To save time, let em free run. You can then sync each camera one time on different tracks and go through subtractivly, as if switching a live show. This keeps ya from finding sync without matching time code per shot. </p> http://www.videomaker.com/community/forums/topic/syncing-audio-from-multiple-cameras#post-50641 Sun, 06 Sep 2009 20:38:04 +0000 nccgeorges 50641@http://www.videomaker.com/community/forums/ <p>Hi EarlC,</p> <p>When you do live recording and you get all those live inputs, individual lines to your board, camera inputs from your cameras and all those H2 recorders. </p> <p>With all those recorded inputs, when you mix down the video and audio with something like FinalCut how do sync the audio from all those source that they all sync up in post production. I would guess you blend the inputs to what sounds best. </p> http://www.videomaker.com/community/forums/topic/syncing-audio-from-multiple-cameras#post-45628 Wed, 08 Apr 2009 12:26:34 +0000 czvp 45628@http://www.videomaker.com/community/forums/ <p>here's a link to the same exact camera i use. can you tell me how i would it up to a bands mixer??? it says no mic jack or headphones jack in the specifications. <a href="http://www.bhphotovideo.com/bnh/controller/home?O=NavBar&amp;A=getItemDetail&amp;Q=&amp;sku=800614152&amp;is=USE&amp;si=acc&amp;showAll=1#specifications">http://www.bhphotovideo.com/bnh/controller/home?O=NavBar&amp;A=getItemDetail&amp;Q=&amp;sku=800614152&amp;is=USE&amp;si=acc&amp;showAll=1#specifications</a></p> http://www.videomaker.com/community/forums/topic/syncing-audio-from-multiple-cameras#post-45547 Sun, 05 Apr 2009 15:10:22 +0000 M-323 45547@http://www.videomaker.com/community/forums/ <p>well, you could wire one camera (usually the closest) right into the band's sound mixer. this gives you the best audio, using their audio equipment.</p> <p>if your subject doesn't have it, you can either a) use a boomed mike or b) wireless mic but they seem to pick up interference - especially if you are near lighting, or audio equipment etc. boomed Mic is best if you cant steal their audio.</p> <p>then you can use the pics from all the cameras and only one audio.</p> <p>... one time I tried a big ear mic -- one of those parabolic mics for a sporting event. it worked pretty good cause the crowd was behind me, I was able to focus on audio from the game. the little ambient sound from the fans was just enough. I had though that if it blocked out the fans entirely, I was going to fake the ambient sound with a crowd track in post but I didn't have to.</p> <p>best, Phil</p> <p><a href="http://www.WiseGuyProductions.ca" rel="nofollow">http://www.WiseGuyProductions.ca</a> </p> http://www.videomaker.com/community/forums/topic/syncing-audio-from-multiple-cameras#post-45527 Sat, 04 Apr 2009 13:19:49 +0000 EarlC 45527@http://www.videomaker.com/community/forums/ <p>I have produced MANY lip synced music videos over the years, as well as LIVE productions, using multiple cameras.</p> <p>When producing for independent artists in a controlled environment - their home, home studio, garage, or a rented storage facility stacked with their amps and equipment, where they can "practice" and play til their hearts content without the neighbors yelping about noise to the local PD. This is where you have a choice between and/or lip syncing to a recorded piece(s) they are happy with, or live - either way with repeated performances.</p> <p>When my groups have been intimately familiar with and solidly attuned to their CDs, and have recorded "live" at reduced volume, but actually syncing to the CD playing at high volume, and have been willing to spend the time doing one, two or several takes for each selection, success is wonderful. There will always be times when the lips and CD music track are not SPOT ON, but close enough that if I have also captured some other stuff - cutaways, alternate shots that do not focus on the lips, hands on keyboards and guitars, etc. side shots, or distance shots, I have been able to hide the second here or there where I cannot get a match.</p> <p>Also, I have had occasions where their live performances actually came out sounding better, and working better, than with their efforts to sync to the audio CD.</p> <p>I will NEVER again trust the buy on the boards, the mixer, the house sound - too many times have had to have my systems and cameras audio circuitry repaired due to blown out circuits because this supposedly experienced audio person hits the wrong levels at the wrong time. So, I use on camera mics, with additional and occasional direct feed mics focused on the amp sweet spots and feeding into a board of my own and into an auxiliary wide-shot camera mostly used for direct feed from MY audio mixer. Also, I use a host of Zoom H2 digital recorders placed where I think they are needed.