MOVIE SCORING: 44.1K -- 48K conversion of audio changes placement of...
Recorded mixes and stems for 3 film cues within Logic and then popped the tracks at the head and tail to match up with the timecode burn of picture. I get really really picky about where my pops are placed and both head and tail pop are tight with picture to within 1 bit. GREAT!
These 44.1 files were then xferred to another system running Digital Performer for sample rate conversion to 48K (file transfer to DP via OMF). DP doesn't let you see timecode bits (or maybe the guy who was running the system didn't know how to display them), so I thought it best to verify the sync of the new 48K files back on my system (files xferred back to Logic via OMF).
I aligned the head pops of these file to be exactly on the money with the picture's timecode burn (+/- 1 bit tolerance) and then looked at how the tail pops lined up. Sure enough I found a small problem: the tail pops were positioned 12 bits early! I know that's not much -- just a little more than 1/10th of a frame or so, but still I'd like to understand why there's this discrepancy.
Any thoughts?
X-man,
Maybe you're right, that the math is slightly different, and if so I'd like to understand why.
Amoli,
To clarify, the reason we processed the 44.1 files in DP was to get that all underway while I continued to work in Logic on other things. When I re-imported the newly converted 48K files into my Logic session, of course I changed the sample rate of the session and lined my 2-pop (head pop) up with picture. It was at this time that I noticed that the tail pop was off by a fraction.
There was no pitch change whatsoever. I would have heard that in a millisecond. The only artifact is this slight discrepancy between the positions of the tail pops between my 44.1 session and my 48 session against the same exact picture.

Ridiculously Slow Performance when Movie Scoring - brand new macbook
Hello there guys ! Sorry for my bad english, i will try to do my best.
The title almost says it all. I have a brand new Intel Core Duo Macbook (White, 2ghz, 512 ram, I haven't added any extra ram or anything).
The machine is blazing fast, I am really loving the experience. But when it comes to using a feature I would love to use everyday, it disappointed me. The movie score feature in Garage Band 3. So, I create a very simple movie in iMovie HD 6, capturing video from my fireware camera.
It is a very simple video, no soundtracks, just the original sound that came with the camcorder footage. No stills, reverse, slow-motion, effects or anything. Plain video with sound, just the way it came from the camcorder.
The problem is when creating a movie scoring project with that footage in garageband 3 , the performance is RIDICULOUSLY SLOW. I mean, I press space and the movie strats playing after 1,5 seconds, and the video is halting every other second. It is so laggy that when i press space again to stop the video, the motion continues for another 1,5 seconds until it pauses.
There's absolutely no way to do any work in conditions like that. And the strange thing is that when using garage band to do other stuff, or when working in iMovie with that same movie there's no lag at all. I have even edited 30 minute long videos with effects and soundtracks in iMovie and it was blazing fast, no lag, no halting.
But in Garagaband even the simplest of all videos gets this ultra-slow performance, and it makes me wonder why.
- I have tried desabling recording on the audio track in garageband. I have tried to lock the track. I have done all the steps in the optimizing garage band performance in the help. I don't have firevault activated.
Any help ? Does anyone have a macbook just like mine that is able of doing moving scoring ? Because EVERYTHING ELSE is ultra fast, including video and audio editing, but when movie scoring it *****.
Apple Macbook 13inch 2.0ghz Core Duo 512 60GB White SuperDrive Mac OS X (10.4.7)Ha! It's funny really - you say it all yourself; no extra ram, it doesn't come with enough to run Pro Apps and when you start to use the Scoring feature you are accessing two different functions - playing movies and music tracks - movies are always a stress unless they are very small and the Right Codec - so first up - what format is your movie? Do you have Quicktime Pro? if the answer is No - get it, it's not expensive and it gives your machine many extra abilities - you can then convert your footage to something easy to play.
How many tracks are you working with?
Get more RAM - MacIntel or MacPro needs 4-6 gigs to multi-task happily - with only the base load of RAM it can't.
I have a DP 2 Ghz G5, no where near as fast as yours but I have 4.5 GBs of RAM and a fast graphics card with 512Mbs VRAM - this means Motion and FCP can fly.
We are about to get a MacPro 2.66 Dual with 6 GBs RAM, essential.
Hope this helps. -
I made a movie with iMovie and cannot get the audio when I burn into dvd. I would like to transfer video to a dvd to be played in any computer and TV
Go to the Map mode in your iDVD project and make sure the blue bin at the left is empty. That's where you drag slideshows to if you want the DVD to open immediately to that slideshow and bypass the menu.

If there is an item in there drag it out.

