The video file formats consists of wide range of formats, which use different codes to encode and compress video data.
We are generating the video versions based on 2 types of video aspect ratio and they are:
In the live view, the videos are displayed in original dimension. Live view considers video dimensions as the same dimensions uploaded. That is, if an uploaded video dimension is 1920 X 1080 then the live view video size will also be 1920 X 1080. If the uploaded video dimension is 1024 X 768 then the live view video size also will be 1024 X 768.
Video with higher dimensions: The ZIZERA Applications (ZIZERA Viewer) plays with higher resolution videos.
Even when videos with higher dimensions and higher resolution are provided, the Publisher maintains the quality of the video played.
Note: If low quality videos are provided or used in the Publisher, the quality of the video in the ZIZERA Applications (ZIZERA Viewer) will not be maintained.
The video dimensions (W x H in pixels) are processed by a back-end process.
Video encoding is also known as video conversion which is a process of converting a given video input into a digital format that is compatible with most types of Web players and mobile devices. This is because different browsers, video players, and devices support or can play videos in different formats.
In order for the ZIZERA Publisher to support the same video format, it is necessary for a video to be encoded into the required format.
The required video encoding formats are:
h264 H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 (decoders: h264 h264_vdpau)
(Encoders: libx264 libx264rgb)
The above mentioned formats are the most acceptable codec format.
Audio codecs are used to handle audio and different codecs offer different levels of compression and quality.
The MP4 container format with the H.264 video codec is natively supported by desktop/ mobile Internet Explorer, Safari and Chrome. The device hardware can handle the profile used to encode the MP4.
By default, the AAC audio format is supported.
The video header includes few configurations settings which are supposed to be integrated in the source video.
In the Adobe Premiere, the 2 video settings listed below are integrated while generating the video. These 2 settings listed below needs to be available in the source video:
The video plays differently for different devices in the ZIZERA Applications.
The ZIZERA Applications supports the following video versions in different devices:
Find below the different modes in which the video plays in the Applications.
Note: For iOS devices, it is to be noted that the full screen mode plays video in the native player.
