From KickApps Documentation
Here's your official technical resource for all of your questions about video on the KickApps platform. If you think something's missing or unaddressed, file a support ticket and let us know.

Video Upload Size Limits
The Video Sharing App allows video uploads of up to 100MB per video file; adding the Pro Video app raises this limit to 1000MB when uploading from the Asset Manager in the Affiliate Center. Members may upload as many videos as they like, and all videos are available nearly instantaneously within the community.
Video Formats Supported
KickApps supports a wide variety of video formats, including the popular .mp4, .flv, .mov, .asf, .avi, .wmv, .mpg, .mpeg, and .3gp formats. (To keep things simple, these are the only ones listed on the member-facing video upload page.)
Encoding Specifications
All videos are encoded to H.264 MP4 files that can be viewed on iDevices, with the following specifications:
- Bitrate: 800kbps 25 frames per second (fps)
- Width: 420px
- Height: Calculated dynamically to preserve the video's native aspect ratio at a width of 420px
- Codec: h264
- Audio codec: AAC
- Audio bitrate: 96kbps
- Audio sample rate: 44.1 mhz Stereo
If the original video is in .flv format, we also pass it through our system to pull thumbnails, but the original video file remains intact at its native quality and dimensions, and is served by default to any device that supports Flash (otherwise, we play the video's MP4 rendition in our HTML player). If you want to preserve the original quality of your video, upload it as an .flv.
Avoid Letterboxing of your Videos
Additionally, if you don't want letter-boxing (black bars around the left and right and/or top and bottom sides of your video, make sure to set your video player's aspect ratio to the aspect ratio of your video (or Auto), and size your video player either at the same dimensions as your video or at dimensions of the same aspect ratio (so for a 16:9 video you'd want a player at 480 x 270px, rather than something like 400 x 300px, as you would for a 4:3). iPhone users, please note that videos taken in portrait mode are encoded sideways.
Flash Player Version
The KickApps video player uses Flash version 10. It delivers video content as progressive downloads by default, and can also be provisioned to deliver live streams in the App Studio. Some compression occurs during the transcoding process, which may affect the image and audio quality. The original video file is stored by KickApps in case it is needed, but it is no longer accessible to you or your community members.
Custom Video Configurations are Supported
Many of these settings can be reconfigured on request. For example, KickApps can integrate with your own CDN or write logo watermarks directly into uploaded videos. Custom configurations are available to affiliates who choose the KickApps Enterprise and ProVideo plans. These plans allows you to run advertisements within your video content (as pre-roll, post-roll, or overlay content).
Search and Tags within Videos
When a user searches videos within your community, the search is actually checking the video's title, description, and tags, (also called the metadata) not the video content itself. Media tags also power the "related" lists that appear alongside every video.
As a community leader, it's important to encourage your members to title and tag videos appropriately so other members can find them within the community and search engines (like Google) can list your videos in their search results, where new people can find you. You can help this process along by editing your community videos' metadata within the Affiliate Center under Manage > Media.
Troubleshooting
Occasionally, videos don't upload successfully. In those cases, you'll typically see a "transcoding failed" status in the Affiliate Center when you view the video in your pending media queue. Typically, videos fail because they are somehow misconfigured or use an audio codec or other specific format that we cannot support. Also note that many video files also have Digital Rights Management (DRM) settings that prevent the KickApps platform from accepting the video.
If you notice any problems, log a support ticket and we'll take a look. Please keep the original copy of the video - we can learn a lot by inspecting the original file.
