Can't play MP4 videos in Quicktime

Hi,
I have uploaded some videos from my camera to my iMac. They are in the MP4 format. When I am in the Finder, I can preview the video and I am able to see video and sound...But when I double click and open in quicktime, then it only plays sound with no video. I also tried to open the video in Final Cut Pro, but it doesnt recognize the file.
Any solutions??? Please respond asap- THANKS!

Download a copy of MediaInfo Mac and tell us what codecs are being used. MP4 is less of a hold-all wrapper than AVI but maybe there's something strange in the video codec.
Also try:
[Perian codecs for Quicktime|http://www.perian.org] - plugins to add functionality to Quicktime for playing additional audio and video formats
[Quicktime audio problems, Perian, VLC|http://discussions.apple.com/message.jspa?messageID=9013669] - read note about uninstalling prior DIVX support before installing Perian.

Can't play this video on Quicktime X but works on Quicktime 7

I am having this same problem. I believe everything was working fine before I installed Lion the other day. The thing is, I also installed Final Cut Pro X (Previously had Final Cut Express installed), and so I am not sure what screwed up my ability to play this video. ere is some information, I would appreciate any help anyone can give:
I cannot play m4v files in iTunes or QT 10.1(501). I was not sure how to install just Quicktime, so I re-installed all of Lion and still does not work.
VLC and QT 7 play the file just fine.
I have tried installing the latest version of Perian, still will not play
I have uninstalled DivX and I don't see any particular other video codecs installed.
Compressor 4 loads the file and can play it fine
MPEG Streamclip plays the file fine
QT 7 reports format as "MPEG-4 (Perian)"
QT 10.1 reports format as "mpeg4"
VLC reports Codec as MPEG-4 Video (mp4v)
In the log I get this when I try to click the play button in QT 10.1:
7/23/11 12:46:44.154 AM QuickTime Player: AudioConverterNew returned 'fmt?'
7/23/11 12:46:44.155 AM QuickTime Player: Prime failed ('fmt?'); will stop (48000/0 frames)
7/23/11 12:46:44.156 AM QuickTime Player: AudioConverterNew returned 'fmt?'
7/23/11 12:46:44.156 AM QuickTime Player: Prime failed ('fmt?'); will stop (144000/0 frames)
Here is a link to one of the files: http://dl.dropbox.com/u/14091323/Intro.mov
If your Lion QT 10.1 can play this file let me know, and if so why it can play (did you install a special codec?), or if not and you know why it doesn't play please let me know.
Very frustrating. Does anyone know where I can download the QT 10.1 that comes with Lion to try to re-install just that? I also tried to Repair Permissions.
Thanks for any help!

I came here as I'm having trouble playing back MPEG4 files using Lion. I tried your file - clicking it plays fine in Safari, but downloading and opening in Quicktime X will not play (however if I drag the slider and scrub through it, I can see every frame, it just won't play.)
This is on a clean Lion Server - only video thing I've installed is VLC and that was because I was having issues.

Why does Quicktime tell me it can't play certain videos created with my Phantom 2 v3 drone ? I fly it and switch back and forth from video to still pics and while I may have filmed four videos sometimes Quicktime tells me that one of them can't be pl

Why does Quicktime tell me it can't play certain videos created with my Phantom 2 v3 drone ? I fly the drone and switch back and forth from video to still pics and while I may have filmed four videos , sometimes Quicktime tells me that one of them can't be played . Checking the info shows that each of the unplayed videos was saved in the same mp4 format as the playable ones yet some of my most important videos won't play . It's getting very frustrating .

first; I use Perian, that helps even though it is no longer supported, (must have for avi files)
the apple-cores at apple have gotten very sloppy -- quicktime is a bit finicky and flakey.
example,   occasionally (when copy file from quad's card to hard drive) the avi will show up as a 'mov' file and qt plays it no problem and no conversion.
but that is very occasionally, most of the time qt won't convert the file,   -- iMovie won't open an avi without Perian installed , I don't know how that effects qt.
qt 7"pro" is no good either, (qt 10 does everything it does and for NOT the extra $35)
I have gone to VLC and MPlayerX for direct playback for drones and cameras.

Quicktime Pro 7.2 Can't Play Lynda Videos Chris Orvig

Hi,
I can't play Lynda videos from "Photoshop CS3 for Photographers" with
Chris Orvig.
They all have the .mov extension. Quicktime Pro gives an error msg,
"error -2048 Couldn't open the file <XXXXXFILENAMEXXXXX> because it is
not a file that Quicktime understands".
I tried Windows Media Player and Media Player Classic from K-Lite, but
neither can play it either.
All my other videos are playing ok. After the error I installed every
codec from K-Lite Codec Pack Full.
It's still not working.
How do I fix this, where do I find a patch?
I've sent an email to Lynda technical support.
Windows XP Pro SP2
Quicktime Pro 7.2
K-lite Codec Pack Full - All Codecs Installed
Windows Media Player 9

I can also verify this (QT Pro 7.2 exporting to .mp4 not compatible
with video iPod [firmware 1.2.1 on both 5G/5.5G units]).
This results in the unusual situation where custom H.264 output
is operable on the iPhone but not the iPod.
Example: your iPhone should play
http://homepage.mac.com/retiarius/sample.elements.mp4
but it won't transfer to a video iPod.
Yes, the workaround is to 'export for iPod' or do the conversion
within 'iTunes', but this in many circumstances will generate
larger files.
The closest description of this situation is:
http://lists.mplayerhq.hu/pipermail/ffmpeg-devel/2006-September/015930.html
Perhaps Apple will release a video iPod firmware update soon
to get the 'uuid' atoms and whatever watermarking they are
using these days straightened out.
I'm surprised this hasn't been noticed more by video podcasters
who dutifully use Apple's own QT Pro encoding tool to optimize
filesizes via the tunable H.264/.mp4 codec settings.

