Audio & Video fade
How do i fade the audio and video in, and then at the end of the entire clip fade the audio and video out??
And a prolonged one, not a cheap 1 second fade

After exporting to Encore, no audio/video transitions
I used keyframes to create audio/video fade-ins and fade-outs between chapters. It looked perfect in Premiere. I then went to File > Export to Encore. Let it render for 3 hours. Then the resulting m2v/wav combination in Encore doesn't show any evidence of the audio transitions that I had created. This happened for 4 different 2-hour videos I am trying to make. What am I doing wrong?
If you set the work area bar to span one of the problem transitions and then export that work area to a DV AVI file, when you play the exported file in an external media player do you hear the audio transition?
Cheers

I'm trying to make the video fade out while the music continues to the end. I also want to fade in with the video while the music is playing.
Of course they do. At least in Expert view. Have you toggled open the tracks so that they're not in collapsed view?

Playing movies: Video fades to black for a second every 5 minutes
I have a problem with front-row: with some avi movies, video fades to black and back every ~5 minutes; audio is played normally without any interruption. I have perian 1.1 installed and the movie has no subtitle. 5 minutes is exactly the display sleep time: is that a coincidence or something is wrong with front-row disabling sleep timer ?
thanks
cheersI have this same exact problem. I have a newer Intel Mac Mini 2.2gh with dvi/hdmi out to external hdtv. At exactly 5 minutes on some .avi or .mkv movies, I love video but still get audio. I always thought it was just me except that it drove me so crazy today that I decided to look for a solution.
The video files themselves play fine in quicktime and/or VLC. It just ***** that Front Row stops playing them. It even happens when I fast forward.
As a side or possibly related note, has anyone else experienced stuttering in Front Row on large files? More importantly, does someone have a solution to the missing video in Front Row. -
Newbie with FCE so thanks in advance. I am trying to add an audio Cross Fade. Following Apple Pro Training book: Placed play head before edit point. Clicked on edit point on a1 track and point becomes highlighted on both audio tracks (and video track). Then chose Cross Fade (tried both). Problems: the Cross Fade icon does not appear on tracks. I also tried to drag and drop but if I do that the highlight disappears with no cross fade icon appearing. FYI when marking the highlight point the vid track also highlights unlike the photo in instruction book. Both audio tracks are unlocked as is vid track. I am on a MacBook Pro and have already done some experimental vids that have worked but have not worked with transitions yet.
Thanks again.
PS Hoping I won't have same problem with vid transitionsOpen the clips into the viewer and check to see if you have handles to create the overlap for the transition.

Quicktime Pro - Simple video fades?
With QTPro can I do simple video fade in/out to and from black?
I just need to tidy up the ends of a movie file
Is this possible in QTPro, to the nearest frame for precision editing?The MPEG Streamclip software as recommended by QuickTimeKirk solved a similar problem I was having with running video and audio. I had bought QuicktimePro and Quicktime MPEG playback, only to find that audio from my MPEG 2 camcorder content did not play on my MacBook. Several calls to Apple tech support and long waits in queue did not help get me the help I needed. After searching the online Apple support resources, I found the answer - Eureka! Audio now plays loud and clear. Thanks QuickTimeKirk for the advice. User/discussion forums are the way to go - corporate tech support is more often than not a joke and waste of time.

How can I display & split the audio & video from the same digitized clip?
I digitized a scene into iMovie that I edited on a professional system which I don't have access to anymore. The whole scene is 1 clip. Now I see a few tweaks that I want to make, so I was hoping to do them in iMovie.
I want to "pull up" the audio in one section - meaning I want to take cut about 20 frames of audio from the end of a shot, and then move all the other audio up to fill the hole. To compensate for the missing 20 frames, I'll cut video off the head of the next shot. Some call this prelapping. Some call it an L-cut. Some call it asymmetrical trimming. Either way, I can't figure out how to do it in iMovie.
My clip appears in the timeline as one track - a single track that contains the video and 2 audio tracks. How can I display the audio that's tied to the video on its own track? Then I think I could split audio & video wherever I wanted and trim things up - but I can't figure out how to do it.
Am I asking too much of this software?
BTW, I never see the option to "Split audio clip at playhead". I'm not displaying clip volume or waveforms. Choosing to display waveforms doesn't show me anything. Maybe iMovie thinks I'd only want to see waveforms of audio that isn't tied to my video-and-audio clips?
Thanks in advance for any help...Jordon,
"Am I asking too much of this software?"
No, you're not.
You first want to select your clip(s) and choose Advanced>Extract Audio.
This will copy the audio from the video clip and place it on one of the two separate audio tracks while lowering the audio level to zero in the original video track.
You can now edit and move the audio independently of the video.
With the audio clip selected, you'll find you now have access to Edit>Split Selected Audio Clip at Playhead.

