Which codec?

Hi,
I have an .avi file that has no audio in QT 7.1.5.
No audio in DivX Player, DOES have audio in VLC.
These are the audio specs:
DivX 6.0, 564 x 308,
Unknown ATSC A/52 and AC-3 Decoder, Stereo, 44.100 kHz
I have these codecs in /Library/QuickTime:
Sep 20 08:39 AC3MovieImport.component
Dec 9 2005 AppleIntermediateCodec.component
Mar 9 2006 DivX 6 Decoder.component
Sep 21 11:41 DivX Decoder.component
Sep 21 11:41 DivX Encoder.component
Which codec do I need?
TIA,
Charles

if you notice, I have both the A52 and DivX codecs in /Library/QuickTime.
You made no indication as to where that A52 codec came from. The one I pointed to is a current project, so if that's not the one you have, you might give it a try.
If that is what you have, or the one I suggested won't work, then you're probably out of luck. You'll have to go back to the person who created the file and ask him/her to create a copy that doesn't use AC3.

  • How can I determine which codec to use?

    I'm using PE7 on a PC. I have HD video shot with a Canon. Each video - there are six of them - is less than five minutes. After I finished editing, I uploaded them to youtube and emailed a link to my client, but my client complained that they were out of focus. I explained that it was the compression that youtube uses, and that I'd render them to disk for him to look at.
    Trouble is, I can't figure out which codec to use. All I know is that I want clear, sharp video, suitable for posting on the net. These are scientific videos, showing some chemical processes involving gasoline with ethanol and water.
    Can someone point me in the right direction?
    TIA

    I guess I need to explain better. The HD videos I'm editing will not end up on youtube, but will be posted on a government agency's website. I originally posted them on youtube just so the client could take a look without me having to attempt to email large video files or burn to disk, since the client is in a different location from me.
    The area of video editing and production that I'm the least knowledgeable - and therefore the most insecure - is when I attempt to render and save a video. Every video project I go through the same frustration of having a project that I'm happy with, but having a final product that either 1) does not look at all sharp or 2) results in a file size which is too large. In this case, since the final video files will be posted online, they need to be small enough for viewing over the net while maintaining enough sharpeness and quality that the video does not look out of focus.
    If you take a look at this video, for example: http://www.youtube.com/watch?v=t_X0IKPJrng you can see why my client thought it was out of focus. However, I know that the original footage is very sharp.This link is only temporary, as I've already been told that the agency I work for will not allow them to be posted on youtube.
    So, my question is, when I'm rendering and saving a video project from PE7, how do I know what settings to use for the highest quality, yet smallest file size? The manual does not go into much detail about the pros and cons of various codecs, nor does it say much about what settings do what. It's like Adobe expects me to already know this information.
    Is the problem with the video above simply that youtube compresses the videos I upload? Is Vimeo a better site to upload videos and maintain sharpness? In PE7, is there a way to set it up to upload to Vimeo, or should I render and save as an MP2 or MP4 file and then manually upload?
    Surely there's a site which goes into much greater details about the various settings I can use in PE, and how those settings affect the final viewing product.
    Thanks a lot for your help. I realize my questions show an extreme lack of experience, but that's why I'm here, right?

  • Bluetooth: A2DP. Which codec is used in iOS4.3

    Hi,
    does anybody know, which codec is supported for BT A2DP streaming?
    SBC (default)
    AAC?
    MP3?
    apt-X?
    Br
    Timo

    Then again, this is from the JBL press release :
    The JBL OnBeat Xtreme iPad dock supports advanced A2DP and AVRCP Bluetooth profiles for interference-free operation, and uses the higher-quality AAC codec – supported by Apple’s iOS devices, gaming consoles from Sony and Nintendo as well as Android smartphones – for superior audio streaming.

  • Send to Premiere Pro - Which codec?

    I tested ingesting some sample footage, copying the original footage to a folder, then also two transcodes, ProRes 422 and Prores Proxy each to their own folders. 
    I then sent the project to Premiere Pro.
    Is there some rule about which codec Premiere Pro will link to?  Is it the order that the transcodes are queued, or the original media or what?
    The Premiere Pro project I ended up with had mixed codec types.  Some were native, some were ProRes 422 andsome were Proxy, which is not quite what I'd hoped.
    If I know what the rules are I guess I can follow them, but I can't find where these are written down. 
    Thanks.

