Clarification question on Combine or Cut

Post by teredactle » Mon Jan 13, 2020 6:26 pm

Hi gang,

New user here, I am currently using the trial version to see if this will be a good option for me. I am using this for my baby monitor camera. I like to keep some days of his sleeping, tossing and turning. Even though the camera uses a SD card, that is manually too much work to sort through the 1 minute clips, combine them, etc, et to have a single video PER day.

So I am using BI to automate this for me. Camera is pointed on the crib, I have set up motion detection/triggers, etc, have tested using clips each time he moves in the crib. Working pretty well I'd say.

So my question on "Combine". I understand that if you select a number of hours that 24h is divisible by, those videos will be split accordingly. I.e. 8hours means 3 videos (theoretically).

>>I just want a single video per day. Assuming the total number of motion detected videos clips would add up to 3 hours, can I use 24hours in the setting, in which case it would create a single daily video? I don't believe the video length would even reach 500MB, so I'm not worried in this respect, although I have max set for 4GB.

This if for night time, but I may also leave it for his afternoon naps; video is B&W (via the IR lights on the camera) as the room is always made dark for his sleeps..

Thanks in advance.

If anyone else is using this for the same purpose, I would appreciate any tips on optimizing the motion detection and triggering; I believe it's ok, but hard to say w/o comparing the detected clips versus a full nighttime video to see if everything was detected.

It doesn't look like this is working as expected. I have set the hour setting to 24 hours (and size to 4GB), however I am seeing more than 1 file created. I am saving the files as MP4 format, not BVR. The help file mentions BVR format, however I don't think this is the issue as the MP4 files have more than 1 clip of motion combined.

If the cut time specified equally divides a day, such as 2, 3, 4, 6, 8, or 12 hours, recording will be aligned to the realtime clock. That is, if you have a cut time of 12 hours, yet start recording at 11am, a new file will be created at 12pm to cover 12pm-12am. The Blue Iris BVR file format allows for appending and continuation across camera or software restarts, however, so this effect will be mitigated when possible.

Does anyone know if a 24 hour period is supported here (or what I should have as the setting for hours, if 24 is not supported)?

Thanks

I posted a reply to this with more info, was never approved. Not sure what is the point of this forum then.

Basically I would like to know if what I am trying to do is supported, in that if I set the time as 24 hours on the Combine or Cut option, will it combine all the motion triggered events into 1 daily file.

I was ready to buy this software, but it seems that with the time set for 24 hours, I am getting several files (4) which I would expect to have if it was set for 6 hours.

Is this a bug?

According to the BI help, the Combine or cut examples are: 2, 3, 4, 6, 8, or 12 hours.

I've tried 12 hours, but not 24. I use 6 hrs. I'll try one camera at 24 hrs.

Thanks, would appreciate it if you would post back with the result.

I'm using MP4, and this function doesn't work as expected, if I put in 12H it still splits videos in more than 2.
Tried BVR with 24H, and still got 2 videos.

Not sure if either option would be affected by let's say, video connection failing, then reconnecting, or other disruptions "network" related. From what I gather, the BVR mode can patch these sort of disruptions, but not the MP4 streams.

Having to convert/encode the BVR to MP4 is too much for my system (I have a Xeon 1255v3), so I will stick to MP4, combining the clips this way is super fast with ffmpeg and I have a script that I wrote to do it.

Another poster on reddit said he tried 24H for BVR and it created 1 file, but it didn't work for me.

Also, just some further things I've noticed here.

If saving to MP4, and selecting the time divisions 2/4/6/8/12, the file doesn't get cut properly. I.E.
I would like it to start a new file after midnight, that way I can just combine the clips for the full day, but I see that isn't working with MP4.

How would I go about getting some official confirmation as to the limitations of this feature, using direct to disk mp4 writes? I would like to get this information before I spend money on this software; the help file is just ok, but it lacks examples and better explanation, as well as a legit "this feature only works on BVR files, not MP4" messaging for features where it's necessary to understand this.

After changing one camera to 'Combine or cut' 24 hrs, it does indeed cut at 24hrs. I'm also using Direct-To-Disk BI DVR.

Interesting, thanks for posting back!
I assume it cuts at midnight, so the 24h video is from 00:00:01 to 11:59:59?

Yes, from 12:00:00AM to 23:59:59PM.
