Sync issues on Capture of DVCPRO 50

The tape was recorded is fine. It plays back with no inherent sync issues - both to an external monitor and through the FCP capture preview window. But when a captured clip is played back, the audio drifts more and more out of sync the longer the clip gets. This is what I believe to be an issue with Final Cut Pro.
We worked this same setup last year, and it didn't give us any bugs like it is now, and I can't see what the problem would be in this configuration. We are using the easy setup "DV50 Anamorphic" and everything seems to be fine, but the audio drifts on each tape.
We shot the film on a SDX900, with DVCPRO 50 tape stock, and had to channels of audio(boom and lav) and then we're capturing using a Panasonic AJ-SD93 deck through Firewire. We did the same process with the same equipment last season with no issues. Is there a bug in the 5.1 version versus the 5.04 version???
Anyone with any idea how to resolve this issue please help me? Thanks

Audio/Video Syncing Issues on Capture

Hey guys,
I've imported several tapes from my Sony V1u HDV camera, and I've been having the same issue. I am capturing the video over Firewire, and every tape I capture, the resulting MPEG file in Premiere Pro is not in sync. The video and audio are there, but they are not lined up at all. Any ideas as to why I'm having this issue? Thanks!
Cody

Sorry for the confusion. To clarify:
The Video and Audio are OOS. Let's say that at the beginning of the Clip, the difference is ~ 12 frames off. Is it still that ~ 12 frames off at the end, or is it now ~40 frames OOS?
Though the best is to Capture with no OOS issues, the former is fairly easy to fix. The latter takes more work.
Also, whether the OOS is constant, or dynamic, might lead to figuring out where this issue is being introduced.
Good luck,
Hunt

Sync issue with FCP DVCPro HD 720p 60 w/wire less mic

I just tested with DVCPro HD 720p 60 w/wire less mic, the audio was drifted in FCP. Can some please explain the specific of frame rate of video and audio sync issues.

Was the audio routed to the camera? Or recorded separately?
Which camera?

A/V out-of-sync issue for FCP captures

I've read many of the out-of-sync posts on this board, most of which seem to indicate that the problem is usually caused by either dropped frames, bad timecode breaks, edit errors, or disunity between FCP capture and sequence settings, compared with audio sample rates for the underlying files.
My files, shot on my Panasonic AG-DVX100A in 24pa mode, result in perfect (except for the anamorphic screen size - see my next post!) Quicktime movie files, in perfect sync. It's only when I create clips from those files in FCP that the video and audio go out of sync. And the out-of-sync drifts; that is, the further you go in the clip, the more out of sync the sound and the video gets.
My camera is always set to the 24pa mode, which, by default, records only in the non-drop-frame mode, regardless of any other camera settings I may have selected. The audio settings in my camera (and in the resulting underlying QT files that are created when I capture in FCP) are 16-bit integer and 48.000 khz, as they are in both my FCP sequence presets and capture presets, so I don't think it's an issue of conflicting sample rates. My device control presets are for Firewire NTSC NDF (non dropped frame).
Given the above information, does anyone have any idea what else I might be doing wrong? I've already shot hundreds of hours of footage last year that worked fine. I don't know what I changed to cause this out-of-sync problem now, but I'm going bald tearing out my hair trying to figure it out.
Thanks in advance for your help!

The dvd recorder was in the loop when the sync issue showed up. the dvd was in sync but the live stream, next in line, was out of sync. I have returned to using the older machine with xp. (the lap top is running vista) The older machine is a desktop which requires more space on the production table and time to set up.

How do I get rid of lip-sync issues with iTunes 10.2.2.12?

