Continuous/timelapse capture - what am I doing wrong
I have the camera enabled, no motion detection. 1 second per frame. Create a new movie every 15 minutes. So I would expect to have 15 minutes of video, one picture per second. Then a new 15 minute movie. All these 15 minute movies would have a continuous recording of the camera.
What I get is a file with 4 minutes of video, the file ends. Then a new movie starts after the 15 minutes - but a hole of no recording for 10 minutes or so.

1. What version of SecuritySpy are you using?
2. Have you specified a "playback frame rate" in the timelapse settings in SecuritySpy? This will result in playback being at a different rate to recording.
3. Is the camera on a schedule, or is it in Active mode all the time?
3.2.1
yes - record 1 frame per second and 2 frames/sec playback
no schedule and active all the time
I have tried several variations and have not yet figured out the combination I want
Thanks

Thanks for helping on this.
My camera has burned in time code, and I turned the date and time on in Security Spy, (my camera time is off a little)
Capture Frequency 1 second per frame and 2 frames per second playback. 15 minutes per recording.
Movie one reported start time on file selection page = 14:20:01
Security Spy 14:20:01 --> 14:27:43 = 7 minutes and 42 seconds
Camera time 14:20:51 -->14:28:33 = 7 minutes and 42 seconds
The next movie start time on file selection page = 14:36:00
Security Spy 14:36:12 --> 14:44:01 = 7 minutes and 49 seconds
Camera time 14:37:11 -->14:44:52 = 7 minutes and 41 seconds
The gap is 8 minutes and 29 seconds of no pictures

I was at the computer doing the recording... The browser pull down has the movies with the full 15 minutes! The Quick View of the remote WEB browser has the above problem. I will look and see if the remote web browser "Full res
' does it!!
Bob
If you are using Remote Patrol there is a switch to turn on and off the Quick option.
At the computer that is running Security Spy - all the recordings are the correct length with no gaps.
But...
On another computer logged into Security Spy using Safari there are the "short" videos. From your note above, you re-encode the video, that makes sense. But is there a limit of the length of that video? Should I create a new file every 5 minutes rather than 15.
BTW. The original and the quick videos when logged in remotely both have the "short" video issue.
So why am I doing a Continuous record rather than motion trigger records? SNOW! I live outside New York City and we have had 4 storms. When it snows, even when set up for a trigger time of 2 seconds, I get about a zillion files. If only it never snowed...

With Safari you will be presented with two links for each movie download: an "Original" and a "Quick" download. the Original download is the whole, entire movie.
Please try this in a different web browser (e.g. Chrome or FireFox) to rule out any problems with Safari. Also please make sure you are allowing the whole movie to download so that you can see to the end (as these are the full-size movies, the download will take longer than the Quick movies).
Sorry about the snow issue. SecuritySpy's motion-detection algorithm does work well in most situations, however extreme weather can cause problems that are very difficult to deal with without a more sophisticated and CPU-intensive algorithm. We will be looking into this for the future.
The full movie is in fact the full movie but as you pointed out downloading those does take a while. Why would I have a gap when using the quick version. The gap is also exists using a iOS device.
What settings do I use so when downloading a quick movie there are no gaps in time.
Sorry to be a pain

It appears my calculations for the duration of the short movies are a bit off for your situation. In your scene, there's quite a lot of movement with cars going by at the road at the end, and also a certain amount of noise generated by the camera (because it's dark). This will affect the encoder's ability to produce a low data rate. The data rate is around 30 kbps for your movies. While not excessively high, this is higher than I obtained in my testing here, and does give a limit of around 4.5 minutes per quick movie. My figure of 10 minutes for the quick movies must have been calculated in different circumstances (e.g. a nice noise-free image with not much going on).
Therefore if you want the quick movies to be as long as the full movies, you could set the capture settings to start a new file every 4 minutes. This still isn't guaranteed to produce a quick movie of the full length: the quick features is designed specifically to have a 1MB size limit to enable a consistently-fast download; it's not designed to satisfy a particular requirement for video duration.
In the mean time, for the next version of SecuritySpy, I'll see if I can tweak the encoder settings (e.g. decrease the key frame rate) to squeeze some extra video duration out of the 1MB limit.
Hope this helps.
Thanks

Since I infer that this is video of a street, Bobross52 might be interested in my idea in the same post of time-lapse triggering on motion events instead of just on seconds of interval, to create timelapse films that consist only of frames of interest.
