Wow, thanks for multithreading video-pipeline
Hi,
we installed today the fp 11,...19 Beta on our OSX Test machine. The machine itselfs has a ATI PCI card.
In the past we are fighting to decode an mpegTransport Apple HLS format thru our own MediaPlayback Plugin and OSMF. We implement a lot of hacks to decode the m3u8 playlist that includes the mpegTS segments.
In the decode frames we saw a lot of "jitter-refresh-rate", specially in fast moving scenes..
The problem has gone with this beta-version. Also the seeking in HTTP Stream with adaptive bandwidth works very fast and better now.
I dont know who from developer adobe guys has include this, but when i would meet iam i would spend the team a box of six-pack german beer.
If you want to try it out you can please a demo stream here:
http://onlinelib.de/Streaming_Solutions.html
With this solution we have now one videoformat that can be played on any devices and on any webserver!!!!
I have to test now windows.
Gary
Hello,

Hello Folks, just wanted to share a little tip we came up with. Not sure if it's new or not, trawled the forums could find nothing so I'll post it and if you already know then no harm done.
We were looking for a video pipeline solution for a multi screen installation in a new facility.
Basically several plasma screens hooked up to a Mac each via DVI so the Macs act as a playback device for an in house TV program. No presenters just video packages of varying length and type.
Instead of making up the packages and then firing them off in one time line we wanted a pipeline to load up QT movies one after the other seamlessly so alterations could be made quickly and we didn't want to spend any money. Also, some packages are pure motion graphics and they look much better in H264 or DVCPro50 whereas the video material is all DV-PAL.
Automator was no good because even though it could play the QT's one after the other in presentation mode the scaling and closing after each movie was no good in terms of presentation.
So we had to look elsewhere and what did we find?
iTunes6
Thanks to Apple implementing video playback options into the 5th Gen iPod and therefore doing the same with iTunes you can create a video playlist that will run video packages full screen on a loop in any order you like all at the touch of a button.
We have tested it with H264, DVCPRO50, DV, etc, etc and it works like a charm. Just make sure the packages are top and tailed because there is a slight pause when a new video is triggered by the playlist so you need black frames to hide it.
All we need now is an Automator script to run iTunes in full screen video mode and we have the best, free, video pipeline solution money never had to buy!
Like I say, if you already know this then excuse my nonsense, just thought we would share it, and if you did know, why didn't you tell anyone?
;oP
NB: Better to switch off iTunes management feature so it doesn't make copies of the video files in the iTunes folder. Otherwise you will be duplicating all those huge video files!Update:
Ok we have done some more testing and it seems iTunes didn't like it when the video files were not in the iTunes music folder, the playlist would jump out of full screen when this was the case. It may have been a random glitch but trashing the prefs and switching on iTunes "copy files" in prefs fixed the issue.
Sadly, sharing Movie based playlists doesn't work across the network, probably to protect the video downloads for copyright reasons (we don't have any purchased video downloads as yet to test the theory).
We are quite happy to use iTunes in this way for mission critical video delivery, it appears stable (ran a 6 video playlist with multiple codecs on a loop for a couple of hours with no problems).
I'll check back if we find anymore quirks using iTunes in this way!
cheers

Multithreaded Video Decoding and Seek frame accuracy for seamless m4a loop
Hi everybody,
We read that flash 11.2 and Air 3.2 will improve the seek functionality.
Right now being able to select a part of a track and precisely loop it is very difficult and complex for an mp3 but impossible with an m4a due to NetStream.
So if you could let us know if the Multithreaded Video Decoding and Seek frame accuracy improvement in 11.2 and 3.2 will bring us a solution would be great!
Basically as m4a are local files does 11.2 and 3.2 will allow to seek not only to keyframes but anyframe? This is key functionality to all music applications. If not do you think it will come soon?
Thank YouSeamless looping using seek will not work very well. It will have to be a separate feature.
You could submit it as a feature request. -
Thanks for responding. Since I upgraded ITUNES to IOS 6, my IPOD Touch no longer works at all. I had numerous apps, music and videos on this touch. It made me restore to factory reset and it still does not work!!! Nothing I do will work on this touch now. I have so much data on this, I don't want to loose or have to restore!
Can you help me?
ThanksIf you restored to factory settings/new iPod and still have the problem that indicates a hardware problem.
Make an appointment at the Genius Bar of an Apple store..

Does anyone know why video image in events section has a certain dimension and instead when I import same video in a clip, the size of video image is minor? Thanks for help
This may depend on your chosen encoding options for the Mails (MIME vs. Base64 or similar) and/or the mails being reduced in size and sliced up server side. Apple (and Google) do stuff like recompressing images when viewing mails on mobile devices from an Apple ID or Gmail account... You have to turn it off in their web frontends....

I am not able to download mp4 files (video and audio) to iTunes since I updated to iTunes 11. Thanks for your help.
Thank you for clarifying. Your question is in your browser, not in iTunes. Each download link is different, and it has nothing to do with the File menu. You can save media files by secondary-clicking on the link to the media file and selecting Save File to "[your downloads folder".

When I make a video with my iPad, is it automatically sent to the Cloud? Thanks for your help!

No, it's not automatically sent to iCloud.

