Audio format for movies

Apple claims that movies downloaded from the itunes store support surround sound but is it 5.1 channel sound?

HD movies are for the tv only.
They are 720p and audio can vary between stereo and 5.1 depending on how the studio encodes the title.

  • Video and audio formats for iPad

    Hey, guys.. I've tried searching this up in the forum but didn't have any luck with that..
    I can't seem to upload my movies and songs into iPad... I tried converting my movie into .mov and .mp4. They can both be imported into my iTunes library but when I drag it to the iPad tab it says it cannot be copied because it cannot be played on the iPad. And some of my albums just can't be imported.
    May I know the preferred format for my movies and my songs? And what could be the problem with my importing..
    Thanks heaps.

    Here are the spec for video and audio for the iPad:
    H.264 video up to 720p, 30 frames per second, Main Profile level 3.1 with AAC-LC audio up to 160 Kbps per channel, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats; MPEG-4 video, up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, Simple Profile with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats; Motion JPEG (M-JPEG) up to 35 Mbps, 1280 by 720 pixels, 30 frames per second, audio in ulaw, PCM stereo audio in .avi file format

  • Format for movies to use in iMovie 08?

    What format do movies have to be to use in iMovie 08?

    What format do movies have to be to use in iMovie 08?
    AppleMan and Patrick have basically covered the import/capture formats. However, if you are importing files at the Finder level, then DV (DV audio with DV video), DV25, DVCPRO25, DVCPRO50, AIC, Motion-JPEG, Photo-JPEG, MPEG-4, and H.264 are probably the ones most commonly used. For audio -- DV, Linear PCM (Big Endian & Little Endian) , and AAC are probably the ones most used. NOTE: Avoid Apple Animation and Apple Video files. They will import and edit but will not export properly.

  • Audio formats for broadcast from DVD

    Hi--
    I have a 2 minute project that will be aired on TV from a DVD. I am trying to choose the best format in Compressor to export for DVD. Seeing as it's such a short piece, I have plenty of room. My project is cut on FCP 5.1.2 and is a 720x480 NTSC - CCIR/DV project with footage mostly from DVD and audio from a stereo CD and other stereo and mono sources.
    On the video side, I have noticed no quality difference between exporting an uncompressed 10-bit file and an mpeg-2 6.2Mbps 2-pass 4:3 file. They look the same to me on DVD on my TV.
    On the audio side, I am not sure whether to use Dolby or AIFF, then within those options whether to use AIFF 96/24 (that's PCM, right?) or 48/24 or Dolby (Auto) or 2.0. I just don't know enough about audio.
    I use Toast Titanium to burn my DVDs, and it too has a variety of custom output options. It allows me to have an average and maximum bit rate up to 9.0 Mbps and allows me either PCM 96/24 or Dolby Digital up to 448 kbps.
    My research has only granted me piecemeal info, as most people are concerned with file size and have to make choices with that in mind. I know people are reluctant to give strict guidelines on this site and that some of this is subjective, but can someone tell me what would technically give me the best (meaning most) video resolution and audio clarity?
    Thanks,
    Mike

    Is PCM the same as 96 khz/24 bit AIFF, or are there ranges of PCM?
    If my original sequence audio is set at 48 khz/16 bit, is there any advantage to PCM or is it just an exercise in futility?
    PCM and AIFF are basically the same thing: uncompressed audio. Look this links just as information:
    http://en.wikipedia.org/wiki/AIFF
    http://en.wikipedia.org/wiki/PCM#EncodingforTransmission
    You can have uncompressed audio 48kHz/16bit and 96kHz/24 bit. DVD standard accept PCM (AIFF) 48kHz/16bit. Then your original audio format from your sequence is fine to use for DVD authoring.
    What is the difference difference between MPEG-2 with a high Mbps and Uncompressed 10-bit? What should I really be using for a DVD?
    If your FCP project/timeline is DV NTDC, no use to export as Uncompressed 10-bit. You cannot get a better quality than your footage, and this is encoded as DV.
    MPEG-2 is the oded video used in SD DVDs. No matter what video source you use to build your disc in Toast, finally you'll disc will have a MPEG2 video inside.
    Then from FCP sequence use Export > Quicktime Movie > Selfcontained leaving currect settings. You'll get an independent file with same quality that your timeline that you can use for your build in Toast or encoding in Compressor.
    Hope it helps!

