I thought quicktime plays .mp4 files

I downloaded quicktime to play a file extension with a .mp4 extension and quicktime says it wont play and there is nowhere to download nothing to make it play. How do I play .mp4 extensions? I tried downloading like 20 programs that are suppose to play .mp4 files and none of them worked.

I have the same problem, When I download video from the net they are mp4. They would play at one time and now they don't. I have qtpro

Can't play .mp4 files anymore

This has nothing to do with an iphone, and ipod or an ipad. My Macbook Pro running Lion 10.7.2 will not open or play .mp4 files any longer.
I've tried opening it in quickview and it shows up as a black screen that never plays.
It does the same when i open it with Quicktime X.
If i try opening with Quicktime Pro 7, it says 'The movie contains some invalid data' 'The movie could not be opened'.
someone please help me, i don't know what's going on, and i'm a video editor, so i need to be able to work with these files like i have been for the last few years

i can dropbox it to you. it's about 107MB
and i don't restart the computer. i shut it down completely and i've tried pressing down Command R and the power button all at once and holding Command R down after letting go of the power button
i've also tried holding down command and r and while they are pressed down, then i press the power button.
none of these tedious combinations have worked.
what's your email and i can send you the file once i have it up on drop box.

HT4609 error -2048 when it doesn't play MP4 file

I thought itunes would play MP4 files, but I got the error -2048, what does this error mean??? with Xp OS
Keep smiling !!!

Yes you'll likely need to re-rip the album to your iPod.
How many songs are reported in your iTunes library?
When you said you selected your entire iTunes library and made sure they were not set to skip when shuffling, how exactly did you do that?
There seems to be a missing piece of information here that would help explain the differences in numbers.

HT3775 why won't quicktime play .mp4?

why won't quicktime play .mp4? I just downloaded a 1.2 gig mp4 video that won't play.

Thanks. I just found it strange that it was one of many files that I ripped from a DVD ( part of a box set of a TV series, and all the others were fine so far. Funny that this one in particular was causing a problem.

Still Cant Play MP4 Files

Hi
The first time I downloaded QT 7.4 , I couldnt play MP4 files in QT and FR. I then had to reinstalled QT 7.3 with Pacifist and it was all okay. Today I downloaded Version 7.4.5 (25) and the same problem cropped up! I thought Apple would have fixed it by now! Anyone else facing the problem? Before installing I had run permissions. I am on the latets verion of Tiger

What's the nature of the files that can't play? Do you hear the audio but can't see the video? Were they converted from .flv using TubeSock or iSqunt? If so, when you download the latest iSquint, it comes with the Debreaker app that fixes those files.
There are other solutions like using Pacifist again or using an old version of a component, but both of those mean that, with every update you'll be doing it again. If your files are of the specific type listed above, that fix has worked through the last few updates with no problems.

My N73 can't play MP4 file

Hi,
I'm using N73 now,just bought it. When I tried to play a MP4 file by using RealOne, it promted "unable to play media file". However, when I move the memory card to another N73, it played well.
My version is V 2.06.... I know there is higher version V 3.0... but I dont think it must be upgraded to play MP4 file.
Can any one help me please.

Btw, the other 2 n73 phones that you used to play the video must have a new firmware, yours is too old!!
You mean the latest FW lets N73 to play DIVX video files without installing any 3rd party software like smartmovie?

Playing mp4 files on iPad

Hi All, this a desperate cry for help before I finally junk my new iPad: I am currently enrolled in an online program running on the Adobe Connect platform. The multimedia files (mp4, pdf etc) can not play on the iPad despite several attempts. Any explanation to this and suggestion on what to do?

You need an app to play those files....I am pretty sure. I play mp4 videos just fine on the app Goodplayer...the older version! The currently available Goodplayer app may not play mp4 files, since they had a dispute (exhorbitant fees) with Dolby, who banned their software use on Goodplayer and several other apps. I understand that there is an app available at the app store that has Dolby software, in that they collaborate with Dolby in some way. Be sure to check capabilities and limitations before you buy any such app. I don't know about pdf files.

Nokia n85 not playing MP4 files

Hi,
I never used the video podcasts, well I just tried to use some nokia video podcasts and they were in MP4 format. To my surprise my phone says it can not play the format and so it just played it as the audio file. I was reading at GSMArena.com and looks like N85 does support MP4 files.
Can any one help me on this? How can I play MP4 files on my phone?
Thanks,
Harpreet

Well, podcasts are mainly encoded in AVC@640x360 or 480x320. N85 plays AVC only at 320x240 resolution or lower. It has nothing to do with the container, in this case .mp4.

