Hi there all.
If you do a websearch for '' video codecs '' or '' free video codecs, you will find a large array of codecs to download. Download them to a file or if the cctv video footage allows playback on the PC in question, download the file into the windows 32 system folder.
Once downloaded, play back your DVR video and if the software gives you the option to SAVE AS, click on it to save. Where it normally will give you the option to save as AVI only, you should now have the options to SAVE AS, any of the codecs you have downloaded.
Convert DVR to AVI or WMV for playback DVR in Window Media Player, Xbox and more or edit DVR in Windows Movie Maker.
Convert DVR to MPEG (ncluding MPEG-2 and MPEG-1) or convert DVR to VOB for burn DVR to DVD or VCD
Convert DVR to MP4 for play DVR on iPad, iPhone, iPod, Apple TV, iTunes, BlackBerry, Android Phones, PS3, PSP and more.
Convert DVR to MOV for play DVR in QuickTime, Wii and more
Convert DVR to FLV for upload HD DVR to YouTube and more.
Convert DVR to DV for editing DVR in Adobe Premiere, Sony Vegas, iMovie, Final Cut Pro or Final Cut Express.
Convert DVR to other video formats including ASF, MKV, RM, RMVB, WebM, MPG and more
There is not a lot of point in randomly downloading codecs that may or may not help your cause. What I suggest you do, is to download a (free) program called G-Spot (yes, really!!) that will tell you what the codec is.
Sometimes though, it will be in a propitiatory format, hence why I ask where the DVR came from.
