.dvr file format video codex, or software translation

by jbrooks / March 26, 2005 5:18 AM PST

I have a new Digital video recorder, it runs in Lynx OS it has a ActiveX viewer and records digital video in a .DVR format (not .dvr-ms). I would like to edit and copy these .dvr files in any format.
I am looking for a codex, or a converter, I can use to convert the recordings to MPEG AVI or MOV or play it in something other than the ActiveX player. or what codex does it use. Any suggestions ?
Copy of a sample video (6Meg) and the player

Thanks, I am looking, I down loaded an eval copy a few minutes ago. It does not do .dvr direct from file. I am trying to do the screen capture now.

Thanks, I down loaded an eval copy a few minutes ago. I am trying to do the screen capture now. I believe this will work. You are my hero. I captured a segment to AVI, I can work with that. I have tried several ways and THIS WILL WORK.. I can not thank you enough, this will save the investment in the DVR and let me take 100MB files to 15KB for distribution.
If I can ever do anything to repay the favour to you please let me know.

To fill in the blanks so I don't have to do much research on the internet about your devices. I never figured out what you had so all I could offer is CAMTASIA.

.dvr conversion

I apologize for the lack of data, Probably comes from not knowing much. I had not found the OEM Web site. It appears the server is put together using common parts and the system builder is a box assembler and was no help with the software. It is a brain dead system with no options. You turn it on and it records what ever cameras are selected, Period... The recorder is a plain box, Linux 3.0Ghz pentium, 1Gig memory with a 250Gig HD. It has 4 vidoeo recorder cards for 16 cameras. To edit or view we are using several NT/XP machines from 1Ghz to 3.2. Pulling the data from a fire wire or USB HD does not seem to make a difference in performance.
The CAMTASIA eval copy seems to be working, but it is a little quirky ( not too stable and freezes after saving the AVI. The player for the .dvr has two sizes to big and too small. The segment screen capture at a portion of the 325 X 480 player will capture at 12FPS, selecting a smaller zone will speed up the frame rate to 15 and 27. Loosing allot of frames on the capture method. These is a sample of the .dvr video file and player on the first posting. If there is a product that might allow for a direct conversion, or batch conversion that would be good. I have about 240 each 30 min dvr files to edit and cut. a 30 minute segment (100MB) might have 2~3 minutes of usable data. It is a slow process, still trying to capture and convert a singe file series. Still looking for anything that will do a batch conversion from .drv to a windows compatable media player

I finished up a 10 camera system running on some Dell 500 buck special (XP Home) and a pair of 8 video port cards from compgeeks. The software saves to some proprietary file, but you do some click here and there and it exports to .AVI for handover to the police or whoever. Very slick and the system was under 1k for the Dell PC, LCD monitor, 16 video channels and more. It runs 24x7.

As to your hang/lockup, I have no clues to work with but can tell you I've never had that happen. However we have Windows 2000 or XP machines, no spyware or other issues to deal with.

The lack of information is disconcerting and not your fault.

I wish I had gone to the forum last fall when we were looking for a server. Our selection was based on 16 cameras, 30fps frame rate and IP server for remote viewing. It works well, but the file format and the post purchase support were lacking. I expected MPEG or at the worse .avi. I have Ask the OEM for a different OS or different recording format, but have not received a reply.

16 cameras at the full 30fps is quite a lot to ask. That could run into a lot of buck since most systems I know reduce the FPS per camera to save on encoder costs.

I've done many security systems and none required 30 fps. At the end of the day, we find 1 or 2 fps to be just fine for surveilance work. Now that we are almost entirely digital we don't see the ratty tape issue.

In closing, the .AVI can be in the MPEG encoding of your chosing. It can be named .AVI or .MPG to help in making it compatible with the enduser.

Yea, 30PFS at 16 Cameras fills up a drive in a hurry. Problem with my application is it is used in a Lab. You do an experiment that takes 45 seconds, and you have 16 100 MB files to cut out the different views. Could be worse, the 16mm film is 10K FPS and you get to wait weeks to see if you got the data. The DVR also acts as a internet server and you can observe remotely from a fixed IP. Thanks for all the help, the OEM says NO editing since security systems may go to Lawyers someday. Even if you are not using them as security systems. Look at the Geovision capture cards
