit rate to 192kbps. However, when importing songs they can be anything from 180-195kbps when stored. This started all of a sudden - I have 4000 songs at 192kbps. Any ideas?

    I just noticed in that after updating to 7.6 that if you're attempting to import discs to AAC using VBR that it shows up as a constant bit rate now. It seems to be the flip problem that constant bit rate users had with 7.5. I'm kind of annoyed by this because I'd been importing my entire library (A thru S) using the VBR settings and now everything seems to be coming in flat when I start ripping. Or are they VBR and just showing as constant? Either way, I hope it gets fixed. I hate having 3/4 of my files showing VBR and the rest CBR.