    I did the test again with multiples cards and different transcode order (copy / mxf / prores, mxf / copy / prores, prores / mxf / copy) and I did end up each time with my first choice into the prelude project.
    I'm using Prelude 1.0.2 and Adobe Media Encoder 6.0.2 on Mac OS 10.8.1
    I don't know if this has anything to do with it but I allways launch AME before starting ingest (not letting prelude launch it by itself).

  • Which codec do you use?

    So I figured I asked the community and get a feel of which codec(for Quicktime) you use when rendering from Shake and why?
    I'm trying to find a nice balance between quality and size for importing Quicktime movie into iMovie. It seems I can't get the right quality in iMovie but maybe it's because iMovie is messing with my original movie.
    Thx.

    Sorry I wasn't as specific. I am using sequence TIFF images which are 720x480 or less depending as input and want to ultimately build something with iDVD. I have been using the 8-bit uncompressed codec to keep as much quality as possible but I was just curious what other people use when doing their work with Shake.
    As for using iMovie, I could do everything in Shake including the audio sequences but it's so much easier to line up audio clips in iMovie. I may resort to this as iMovie keeps murdering my resolution. I just didn't feel like dropping $170 on FCE or even more on FCS which is why I was using iMovie to build my movie. Based on a lot of investigation earlier this year, I could do all the work I wanted in Shake without needing FCE and just output to iMovie 09. I'm just a hobbyist.
    Thx.

  • Too many choices, Which codec do I choose?

    I am not new to FCP or DVD SP but I am new to the HD world. I have edited my first HD movie using FCP HD (1080i60 format) and the movie is 1 hour and 25 minutes long. It is an instructional video. I used Quicktime compression and selected H.264 because I thought it would result in high quality and a small file size. Two and a half days later the compression completed and the file is 13.4 GB. All I really want to do is to get the best quality video into DVD SP4 so that I can take the best advantage of my HD video and keep the movie to only one DVD if possible. I have to admit that I am lost when trying to figure out which codec to select. Any help would be appreciated. Thanks

    First of all, transcoding from HDV to h.264 results in compression.
    Not only that, but h.264 is a codec that cannot be used to create a SD DVD in DVD SP. It requires Mpeg2/m2v files.
    Simply export your HDV movie to your scratch disc with current settings, no recompression, video and audio self contained.
    Drop that into Compressor and elect the 90 minute best 16:9 setting, and the Dolby 2 audio setting.
    Take the m2v and ac3 files, and import them into DVD SP as assets.
    Make certain that the track is set to 16:9.
    Might want consider Sitter's book on DVD SP.

  • Find which codec is used?

    How can I tell which codec is being used for sound in an avi file.  I have problems playing some avi's in VLC.  The sound is crackly.  Other files are fine so I figure there is some encoding difference I wanted to track down before I reported a bug.  Totem plays the files fine.

    btw...
    theres a command in linux that can be used to get info from any file, its called file
    file /media/Files/Download/movie.avi
    /media/Files/Download/movie.avi: RIFF (little-endian) data, AVI, 640 x 272, 25.00 fps, video: XviD, audio: MPEG-1 Layer 3 (stereo, 48000 Hz)
    as for your other problem, could it be a problem in the video instead of vlc?

  • Which codec does itunes encode its films and videos in?

    Thanks for your knowledgeable answer,
    Eaglepeak
    Eaglepeak, by no means am I an expert but I have navigated through this forum and found so many frustrated people doing "The Codec Dance" for avi file codec. I grew weary of this "dance" put the search on and found a little application that will convert your avi to DivX, worked for me and others. Give it a try, free download at http://www.feringa.net/downloads/avi2DivX.jar

  • Don't know which codec i need exactly. Anyone?

    I was using Final Cut Pro 5.1.4 with mac pro
    exported a project 720p25 with "export>using Quicktime conversions",
    and now i am getting a white screen with sound fine.
    The info viewed in quicktime movie info:
    Format :
    16-bit Integer (little endian), Stereo (LR), 48000kHz
    HDV 720p25, 1280 x 720(1248x702), Millions
    so i was wondering which codec i need exactly. Anyone?
    Many Thanks

    Actually i am using the fcp with mac pro at my school's apple training centre
    and they told me if i export it WIth using quicktime conversions
    i can watch it with quicktime, and just quicktime, nothing more
    i believe that's what he meant.
    and the mac pro did work fine playing the mov with quicktime only, not also opening the fcp.
    I mean, it happens a lot, right?
    some videos just don't work on your mac but his is fine,
    that's the computers' problem not the video, at least i think..
    and i've been looking for other topics in the forum,
    and most of them said look for codecs or even third party codecs,
    turned out most of them mark the question solved.
    that's why i thought the quicktime message was right,
    some codecs are missing. it's just that i ended up failing finding the codec i need

  • Easy Question: Which Codec?

