How do I convert MP4 to AVI using LetsConvert?

Upload your MP4 file, then choose AVI as the target format. Select your preferred codec (e.g., DivX or MJPEG) and adjust video bitrate, resolution, and audio settings if desired. Click 'Convert' and wait for the process to complete; then download your converted AVI file. Batch conversion is supported to convert multiple MP4 files at once.

Why convert MP4 to AVI instead of sticking with MP4?

MP4 is a modern container using high-efficiency H.264 compression, making it perfect for web streaming but often incompatible with older video editing software, VCRs, or DVD players. AVI is a legacy container that supports a wide range of codecs like DivX, Xvid, and MJPEG, making it easier for professional NLE tools to import files without re-encoding. By converting to AVI, you ensure compatibility with equipment and software that only accepts AVI format.

What happens to the video quality and audio bitrate during MP4 to AVI conversion?

When converting, you have the option to preserve original resolution and frame rate. For video, you can choose a lossless codec like MJPEG to keep every pixel, but file sizes will grow; alternatively, H.264 in AVI retains compression but might require an additional codec pack for playback. Audio is typically transcoded from AAC to PCM or MP3, which can increase audio bitrate and improve compatibility with AVI's CBR structure. Color profiles and metadata are converted to AVI's older, container-specific tags, so you may need to reset color space if your NLE expects BT.709.
