Importing m4v - no thumbnails

When I import m4v's into a new iMovie event, everything seems to go OK, but the event shows no content. When I look at the event in the finder, there is lots of stuff there, but one thing seems to be missing: each event folder has an "iMovie Thumbnails" folder and in "good" events that folder contains a QT movie; in the "bad" events, the QT movie is missing.
One time when I was fiddling around, iMovie all of a sudden popped up a little window saying it was generating thumbnails, and then the event showed the content.
How do I force iMovie to generate the thumbnails for an event?

For anyone else (like me) who winds up here, here's the solution to this problem...

Correct Procedure To Import m4v Into iTunes

Hello, what is the correct procedure to import m4v movie files Into iTunes so that I can watch them on my iPad? Nothing seems to work...

Gee, that makes total sense. Wonder why the fine folks at Toast didn't think of that when selling the concept of making an iTunes export from your MPEG4 (H.264 AVC) video project? Glad I didn't upgrade from 10 because there doesn't seem to be improvement in 11 for this issue.
I'm testing the theory floated here and stated from Apple that in order to be accepted into the "new" iTunes each video has to specifically be coded in QT Player or iMovie to render in multiple formats (iPod, iPhone, iPad screen sizes). I have a number of videos I made (in iMove) that apparently were natively made in this way (in the background). However most video made by others are clearly not (simply in a single format, that's specified). The player product doesn't downconvert is another way of saying it. iTunes will play out to any of their products if the file is accepted into iTunes (e.g., created properly with multiple formats embedded).
If Toast does know this, how many others are there claiming to make compatible uploads that really don't. Seemed like Toast used to be the end-all of compatible (plug and play with Apple and many others) apps.
IMO, if true, this is a shortcoming of the process of using your own videos in iTunes (not a copyright issue) and greatly extends the time needed to import those projects. It actually restricts legal uses to being made in iMovie or converting in QT. Convenient for nobody...

Why won't ITunes 10.5 allow me to import m4v's anymore?

Before my computer crashed and was set back to factory settings, I had an older version of Itunes, 7 I think. I regularly converted videos to m4v files that I could then drag and drop into Itunes playlists or a playlist on my IPod. After the crash/repair, I installed Itunes 10.5, but now I cannot import m4v files. ITunes gives the error message "some files, including "(file name)" were not copied to the iPod because they cannot be played on this iPod". By "some", it means "none". I'm doing nothing different than I previously did. Why won't the files go to ITunes or my IPod anymore? Any assistance is appreciated. Thanks in advance!

I am having the same problem with a a new iMac running Mountain Lion.
However, I was able to add a .m4v just fine. Could it be that iTunes no long accepts .mov's?! Ridiculous!

Since updating iTunes and Mavericks, every time I import m4v files into iTunes it renames all the files to "Avidemux". what's gone wrong?

Since updating iTunes and Mavericks, every time I import m4v files into iTunes it re-names all the files to "Avidemux". what's gone wrong?

(By the way, would I need to use also the red and white phono cables also to get sound?)
Yes, S-video cables do not carry sound.
When you import 16:9 into DV Widescreen, make sure that you have UNchecked 'automatic letterboxing'.
In Preferences, is the project set to the correct standard?
29.95 fps = NTSC
25 fps = PAL.
BTW, this is actually the iMovie 5 forum, but no matter!

Why cant I import M4V or FLV files into my I-Movie video? Please HELP!

I just got the new Mac Desktop and REALLY hate that I cant drap and drop videos into the newer (i-Life11) -Imovie like I was used to since 2010. Seems to only work for photos. Is there a way around that?
So I am making a church youth group video where I have spent HOURS trying to get parts of Youtube videos into the video to show them. I have 2 forms saved on my desktop thanks to the software - i have a FLV video and a M4V - both converted. The Imovie already has plenty of clips that are M4V in them so I know it will take that form. It just wont let me import them..they are there but are not accesible (they are 'faded') under the File/Import/Movies/Desktop or File/Movies/RealPlayerDownloads. They aren't darkened and and I cant do anything with them.
What am I doing wrong?
HELP please. Thanks for input.
Frustrated volunteer who has spent too many hours on this!!!

Use MPEG Streamclip to convert them to DV. In the case of the FLV file, this requires installing Perian.

Importing M4V - I get audio but only white screen

I've imported a very large m4v file into iMovie (33gb) which was ripped from a DVD using Handbrake.
I get the audio with no problem, but the picture is white - I get nothing at all, the timeline marker moves across as normal but the preview window is white.
I downloaded the x264 codec to try and combat the problem, but I still get the same.

