Adding transitions creates audio noise

Adding transitions creates a slight "pop" noise at the beginning and end of the transitions. Any solutions for avoiding or correcting this problem?

You might want to try using something like a Fade Out or Fade In instead of one of the transitions that add or subtract to the length of the video
[Quoted from iMovie Help]
Some transitions (for example, Cross Dissolve and Push) shorten your movie by a few seconds, depending on the speed of the transition. For example, if you add a transition with a speed of 2 seconds, iMovie overlaps 2 seconds from the first clip and 2 seconds from the second clip as it renders the transition. This shortens your movie by a total of 2 seconds.
The Overlap transition freezes the last frame of the clip on its left and superimposes it over the next clip. Fade In/Fade Out blackens the last frames of the clip on the left and the first frames of the following clip.
[End quote]
I think the best way is to extract the audio right after you import and before any transitions are added.

Replace video with a still - transitions create audio sync issue

Trying to insert stills in a video and have the audio continue over. Have been successful up to adding transitions between the still and the existing video. When I add a cross-dissolve on both sides of the still - the audio becomes out of sync with the video on the back end. I've been able to add the transition to the front side of the still without corrupting the audio and video sync - only when I add to the end of it do I get the problem. Help me... Thanks.

You're welcome.
I'm glad I could help.

GPS creates audio noise

When GPS signal is turned on it creates a signal noise on the audio feed. When turned off in the menu the noise is gone instantly. I'm using the SONY UWP-D16 Digital Wireless system via the hotshoe mount. Does anyone have this issue?

I have not experienced the problem myself, so I will let someone else answer the question who has seen it. Personally I have never had a problem with audio on the FS7, but I think it is a known issue that the GPS can interfere with Sony's wirelss reciever when it is attached to the MI-shoe. The solution is just to turn off GPS. Is anyone really using it anyway?

Girder Plugin and audio noise

I ave a problem with girder and the msi remote plugin.
There is a ticking noise like every 100ms or something that drives me crazy.
I use headphones and it's very noticable.
If i enter girder setup, uncheck the msi remote plugin, click ok.
The noise is gone.
I have no idea why a remote plugin can cause audio noise lol
Is it just my system or is this a known problem ?
I have tried the nforce drivers which came with the box, and yesterday
also the latest nforce drivers, same problem.
Strange thing is if i use the MSI mega key finder it doesnt have that noise...
Dst

Hi
The plugin uses the same API as the Radio does. So it seems to be not unlikely that the driver will create noise on your audio output.
You're saying that you hear the noise every 100 ms. Please try to adjust the time resultion in the plugin's settings (let's say for 1000 ms). If you hear the noise then every second, the problem is related to the MSIDrvIF.dll driver which comes form MSI. In that case there is nothing I can do about it.
Otherwise the problem is somewhere else. Perhaps the driver initialization process behaves strange on your system. Then get in contact with me and I'll try to adjust the source code (adding mute to the radio or something like that).

Pictures "snap" after adding transitions

I'm very frustrated with IDVD. In every movie I make there are a few pictures that, after adding the transition they "flash", it happens usually at the begining of the movie, but not necessarily. It is a random flaw and it comes with a sound that is similar to the sound we hear when the monitor goes to sleep.
I've tried deleting, clearing the transition and the picture, but whatever stays in its place acquires the same defect. I don't know what else to do, I've tried everything. If someone knows what I should do, please write back, I have loads of clips to make, but I won't until I know how to fix this.
I've read similar complaints but with video after adding transitions, but mine only happens with pictures.
thank you,
Paula

Hello, Paula,
I noticed that you posted to the iDVD discussions, but your problem sounds as if it occurs with your iMovie, not iDVD.
Having a 'flash' with certain transitions has been noted in iMovie postings before. I have had that happen on occasion. The solution for many of us has been to delete the offending transition, and then play the end of the clip preceding the removed transition. You have to play it frame-by-frame, and you may see one frame of all white. Delete this one frame, redo the transition and you should be ok.
If the video is ok, but there is still a pop/snap/buzz noise, that is also a known problem and has occurred since iMovie 4. This 'popping' noise usually occurs between a silent photo and a video clip.There is no good solution yet, but if you zoom out the timeline until you see the cross-shape of the transition, you can select 'Show volume levels' and manually adjust the volume of the transition. Sometimes I have just lowered and then raised back the volume level bar and the noise has markedly reduced.
Hope this is helpful to you!

Working with AVI: Adding transitions

I have a dozen AVIs from my Canon camera that I would like to edit together in FCE. I can import and view them fine on the timeline. But the program will not allow me to add transitions in between the individual clips. However, I can add transitions within the same clip. It just does not work when I want to put transitions between separate clips.
I have tried converting these clips to DV, MPEGS, QUICKTIMES before importing and it does not resolve the problem.
Any suggestions?
M

To add transitions between clips they must have "handles", that is, additional hidden media after the first clip end point and before the second clip start point. To do that you must move the IN and OUT points of each clip before adding transitions.
I suggest you to convert your clips to .mov (with DV-PAL or DV-NTSC codec, and audio stereo uncompressed PCM 48 kHz) before importing to FCE. You can use MPEG Streamclip (free) to do that. This doesn't add handles... but it avoids preliminary FCE rendering.

