Long post incoming but I need to get this off my chest. Over the years people have been yelling at Phil to edit his playthroughs and make the parts longer to increase watch time and ad revenue. But a lot of people (Phil included) Don't understand how watch time works.
in 2012 YouTube noticed that a lot of videos were getting a lot of views because of click bait. Naturally these videos had people click away immediately but these videos were getting featured because of the current algorithm. That's when they started featuring videos based on watch time. Overall watch time is calculated by a very simple formula. Views x average view duration. If you want to increase watch time you either need to get more people watching or get them watching for longer. Ideally you want to do both.
I've seen many different opinions regarding the best way to get people watching for longer. Some say make the videos longer and other say make it them shorter. Here's my opinion. It doesn't matter. I'm not positive on this but when It comes watch time I think YouTube ranks your video against other that are the same length. In other words making your 3 minute IGN review into a 30 minute Angry Joe review doesn't give you an edge of 3 minute videos. And if you extend your video without giving it extra content it will drag on and people will skip ahead or worst case scenario leave and never come back. You now have a 30 minute video that people watch less of and you'll be going up against 30 minute videos that are concise because they have more to talk about than you.
In short the secret to good watch? Make good content that people will want to watch. And they keep making videos. You can make a 30 minute review or you can make 10, 3 minute reviews It's the same result if you can keep people watching.
Watch time and video length is even more irrelevant when it comes to Phil. Let's face it. Phil's actual videos are his live streams. Splitting them into parts doesn't increase watch time. Yes views increase but that doesn't mean more people are watching. Notice how the first part of a playthrough has more views then the rest? That's an example of the low attention span. The truth his that Phil's playthroughs bring in 10,000 unique viewers and only a few 1000 actually watch it.
So Phil making videos shorter literally does nothing to help you. Same with making them longer. The only way to increase your watch time is to record more. and you're already doing 4-6 hours of gameplay streams a day. So I'd say the way you do things is just fine the way it is.
However. I have to say that the best coarse of action is too make your videos longer and for one simply reason. Inbox spam. And no. There is no way to prevent it. There was a feature to create subscription folders. For example I could have a sub box for your playthroughs and one for other let's players, and one for music. YouTube removed that feature. But even then that doesn't prevent it. Because I'm still presented with 20+ videos in my face. Same thing if I go to your channel. Do you have any idea how annoying it is to scroll though 200 videos to get to the halfway point of Persona 5?
IMO a video on YouTube should have a beginning, middle, and end to be complete. For example, one video for chapter of the game or a boss fight. But with your style we get 8 parts for exploring mementos and a full part of discussing what to do next. Sorry for being rude but that last part is a garbage video. literally no context or progression. It's not about the video length. It's about making a complete video.
And for my last point. Editing. Going to be honest here. Whoever told you to you need to make highlights is an idiot. I mean there's nothing wrong with highlights. It's a great way to keep people entertained without having them dedicate hours to get to the part they like. But it's missing the context.
And guess what? Other people who do playthroughs DON'T do that! Their playthroughs show the whole game and then they may make a montage that's separate for fan service. TheRadBrad, ZackScottGames, Hell even PewDiePie. I watch some of their playthroughs. and there was almost never a jump cut. There were exceptions of coarse. For example PewDiePie got lost in the beginning of Resident Evil 7 as he didn't see the side path and ended up going back the way he came. So he fast-forwarded slightly. Don't forget that most live streamers archive their streams on YouTube. No editing what so ever.
However, my issue isn't that your videos show the whole game. That's good and normal. My issue is you are staunchly against editing your videos.
This for example. I'm mean sure the short video was an honest mistake but how hard is it to open an editor and clip it together with part 16 or 17? 5 minutes plus rending time? This is another example of a garbage video where nothing happens. So why did you even bother uploading it in this state.
I have 2 suggestions.
1) Release the full stream with pre-stream and breaks cut out as one video with multiple ad breaks
2) Record the full stream and then split it in the editor so that each part covers a segment of the game.
I'll use Resident Evil as an example:
Jack Garage Boss Fight
Jack Boss fight
Marguerite Boss Fight
Bee House Attic
Back to the Mansion
Jack Boss fight
The Ship Part 2
So basically what I want to say is that there is nothing wrong with how you do things. All you need to do is make the videos more complete (Short or long) and not worry for editing except for technical difficulties and excessive parts with no progression. For example, black mesa, Batman Arkham Asylum or the Secret of Monkey Island.
