Colors reversed in QuickTime MP4 videos.

Colors are fine if I open .mov files with QuickTime, or if I open MP4 files with DivX, but the colors are reversed if I open MP4 files (loaded from my Kodak camera to Kodak Easy Share on my PC) with Quicktime or Realplayer. Tried updating both programs, but nothing changed. I'm baffled. Help would be appreciated!

Thanks for all your help, and I hope you aren't freezing down there in Christchurch! I have a couple of online friends in NZ now (discovered when I was watching the lost Emperor Penguin "Happy Feet" last year) and they recently sent me a link to a YouTube video of the KiwiRail train plowing snow in Arthur's Pass. Looked like the kind of snow we get here in Michigan, but, of course, not in June, and we don't have mountains. Right now, we're roasting in 90-degree F temperatures.
Anyway, my attempt to bring in the videos on my 93-year-old father's computer was frustrating, but it isn't the type of problem you (or anyone) can solve. First, I arrived at Dad's house and grabbed his camera, only to discover that he had given up on ever being able to transfer the videos to his PC and had deleted them all! :-(( Then I waited while QuickTime downloaded, but soon realized that it was only updating QT 6, not installing QT 7, so I had to start over. By then, we had discovered that Dad has some other program (I can't recall the name of it) that would open the MP4 videos, but he wanted QT because he likes being able to cut off the beginning and end of the video to pare it down to the parts he wants. After I had downloaded and installed QT 7, I was horrified to find that this version will not do that kind of editing unless we buy the Pro edition, which Dad isn't going to do. So I had downloaded a version of QT that he doesn't need and that actually does LESS than he could do before. He kept begging me to find a way to retrieve the old version of QT, but I don't think it can be done. I think we're stuck with the new one. That's disappointing because many of our videos are of animals, and that usually involves a lot of dull time on the video before and after the animal does something interesting.
Not real happy with Apple right now. :-( But thanks for all the guidance anyway. Take care and stay warm!

My Quicktime Mp4 Video Archive is Converting into Sound Files

I archived a number of videos using quicktime, in mp4 format. I don't know if this was caused by a software update; but, these videos only play as sound files now. This has happened on quicktime videos stored independently on both of my Macs - so I don't think it is a problem with one of my computers.
I must not be the only one who has experienced this problem. Does anyone know what to do about it?

Thank you for the prompt response to my question. I opened up the "Movie Inspector". I don't see where it says "codecs"; but, is says:
Format: H.264, 320 x 240, Millions AAC, Stereo (L R), 44.100 kHz.
FPS: 29:97
Playing FPS: (Available while playing.)
Data Size: 5.72 MB
Data Rate: 739.14 kbits / s
Current Time: 0:00 01:04.93

I hope that helps . . . Again, thank you for your reply.

Please help, I am trying to split a HD mp4 video into two parts using Quicktime 10.2

Please help, I am trying to split a HD mp4 video into two parts using Quicktime 10.2, running Mountain Lion. I use trim then export but it doesn't give the movie option as a format. What would you suggest i do?

I'm not sure why you're using a FAT32 drive, but using ExFAT instead of FAT32 would be a better overall choice as it doesn't have the 4 Gig limit.

MP4 Video Playback in PSE8 & Windows 7 Without Quicktime

I have several MP4 videos that play fine natively in Windows 7 with Windows Media Player (no codecs have to be installed/downloaded). However, PSE8 tells me I have to install Quicktime to play these files and generate thumbnails. Is there any way to tell PSE8 to use Windows Media Player or the built-in codecs for this?

Yeah, hard to believe, but Adobe technical support has gotten even worse in the last six months. It got so bad after they outsourced/offshored it that an Adobe VP published an open letter to customers in August that was published across the Adobe site. It's no longer available at Adobe.com, but you can read it here:
http://www.macworld.co.uk/blogs/index.cfm?entryid=806&blogid=12
I've seen no evidence that things have gotten better, and some evidence that it's gotten worse. The support for PSE prefaces each reply with "sorry for the delay, we're overwhelmed", and they acquired a bad habit of arbitrarily marking cases as withdrawn (something only the customer should do), preventing customers from replying and preventing an email notification from being sent to the customers.

Is there a way to store mp4 video files on iCloud that can be read by either QuickTime or ITunes?