Loud Audio Noise while Capturing in PP 5.5

I am using a Formac Firewire Audio & Video external capture device with a Firewire 400 to 800 cable to my 12 Core Mac Pro 2.9 GHZ.
Does anyone else use this device?
I am getting a strong audio noise thru the firewire port regardless if my audio input in the "Line In" or "Digital In" in the system.
The noise does not occur in any other application that records video which uses the system audio line in.
I guess my question is "Can you change the Audio Input Device" fo Capturing Video in PP ?
I cant find it .. so I guess not.

Some more information which might help.
Below is a grab of a sequence I've created in PP to show what I'm seeing.
As you can see there are two clips in the timeline, the first pink clip is the finished AE comp which has been imported into PP via the file menu and placed into the timeline, both video and audio play, and are present in the timeline (in pink) so that is a work around if necessary.
The second clip in the timeline has been dynamically linked via the FILE MENU/ADOBE DYNAMIC LINK/REPLACE WITH AFTER EFFECTS COMPOSITION. The video effects that have been applied in the AE comp appear in PP but no audio and as you can see in the PP timeline the A1 is still the origonal file's audio track (in blue under the pink AE comp)

FCP audio noise during video transistions

Hi. I have a strange problem with FCP Studio 2.I captured HDV video onto my scratch disk using ProRes 422,and i finish all basic edits and use Livetype templates to generate lower third titles and drop a few seconds of AVI video to which i also add text using Boris text scrambler to superimpose text onto the AVI video in FCP. Once all is done and rendered on the timeline in FCP i can hear strange audio noise/interference a slight distortion of the audio track during any part where a LiveType title or AVI video has a intensive transition used with a audio track associated with the transition. The more intensive the video transition the more distorted (like a slight pop) the audio gets, it is noticeable. when there is no transitions, the audio is normal. Is this just lack of CPU power on my MacBook Pro causing this audio probelm?
Heath

Is everything rendered -no colored line above the video clips on the Timeline?
You might also need to check that all the render options are checked on.

Audio Noise in exported file

Hey all. This is driving me crazy and can't figure it out. Using Premiere CS6
I am editing 1920x1080 24p ProRes 422 footage, with audio being synced up from an external source. Audio is .wav 48 khz 16 bit.
I am increasing the gain by right clicking>audio gain, and bringing it up about 30 dB. The vocals are then where I want them, but there is a bit of audio noise. I apply the denoiser and make my adjustment and ALL of the noise is gone. First time I did this I thought it was a miracle because it sounded fantastic!
I went and exported my sequence, 1920 x 1080 24p ProRes Audio 48, 16 bit uncompressed.
And to my horror, where the audio bits come in, there is very obvious audio noise. It wasn't like this when editing the project, only when it was exported. In the sequence it sounds great.
I'm tried creating different sequences, exporting with different audio formats, but I can't figure this out. The rest of the audio, mostly ambiences and other sounds with no effects applied, sound great.
One thing I noticed, is that when right click and go to properties on the audio file it says:
Source Audio Format: 44100 Hz - 16 bit - Stereo
Project Audio Format: 44100 Hz - 32 bit floating point - Stereo
So apparently the source is different from the project? I would think Premiere could handle slightly different formats. Not sure if this is the issue, because I can't seem to select audio presets when creating a new sequence.
Thanks,
Dan

I'm trying that now. There is a noise removal feature that is a process, and one that is adaptive.
When I try the process, it takes away all the volume that was gained. When I increase the volume, the noise comes back.
When I try the adaptive process, I get the audio sounding good and how I want it (in the effects window that pops up), but as soon as I select okay to apply the effect, the noise returns in the main editor! <<<--- kind of like what Premiere was doing when I exported the file!

Creating audio test dvd

Ok, so how can I create a collection of samples to test out different audio settings (including bit rate) on DVD SP3? When I go to add another sample clip, I get the error message:
"one or more clips could not be added to stream. audio bit rate does not match existing audio clips."
is there any way to try out various audio settings on the same DVD?
thank you again
Bill

is there any way to try out various audio settings on the same DVD?
Yes. They just have to be in different audio streams - or levels, or "stereo track pairs"/ "surround groups" ie A1, A2, A3 et c. Treat it like selecting different languages. On playback, every time you press 'audio' on the remote it will change audio stream. It is also worth having an 'audio-select' menu.
So, put your other test versions of the sound on individual "tracks"underneath the vision track. Don't add them to the end if the bit-rate is different. (Note that they all have to have 48kHz sample rate.)

Final Cut Pro X crashes when adding transitions, throughout the entire program.

