Converting AVTech VideoViewer Backup (*.avc) to Video Format (*.avi)
Last Updated a year ago

The downloaded .avc file from VideoViewer requires the Player (VideoPlayer) from AVTech in order for you to playback.
In some circumstances, you might want to convert it to a common video format (.avi) file as the party you are sending the backup video to might not have and is not willing to install the videoplayer software.
Do note as the .avc file is a highly compressed video format file, the converted video might be a lot larger in size than the original backup file. The format you converted to and the quality of the re-encoding might also reduce the quality and resolution of the backup video.

Here's how to convert the .avc file to a common avi format that you can playback on any video player that support the format.
You will require the VideoPlayer program. It should installed automatically with the VideoViewer program. However, in certain cases, the backup file might required a newer version of the VideoPlayer program in order to playback properly.
In that case, download the VideoPlayer software from here. (
Run the VideoPlayer and open the backup file, or alternatively, double click on the backup file.
Video Viewer should open with the backup file playing.


Click on the AVI Icon. It'll automatically convert to AVI file and store on the default location (Your Windows Desktop).
That's all to it, as simple as that. The time taken to convert will depends on your video length and the speed of your computer.
The following are some advance options that you can tweak.

Codec is the format of the video that the Video Player will save the video in for playback.
To select the codec, do the following.


1. Click on the Config Settings
2. Click on the Codec Button
3. Select which codec you want to save the video in. The Video Compression Codec available on your computer might be different depending on the type of media player/converter you had installed on your computer.
The more common one is the Cinepak Codec by Radius and the Full Frames (Uncompressed). We would advice you to save in the Cinepak Codec by Radius as it is a preinstalled codec that's available on all Windows computer, which means all window computer's media player would be able to playback this video without additional software installation.
The Full Frames (Uncompressed) is also commonly playable on ALL media player as there's no compression done on the video. However, as there is no compression done, the result video files would be huge, often around 20-40 times the original size. We do not recommend this unless you know what you are doing.
The best would be MPEG-4 or H.264 compression. However, this does not come by default with Windows and it required other software installation. If you see that option in the list, it means that you might have other media player that had already installed the codec for you and you can try selecting that and see if it works. If not, select Cinepak Codec by Radius.
4. Click on OK to get back to the Config Settings menu.
5. Click on OK to get back to the Video Player.

TRIMMING (Converting only Part if the backup file to Video .avi file).
You might not need to convert the whole video file to avi file as the video file might contain other segment of unrelated video. Instead of re downloading the exact period that you need again and convert the whole backup file, this is what you can do.


1. RIGHT Click on the timeline on the start of the segment you want to convert to AVI file.
2. RIGHT Click on the timeline on the end of the segment you want to convert to AVI file.
3. RIGHT Click on the timeline again, and the option to Record the segment you want to save to Video .avi file would appear. Click on *.avi and the segment you selected would be saved to the AVI file.
Remember it's RIGHT CLICK. In case you select a wrong segment, click on Clear all and repeat the steps to select.