Hi Everyone.
Firstly, a very Happy Easter!
I'm having lip-sync issues with iTunes playback on my PC. The video is largely smooth with the occaisional choppiness when the CPU is made to work hard. (Playback on my iPod Touch is fine).
The system stats for my PC are at the bottom of the post.
The sound is produced through a Creative Live Sound Blaster Live! 5.1 card.
Video is through a NVIDIA Geforce 6200 with 512Mb of RAM. (All video and audio drivers are up to date).
The physical set-up is that I have iTunes installed on the C drive and my media installed on an external USB hard-drive.This isn't just a problem with 10.2.2.12 - it's been there for the last few updates.
I suppose my main questions are:
Should iTunes and my media be on the same drive? (Which would mean the external drive as I'm short on space on the C drive).
Is there some combination of settings in QuickTime that will solve this? (I've tried different combinations, but it doesn't really help).
Is the spec (below) of my PC causing any issues.
Here's an Easter Egg for anyone able to help!!
All the best

Multiclip sync issues - resolved???

Searching through the threads here I've seen a few different posts regarding the loss of sync in multiclips when moving media files around. Unfortunately all of the threads are locked and can't be posted to. None of them have been answered!
I've just run into a similar situation and am trying to find out if the recent update to FCP 6.0.3 has fixed this. My problem, which is 100% repeatable is as follows:
Create a new project/sequence.
Capture 2 camera tapes from the event (1 w/ timecode, 1 via a analog to digital converter, ie no timecode)
Review each captured clip and insert markers where I want to use scenes.
Create subclips from each marker I want to use
Mark In Points in each subclip to use as sync points (clapper board in my case)
Select the corresponding subclips from Camera A and Camera B and Make Multiclip using In Points for sync.
Place multiclip in timeline.
Play sequence and use keypad to insert camera changes.
Save file.
At this point everything is fine. My sequence plays back with all of my angle changes.
Now if I quit FCP and use the finder to move one of the captured files to another hard drive everything goes to sh*t. When I reopen the project, FCP will ask me to reconnect to the offline media file. No problem; use the dialog box to locate the moved file and reconnect. Now when I go back to the sequence and play it, the 2 camera angles are completely out of sync with each other. I'm not talking a few frames, its usually several seconds at least.
I've done this several times, and it always happens. FCP absolutely cannot maintain multiclip sync info when a media file is moved.
Just as a point of further frustration, I know someone is going to respond that I should use the Media Manager to move media files around. This is also broken. That's how I originally discovered the problem. I went to create an archive of the whole project. My destination was an external hard drive. When opening up the newly created project, I saw the same out of sync multiclips. My guess is because the media files were now on a different hard drive.
Also, try to roundtrip a multiclip sequence to SoundTrackPro - totally hosed when it comes back into FCP. Same out of sync issues.
So something is definately problematic here. I'm still on 6.0.1 and can't risk updating while this project is in process. But I would like to know if this problem still exists in 6.0.3.
Thanks,
Chris

Chris-- I am having the same problem-My media went offline-- tried reconnecting and get this message stating that the attributes of the original clip have changed; mark in and out-- then when i reopen my sequence certain clips that are multicam have suddenly got different ins and outs-- have no idea what is causing this but here is some advice someone posted on another forum:
I do almost nothing but multi-cam editing, and have for the last 8 to 10 years, but the overwhelming majority of my work is with matched time-code cameras. I have worked with in-points on FCP and have not had these problems, but I don't do it that often, so I don't feel comfortable telling someone that he's not having the problems he is having.
Jasper - when making multi-clips with in-points are you using master clips or sub-clips? Also are you sure you haven't seperately used the same source clip and thereby changed the in-point reference? These would be the first 2 things i would test when trying to figure out why the multi-clips were not functioning. Also I will say the a sure way to get corrupted multi-clips is to use a clip that has time-code breaks within it - something that shouldn't happen, but that actually happens all to easily in FCP.
Finally I can offer this work around, change the AUX time-code on the clips and sync with them. FCP makes it incredibly easy to change the time-code on a captured clip, and that includes 2 optional AUX time code tracks that are available for each clip. Find a sync point on each of the clips that you want to use in a multi-clip, go to Modify / Time Code - check the AUX TC 1 box and enter a common time code in the window - I would recommend that this time code be a copy of the actual time code of your most important clip, but anything will do - and then when making a multi-clip choose to Sync with Aux 1. (just don't uncheck the box containing your source time-code or you'll loose it - leave both boxes checked) - this extra step does not take long and should alleviate your problems.
hope this helps?!@

