Flip4mac exports out of sync

Hi all,
Suddenly, when I export WMVs using QT Converter (flip4mac) my clips end up out of sync. Any help would be appreciated - Steve

When I export a wmv the audio is always from the beginning of the sequence, regardless of where the in and out points are. For example, if I export a 30sec spot that's third in a sequence, the audio will be from the first spot. Or in my most recent try, tone from the bars that were at the beginning. I also get the other problems mentioned - it hangs up at 98% finished and the file sizes are three to four times as large.
I've had this problem for a few weeks, and it didn't go away after upgrading FCS and the OS last week.

Export out of sync, plays fine in FCP

I'm working on a short movie for a class I'm in, and everything shows up and plays fine when open the file in Final Cut, but for some reason, it doesn't want to export properly. Whenever I export, no matter what settings I've chosen, the audio and video become out of sync in the exported file, but strangely only for clips where we've chosen a different audio track from the original recording. The first clip, which uses the audio and video from the camera, works fine when exported, but for each subsequent clip, the audio starts close to synced, then gets further and further out of sync. Even more baffling, the final clip, which is done the same as all the others, with video playing and an external audio track synced to it, works fine again!
I'm pretty sure that the problem is with the video, as it seems to slow or have parts cut out of it in the rendered file.
Anybody have any ideas what could knock the video out of sync like that when rendering?

Motion project exports out of sync

Hi - I'm quite new to motion and have just learned to use it for keying - however I'm quite perplexed by the fact that whenever I export my finished project, it plays back out of sync. I am working at HDV 1080i50 mode, (fairly certain there is nothing telling the machine it's NTSC or anything...)
Does anyone have any ideas?
Best wishes, Dan

HDV files are probably to hefty to be using in Motion. Try exporting them as Pro Res and reconnecting them. You could also try to bring the Motion Project into FCP and exporting from there.... On other thoughts, does your project have a separate audio file being used? If so, You might want to export the audio file as another format or change it's bit rate.

Why is my video exporting out of sync with the audio?

Every time I export it (and it takes some 2 hours just to export a draft version) the video is sped up, but the audio isn't, so that the video is out of sync and at the end there's just black space with the end of the audio.
Both the video footage and the composition have the same frame rate (24p). I am exporting with Render Settings set to DV settings and output module set to Quicktime DV NTSC 48kHz
When I edit it I've been timing it to the seconds and frames because it's such a large file that I can barely RAM preview 5 seconds of it, and so it's especially frustrating that it's completely off when it exports.
Has this ever happened to anyone here?

Ahhh, right.
I'm using After Effects CS5.
The footage I'm using is in .mov format, although to be honest I'm not sure about the codec (I imported it straight to After Effects from my Canon 7D's memory card? I think it's H.264)
I also have some PNG sequences.
I used the AE Render Queue.

HD 1080i export out of sync

I'm exporting a HDV 48khz project to a quicktime.mov problem is once I get the export and play it, the sound is drifting along the project. It's not like it's out 2 seconds and I can slide it back into sync by making a 2 second adjustment, it has a different drift as the project progresses. It was captured at HDV 48 sequences HDV 48 and it plays perfectly in the timeline but when I export, it drifts. It is a long program 13 scenes over 3:10 but it's broken into 13 scenes.
I'm making an attempt to limit the file size to 2 gigs now, we'll see.
Anybody?????? Help PLEASE!!!! before I throw this computer out the window and take a hammer to it after it pathetically smashes into pieces on the sidewalk.
Thanx
Cal

What's the sampling rate of the clips and what's the sampling rate of the sequence. Although fcp SHOULD be able to resample on the fly, this might be the root of the problem.

QT exports out of sync

Hi
I have a 1:32 clip that I exported as a QT file. When it finsihes the length is only 1 minute 30 sec. The video is all there but the audio is cut off. THe audio is wav format 48K.
Any ideas why this happens?

I think I solved it. I copied all the clips on the sequence, opened a new sequence, deleted the render files and pasted the clips on the new sequence.
Seems to work now

Audio goes out of sync when Blu-ray folder is exported from Encore CS6

I compile a project in Encore using H.264 and .wav files. The audio plays fine directly from the timeline. It also plays fine when I preview it from Encore. When I finally export it as a set of Blu-ray folders, the audio exports out of sync with the video. It is approximately 6-7 seconds ahead of the video. What am I doing incorrectly? When I mux the files into an .MKV, the video is in sync with the audio so I know the files themselves do not have different start times.
I am running with an HP Z820 with Windows 7, 64-bit OS and 16GB RAM.

For anyone who's interested, I found a solution to this problem. Once imported into Encore, the leader in on the video and audio files cannot be trimmed at all. (I had been trimming the beginning of the video and matching audio file to eliminate the 8 seconds of dead space at the start of the clips.) Although the trim took effect immediately in the Encore timeline and I could also watch it in preview in sync, exporting was another story. The audio track seems to retain the trim when exporting but the video track does not, hence the 6-7 second delay between audio and video.
I reimported the files to my project and left in the 8 seconds of dead space at the start and voila! The video and audio match up when exported.
Ideally the trim tool would just work as its supposed to through export and all, but at least I found a solution I can work with.
(As a note, the trim works just fine in export on Encore CS5. I only had this problem with Encore CS6.)

