FAQs of MP4 Rotation

1. Can I rotate mp4 in Windows Media Player?

No. Windows Media Player is pretty good and easy for playback of video files, including HD and blu-ray standard. However, it doesn’t support video rotation. As a result, you will have to rely on a third-party tool with the option of rotating and flipping video file.

This one very much depends. If the source MP4 file is small enough, generally less than 100 MB in size, rotating MP4 online is of course a good option since the whole process is pretty easy and you don’t have to download any software on your computer. But if the MP4 file you recorded is pretty large with high resolution, it is absolutely good to use desktop software to rotate MP4 file instead.
