Quicktime. The limit sees to be between 20 and 30 seconds of uncompressed HD format.
Any idea?

Yeah, it's a "feature" of the code we're using - it's using the old video for windows avi library, I think it goes weird if a file gets larger than about 2Gig. The answer is to use some compression. See Barry's description of using lossless or motion jpeg.

It should retain the quality - but the file sizes would be much smaller.

We do plan to update the video creation code at some point (by switching to the more up-to-date directshow stuff) but we don't have any timescale for that.

I would also recommend switching to another media player - Quicktime and Windows Media player can struggle with HD content.

I use Media Player Classic:

but VLC Media player is also pretty good:

Take care,

an alternative approach (depending on what the final destination of your movie is) is to record your video in a couple of takes; eg first 30 secs, next 30 secs.
This allows you to keep it uncompressed albeit split up.
You can then use videojoiner to join up and compress to the output format you require (XVID for Youtube for example)

That helped a lot, tnx. Guess I have to install the codec pack and then have more
options to compress. Hope that will work on Win7 as well.

Tnx, Good idea, but unfortunately I cannot split the recording in different takes.

In HD it would play very jerky.
Oh well, I thought it was my computer that was on the blink!!

Barry's machine is Windows 7 - so it should be fine.
