Choppy Video from External HD

For the first time, I am storing and editing video on an External HD in iMovie HD. In the past, I have always stored and edited the video directly from my main HD. In playing back the video in iMovie, I notice it is choppy and the picture locks up. I have not previously had this issue. Is this a concern when editing video from an External HD. I am using a Firewire connection. If this is a known issue are there any workarounds such as transferring the video file to the Main HD? If I burn the video to a DVD will I still have the same concern? Thanks for any assistance.

If you save the final product to your internal hard drive, you will not have the jerky video. Same with a making a DVD from the footage. The jerkiness is obviously coming because video needed is coming through a bottleneck somewhere. Is the drive HFS?
After I install NTFS-3g so I could write to NTFS, it seemed like my video playback performance did the same thing you're describing. After installing Leopard, I decided not to install NTFS-3g, and I am using an HFS external drive for my Mac work too without hiccups. Reading from the NTFS drive now is fast enough to playback video from again, too. I just can't write to it anymore.

Play video from external HD to Apple TV

I would like to play videos from an external drive to the Apple TV.
The workarounds I've seen all involve moving the entire iTunes library to the external drive. I want to keep all my music on the internal HD but the videos on the external HD.
Suggestions?

Launch iTunes on your computer
Mac - iTunes > Preferences > Advanced
PC - Edit > Preferences > Advanced
Uncheck 'Copy files to iTunes media folder when adding to library'
This will allow you to drag and drop videos from the external drive to iTunes without copying to the internal drive. Once in iTunes you should be able to watch them on your Apple TV
Hope that helps

How do I Play videos from external hard drive on Apple TV2? Can I just move the iTunes Library to the External Hard Drive?

I have several HD videos stored on an external hard drive and would like to bring them into iTunes and play them via iTunes on my Apple TV2, but I am not sure how to go about it. I don't want to store the movies on my iMac hard drive because it would eat up to much space...so do I just move the iTunes Library to the external hard drive? And, if so...will the Apple TV2 find the iTunes Library on the external hard drive? Thanks for any help anyone can suggest.

iTunes content on an external drive isn't a problem.
The simplest method is to just move your library to an external drive.
If you wanted to keep just movies on an external drive, that's a little more difficult. You'd need to put the movies where you want them to reside on the external drive and add drag and drop them onto iTunes while holding down the option key. Obviously any movies already in iTunes would need moving from their current location and removing from iTunes first.

Choppy video on external monitor

Hello,
Anytime I try to play a video in iTunes on my external monitor, the playback is very choppy. I tried optimizing my computer display settings and driver settings for better playback but that did not resolve the issue. Any suggestions on how to fix this? Thanks for the help!

I have the same problem. I have a WinXP Pro PC with Dual Monitor setup. When I position iTunes on extended desktop and try to play a movie trailer or TV show I get the same choppy effect. But when iTunes is on primary monitor, everything is ok. Thanks for your help.

Retrieving video from external HDD

I have recently made the Jump from PC to Mac for video editing. I quickly discovered that the 200 GB HDD in my computer is not big enough so I used my mac to reformat a 500 GB External HDD to FAT format. After reformatting I transfered about 26 GB of video on to it. Now I can't get it back. When I try to copy it back to the computers hdd the transfer locks up and if I try to force the transfer to quit it makes more problems. Right now I have the drive out of the enclosure in my PC trying to copy the files to it's hdd so that I can try to save them. Any suggestions would be greatly appreciated. Thanks in advance to any of you Mac Pros.

How to stream video from external storage disc using Apple TV

I have a large (1-1/2 TB) library of movies stored on an external hard disc. How do I play these videos on my Apple TV. There is not enough memory on my iMac to move all the movies into iTunes. How can I move my iTunes library (music & video) to the external hard disc?

Hi @Elkayj. In order to play your videos and/or music on your Apple TV, you will need to turn On Home Sharing in iTunes. This will allow you to access your iTunes library on Apple TV, turn on Home Sharing in iTunes on your computer using your iTumes Apple ID.
As for moving your iTunes library to an external drive, you will no to go to iTunes Preferences and select Advanced. There you will see ITunes Media folder location. Click the Change button and select the external drive and directory where you wish to keep your media files. I would suggest you also check "Keep iTunes Media folder organized" and "Copy files to iTunes folder when adding to library".
For more detailed instructions, the following two links may be very helpful to you:

I downloaded some videos to Premier Elements 13 from external hard drive but now the external hard drive is damaged. I tried to open the videos on the organizer which it shows the video but with a yellow ? and says missing file. Is there anyway I can open

I downloaded some videos to Premier Elements 13 from an external hard drive but now the external hard drive is damaged. While setting up my new MAC the external hard drive was dropped and I have been told by an outside source they could not retrieve the files. It had 4 years of photos and videos on it. I remembered that I had downloaded some of the videos from the external hard drive (before it was broke) to Adobe Organizer 13 when I installed the Adobe 13 on my MACOS X 10.9.5. I tried to open the videos on the organizer which it shows the video but with a yellow ? and says missing file. Is there anyway I can open these videos?
Any input is greatly appreciated!! I am sick over losing the videos and had a little hope on Adobe Organizer until I was unable to open them. I am thinking it is due to my external hard drive not being plugged in. I thought when I transferred from the external hard drive to Adobe 13 that it would be there without the external hard drive needing to be attached but maybe I did something wrong.
Thanks again for any help!!!!