Is there a way to store mp4 videos in iCloud so that they can be accessed by my IPad using Itunes or QuickTime. I'd like to travel with only my IPad.
Many Thanks

Yes, there are some apps that will use your iCloud storage to give you access to video. There are also other solutions such as You Tube, Vimeo or Dropbox. Apple doesn't provide any of it's own solutions for keeping video in iCloud.

I am trying to play a MP4 video on quicktime on my PC and the video comes up, but not the audio

I have a MP4 video I am trying to watch on Quicktime and the video plays, but not the audio. Is there a certain Plug-in that I need? I have a new PC with Windows 7 professional Operating system.
Please advise

Can Quicktime Pro convert .mkv video formats to mp4 video formats

I purchased Quicktime Pro believing it could convert .mkv video formats to MP4 video formats, however, the resulting output file is just a 60kb file from an original 971,936 kb file.
I registered the key as given to me in the purchase receipt email, I used Export to MRP, I selected the input .mkv file. All seemed to be OK until it ended creating the short 60kb file.
Suggestions please.

As indicated on the Apple web site, keying the QT Player for "Pro" use merely unlocks editing and conversion features built into the app but not available without the key. It does not add any new file type or codec support beyond that for which the QT Player is already configured on your platform.
I registered the key as given to me in the purchase receipt email, I used Export to MRP, I selected the input .mkv file. All seemed to be OK until it ended creating the short 60kb file.
An MKV file will convert only if you have support for both the MKV file container (which is not natively QT compatible) and codecs to handle the specific codecs contained in the MKV file container if available for QT use.
Suggestions please.
I do not normally use MKV files on a daily basis and so, on those occasions when I do need to use them as a source for conversions to mobile devices, I use the free HandBrake application. As I see it, you can either try to add the missing support needed to use QT 7 Pro or you could download HandBrake for iTunes managed/mobile device files or use FFmpeg (on which HandBrake is based) for more general target conversions. As a non-PC user, I am assuming here that the Windows versions of both the HandBrake and FFmpeg apps have the same features as are available in the Mac versions of these apps.

How do I Ensure that your MOV/MP4 video is exported through QuickTime conversion?

I have a YouTube channel. I use Sony Vegas to render my mp4 projects, but my PC uses QuickTime & I'm VERY unfamiliar with it and/or how it works, how to access it. When I record a mp4 video, QuickTime needs to be involved, but I'm unsure how to even check or know where to go, to find out how to do that. I need ensure my mp4 video is exported through QuickTime conversion. I have no idea what it even means? Does anyone out there happen to have the knowledge I would need to check if in fact the video is being exported through QuickTime conversion? If so, I WOULD FOREVER BE IN DEBT TO YOU! I hope someone can help me figure this problem out. Thanks for taking the time to view my question, and if anyone does know, I'd greatly accept your advice! Thank you very much again!

Hello,
You can do this: Set up a slow pulse train for CTR0 (1Hz). Set up a continuous digital channel read for Port 0 Line 0 on your card. Hook up CTR0 output (pin 5) to P0.0 (pin 10). Start your program to do the counter output pulse train and continuous read. You should see your digital line transition from high to low over time. The examples you can use to set this up are Gen Dig Pulse Train-Continuous.vi and Cont Read Dig Chan-Int Clk.vi. For Cont Read Dig Chan-Int Clk.vi, remove the DAQmx Timing VI to make it software timed, and connect the task handle and error wires accordingly. They can be ran from separate VI's as they don't use the same resources.
To be exact on the verbage used, you can perform a self-test on the device by right clicking the device in Measurement and Automation Explorer (MAX) and select Self-Test. As for testing the device manually, go with what I described above.

MP4 video without video

Hi, I have buyed a MacMini in USA but I'm from Italy.
When I try to see my MP4 video done with my Samsung Flashcam (PAL), I can ear the sound but I can't see the video.
There are many pixels with different colors.
This because Quicktime USA (version X) come only with NTSC and my video are in PAL format ?
How can I resolve this problem ?
Thank U
Luka.

Unlikely to do it unless the avi is using all mp4 codecs and just needs repackaging.
MPEGStreamclip is possible. Try "save as" and see if it works. If not you may be able to get by with just converting one of the components and passing through the other if it is a mp4 variant.
Use Media Info - http://mediainfo.sourceforge.net - to get details of codecs used in multimedia.
Many AVIs use mp3 as an audio codec so that one at least will need converting.
If you end up having to convert, some use Handbrake.

