Overlay track goes black and pauses main track video

[MacWomble]

Hi,

I have experienced an odd development about 75% of the way through a project that, to date, has given no problems at all.

I am mixing together three different videos of the same event, and in order to keep each of the three videos in synch, I have used overlay track 1 and 2 for 2 of the feeds, and the main video. This allows me to cut all three at the same point and rearrange as I need, while maintaining the synchronisation of all three (using ripple editing)

This so far has been amazingly simple and straightforward, and editing has been really fast.

however, I have hit a very odd situation now - the video in overlay 2 suddenly blacks out. This causes the other two feeds to freeze, bt has no ill effect on my audio stream. If I remove the offending feed (an HD video camera feed) then the project preview works normally. I can view the HD video feed with no problem when I preview it in the library - so I know that the waulity of the feed is not a problem. The freeze also happens at exactly the same point each time - even if I remove and then readd the HD feed.

Is there a possible solution for this?

many thanks
Mike

WHat are your two other video file types?
What happens if you cut out the offending piece - where it stops and edit from that point onwards?
If it works ok, there is a possible fault in the data on that video, which could be in the meta data rather than the video data as you say it plays ok to view.

If it doesn't, it may be that you have reached a critical overload point.
Save your project as is and call it something like master.
Save your project as project 1.
Save your project as project 2.
You have 3 identical projects at the moment.

Open P1, cut it at a convenient point before the trouble starts, remove everything after this point, save your movie once you are happy with the edit.

Open P2, cut it at the same point as P1, but remove all of the video before the cut point, then hopefully you can carry on editing as before.

In your specs What size is your processor?

Thanks for your reply - I think you may be on to something with regard the overflow, as it certainly has that "feel" about it.

If I cut the offending piece then I am able to edit the remaining two segments - both of which are from a DV digital camera.

Sorry about not showing my specs - I have a Intel® Core™2 Quad Q8300 2.50GHz processor.

I will try the recommendation to split the project into two

Many thanks!

Hi Mike

Right click each video type and select properties. What are they?
You indicate some as DV, do you mean from a Mini-DV camera. (DV-Avi)

If you are using HD (High Definition) make sure Smart Proxy is turned on and that proxy files have been created.

What are you trying to make?
I assume a standard DVD, if yes, then you may be best to convert the HD video to either DV or Mpeg2.
Using the new file to edit in the main project.

And.............

What version of Video Studio are you using?

I found a work around, but don't fully understand what the problem was.

I went back to my project and found that in fact the HD video stream was in some way the culprit. Even on it's own it would not work beyond a particular point - and it may have simply been the length and complexity of the file.

The work around I found was to export it in a shortened form to a different file format, and use that file in my project.

Thank you all for your help!