Exported clips out of sync if I use Compressor

I have about 100 clips that I need to export from FCP to transcode to .wmv's. If I export to Compressor and use a custom .wmv preset there, the audio is out of sync. Not just a couple of frame as if it were 29.97 to 23.98 or 44.1 to 48 khz, but immediately about one second out.
I have checked my clip settings to make sure audio and video are the same for Compressor.
If I export using "Quick time Conversion" from FCP, then they are in sync. I would rather set a batch in Compressor than individually exporting 100 clips.
Clips are DVCPROHD/60, 48khz, 23.98 (I don't know why they were recorded 60p at 23.98)
Export settings: 1280 x 720, 23.98, 48hz, .wmv
Thoughts?
And, thank you.

I have seen more posts recommending that you not send files to Compressor from FC. Most recommend exporting a reference or a self-contained QT and then compressing the export.
If you are still having issues with the wmvs you may want to consider purchasing flip4mac(full version).
I prefer Episode to F4Mac or Compressor when creating wmvs but Flip4mac is the best option for the price.
I do not believe you can batch export/compress with flip4mac but the results are usually worth it.

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.

Audio and Video out of Sync after Pro Res export

I´m getting an audio/video sync issue when I´m exporting to Pro Res.
I started off in a HDV1080i50 sequence. Audio sampling rate is 48khz. (16 bit depth)
The sequence is less than 20 minutes long. It plays correctly on the timeline.
When I export the sequence for DVD and view it on a set top it plays absolutely fine.
When I export the video to ProRes (422 HQ - I used Export using Quicktime Conversion) and the audio to AIFF, they quickly go out of sync. This was brought to my attention first by the guys who were making the DigiBeta master, and when I view the exported material in a Pro Res sequence I can see it for myself.
The audio and video clips are of the exact same duration.
Possible issues...
Some of the narration was recorded at 44.1 khz. I didn´t resample it (I´m still a learning novice..).. but if that is the issue should it not have affected the DVD as well? All the other audio in the project is 48khz.
Most of the material is HDV1080i50..but one clip used was originally an NTSC clip and therefore a different frame rate. However I converted it to a 25fps clip and this is reflected in the vid rate column in the browser where it says 25fps.
Final point, the exported AIFF files..when I import them back into the HDV1080i50 sequence and play back, it is perfectly in sync.
Any help would be greatly appreciated.

First, yes resample the narration to 48k 16 bit. You will probably be able to reconnect to the resampled files. Usually works for me. That's a simple fix and will probably solve the problem. If it doesn't, you can try to change the codec (compressor) in the sequence settings to prores 422HQ, fully render and see if that solves the problem.
Wait, just reread your original post. Export from fcp using file: export: quicktime movie NOT quicktime conversion with current settings. If that works without synch issues, use compressor to convert to prores.

Audio and video out of sync after exporting sequence

I'm a FCP user since years, but not so common with HD footage. Therefore I have an issue with my finished edited movie after exporting: Video and Audio are out of sync.
My sequence settings are: HDV1080i50, 25fps, 48kHz, 16bit, Stereo. I used File-> Export-> Quicktime Movie -> Current Settings
Sequence has a duration of 61 minutes and 38 sec. I tried to find out where's the problem and exported audio and video seperated. This results in:
Video is 61 minutes and 27 sec long
Audio is 61 minutes and 38 sec long
That means exported video is shorter than original sequence.
What could that be ?

I had the same problem with a Panasonic camera, even filming at 30 fps. I was able to fix it; see [this thread|http://discussions.apple.com/thread.jspa?threadID=1783029&tstart=0]. It's a frustating problem, to be sure. You might have to use Easy Setup a couple times before you get things to work properly. Not sure why that's the case.
Good luck!

When I export a AAF file from Protools 9 and Import the file into Logic ProX the drum track is out of sync. I created the drum loop using NI Maschine. Has anyone else seem this??

When I export an AAF file/project from Protools 9 using an external drive and import the AAF into Logice Pro X the drum track does not play correctly. It is out of sync with the rest of the track. I created the drum loop as a plugin using Native Instruments Maschine. Has anyone else had this problem?? Also how would I go about exporting the midi tracks from the Protools session. The midi track does not show when the file is imported to Logic Pro X. The midi data should export with the AAF file correct??

Are you using any plugins in Logic?
In Preferences/Audio under the General tab, how do you have the plug-in-latency compensation set?

Why does my audio slip out of sync when exporting?

