Video syncing issues

I'm new to the video ipod and am having two problems with the video transfers. First, I have tried 'importing' and 'finding file' from my harddrive to bring to iTunes, and it won't let me. These are .avi files, and I am aware I will need to format to fit the iPod once they arrive in iTunes. Secondly, I have synced a couple of television shows to my iPod, but lost the sound along the way. I have picture, but no sound. Any suggestions, ideas, tutorials are appreciated. Thank you.

Why Wont Apple Fix AUDIO / VIDEO Sync Issues

This has been a problem for awhile. Thank god there is a application fix but im receiving an iTouch very soon and I'm not sure if the same problem is going to be on that to..
It might be how Quicktime reads .MP4 and .M4V Files but i can play the videos on VLC and Zune Software fine..
I see other people posting this exact same problems. I see no answers... Apple Knows this is an issue. Why wont they fix it.
From what im hearing it is the audio that is going out of sync from the video.
Now my Final Question is
"Is this just a Software issue for the computers or is it also a Software issue (Assuming that quicktime is the software on these devices) for the iTouch / iPhone ?

well i got my itouch today and it seems that the audio and video sync issues are only on the computer distributions of quicktime and not the hand held device versions

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.

Audio / video sync issue in playback

for every recording i've made, when i play back the archive there is noticable lack of sync between the audio and the person's mouth. the video seems to lag behind by almost a second. the good news at least is that the delta is constant.
has anyone else experienced this? it's happening in any scendario i try, even if i'm just recording myself.
is the LCCS dev team aware of this? since audio and video streams are recorded separately, is there any way for me to programatically 'nudge' the streams into sync?
it's currently a show stopper, it looks really bad when the sync is so obviously absent.

finally getting back to this..
i did as you suggested and recorded a video of myself using the recording and playback examples provided with the SDK (the 2.2 newest version btw).
the de-syncing of audio and video is definitely there. it seems especially bad for longer recordings. however, an interesting thing i discovered in playback:
- sometimes, if i drag the playhead somewhere in the recording, pause, and then hit play, video and audio fall into sync.
- if i start playback from the beginning of the recording, audio/video is always out of sync.
i understand that the video and audio streams are recorded separately and thus played back separately. my guess is that when those streams are retrieved and playback begins, one starts before/after the other because they're not retrieved at exactly the same time. it seems some extra work is required to ensure that their playback commences at exactly the same timestamp within each stream.
i can provide my recordings as an example if required.
this is a total showstopper for me. it renders the entire recording service useless if the playback can't have sync between audio and video. i would be happy to help with testing this more. can someone from the LCCS team comment on this issue?
thanks

Strange audi sync problem & different, stranger video sync issu in sequence

I have two strange occurances with one particular set of media that was downloaded from the same original source mini-dv (recording in dvcam) tape. I have not found the same issue on any other footage.
1) when the media is imported into FCP, the audio is out of sync. it is slightly out at the beginning and then gets progressively worse.
2) when this footage is used in a sequence, the video that show in the sequence is not the same as the video that is exported when this sequence is exported as QT movie (or any other export option) Like the audio the video out of sync gets progressively worse.
- The original media is perfectly in sync looking at the digitized source ie: in Quicktime. There is no audio out of sync problem.
- the only difference I could see in the file was that this media is 3.5mb data rate whereas all the others are 3.6mb.
- other tapes from the same camera do not have a problem
- I do all my downloading from a firewire deck and not from the camera
- I upgraded from 6.0.1 to 6.0.4 (as did the QT 7.5 upgrade also) to see if that fixed the problem but to no avail.
Very perplexing. I managed to work around this problem in a sequence whos deadline was looming by manually slipping the footage in the sequence the required number of frames. This is where it also gets odd. I was able to do this by
- double click the clip in the sequence which then loaded that into the viewer.
- position the playhead at the beginning of the clip
- from the canvas select the go to position in master clip option which then loaded the masterclip into the viewer. the position in the masterclip was always the correct frame (ie the frame I expected to see as per my edit). The frame showing in the canvas was also the correct frame (but this would not be the case when exported)
- the next thing i did was to use the slip tool, as soon as i held the slip tool over the sequence clip, the frame in the canvas would be the wrong frame (the frame i would see when I exported).
- then i would just carefully slip the sequence clip back to the matching correct frame. So watching in the viewer, I would align the frame that showed in the viewer to the frame in the canvas.
When done the frame showing in my sequence would be a completely different frame but when exported, the frame that I expected to see would be the exported frame.
I could find no logic to the amount I needed to slip each time (I am sure there is logic but I couldnt figure out what that was). the clip at the end of the footage needed to be slipped -10:09, and this got progressively smaller to the clip at the beginning of footage needing to be slipped -:16
Hopefully that wasnt too confusing.

btw, i have tried recapturing the footage and i have offlined it, copied it to another location and onlined it in the new location to no avail. still have the sync and video in sequence issues.