</p> <p>I have stacked these audio tracks, used them independently, or only one or the other, depending on what I and the talent deems best quality. It takes a LOT of work, but the redundancy of audio acquisition and ways of acquisition is the secret to having enough choices to make SOMETHING work.</p> <p>My suggestion is to first and foremost try to get several take of the group performing to their prefered CD or other digital sound source via lip sync. From there, I go with the other possibilities I have outlined.</p> http://www.videomaker.com/community/forums/topic/syncing-audio-from-multiple-cameras#post-45526 Sat, 04 Apr 2009 10:59:54 +0000 czvp 45526@http://www.videomaker.com/community/forums/ <p>no ive actually been to guitar center since and spoke with some people who do it. they said because the band wants to have the actual live sound i should connect all the mics to a physical audio mixer or an external sound card with an audio mixer program for the computer. shoot the video with two cameras them edit it and sync the mouth movements from the two cameras. that would be the cheapest longest way to go being that im low on cash. the easiest fastest most expensive way would be buy a video switcher which everything hooks up to and you can just fade from camera to camera so you dont have to do much editing to the video when its finished. ive decided to buy the external sound card with the audio mixer software and use my computer as my mixer for the audio and im going to try my best to sync the mouth movements lol but it will sound live. after a couple jobs i plan on getting a video mixer. thanks for everyones help! even all the people who wrote me on windows live, myspace, and emailed me </p> http://www.videomaker.com/community/forums/topic/syncing-audio-from-multiple-cameras#post-45504 Fri, 03 Apr 2009 07:02:58 +0000 CraftersOfLight 45504@http://www.videomaker.com/community/forums/ <p>From what I have seen, if you are going to do many shots of the band members, you might want to think about doing the following. Most "studio" shoots play the song being recorded in the background and the group plays along or "airbands" it. this allows them to keep the same tempo/sync as the music they will be using in post. (I would not count on things going well enough that you could do it all in one take). They will do many takes with the cameras at different angles on different members of the group. Then in post they would cut the scenes to the same recording they were playing with as the sound track. This allows the lip sync and play sync to line up.</p> http://www.videomaker.com/community/forums/topic/syncing-audio-from-multiple-cameras#post-45502 Thu, 02 Apr 2009 22:33:23 +0000 czvp 45502@http://www.videomaker.com/community/forums/ <p>well im not videoing a live show in an auditorium or anything. it will be in his living room most likely. can i use audio mixer software for my laptop or do i have to actually buy an audio mixer?</p> http://www.videomaker.com/community/forums/topic/syncing-audio-from-multiple-cameras#post-45391 Mon, 30 Mar 2009 19:51:05 +0000 czvp 45391@http://www.videomaker.com/community/forums/ <p>hey im a wedding videographer but ive been asked to do something a little out of my league. i shoot with 3 cameras at weddings but the audio isnt important so i put music tracks through the entire video. well some friends ask me to shoot live footage of them singing with multiple cameras but i do not know how to get the best audio quality. i ran across this perfect example of the kind of video they want on youtube. ill post a link in this post. my question is can you tell me what they are using in this video to get the great live audio. i can do the same exact thing for my friend putting a recorded track he has over it and just sync his lip movements to the audio.</p> <p><a href="http://www.youtube.com/profile?user=boyceavenue&amp;view=videos&amp;start=20">http://www.youtube.com/profile?user=boyceavenue&amp;view=videos&amp;start=20</a></p> http://www.videomaker.com/community/forums/topic/syncing-issues#post-39931 Sat, 06 Sep 2008 19:15:24 +0000 larrymills 39931@http://www.videomaker.com/community/forums/ <p>  Audio not synched with video upon export in Ultra cs3 or Ultra 2 ???</p> <p>Audio and video out of synchronization - solved, but would like some help!</p> <p>On my laptop the audio and video are out of synchronization, but not on my laptop.<br /> So for my laptop, here is what I did, as I cannot figure out my wrong settings on my laptop.</p> <p>(1) Export only the video portion in Premiere to Ultra, and then bring back this �video after ultra� into premiere, and use with the original audio track.<br /> (2) For those who cannot follow this, there is a second way to achieve the same results, but a little more cumbersome:<br /> Keep the �before ultra� audio on Premiere.

