Frequently Asked Questions

Tips & Best Practices

• Start with trimming: Trim your video first to reduce processing time for subsequent edits like rotation or speed changes.
• Use the live preview: Check the live preview panel to verify all transformations look correct before clicking "Apply Changes."
• Close other tabs: For faster processing, close unnecessary browser tabs and applications to free up system resources.
• Use MP4 for best results: MP4 files typically process fastest and most reliably. Convert other formats to MP4 before editing if possible.