IDVD 08 audio/video sync drift toward end of DVD movie - fix/workaround?
Anyone know how I can fix this issue? It's driving me crazy.
I've just spent a few evenings in iMovie 08, editing together the video of my son's birth. All looked & amazingly good in iMovie. The "Large" .m4v file output by iMovie - Shared with the Media Browser - plays perfectly in Quicktime too.
However, after adding that shared movie to iDVD 08, and burning a DVD, I noticed that the audio sync drifts toward the end of the Movie when plated back. At the start of the DVD all seems well, but by the end of the ~1hr 20 minute movie the audio is unbearably out of sync with the video. Completely unwatchable.
After a little Googling I came across some reports that iDVD might not deal well with video that's been recorded with 12-bit audio. I've confirmed that my camcorder is (was!) set to 12-bit rather than 16-bit (the default, I'm sure). So if that's the problem I'm hosed... it's not like I can get a retake on that footage
Is there a reasonable workaround for this issue? I'm obviously unable to re-take the video (or the other 10 hours of DV video tape I've yet to use in an iMovie project). Ideally I'd like Apple to release a patch for this. Shouldn't it be possible for iDVD to account for audio that was originally recorded in 12-bit... even if it's just a checkbox you have to select to tip it off?
Then again, perhaps this is totally unrelated to the 12-bit issue, and this is just a run of the mill bug?
As I said... iMovie generates a MPEG4 video file of the Movie that looks/sounds perfect, so it seems this sync issue's being created somewhere in iDVD as it's rendering the audio/video to burn to the DVD...
Thanks in advance.I've tried most of the options I can think of, and the audio sync drift issue continues on this ~1hr 12 minute iMovie/iDVD 08 project.
A couple of promising ideas tried used QT Pro, to export the audio track from the iMovie generated MPEG-4 file - as a WAV file, resampling to 48kHz and 16-bit... then Adding this back to the video track in the MPEG-4 file (having deleted the original audio track). In another test I also tried the Add to Selection and Scale option. Oddly enough I think the Add to Selection and Scale attempt generated more sync issues than before in the final DVD movie... so I stuck with the MPEG-4 file containing the video track and the added, resampled at 48kHz & 16 bit, WAV audio track.
This was saved as a self contained Movie file, producing a QT .mov file. I moved this .mov file into the iDVD projects directory structure so that it was avalable in iDVD's Media Browser. I then reworked the iDVD project to use this QT large.mov file, instead of the original iMovie large.m4v file.
As a reminder... the original large.m4v file has the following properties:
29.97 FPS H.264 Decoder, 960 x 540, Millions
AAC, Stereo (L R), 44.100 kHz
0:01:12:07.16 duration
The resampled and saved QT MOV file has the following properties:
29.97 FPS H.264 Decoder, 960 x 540, Millions
16-bit Integer (Little Endian), Stereo, 48.000 kHz
0:01:12:07.16 duration
BOTH versions of this Movie file play flawlessly within QT Pro... there's no audio sync drift evident toward the end of the movie unless I use iDVD 08 to burn either movie file to a Physical DVD (or DVD Disk Image). In both cases the resultant DVD Movie exhibits significant audio sync drift as the ~1hr 12 minute movie progresses. The sync goes out by ~ <= 1 second based on a rough visual assessment.
I've not yet tried to burn either the original iMovie produced MPEG-4 video file or my QT Pro tweaked audio track .MOV file version to a DVD on my PC...
... But I have used an application called Burn (referenced in this earlier/archived iDVD sync drift forum post: http://discussions.apple.com/thread.jspa?threadID=1332100 by user F Shippey - http://burn-osx.sourceforge.net/) to take the QT Pro tweaked .mov file version of the original MPEG-4 file and burn it to a DVD...
Results:
The Burn app burnt DVD plays with NO audio sync issues!... Even though it was generated from the same audio tweaked (48kHz/16-bit resampled) QT Pro .mov file.
However, whenever I burn a DVD using iDVD 08 the audio sync gradually drifts. It matters not whether I use the original iMovie 08 generated MPEG-4 movie file, or the QT Pro version of that file with the resampled audio track (the same one that works fine with Burn).
It sure looks to me like iDVD has a problem... Again, refer to http://discussions.apple.com/thread.jspa?threadID=1332100 for someone else who seems to have run into similar challenges.
Am I overlooking something?
Thanks in advance. -
How do I connect an iPhone 5S or 6 with audio video cables?

