Is your video sideways? Send it to me through Whatsapp and I'll rotate it. Up to 3 videos per gig.
Two methods of rotation available:
1) Decode->Rotate->Re-encode: With quality loss. Compatible with most players.
2) Orientation flag change (completely lossless) Compatible with iOS and QuickTime. Some media players won't honor the orientation flag.
Only MPEG-4, MOV and MP4 format files up to a 100Mb.
