Convert the video, not just the filename
Renaming MP4 to AVI does not convert its contents. Add the MP4 and choose an AVI preset to create a file with the selected container and compatible streams.

Make an AVI your destination can actually use
Check more than the AVI label
AVI can hold different codecs. Older players may limit resolution, frame rate or audio. Check your player's documentation instead of assuming that every AVI will play.
Keep only the footage you need
Before conversion, trim the beginning or end, rotate a recording or crop unwanted edges. Preserve the aspect ratio when resizing, especially when moving between widescreen recordings and older displays. Edits that alter the picture require encoding.
Try the destination before a large batch
Open a converted sample in the intended player or editor. Check picture shape, movement and sound. When the settings work, save a custom preset for the remaining files.
How to convert MP4 to AVI
1. Add an MP4
Open the Suite, add your recording and inspect its source information. Keep the original file for future use.
2. Choose an AVI preset
Find AVI in the output browser. Adjust compatible codec, frame size, frame rate and audio settings for the destination.
3. Test and export
Create a sample and check it on the intended player. Select an output folder and convert your full video.
Choose around the device's requirements
| Option | When to choose it | What to check |
|---|---|---|
| AVI output | A player or application specifically requires AVI. | Match the supported codec, frame size and audio. |
| Smaller dimensions | The player rejects high-resolution recordings. | Keep the aspect ratio and test the picture. |
| Keep MP4 | The destination already accepts the original file. | Avoid an unnecessary extra encoding step. |
MP4 to AVI questions
Will the AVI work on every older player?
No. AVI support varies by device and by the codecs inside the file. Check the player's requirements and test a sample.
Is converting to AVI lossless?
Ordinary AVI presets can re-encode the video. Do not assume the result is lossless; choose appropriate quality settings and keep the original MP4.
Why is my AVI larger than the MP4?
Output size depends on duration, video and audio bitrate, codec and quality settings. Changing the container name alone does not determine file size.
Can I convert several MP4 files together?
Yes. Add them to the queue and apply an AVI preset. Per-file output settings are available when individual recordings need different treatment.
