I'm thinking about doing more videos, not only screencasts of rounds. For some time now I'm using OI Checklist by Rezwan.Arefin01 (cannot recommend enough, especially if you are preparing for hard IOI-style contests) as an archive, so I'm thinking about doing videos with editorials (more like my thinking process) for some old POI problems.

So, here are some questions for you:
1. Is this interesting?
2. Should I read (and think about) problems beforehand? Pros: I will have more structured thoughts about problem, I will know for sure if I will be able to solve this problem in a short time, ??? Cons: It is kinda unfair, it may look like I'm crushing it when in reality it could take hours for me to solve, ???
3. Should I do one-problem length videos? The problem is that I prefer to open some (3-6) problems, read all of them, and then think about each problem for some time, probably starting with the one I liked more.
4. Despite these are OI-style problems with partial scoring I'm trying to go for a full solution, most of the time ignoring groups. Sometimes full solution of these problems are really-really hard. Should I do groups always, or only when I'm stuck for long time, or other options?
5. Do you have any suggestions about what kinds of videos I should make? Or other things I didn't think about concerning this particular kind?

UPD
Thanks for your input! I thought a bit myself and here is my current position:
I'm willing to invest some time to learn basic video editing (yeah, didn't do anything before, just recording screencasts), I hope that I will even add some things to screencasts in post. This way I can read some problems, then solve them one-by-one, but make separate videos for each problem. Mostly I will do "blind" attempts at problems, since most of your want to see me struggle :) I will go through groups if they are interesting, but rarely will implement partial solutions.
About lectures and lower-level educational videos: don't think so at least for now because it is not interesting for me.
Because of learning basic video editing I will be slower at first, but I hope to do first video in next few days, so stay tuned! Also later today I will upload USACO Platinum screencast, so you can watch this if you are interested.
