Here are my two cents: It sounds like she has an awful lot going for her. For keepers, height is an issue, but obviously not the only issue.
Getting a few ID Camps under the belt early is not a bad idea. I would start at a small, local camp so that your daughter gets used to the stress of the meat market without any potential adverse consequences. And when you do go to the camps, ask yourself not how well your daughter did, but what percentage of girls attending could NOT make a college team somewhere. Usually, there is a good bit of quality to go around.
That is why when your daughter is a year older she needs to have made relationships (via email and face to face meetings with coaches before she attends the camps.
Game video has the advantage of showing the quality or level of play of the entire team and opponent, which is helpful. It may also show strategic knowledge, such as distribution skills. However, as noted, it takes quite a bit of time to gather enough video and to edit the tapes. Do NOT send the tape of an entire game. If you can invest in it, I would buy a HD video camera and a tripod, fix the camera on your daughter and just enjoy the game.
A skills video may be the best starting point, as it shows intangibles that may not come out with single saves on game tape. For example, repetitive quickness, jumping height, and natural ability may be better shown on a skills tape. If your daughter has a keeper trainer, I would discuss it with him/her.
Better yet, consider that as a topic in introductory emails to coaches. Eg., “I have some skills tapes and have started work on game tapes. Which would you prefer seeing?”
Just remember, it is way better to start early than to start late.