It had 4 years of photos and videos on it.
To what did your camera record those photos and videos - camera's internal memory, inserted memory card, other?
Any remote chance that the latter may still exist for you to use to download the camera files to your new external hard drive?

I am having trouble keeping the quality of my video when exporting to my external drive. I change the kind to "original" but when I view the video from the external drive once exported, the sound and picture are distorted.

I am having trouble keeping the quality of my video when exporting to my external hard drive. I have tried to export from iphoto with changing kind to "original" but when I open the video from the external drive the quality is effected. I have also tried copying the video to my desktop and then dragging and dropping onto the drive...same problem. Any suggestions? I would like to save everything to my external drive so that I can delete all of iphoto library and then reimport to correct a few things.

The file sizes are identical. In the finder I did a search for all .mov files. Then when they came up, I went through them and named each one so that they would be easier to find. I am a new mac user and am used to windows. I realized later that I should not have done this....with a mac files should be named within iphoto app...not finder....When I went to open the videos in iphoto, it wouldn't allow me. I had to go into finder, copy to desktop and reimport into iphoto. Then the videos worked again. However, I had the problem with the poor video quality when copied to external drive before that. Actually the first problem I had was when I copied to ext drive...videos were copying as an image...so I learned that you have to change "kind" to original before exporting....then that problem was solved...now they are videos, not images but not of a great quality. Skips, sound and images are not in sync...etc...

Moving photos and videos from iPhone, to iPhoto, to external harddrive. Videos come out to be less than 0 seconds. HELP, PLEASE!

Hi guys! This is my first discussion and I'm not exactly sure what kind of details to put, so I'll just be as detailed as possible. I hope I don't confuse anyone. I really REALLY need help!
I've got a 16 GB iPhone 4S and always find myself filling up my phone with photos and videos, so I upload both onto my MacBook Pro 2011. Now that my laptop's getting full... I'm uploading all of those backed up photos and videos onto a 500 GB Seagate external harddrive.
All of my photos open just fine. It's the videos that I'm worried about. All of the videos that I've loaded from last year (2013) are playing well. Anything before 2013 aren't opening properly. I'm opening the video files directly from my external harddrive. It goes:
     1) Opens up QuickTime Player
     2) Shows that it's converting
     3) Shows a frame from the video, but the time says 0:00-0:00.
I had a LOT of videos from before 2013 and would like to retrieve them if possible. They're no longer on my laptop though. All of the video files are 20 KB - 980 KB and has to convert on quicktime player for me to watch them. Some of the video files I've tried out were from 2013 and 24 KB and opened just fine. I've opened both ~20KB - ~900 KB video files before 2013 and they're all 0:00-0:00 time length. Anyone else having this problem? Thanks!

I have the same issue. We've lost all of our older videos including videos of our children and since passed family dog. I have no idea why this has happened. I have backed up religiously, but now even the archived photos are 0 seconds. So frustrated with iPhoto. This is the second time this awful software mysteriously lost pictures or videos. Last time it was the birth pictures of my second daughter. And now this. Horrible horrible product.
Older videos are all now just 0:00:00 in length. We did not alter these at all!!
HELP!!

Copying or moving video from your Event Library to an external hard disk

I have a Network Drive where I'm used to putted all my iMovie08 files.
I'm start using iMovie09 and i'm no longer able to have my *files/library in a network drive*. Did apple remove this functionality? If this is true this is unbelievable because now a days everything goes to network storage. On iTunes i can have my library virtually anywhere. I need to have the same behavior when i'm using iMovie.
Can someone help me?
with my best regards,
Paulo

Copying or moving video from your Event Library to an external hard disk
If you want to save space on your computer’s hard disk, you can move your stored video in your Event Library to a compatible external hard disk connected to your computer with a FireWire or USB 2.0 cable.
You can also copy Events to another hard disk. You might do this, for example, if you want to create a duplicate copy of your video library or an Event on a friend’s hard disk.
NOTE:When using an external hard disk with iMovie, make sure it has been formatted as Mac OS Extended (Journaled).
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

- If i understood correctly, the solution you propose will replace completely my hard disk library with NAS location.
- What i need (because when i'm travelling i dont have my NAS) is to have both. My hard disk library and the ability to copy/move (drag & drop within iMovies09 ) events and projects to my NAS at my description as i use to do on iMovies08.
And yes all my NAS locations appears with and yellow flag on iMovies09.
best regards,
Paulo

Having trouble importing mpeg videos from an external hard drive to iMovie or iPhoto. Keeps saying unrecognizable format. How do I get it to work?????