I am exporting an HD edited video. I shot 1280x720 & editing in FCP 6.0.5. I am using APPLE PRO RES 422 1280x720 30fps 48kz . Should it be (HQ)?? - I do not select re-compress all frames or make self-contained. I just want a QT reference file to view and then burn a DVD. My clip is 43 minutes long. HOWEVER, the audio drifts out of sync BIG TIME. Why is that??
Here are my sequence settings:
1280x720 Aspect Ratio HDTV 720p (16:9)
Square Pixels
H.264
Audio at 48kHz

That's what I thought, however, when I play back the .mov file after exporting using "current settings", that's when I experience OUT OF SYNC audio. Do I ignore that and drag and drop that file into iDVD and let iDVD crunch it??? Is it just the playback of that .mov file that is out of sync?

Some audio out of sync in after Export

Can using the built in Audio tools like Loudness, or adjusting the sound levels in the waveform cause the audio to go out of sync?
I'd say not...but that is what seems to be happening.
I have a 2hr 30 projet for a DVD.
All individual clips captured on Canon 5d 3 at 48khz 25fps
Project is 48khz 25fp, as set automatically when the clips were first dropped on the timeline
One particular group of 3 clips, seems to randomly and suddenly loose sync in the middle, sometimes at the start, some times in the centre, then often it comes back at the end.
Of the whole 2 hr 30 project only this bit is giving issues, all other clips have been edited in the same way, and are similar lengths,some longer, some shorter, all stay in sync. Max clip length about 8 minutes
In the timeline the audio stays perfectly in sync
I have re made the sequence of three clips , totalling 24 minutes long, probably 6 times now. and each time after adjusting the audio levels the exported audio has variable sync,
Also re imported the footage and tried again
No added audio tracks, just a single compound clip containing three complete clips, with the ends trimmed
Audio has not bee detached from the video.
All I am doing is adjusting the audio levels,
Hum On
Noise reduction to about 2%
Loudness On :
Amount 20%
Uniformity 15%
First noticed this yesterday on a DVD burnt using "Send To Compressor" Create DVD
Also happens using the in built Share, to DVD, ot share To master File
Output settings are also 48khz and 25fps
If I do an export of the clip With no audio corrections, it is fine. But as son as I try and adjust the audio levels, it goes out of sync.
I'd half suspected I had somehow dragged the audio in the timeline, when adjusting the levels, but no. Go back and play the clip in the timeline and it is perfect. But Share that compound by dropping in to a New project, export as master and Playback in QT and the audio goes out of sync after I have done a levels correction. Un-corrected ( for level only ) audio stays in sync.
o master file that single co

How are you exporting? The first quicktime export option or quicktime conversion? What are your settings for the export?
Did you capture with device control with abort capture on dropped frames and create new clip on timecode break enabled?

Final Export of a Project Slightly Out Of Sync

Hi there,
I'm trying to find an answer to what seems to be a common issue when exporting projects out of Final Cut Pro X, however I haven't yet found any answers that work or that tell me things I don't already know (don't mean to sound know-it-all though).
The issue is that after I have exported my project, the audio and video are out of sync. It doesn't drift as the video goes on; it's out of sync by the same amount from start to end. Of course, when editing and viewing the project in Final Cut, the sync is fine.
The project was created from scratch with the Apple ProRes 422 setting, the two original camera angles were both 25p, the audio I'm using is 48K/24bit which the project is setup as also. The audio was originally recorded at 48k/24bit and mixed seperately in Pro Tools and was exported as a wave file (48K/24bit) and brought back into Final Cut.
I can't think of what else to describe. All the project settings and the original footage and audio setting are exactly matched. There's no frame rate changes, no audio resolution changes, no MP3 in the mix, no apparent issue when viewing/editiing in the project, and I even tried optimising the video and exporting just to see if that made any difference.
I usually listen to the audio via an RME souncard which is setup to be low latency. However, whether I view the project and then export via the external audio interface, or view the project and export via the laptop speakers (with not extrernal audio interface connected) it's the same result: slightly out of sync video!
If anyone has any ideas I would be most grateful.
Cheers,
Chris

Hey Russ,
Thanks for your time. When I say a 'common issue' I found that when I searched it both on Google as well as this support forum I found multiple threads and questions pertaining to this issue of sync and/or drift.
I tested this single angle idea by using the footage in a nother project and exporting part of that (without changing angles) and it seemed to be OK. However I have other projects which are only single angle but they export slightly out of sync as well. I haven't found a common denominator yet.
When I say out of sync, it's not dramatic, however it's always the same - the audio is just a few frames behind the video. This has happened with most of my projects using different footage and different audio, etc. No matter what setting audio and video are recorded at, and regardless of whether I dramaticallty colourise or add effects to the video or not, it's always the same result; slightly behind audio when exported.
With regard to presets, do you meet export settings? If so, I'm mostly exporting using H.264 and as a Quicktime Move (AAC) output. I've tried various resolution changes and tinkering but nothing has changed.
If you're referring to project setup presets, I can't really change too many things because obviously the audio resolution and video frame rates are predetermined so I can't try 25p footage in a 30p project, etc.
Thanks again,
Chris
