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.

>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.

  • How Can I Make Encore Create a Bluray Image that uses a Bit Rate that Really Fills The Disc?

    I have searched and browsed but have not seen this specific issue.
    I realize that if you leave the bit rate alone, Encore will use the best bitrate. In my experience, it doesnt. I have also found that the Disc Info on the Build tab is never correct. The final transcoded size of the ISO is always very different from what is shown.
    With the current disc I am making, I am encoding 4 HD m2t video files that total 20 GB on disk. The total running time is about 1hr 50m. Leaving everything set to defaults, the final size of the ISO file is 12 GB. I would like the final size to be around 20GB. I would expect that Encore would do this automatically. Changing bitrate in the project settings and re-transcoding does not change the final size. If I manually set the encoding, the size does change but since the Disc Info is unusable, it is excruciating trial and error. You have to pick settings that you think will work, wait hours for it to transcode, then it is way to big or way to small. I cant figure out how to get it to my target size.
    Also, when I transcode the files, Encore never lists the bit rates of the transcoded files. The field is always blank.
    It may also be note worthy that I have to first transcode the files, then build the disc. If I dont do that, the transcoding will hang. Even when I do separate the steps, sometimes when I build the disc from the transcoded files, the build of the disc still hangs.
    I am running a 3 GHz Quad CPU with 4 GB of Ram in 32 bit XP Pro. I have 5 physical drives of 500 GB each. I also use separate physical drives for the source files vs the target ISO. Disk space is not an issue.
    Also, is there any timeframe for when Adobe is going to release a new update? I have also run into other problems on this forum like the wonderful error 6 and the hanging transcoding, although my solutions to both problems were different than what was posted. It is all hit or miss.
    Does anyone know if Adobe going to add a feature like on other disc authoring programs where you click a Fit to disc button and it then calculates the best bit rate for the specified disc size? That would make me very happy.
    I would appreciate any help here.

    Encore does have a fit-to-disc feature, called "automatic transcoding", which chooses the bit rate based upon how much media there is to encode, how much room is currently on the disc, and applying format-legal restrictions (minimum and maximum bit rates allowable by the format).
    So for instance, 30 minutes of video will never fill a disc because the required bit rate to do so would be higher than allowable by the format.

  • Fixed bit-rate varies from song to song

    after importing a cd (bit-rate set to 256 kpbs (stereo), 48 000 kHz, NOT checked the Use Variable Bit Rate Encoding box) i see thet the songs have been imported with bit-rates that change from song to song (like first song 258 kbps, second - 257 kbps, third - 251, fourth - 237 and so on).
    could anyone please explain why so?
    thanks in advance!

    Thanks for the thread, though it's an iTunes for Windows thread. Any info. for Mac?
    Meg is correct, the issue is not specific to Windows, it is specific to QuickTime 7.3, on both platforms.
    After reading through the thread, and others that it points to, I get the impression that the changes are supposed to be improvements. And probably are for the majority of people.
    On the other hand, there are a number of specific cases where the new behavior is actually a problem. If you're using Doug Adams's excellent Join Together script (http://dougscripts.com/itunes/scripts/ss.php?sp=jointogether), with varying bitrates between tracks, you can no longer use the Pass-Through option, which means that the script can take much, much longer to complete.
    And I've gotten reports from some people that at low bit rates, e.g., 64kbps and lower, imports using QuickTime 7.3 have some kind of static noise, that is not there when the same disc is imported / transcoded with QuickTime 7.2. So I think there are some software defects to work out, too.

  • 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.

  • 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.

  • Variable bit rate audio assets cannot be imported

    Extracted some ac3 files from personal content DVDs I authored and burned myself (using DVDSP) to make a compilation. When I try to import these 5.1 ac3 assets, DVDSP is refusing stating: "Variable bit rate audio assets cannot be imported." These ac3 files play fine in QuickTime and other programs that handle ac3 files.
    Can anyone help?

    Hi:
    Please give us some info about the original movie/audio formats and what encoding presets you used in Compressor.

  • 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

  • TS1717 when trying to import cd the following message appears "the current encoder settings for bit rate and sample rate are not valid for this file"?

    Trying to import cd when this message appears "the current encoder settings for bit rate and sample rate are not valid for this file".  Any suggestions?

    Thanks so very much.  I chose MP3 and Download and it is working beautifully.  Have a wonderful day and it is so nice of you to get right back to me.  I'm trying to cut a DVD for my grandson's grad party and I got most of the photos and didn't have any music since I lost everything in a clean install.  Could hug you!

  • 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.

  • Random import bit rates?????????

    My import settings are set to: 192kbps 48Khz AAC with NO variable bit rate. For some random reason itunes stated importing my music at random bit rates usually 3 to 7 kbps below my set rate. I decided to "factory refresh" my computer as it was time hoping it would fix the issue but nothing had seemed to fix it unless I install itunes 6.X and even then its a pain. 192 MP3 works great but the AAC encoder is having issues. Any suggestions? itunes says: "encoded with itunes v7.5.0.20, quicktime 7.3.1." is there a new codec or anything.

    As I believe first came to light in this thread - courtesy of a heads-up from Flynn and verification and a workaround (if it really bothers you) by b noir - there was a so-far undocumented change in the new version of QuickTime (QuickTime actually being responsible for encoding song files in iTunes) which came bundled with iTunes 7.5.
    QuickTime no longer supports Constant Bit Rate Encoding. In its place is Average Bit Rate Encoding.
    Although this change is not reflected in the iTunes User Interface, it accounts for the new state of affairs that you noted.

  • 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

  • Irregular Bit Rates for Converted/Imported AAC files (iTunes 7.5)?

    I have noticed that my recent additions to my iTunes library have irregular bit rates inconsistent with the usual 128 kbps. They range from 121-131 kbps and appear to be randomly generated. This has happened with MP3s and WMAs that I have converted into AACs and CD tracks that I have imported as AACs. My first additions with these problems were on the 19th of November. Before this time I updated my library to iTunes 7.5. None of my previous 2000+ music files (all AAC) which I have been adding successfully for the last 3 years have had this problem and they are almost all (except for a couple at 64 kbps) at 128 kbps. My suspicion is that the new iTunes 7.5 may be the cause of this irregularity.
    Has anyone else had this problem?
    Any help with this would be greatly appreciated.

    Sorry, I found a past thread related to this issue. No Need to reply

  • 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.
