Split merge compress edit video files4/22/2024 Show codec label for HEVC videos, very easy to distinguish them from H.264 videos View videos in the orders of creation date, modification date, file size and albums Rotate video clockwise or anti-clockwise Preview the merged video, export to camera roll instantly Select and view video clips in the order of creation date and modification date Support merging up to 6 video clips to one video Split video clips are exported in the same resolution and bitrate as original video Split position's precision can reach 0.1 second Insert or remove a split point is very easy and straightforward One video can be split up to 5 to 7 clips, export and save to Photo Library Trimmed or cut video is exported in the same resolution and bitrate as original video Automatically calculate and display trimmed or cut video’s duration Easy scrolled video preview make trim position’s setting very convenient and accurate Support setting export format, delete and storage album option for all editing functions Touch other part of the cropped video, drag to adjust it’s position in original video Touch the lower right corner of the cropped video, drag to adjust it's resolution Automatically add creation date metadata to videos without it, prevent from losing video's creation or capture date Retain all metadata of original video, including timed metadata info in metadata tracks Compressed video can be saved to a user selected album Provide preview function for checking compressed video’s image quality Input any compression bitrate through keyboard Multiple bitrate options for each resolution and frame rate option Support adjusting frame rate, 240 FPS's video can be compressed to 240/120/60/30 FPS Resolution options for HEVC Compression: 4K, 1080p, 720p Support batch and single video compression Support HEVC & H.264 codec, save more storage than traditional H.264 compressor. To choose this option, choose "Re-size video" from "Advanced Settings" above.A full-featured and easy-to-use video toolbox, can be used to batch compress, crop, trim, cut, split, merge and rotate videos in Photo Library. For example, if you have a 4K (4320p) video but your target device is 1080p, you can downsize the video to fit 1080p and save file size. 4: Make Video Size Smaller (Re-Size)Ĭhoosing a smaller video resolution (dimensions) can also save file size. For more info: read video bitrate control. To choose this option, select "By Max Bitrate" from the "Video Compress" dropdown. Select this method if you are using the video in a streaming application where you want to control the streaming bandwidth rate. The quality is set by CRF (constant rate factor). This method allows you to set the max bitrate for given video quality. This is the default video compression method used. Increase the target size if you need better quality. To overcome this, start with a decent size (as a percentage of original), then test for video quality. The downside is you don’t know how the target size will affect video quality. The pros of this method are, you can achieve a certain target size. For example, if you set it to 60% for a 1Gb file, we will attempt to make your compressed file size 600Mb or less. This method allows you to set a target file size for your video as a percentage of the original size. As a Percentage of the Original Size (Default) If you prefer a lower file size over encoding time, choose a slower preset. Choosing a slower preset allows better optimization (lower bitrate/file size) for a given video quality level. Preset: Presets refers to the video compression speed. Higher values mean more compression (reduced file size), lower values mean better quality (but bigger file size). For the H264 encoder, possible CRF values range from 0 to 51. To do that, it uses different compression levels on different frames. By Video QualityĬRF (Constant Rate Factor): CRF method attempts to keep a constant perceived video quality. We provide 4 settings related to both methods. You can either optimize the bitrate or resize the video to a smaller size. There are two main methods to compress a video.
