I've been an exclusive user for Tricaster systems for both SD and HD productions in the past. But Vmix is a huge game changer from my 2 days with the system. Good on you for finding a need and filling it air-tight.
Your system is currently very kind to low grade computers for SD (and I can only imagine, just as kind to mid grade for HD)
If you do implement a "multi-view delay" I have a few suggestions:
1) Don't replace the current delay set-up. So one could still have separate delays running to save on HDD space (Trying to incorporate Vmix into hockey rink that I do work for)
This is HUGE for unmanned wide angle goal cameras, to have them with a 30 second replay while the other cameras get what they need)
2) Assuming the user does: add input --> Multi-view delay and configures it much like the multi-view screen i've seen (simple drag operation) perhaps it creates a preview "block" of cameras that you can select from: Premiere CS 5+ and FCP 6+ have had this feature. See
for a decent example. (not me- never seen this video before. Just has a good show of how it would work)
The only difference between Vmix and the premiere version (sourced above) would be the slider that is already in the software for playback speed control- and there are no "do overs" This could be done on the fly to play important plays in sports from multiple angles. In hockey it would be something like -- Wide shot of the ice -cut to- behind the net showing the forward breaking away -cut to- the same wide shot has zoomed in on the play and shows more detail -cut to and decrease speed to 33%- behind the net shot showing the puck going in the net.
3) An
amazing addition (somewhat hinted at by the OP) is the inclusion of metadata. I'm no engineer and have no idea how difficult this would be. But to be able to write notes on the clips as they are captured- (I'm focused on the title of the clip . Whenever I delay out of the SD version of vMix it auto labels the clip as date time etc.)
Here is an example of a meltdown feature through ZePlay ($7,500 for a 4 in 4 out HD-SDI model)
So back in vMix- this could operate like this:
When you have created a clip and are replaying it or have paused it, you have a little window at the bottom to label the clip name at any time- until you hit "save" at which point it saves the MPEG-4 to HDD.
Reasoning: If everything goes my way at the Ice Rink, we will be webcasting 2 high level youth hockey teams using vMix as our exclusive SD platform. From these games, I can save the footage (Name each goal #8 Goal. etc) store the footage on a server. then come back to it near the end of the season. I can then approach each player individually and offer to cut a highlight reel of the entire season for $XYZ.99 -- If the clips are already named from vMix, it doesn't take much filtering to get EVERY clip of #8 team A in to my premiere CC editor and cut them together with filters so they can try to draft in to the pro-leagues. This money made can then be piped back into the program, to buy the upgraded SD version, or even the HD version + Cameras for the rink.
I've seen many secondary school (high school) football players (huge sport in Texas, USA) pay upwards of $3,000 USD to get a highlight reel of several of their games. With vMix, you could undercut any other bid and deliver a superior product because you aren't ISOing the footage, nor are you wading amidst MANY replays like in the Tricaster's time-warp system (i've tried that before. It was a
nightmare going from MVI 001 - MVI 999 to try and find every touchdown.
Just my two cents.
Great software and I look forward to getting a key soon! -- Side-note I JUST missed the free HD possibility with studiotechlive by a week--- This would have been my entry for an HD key.