How can i play encrypted video(.mp4) in iphone app?

Hello,
I want to play encrypted mp4 video in my app.
How can i play encrypted video in iphone app?

Thanks for your assistance. Unfortunately I'm still not able to get this to work.
First, I don't see an export to Quicktime in AppleTV format setting. The only choices that I have are export to Quicktime in Full, CD, email or streaming video format.
I tried both full and CD but I still cannot get it to my AppleTV. Once the video is in Quicktime format I drag and drop the file into my iTunes library. It shows up in the movies directory on Itunes but when I sync Itunes with Apple TV - nothing. Everything else syncs but just not the quicktime movie.
Any ideas?

I can't play certain videos from the internet on my macbook

I can't play certain videos from the internet on my macbook.
When using Sarfari or Google Chome, I am unable to play some videos on the internet. News clips, posted videos on blogs, and tv episodes from their own network websites. Youtube videos are fine. I doesn't make sense.
I tried downloading an update for quicktime, but the computer claims that quicktime is up to date. Yet, the videos and tv episodes don't play.
I have checked for the most recent software updates, and everything is up to date. Nothing is wrong with the hardware either.
Any suggestions would be awesome! Thank you!

In addition to Flash, you might need some other plugins. Microsoft videos are mostly in Silverlight, and you'll want Flip4Mac to play WMVs. Perian contains codecs for pretty much every video online.

Thanks

I dont know whats wrong. I have all the latest updates. Does anybody know whats the solution and why after a reinstall I would be experiencing this problem.

Hi-
Referring to this post:
"The AIC codec is installed by iMovie HD and is just what its name implies. Intermediate (temporary conversion from one file format to another).
Your G4 will not be able to play the file past a few frames per second because of the large dimensions and high data rate even if you did find the codec. You'll find editing it using QuickTime or iMovie a frustrating experience because of those facts."
I'm a little confused-- do you mean that the G4 computer is just not strong enough to edit HD files "even if I did find the codec"? I was planning to edit it with Final Cut Pro (have never edited a HD project before), but is my computer not adequate? Let me know if there is any way for me to tackle an HD project with my current laptop-- otherwise I guess I really need to look into a new one.

I cannot (anymore) play a song on iTunes, nor can I play a video, ie. You tube.

I cannot (anymore) play songs on iTunes, nor can I play a video, ie. You Tube.

I have done a google search, and I used a suggested fix by going to Quicktime; Preferences); Quiktime Player; click on audio source; close Quiktime and iTunes; restart. It then works for both iTunes song and You Tube video. But when I restart the computer, it no longer works.

I have a gmail account and someone sent me a video. How can I play the video message on my ipad?

I'm new to ipad. I received a video message in gmail. How can I play it on my ipad?

Leslie-
The iPad can not play some video formats such as WMV or FLV. Those would need to be converted on your computer to something the iPad can play, like M4V or MP4.
You might ask the person who sent the message to you to do the conversion and send it again.

How can I play multiple movies on quicktime like I can on windows medplayer

How can I play multiple movies on quicktime. When i click on open file it will only let me choose one movie to play.For example When ever I used windows media player I could drag my mouse over numerous files and it would play them one after another like in a list format. Can anyone help with this?
Thank you

Hi Brennan,
Only HDMI is going to support audio & video on the single cable. Which MacBook Air do you have? Here's a great article regarding this - http://support.apple.com/kb/HT4241. Also keep in mind that only the current generation of MacBook Airs support this. The previous generation, also with MiniDisplay Port would support HDMI but you'd need to run a separate line from the headphone port over AUX for audio.
The first and second generation models, which have micro-DVI, do not support audio. Regarding the RCA cables, Apple offers adapters that allow you to go to VGA and that would probably be your best bet. I do not believe there's a MiniDisplay Port to RCA solution out there, you'd need to do multiple adapters and that's always a questionable performance solution.

Can't play the video in my Lumia 520

Hi
I always love the work of nokia and this time trailer app is just Nice but there's a problem.
I have downloaded 6 trailers and only 1 is able to play.
Rest of them says "sorry we can't play this video on your phone".
I have no idea what's wrong with my phone.
Please help.
I have a Lumia 520.
Thanks in advance.

Hi @livinglife,
Welcome to Nokia Support Discussions!
What is the error message displayed when you try playing the video? Have you tried using mobile data? If yes, does it show the same issue? What fixes have you tried so far? By the way, are you using the same phone model?

Can I play home video on my ipod touch?

Can I play home video on my ipod touch?

So, the only way to watch home video in ipod touch is via itunes? Because in fact i'm trying to use my ipod touch as a video monitor for my DSLR camera while i use it for filming. I thought i could use the hdmi adapter for ipod touch, but everyone tells me that it might not be possible, so i wont buy it without knowing if it is possible or not. I wonder if it is phisicaly possible, so all we would need for that is someone to develop a softare to use the hdmi adapter to watch a video into an ipod. I say this because my camera has a hdmi video out, but it could be with simple RCA cables too. Someone think it is possible?
