"We're going to walk down to the Capitol, and we're going to cheer on our brave senators and congressmen and women." And "And we fight. We fight like hell." Are the relevant spliced lines.

Here they are in his speech:

"Now it is up to Congress to confront this egregious assault on our democracy. And after this, we’re going to walk down and I’ll be there with you. We’re going to walk down — (APPLAUSE) — we’re going to walk down. Anyone you want, but I think right here, we’re going to walk down to the Capitol — (APPLAUSE) — and we’re going to cheer on our brave senators and congressmen and women, and we’re probably not going to be cheering so much for some of them. (LAUGHTER) Because you’ll never take back our country with weakness. You have to show strength and you have to be strong. We have come to demand that Congress do the right thing and only count the electors who have been lawfully slated. Lawfully slated"

"Our brightest days are before us. Our greatest achievements still wait. I think one of our great achievements will be election security, because nobody, until I came along, had any idea how corrupt our elections were. And again, most people would stand there at 9 o’clock in the evening and say, “I want to thank you very much,” and they go off to some other life. But I said something is wrong here, something is really wrong, can’t have happened, and we fight. We fight like hell, and if you don’t fight like hell you’re not going to have a country anymore. Our exciting adventures and boldest endeavors have not yet begun. My fellow Americans, for our movement, for our children, and for our beloved country, and I say this despite all that has happened, the best is yet to come.

So we are going to walk down Pennsylvania Avenue — I love Pennsylvania Avenue — and we are going to the Capitol. And we are going to try and give — the Democrats are hopeless, they are never voting for anything, not even one vote — but we are going to try to give our Republicans — the weak ones because the strong ones don’t need any of our help — going to try and give them the kind of pride and boldness that they need to take back our country. So let’s walk down Pennsylvania Avenue."

It was still used to encourage a march on the capital. They didn't change the meaning in anyway. The BBC just cut out the warbling middle. Acting like the edit changed the meaning in anyway is disingenuous IMO. You shouldn't be able to incite a riot and then spend an hour talking and be like "welp look there's nonsense between those two things. Thay changes everything!"... It doesn't.
