Frequently Asked Questions

  • Will I have to create an account to use the converter?

    Our website does not require you to sign up or create an account. The platform is absolutely free and you can compress as many files as you want.


  • What is video bitrate?

    Bitrate refers to the amount of data transferred at any given time. A higher transfer speed means more data passes through, and a higher bitrate provides a better-quality video. Simply put, the higher the bitrate the better is the quality of your video. This doesn’t mean you can go overboard with it. Higher bitrate also means higher buffering time. So, it will all depend on your requirement. Bitrate is measured in bits per second(bps). Since bits are lesser values, we use terms like kilobits, megabits, gigabits, depending on the usage. With WEBM to MKV converter you can select your own bitrate, at which you want your videos to be processed. The default measurement is kilobits per second. AVI to MKV converter allows you to choose encoding speed i.e., the speed at which you want to convert the video and save it for download. The encoding speeds available with WEBM to MKV converter are ultrafast, superfast, very fast, faster, Fast, medium, slow, slower, very slow.


  • What is video encoder?

    Video encoding is a process done to make video files smaller through compression. It is done to convert analogue recordings into digital and to make videos that you would play on the internet. The tools used for video file compression and playback are known as “codecs”. There are many codecs available such as H.264, MPEG-2, VP9, WMV, HEVC and Quicktime. A video may be compressed using different codecs and if you don’t have software that is not capable of playing the video of that codec, the playback fails. At WEBM to MKV converter you can find the two best different codecs available, H.264 and MPEG4.

  • Will my uploaded files be saved on the server?

    Our website works on cloud server and does not save your files. Your files will be completely safe with you, after you have converted your file.


  • What video encoder should I choose?

    The best video codec is H.264. Almost every device that exists supports this codec and it is the most commonly used codec. You can watch H.264 encoded videos on laptops, smartphones, desktops, smart TVs, tablets, gaming consoles and almost every other device which supports video formats. MPEG4 has a slower compression rate as compared to H.264. The image quality and playback are more fluent for files encoded with H.264 encoder. It also has a small file size as compared to MPEG4. Videos are made by multiple still photos taken and projected onto a screen, per second. Frame rate or frames per second is the speed at which pictures are shown in a second. For a normal motion picture 24 frames per second is the standard rate. It means 24 pictures are shown within a second, which looks like a video.

Basic information A WEBM file is a video saved in the WebM format, which is an open, royalty-free video sharing standard. WebM holds both audio and video data in a container structure comparable to the Matroska (.MKV) video format. The VP8 or VP9 video codecs are used to compress video, and the Vorbis or Opus audio codecs are used to compress audio. A video file saved in the Matroska multimedia container format is known as an MKV file. It can handle a variety of audio and video codecs, including.SRT,.SSA,.USF (Universal Subtitle Format), and VobSub subtitles. Short video clips, TV shows, and movies are commonly stored as MKV files.
Detailed information WEBM file types are intended for use in HTML5 videos that employ the Matroska file container and are royalty-free. WEBM video playback is supported by Mozilla Firefox, Opera, and Google Chrome, however Internet Explorer 9 and Safari typically require third-party help (such as QuickTime) to play WEBM media. As part of their HTML5 player experiment, YouTube uses WEBM files. To play WebM media files, you'll need to download a WebM plug-in if your browser doesn't support it (like Safari or Internet Explorer). WebM is a royalty-free, open-source replacement for the patented H.264 and H.265 standards. The technology is suited for both business and non-commercial purposes because it is completely free. The Matroska Multimedia Container (MKV) is an open and free standard for video data storage. The file can contain an unlimited number of audio, video, image, and subtitle tracks, making it a handy way to save movies, full TV programmes, and more. The user can jump to all of the different data tracks in the raw format. It's comparable to the.AVI,.ASF, and.MOV formats in that it may have a variety of video, audio, image, and subtitle tracks. Matroska Video files are multimedia files that use the Matroska container format to store one or more video tracks and are identified by the.mkv file extension. The MKV format, which is commonly used to save short video snippets, TV series, and movies, has gained popularity among anime fansubbers. Many of these users add subtitles, and the MKV format is particularly handy because it allows for several audio and subtitle tracks to be combined in one file.
