Importing AVI into FCE has out of sync audio, but not in iMovie?

Hi all,
I'ave searched around and can't seen to find this issue in other parts of the forum, so thought I would try posting up. I'm using a GoPro camera which creates AVI files at 27fps, 512 x 384, Mono Audio, 8.0KHz, 32-bit Floating Point. I'm totally new to FCE, but when I drag these files into the project space and watch them on the viewer... it seems like the audio is almost 10 seconds ahead of the video right off the bat. It was the case with all 6 videos I had.
The crazy thing is when I drag these files into iMovie... the audio and video is sync'd up fine. Is there some setting in FCE that I'm missing that's causing this issue?
Any help would be greatly appreciated... I just went out and bought FCE because I figured if I'm going to start editing video more often... I should step up and of course I can't even get my raw clips to play correctly right off the bat
Thanks in advance for any help!
Jack

A DV-NTSC video file of 12GB should be a video about 55 minutes in length. If that's the approximate length of your avi video file, then you're probably good to go.
Have you brought the QT file into FCE? Did it behave properly?
FCE's learning curve IS pretty steep. You'd be wise to invest in some training material. Two excellent choices:

MPEG-2 file has out of sync audio - PLEASE HELP

We captured four mini-DV tapes into Final Cut Pro HD using my Canon mini DV camera and a firewire. After capture we put each tape on its own timeline, added chapter markers, and then compressed each one into MPEG-2 files using the QT codec. Once we had the compressed files we deleted the origional footage and burned DVDs with the MPEG-2s.
After viewing the DVDs we realized that the audio was out of sync on each of them. It seems to get pregressively worse as the tape plays (the beginning is close to being in sync and at the end it's a few seconds off). Each tape is about 59 minutes long.
We really need to fix this and do not have access to the orional/captured footage. Does anyone have any ideas?

You deleted the original footage before you verified anything !
Sorry, this is just <princess bride voice> inconceivable <pbv off>
Use MPEG Streamclip or DVDxDV to extract a DV NTSC file from the VOB files.
Drop that in the time line.
export the audio as an AIFF file
Open the file in Peak or similar application that change the length of the audio file without changing the pitch.
reimport the file to FCP
Re export the file as a m2v and burn a new disk.
Swear on whatever is holy that you will NEVER delete source footage again if you do not have access to original tapes/media.

AppleTV streaming has out of sync audio - anyone else having same issue?

Ive noticed since last updates to appletv and itunes that any mp4 file imported to itunes have very slight out of sync issues, enouth to be very annoying.... is it just me? i stream wirelessly usinga mac book pro and the latest appletv.

I've had this issue too. I found that if you hold down the select button (the big one in the middle) on the remote, you'll get a menu at the top of which is an "audio" button. If you navigate to it and select it, you'll probably see that "english surround" is selected. go down to just "english" and select that. This should take care of the problem, it does for me!
Hope this helps!!

Clip Within Multiclip Has Out of Sync Audio

I'm editing a 45 minute multiclip with 3 synchronized camera angles and one of the angles started to slip out of sync about halfway through whenever I'd click on it in the timeline. It started out okay and it's only that one angle, the other two are fine. What could've caused this and how do I fix it? Do I have to recapture and recreate the multiclip?
Jeff

First, which angle are you using for the audio...or are you using audio from all 3 angles?
Could be that one of the angle's audio is not right at 48khz...(like 47.999 or 48.001 or some such)...solution would be export that audio as aiff 48khz/16bit, then relink the new audio clip to it's video and recreate the multiclip.
Could be simply a dropout in your video capture that threw it out of sync, particularly if you're using only one angle as the audio.
You might try holding down control-shift and select the out of sync clip in the viewer and drag left or right to bring it back into sync. If it is drifting, you may have to do this several times over the remainder of the multiclip.
This solution will not affect any of your previous cuts...only the remainder of the clip, provided it's not been cut at later points in the timeline.
If that's the case, you can use that procedure where it's needed, or wait until you collapse the multiclip and address any out of sync cuts with your slip tool.

