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%

Raw audio is uncompressed pulse-code modulation (PCM) sound stored with no header at all — just a continuous stream of sample values. Because the file carries no description of itself, the sample rate, bit depth, channel count, and byte order have to be supplied by whoever opens it. That makes raw audio awkward to share but very useful in audio programming, embedded devices, and recovery work, where a plain stream of samples is exactly what is needed.

 

How to open a raw audio file?

The standard tool is Audacity. Use File → Import → Raw Data, then set the encoding, sample rate, and channels to match the file.

 

If you do not know the correct settings, start with 16-bit signed PCM, 44,100 Hz, stereo, and adjust until the audio sounds normal — wrong settings usually produce noise or a chipmunk-like pitch. Command-line users can play or convert raw audio with FFmpeg or SoX. Converting to a self-describing format such as WAV or MP3 saves you from repeating the guesswork. You can also convert the file with our RAW to WAV tool.

MPEG-4 (MP4) is a container video format that can store multimedia data, usually audio and video. It is compatible with a wide range of devices and operating systems, using a codec to compress file size, resulting in a file that is easy to manage and store. It is also a popular video format for streaming over the Internet, such as on YouTube. Many consider MP4 to be one of the best video formats available today.

 

How to open an MP4 file?

MP4 files open in the operating system's default video player. Simply double-clicking the file opens it. There is no need for third-party software. On Windows, it opens in Windows Media Player. On Mac, it opens in QuickTime.

 

On some devices, particularly mobile, opening this file type can be problematic. MP4 is a container that contains various kinds of data, so when there is a problem opening the file, it usually means that data in the container (an audio or video codec) is not compatible with the device’s OS. To resolve this issue, try VLC media player.