    I'm doing 24p 16x9. Which codec should I render my quicktime out to get the best picture?
    PowerMac G5   Mac OS X (10.4.4)  

    Simple, export to quicktime movie option (not conversion) and make sure that the recompress option is unchecked and the "make movies self contained" in checked. I've asked the same question and it seems that that one option is as good as you can get. Anything that you try and export with higher settings is trying to up-convert and recompressing frames.

  • CP 4 swf to avi... which codec is best

    I have been testing the swf to avi feature of CP 4. I'm
    curious if anyone out there has any experience with the codecs that

    with CP 4. Any help or suggestions would be greatly
    appreciated.

    So far I've not managed to come up with a happy medium for
    this. I tested
    several CODECs last week and found the process slow and
    unreliable with the
    file I was working on. In part, the answer depends upon which
    CODECs you
    have installed.
    I think I ended up using Intel IYUV for my final publish
    test, and it was
    'ok'.
    One of the Adobe engineer suggested Cinepac Codec by Radius.
    This, in
    computer terms, is a prehistoric CODEC. It is not very
    advanced (it's not
    mpg4, DivX or whatever) but that's probably a good thing.
    The best answer really is just for you to experiment,
    unfortunately, until
    some patient soul turns up with more detailed advice :-)

  • How to tell which codec

    I have an .avi movie that Premiere imports only as audio and not video. This video plays also bad on Windows Media Player or Winamp (same problem, only audio), but plays well on e.g. All Player. So it is probably a problem with codec, which only All Player read..
    So I have a question: how to recognize which codec is used? I thought avi is just avi, but found out on these forum that more people had this problem and the solution is always: bad codec. Is there a method/program that would allow me to check which codec was used for this particular video ? Unfortunately All Player does not show information about codec, only size and fps of the movie. So what I think about is a program that would open the clip and recognize which codec was used and display this information. Is there such a program? All I want to know (for now) is the name of the codec. Knowing the codec, it will perhaps be possible to re-code in some other program to a format suitable for Premiere..

    Does it open with Quicktime? If so, in the Quicktime window, under the window menu or control + j, choose "show movie properties".
    I've had this same problem (audio, no video) with files brought to my PC from a Mac that are encoded using the Apple Intermediate Codec.

  • Which codec after importing AVCHD files?

    I have AVCHD files, saved to card in the camera. 
    The files have .MTS extension, so I'm using ClipWrap to convert them to files that Final Cut Pro 7 can use. 
    I need to do basic editing with these video files and export them back out so another editor (on another computer) can do more elaborate editing with them.
    To maintain the 1920 x 1080 HD quality of the original files, which codec should I use in ClipWrap?  I tried the default one ("Rewrap - Don't Alter Video Samples") but that file doesn't work well in FCP (it imports, but scrubbing and editing with it is nearly impossible).  Other options listed include Apple Intermediate Codec, Apple Pro Res, Apple Pro Res HQ, Apple Pro Res LT, Apple Pro Res Proxy, and HDV.
    And then -- exporting the clips back out for the other editor:  which settings?

    Prores 422 should work fine.  If you have the card or have copied the card contents with folder structure intact, you can probably just use log and transfer within fcp instead of clipwrap.  What camera was the material shot on?
    If the other editor is using fcp, give him the prores files,.   If not, ask him what editing system he will be using and what kind of files he wants.

  • Which codec for 1024 x 768 clips (mainly Photographs in two or more layers)

    Hi!
    I want to create a Rearprojection as a background for a theatre play. The footage is mainly high resolution photographs which I edited in photoshop. I want to use two or more layers with transparant areas (eg. a wall with windows and a moving landscape behind the wall. Through the windows you can see the landscape).
    The projector works with a resolution of 1024 x 768 and therefore the videoclips should have the same resolution.
    As the clips will be looped and are quite short (from 1 to max. 5 minutes) the size of the videofiles doesn´t have to be very small.
    Which codec should I use to achieve good quality?

    I will use either Final Cut Pro directly or a Video Player named Qlab.
    The footage will be put on a MacBook Pro Core 2 Duo which is connected with the video projector via a 5x BNC (RGBHV)-cable.