AVCHD to Blu-ray yields out-of-sync audio when not using TS

I have a need (won't go into too many details) to render my AVCHD project as separate M4V and WAV files; I can't have the output be multiplexed as a TS. However, the audio is horribly out-of-sync unless I output as a TS. For example, if I load up a timeline with ~40min of clips from my Sony HDR-CX12 AVCHD camcorder and render as Blu-ray H.264 1920x1080i, non-multiplexed, with PCM audio, the resultant WAV file is a full four seconds shorter than the M4V file! Ouch!! I'm guessing each AVCHD clip has just slightly less audio than video, and that it just adds up in the end, but why can't Premiere accomodate this? Is there a way to have it introduce delay at each cut? Obviously, the packetizing/multiplexing process for a TS accounts for this, but again, I can't use a TS; I need a WAV file that's in step with the video.
I also tried rendering a TS (which plays fine and doesn't have sync issues) and then demuxing with xport.exe, but this leads to the same problem.
Thanks for any suggestions!
Cheers,
Aaron

> Could this be a DF versus NDF issue?
Hmmm... every setting and Properties window shows 29.97... anything else I should look for?
> use a Time Stretching effect
I'll keep that in my back pocket for now. Doesn't seem like I should have to go to that length, however, but... Assuming the error in the source is relatively constant per AVCHD clip (maybe not a valid assumption, but seems reasonable), then the stretch effect would result in audio that was more or less out-of-sync depending on the density of cuts on the timeline.
Is it possible to create an audio-only TS using Premiere? Something that preserves the timing information? Seems not, but maybe there is. When I uncheck "Export Video", the option to create a TS seems to disappear :-(
Cheers,
Aaron

Trouble importing LiveType into FCE

I am trying LiveType for the first time with my video. I have created the file in LiveType and then tried to import it into FCE. When I view the background in the viewer it looks great. When I drag it to my movie and try Insert I get an error that says "Edit Operation had no effect. Check the target tracks. You may need to open the source clip into the viewer in order to see all of the target tracks". It doesn't add it to my timeline. I can drag it to the timeline, but when I preview the video it says unrendered as it plays. It has the red line in the bar above it and everything else in my video is green. I have rendered the video in LiveType and also just tried the LiveType file...
Anyone have any advice? I am sure this is something simple...
Thanks for your help!!

Appears to be a problem in LiveType and FCE as of Leopard.
LiveType files created BEFORE Leopard was installed import fine, but files created AFTER Leopard was installed will not import and return an error:
File Error. 1 File Recognized. 0 Access Denied. 1 file unknown.
Live Type files that are rendered as movies are importable and that is the workaround. But of course they cannot be edited again unless the Live Type file is reopened and re-rendered.
IOW, no import of a Live Type file directly into FCE.
Pro apps download doesn't appear to apply to FCE and you need a FCP serial # to access it anyway.
All suggestions appreciated.

IMPORTING FOOTAGE INTO FCE AND MERGING FILES WITH FINAL CUT STUDIO

So I recently purchased Final Cut Express to create off-line, rough cut projects...to be completed by more qualified editors other than myself. But I want to make sure that Final Cut Express is the right system for me.
Here are my questions:
1.) I will be using a variety of video formats for this system, and will be ingesting primarily through a shared media drive. Should I be concerned by the fact that it says I can only use "HDV, AVCHD, and DV" for simultaneous edit? What if I originate my material on Beta or DVCPro and want to import using firewire?
2.) Will my timelines be compatible to other (higher-end) Final Cut programs?
Any help is greatly appreciated!
Thanks,
Chip

Welcome to the forum!
1.) If the video you plan to use is not HDV, DV, or AVCHD then it will not be able to be ingested by FCE. The best way to get your media into FCE would be to capture it, but if it originates somewhere else you can still import it into FCE provided it is one of the formats cited above. If your media is not one of these three, you will have to use a convertor to make it "readable" by FCE. If you want to keep the full resolution of another format, you are better off directly going to Final Cut Pro, as it can handle these formats.
2.) Final Cut Pro will be able to open your Final Cut Express timelines, but you will not be able to go back the other way around. So only let your editors open the project in FCPro once you are done using it in FCE.
If you are planning to shoot professional videos, FCE transcodes into Apple Intermediate Codec, usually giving you lower quality then if you were to ingest the media in FCPro, which uses ProRes for higher quality yet larger file sizes. If you are not worried about the mentioned drawbacks to using FCE as a first-cut before FCP, then you should be fine.