The file I was using was created by Handbrake (ripping a chapter from DVD).
For some reason, when I had the output quality setting (on Handbrake) at 100% the videos won't show up in Streamclip. When I reduce the quality (or leave it at the default setting, which is usually about 60%) the files are working fine.
If someone can tell me how to maintain 100% quality in Handbrake, and still have Streamclip recognize the video, that would be great.
Hope that all makes sense

Importing into iPhoto - thumbnails but no full-size pics

I'm setting up a new iMac with OS X Lion (10.7.2) and iPhoto '11 (9.1.5).
I've Imported to Library over 1,000 photos from iPhoto '08 (7.1.5) from the originals folder. They show up fine and I can see them as Events (after autosplitting) and Photos but when 1 choose one and click on it, I see a black screen. At the top is the date taken (top left) and on the right 6 of 6 (for example) showing how many are in the event. At the bottom are the thumbnails. When I show information, I can see how it was captured, the pixels and the file size plus a photo number and a date. When I resize with the zoom bottom left , I can see a thumbnail of what is happening but no full siz photos.
Can anyone suggest what is wrong or what I am doing wrong?
Thanks in advance for the help you may be able to offer.
John

There are several possible causes for the Black Screen issue
1. Permissions in the Library: Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Include the option to check and repair permissions.
2. Minor Database corruption: Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild.
3. A Damaged Photo: Select one of the affected photos in the iPhoto Window and right click on it. From the resulting menu select 'Show File (or 'Show Original File' if that's available). Will the file open in Preview? If not then the file is damaged. Time to restore from your back up.
4. A corrupted iPhoto Cache: Trash the com.apple.iPhoto folder from HD/Users/Your Name/Library/ Caches...
5. A corrupted preference file: Trash the com.apple.iPhoto.plist file from the HD/Users/ Your Name / library / preferences folder. (Remember you'll need to reset your User options afterwards. These include minor settings like the window colour and so on. Note: If you've moved your library you'll need to point iPhoto at it again.)
If none of these help:
As a Test:
Hold down the option (or alt) key key and launch iPhoto. From the resulting menu select 'Create Library'
Import a few pics into this new, blank library. Is the Problem repeated there?

Automatic Import and "Generating Thumbnails"

I just installed imovie 08, and I have a couple of problems/questions.
1) When I start the Import Process, the Toggle that selects for Automatic or Manual import, goes to Manual and I can't change it..???
2) After some video is imported the computer takes a long time "generating Thumbnails". This never happened with iMovie HD.
Any comments, advice?
Thanks.. Gil

2) After some video is imported the computer takes a long time "generating Thumbnails". This never happened with iMovie HD.
After importing the video, iMovie '08 creates a tiny movie showing the same frames as the imported video, but in a much smaller frame. Those are the "thumbnails". This movie is used for skimming.
iMovie HD didn't offer the skimming feature so it didn't need to build these thumbnails.

Importing m4v to iTunes

I recently downloaded a movie and converted it to a m4v in Quictime Pro. When I try to drag/drop it into iTunes nothing happens and the movie does not import. I also tried File--Add File to Library and nothing happened. Any help for this problem?
Thanks

That WON'T convert it.
If I do the same with an MP3 and change the extension to JPG, it DOESN'T make it a picture. It makes it unusable.
Change it back to AVI and download "Handbrake". http://handbrake.fr/
Use HandBrake to "convert" it to M4V.

Impossible importer .m4v dans ibooks author

Bonjour
Je suis dans l'embarras, impossible d'importer un fichier vidéo .m4v converti par Quicktime 10 ou par Final Cut pro X...
toujours le même message : Le fichier multimédia "xxx" n'a pas été ajouté. Une ou plusieurs pistes vidéo ne sont pas gérées. Votre livre n'a pas été modifié.
OS Lion re-installé, iBooks author re-insatllé... J'ai FCP 7 et FCP X insatllé sur la même machine, on dirait qu'il n'arrive pas à avoir accès à un codec, ou qu'une autre appli squeeze le codec...

Dernière info : je peux lire un fichier .m4v intégré dans un fichier iBooks author à condition qu'il ait été importé sur une autre machine. C'est vraiment l'import qui est impossible : le message apparaît à chaque fois que je tente de glisser le fichier vidéo .m4v sur une page de l'appli...

Importing m4v files in AME fails....help?

