-5C and above is doable, at least for me, but it is neither fun nor effective if it is colder
That was my cut-off too! Agree it gets hard when it is colder - especially if you are in a real winter zone where there will be snow and ice at sub zero temps.
Indoors I :
+ setup the trainer near a big window so you can see outside.
+ have an industrial fan for cooling.
+ really good headphones to cancel background noise and zone into both the music and your effort.
+ have a ride-plan that breaks up the session into small chunks (even if you aren't doing intervals and just going easy).
I couldn't ever get into watching videos... I dunno why. Maybe it was because I always chunked up the ride even if it was easy.
The trainer is boring - so breaking it up into small chunks really helps. If you're going easy you can do simple things like vary your cadence, isolated leg exercises, work on how you carry your upper body etc. There is always something with your riding form - or an interval you can focus on for 1-20mins stretches to break up the ride. That and the music makes the time pass ok.
I can't just jump on the trainer in the fall and start banging off big rides. I work into it by starting with 20-30min sessions 2-3 times a week. If you just jump on and bang out 90mins you can drive yourself crazy... but you can work up to 90-120mins in smaller bits without it always feeling that it is so mind-numbingly boring.
I had a coach who once told me to finish a winter cross training workout with a ride on the trainer. I found that to be a really effective work out. I'm lucky to have xc ski trails or bushwacking ski/snow shoeing really close to home. I'd setup the trainer so when I got in from a 2-3hr ski or snow shoe I could change and be on the trainer in 5mins--then tap out a 60-90min trainer ride. I can literally ski or snow shoe right from home, so I could get in a near continuous workout. If I want to skate ski or classic ski on groomed trails I'm just a 7 min car drive from a trail-head.
If you need to (or god forbid want to do) a long trainer workout - 120min or more -- I find it helpful to get off in the middle and take a short break, drink, stretch and
CHANGE YOUR SHORTS (especially if you sweat alot). Its amazing how putting on a fresh pair of shorts makes you feel ... totally fresh again.
