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%

Opus is an open, royalty-free lossy audio codec standardised by the IETF as RFC 6716. It was designed to cover everything from low-bitrate speech to full-quality stereo music in a single codec, and it consistently outperforms MP3 and AAC at the same bitrate. Opus powers voice and audio in WhatsApp, Discord, Zoom, YouTube, and every WebRTC browser call, which makes it one of the most widely used audio codecs in the world.

 

How to open an Opus file?

Every major web browser plays Opus natively, so dragging the file into a browser tab works. On the desktop, VLC media player and foobar2000 both support it out of the box.

 

Android plays Opus natively, and FFmpeg handles conversion from the command line. Some older hardware players, car stereos, and editing programs still do not recognise the format — in that case convert it with our Opus to MP3 tool. You can also convert the file with our OPUS to MP3 tool.

Audio Video Interleave (AVI) is a multimedia container developed by Microsoft. AVI is a descendant of the Resource Interchange File Format (RIFF). With the assistance of third-party programs, AVI can support chapters, captions, subtitles, menus, streaming, attachments, and 3D containers.

 

How to open an AVI file?

Microsoft provides a downloadable and free AVI Viewer. Another way to view an AVI file is to use a version of Microsoft Windows Media Player that is compatible with the operating system.

 

While AVI files are optimized for the Internet, hardware players support them as well. If an AVI file does not open, then use VLC media player.