10.5.3 and parallels video sync issues

My video in my virtual XP now gets all fuzzy and chops in and out, until I reset the window size (by dragging or using the contoll panel and changing the size 1280x1024, etc, etc). The screen calms down, but eventually because of moving in/out of the virt to the osx side, the video takes a hit and starts buzzing and individual elements of the windows gui (for instance, the start bar only) start flashing in and out. Again, until I force a screen re-sync by changing the size. I own fusion and parallels and am in the process of migrating my parallels to fusion via the convertor tool. Too much set up in the my xp to just try re-starting. I did however, for testing, create a NEW parallels virt, and install a fresh XP into it, SAME issue with the video, so then I did a linux, SAME issue.
10.5.3 has jacked up the video within parallels, I have checked both sites and not found mention of this yet, so here I am.
For reference, I run all my virts in windowed mode, not full screen.
Anyone have any info? Thanks.
SD

I know this is a pain in the butt, but I had to use my Virt to get work done, and cant waste the time to reboot, reboot, etc, etc.
Heres a temp fix, possibly a full time one for you all, Download the Demo of VMWARE's Fusion (vmware has been around 10 times longer than Parallels), and you can test it for a month free (possibly Parallels will have a fix by then), they also have a Fusion Migrator tool, its also free, so I downloaded fusion with a test key, and the convertor, ran it, it converted my parallels to a fusion vert (leaving my parallels alone until they can release a fix) and made a duplicate of it (disk space is the only requirement) that loads in fusion.
Now I enjoy some of the features parallels uses, mostly the mapping of my windows My Documents to my Mac Documents, something fusion doesn't do, but can manually be done.
BUT to my surprise, fusion has 3d graphic support, as well as dual core emulation for the virt (which means you can turn it off, make it use 1 core) and get a better equal virt / OSX performance.
I hate to sound like a sales person, but if you need to work today, heres a free solution, I might just stay with fusion since I can play games I had to previously boot camp to use.
Lets hope a fix comes out, but its been nice to know about the graphics. I just created a small 5 gig xp install, for gaming only, running it on firewire 800 disk space, and I CANT BELIEVE the performance while being hosted from firewire, no lag that I thought the I/O would have running from a external disk.
Anyways, hope that helps. When I find a fix for parallels I will post it, I tried rolling back 1 update on Parallels and it didn't fix it, unfortunately they don't let you download old revisions, maybe someone might have something older than 5584 cause it still is affected as well, 5584 and 5600 both are crippled by 10.5.3.
Sad thing is what does apple care that it made XP break on it. I hope they do care and attempt to help.

IOS4 on 3GS and Photo / Video syncing issues. TRY THIS

THIS FIX IS ONLY ANY GOOD IF YOU ARE WILLING TO TRASH ANY CAPTURED VIDEO ON YOUR IPHONE
iOS4 only.
Yep, the same as a lot of people here I am having no end of problems syncing photo's and video from my iPhone 3GS running iOS4.
I get the same black boxes and stuff. iPhoto hangs on import.
Tried image capture. Told me it was syncing 47 items out of the 47 items in my photo folder on the iphone, only 16 items copied across.
iPhoto or image capture not deleting the files after import.
After much deliberation and mucking around I have found it's the video's that were causing the problem. Luckily for me the video's on my iPhone were not important so I deleted them from the phone. Re connected to iPhoto, synced and deleted originals after import - hey presto it worked. Only issue remaining was the black boxes in the photo library on the iPhone. A quick re sync of the photo's tab in iTunes and viola - everything A OK.
Problem is I now know it's an issue with the video files and iPhoto since iOS4 update. Video was working fine before iOS4
Come on Apple - sort this bug out.

Open the iPhoto or Image Capture preferences and set them not to open when a camera is connected to the computer.

Audio/Video sync issues after exporting

Two quick issues:
1. I've recently exported a project from FCE4 to quicktime and am finding that the audio is slightly out of sync with the video everytime.
Is there an ideal format or setting I need to export at to avoid this?
2. Also, I've edited two projects using the same clips and keep finding that the second one I make seems to make the video very narrow when I export it. Is there a setting I need to use to avoid this, or does the problem lay in the setup?
Cheers!
John

From what I see in your info, the clips don't match the Sequeunce.
Furthermore, the clips are not FCE freindly. Probably required rendering?
I'd suggest using Streamclip to convert the H.264 clips to the exact specs of one of the FCE>Easy Setups, audio and video properties, then start over.
http://www.squared5.com/
BTW: Whatever you convert the clips to must match the Easy Setup, so that you work with Clips and Sequence being the same. The best way to acheive this is to start a NEW Project, set the Easy Setup first, then bring in the the matching clips.
Using Item Properties in Browser>Seqeunce/Clip is one way to confirm matching specs for both.