XMPSES file extension and Out of Sync issues

I captured a VHS tape to an AVI. If I watch this file using Windows Media player, the audio and video are in sync. I then imported the AVI into PE11 and created a video project. I selected the MPEG option for Computer under Publish+Share. I did not change any settings. The preset is NTSC DVD Standard. When the project was complete, I now have two files
FILENAME.MPG
FILENAME.MPG.XMPSES
Also, when I play the .MPG file using Windows Media player, the audio and video are out of sync. The audio is delayed by a couple seconds.
I am using Windows 8.1
Does anyone know why PE11 creates the two files? Is this related to the sync issues?
thanks,

uberjaeger
That .xmpses is an informational file attributed to Adobe and described as a Premiere Elements DVD Marker File (has information about DVD marker project, chapters, titles and scenes). I can confirm its existance. I do not suspect that as the source of your out of sync audio in your Publish+Share/Computer/MPEG with NTSC DVD Standard export.
How did you capture the VHS tape to AVI and what type of AVI did put on the Premiere Elements 11 Timeline....DV AVI? If DV AVI, was it type 1 or type 2?
What were the properties of this import into Premiere Elements 11 - 720 x 480 4:3 @ 29.97 interlaced frames per second or something else? What did you use for Add Media?
What was the project preset of this Premiere Elements 11 project? Did you set the project preset to NTSC DV Standard manually before the Add Media or did you let the program automatically set the project preset based on the first video drag to the project's Timeline? If the program took charge, what did it set? Please see Edit Menu/Project Settings/General and the readings for Editing Mode, Timebase, Frame Size, and Pixel Aspect Ratio (even if grayed out).
If you take your Timeline directly to Publish+Share/Disc/DVD disc, does the DVD-VIDEO standard on DVD disc play back with out of sync audio?
By the way, do you have the VLC Player and does your mpg play back with audio out of sync there?
Let us start here and then decide what next.
Thank you.

FCP6 - Audio Sync Issues on Existing Clips

I recently installed the FCS2 upgrade on my MacPro desktop. I opened an existing project (with mostly 24p timelines) and there are some clips where the audio/video are not in sync. When I play the clips back from the Finder in QuickTime, they play perfectly fine. When I try playing them back in FCP6, in the Viewer window or in the timeline, the audio is not in sync.
A more accurate description would be: it's actually a VIDEO sync issue. When I get to a clip in my timeline that has this problem, the audio is accurate, but the video plays back a few seconds behind. Another observation: When I play the clip in the viewer from the beginning, the audio is in sync, by the middle it's off a little, then by the end it is VERY out of sync.
My preliminary diagnosis is that FCP6 is not interpreting the 24p files correctly. I've tried disconnecting and reconnecting the media hoping it would help but it didn't.
Sorry for the long-winded explanation. Is anyone else having these issues? Any suggestions? Thanks.

Update: In FCP6 (it may have been in FCP5 but I never saw it or used it) there is an option under Tools->Analyze Movie->Clip. When I run this against a clip that works ok, everything comes back normal. When I run this against a clip that is not working properly, it says:

Since these clips have not changed since my FS2 upgrade, then there is a difference between FCP5 and FCP6 handle these "dropped" frames. Whereas FCP5 was more forgiving and kept the audio in sync, and FCP6 does NOT.
Does anyone have ANY idea how I can get this resolved?