I've had FCP X installed for a few weeks now, and I decided to hold back asking my question and see if anybody else is experiencing the same problems.
I did find one matching problem on the discussions forum, but the user found a solution which I tried, and did it did not work.
Everytime I try to add a very simple transition to my video in Final Cut Pro X, it gives me the spinning colorwheel, hesitates for a few seconds and then crashes.
It only does it with transitions, I can add effects, adjust color, etc. but only when adding transitions does it crash.
I've tried deleting events and original media, I've reimported using optimized media, I've tried both ways of keeping files in original locations and also copying to final cut events folder.
The video I'm using is full 1080p mov files from a Canon 5D Mark II.
It does it in the timeline as well as the secondary timeline.
I've tried the solution that the previous asker did, which was copying the content to another FCP event, and it didn't work for me. Still crashes whether I try to drag the transition to my timeline, use the keyboard shortcut, or double click.
I have a Early 2010 15 inch MBP i5 with 8gb of RAM running newest version of Snow Leopard.
Hope I've provided enough information
Thanks,
-Jon

Same Issue: Added a transition and then beach ball from **** and crash. Also lost two hours of work when it restarted and reverted to the last planned quit.
FCPX is benched until Lion and updates. Don't have time to be a beta tester on what might end up being a hobbyists toy.

I can't create audio CD in itunes 10.3

I "upgraded" to iTunes 10.0.0.68 a while back. When I did this the various options for creating an audio CD vanished. I've scoured many apple forums & found lots of people have this issue. The feedback they get is generally insinuating that they are stupid because they can't see the "burn" button on the "advanced" tab under "edit>preferences>advanced" or they are not clicking the playlist or some other thing.
So what I'm saying is that none of the places I have searched offered an explanation. Eventually I decided to "upgrade" to 10.3.1.55 because most of the suggestions recommended that as a last resort. There is still no option to burn an audio CD or an mp3 CD anywhere in iTunes for Windows.
I'm running XP, I have two different burners that work with every single program I have, except iTunes. And it's really not that they don't work with iTunes, because iTunes would need to have a "burn" option somewhere in the program for them to not work with iTunes. And it does not. The only thing I can do is create a backup of my iTunes library. That is not what I need to do.
Does anyone know if iTunes is still capable of creating audio CDs? If so, please, please tell me your secrets! Thanks so much for any help you can give.

Okay, I may have answered my own question. When I have iTunes up, & I insert a blank disc I get a pop-up that tells me I've inserted a blank disc, if I want to burn to it, go to file>burn bla bla bla and sure enough, now the option shows up. Hmmm...
So here's what I did: I removed the disc & restarted iTunes to see if the option would go away. It did not. Even with no disc in the drive I now have the option "burn playlist to disc" under the "file" menu. It was not there 20 minutes ago, and has not been there ever with 10.0.0.68. I cannot say whether I ever inserted a blank disc while 10.0.0.68 was up or not, but I do know that I burned lots of stuff with other programs. My next experiment will be to completely reboot the computer, then start iTunes & see if the option is still there.
I'll let you know how that turns out. :-)
Here is my suggestion to anyone having the same issue: just pull up iTunes, then stick a blank disc into your drive & see what happens. I'm betting your issue will be resolved.

When adding ringtones (created by ringtone app) they show in music tab nor tones. the file type in 'get info' is 'ringtone'. Why is this?

When adding ringtones (created by ringtone app) they show in music tab nor tones. the file type in 'get info' is 'ringtone'. Why dont they display in the 'tones' tab in itunes? How can I get them to display under 'tones' not 'music'.

Well, I tried rebuilding the Launch services with the command listed but still no luck. After having no luck with that and deleting caches, etc....I also, went to my home (user) directory and in Preferences, I deleted the com.apple.launchservices.plist file. I restarted and checked and still the same result.
Also, I want to emphasize again that the file type I am discussing DOES actually launch with the correct application. (Cubase files in my example).
But it is just annoying that ALL of my Cubase files display the Pro Tools application icon, and in Get Info they are listed to open with Pro Tools. But they actually do launch Cubase if double clicked.
And one other VITAL note....if I open Get Info for one of these files, and change the Open With from Pro Tools to Cubase....then that choice DOES "stick" and retain. (if I "don't" also click Change All)
It's only when I click "Change All" that it DOESN'T stick and the list selection jumps back to Pro Tools. I hope that may offer some clarity.
Thanks for the tips but I am still back at square one.

What is a common way to create audio chat rooms?

What is an expected way to create audio chatrooms? Either try to mix all published audio streams into single one and republish it under common name? Or just inform all clients about each other and allow each one to connect to a stream, published by each other?
Do I need to write custom webapplication with my own scripts in it, or this is some default functionality?
Thanks.

I want all visitors to hear each other. User ability to mute himself is required, but user ability to mute other sides separately is not required. I.e. user is just hearing all sound in the room.
Also recording of room "ambience", which is consisting of voices of all visitors is required.
So, I wonder if mixing is possible at all? Does API have appropriate functions? Won't it load a server hard?
And if mixing is impossible or not recommended, then how is it possible to record entire room sounding? Is it practical to put individual visitor sessions separately? But how to place them in time correctly?
Thank you in advance!
Regards,
Dmitry