ITunes rented movie not outputting Dolby Digital 5.1 audio
The problem with the downloaded movie (Real Steel HD) is
that the Dolby Digital 5.1 (English) audio is not being putput. The movie is only playing back in
"stereo" mode. When playing back on iTunes there are four audio tracks
to choose from:
1. English 1 (This plays stereo)
2. English 2 (NO SOUND) - I believe this should be the Dolby Digital track
3. French (This plays stereo)
4. Spanish (This plays stereo)
Neither of the two English tracks is outputting Dolby Digital 5.1 audio.
I have confirmed that my PC is capable of up to 7.1 surround sound and
my A/V receiver is capable of even more. I have updated both the ATI
Radeon 4500 driver and the Realtek drivers. I have tested and
confirmed that my PC is capable of outputting sound to all 5 of my
speakers and my subwoofer, HOWEVER when playing back the rented movie
in iTunes the maximum audio is stereo. I have the latest version of
iTunes installed, so that shouldn't be the problem.
I have also purchased another movie advertised as Dolby Digital 5.1
audio (The Bourne Supremecy HD) but I am afraid to begin my 24-hour
viewing period because of these audio problems being unresolved.
My question is: Are there known issues of movies purchased on iTunes
and played back on a Windows 7 PC not playing the Dolby Digital
tracks? If so, is there a fix for this via an iTunes settings change
or a Windows update patch?
From the four audio tracks that I listed above, I believe track 2 is
the Dolby Digital track, yet there is NO SOUND when that track is
selected.
Please help, as this is pretty frustrating when your movie night is ruined for the family especially after you've paid for and waited for the movie to download.I managed to get my DD tracks working.
First had to update itunes to the latest version (10.7.0.21) to get rid of the out of sync sound problem
Then updated the realtek driver. There was an update directly in the realtek website (mine is the HD Audio): http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=14&PFid=24& Level=4&Conn=3&DownTypeID=3&GetDown=false
After all that. I tunes wasn't allowing anymore to select the Doubly Digital 5.1 tracks (an improvement).
Then went to the windows properties for the realtek optical output and checked both options to allow application exclusive access and to have priority (http://dailykermit.wordpress.com/2009/09/11/windows-7-exclusive-device-control/)
After all this, I was able to enjoy my rental -

I have an older Sony digital camcorder, and I am having trouble importing the movie files. Sometimes I get the audio in iTunes without the picture. I have a Pinnacle Dazzle interface. What am I doing wrong. Is there a way to skip the dazzle device?
Chances are the pinnacle is producing .avi files or MPEFG1/2 streams - iTunes may know how to decode the audio but not the video. Download Handbrake and try running the Pinnacle files through it and adding to iTunes - use Universal format unless you have a specific device in mind.
Keep copies of the originals.
Another option might be to try to install Perian. Can't remember if the Apple MPEG2 plugin allows MPEG2 to be played in iTunes.

Movie "stutters" into slices....audio playback is fine
Out of the blue, all my QT movies are cut into vertical slices. Audio plays fine, but picture is in a dozen pieces. Help!
Open the QuickTime Control Panel / Advanced tab and switch the video to "Safe mode".
Quit and relaunch QuickTime and try the file again. -
I move to another country and I want to change my account setting
I move to another country and I want to change my account setting. But when I try, Itunes says that I have an active Itunes Match subscription. How can I deal with this. I don't want to pay again for space in the cloud.
The telephone network doesn't support Face Time regardless of the country.
There are some countries where FaceTime is not allowed because of local laws.
Where are you? If it's anywhere in the Middle East, you're out of luck. -

It is a suggestion on Adobe Dreamweaver:
Could you change the setting of the page or template; to a free platform?
example; move: images, tables and other elements all over the place covering the page. in order to facilitate the user in the design environment.
free
Thank you for your attentionAdobe has been trying this and the product is called Muse ( Web design software | Download free Adobe Muse CC trial ). It doesn't give you the control over the code that most developers prefer but it could help bridge the gap for design if that is what you are looking for.

Anchor points move as I pull them but snap back into place. If I pull them out further, they snap to a new location but not precisely where I want them to. Help?
either snap to grid or align to pixel grid yet again, i guess.

Films - Movies not Working or corrupted in iTunes after changing the album artwork
After trying to change the album artwork for some movies I own, I realized that such movie unplayable after such change and I cannot even revert what I have done. More, it seems like if you press on the "get info" section of the movie, you will notice that the artwork tab is gone and therefore, it’s like the movie is corrupted after changing the artwork. Any ideas? Has anyone encountered this before?
Just checked and I have the updated itunes 8.0.1 with the poster frame problem.
I finally found a fix for the movie album artwork problem.
After realizing several movies had the same poster frame as one of the movies. I deleted the movie with the common poster frame which had been copied to other movies. The other poster frames changed on the other movies because they no longer had a reference to the file from which the poster frame was copied. So I copied the deleted movie back into itunes and then got to thinking that perhaps there is something else in common with the movies which displayed the same poster frame. I found that I had set the album field to the same title. So I changed the album field file by file, to something else. Then I set the poster frame after playing a few seconds of the video at a point where I wanted the frame set to the current frame. I got a film icon on the movie icon for a few seconds while it changed it. Sometimes I had to repeat selecting the different poster frames for each movie because it didn't take the first time... the second time I selected a different poster frame it was then set to the first poster frame that I selected. So now the movies which all had the same album "Aviation" now are all changed to "Flight Training" Of course, now the poster frames for those movies are all the same poster frame but at least they are correct for the type of movie.
So if the album name is set to the same thing on several different movies they will all have the same poster frame. -

there is a youtube video, and i wish to locate the audio and place it on my ipod,can this be done?
Syncing between iPhoto on your iPhone and iPhoto on your Mac is one-way. You can sync selected albums, events, faces, places albums from your Mac to iPhoto on your iPhone using iTunes. This will not delete any albums you created on your iPhone, just add new albums. But albums you create on your iPhone cannot be synced to your Mac.
See this page on how to transfer photos from iPhoto on your iPhone to your Mac:
