App: Rotate & Flip Any Video
Developer: Anand
Genres: Photo & Video, Utilities

Super simple to use. Just 3 steps:
1. Drag & Drop any video.
2. Set the desired orientation by rotating or flipping.
3. Click Save Video. That's it!

Availability of 2 Modes. Fix Flag / Transcode:
    Fix Flag (Quick): Only the orientation flag (rotation tag) in the metadata of the video file is changed, so that the video plays fine in iOS, QuickTime & VLC video players without any need for transcoding which saves a tremendous amount of encoding time for longer videos.
     Transcode (Slow) : The video is rotated permanently frame by frame by re-encoding which is compatible with all video players.

The App automatically detects and displays ‘Fix Flag' option only if the input video codec is h.264 or h.265(HEVC) and not flipped, otherwise the video is transcoded with specified settings to play in any video player.

● Any Input Video. Supports almost all input video formats, codecs, containers and file extensions.
● Lossless. Zero loss in quality for ‘Fix Flag’ mode.
● Incredibly Fast. Since there is no encoding involved in ‘Fix Flag’ mode.
● Transcodes only if necessary or specified. 
● A high quality, widely compatible .mp4 (H264/AAC) output video gets created for ‘Transcode’ mode.
● Input file extensions supported are : .mp4, .mov, .m4v, .mpg, .mkv, .avi, .dv, .flv, .ts, .mts, .m2ts, .oog, .webm, .wmv, and many more…
