"Yamato 2199: A Voyage to Remember" is the recap film yes. It is more or less a highlight/plot reel for those that never saw the series. There is very little character development, as most of the character moments are not in the film. There is a small amount of new footage. Almost all of it is during the Rainbow Star Cluster Battle, with a tiny change at the end that is there because the plot points what lead to the original scene were not included, so it wouldn't make sense if the scene was shown as orignially made. The film covers what is considered important for the plot or possibly things that will be needed to know for the next film/future series.
The special feature do not have subtitles. However they do cover some of the scenes not seen in the film, including the one changed scene. (the change is basically what clothing Yuki Mori is wearing at the end).
I will say that the film's story only really covers between episode 1 - 24, with 26 only touched on in the credits. This makes some sense given that the next film "Ark of the Stars" will start pretty much as they leave Iscandar, so that will likely cover the film's events and episodes 25 and 26. That film comes out in two weeks in Japan. I expect the BD to come out in late January.
They did finally show how the Comso Falcon's get back into the hanger.
I'm really curious what happened there.
