Audio Speed

I filmed a wedding and want to add songs over top of the audio from the DJ because the hall had a lot of echo. The problem is that the DJ sped up the songs slightly. Now I need to speed up my songs but I can't figure out how. I know I can do it in Logic or Soundtrack but they would require a lot more work to get the right tempo as the video. Any tips?

This may be a longshot and you may have already tried, but select the audio track in your timeline and option+click. There you will find SPEED in the pop-up change it from 100 to a higher percentage and see if it accomplishes what you want.

Audio Speed change

Hello, does anyone know how to change the audio speed in FCP?
Please let me know.

Select (highlight) the clip in the Timeline and hit Command j to open the Speed control. Enter the speed you want. NOTE: speed changes may not take if a conflict occurs with another clip in the Timeline. You may need to copy the clip to an empty Sequence or to the end of your open Sequence then move it into place after the speed change.

Changing Audio "Speed"

I have a 35 minute video segment in Quicktime DV format. When I play the clip in quicktime, everything aligns flawlessly. However, once I import the clip into the FCP timeline sequence, the audio runs about 2 seconds behind the video by the end of the segment. FIRST, can anyone shed some light on what might be misaligning the audio and video? and SECONDLY, I have separated the audio from the video and am trying to figure out a way to change the rate or speed of the audio playback to sync it at the beginning and end to see if I can manually realign the audio and video.
Any suggestions?
Thanks!

What happens when you convert the file to DV-NTSC? The audio should be 48khz/16bit.
DV stream is not a native FCP editing format and is the source of all sorts of issues.

Audio Speed (2)

I posted this question earlier but unfortunately there's been no resolution. I was hoping someone might be able to help.
I have a project in Final Cut 5 where I'm splicing together a few MP3 files, making subclips, etc. - all with no video at all. My goal is to make an MP3 file at the end.
I have been trying to adjust the speed of certain audio clips. I tried CTRL+CLICKing on the clip, choosing Speed, and then adjusting the percentage but unfortunately all that does is crop the audio - it has no effect on the speed of the audio whatsoever.
I also tried exporting the clip to Soundtrack Pro but I've found nothing in that application that lets me speed up audio over an in and out marker.
Can anyone help?
Thanks,
Russ

FCP doesn't like nor work with MP3s very well. Only AIFF files at 48k, 16 bit stereo. And FCP is primarily a picture editing application, if you want to edit audio, you need to work with Soundtrack pro, Logic or Pro tools.
Now you mentioned that Soundtrack Pro doesn't work either. I am not sure that ST likes mp3s either, but I am not sure. Best to ask this in the SOUNDTRACK forum.

How to Create an Epic Rap Battle of History in After Effects (Compositing, VFX, Green Screen, Audio), or Fix Audio, Speed, and Real Time Problems

Hello. As a film project, I am creating an "Epic Rap Battle of History", a parody video of a popular series on YouTube. In my film/video, I would like to use compositing so that there will be two of one character in one shot. I have used Premiere Pro CC for the main character sequences, but when I imported this project in After Effects, there was no audio at all from the song, and the canvas displaying the composition was moving very slowly, at about 50% of the video's actual speed. Also, in the top right corner, it says, "Not Real Time", and displays something like 7.39/29.96. I have looked at different web pages, and nothing seems to work.
I would appreciate it if someone could explain how to fix this all up for me, or especially if someone who has had experience creating an Epic Rap Battle could actually list a step-by-step process on how to create one.
If this helps, I am a beginner to Adobe, and work on a iMac tower. Thank you for your feedback.

Audio Speed Adjustment Problems

Is there a freeware or Audacity plugin that will let me change the speed of an audio clip by entering how many seconds I want the clip to last?
Example, suppose I have a clip that's 60 seconds long. I want to extend it to 62.5 seconds (don't ask why; I don't even know myself). I could simply enter 62.5 seconds and it would stretch/squeeze the audio into that amount of time.
Keep in mind I'm working on a zero dollar budget here.
Thanks all!