How can I make iDVD with a H264(.mp4) video file???

I've got two files which is in .mp4 format, I tried to edited it in iMOVIES but it came up with only audio no video. So then I tried to put that two .mp4 video directly into iDVD, but it also didn't work. There is no problem when I try to view .mp4 file in quicktime player.
So if I have to changed the format to .avi , which software would be best?? I want to keep the quality of the original files but I have heard so many times that after changing the file format, the quality may not be the same as before.
Please, masters, help............

OK, here are the results of my experimenting:
ffmpegX wasn't happy making the conversion and froze. I didn't try 'playing' with it to make it work. I guess I can't recommend this approached for you.
I DID have success creating a DVD from your file using Roxio's Toast Titanium 7 (you must have version 7 to do this).
It was a slow process - your 0:03:46 clip required abount an hour on my 1.33 G4 PowerBook. The process might have been slightly slowed because in addition from going from MPG-4 to MPG-2 (and converting the audio), it was also converting from PAL to NTSC (the source video is 25 fps).
In my opinion, the results looked pretty poor when viewed on a TV. About what I'd expect starting with a small (662x384 pixel), highly compressed MPG-4 image file.
Stick to viewing them on your computer with the VLC Media Player. You'll be a lot happier.

Photoshop wont open .mp4 video file

I have photoshop CS5 extended which as far as i know should be able to open .mp4 files.
Any ideas?

Can you actually open and run the file in Quicktime?
Could you be missing a codec?

Mp4 Video on a iPad

Hi there,
I have the following problem. I have integrated into Captivate 8 a short video sequence in a slide. The Project is published as HTML5 file incl. Scorm 2004 Revision 4 in ILIAS LMS.
This all works great so far. I can see the video sequence on the iPad to play but only for one time. When the Videosequenz is finished the small panel in the video window can then no longer use.
My question are:
- Does anyone happen to have the same problem?
many greetings
Jochen

Wedding video was shot with iPad. MP4 video file was emailed to family member with PC. Family member can't view MP4 file in iTunes or Quicktime or Windows Media Player. How can we open and view this file?
If files don't play in either Apple or third-party media players then I would normally suspect that either the file containers or file data was corrupted during the transfer/email process. The H.264/AAC content recorded by Apple mobile devices should be compatible with any media player capable of playing MPEG4 AVC standard JVT project partnership files in MP4, M4V, or MOV file containers.

Possibility to assign a color profile in the color management tab for more video formats

Presently, in After Effects CS5, in the color management tab of the "Interpret Footage" dialog box the possibility to assign a color profile to footage is grayed out for many video formats.
Formats that allow to assign a color profile include Quicktime/JPEG2000, Quicktime/Motion JPEG A, Quicktime/Motion JPEG B, Quicktime/MPEG-4, Quicktime/Animation as well as various image sequences, like tiff-sequences. (Motion JPEG A,B and Quicktime/MPEG-4 are not very helpful in this context because they have a small color shift when reimported to After Effects.)
Formats that do not allow to assign a color profile include Quicktime/PhotoJPEG, Quicktime/H264, H264 main concept, DVCPRO HD 1080p30, F4V. (Here, H264 main concept has anyway the disadvantage that it has a color shift when reimported into After Effects.)
In After Effects CS4 it was possible to assign a color profile to Quicktime/H264, Quicktime/PhotoJPEG, DVCPRO HD 1080p30, but in CS5 this is no longer possible.
Those video formats that do not allow to assign a color profile automatically are interpreted as having the color profile HDTV (Rec. 709) Y'CbCr in case that the videos have 1920x1080 format; similar applies to PAL formats which get SDTV (Rec. 709) Y'CbCr color profile.
(I did not find anything of this automatic assignment to HDTV or SDTV color profile in the "interpretation rules.txt" file, therefore it must be written into the programme itself.)
With growing popularity of wide gamut monitors it becomes necessary to produce footage and other videos that have a color profile different from HDTV or sRGB. When such footage is reimported to After Effects it has the wrong color and the only workarounds are either to use (in After Effects) the effect "Color profile converter" which necessitates extra render time or to use somewhat unpopular formats, like JPEG2000 that has very large filesize.
Presently many footage is produced in Quicktime/PhotoJPEG and therefore it would be very desirable to allow to assign a color profile to such footage in the color management tab of the "Interpret Footage" dialog box.
Does anyone know why in AE CS5 the video formats Quicktime/PhotoJPEG and Quicktime/H264 do not allow to have an arbitrary color profile assigned (although it was possible in CS4), is it a bug, or does it have a deeper reason.
In this context I have a related question, often I read that Quicktime videos have a gamma tag. Does this mean that part of the color profile (the gamma value) is actually embedded/remembered, like you have it for images where the gamma is part the embedded color profile.
I use AE CS5 on Mac Pro 2009 with OS 10.6.7.
Thanks,
Volker

