VOD provides a rich set of transcoding features for video release. In order to deliver a better viewing experience in different network environments, you can transcode and publish videos based on the following recommended definition categories:
The detailed specifications and technical parameters of output videos after transcoding are as follows:
Right-click and select Open image in new tab to view a high-definition image.
If the resolution of an uploaded video does not match the values above, the video will be transcoded to a resolution with a standard width in the corresponding category and a proportionally scaled height.
If the resolution of the uploaded video is lower than the set transcoding specification (for example, a video with a resolution of 640 * 480 is uploaded, but the transcoding is set to HD), the system will still transcode it according to the set format (i.e., HD here). However, as the video itself has a lower definition, the user experience may be poor and traffic and bandwidth will be consumed.
VOD can transcode a video to a resolution higher than the original one, but the video quality will not be improved.
No, theoretically. The VOD system is enabled for access from anywhere at any time. Please note that the viewing experience is greatly determined by the quality of the network from user device to video server and the device specifications. Therefore, during peak hours of network service, the experience may vary due to the change of network conditions or low device specifications.
You do not need to generate the code again, because it is maintained and updated by the system automatically. After the player configuration is modified, the released player code will take effect immediately.
The URL of a source file corresponds to a video file of a specific bitrate, which does not contain any player information itself and can be opened directly in a browser for playback.
The web player code corresponds to the code that can be edited on the web, including the Flash address, adaptive HTML code, IFRAME code, player settings information (such as definition, roll content, and sharable link). This code can be embedded in a user-edited webpage.
As the custom player has been deleted, video files will be automatically associated with the current default player configuration, but the code that has already been released can continue to be used. If you need to make changes, please define the player and release the code again.
If no custom configuration is made, the default configuration will be used when a video is uploaded and published, that is, the autoplay feature is disabled. You can modify this setting by checking "Autoplay" when publishing videos.
The definition of a video during playback depends on the following two aspects:
The blocklist/allowlist can be used to allow or deny the requests for accessing videos published through player code from particular webpages.
These lists are effective to videos published through player code. You can enable this feature globally and specify a blocklist or an allow list. Each list can contain up to 10 URLs by checking the referer of access source. For more information on how to protect video file URLs, please see Hotlink Protection Overview.
