IMovie 11 green screen - audio of the video in foreground won't play

Elementary teacher. Groups of students are creating movies and adding green screen effects to videos. In more than one group, the audio begins fine, but as the group edits (over the course of a day or two), eventually the audio in the foreground video stops playing. I see the audio waves, but do not hear the audio. When skimming the clip in the event library, the audio is fine. When the clip is reinserted, the audio plays. Nothing is ducked, muted or turned down.
Why are we losing the audio?

Thanks for the suggestion Brad, that makes sense... However, I was hoping there was a "straight" iMovie solution.
I'd prefer to not have to 1) spend any money and 2) use a program to do something iMovie is already supposed to do.

While in imovie, when working on a project, I can NOT view the project in the right hand screen. I have made several videos and it has always worked before. I am not able to edit the videos because they won't play in the right hand screen.

The videos that I import (and are located on the bottom of imovie) will show up and play on the right hand screen. But if I move that clip to the actually project area it won't play in the right hand side! I somehow must have clicked something that now won't play the project videos and now plays the clips below instead! Help please I need to fix this! Everythign else works, I can still edit videos, add transitions, music, etc I just can't see it on the right hand side- so I can't edit because I can't see

See my post here on how to do this.

I was making a movie on iMovie, and was trying to use the green screen to make a split screen. I pressed on the green screen button, but the second clip didn't play next to the first, and only the audio played.

I was making a movie on iMovie, and was trying to use the green screen to make a split screen. I pressed on the green screen button, but the second clip didn't play next to the first, and only the audio played. I tried again with some different clips and some worked and some didn't. This hasn't happened before. What should I do? (I am using iMovie '09)

"iMovie doesn't lock the audio to the video - it's an old, old problem"

Lot's of people have had problems keeping long video clips in sync with their audio in iMovie. I think what this guy says is correct:

"iMovie doesn't lock the audio to the video - it's an old, old problem either you import in short segments so the sound doesn't get too far out of sync or you buy Final Cut Express - it does lock the audio to the video".
...and unfortunately I don't know of a way to import in small sections if you've recorded say 4 minutes worth of continuous footage.
(Come on Jobs get it together!)

You can replace your internal DVD drive, or get an external DVD drive.
Note: If your Mac had an internal drive, the Apple external USB DVD drive won't work with it. It's designed to be used only with Macs that don't have internal DVD drives, i.e., MacBook Airs, MacMinis, etc.

On iMovie how can you mute a section of the sound track so you can hear the audio from the video clip?

.

Hey,
If you double-click on the soundtrack you can open it up in the inspector tab and lower the soundtrack so that you can hear the audio from the video clip.

IMovie "green screen" feature has serious problems.

I precisely followed the iMovie "help" instructions to make a green screen effect for what should have been a simple iMovie project... a 10-second video tagline for closing titles on a much more extensive project.
According to iMovie help, it should have been easy (and maybe even fun). It wasn't. Five hours of my life melted away forever. The iMovie "green screen" feature has serious problems. Remember that old Mac advertising campaign that said "It just works"? Well, it doesn't. Shame on Apple and the iMovie development team.

Folks,
I ran into the same issue (I named it "transparent green screen", I hadn't a better name).
I spent about a week to solve this problem, since I needed it to build a marriage slideshow.
The tools & Config:
iMovie 09, iPhoto 09, Adobe After Effects CS4
Mac OS X 10.6.2, MacBook Pro 13" 2.26 Ghz Intel Core 2 Duo, 2 GB RAM
The Solution for the "transparent green screen":
I created a movie in AE, and put a green background into it. It was the pure green color.
When I imported the movie into iMovie I just got the "transparent green screen", not the real effect.
I some cases, by changing the background images, I could get the green screen to work, but it was kind of random. Which made it harder to solve it.
I thought it could be because of AE, some incompatibility. I went to Youtube and downloaded a green screen video (a woman dancing in a green background). I inserted the video into iMovie, and it worked just fine, all the way.
Then I tried to match the green color I was creating digitally with the Youtube video's green color. It didn't work either. The "transparent" effect was there again.
But when I looked at that Youtube video, I noticed that the green color was not pure. Because that green background was made in the real world, it was not pure, there were some shades of green.
Well, I just replicated that into the digital world. Modified my video's digital green background. From pure green to a gradient green, but very subtle, almost imperceptible. Just to replicate the "imperfection from the real world".
That was it. Solved. Maybe iMovie 09 needs that imperfection to work well. Using "pure greens" might confuses it.
Please do your tests. And let me know your results.
Regards and greetings from Brazil.

Final Cut Express won't capture audio with the video anymore, why?

I have used Final Cut Express 4 for over a year now with no problems, but recently I am unable to capture any audio with the video from my camera. I can do it through iMovie no problem. I can't figure out if I changed a setting by accident because everything looks normal to me. Could another program be interfering with this? Quicktime Pro? I have no idea how to fix this.

First of all, we need a bunch of information in order to help. Please provide the specs of the footage and the sequence you are using. Also, are you using DV, HDV, or AVCHD? Do you hear audio when the clip is played in the viewer, or is there no audio at all once the clip is captured/ingested?

I can't find the green screen key in the Effects menu in Adobe Premiere Elements 12

Is there anybody who can help me were I can find the green screen key in premiere element 12. According tutorial video's on You Tube there must be a green screen key in the effects menu under keying, but with me it doesn't seem to be there.

jajajoja
Thanks for the reply. Glad you asked. Please check out my blog post on the use of the Difference Matte, especially for the Premiere Elements Mac users who run into this Windows Only situation.
ATR Premiere Elements Troubleshooting: PE11: Difference Matte As Substitute for Green or Blue Screen Key
We are not Adobe. Rather user to user. So, I am not sure why these keying features are not included in Premiere Elements Mac.
Please review and consider the above, and, if any questions, please do not hesitate to ask.
Best wishes.

Having a hard time lining up the audio to the video with FCPX.

Hi there
I'm having a hard time lining up the audio to the video with FCPX.
I'll just advise what I am doing.
I have recorded video of me playing bass guitar along to a song.
I have recorded the video in 720p with a DSLR.
I have recorded the bass guitar audio directly into Garageband (Using a USB interface) on a separate track to the song that I am playing along to. (It is played very well and is not out of time to the original)
I then mix the original song and the new bass guitar audio played by myself and export as an AIF in Garageband.
I import the video from the DSLR and AIF audio into Final Cut Pro X (10.0.5)
I can get the audio and video NEARLY bang on to timing, but its still ever so slightly off. As its ever so ever so slightly off it looks like I'm not really playing the bass guitar myself.
I'm moving the audio intricately but I just cant seem to get it lined up EXACTLY.
My camera picked up a tiny bit of audio so I can hear and see the audio wav on the video track to try and line it up with the audio wav of the AIF, but no matter what I just cant get it to line up and look exactly right.
Can anyone offer any advise or tips?
Thanks

Make sure you have Snapping switched off.
Expand the timeline to see the detail.
Rather than lining it up manually you could try the Automatic Audio Synch if there is any audio on the original video.

The Mac has never needed "Full Screen". It has done multiple screen Extended Desktop since 1987.
Full screen is an iPhone feature, carried into this verion with the mult-touch gestures and other so-called "unifying" features.

I am using FC Express HD, and for some reason, when I export a Quicktime movie, the final movie will only play audio, and the video is black. I only get the actual video if I export as self contained, or if I exportusing quicktime conversion. Why?
