I'm going to start making assorted ball review videos.  I know what I would consider to be the most important and/or relevant information, but I was wondering what other people find the most helpful. 

First of all, these videos are mainly going to be aimed at my local community.  The reason is to provide them information on what we have on the shop that they can view at home to make their decision time quicker and easier and expedite the actual in-shop process as much as possible.  Here is how I plan the different videos to go:

For balls we don't stock: A picture of the ball and tech specs will be the only video content, though I'll record my personal review and opinions and explain how the ball will react for strokers, tweeners, and crankers at each of our two different houses, and then expand on what condition(s) that ball would be ideal for in case they're considering it for tournaments.  For EVERY video I will also provide several links to other review videos in the description.

For balls we DO stock: I'll sit down with the ball and a tech spec sheet and do just about the same as I would for balls we don't stock, I'll just have the actual ball sitting there so they can see how it differs from the stock photo.

For balls I own: I'll do all the same as the other videos plus include several shots of me throwing the ball. 

I know it's hard to know what to suggest being that I haven't put one out yet.  With so many review videos already out there, I realize making my own may sound needless, but other pro shop guys should agree that something I/we hear constantly is "well that guy on the video is a cranker," or "sure that ball looks good on the video, they set it up that way," or "I don't think that ball will work for me like it does for the guy in the video."  My purpose is to address all these questions specifically for my local community, but if there's anything additional I can add that would make them helpful to a wider range of people, I'd definitely like to do that.  Some people still do get a lot out of watching the videos from Buddies, Bowlers Deals, etc, (I know I do) so that's why I'll still be adding links to those videos in the description.  Also, I've got buddies and coworkers on staff with various different companies, so even if I'm not throwing the ball I'm going to try to get as many actual reaction videos as I can. 

Yeah I'm not going to try to sell every ball as something somebody needs . . take the Sinister for example.  Great ball, really looking forward to it coming out.  Would anybody need it for the league shots around here?  Not very many, and I'm going to make sure I point that out.  But would it be a great ball for Nationals or fresh oil at the Greater Ozarks?  For a lot of people it sure would.  Going to try to sneak little tidbits of information in there too.  Most of the time when people say they want a ball that hooks, they mean they want a ball that gets down the lane and turns sideways.  Hope to help people learn better what they want and how to get it. 

I can't understand what they are saying but I like the format for showing a ball that ABSbowling uses:

something i've often wish people would do with ball review videos, is

1 - show how the ball reacts on fresh oil vs lanes that have 30 games on them...

2- if its just you in the video, record a full 3 to 6 game set of all of your shots and then post up your scores from bowling on X sport shot.... Cuz watching someones video review and its nothing but strike shots is laughable.... i mean i could make a video 5 mins long of me doing nothing but striking on the US Open pattern if i threw enough shots....

3-  if you have X ball, and its purpose is for you to play up the boards or where ever on the lanes, then play there.... i've seen too many videos where someone just has a ball drilled up with their typical layout and on a house pattern it does the same damn thing as every other ball they have reviewed...

I like this....it's like "the things that P*&s me off abotu bowling videos are" vent, lol. So well here I go:
 
Show the ball on something other than a house shot. I know you are making this for your local customer, and maybe a house shot is all they will see, but every ball will look almost the same on the house shot. The best would be as someone else suggested, show it on a house shot, show it on a sport shot, show it on a high volume shot, etc and make sure you tell everyone what the shot is.
 
Show more than just strikes. Show how the ball reacts on shots it may not be right for. Like the Sinister you mentioned, throw it on the THS shot and show it going dead left, or show it burning up and not hooking and explain what they are seeing. Show a meduim/Light oil ball on the high volume pattern going dead straight. Explain why the ball is not right for the pattern. This will go a long way to help your customers determine which ball might be best for what they see.
 
Those are two of my pet peeves. I think others have mentioned the rest. It possible, and this is a stretch I know, besides showing a cranker, tweener, stroker breakdown.....maybe have guys with different tilts as well. A tweener with high tilt will see a different reaction than one with lower tilt, etc. I tend to be more up the back so I tend to see slightly different to sometime significant different reactions than others around my same speed and rev rate. Again this is probably very hard to do, to find people so different, but if possible it will add another nuance to your vids and help people pick and choose equipment for themselves even better.

The last thing you want to do is show a ball going straight.
