Video hosting and mashup solution SplashCast is launching an upgrade to their video player tomorrow morning. The most noticeable change is a new YouTube-ish playlist of video thumbnails in the bottom 20 percent of the viewer, which can be pulled up and dismissed at the user's discretion. Previously, users were limited to a channel-view text list (which is still available), but my bet is that users will feel at home with this newer navigation.
The real killer application, however, is the inline commenting system which gives users three ways to leave their feedback: a video clip (from a Webcam or hard drive), text, and voice. All three remain in the same section, and there's no user registration required to leave your two cents. Recording and playing video in the player is really simple, and looks pretty good.
There are a few other mentionable tweaks, including a pause button, an inline "e-mail this" tool to share show segments or entire programs with friends, and a full screen button that remains no matter what type of program you're viewing (not just videos and photos). There's also a new "follow me" button which lets you know when the program's creator publishes new shows. It's a little bit like the channel-creator subscriptions with YouTube.
SplashCast is planning to introduce a mobile upload feature to its platform within a month, so users will be able to drop photos and video clips into their channels from a mobile phone--a lot like Kyte.tv (review). There will also be more celebrity channels, and the potential for Twitter integration and live user chat, similar to Pikspot's player.
