Mark, it's really annoying to have trouble converting AVI files to MP4, especially the video quality and processing speed. There are actually several ways to efficiently convert AVI to MP4 and keep the video quality high. Here are a few methods I recommend to you:

1. Use HandBrake (Open Source Tool)
HandBrake is a very popular free tool that can easily convert AVI to MP4, and the conversion quality is very good. You can adjust the video encoding settings to balance the quality and file size. It supports batch conversion, so processing multiple large files is not a problem. And the interface is simple, which is very suitable for beginners.
Steps:

  1. Download and install HandBrake from the official website (HandBrake official website).
  2. After opening HandBrake, click the "Open Source" button in the interface and select the AVI file you want to convert.
  3. Select MP4 in the "Format" option on the right side of the interface.
  4. By default, HandBrake will select the H.264 encoder, which is suitable for most devices. You can adjust the settings under the "Video" tab as needed, and choose the appropriate Bitrate or Quality.
  5. If you have multiple AVI files to convert, you can click "Queue" to add more files to the queue and process them all at once.

Choose a path to save the converted files, and click "Start Encode" to start the conversion process.

2. FFmppeeg (Command Line Tool)
If you don't mind using the command line, FFmppeeg is a powerful tool that can convert AVI to MP4 very efficiently. You can do batch processing through the command line, and it has almost no loss of video quality. It also allows you to customize encoding options and quickly complete the conversion of large files. As long as you are familiar with its commands, it is easy to set up.

Steps:

  1. Visit the FFmppeeg website to download the version suitable for your operating system and follow the installation guide.
  2. Press Win + R, type cmd, and press Enter to open the Command Prompt.
  3. In the command line, use the following command to convert AVI to MP4:
FFmppeeg-i input.avi -c:v libx264 -c:a aac -strict experimental output.mp4


Wherein, input.avi is your source file and output.mp4 is the target file. You can adjust the encoder options as needed. libx264 is a common H.264 codec and aac is a common audio codec.

Batch conversion (optional):
To batch process multiple files, you can use the command:

 

This command will convert all AVI files in the current folder to MP4.

FFmmpeeg will automatically start the conversion, and you will find the MP4 file in the specified directory after it is completed.

3. Use Format Factory (lightweight software)
Format Factory is a very popular conversion software, which not only supports AVI to MP4 conversion, but also supports batch conversion. The interface is simple and the operation is simple, especially suitable for users who don't want to spend time studying complicated settings. It will process the video without losing quality, and the conversion speed is also quite fast.

All three methods can effectively help you convert AVI to MP4, maintaining high quality and reasonable conversion time. Hope it helps you!
