Auto
Sets how the video is encoded. "Auto" suits most conversions. "Copy" reuses the video as-is, so it is fast and keeps full quality, but only when the output format supports it.
No change
Choose how the video is resized: to a set resolution, or to a different aspect ratio, where the video's width is kept and the height is recalculated to match. Select "No change" to keep the original size.
No change
Sets how many frames per second the output video has. Lowering it reduces file size but makes motion less smooth, and raising it above the source frame rate won't add smoothness. "No change" keeps the source frame rate.
None
Rotates the video clockwise by the angle you select. Choose "None" to leave it as-is.
No change
Flips the video horizontally or vertically. "No change" leaves it as-is.
Upload
Select the best option for your subtitles: 'Upload' to add your own, or 'Copy' to replicate from the original file.
Choose a file Browse
Upload a .srt or .ass file.
Hard
Choose how subtitles are added. "Hard" burns them into the video permanently; "Soft" keeps them separate so viewers can turn them off. Default is Hard.
Auto
Sets how the audio is encoded. "Auto" suits most conversions. "Copy" reuses the audio as-is, so it is fast and keeps full quality, but only when the output format supports it.
100% represents the original volume. To double the volume, increase it to 200%. To reduce volume by half, select 50%

Advanced Systems Format (ASF) is a proprietary Microsoft product, which serves as a container for Windows multimedia content. Microsoft designed it for streaming and to be independent of systems and protocols. It supports chapters, captions, subtitles, metadata tags, streaming, and hardware players, but does not support menus.

 

How to open an ASF file?

It is best to use Windows Media Player to open an ASF file. Alternatively, VLC media player is a good choice too. Keep in mind that ASF can contain WMA and WMV files, which might display as the file extension of the ASF file.

Initial release: 1995

iPhone Video is an MP4 file encoded specifically for playback on Apple iPhone. It pairs H.264 video with AAC audio at a resolution, frame rate, and bitrate the device handles smoothly, so the clip plays without stuttering and without draining the battery. Choosing this preset means the video is ready for the iPhone straight away, with no re-encoding on the phone itself.

 

How to open an iPhone Video file?

On the phone, an iPhone Video plays in the built-in Photos or Files app the moment you tap it — no additional software is needed.

 

The same file also plays on any desktop computer: QuickTime on macOS, Windows Media Player or the Movies & TV app on Windows, and VLC media player everywhere. To move the file onto your iPhone, sync it through iTunes or the Finder, or simply save it to iCloud Drive. Our video converter can re-encode a clip for a different device or format.
