  • Dealing With Game Footage
    I've used annotate.tv to timestamp youtube videos & comment on whatever's happening. Best is to just watch with your teammates over discord or something though. Source: about 4 years ago
  • Is there an app to take notes in videos?
    Maybe your best bet is to upload to YouTube as unlisted and use https://annotate.tv … on iOS I use KMPlayer to add markers (boorkmarks) and use those to annotate once back home. Wish there was something better. Source: over 4 years ago
  • Sharing Articles to Obsidian?
    I use Inoreader, raindrop and hypothesis. I'm trying annotate.tv extension in chrome for youtube videos. Everything syncs to readwise and so into obsidian. Source: about 5 years ago
