Menu „Zuschneiden“:
„Zuschneiden“ is normally used in the context of craft for cutting wood, textile, paper, or the like.
I’d use „Trimmen“ instead.
„Zuschnittmodus“ in particular rather suggests cropping, not trimming.
Better use „Trimm-Modus“ and "Dynamischer Trimm-Modus“
Further down, I’d use accordingly:
„Trimm-Anfang“, „Trimm-Ende“, and „Bis zur Auswahl trimmen"

„Klingenmodus“ suggests a sound, rather use „Messer“ or "Rasierklinge“, „Modus" is not needed here.
(While „Klinge“ is a correct translation for blade, "Klingen“ is also sounding, so a bit misleading.)

"Trimm-Editor“ for the new feature.

Now, „Nächsten“ is tricky, since we don’t have two words in German for nearest and next, so it’s ambiguous, both for location or time.
I don’t have a better solution, since „nächstliegend“ would be clearer, but too long. Let’s leave it as is.

I like that you added an explanation for Slip. Maybe do the same for slide? „ Slide – Clip verschieben“

„Verrücken“ is normally used for heavy objects like furniture, What about "Versetzen“ for nudge?

„Skalieren“ is normally used for size, but not for duration. What about „Länge ändern“ ?
You are using that for „Länge anpassen“ right below.

Finally, „Fade to Playhead“ is a bit misleading even in English. What about „Abblende vom Abspielkopf“, since it goes forward?

For the submenu „Auge verschieben“ one could also use „Auge versetzen“.
„Gegenauge" is quite strange, though.
What about „Anderes Auge einen Frame nach links“ und „ … nach rechts“? If that's too long, change the gender of all occurrences of frame.
„Anderes Auge ein Frame nach links“ etc. that fits the length.