Dropped frames or out-of-sync audio

Using Sony HDR-FX1 and FCE-HD is set to DV-NTSC. I've also tried DV-NTSC Firewire Basic. I've been trying various suggestions I've found in the Discussions to cure dropped frames that prevent me from capturing and out-of-sync audio making footage I do capture useless. Mac is running 10.4 with 5.5 GB of RAM and dual 2 GHz G5.
I'm capturing to my main hard drive which has plenty of space - when I'm done editing, I archive old footage on an external drive.
"Abort capture on dropped frames" is currently checked. Lately, this means I can't get more than a few seconds without the capture stopping. This never used to happen, now it happens all the time no matter what tapes I'm capturing from.
If I uncheck it, the audio on the captured footage is out of sync. Over time, as I've been trying to trouble shoot this using the Discussions, my projects remain unfinished and deadlines are looming sooner and sooner.
If someonce could please help me I'd be very grateful.

Hi(Bonjour)!
Did you shoot in DV or HDV ?
Did you try to capture HDV with Apple Intermediate Codec 1080i60 (or 50 for europe)?
Does you downconvert HDV shooted to DV upon capturing from camcorder ?
DV-NTSC 48 kHz is the way to go with downconverted material.
Does your DV audio setting is 16 bit on FX1 ? (HDV is a fixed one).

Out of sync audio markers

Why there are not out of sync audio warnings in final cut x?

Not sure this is the best place to ask questions about why 'features' are not in the application, but to give you a genral answer from the manual about what I assume you are pondering:
By default, Final Cut Pro imports audio and video from the same source into one clip. You can easily detach the audio from a video clip so that you can edit the audio clip separately in the Timeline.
This means that unless you detached the audio yourself, the clip is treated as one source. If you detach it, you are own your own.
If you are wanting to request a feature of some sort for Final Cut Pro X, try this Feedback Form.
Best of Luck!

Quicktime Export causing Out of Sync Audio?

I'm trying to export a self contained Quicktime movie from my timeline, and every time I try, the audio ends up being out of sync. What am I doing wrong?
The audio is set to just the defaults, 16 bit, 48khz.
Sequence settings: HDV1080p30
When I bring the final exported movie back into FCP, it plays out of sync.
Exporting through the Share feature to bluRay resulted in perfect sync audio, so I'm at a loss as to why this isn't working.
Please help!

Allright, since nobody out there seems to have the answer - I'm going to share what I discovered so that the next person will actually get an answer without having to spend hours and hours finding it in other forums. Here goes:
Problem: Audio plays in sync on the timeline, an export from the timeline through Share to bluRay results in correctly synced audio; but a Quicktime Export with current settings results in a final movie where audio is out of sync with the video.
Solutions: I found two solutions to this problem:
1- When exporting to Quicktime Movie, check "recompress all frames". This solution had mixed reviews, with lots of people saying you should never do this, as it will reduce the quality of your final output; while others said the reduction in quality was not noticeable to the naked eye. I guess you can try it and be the judge.
2- In your sequence settings, change the compression setting to Apple Pro Res. This is the setting I decided to go with, as I'm currently awaiting the 10 hour render.
I did do a quick and dirty test on the ProRes option, where it appeared to work. Since the audio is correctly synced in the beginning of the video and then slowly falls out of sync (obviously the 30p to 29.97 problem), I had to run a test using my entire sequence. If you run a test on a 2 minute sequence, it will appear to be correct, because it is a slow falling out of sync issue - the problems occur later in your project (just fyi). Here is what I did (in case you want to try it on your project):
I created a new sequence and then changed the compression setting from HDV1080-30p to Apple Pro Res 422. I dragged my sequences into this sequence (so they were nested). I unlinked the audio and then selected about a 20 second area from about 3/4 of the way through the project. I sliced this section and then removed all the video before and after (so it would speed up render time and only render black, but I would still be able to see if the audio synced up later - I hope that makes sense - this made my export time only 12 minutes). After it exported, I reimported the movie, found the little 20 second area, and it was correctly synced. So, now I am exporting the whole thing. I sincerely hope this works. I don't have lots of 10 hour blocks just lyin' around!
Since my audio issue was most likely due to the fact that I captured and edited in 1080 30p, I believe it must be a bug in FCP that exports the Quicktime movie in 29.97 regardless of whatever your sequence settings are (believe me, I tried to change it to 1080-30p and it didn't work). That is why I think the Apple Pro Res option works, but it involves a total re-render of your project. This is also why I believe it plays fine in the timeline, because my timeline was set to 30p. Again, I also believe that is why my export to BluRay through Share resulted in correctly synced audio - the bluRay export I believe uses the Pro Res codec (which, by the way, took 19 hours).
Wish Apple would fix this bug.