  • Audio formats on .mov file

    Hi all,
    I need to generate a video recorded file from an embedded device (network video recorder) that can be imported from Final Cut Pro. The easiest formats for me to generate are .mov with H264 video format and ulaw audio format, but I have been told that this is not supported by Final Cut. Can anybody point me out to a list of supported formats by Final Cut in both .avi and .mov?. Ideally it should be H264 for video and ulaw or alaw stereo audio format.
    Thanks

    Hi,
    you can read Final Cut Pro 7 specs, listed here:
    http://www.apple.com/finalcutstudio/specs/#finalcutpro
    AIFF is a format that you can edit directly without the needs to render.
    Also check FCP documentation. From its pages you can find this:
    Recommended Audio File Formats
    For best performance, use one of the following uncompressed audio file formats when
    editing in Final Cut Pro:
    • AIFF or AIFC containing uncompressed audio
    • WAVE or Broadcast Wave Format (BWF) containing uncompressed audio
    • Sound Designer II
    • Single-track or multitrack QuickTime movies containing uncompressed audio
    Natively, Final Cut Pro captures to QuickTime movie files with one or more audio tracks.
    Audio Formats to Avoid
    The following formats and audio data formats should be avoided when editing in
    Final Cut Pro because they require real-time processing for playback:
    • Any file containing compressed formats such as MP3, AAC, and Apple Lossless Codec
    • QuickTime movies containing compressed audio, such as MPEG-4 and H.264 files
    • Multiplexed video and audio streams such as MPEG-2 program streams and DV Stream
    files (This is one of the formats iMovie can create during capture.)

  • Best audio format for recording speech?

    Hello everybody,
    I was wondering which audio format (encoding, sample rate, sample size) is considered best for recording speech in regard of memory usage and perceptible/acceptable quality loss.
    What do you suggest, what are your experiences, what reasons can you state?
    Thanks!

    I finally found something:
    [sample rate for speech|http://wiki.audacityteam.org/index.php?title=Sample_Rates#32_kHz_.2F_14.5_kHz]
    [bit depth|http://wiki.audacityteam.org/wiki/Bit_Depth#16_Bit]
    I know audacity is not an application based on the java sound api but these wiki articles provide good common information on signal processing.
    According to the article I believe 32kHz ist the optimal sample rate for recording speech. But I still don't feel satisfied by the information given about the bit depth. I think 8 bit is too low but 16 bit (CD quality) might be too sumptuous. Unfortunately the quality I can record with is limited my recording and output hardware so it might become hard for me to top that out. Maybe someone can help.
    Is it true, that the encoding can be customized with codecs by extending the audio service provider? How would something like that work?

  • Audio Commentary  aka  alternate audio file for movie.. How?

    Hi folks,
    I love this discussion group btw... awesome...
    So, I've got my feature film done, we did a 1 week run at the theatre now, we are almost ready for our DVD release but want to do one of those really cool Director Actor commentary / alternate audio files for the movie. Is this done in FCE or iDVD? and any tips?
    Best Regards,
    Mark

    ... I think there is a workaround with FCE + iDVD.
    You could duplicate the original sequence in FCE, then add your alternate audio to the timeline of the new sequence. (Record your commentary and add as a 2d audio track (say, a3/a4)). Raise & drop the audio levels appropriately across the length of your regular and alternate audio tracks. Export the resulting video to QT Movie and import it into iDVD along with your original Movie.
    You will now have 2 versions of your Movie & can put them both in a single iDVD project (of course, subject to the limitations of the total length you can put on a DVD (~2 hours for a single layer DVD, ~4 hours on a dual-layer DVD.) Or just put them on separate DVDs if your Movie is too long to fit both on a single disc.

  • HT5176 Audio format for dictation?

    What is the audio format used to capture dictation on the new iPad that is sent to Apple servers for transcription?

    Hi Meg,
    I don't have an iPad, but I am writing about the feature. If I had one, I wouldn't need to post this item. I would just sniff the network and review the transmission sent to Apple.
    I am writing about the feature in a story and I am assuming the audio content has to be captured in some file format to be delivered over the web.

  • Dual monitor use audio output for movie and other for MBP

    is it possible im watching a movie on one and wated to answer factime call or watch youtube on my mbp and just screamed out my tv speakers.....i want fual monitoring but separate audio any help?

    Other alternatives include
    I know on mackbooks I've seen firewire used as an input for a Weiss Dac if you're into two channel audio.  Do any reiceivers take firewire as an input for hometheater?  Has anyone tested Firewire outputs on their W series?  I'm told that firewire is sometimes preferable to USB, I'm not sure why this would be, can USB support passthrough of DTS encoded signals?
    In the case that firewire works and you Do not have a firewire source, maybe something like this would be of value  It converts firewire to digital coaxial s/pdif and allows passthrough of DTS and AC3.
    http://www.m-audio.com/images/global/manuals/FireWire-Audiophile_Manual.pdf
    As I'm into audio the critical thing here (and what you're paying for when you purchase blue-ray, is maintaining the digital information from the disk in an unconverted form.  You want a direct bit pass through, and you want as little jitter introduced to the signal as possible.  You most certainly don't want the sound card getting in the way, Digtital to Analog converting and then reverse packaging it up and putting it out over the soundcard digital out.  My problem is I'm not familiar enough with computer audio to know how exactly the sounds is transmitted from your blue ray drive to the digital interface you've chosen.
    Anyone know why USB digital out would not be a prefered method?

  • Formats for movie clip used in PSE 4 slide show

    Still finding it difficult to find documentation of what formats are supported for using digital camera movie clips in PSE 4 slide show.
    The movie file from my Canon camera is 640 x 480, 30 fps Motion JPEG and has a .AVI extension. I am able to use it "as is" in a PSE 4 slide show. However, sometimes I need to trim the movie clip in Windows Movie Maker 2 in order to keep only the best part.
    My question is what parameters can I specify to save my movie clip in Movie Maker 2 so that I can use it as a movie clip in a Photoshop Elements 4 slide show that will be saved as a WMV file?