Yes, you can adjust audio... I kind of got fed up with Audacity... Peak did this pretty well (when its preferences file didn't go south).
In Logic, you can press Apple + 9 to get to the Audio Window -- it'll list all audio files (or segments thereof) used in your project. Double-click the one you want and you'll be able to edit it in another window (I think this one's called the Sample Edit Window).
Under the Factory Menu, check out the "Time and Pitch Machine" -- there are a bunch of settings there that should meet your needs. Just keep in mind that the efficacy of these changes depend on the material you're working on. The manual discusses this in depth.
Also check out "Time Stretch" in the Logic Manual -- you can convert audio into Apple Loops, for example, which can change tempo and pitch pretty flexibly.

IPhone audio speed adjustment

I am trying to adjust the speed on my audiobooks after they have mysteriously converted to 2x. I have tried to use online instructions by going to settings and then to the ipod setting, but I don't have an ipod setting in settings...only music...but there is no way that I can see to make the adjustment through music. Suggestions?

Audio Speeds Up With WMV Files

I am a college student in a film production class. Our school computers have Premiere Pro on Macs and I have Premiere Elements on a PC.
For the last couple projects I have been editing in Premiere Elements on my PC and saving them as WMV files, and am using Premiere Pro to convert the files to MOV or MP4 because that is the required format for our assignments. But I have been having a problem.
When I take the fully exported WMV files from Premiere Elements and put it into Premiere Pro and try to move it to the timeline to edit it says that the clip doesn't match the sequence's setting. When I tell it to keep the settings it speeds up only the audio while keeping the video at the same speed. When I tell it to change the settings it speeds up the audio and also stretches out the video.
I do not know if this is the case for all WMV files, but it has been a problem with the ones that I have edited in Premiere Elements. The Macs at my school have no problem reading the original WMV files in the full quality I shot them in, it is only when I import them into Premiere Pro that I have the problem.
Any suggestions to how I could fix this problem would be really helpful!
Thank you!

I'm going to be doing that from now on. My college is a little bit of a drive, so editing on Premiere Elements saves gas because I was editing at home. But yeah, thanks for the advice.

Change audio speed of video file

I have a video file from the internet archive and its video speed is normal however the audio track is slow.
The video runs for approx 1 hour 20 mins but the audio track has been stretched out to just over 5 hours.
I am looking for a way to pack the audio back into its normal 1 hour 20 mins space.
Is it possible to fix this in premier pro cc? I am completely new to this software but I figure it will not be that hard. I'm just finding it difficult to find this issue elsewhere online.

Normally Premiere does not stretch audio on its own.
Could be the file has some exotic codec.
Anyway unlink the audio from the video (rightclick on file in timeline) select Stretch Tool and shrink the audio.
Hope this will work for you.

Audio speed from iPhone video

I have a problem with importing video footage shot on my iPhone 4s. The video plays at the correct speed, but the audio has been sped up. Funny though it is to hear people talking ike Alvin and the Chipmunks, I'd like to be able to use the footage. Any thoughts?
The audio plays fine when I play it back on my iPhone so the problem is definitely with iMovie 11.
Thanks

Fixed! Although not using the advice above... I re-imported them to iMovie a third time and they now seem to be ok. I have no idea what was causing the first and second imports to go awry. The only difference was that when I imported them for a third time the project was empty. My guess is that by having a project already partially done, iMovie was trying to force a change in the frame rate on import.
The tip on Quicktime will still be useful though as I'm considering a change in workflow, and potentially different software (Premiere Elements) after all of the problems that I've had with this.
Thanks for your help with this - appreciate the time that you took.

Video/Audio speed unsynced

The audio seems to play at a slightly higher speed than the video in Ae.
You don't notice it in the beginning, but after just under 40 min it reaches a few seconds. It's not relative to where you begin the preview, but to the work area.
No difference between auido and RAM preview.
Some of the material is in the ever-dreaded .mp4 format, but the problem occus for .avi aswell.
The problem is not composition-specific, as a separate composition, with only one 40-minute long avi layer, has the exact same problem.
I have not been able to determine wether it's the auido that's too fast or the video that's slow. It appeared quite recently, so it's not something with the files themselves.
Ae CS6.11.0.0378, I think
Demo version
7,9 g ram allocatable
Win7 proffesional
Only .avi and .mp4, can't tell much more than that
And don't tell me to extract the audio and add it separately. I wan't to solve the problem, not circumvent it.
Also, don't be suprised if i've just missed some obvious part of how it's supposed to work. I'm still quite new to this.