Out of sync audio six channels

Dear All,
I have not had a problem with this before, but suddenly I have out-of-sync audio when mixing six channels in FCP. Using my Canon XL1-S, I recorded 4 channels of audio in 12 bit mode, 32 khz. I then added another two channels of audio from a separate Sony digital recorder into the FCP edit. First I set the sequence settings to 32khz and ran everything in 32 bit mode, converting all of the audio through Quicktime pro. The 4 channels from the Canon XL1-s are in perfect sync, but the two channels from the Sony digital are playing at a faster speed and are drifting as the movie progresses...the length is 1:25:00. I then went back and converted everything to 48khz and changed the Sequence settings accordingly, but the Sony audio is still drifting and playing more slowly than the other two channels. What am I doing wrong and how can I bring all of the audio together? Thanks. I'm working with FCP 6.0.6 on a Mac Pro with Snow Leopard 10.6.6. Barbara Smits

What is the format of these Sony files?
. . . the Sony audio is still drifting and playing more slowly than the other two channels.
Unless you are timecode locked between devices, it seems reasonable to me that there will be sync drift if the Sony external recorder is not locked to the video signal.
You might try selecting the Sony audio clips on the timeline and adjusting the speed slightly, such as 101% and see if that gets you closer to sync.
Hope this helps

Here goes. My iPod touch has all my songs on it. I have changed computers several times and iTunes has a library of similar but not as many songs as iPod. When I plug iPod in ans go to sync it says that iTunes library will replace iPod songs.

That really does not work since music is not included in the backup. See:

PLEASE HELP ME.

Ok thank you SHANE for your answers.
I didnt explain the situation complete, sorry.
This is the story:
Im a new in a MAC WORLD'S and of course in a FCP too.
I never edited in HD (HDV1080i SONY HDR-FX1)
But i have to work ...
I HAVE a G5 QUAD CORE 2.5 512 MB RAM
and i buyed final cut studio 5
I installed the FCP Version 5.1 and i dont have any problem with captures HD FILES, editing or playing in FCP version 5.1 ** BUT*
I updated FCP 5.1 to 5.1.2 and the problems appaers
only in HD 1080i FILES the audio is out of sync video in a VIEWER and CANVAS

But i think
1. May be is a configuration problem OR
2. Software problema
I hope be explicit.
Please help me.
SORRY for MY English.

Audio/video out of sync (audio delay) with PowerBeats wireless earphones.

I am having a problem with audio/video sync between my PowerBeats Wireless earphones with my MacPro and MacBookPro. I have tried pairing, playing the video, pausing the video, turning off the PowerBeats, tuning the PowerBeats on, then starting the video playback again. I have the same audio delay so this not working for me. Anyone have an update as to how to fix this audio/video sync problem?

I am playing MPEG-4 movie files. I did open MPlayerX from my dock, then pulled down File to select Open which then did show the folder where these movie files are stored. Then I was able to select a movie file, open it, and use "Decrease Audio Delay" to closely sync the audio with the video. I say closely because it is not perfect. Rather than stepping each increase or decrease in one tenth of a second, perhaps a finer adjustment would have been in milliseconds. This is the adjustment that I have with my AVR to sync the audio with the video, so I know this is a possible increment adjustment. The perfect adjustment was in between -0.4 and -0.5 second,however, this was not possible in one tenth second adjustments. The closest adjustment was with -0.4 second rather than with -0.5 second. So, adjustments in milliseconds could have been very near a perfect sync. Perhaps later versions of MPlayer will offer the adjustment selection in milliseconds. Nevertheless, this is working much, much better than before. Thank you so much. I have spent most of this day researching this problem and you have come up with by far the best solution. This problem goes all the way back to 2010 and possibly beyond for Apple products. There are hundreds of reports documenting out of sync audio/video issues with no solution that works as well as MPlayerX. Even the Beats support staff have no idea of how to resolve the audio/video out of sync.
