Missing 1/4sec of audio after transitions

moakes · Post by **moakes** » Sun Jun 25, 2006 9:31 pm

I am using VS9. I have several video clips and am using the same transition to move from one clip to the next. The clips are trimmed perfectly, and the entire project "plays" fine when I preview it in edit mode. HOWEVER, when I burn the project on a DVD and play it, it is missing about 1/4-1/2 sec of audio at the beginning of EACH clip after the transition. Suggestions?

Two points: Are you rendering to one file prior to burning to DVD or are you burning from the timeline? If you're rendering ( correct procedure), then does your project play the audio correctly after the render? I suspect it won't, because I think what's happening is that you're not allowing any frames on your 'in' edit point in order for VS to create the effect. Bear in mind that if you choose say 30 frames for an effect duration, then as your outgoing and incoming pictures are being seen on each half of the effect, Video Studio will effectively take 15 frames from the outgoing file and 15 frames from the incoming file in order to create the effect. If you have given VS an inpoint which is either the first frame of the incoming file or an insufficient number of frames into the new file then VS will do the best it can and produce the result described. The solution to your problem is to loosen the 'in' edit point and to make sure that the inpoint of the new file is at least 20 frames in.

#1. I am rendering from the time line. But you say the other method is the "correct method". Is there a doc of recommended procedures???

#2. Thanks for that suggestion. I was thinking of that. Although most of these are interview type clips and I am just capturing sentences, so the in/out points are tight.

Thanks for your suggestions.

Yes, the top "sticky post" on this form.

Thanks! That is a great doc. Sorry I wrote before I read that, that clears things up.

HOWEVER, it did not solve my problem. When I create a MPEG of my project (per the suggested procedure), and go review the MPEG in Media Player it has the same problem (the first 1/4-1/2 sec of audio for each clip is missing). SO, the problem is occuring before the burning process. Again, it plays fine when I play the project in the Timeline. Any other suggestions.

What is the source of the files you are editing?
What are their properties?

A way around this is to make a frame accurate audio recording of your entire project with all the transitions included, and then render your project as you normally would. Now clear your timeline and enter that rendered file in your timeline on its own; mute the sound on that file and enter your recorded audio file onto one of the audio tracks. This will give you what you're looking for and you can either go down one generation by rendering your muted video file combined with the new audio track, or go against procedure and burn from the timeline.

Slight variation to what TDK1044 suggests and avoids the second render.

1. Prepare everything - cuts, transitions, titles etc.
2. Export the soundtrack.
3. Make any required adjustments in an audio editor of your choice such as Audacity.
4. Mute the soundtrack.
5. Import the edited soundtrack.
6. Now render.

Update. I did try using a different transition and that did NOT solve the problem. The I tried deleting the transitions and rendering and that DID solve the problem.

Thanks for the suggestions. I'm going to try one other test before I go with your suggestions. The video clips are small 5-60sec clips (trimmed portions) out of one large (45min) mpeg file. I am going to render each of those clips into individual files then use the entire files, instead of the trimmed clip which points to the larger mpeg. Make sense? I'll report back.

Your original file is an MPEG? You can try editing it with Womble ($100 - $140 after 30-day trial). It's a special-purpose MPEG editor, and by default it crossfades during transitions, but you can adjust the way the two audio tracks are mixed.