How do I clean my mid 2007 iMac?
The disk space is running VERY low and I would love an idea. I make videos and upload them to youtube and I need space to do that. Thanks for your time!
If you have an idea please respond!You should never, EVER let a conputer hard drive get completely full, EVER!
With Macs and OS X, you shouldn't let the hard drive get below 15 GBs or less of free data space.
If it does, it's time for some hard drive housecleaning.
Follow some of my tips for cleaning out, deleting and archiving data from your Mac's internal hard drive.
Have you emptied your iMac's Trash icon in the Dock?
If you use iPhoto, iPhoto has its own trash that needs to be emptied, also.
If you store images in other locations other than iPhoto, then you will have to weed through these to determine what to archive and what to delete.
If you use Apple Mail app, Apple Mail also has its own trash area that needs to be emptied, too!
Look though other Apple Mail folders like the junk mail and delete the mail that is in there. Look through your sent items folders and see there is any mail in there that can be deieted.
Delete any old or no longer needed emails and/or archive to disc, flash drives or external hard drive, older emails you want to save.
Other things you can do to gain space.
Once you have around 15 GBs regained, do a search, download and install OmniDisk Sweeper.
This app will help you locate files that you can move/archive and/or delete from your system.
STAY AWAY FROM DELETING ANY FILES FROM OS X SYSTEM FOLDER!
Look through your Documents folder and delete any type of old useless type files like "Read Me" type files.
Again, archive to disc, flash drives, ext. hard drives or delete any old documents you no longer use or immediately need.
Look in your Applications folder, if you have applications you haven't used in a long time, if the app doesn't have a dedicated uninstaller, then you can simply drag it into the OS X Trash icon. IF the application has an uninstaller app, then use it to completely delete the app from your Mac.
Download an app called OnyX for your version of OS X.
When you install and launch it, let it do its initial automatic tests, then go to the cleaning and maintenance tabs and run the maintenance tabs that let OnyX clean out all web browser cache files, web browser histories, system cache files, delete old error log files.
Typically, iTunes and iPhoto libraries are the biggest users of HD space.
move these files/data off of your internal drive to the external hard drive and deleted off of the internal hard drive.
If you have any other large folders of personal data or projects, these should be archived or moved, also, to the optical discs, flash drives or external hard drive and then either archived to disc and/or deleted off your internal hard drive.
Good Luck! -
I bought a new Panasonic camcorder to edit in iMovie 10.0.3. I need to choose between the AVCHD choices and the ALL MP4/iframe choices. I don't have a clue as to which to use. I just want to burn video to DVD to have and share. Thanks for any help.
It sounds like you have assigned the primary click on the trackpad to something else, perhaps a gesture.
Use your mouse, login and then open the Trackpad preference pane and see how you have the interface configured.
Oh and you can have both the Magic Mouse and Magic Trackpad powered up and working at the same time. No need to keep moving batteries around.

What is the best value iMac config for hd video editing.? I was going to go for i5 3.1 ghz with 4mb ram, but should I go further? Thanks!
You have it currently installed? Can you go to the System Profiler and click on Applications (will take a while to populate) - take a look at your FCP and check what it says on the right - Universal, Intel, or PPC? It'll look like this:
If it's Universal or Intel, it'll run in Lion. However, the installer may or may not be PPC - that you may not know until you try to install. If you have it currently installed, then you could do what I did - move over all the files manually. I have a list of files for FCE and would assume they'd be the same with FCP: copy them from the old Mac and insert them in the very same spots on the new one.
Here is the list for FCE:

I purchased an adapter for playing videos from my ipod touch on my tv. It works fine for videos I have purchased but won't allow me to watch videos from Hulu Plus. What should I do to remedy the situation? Thanks!
The iPod TV out only works for aps that support TV out. The description of Hulu Plus only states that iiPad supports HDMI video out (SD only)

What is the best Computer for HD video editing where can I get it under $3000-5000? Thank you!
What is the best Computer for HD video editing where can I get it under $3000- $5000.00?
The wording of your question suggests you may be new to video editing, in which case the types of projects you will be doing may not be the most complex.
Please accept my apology if that assumption is incorrect.
The cheapest computer available will edit 1080p video perfectly well but if you must have the "best" you will be looking at nothing less than a MacPro.

Hello All...
Back after a brief absence, things look a little bit different.
I'm trying to take a 16 minute mini dv video and compress it for use on the web. I'm interested in any suggestions you may have on settings for the video and audio tracks. I've tried using Sorenson 3 (15 frames, key frames set to automatic, 320 x 240) for video and IMA 4:1 (mono) for audio. The resulting video looked great but the file size came in at about 255 Mb.
Thanks!

Message was edited by: Dan FoleyThank you for the replies. Everyone was correct about the jack, interface, and phasing problems. I have been unplugging my motu audio interface and then using headphones at work. I have not changed any detailed audio output settings in logic. When I read that the jack might be a problem I tried switching headphones. This actually helped. I am using dre-beats headphones and they seem to be having issues with the mac/jack-(the phasing/panning problems. I can use these headphones with other devices but not the mac. I have to use ipod ear buds and the phasing seems fixed. Hopefully this information is helpful to someone else.
If anyone knows how to correct this issue please let me know its difficult to know what my final mixes are going to sound like and I have had to keep bouncing everything into i-tunes- sync to ipod and then listen in my car radio.