    Karin Sue,
    >Also, are the projects saved in a folder somewhere, or only as part of the Catalog?"
    The definition of the "project", which is the "Creation" in Organizer terms is saved only in the Catalog.
    >If you publish your creation as a pdf or wmv they are saved in the folder you designate. Once published, I don't believe there is any way to edit. If you save the creation, you can go back and edit and republish if you like.
    Yes, the WMV or PDF file is saved in the folder that you designate. You are correct that if you save the Creation, you can go back and re-edit. When you Save the Creation gets a thumbnail within the Organizer photo well and you can click on the thumbnail to go back in to the Creation process make modifications and save a new WMV or PDF file.
    Note: that the Save window documents that the PDF choice does not support some options such as Pan and zoom, videos, and certain transitiions.

  • Correct Format For Movie File

    Hello,
    I am in the process of transferring old family film footage to digital files. The company I'm taking these reels to is recommending that I put them on an external hard drive in .mov format. They say that this will allow me to edit with iMovie. Your thoughts?
    Also, at the present time when I upload my point and shoot Nikon camera and also when I upload my iPhone and iPad, the movie clips are loaded into iPhoto also along with the photos. Will I have the option to do this with these new files?
    Regards,
    Tom

    You would need to consult the documentaion for the device you're using. You should be able to find it on the manufacturer's website.

  • What's the best video/audio format for PPCS4?

    Question looks like a simple and stupid one, but I've noticed many differences using various kind of file extensions.
    For example when you have to put an effect.
    Mercalli is very performing if the effect is applied to an .avi file instead of a native .mpeg file taken from my Sony HDR-SR videocam.
    So the question is:
    If I have to change the video file format, what is the best one (or one of the best) I can use?
    Avi, we know, is an uncompressed (and eavy) one, but, if you have 700/800 file to edit, maybe PP could go slowly. Am I wrong?
    Of course I have tried using the same video strip differently converted.
    Wait helps.
    Many thanks,
    Ciao

    Re-thanks Harm,
    I know about .ac3 audio problems, I've posted a discussion time ago concerning this trouble.
    But now I'm mainly looking for a video format.
    Example:
    clips in native video compression are 'round 25Mb each
    converted in .avi file can reach 630 Mb
    Honestly I'll fill my entire pc with a format like this.
    What I'm asking is a suggested kind of file that can easily work with PP and if you know a sw that do it.
    I have Tmpge but I do not know  how to set it for the best results (unless I just set AVI output with the problem mentioned above).
    I've read on the forum that DV AVI could be a good chance but which good sw can give me this files?
    Ciao

  • Format for Movies

    I was wondering what format I needed to have the movie in for it to work on a DVD. I tried .AVI and went through iDVD and it played the intro part but not hte movie itself. I was wondering if it had to be in a certain format.

    DVD uses MPEG-2 Compression.

    I am working with iDVD, I have truncated some audio using Audacity I have reformatted the truncated audio to AAC iDVD does not accept it. I have reformatted the truncated audio to AiFF iDVD does not accept it. Even though iDVD help says that these two formats are acceptable. How can I make this work?

    *Not knowing the origin to Your problem - General approach when in trouble is as follows.*
    • Delete iDVD pref file - *or rather start a new user/account* - log into this and re-try
    iDVD pref file resides.
    Mac Hard Disk (start-up HD)/Users/"Your account"/Library/Preferences
    and is named. com.apple.iDVD.plist
    While iDVD is NOT RUNNING - move this file out to desk-top.
    Now restart iDVD.
    • Free space on internal (start-up) hard disk if it is less than 10Gb should rather have 25Gb
    • Hard disk is untidy. Repair Permissions, Repair Hard disk (Apple Disc Util tool)
    • Program miss-match. iDVD 5.0.2, Mac OS X.4.11 AND QuickTime 7.5.5 - is OK - DON’T work under Leopard
    • Program miss-match. iDVD 6.0.4, Mac OS X.4.11 AND QuickTime 7.5.5 - is OK (might work under Leopard)
    • Program miss-match. iDVD’08 v. 7.0.1, Mac OS X.4.11 AND QuickTime 7.5.5 - is OK (might work under Leopard)
    • iDVD (08) v7 Locate theme folder. Move out iDVD1, iDVD 2 and eventually iDVD4 folders to desktop - re-try
    • Try a Cleaning CD/DVD that cleans the laser lens on the DVD burner/player
    iDVD 6.0.4 and iDVD 7.0.1 are compatible with Mac OS X 10.5 Leopard
    Last resort. from Craig. Solved the problem!! Finally!!
    I deleted every iDVD application and folder from my boot drive,
    emptied the trash and then installed iDVD 08 using the customize option
    and I am up and running.
    If You do a re-install be sure to get rid of all iDVD old parts AND then EMPTY the Trash-basket !
    iDVD updated ?
    Apple Codec updated ?