Audio sync issues with variable frame rates as well as .ts files

I'm using Premiere Pro CS6 and CC, in Windows 8.
I bought an AverMedia Live Gamer HD card to capture 1080p footage with, and the the videos it produces work perfectly during playback. No sync issues whatsoever. I'm saving them as MP4 at 30fps.
The problem is when I import them into Premiere Pro, the audio loses sync at certain points. After a bit of digging, I've discovered that the videos have a variable frame rate, which Premiere Pro does not support. I don't know why, considering competing products that are significantly cheaper can handle them with a problem, but oh well. The capture card can also save videos in .TS format, which produces a constant frame rate, however when I import them into Premire Pro the sync is immediately off by a second or more. I assume this is for an entirely different reason. Again, they play back normally without a problem. Upon emailing AverMedia, I was told this was Adobe's problem and there was nothing they could do about it.
What I'm wondering is if there is any sort of realistic solution to this as of now. Is there any way that Premiere can work properly with files that have a variable frame rate? If not, is this being worked on?
Or maybe there's a way to get the .TS files back in sync, that way the variable frame rate issue doesn't matter anyway.
Converting the files is not a long term solution. I'm working with hours and hours of HD video, and it would take way too much time to do this.
Manually resyncing the audio is also not a solution. Again, this would just be way too much wasted time with each project.
The only solution I see as of now is to switch to Sony Vegas until this problem is resolved in Premiere, if it ever is. I'm really hoping there is some other way, so if anyone has an idea as to how to fix this, I'd really appreciate it.
Thank you.
tl/dr:
Is there any way to get around Premiere Pro not working with variable framerates? My .TS files are also out of sync, is there any way to fix that? Without converting or manually resyncing.

>If not, is this being worked on?
Discussed many times before... never a "yes" answer to your question... tell Adobe what YOU want at https://www.adobe.com/cfusion/mmform/index.cfm?name=wishform
If enough people make a request, Adobe MAY add the feature (I don't work for Adobe, so no guarantee of anything)

Canon cameras have audio sync issue with FCP?

My mini dv deck died on me so,
I am using a small palm size Canon mini dv firewire camera to transfer about 50 tapes.
I am having a weird audio sync issue.
Sometimes the capture footage plays down in sync - I pause>scroll>play - and it's suddenly out of sync. This keeps happening. Sometimes it plays in sync. Other times it does not.
Because it's hit and miss- I'm not sure I can even re-sync.
I imagine it could be the media drive (internal)- but I have other video files on this drive that play fine.
I don't often use firewire capture.
Is audio sync a common firewire issue?
Will the quality suffer if I capture through composite/analog audio outputs?
I can patch it through my
decklink card.

Audio sync is an issue with Firewire, just not all the time. Usually it is fine, but a lot of Avid people don't like Firewire for this reason.
Most often it is a 5 frame sync issue. Slip your audio 5 frames forward and see if that solves the problem.
As well, take a look in your Browser after you capture a clip and see if the Aud Rate is either 48,000.5 Hz or 47,999 Hz. I have seen the clips come in as both of these. Once you slip the footage, export the audio only, then reimport and attach the audio to the clip in the timeline. Should take care of it.
Post back if these don't work.

VHS Import Audio Sync Issues

I have been attempting to import VHS videos into FCP. The video and audio comes through fine, save the fact that the audio will gradually work it's way out of sync.
I use a VCR linked RCA to a Sony DV converter, which is then connceted to my Mac via firewire. I log and capture as a Non-controlable device.
The audio starts out in sync but starts to become noticably out of sync after about 10 mins.
I'm wondering if anyone out there is knowledgeable about this issue or has encountered anything similer, and could help. I don't want to trouble shoot this one on my own, seems very time consuming due to the long import times.
My thought is the capture settings may need to be different for VHS. Though I do not know the one to choose.
That there may be some data stream issue that my computer is attempting to compensate for.
I'm at a loss. Any help= great!
Thanks.
iMac Mac OS X (10.4.9) Sony DV converter. VHS-RCA-FIREWIRE-FCP