Audio / video sync issue in playback
for every recording i've made, when i play back the archive there is noticable lack of sync between the audio and the person's mouth. the video seems to lag behind by almost a second. the good news at least is that the delta is constant.
has anyone else experienced this? it's happening in any scendario i try, even if i'm just recording myself.
is the LCCS dev team aware of this? since audio and video streams are recorded separately, is there any way for me to programatically 'nudge' the streams into sync?
it's currently a show stopper, it looks really bad when the sync is so obviously absent.finally getting back to this..
i did as you suggested and recorded a video of myself using the recording and playback examples provided with the SDK (the 2.2 newest version btw).
the de-syncing of audio and video is definitely there. it seems especially bad for longer recordings. however, an interesting thing i discovered in playback:
- sometimes, if i drag the playhead somewhere in the recording, pause, and then hit play, video and audio fall into sync.
- if i start playback from the beginning of the recording, audio/video is always out of sync.
i understand that the video and audio streams are recorded separately and thus played back separately. my guess is that when those streams are retrieved and playback begins, one starts before/after the other because they're not retrieved at exactly the same time. it seems some extra work is required to ensure that their playback commences at exactly the same timestamp within each stream.
i can provide my recordings as an example if required.
this is a total showstopper for me. it renders the entire recording service useless if the playback can't have sync between audio and video. i would be happy to help with testing this more. can someone from the LCCS team comment on this issue?
thanks

I am using Parabola (a fork of archlinux), Icecat 31.4 and ALSA
Icecat and firefox seem to hold onto the soundcard when I click on a new html5 audio/video link in the same tab. The next video/audio element loses sound. If I wait 10 seconds and click back to the start of the audio/video, the audio returns. I often get cpu spikes for icecat when it happens.
I have tried this with both motherboard and usb sound and I get the same problem. I have disabled extensions (addons) in Icecat, deleted profiles, reinstalled the browser and even installed firefox from the AUR and it still occurs.
I have disable gstreamer in about:config and restarted and it still occurs.
My .asoundrc is this:
pcm.!default {
type plug
slave.pcm "hw:0,0"
All my other audio applications work. I have noticed that if I use pulseaudio it fixes it, but it should work without anyway, like it used to. I think something happened after an update, but I'm not sure.
Any help would be appreciated. I know it's not a big problem, but it's really frustrating and I've had it for ages. I even switched browsers to get away from it.*nerding out*
I am not an expert in this and if we get stuck I have found a mailing list for the alsa project that can be contacted: http://www.alsa-project.org/main/index.php/Mailing-lists
Gstreamer is disabled in Firefox as well as the os?
Since you are seeing issues with ogg files and moving video/audio combination I started to dig into file formats {sox http://sox.sourceforge.net/soxformat.html}

