VIDEO SYNC TIP THAT WORKED!

Postby Bob Harper » Fri Feb 27, 2015 10:25 am

Hi:

Not sure if this has been posted in the past but knowing the angst
one can experience with video-sync issues, (like me as of yesterday)
I wanted to pass along something I just tried that WORKED!

I created a rather elaborate 2:45 show for a political candidate
that utilized a variety of no-audio, stock video footage along with
3 specific video clips of the candidate talking.

Once everything was completed, I rendered a 720 Quicktime MOV, h264
and lo and behold his audio was racing ahead of the video in all three
locations. I tried a zillion different work-arounds from converting
his video clips to different codecs, types etc., to eliminating other
elements of the show but again, no luck.

I had a million things going on in the show and figured it was just
too much for Producer 6 to handle. For instance, my main music
mixes were on the main audio line and then my voice over track
was on slide one to let play throughout and THEN, a bunch of different
slide sounds on almost EVERY slide. THEN...the idea hit me.

I made three separate cuts of each of his clips' audio tracks and then used each
as SLIDE SOUNDS since I could regulate a slide sound's playback precisely.

Once inserted, I put his video's AUDIO settings to ZERO and adjusted each
slide sound of his voice to sync with his lips and then crossed my
fingers. After the render, I hit play and IT PLAYED BACK PERFECTLY!

SO...with that said, keep in mind that if you run into this issue,
you MIGHT be able to grab the audio of your VIDEO clip and use it as
a SLIDE SOUND! (Just remember to kill all audio on the clip itself)

I hope this saves someone from pulling his or her hair out.
Mine comes out naturally but the effect was certainly there
for more than a few hours. ;-)

GOOD LUCK!

Good tip - one thing you might mention is what utility you used to grab the audio from the video clip (I can do it in my video editor, but others may stumble on how to do that). Your method of a separate audio clip also allows the user to "tweak" the audio if necessary in an audio editor like Audacity etc. (remove clicks, normalize, compress etc.)

Yes, using the audio from a video as a slide sound is a great tip. I sometimes have had to do that, for whatever reason. Say, the sound of the video is too soft and I wanted to make it louder. No, you can't just set the video sound higher; Proshow will cut it back down to 100%.

But you found your sound was in sync. I have found I have to do, say, a negative half second or so offset to make the sound synchronized.

I use the Goldwave audio editor and it will pull in the sound of a Quicktime video just fine--AVI too, I think. That's how I split out the sound.

You may use Audacity which can import some video files format retaining only the audio part. Then you export as audio file.
Another free software : Freemake Video Converter which can export the audio part of a clip.
