We know videos 'should' be 1-2 mins, but our homepage video has many key msgs. At 2.50 mins we're happy with it. Is this ever acceptable?

We've got a lot of 'Why' to cover - a dual network, need to cover different cohorts / geographic considerations / applications of what we do. We've tried to edit it further, but feel like we're just losing key messages. We have a product that needs to be highly engaging for (generally older) consumers as there is a lot to consider / at stake when they commit to it (and probably an entirely new concept, so needs to get across the why - and the what) - it also generally attracts an older demographic who need more reassurance. By reducing it also means difficult to give a 'global' feel which is important too. Can this 'work'? I used to be in the screenwriting business pre-start-up. These rules were fairly tight, but with justification could be extended. Any thoughts very much appreciated. Thanks! PS - we've produced 4 short films... A homepage why / some what =2.50 mins A video for each side of the selected network that gives more detail still and is approx 3.45 An about us video - again, quite long, but users want to know more about us as it's quite a 'product you'd appreciate knowing more about who's behind it' - approx 3.45 mins. (Happy to possibly send if helpful). Hope you can help! Thanks!!!
