It looks like the entire OP has been translated in this article. It says that the lines are from 2 different EF related songs, "Eternal Feather" from the ending theme of the last episode of "ef - a tale of memories" and "Emotional Flutter" from the opening of the game "ef - a latter tale".
The article has all of the text, side-by-side, with the English translation and (in red) the song that the line came from. There's also a note at the end about some names of other EF related songs on-screen.
Holding the reviving memories [Eternal Feather]
To my chest [Eternal Feather]
There was a distant sky on the other side of the window [Eternal Feather]
I was watching the unreachable clouds [Eternal Feather]
The smile left behind on the road home, [Emotional Flutter]
Will never find the voice it looks for [Emotional Flutter]
The darkness engraved in my memories [Emotional Flutter]
Even now, won't end [Emotional Flutter]
Even now, won't end [Emotional Flutter]
Swooping down from the sky, [Emotional Flutter]
There was a distant sky on the other side of the window [Eternal Feather]
I was watching the unreachable clouds [Eternal Feather]
My breaking heart has been healed [Eternal Feather]
I heard a tender voice [Eternal Feather]
Pieces of a dream spill and fall into my palms [Eternal Feather]
To search for the lost answer, I start running [Eternal Feather]
Overcoming the time when we came across each other [Eternal Feather]
Our hands join together [Eternal Feather]
Holding the reviving memories [Eternal Feather]
To my chest [Eternal Feather]
I search for your back that I have forgotten about [Eternal Feather]
Making the loneliness end [Eternal Feather]
I believe you, but I feel uneasy [Eternal Feather]
And I dreamed of your voice [Eternal Feather]
I fear getting hurt [Eternal Feather]
and make my face smile, [Eternal Feather]
I'll start weaving a breakable courage, if we're together [Eternal Feather]
When I change even the pain frozen onto me into warmth [Eternal Feather]
The sound of the bell echoes [Eternal Feather]
Into the endless future [Eternal Feather]
Soar up high into the sky [Eternal Feather]
Even if you don't have feathers [Eternal Feather]
I believe you, but I feel uneasy [Eternal Feather]
And I dreamed of your voice [Eternal Feather]
The smile left behind on the road home [Emotional Flutter]
Will never find the voice it looks for [Emotional Flutter]
The darkness engraved in my memories even now, won't end [Emotional Flutter]
Even now, won't end [Emotional Flutter]
Swooping down from the sky, [Emotional Flutter]
The white wings swayed [Emotional Flutter]
Running with my outstretched hand, [Emotional Flutter]
I chased after your shadow [Emotional Flutter]
If the falling white snow were to pile up, [Emotional Flutter]
It would cover up these sad colors [Emotional Flutter]
The love sleeping deep within my heart [Emotional Flutter]
Please remember it [Emotional Flutter]
Soar high up in the sky [Emotional Flutter]
And spread your wings [Emotional Flutter]
Inside the gentle rays of the sun [Emotional Flutter]
You showed me your dreams [Emotional Flutter]
Fluttering down from the high sky, [Emotional Flutter]
Wear your white wings [Emotional Flutter]
Our joined hands [Emotional Flutter]
Won't let go of the future [Emotional Flutter]
The love sleeping deep within my heart [Emotional Flutter]
Please remember it [Emotional Flutter]
The smile left behind on the road home [Emotional Flutter]
Will never find the voice it looks for [Emotional Flutter]
The darkness engraved in my memories even now, won't end [Emotional Flutter]
Even now, won't end [Emotional Flutter]
There was a distant sky on the other side of the window [Eternal Feather]