Thanks, dave. Correcting it screwed up my frame-frozen layers a bit, and crashed my after effects a couple of times (with an 17:18 error message that reappeared as soon as I removed it) before I got around to convert some of the mp4:s to avi, but in the end it seems to have worked.
" yes, that tiny-little variation makes a difference."
I'm not at all suprised. In fact, I suspected that it was a centimal or so that was the problem.
"I'd like to know how you're RAM Previewing a clip that's "40 FLIPPIN' MINUTES LONG"
It's really quite short.(Edit: 00:03:16:??) It's just that I accidentally placed it near the end of a 40-minute work area, and haven't found ot how to move the entire composition. Sorry if I confused you.

Audio Speeds up, sounds like chipmonks

I can record a great presentation and when
previewing or publishing, the audio track speeds up and sounds like
the Chipmonks for the rest of the presentation. Tried on different
machines with different mich's and had the same problem.

I had this problem myself, had something to do with the rate
at which the audio was recorded if i remember rightly.
Are you recording this audio externally from Captivate and
then importing?

Pitch compensation for audio speed change?

Is there a formulaic way to compensate for the pitch change after a speed change on audio?
- control-click on an audio track
- select "Speed..."
- change the speed (for example 130%)
- now, notice the speed has changed, but the pitch is now higher
- there is an audio filter for this: AUPitch
- BUT: how do I figure out what the value for the "pitch" setting should be to get it back to roughly the pitch it was before I changed the speed?
(From trial and error it looks like it's around -400 for a 130% change)

hello monkeywidget,
if memory serves, the audio pitch works in cents so 100 cents = 1 semitone; 1200 cents = 1 octave; 200% speed = double speed = 1 octave up so -1200 in the pitch shift would compensate.
you'll have to experiment from there, but that'll put you in the right direction.
by the way, the audio filters in FCP are crap (since apple doesn't do good audio software? ... ) so i'd only use the internal filters as temp.

MediaPlayBack component audio speed

If, i've following the basic instructions for using the
mediaPlayBack component:
drag to stage, set to MP3, target a *.mp3 and publish.
fla, swf and mp3 are all i the same folder.
Works fine expect teh mp3 is being played back liek a
chipmonk - doubel / maybe treble speed etc.
why? i can't find a setting to control this?
help, Rich
Ps. Win XP Pro SP1, Flash Pro 8

Yes your correct. Here's something I found on the subject:
From here
http://odeo.com/help/faq
What's with the high speed playback on some audio?
You’ve been chipmunk’d! Sometimes the Macromedia
Flash player has a hard time dealing with files that are encoded at
a rate that is not a multiple of 11.025 kHz. The result is what we
call the “chipmunk” effect. When you download the file,
it will play normally on your computer or device. Note to audio
creators: Avoid being chipmunk’d by encoding MP3’s at
11.025 22.05 or 44.1 kHz.

Editing audio speed

So i have 4 audio clips that all together are 00:36 long and i need them to fit within a 00:30 timeline. How would i in FCE speed them up to fit within 30 seconds? is there a way to shorten the duration or increase the speed of each clip or all of them together?
I have tried the duration and speed controls in the modify menu and both result in the audio clips being cut off or stretching out to include content i had cut off.
thanks,
dp

I'm no FCE expert but I'll try to explain. I'm not the detail of your project, but when you place clips or audio in the timeline they are contained within a sequence. You can have multiple sequences within your project, each one containing media for your project. These sequences can be placed within one another (called nesting). The purpose of this is (I believe) to create smaller more manageable "scenes", which all ultimately get placed together in a MASTER sequence.
The idea I proposed was to have your Audio in a sequence of it's own, no video, as I understand you wish to just alter the speed of the audio. You can then take this sequence and place it in your MASTER/MAIN sequence. It will appear as one audio clip, though when you play it, it will contain all of the audio you have placed in that sequence. So when you modify the speed of the Audio sequence from within the MASTER sequence timeline it will change all of the audio clips at once, and should (this is the part I'm not 100% on) keep then all at the correct In and Out points, and at your original edit points.
Once your at this stage you will have to do trial and error to modify the speed to get the audio down to around 30 sec.
I'm not usually the best at trying to explain these things, but if you look up in the FCE manual "Sequence Nesting" it's pretty well explained. I've suggested this method as it will give you, what appears to be, just one audio clip to concentrate on modifying and moving around in the timeline, hopefully making it easier for you to achieve what you wish.
Hope this helps.
