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.

Core Audio Format (CAF) is Apple’s professional audio container, introduced with Mac OS X Tiger. Unlike WAV and AIFF, which are effectively capped at 4 GB, a CAF file has no practical size limit, so it can hold hours of high-resolution multichannel audio in one piece. CAF is a container rather than a codec: the audio inside may be uncompressed PCM, Apple Lossless, AAC, or several other encodings.

 

How to open a CAF file?

On macOS, CAF opens in QuickTime Player, the Music app, Logic Pro, and GarageBand without any extra software.

 

On Windows and Linux, use VLC media player or Audacity, and FFmpeg for batch conversion. Because CAF is largely an Apple-only format, converting it makes sharing far easier — try our CAF to MP3 or CAF to WAV tool.

Matroska (MKV) is a free, open-source, container standard that can hold an unlimited amount of audiovisual and multimedia files in a single file format. Since it is open source, a user can customize it with open-source software. The name derives from “Matryoshka” dolls, which is a famous type of Russian handicraft that consists of a set of wooden dolls of decreasing size nested one inside another.

 

How to open an MKV file?

The best way to open an MKV file is to use VLC media player. This media player is compatible with all operating systems and platforms. This is important because MKV is not an industry standard, which means that other media players might not support it.

 

Additionally, MKV does not use codecs to compress file size, which means the file can be quite large. Therefore, another option for opening an MKV file is to download the appropriate codecs that are compatible with the selected media player. To accomplish this, download the Combined Community Codec Pack (CCCP) from a trusted site, such as Ninite.
