[Yandex Cloud documentation](../../index.md) > [Yandex Cloud Video](../index.md) > [Concepts](index.md) > Videos # Videos in Cloud Video With Cloud Video, you can upload _videos_ to your [channel](index.md#channels) for subsequent publication on external resources. You can upload videos in various supported formats, such as [MP4](https://en.wikipedia.org/wiki/MP4_file_format), [AVI](https://en.wikipedia.org/wiki/Audio_Video_Interleave), [MKV](https://en.wikipedia.org/wiki/Matroska), [FLV](https://en.wikipedia.org/wiki/Flash_Video), [MOV](https://en.wikipedia.org/wiki/QuickTime_File_Format), [WebM](https://en.wikipedia.org/wiki/WebM), etc. You can [download](../operations/video/upload.md) videos either one by one or several at a time. By default, video playback starts only after processing if the browser supports the source file. You can change this in the channel settings. Then the source file will be played immediately, without changes, and will contain the original metadata. You can upload videos with multiple audio tracks or add them after uploading using [neural translation](videos.md#translation). Select the tracks in the [player](player.md) menu; read more in [Selecting audio track](../operations/player-control.md#audio). [Cloud Video limits](limits.md) the resolution of the videos you are publishing. You can upload custom covers for your videos. The cover will appear in the Cloud Video interface and the [player](player.md) on the website hosting the video. The following cover formats are supported: [JPG](https://en.wikipedia.org/wiki/JPEG), [PNG](https://en.wikipedia.org/wiki/PNG), and [GIF](https://en.wikipedia.org/wiki/GIF). You can [publish](../operations/video/get-link.md) a video and select its access type: * **By temporary link**: Available via a dedicated link. {#temporary-link} The video is available via a temporary link for a maximum of 12 hours. * **All users**: Available indefinitely to anyone with a link to it. {#permanent-link} On the website, you can post both single videos and [playlists](playlists.md) with videos in a particular order. In playlists, only videos with permanent links will be available for viewing. For more information on publishing playlists, see [Getting an embed code or link to a playlist](../operations/playlists/get-link.md). ## Statuses {#statuses} ### Video statuses {#video-statuses} * `Uploading`: Original video file is being uploaded to a Yandex Cloud storage. * `Processing`: Original video file is transcoded into several video versions with different bitrates and resolutions. When viewing the video on client devices, the video player selects the best version for smooth playback at a given internet connection speed. * `Ready`: Transcoding is complete. The video is ready for viewing. * `Error`: Error uploading a file or transcoding a video. Check the stability of your internet connection, the integrity and format of the file and try again. ### Publication statuses {#publication-statuses} * `Published`: Video is [published](../operations/video/publish.md). * `Unpublished`: Video is not published. ## Video publishing parameters {#video-parameters} You can change the following basic video playback settings when [generating](../operations/video/get-link.md) a direct link or website embed code: * Default sound setting for video playback. * Automatic start of playback when opened. * Displaying video controls in the player. With [Cloud Video Player SDK for IFrame](../sdk/iframe/index.md), you can specify additional player control and video playback settings for an HTML page, e.g., video size and looping, volume, etc. Also, you can use [presets](presets.md) to configure some of the player settings, e.g., widget color palette and layout. ## Video viewing statistics {#video-statistics} For each video, you can [look up the viewing statistics](../operations/video/get-statistics.md) and flexibly customize the statistics period. The following viewing statistics are currently available: * Number of views: Integer. * Share of viewed content: Percentage ratio of average viewing time to video duration. * Total viewing time: Total viewing time in hours and minutes. * Average viewing time: Average viewing time in hours and minutes. * Linear chart with distribution of the number of views per unit of time with the following discretization levels: * `5 minutes` * `1 hour` * `1 day` * Pie chart with distribution of views by device OS type. * Pie chart with distribution of views by device type. * [Heat map](https://en.wikipedia.org/wiki/Heat_map) with data on video fragment views. Each point on the heat map corresponds to a 30-second video fragment. On the heat map, the fact of video fragment playback is counted as a view regardless of playback duration. For example, if you start a video and stop it right away, a view will be counted for the first fragment of the video. ## AI features {#ai-capabilities} To provide users with more options and expand your video audience, enable AI features built on Yandex ML models. For more information about AI features, see [this article](https://habr.com/ru/companies/yandex/articles/792608/) in the Yandex blog. ### Summarization {#summarization} [Summarization](../operations/video/summarization.md#enable) automatically creates a short summary of your video conveying its main points and key message. Summarization is available for videos with duration of no longer than four hours. With summarization enabled, the system automatically adds timecodes to videos. You can adjust the suggested timecodes or [add custom ones manually](#timecodes). ### Neural translation {#stranslation} [Neural translation](../operations/video/translation.md) enables the automatic translation of video content into multiple languages and voiceover with [diverse voice options](https://habr.com/ru/news/905118/). View the list of supported languages in the [Cloud Video interface](https://video.yandex.cloud/). ### Subtitles {#subtitles} Neural [subtitles](../operations/video/subtitles.md) not only include spoken text but also provide speaker differentiation. Each speaker switch is indicated by a dash and new line, making the dialogue easier to follow. View the list of supported languages in the [Cloud Video interface](https://video.yandex.cloud/). You can also upload custom subtitles in SRT and VTT formats. The maximum subtitle file size is 500 MB. You can load several subtitle files in one or more languages for one video. ## Timecodes {#timecodes} [Timecodes](../operations/video/add-timecodes.md) allow you to break the video into chapters that you can navigate while watching. The time and chapter name formats are as follows: ``` 00:00:00 Episode 1 title hh:mm:ss Episode 2 title ... ``` {% note info %} Timecodes must begin with `00:00` or `00:00:00`. The time is separated from the episode title by a space. Each timecode begins from a new line. {% endnote %} You can also generate timecodes automatically by enabling video [summarization](#summarization). ## Useful links {#see-also} * [Getting started with video hosting](../hosting.md) * [Getting started with API](../api-ref/quickstart.md) * [How to enable monetization](../operations/channels/settings.md#ad-settings)