Video Sync Issue, a tough one to solve. Good Luck!

Hello all,
This is a big one. Props to anyone that can tackle this.
I'm going to lay out our specs, then our issue.
SPECS
Writing Computer (master):
Dual 2.5 G5, 2.5 gb RAM, running Logic Pro 7.2, Tiger OS 10.4.5
Motu 24 i/o (2 of them)
Unitor8 Midi Interface
Big Ben Clocking
Maxtor 7200 RPM 300gb firewire 400 external drives (2)
Video Computer (slave):
Dual 1.25 G4, 2 gb RAM, running Pro Tools LE 6.9, Panther OS 10.3.9, Quicktime Version 7.0.4
Digi 002
Maxtor 7200 RPM 300gb firewire 400 external drive (with PT sessions and Quicktime Videos on it)
Aurora Fuse-X Video Card running S-Video out to a TV (to view picture on a larger screen)
ISSUE
Logic sends Midi Machine Control and Midi Time Code to the Pro Tools Digi 002, so that a Logic session with specific time code will play the video in the appropriate location on the Pro Tools computer. We've tried this two ways. Directly out of the Unitor8 into the Digi 002's Midi In Port. Then we tried going out of the Unitor8 and into a Midi Sport 2x2, then USB from the Midi Sport into the Video Computer. The Midi Sport way offered a bit of help, but not much.
Here's what happens:
After putting the session for any given reel of video into "Sync", video will lock with Logic for about 4 or 5 passes. Then video in Pro Tools will start to stutter, not lock up right away. It gets progressively worse. The stuttering eventually turns to non-compliance with Logic all together. When the stuttering begins, the "Sync", "Play", and "Stop" buttons flash intermittently, blue, then gray, then blue. It's as if it's being sent Midi information to play, go into sync, and stop, all at the same time.
Strangely, if we close the session, reopen it, put it in to sync, and move the playbar in Logic and play from Logic, it will work again, for about 4 or 5 passes.
Very frustrating.
We run a similar system in the next room. The writing computer is the same, but the Pro Tools Video computer runs a TDM system on the exact same dual 1.25 G4. On the TDM system, the video runs perfectly. Always in sync, never stuttering.
What causes this issue on the LE system? I don't think DV Toolkit would help, but we've thought about it. Someone else suggested an Avid Mojo. Is there any way to make this setup work with the equipment we currently have? Changing the video type maybe?
We normally use/request Motion J-PEG A files.
Is there a preference I'm missing somewhere? Something I'm overlooking?
Any help is GREATLY appreciated. Thanks in advance!
Sincerely,

Hey Shwartz,
We run video on a separate computer with Pro Tools for a few reasons. One of them being it takes some of the processing load off of Logic, inducing less problems within the program for us. Another reason is that we can record demos directly into Pro Tools with video, so that we can screen them for clients all from the Pro Tools rig. Good for Pre Records too, many reasons.
To answer your questions...
1. It is the Pro Tools transport that is stuttering. Logic runs fine. The Pro Tools rig stutters and does the blue gray thing. The Pro Tools rig is receiving Midi Machine Control and Midi Time Code.
2. In Logic/Prefs/Midi/Sync under "Transmit Locate Commands When..."
"Pressing Stop Twice" is checked
"Dragging Objects" is checked
"Transmit Record Enable Commands For Audio Tracks" is NOT checked
3. I'll see if I can make this work, but they are quite a distance appart (through some sound booths etc...). I don't think it's the Logic computer, but it's worth a shot!
The only variable I see different is an LE Rig compared to a TDM Rig.
I'll let you know if I can find a gigantor midi cable to test it.
Any other ideas?

Video Sync Issues

I have two questions about videos and iTunes. Apologies if these things have been covered here. I searched for relevant posts but didn't find any.
1) I downloaded a series of iTunes U videos, then synced them to my iPod touch. I watched a number of them on the iPod touch but didn't delete any of them. When I synced the iPod touch via USB, the watched videos disappeared from it, although I suspect that they're still on iTunes. (I'm away from my Mac at the moment, so I can't verify this.) What happened? Is this normal behavior? Is there any way to control it?
2) I transferred some TV shows from my TiVo box to my Mac, then used Toast to convert them for the iPad. I noticed that when the conversion for each show was complete and imported into iTunes, iTunes would start to play that show. I then synced with the iPad. However, then I went to watch the shows on the iPad, not all the shows were there. I suspect that any show that played to completion in iTunes after its conversion wasn't copied to the iPad. Could this be the case? If so, is there any way to prevent either the lack of sync or the playing on import? I plan to pursue the playing issue with the Toast people, but perhaps someone here can help.
Thanks for any enlightenment.