Front Row won't play .mp4 files

I just recently started using Front Row and, for some reason, it won't play .mp4 files. The said files are in my Movie folder and show up in Front Row's "Movies" menu, but when I try to play them it says "Selected video could not be played, format was not recognized."
Please help!!

iTunes only supports MP4s encoded using the Main Profile, but many MP4s that you can download from the web are encoded using High Profile. These need to be converted.
You can use an app like VideoSpec or MediaInfo to list the encoding characteristics of your MP4s.

How can i make quicktime play avi. files?

pls..how can i make quicktime play avi. files? because i have some avi files on my ipod or data cd but i can't play them on my laptop. pls help me..
and also, im trying to make a music video but i dont how to select different clips from a movie.

Hello,
You can get from Microsoft, the flip4mac free player. Since Windows Media Player for Mac is no longer supported, this is the way to go.
http://www.microsoft.com/windows/windowsmedia/player/wmcomponents.mspx
In my opinion, it is by far the best solution for playing .avi or .wmv files, because you get all the advantages of Quicktime.

Quicktime is distorting audio while playing mp4 file

Since upgrading my android phone from gingerbread to icecream, any mp4 video files recorded on the device no longer play correctly in quicktime (and iphoto, imovie etc). The video plays fine but the audio is distorted. Older mp4 files prior to the upgrade play fine. I have taken a look at the differences between the file infos and found the newer mp4s state 2 audio channels where as the ones playing correctly only state one. That is the only difference. All codecs listed are the same. The files do play correctly in VLC and DivX but I want to be able to use these movies in slideshow presentations using iPhoto. I am using Lion and all software is up to date and I have perian installed. Any suggestions as I have searched the web high and low and no help??
Thanks.

If i run the adobe AIR application on Win 7 host, i see the same failure.

Cannot Play MP4 Files on Front Row and Quicktime

Hi guys,
I cannot play any MP4 files on QT or FR. They play fine on VLC which is strange as I never had a problem before. I have the latest version of QT and didnt repair permissions on upgrade!

Panther: http://www.apple.com/support/downloads/quicktime731forpanther.html

Can't play MP4 files

Today after i downloaded some MP4 files at first it was telling me so and so mp4 file is not a valid win32 application after uninstalling and reinstalling quicktime now when I try to play the file only like a quarter of the quicktime window even shows and it plays like 3 seconds of the audio without showing any video and says quicktime has stopped working and then the close program dialogue box shows up I have the latest version of quicktime installed. Does anyone have a solution?

Slapping myself w/a wet noodle across both cheeks!
Was so busy checking out the actual video & its codes I missed the other video download options in the left corner. Sowwy!!!!!
I downloaded the 64Kb MPEG4 (105 MB) & the 256Kb MPEG4 (169 MB) videos. Repaired permissions after the download.
At first the 256kb refused to open. Got some funny error message. So I played the 64kb video-----no problem. Got sound & video coloration was pretty good. No green discoloration.
Went back & tried the 256kb video again & this time it opened up w/o any problems. The video had both sound & picture. Same as above.
Played around w/the FF buttons on both videos & no problems with that either. QT did not crash.
"plays sound but video is green."
To be quite honest, I have no idea what would cause a dicoloration like that in QT.
See if repairing permissions & restarting helps. If not, trash QT preference & restart.
Home>Library>Preferences
Trash the com.apple.quicktimeplayer.plist file. A new one will be recreated on you open QT.

You didn't answer probably the most important question: whether you're using hardware or software Mercury Playback Engine (MPE). However, since you've set Maximum Render Quality on, it's largely irrelevant.
When you're using hardware MPE or have the MRQ flag set for your export, rendering is performed with linear color. Linear color processing affects how color channels and alpha channels are composited--anything less than 100% opacity is subject to linear color processing. Check out this article for more information on linear color/linear light: Linear Light - Artbeats
Since it sounds like you're seeing the results you expect in the Program Monitor, but not export, I'll wager you're not using hardware MPE. Only by disabling the Maximum Render Quality flag on export will you be able to get results that match what you see in the Program Monitor (within reason, of course). The only way you could see the effects of linear color within Premiere would be to either use a qualified GPU that enables hardware MPE, or go into your Sequence Settings and check the "Maximum Render Quality" option and then render previews.
Please let me know if that helps resolve the issue, or at least provide a little insight into the problem.