Welcome to the forums!
There are several things that could be the problem here but I am willing to bet that there is one that is the most problematic. Answer a few questions if you will.
1. Do you have FCP set to "Abort Capture on Dropped Frames"?
2. Are you using an easy setup? If so, which one?
3. Does the sync get gradually worse over the course of the material or is it just out of sync by a certain amount the whole way?
OK, here's my guess...You probably have it set to NOT abort on dropped frames and between the fact that you are capturing VHS through a converter you are probably dropping frames and that is causing the sync issue. It seems that FCP will drop a video frame and still capture the audio, but it doesn't insert a black frame so your audio and video gets out of sync.
I have had to capture a lot of VHS and old 3/4" material and this is a problem. The best way I know around it is to dub your VHS onto miniDV, DVCAM, Beta or something that you can capture with confidence. This can be done with a camcorder or deck.
Hope this helps,

FCP 7/ Sync issue in the canvas and viewer-not in timeline.

I am using FCP 7 on a Mac Pro. I am seeing an audio/ video sync issue in the canvas and viewer if I display at anything less than 50%. at 50% the video is choppy, but will play in sync. If I adjust between 50% and 25% or less, I can actually see the frame change without moving the play head. Has anyone else experienced this and found a solution?

Thank you for the advice MtD. This content was encoded using H264 compression, but I have the option within my media encoder application to create only i frames-no B or P frames. This gives me a high quality file that is supposed to be much more "edit friendly" than standard H264.
I'm in an environment where re-rendering to Apple ProRes is not always an option. I have imported H264 content before and found no issue when trying to playback in the canvas. One odd thing I did encounter with my "problematic" file is that though I capture this at 23.976fps, Quicktime Player identifies the frame rate as 23.97fps and Final Cut then interprets this as 59.94fps. I thought this might be the culprit, but even after adjusting my frame rate to 23.98fps, and FCP7 importing as 23.98fps-the odd sync issue still appears in the canvas when displaying at less than 50%.
I will take your advise and re-render to Apple ProRes when that is a possibility.
Thank you.

FCP audio sync issue, attempts at fix result in dodgy files - help!

Hello,
I have some Sony EX1 footage here in which 20 out of 500 QT files FCP will play the audio out of sync by either 14 or 19 frames (picture lags) - when shooting no changes were made to settings which were as follows:
1080/25P HQ 16-bit 48Khz
weird thing #1: only FCP will exhibit the out of sync problem, QT or even quickview in the OS X finder will play them back fine ...
weird thing #2: once I export the footage without re-syncing it it will then play fine again in QT/finder and will sync fine in FCP - yay! - no... it will beach ball and/or lag/crash FCP/QT/finder once I attempt any sort of movement/scrubbing in any of the timelines
attempting to work with the original un-synced footage and unlinking the audio (and correctly syncing it) as a workaround has failed as whenever I put on any video effect/transition or whatever the effected part will sync correctly and my smarty pants re-sync therefore makes it out of sync again ! arrrrgh!
Basically, anytime I effect or export it the sync issue goes away, but I am left with crashy/corrupted files ...
Any suggestions ?

the audio clip is the same length as the video clip. it is not a matter of moving the audio over to sync it up. the audio falls behind by the time it gets to the end. it is just fine at the start of the video and out of sync at the end. If I would sync up the end then the front will be out of sync. All I did is capture the footage from my deck to FCP and then placed it in the time line.

This is not correct but it's easy to arrive at that conclusion. The two clips aree not the same length by your definition: *the audio falls behind by the time it gets to the end*
Mark the place where the audio ends, mark the place where the video ends. They are different and that difference is a simple matter of subtracting one timecode location form the other. This means the audio was shot at a different sampling rate than that with which it was captured. I do not know anything about the DSR400 camera or your deck, my Sonys are different, but you should be able to ascertain the sampling rate of the audio by checking the data display. If, indeed, it's 48k, you have sent the audio to a separate folder than the video and your disk cannot keep up. But that sync difference is not absolute so it's going to be different each time you play it back.