video back into perfect synch.  Once you've corrected the error in the NLE, render that file &amp; check out the lip synch of the rendered file.  If the rendered file is in synch, we can rule out the NLE as a source for the problem.</p> <p>Right now we need to test each of the elements of your production process individually to locate where the synch problem originates.  Or if it is something that just gets more pronounced at each step of the production chain.  Once we locate the step causing the problem, it will be easy to fix it.  Trouble shooting is always the hardest part for most folks.  Once you can answer each of the questions, we can take that simple step to fix the problem.  Or in the worst case, I can teach you a "work around" that doesn't fix the problem but will still create a video in perfect lip synch.</p> http://www.videomaker.com/community/forums/topic/syncing-issues#post-36875 Tue, 27 May 2008 04:19:17 +0000 drhyne 36875@http://www.videomaker.com/community/forums/ <p>Sorry for the delay in responding.  I was out of town.</p> <p> Originally I thought it was just when rendering to wmv.  But I have also discovered that it also happens coming out of Ultra as an AVI too.</p> <p> I'm self taught so bear with me.  But when I save, I always use the default settings first.  I have experimented making adjustments to them, but no luck.  I've research codecs, aspect ratio, etc.  So I've played with these.  But I still seem to have the issue.</p> <p>Could it be the default codec settings on one program are different than another, so what I'm doing is resaving in different codecs, etc.?  Also, most wmv saves result in a very poor quality.</p> <p> I've tried the programs I'm using for saving and I've also tried Windows Media Encoder.  I've also tried taking the final avi into other programs for the final wmv save, like Windows Movie Maker or back to Visual Communicator.</p> <p>Could the problem be the camera settings in the original filming?  Or filming straight to the computer rather than a DV disc?  I'm so totally frustrated.  I know there is probably an easy solution, I'm just not versed enough to figure this out. </p> http://www.videomaker.com/community/forums/topic/syncing-issues#post-36718 Fri, 23 May 2008 10:46:26 +0000 BarefootMedia 36718@http://www.videomaker.com/community/forums/ <p>I'm assuming that your AVI files are all perfectly synched.  So the problem develops during the rendering to WMV process.  I can't see how your audio or video card would have any influence on playback (except on your computer.)  The cards are only for output (you don't capture by running AV signals into the cards.)  I'm guessing you are importing via a Firewire input when you use Visual Communicator.  The cards are not used anywhere in the recording &amp; rendering process.  So I'll also assume the synch problem happens on everyone's computers.</p> <p>So you need troubleshooting to discover the problem source.  Does it occur when you render to AVI, transfer to disc and play on another computer?  Or is it only happening with the WMV files?  It sounds like you render directly into a WMV file, so what happens if you render to AVI then use one of the many free video conversion utilities to convert the AVI to WMV?</p> <p>But this problem really sounds like a software issue in Premiere Pro.  Are you positive you've got the most recent codecs in place?  Are you using default settings for rendering the WMV file?  What happens when you customize the WMV settings?  Do some troubleshooting and get back to us with the results.</p> <p>This is not a normal situation, but some troubleshooting will be able to locate where the synch issue begins.  Then we can solve it.</p> http://www.videomaker.com/community/forums/topic/syncing-issues#post-36715 Fri, 23 May 2008 10:05:04 +0000 drhyne 36715@http://www.videomaker.com/community/forums/ <p>I capture in Visual Communicator, save as AVI and key green in Ultra.  Both formerly Serious Magic recently aquired by Adobe.  I then edit in Premiere Pro.  Ultra is far superior to Premiere when keying.  I always save files as AVI until final save down to put on CD/DVD.  I have to use a universal format for all our clients.  WMV seems to be the one everyone can access.  I can take a final video that isn't syncing, decrease the size of the viewing window, and the video will sync pretty well.  That's another reason I'm thinking it has to do with processing speeds.</p> http://www.videomaker.com/community/forums/topic/syncing-issues#post-36713 Fri, 23 May 2008 09:53:54 +0000 Johnboy 36713@http://www.videomaker.com/community/forums/ <p>what software are you using?</p> http://www.videomaker.com/community/forums/topic/syncing-issues#post-36712 Fri, 23 May 2008 09:39:59 +0000 drhyne 36712@http://www.videomaker.com/community/forums/ <p>I'm having issues with audio/video syncing.  It can be off or on at any point in editing.  The final save for DVD or CD is a video that looks like the talent's voice is being dubbed in another language.  It appears the audio and video are processing at different speeds (?).  A friend offered the suggestion that my video and audio cards might be the problem.  I currently work with 2 PCs. The first is a Dell XPS 720 desktop w/Intel Core 2 Quad CPU; 2.40 GHz; 2.75 RAM; NVIDIA GeForce 8800 GTX (2); and Creative SB X-Fi sound card.  The second is a Dell XPS M2010 Laptop with a Intel Core 2 CPU; 2.00 GHz; 3.25 GB Ram; ATI mobility Radeon X1800 video card; and a Sigma Tel High Definition Audio card.  Both are running on Windows XP.  Does anyone have any suggestions that will help me get my syncing issue resolved.  Thanks!
