It's working as designed. See note #3 at the bottom of the page:
"/ *3 / - Motion pictures can be recorded continuously for up to 29 minutes 59 seconds in European PAL areas. Also, motion picture recorded continuously in [MP4] is up to 4 GB."
This is due to an EU VAT issue--anything that can record continuously for 30 minutes is taxed as a video camera.
So you have to hit the record button every 29:59 and yes, this will cause a gap in the video.
And yes, it's inconvenient - Mark
MY tz25 camara cuts out after 30 mins video. is there any way of altering this.?
When i bought it, it said there was an hour of video but its default is to go to sleep after 30mins.
