Got a Tim Grose video on my recommended feed yesterday. As I know he frequents these boards, I have a piece of unsolicited advice that may nevertheless be useful:
The video was called 'my fastest 5k for years' and the graphic showed the Brooms were running. I was expecting some race footage and to follow along- would you beat the Brooms? What time would you run? What was the course like? However, much to my dismay the video started with one of those 'spoiler montages' that show the whole content of the video in a series of short clips before it's actually happened (this editing style reminds me of 2012-era Channel 4; Kitchen Nightmares etc. used to do it all the time, made watching the show pointless because you'd already been shown all the highlights).
Within 33 seconds you had already confirmed that you had beaten the Brooms and run 18:38, before the race footage even started. So I stopped watching. Why would I need to continue? You can check your youtube analytics to see if a lot of other viewers also stopped watching after 33 seconds and that might inform your editing process in future; it might just be me that has an issue. Not having a go- I'm sure the video was good but I'm just explaining what led one 'recommended viewer' to stop on this occasion.
