Often DVR’s record at a variable bitrate so there may be very slight differences between files. With FIVE’s concatenation function, you can batch process all the files and then concatenate the converted files together.Ĭoncatenation is a tricky process as its important that the files have exactly the same format, codec, frame rate and bitrate. 264 files that belong to the same camera, but are continuous in time. There are also times, when you don’t want to deal with the files individually, but you wish to manage them as a single file.

log file for every file, which holds the details of the conversion process for your records.Īfter dropping the other files into FIVE, you could arrange your windows see all the views, and rename your chains as to the camera numbers. These are all identifiable with the -converted text after the filename. I could then go back into my folder and select the other converted files. The option to select these is an added bonus.Īfter hitting Ok, all the files are converted as per our parameters and the first one is opened automatically in FIVE, as detailed under the Advanced Tab. I am going to chose FFmpeg in this instance, but you may have files that can only be decoded correctly using MEncoder or AVConv. An important one is the Conversion Program to use.
Jumping ahead to the Advanced Tab, again, there are a number of user configurable options. There are a number of options here, but for this example, I have simply chosen AVI. Remember, this is the container used to ‘contain’ our stream. Under the Copy Stream Tab, we have options for selecting our Output Format. I have selected my first file, and importantly, I have chosen to convert ‘ All files with the same extension in the same directory‘. The Convert DVR tool is found under FILE. I can see from the naming convention that they are probably from 4 different cameras. Here we have a folder containing our 4 evidential files. Although FIVE has safeguards in place to ensure you don’t overwrite anything, it’s a good habit to get into! It is good practice, when conducting any sort of batch processing, to work on a copy of the folder containing the evidential files.

When working on DVR videos, how many times do you have not just a single file, but a folder full of files from different cameras of different times?Īn often overlooked tool in Amped FIVE is the Convert DVR interface that enables a user to pre- process files prior to loading.
