QuickTime :: Why Is There Audio But No Video With Quicktime Player

Feb 2, 2012

I have had this problem quite a while now:When I open an .avi file it automatically opens using QuickTime. I'd like that because it's the best player for Apple.The problem is however that I can only hear the sound, there's no image/video.I use 10.7.2. (now updating to 10.7.3), but it already did this before I had OSX Lion installed.If I search for new updates it doesn't come up with an update for QuickTime.Any other player works (although VLC's the only one I tried so far).

Info:
Mac OS X (10.5.8)

QuickTime :: Tried Playing A Video Through It But There Was No Audio?

Feb 9, 2012

I tried playing a video through Quicktime but there was no audio and the program said it needed a codec. Quicktime suggested that I download another progran (DivX player). I downloaded DivX but then the video still does not have any audio output. What will I do?

Applications :: How To Get QuickTime To Play MPEG2 Video And Audio

Nov 4, 2006

I am a new Mac user, and I bought a mac for the main purpose of video editing. However, all my files are MPEG2, and so far, I have had a very frustrating experience with trying to figure out how to play it back on Quicktime with Audio. I downloaded Pro, as well as the MPEG2 add on. It plays video fine, but can someone please tell me how to get it to play audio step by step?

Lastly, I have Final Cut and iTunes and audio won't play with the video there either. I am assuming once I have it fixed in quicktime, it will work in all other programs too?

QuickTime :: Distinguish Between MP4 And MOV Files Without Using The Extension .mov Or .mp4

May 8, 2012

I need to distinguish between MP4 and MOV files without using the extension .mov or .mp4. 

If I use FTYP major_brand = 'qt  ' as the distinguishing factor, is that sufficient? Or do I need some information from compatible_brands as well?

Can we have mov files where major_brand != 'qt  ', Ex If 'qt  ' is one of the compatible_brands but not major_brand: would we call it a valid mov file?

OS X :: Playing Mp4's In Quicktime Player X?

Apr 1, 2010

Today I updated my System to OS X 10.6.3, which included a Quicktime update

After updating I can't play certain mp4 movies anymore with my Quicktime X Player: I can hear audio but I don't see video.

What is so strange about it that until today I was able to view them without any problems.

I still can watch them with VLC player.

When I click on file info, I see these codecs: AAC, H.264, MPEG-4 SDSM, MPEG-4 ODSM

How can I solve this problem? I am using OS X 10.6

The files have been made using Handbrake.Examining the info windows in QT7 on one movie that does work and one that does not, does not tell me much. they seem pretty identical.Info copied from opened files in QT7.

Applications :: Default .mp4 Files To Open With Quicktime?

Is there a way of defaulting .mp4 files to open in Quicktime? I'm experiencing an issue in which movie files in .mp4 format are for some reason opening in another application I use for audio editing.

I can still play the movie file in Quicktime, but only if I right click it and select it from the "Open With" menu.

QuickTime :: Not Responding - Cannot Open Files (AVI / MP4)

Jun 18, 2012

No matter what type of file (.avi or .mp4) I try to open, QT immediately goes to "Not Responding"... Software is completely up to date. I don't know what else to do... It won't let me trash QT to re-install but I think that's what I need to do.

Intel Mac :: Quicktime Playback Distortion On Some Mp4 Files?

May 10, 2012

I am having a problem playing some mp4 files through Quicktime. When the video is played in Quicktime (or Pro Presenter 4), portions of the video turn into distorted white blocks that move with the video. It doesn't continue throughout the whole video, but I can't discern when or why it only affects certain portions. It does it every time at those places in the video. I downloaded VLC, and the same exact file plays perfectly fine in VLC and on other computers through various programs. I have only seen this problem on this computer. 

Is this a codec issue? How do I fix it? The files in question are mp4 files using h.264 video and AAC audio at 1920x1080 resolution. I can play other mp4s using h.264 and AAC without any problems. 

I have only had this problem with one of the companies that we periodically hire to produce videos for us. I'm guessing that it has something to do with the way he encoded the video, but I have no idea what the problem is. It's probably not his fault if it only distorts on this one computer. 

Here is what the white block distortion looks like:

iMac, Mac OS X (10.6.8), 3.2 GHz Intel Core i3, 4 GB RAM

QuickTime :: Won't Play M4V Or MP4 - Encoding Wrong?

Jun 18, 2012

Basically I've just used a reliable, tested program to rip a DVD of an old VHS recording my cousin gave me. The intention is to cut out the bit he was in and make it available to him as a digital video.The problem I'm having is that for some reason Quicktime and Final Cut are refusing to recognise either the mv4 encoded rip or the mp4 one. The program has always worked before so I doubt it's encoding it wrong and I've got reems of other m4vs and mp4s that play fine in Quicktime X and 7. It's just this one video that seems to be an issue.

I have Kigo Video Converter which is also reliable and much tested and tried converting the mp4 to an avi to see if QT or FC would handle that. All it does is freeze the program, something that has never happened before.I've honestly never had this much trouble converting home-made DVD burns into digital videos, I've done it many times before myself using numerous methods. I'm also well-versed in digital video formats and encoding and I can't find anything technically wrong with it.

Applications :: Convert SWF Files To MP3 - Free Audio Extraction Or Video / Audio Converter Exist?

May 29, 2010

I want to convert some video files (specifically swf in this case) to audio files so I can listen on my iPod. I looked everywhere and can't find some free software that does that. There are tons that have trial periods with lots of limitations (like it won't convert anything larger than a 5k size file) so I don't want those because I won't know if the thing works well unless I pay for it. I'm not opposed to paying for a converter IF I know it works awesome on a Mac.

OS X :: Converting Entire Video Library To M4v/mp4?

Jan 27, 2010

I'm sure many people, like me, have much of their video library and collection in various formats other than m4v/mp4. I was wondering if anyone has made the effort to actually convert their entire library of videos into m4v format so that it's all apple hardware compatible or if you have duplicates of everything to preserve high quality 'originals' and lower quality iphone/ipod conversions etc.

Just a simple question of how you manage your video library I suppose. I also wonder if anyone even uses iTunes to manage their videos? It seems with the increasing number of apple devices pilfering our lives (or those of us that choose to let them pilfer our lives at least) could probably do with some simplification of formats.

The video podcasts in the playlist open but dont (and cant) play, although when I drag the progress slider left to right it fast forwards. As I drag and I can see whats the video content.I am on 10.6.3 latest Itunes on Snow Leopard, having fell back to Snow Leopard from Lion yesterday.

These podcasts are mp4 - and VLC plays them perfectly, i have d/loaded Xiph, flip4mac, Mplayer X. Lame and these made no difference.
