Programs used to perform the conversion from avr file to mp4 format.
avr to mp4 conversion is in most cases searched in the context of the export of old CCTV security recordings to MP4 format, something that can be incredibly difficult to achieve, especially for very old cameras.
The best way to approach this, is to find out the manufacturer of the camera that produced your AVR video recording and search for an official tool for playback / export. Often, these videos are not meant for future export simply because they contain various metadata (time stamps) and, in their proprietary (untampered) format, can be used as evidence.
We do not have information about any standard video converter that supports the AVR format, nor does it seem that any current camera vendors still feature this format.
