1. Visualize it in your head - You need to know how you want it to look like, not just put random clips, song you found and boom! No, you need to have a plan.
2. Quality - This is purely subjective but most people would rather have a clip of you fighting at 800x600 and 60 fps rather than 1080p 30 fps, smoothness is key there, but don't sacrafice quality entirely for that.
3. Clips and their unique aspect - Avoid using simple clips with no effort such as /1v1 arena clips or targetting very weak players, It makes things painful to watch, doesn't showcase your skill very much.
4. Editing aspect - Do not overedit, unless you have actual purpose, calm down with intense effects, your montage has to be watchable It's meant to showcase your GAME skill not EDITING skill.
5. Songs etc - Try to avoid using songs with long intros or hooks, get one with smooth flow and not too long (Montages usually should be 2-3 mintues depending on clips and lenght of them)
6. Promotion - Your skill promotes you, not how many shitty montages you can make.
This is example of a poorly made montage but with not the worst clips (I purposely make shitty montages out of leftovers, unlike you fucks)
Anyways montage soon (This time for real)
