![]() Since the QT 7 Player only plays program stream files, use of the MOV file container was previously common. (I.e., H.262/MPEG-2 video multiplexed with MPEG-1 Layer 2 audio.) Such files can be wrapped in either transport stream containers like TS, M2T and M2TS or program stream file containers like MOV, MPG or MPEG. Does that help? Also, this video camera is several years old.īased on the information provided, I suspect the files are HDV encodes. mov file the only information I see is the dimension such as 720x480 or 1280x 720 and Codecs: H.264. I do not know what form of compression is used but the original manual says to open with Quicktime 7 to view the video on a pc computer. I record these files on a HD DV camera that saves the movies in a. Thus, the first question usually asked is "What form of audio compression is used in the MOV file and/or at what sampling/data rate combination?" Since MOV file containers may store audio data which may or may not be "native" playback compatible with the AVFoundation or may employ audio settings that the AVFoundation may "dislike," it is possible that either is the source of your current issue. Since Mavericks, QT X playback is directly supported by a "closed" codec AVFoundation structure embed while QT 7 is supported separately by the "classic" QT 7 structure embed which employs an "open" codec access as configured by the user. ![]() I was wondering if the recent upgrade Apple put out maybe is causing this issue?Īudio playback issue may have been triggered by the upgrade to Sierra depending on the Mac OS X version you upgraded from. I thought I had played movies before since upgrading my computer 6 months ago to Sierra but now I am not for sure. I am using OS 10.12.5 on an iMac intel i3 3.0 ghz mid 2010. I know the movies have sound because they work fine if I use Quicktime player 7. There is not even a sound icon in the playback control panel. I am using Quicktime player 10.4 version and when I try to play a movie file I get no sound. (I.e., my system is on virtually 24/7 and is normally engaged in turning out "batch" conversions whenever I am not actively working on other projects since I am constantly updating and refining my iTunes managed video library.) ![]() This can be of great help if you have a very large number of files to be converted. That is, you can queue up a list of files along with their individual conversion settings and allow them to run while you are asleep, are off working and/or performing other tasks. Unlike the current QT 7/X GUIs, most dedicated conversion utilities, including HandBrake and the iSkysoft iMedia Converter Deluxe app, allow "batch" processing. ![]() However, if you plan to archive all of your camcorder files and edit them extensively in a video editor, then the ProRes422/LPCM MOV files would probably better suit your long-term requirements.įor the moment I will continue to use quicktime player 7 but I will need to purchase iSkysoft and convert all my files at some point. If all you require is the ability to play and trim your files for distribution, then HandBrake may be all you need here. I.e., H.264/AAC encoded media in MOV, M4P or M4V containers is normally used for distribution of your final content while ProRes422/LPCM MOV files have become the virtual default "poor man's intermediate codec" format (replacing AIC/LPCM MOV) for most users and is primarily used to archive and edit media content on all Mac OS X platforms since Mavericks, as well as, the latest MacOS Sierra. HandBrake would work as well and is free but limits your output to MPEG-4 or H.264 video with AAC audio if you want the output to be totally compatible with all QT X/QT 7 based apps. Almost any similar app will work as well so you should be able to easily find one that suits your individual needs, design fancy and pocketbook. I mentioned it by name only because I used it to convert the sample HDV content to ProRes422 on my system while answering your post. ISkysoft is representative of a class of third-party conversion apps available that are based on the FFmpeg open source codec project which can transcode most common modern and legacy compression formats in use today. I downloaded iSkysoft and was able to convert a file (1/3 only without purchase) to a file that the new Quicktime 10.4 would play.
