Question about converting avi to mp4 in Windows PC?

A rookie mistake is not paying attention to the output settings. When you’re converting AVI to MP4 on Windows PC, ensure that you select the right resolution, bit rate, and codec for your MP4. Sometimes the default settings aren't the best for your needs. I remember just hitting “convert” without checking, and my file ended up being way too big or losing quality. 

After conversion, you definitely don’t want your video and audio to be out of sync. That’s super annoying! Some converters have issues maintaining sync, especially with AVI formats. Always do a quick check after converting. If you find a sync issue, you might need to try another converter or adjust audio settings in the software.

When converting, the file size might end up being larger than you hoped for. If you're short on storage, it’s good to tweak the bitrate or use compression settings. I’ve had times where I didn’t realize a 1GB AVI ended up being 5GB in MP4 because I didn’t look at the settings. 

Some software can have bugs, especially if you’re using older versions. Keep your conversion software up to date for better performance and features. This has saved me some headaches when unexpected errors popped up during conversion.

Always keep a backup of your original AVI file. Sometimes conversions can fail for various reasons, leaving you high and dry without the original video. Trust me, having a backup has saved my butt more than once when I accidentally corrupted a file.
