Frequently Asked Questions

Why is my phone video sideways?
Phones store orientation as a hint that some players and editors ignore. Rotating it here bakes the correct orientation into the video itself, so it plays the right way everywhere.
Will rotating reduce the quality?
The video is re-encoded once with high-quality H.264 settings, so the difference is not visible in normal viewing.
Does it keep the sound?
Yes, the audio track is kept and converted to AAC so the MP4 plays everywhere.
What format is the result?
An MP4 (H.264 + AAC), the most widely supported video format.
Is there a file size limit?
No. Files over 1 GB work too; the only limit is your device's memory.