The default sync selection for TV shows is to sync all unwatched episodes of all shows and for iTunes U is to sync all unplayed of all collections. So, unless you selected another option it's normal for those episodes you watched to be erased on a sync.
The other sync choices for TV shows include all episodes of all (or selected) shows, or the newest 1, 3, 5, or 10 episodes, or the newest (or oldest) 1, 3, 5, or 10 episodes. The iTunes U choices are somewhat similar. I think you'll find adequate choices within the drop down sync menus for what you prefer.

Final Cut Audio/Video sync issues

Yes, I realize this has been discussed before, but for the life of me I cannot find the answer. So here we go.
- FC version is 7.0.2
- OSX is 10.6.3
- Processor 2.8 Ghz Intel Core Duo 2
- Memory 4 GB 800 MHz DDR2 SDRAM
I have used FC before and well acquainted. Recently I took a brush up course and used material provided in a book DVD. Had no issues while practice editing with this material.
Now have material saved I want to edit with. All video is saved on an external and in MOV format. No worries getting in imported in FC. However, every video I use starts to audio slide and by the time it reaches around halfway, full blown out of sync. Not by much, but it's definitely there.
I even took these videos and re-saved them in MOV format and same thing. With all this RAM there should be no need to shut anything down, but I did so. Same thing.
The interesting part is when using the test videos that were supplied on DVD and were imported into the MAC, no worries. Now I AM bringing those videos over from a saved file on the MAC itself, but that should make no difference. When bringing over the external movies into FC, they should react without a hitch.
Here's the fun part. ALL of these videos play perfectly on IMovie. All of them. So this makes me think there's something in the FC settings at work here. Then again, why did it not fault before?
One more thing. I recently upgraded to Snow Leopard and have seen a few glitchy items here and there. But this is the oddest.
Would really appreciate thoughts and suggestions. Frustration is setting in. And thanks

The first thing I'd check is to make sure the audio clip's settings and the FCP Sequence settings match. For example, if you use AIFF 32khz, 12 bit audio in an FCP Sequence set at AIFF 48khz, 16 bit, the audio WILL be out of sync as you describe.

Audio/video sync issues at chapter points, on certain DVD players

I created a DVD using DVD Studio Pro 4, had it replicated at a manufacturing facility, and have now sent out copies to approximately 600 people. About a dozen or so of my customers have experienced issues where at the chapter points for the film (a 60-minute documentary) the audio and video go out of sync. Unfortunately I can't describe this issue any more accurately than that because I haven't seen the problem. The disc plays fine on the vast majority of players. The people that are experiencing the problem have DVD players like the Sony DVP-NC655P and the Samsung DVD-R120.
Does anyone have any clue at all as to what the issue could be?
Thanks very much.
G5 Dual 2.5 GHz Mac OS X (10.4.10)

Is your audio PCM or AC3? If the audio is going out of sync on onlyl a handful of set-top players, the build is probably OK, and your media is probably starting out in sync. I suspect that your bit rate may be be too high, and the audio is chiking the buffer on the player, making the audio go out of sync. What format of audio is on the disc, and what is combined average/maximum bit rate?
Hope this helps -

Audio / video sync issues

We are using JMF with FOBS4JMF - on some computers our player has an issue with the audio and video getting out of sync with FLV files - any ideas? Is it related to frame rate?
Also, if we capture to a MP4 - the video plays but we do not get any audio - but the same file played in QT plays just fine. Any ideas?

JMF doesn't support MP4 or FLV videos, the support for those are coming from FOBS4JMF, which is a 3rd party add-on to JMF. It's the policy of these Sun forums that 3rd party add-ons and libraries are not supported here.
As such, you'll need to get FOBS4JMF support from the FOBS people.

Audio / Video Syncing Issues

Hello Everyone,
I own a 2011 MacBook Pro with a 250GB SSD and 8GB upgraded Ram. I'm currently using iMovie to create an hour long movie with images / audio / and voiceover in certain sections.
I have been working on this for quite some time and would like to be able to export it the same way I'm able to view it inside the Application. However, when I export the movie the audio / video / voiceover is off and it does not match with what I have worked on inside the project.
I have also tried breaking down the movie and exporting it in sections but the audio is still not syncing correctly on the export.
Please can someone help me out and help me explore my options.
Thanks in Advance,
Mauricio

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?
