Beginning with version 8.3 Total Recorder supports MPEG-4, 3GP and MOV formats under Windows 7 and above. Note that Total Recorder Standard and Professional Editions can work only with audio within these video containers while Total Recorder VideoPro and Developer Editions can work with both audio and video.

There is no need to install a third-party component to play or record MPEG-4, 3GP or MOV files. However, when working with these types of files in Total Recorder you should be aware of the following:

• Each of these file types is supported only beginning with the Windows 7 operating system.
• Only files with AAC audio streams are supported.
• Encoding to an AAC audio format requires the following attributes: 1 or 2 channels; 44100 or 48000 Hz; 96 kbit/s, 128 kbit/s, 160 kbit/s, or 192 kbit/s.
• For playback, only video files with AVC/H.264 or MPEG-4 part 2 video streams are supported.
• Playback of video files with AVC/H.264 video streams can only be done at normal (x1) speed.
• While saving files or performing recording, only encoding to AVC/H.264 video format is available.
• A MOV file cannot be created. You can play back a MOV file or re-save it in another container.
• If a video file has several audio streams then Total Recorder can preserve only one of them when re-saving the file.
• If an MPEG-4, 3GP or MOV video file contains B-frames then these frames will be lost when re-saving the file without conversion.
• A file greater than 4GB in size cannot be created.