Thank you Rick for this interesting explanations and the links to articles.
In the past few days I performed a few tests in After Effects and it is interesting that you mention that cameras, like the Sony EX3, allow videos to have embedded color profiles. I am not working myself with cameras but either get footage from the internet or sometimes videos from our video department which produces videos with professional SONY cameras, usually I get them in a matrox mxf format.
As far as my test with After Effects show it is not possible to embed color profiles in the videos rendered with After Effects. Independent of the color profile in the working space and independent from the color profile in the output module I always get the same reaction if I reimport videos rendered by After Effects back to After Effects:
In AE CS5 videos made in the formats Quicktime/PhotoJPEG, Quicktime/H264, H264 main concept, DVCPRO HD 1080p30, F4V are always interpreted as color profile SDTV/HDTV (Rec. 709) Y'CbCr (even if I made them in other color profiles, such as Adobe RGB, Photo RGB, sRGB); and there is no possibility to change this interpretation rule.
In contrast videos made in the formats Quicktime/JPEG2000, Quicktime/Motion JPEG A, Quicktime/Motion JPEG B, Quicktime/MPEG-4, Quicktime/Animation are always interpreted as sRGB (even if if I made them in other color profiles, such as Adobe RGB, Photo RGB, HDTV); only this time I can change the interpretation rule. Therefore if I know for example that if I had selected Photo RGB in the Output module I can change after the reimport the interpretation rule from sRGB to Photo RGB and only then I get again the original colors.
The only exceptions are picture sequences, such as tiff-sequences, where the original color profile is automatically selected in the interpretation of the footage.
Therefore, unfortunately for videos produced by After Effects your advice "If it says something like sRGB and you can change it, in most cases you shouldn't change it because the guess is probably right. If there is no color profile assigned then you should assume that is correct." is not so easy to be applied. You have to know how you did it originally in the Output module and hope that you can change it to the proper color profile, in case that the original color profile in the Output module was different from sRGB and HDTV/SDTV. But it is interesting to hear from you that with cameras there seem to be more possibilities.
For this reason it would be nice if in future versions of After Effects one could change the color profile in the the color management tab of the "Interpret Footage" dialog box also for formats such as Quicktime/PhotoJPEG, Quicktime/H264, H264 main concept, DVCPRO HD 1080p30, F4V.
Of course one can always circumvent shortcomings by using tiff-sequences, QT/jpeg2000, or QT/Animation as formats for storing, which is anyway better for lossless or nearly lossless storing, but the files are then too large and also cannot be played easily with a player.

Embedding mp4 Video

When we embed mp4 videos into a web page they run fine on
MACs but will not run on IE. They also run on Foxfire. What can I
do to make this work on IE?

Are you sure you have the appropriate codec for IE? If you
are successful running it on Firefox and Safari most likely
Quicktime codec is being used, if IE is set to windows media
player, you may want to download the appropriate codecs.

1280x720 mp4 videos stop playing video after 9.1 update, only sound works

After upgrading to 9.1, 1280x720 mp4 videos won't play video anymore, only sound. Any help?

I am having a similar problem with videos. After an update, some of my video files play and others do not. They are all in mpeg-4 video format so I don't know that is the difference except the videos that are not playing are larger files of movies. The shorter videos play fine. Any ideas? My quicktime is up to date and I'm using iTunes 9.1. Before updates I was able to view the videos without a problem.
I am guessing that because of the size of the videos...mine are 640x352 that does not play but 480x320 will play