I have always had a dell computer. But after the 3rd crash, we decided to throw it out and get a mac. We bought this computer a week ago. I was able to save all our family pics and videos from the dell to an external hard drive. So when I got the new Mac set up, I plugged the hard drive in and had no problem importing all our pictures. But when I tried to import our videos, I ran into some problems. We have had 3 different cameras with each having a different video format. All our videos are either avi, mpeg, or mov. All the avi videos imported successfully but the others will not. I tried importing them into imovie and iphoto and neither one will recognize the format. iphoto says unrecognizable format and imovie just completely freezes and I have to force quit. Here is what is funny. I took the hard drive to my local store and when they hooked it up to their computer, they imported beautifully. Why won't it do the same for my brand new computer? Thanks!

How do i convert videos from a macbook to a pc once on an external hard drive?

A buddy gave me some videos from his macbook and i've got a PC. I gave him my external and he put them on there when i moved them from the external to my pc's hard drive and tried to play in itunes it wouldn't let me. It gave me this message and took me to download xvid. I tried xvid but it didn't seem to work. I'm trying to scour the internet trying to find a converter to be able to play them. Why is it when i gave him some videos i have it went right through to his macbook? He was able to open with no problem? Can someone please give me a program that will convert and allow me to ultimately place them on my iPhone please.
No i cannot afford or want to buy a mac at this time. Other than that suggestions are welcome.

Hi geek girl,
The only way you can achieve this is by starting up the MacBook in TD mode, with the relevant disc in the Optical drive. You then have to connect the MacBook to a Tiger capable PPC based Mac, attach the external drive to the PPC based Mac and boot the PPC based Mac holding down the option key to access the Startup Manager. Then choose the OS DVD as the startup disc on the PPC based Mac (much as I mentioned in your thread in the iMac G5 forum)
Of course, if you have a normally operating PPC based mac you can simply use it instead, without the need for the macBook at all! This trick is only useful to re-install an OS if the optical drive in the PPC based mac isn't working, but everything else is for example.
In your case with your imac G5, though, I think you have a more serious issue, and simply getting an external drive with the right PPC OS on it isn't going to help you until it is resolved.
Cheers
Rod

Choppy video playback with airplay from Macbook Pro

I experience very choppy video using airplay towards my Airplay unit (3rd gen).
I am using a Macbook Pro (15" retina, late 2013 version) with these specifications:
- Intel Core i7 2.7 GHz.
- 16 GB ram.
- 768 GB flash/SSD.
...and so on. I have the Mavericks OS installed (10.9.1).
When I duplicate or extend the screen of the computer to my Apple TV it is chopping EXTREMELY much. I am not talking a little bit - but it is not even watchable. I thought that it could be the router itself as the connection is (probably, correct me if I am wrong anyone) is directed from the computer - to the router - and then to the Apple TV, which could make the router like a filter in the process. And if something would prevent the signal from reaching the Apple TV with "full speed" it could prevent the actuall image.
However, when I am using the iPhone 4S and streaming video (both video found in my phone as well as streamed TV from apps such as Magine.com) the image flows completely flawless. There are not even a touch of lagging. It flows perfect, just as watching a movie directly on the TV.
The networking hardware in the phone is slower than in the Macbook Pro retina (late 2013) - both for sending and recieving data. But still... my iPhone works better than the Macbook Pro for the Apple TV. Even though that the processing, memory, graphic and networking power is probably a thousand times faster in the computer... it still performs really bad.
I have followed some discussion threads here (https://discussions.apple.com/message/22051725#22051725 and https://discussions.apple.com/thread/5734226?tstart=0 just as a couple of examples). I have accessed my router (Netgear Gigabit EVG 2000) and increased the Wireless mode to "up to 270 Mbps. I have also followed the previously linked threads and disabled the WMM (in the QoS-section). I felt that this made a little bit of a difference...
...when I am mirroring the screen and scale down the resolution to match the AirPlay screen (full-HD, 1920 x 1080) it works okay, but still chops quite a bit almost all the time. But if I extend the screen and want to watch TV at the same time as I am doing something else on the computer - then it chops so that it is not even possible to watch.
This have to be something either with the Mavericks OS or with my network settings - can anyone help me...? It would mean A LOT!

Curious why you think it would be my network when the same network is being used by the iPad 3rd Gen and iPhone 5 and they both stream without issue. As far as the other items you mentioned, all devices are up-to-date with the latest firmware/software and the latest MacBooks do not have ethernet ports. Speedtests that I have conducted also indicate that bandwidth is not the issue as the results show that the speeds received from the router are quite impressive.