TIMECODES are important for audio and video sync issues

Hello, just wanted to pass on what I learned so that others can avoid the trouble that I've had to go through. Perhaps this may help someone who is stuck on the launch pad. :)
BOTTOM LINE: Info for the beginner. Audio and video not in sync in Premiere Pro CS3 V3.2.0
PROBLEM: Capture works great it seems. When I go to the folder that contains the captured file and view in Windows Media Player audio and video are in sync. BUT when viewing the video asset in the source and program monitors, the audio and video are not in sync.
SOLUTION:
Before capturing a tape make certain the following is checked:
(1) Edit->Preferences->Capture->Use device control timecode
(2) Edit->Preferences->Device Control->Options->Timecode Format
(3) Project->Project Settings->General->Video->Display format
As for the devices timecode choose something other than Auto Detect. Then match the project timecode with what was chosen during capture. The projects display format could of course be set to frames.
I searched everywhere for audio and video sync issues in google, adobe forums, F1 help, and hv20.com and everyone was talking about:
(1) Presets: 1080p30 vs. 1080i30 (60i).
(2) brakes in the tape where timecode for the audio and video get misaligned during capture.
But choosing the correct hardware settings and timecodes to solve audio and video sync issues never popped up.
MY HARDWARE: Canon HV30, HDV

>Audio and video not in sync in Premiere Pro CS3 V3.2.0
Must be an HDV only issue because my synch is always perfect.

IMovie 6 Audio Sync Issues

I have a Canon HV10 HDV camcorder and I am having issues with my video and audio being out of sync in iMovie. I have not attempted to move the movie to iDVD or QuickTime. My movie is a little over 28 minutes. I have the limit scene length setting set to 2 minutes. I am recording in 16 bit audio - not 12. I have made a few very small movies with this camera without issue. This is the longest movie I have imported so far. I have about 66G of hard drive space prior to import and about 48G after.

Kurt,
I have been following this thread and although I have a Sony HC-3 I share your pain. I do not have audio sync problems after importing its only when I add transition between clips that I have sync problems.
The long and the short of it is that there seems to be an issue with any and all HD content with iMovie. From what I can find here and on other forums is that the audio sync issues comes in a couple flavors.
1. Audio sync with 12 bit audio. iMove does not like 12 bit audio stream, find out what kind of audio stream your camera has, many have 12 bit audio to allow for stereo sound with minimal space on the take, 16 bit takes up more and usually is mono sound.
2. Even 16bit Audio streams have issues with HD content. Not so much when you capture its when you perform any editing that involves the transition of audio where iMovie must manipulate the stream in some way.
Now with that out on the table, what is Apple's position on this?
Items they have had me try:
Clear the Cache's and settings, re-install the program (iMovie), and the last thing they told me was, "Well iMovie is not a professional product and it is not going to be perfect".
My opinion is that they have not or will not attempt to research this issue because they do not feel it is a wide spread issue OR they are working to develop the newer version and hope that resolves the problem.
Lastly I have Final Cut Express HD, and I am here to tell you it does not express the same issues as iMovie although it take a little more effort to produce the same results than it does with iMovie.
I am confident that there will eventually a solution for this an other issues, it just takes time and effort on others to resolve. I am grateful to others here in the forums and I know Apple support keeps their ears to the pavement when it comes to the forums, but lets face it unless many. many people contact the Support department with Apple nothing will get done. It's next to impossible for everyone here to experience the same issues you and I are having, so that is why these forums are so useful. People helping people, keep up the good work everyone and I know I am grateful to any and all help that is given here in the forums by others willing to take the time to share their knowledge and expertise.
Thank you!