Hi,
I have a problem that I have been unable to solve after months of trying. I'm desperate for an answer or any help someone could provide.
I am using Mac Handbrake (Version 0.9.5 x86_64) to covert a few unprotected DVD's to .M4V (with video Codec: H.264).
I am then trying to bring these files into AME CS5 (Ver. 5.0.0.402 64-bit) to convert over to an .FLV or .F4V file for the web. When I bring these files into the AME, no matter how long the videos are (typically 5-15 minutes long) it is showing the imported video as 3 seconds in length. And when I go to render the .FLV file it renders, but only the 3 seconds.
Just for giggles I thought I would try the same thing in an older version of Adobe Flash CS3 Video Converter -- it had no problem importing the .M4V files and outputting the .FLV files at their full lengths.
Obviously, I would like to be able to use the new AME CS5, but have just been frustrated as all can be.
One additional point, when using Handbrake and using a different setting (Codec MPEG-4) the videos are recognized by AME CS5 at their full lengths, however the video quality is poorer.
Is there an issue with H.264 and AME CS5?
Any help would be greatly appreciated.
DMASH

What specific settings are you using in Handbrake? (Screenshots of the settings dialogs would work well to communicate this.)
Can you post a sample of the H.264 output from AME that we could try?
AME should be able to import the H.264 file. There could be a problem with the file Handbrake is creating, there could be a problem with your installation of AME, there could be a bug in AME, or it could be something else entirely.

Iphoto hangs "Preparing to import" m4v

I have a .mov file which I opened using Quicktime and exported to an "iPad" movie (m4v filename extension -- remember when Apple didn't use extensions and bragged about it? LOL). I then tried to import it into iPhoto. iPhoto hangs with "Preparing to Import" the movie. I have to force quit. What's going on here? You would think iPhoto could handle the output from Quicktime.

I just had the same issue. I am using a macbook pro mid 2010, OS 10.8.5, iLife 11.
It was trying to import photos and videos from my sony nex5n which I found that its SD card is fat32 file format. Therefore, it won't show up sometimes and get stuck when I try to import it.
1- So, first thing to secure my data, I launched Windows on bootcamp, and found the SD, copied all files into desktop just in case.
2- Found this nifty exfat32 from google: https://code.google.com/p/exfat/downloads/detail?name=fuse-exfat-1.0.1.tar.gz&ca n=2&q=
I installed it, restarted and iPhoto didn't stuck anymore. The files showed up. It also showed up on my desktop.
So, with my case it is because of the disk format of my SD card in the camera. I am thinking to reformat my SD to mac format using disk utilty which I will do after I secure my files first. If it didn't work, I will reformat it to fat32 again.
I hope this helps.

Importing only the thumbnails

Hello,
My main photo program is lightroom 2. I have installed aperture 3 in order to test it. I don't want to import all my pictures into the Aperture library. Therefore I clicked in the import menu " Store Files in their current location".So I guess Aperture is only creating links and thumbnails to my pictures. After a while I can see all my pics in aperture. But after closing aperture and reopening it, aperture starts to update the library and starts to copy all pics. The library size increases more and more to over 3 GB after having only 300 pictures updated. Why?
I am looking for a way to use Lightroom and Aperture together but without doubling my pics on the HD. I have over 10.000 pic in dng/raw. It would waste to much space. Can anybody help?
Thanks

Can Aperture Import Expression Media Thumbnails?

I need a cataloging program for my 38,000 images that are currently in Expression Media Pro. Shortly after buying iView I got an upgrade which basically wrecked my catalog. The only help I was able to get was from a discussion group and Expression has a charge of 250.00 for support!! I would buy a new program for that kind of money. My catalog is still somewhat crippled and I am looking for a way out, but the thought of rescanning hundreds of CD's and DVD's gives me a serious headache. Can Aperture import the thumbnails and perhaps the keyworks and some other info? Can any program? I feel like it is only a matter of time when Expression Media stops working without another upgrade and I'm not going there.

It seems that subject is getting little attention here so I took it elsewhere. Take a look as there may be a solution.

Importing .m4v file into FCP

I have a .m4v file that was created by HandBreak. This file was of a live concert. I wanted to edit it into individual songs so I needed to get it into FCP. I looked around and found Wondershare Video Converter Pro. I converted it to a Quicktime. The file size was dramatic. Original file = 4.06GB. The .mov ended up at 550MB. The problem is the .mov quality was pretty bad.
Is there a better way to do this? Can I use a different format that FCP can import? I care more about quality than size, at least while I'm editing in FCP.
Thanks

Did you copy the contents of the VIDEO_TS folder to the computer's hard drive as per the tutorial?
Yes, I did that.
Your internal drive rotates at 7200 RPM whereas a DVD is around 850 RPM. That makes quite a difference. Even a five year old G4 should convert a 1GB .vob in around 20 minutes.
Or are you doing something else that needs lots of CPU resources at the same time?
No, nothing else is going on. I just looked and the VTS011.VOB file is only 1.07GB in size. Any other suggestions? I have it copied to my internal drive. I have an iMac I got new last November. Not that old... I am now at 53% completed. I started the conversion at 10:30 AM, it is now 5:00 PM. That's 6 1/2 hours to convert a 1Gb file. Seems odd...
Thanks
