How to Sync Audio and Video

Hi!

I am a newbie using Camtasia Studio 8.6.0 running under Windows 7 Pro (64 bit).

I am trying to create a trailer for YouTube. I have 7 images. For images 1 and 2, I have two separate voice clips (MP3 files created with Audacity). For images 3, 4, and 5, I have one music clip (MP3 file downloaded from the YT Audio Library). For image 6, I ave a voice clip (MP3 file also created with Audacity). And, for slide 7, I have no sound clip.

The images and the sound clips are on separate tracks.

The duration for images 1 and 2 is 10 seconds each but the duration for voice clips 1 and 2 is only 5 seconds each.

What do I do so that voice clip 2 starts after 10 seconds? That is, starts at the same time as image 2 starts?

Thank you!

Hi, Doctor T. I may not understand the question properly. I’m presuming voice clip 1 and 2 are separate .mp3 files. If so, you’d simply drag the beginning of voice clip 2 to the :10 position on the timeline. It should snap to the start of image 2. Am I missing something?

Hello,

Unless I'm missing something, it sounds as simple as dragging voice clip 2 to start (on track above and below) where image 2 starts on your project timeline. Repeat that to get your assets in place timing-wise.

We all had the same thought at roughly the same moment!

John Hazelwood VVV has a more comprehensive answer. I’ll give him the WIN.

line them up accordingly on the timeline; put images and audio clips on different tracks

Hi, Docter T.   

In Camtasia everything has its own space on the timeline. 

I'd suggest making two tracks - one for video(images) and one for audio.  Bring in the images, one-by-one onto the video track, and make them each their desired length. 

Then bring the voice clips in, and place them on the audio track.  If voice clips 1 and 2, say, are in one file, you can either cut it into two; or drag two of the same clip onto the track, and shorten each so that they only include the respective clip.  Then move the audio clips to the desired place on the timeline underneath or on top of their image.



I hope this helps.

Hi!

Thank you all for your prompt replies.

Yes, it was very simple to do but I just didn't know how to do it.  That's why the call us newbies. :-)

Is there a way to have fine control over moving tracks on the timeline - more precise than clicking and dragging with whatever default timeline "snapping" is set (i.e. frame-by-frame, or small enough interval to really sync audio with video?

Actually, I think my video and audio tracks are in sync on timeline, but during playback only, the video track leads the audio playback. When I line up the play head on the tracks, video and audio are synced, but during playback, they are out of sync. I am guessing this has something to do with settings and/or computer resources.

I am running Win 10 Pro with an i-7 (eight cores) running at 3GHz, and I have 16GM RAM. I have a lot of computing resources, but only an on-board GPU, rather than a discrete video card with dedicated GPU.

Anybody have ideas about both of the above issues, since I am still interesting in fine control of shift tracks, but main problem may be graphics processing with a powerful Main CPU with on-board Intel HD Graphics adapter - but, not external graphics accelerator card.

Thanks,
Jeff

Hi Jeff,

It's been 8 months, so hopefully you aren't still having this problem; but for those who come next...  :-)

First, the hardware question:  your system resources are fine.  Video editing (particularly the rendering) rely heavily on the processor.  It is a natural assumption to think that since video cards are used to handle the heavy visuals of gaming, they must also be used to handle the heavy computing load required to render video.  Actually, this isn't so.  Processors and RAM are the workhorses of video editing.

On the snapping issue:  both canvas and playhead snapping can be disabled in the "View" menu.  Disabling these will allow you much more precise control.  Alternatively, if you keep canvas snapping enabled, you can split the affected tracks, each at the exact point that you want them to align.  You can then snap that point to the same place on the canvas.

And TechSmith, if you're monitoring, please add an auto synchronize audio feature!

Cheers!

Thanks for the feedback tomtrom77. I have leaved a lot in the past 8 months, regarding computing resources for video editing, and I have shifted to Adobe Premiere Pro as my primary video editing tool.

I use Camtasia for screen recordings, since so easy to add transitions, animations, and zoom, pan, and cursor effects. Thanks for the tip on snapping. I think I had it turned off, but was wondering if there are keystrokes that can nudge clips on tracks frame-by-frame, if I recall. Otherwise, I presume I just can zoom in on the timeline and click and drag clips one frame at a time. Any tips there?

Camtasia's chroma key functionality is really too primitive for serious green screen work. That was that main impetus to seeking out Premiere Pro.

On the delayed playback between video and audio tracks, I believe it was related to my processing power. I still need to upgrade to a good laptop or desktop for video editing, as soon as I am ready to spend $2-3K on PC upgrades.... been spending a lot, but on video gear for production, rather than PC gear for post-production.

Thanks again,
Jeff