Help! I just moved my itunes library from a Win 7 computer to a new Win 8.1 computer following the instructions on the itunes website. Everything is good except I'm getting an error message on the Win 8 computer if I try to play a CD or get an audio file off of the internet. I get an error message that says "iTunes has detected a problem with your audio configuration. Audio/Video playback may not operate properly. I don't know where to look for or fix the audio configuration on the win 8 computer. As far as I can tell the iTunes configuration looks the same as on the other computers in the house. At this point I don't dare plug my ipod touch into the Win 8 computer for fear it will get messed up.
I have the same problem and I know that it is due to my PCI Audio driver not being compatible with WIndows 8.1.
iTunes isn't the only program that can't direct sound to the built-in speakers anymore. The obvious solution would be to update the drivers, but unfortunately Dell does not provide an updated driver for my model, so I am stuck with that.
However, saying that, only my laptop speakers are affected by this. I can use sound fine on applications where I can choose the output device and direct sound to the head phones, but for some reason iTunes does not let you choose the audio device manually.
To listen to music I imported the iTunes Library in Windows Media Player and changed the audio output using the following instructions: http://windows.microsoft.com/en-us/windows7/c00d11ba
However, I would also like to rent movie's from iTunes,
Would be great if iTunes would let you choose the output device, too, like most other applications using sound from Skype to Windows Media Player,... -
'Source play' and 'audio-video sync' problems with PE8 on fast WIN7 64 bit computer
I am transferring Hi8 videos, about 2 hours long, to my WIN7 64 bit computer with PE8. [Dell Mobile Precision M4400 Computer Workstation (Intel Core 2 Duo T9900 500GB/4GB); NVIDIA Quadro FX 770M, 512MB] I seem to have several problems:
First, after importing the file (.avi), I get a message about ‘dropped frames.’
Secondly, when I try to play the video in the source monitor, the audio plays but the video doesn’t; it only shows the first frame [this is after waiting until the video is ?recognized? ] I can use the shift-arrow key and see that the video is there.
Thirdly, I can play the .avi file in other players, e.g., avidemux or PE pro CS5 on another computer. There, I see that the audio and video are not in sync; the audio can be up to 300 ms ahead of the video (as determined using avidemux).
Questions:
1. Why doesn’t the source monitor play the video? Is this a problem with PE8 (latest update as of 3 March 2011) on aWIN7 64 bit computer (intel duo core. 3 GHz).
2. Is the audio-video sync problem the result of the ‘dropped frames?’ How can PE8 correct this? Avoid this? Or, is it coincidence?"I think you're telling me you're using a backwards compatible Digital8 camcorder to capture your video as DV-AVIs. Is that right?" YES
"Are you using Premiere Elements to do this capturing?" YES, AS ABOVE PE8
"Go to the File menu and select Properties. It should show a standard DV codec being used for your video and audio."
WMP v12 is dumb. Under properties, media, it says 'video.' However, avidemux gave me the information state above: video -- Codec 4CC: dvsd, frame rate: 29.971 fps; audio -- codec: PCM, channels: Stereo, frequency: 48 kHz.
So, back to the Questions:
1. Why doesn’t the source monitor play the video? Is this a problem with PE8 (latest update as of 3 March 2011) on aWIN7 64 bit computer (intel duo core. 3 GHz).
2. Is the audio-video sync problem the result of the ‘dropped frames?’ How can PE8 correct this? Avoid this? Or, is it coincidence? -
How to use rtp to transmit data other than audio / video
hi all,
as you all know the jmf is based upon a specific paradigm:
data source -> player (processor) -> renderer.
i am not being very precise on this but that does not matter.
i want (for testing purposes) to create a tool that transmit some custom data
(maybe even nonsense) over the rtp packages.
so as you may now see this would not work quite right with the mentioned
paradigm since there would be no audio/video to play-process-render.
so how would i go about to utilise the rtp abilities of the jmf without adhering
to the whole player-whatever shebang.
what i have figured out is that there is a way to transmit custom rtp-payload.
there is even an example on the jmf solutions page but even this one uses
an audio format (pcm).
i hope what it is clear to the dear reader what i want to do and maybe some-
one can help me with this.
p.s. i am not one who wants to get the whole source code (like so many
others do on this forum) for a project someone may have done on this, what
i need is a hint in the right direction.
thanks for your attention and thanks in advance for any useful hints.Hi, I would like to make some comments that may help
you to find out how to manage your problem.
If you have a look to the JMF 2.0 API, Guide,
"Understanding the JMF RTP API", Figure 8-2
http://java.sun.com/products/java-media/jmf/2.1.1/guide/RTPArchitecture.html#105171
you can notice that the processor is not essential.
In this pciture, the processor is inserted between two datasources,
to let you perform some operations on the media that is read from
a file or a capture device.
But the SessionManager just needs a DataSource.
With what you say, I can imagine that you want to transmit
real-time data that is not related to standard media formats.
In principle, the only think you must do is to extend the
javax.media.protocol.DataSource abstract class and implement
it at your own convenience.
Once your custom class is written, you can call the SessionManager's
method createSendStream(DataSource ds, int streamindex) passing
for argument an instance of your mentioned custom implementation.
Hope this helps.
Good Luck ;-) !
