It's hard to please a TF2 audience with fragvids because most people are used to minimal edit fragclips like the frag clips thread. I am also biased towards that so that's why my feedback is the way it is. Perhaps I'm totally not your target audience which is obviously fine. You can't please everyone.
I also don't have much experience editing myself. This is from a viewer perspective.
You need a balance (imo) of:
-editing
-gameplay
-context
In edits like this it is obviously fine to lose gameplay and context for the sake of your edit. Though overall you still need to find a balance
clip 1: You don't have to show the full clip, but seeing how the soldier ended up airborne from the demoman's POV adds context to it and I'm also personally a fan of seeing 'how' people aim so having it shown from the demo's POV covers both of these things.
(Editing fine. Not enough Context. Not enough Gameplay)
clip 2: The editing itself is fine imo. Kind of a confusing play because nothing indicates the viewer why the medic was low and dies to 1 pipe but that's not an editing issue. With fast paced editing this probably isn't easy to fix because you'd have to show the viewer why the medic was hurt which might've been 10 seconds ago
(Editing fine. Enough Gameplay. Some Context missing but possibly hard to fix)
clip 3: Biggest offender with the whole gameplay thing. It skips the actual shots. With good reason obviously, you're syncing with the music. But the gameplay itself is lost, then the inbetween of running to the tiny pack is regular speed, then it syncs the shots again. Feels awkward. There's other ways to sync without losing the gameplay. Showing the gameplay, then using the small pause where the scout goes for the pack to do the syncs with some smooths that you cut/transition between. Even if you still want to sync the shots, the regular speed where the scout runs for the pack feels off and probably needs a smooth or something to take its place. Just feels awkward to go back and forth between the sync shots and walking in a straight line at a wall
(Awkward edit. No gameplay. Context isn't really required for this clip, just a flank play 3k)
clip 4: Fine for gameplay. Not sure why you show the stickybomb launcher reload after the shot. I'd just use the no viewmodel POV you have going on in other clips. Also not sure why you'd mirror the viewmodel. Seems kinda redundant
(Some awkward editing elements but overall fine. Gameplay fine. No context needed, just a nice pipe)
clip 5 & 6: These are fine. But obviously this is viewed from my point of view and these 2 clips have a lot of gameplay to them and less editing than the other clips. As I've mentioned before I'm used to minimal editing
clip 7: I'd show a smooth of the medic pushing the choke before the pipe is fired. Also not sure why one pipe killed the medic. Was there also a sticky trap? A teammate suiciding? If so make sure it's visible in the smooth. Need that context
(Editing fine. Gameplay fine. Context missing)
