It w= ill read in the recording and use speech to text to create a transcription.= You can then edit the transcript as if you are working in a word editor. R= emoving a line will remove the audio and video of that portion. In addition= , you can use filters (noise canceling etc) to improve sound quality. I hav= e used this a year ago for some podcast recordings and it worked well. Not = sure how the software developed in the meantime. I don't have the paid vers= ion anymore. You pay for the file size so video editing will be much more e= xpensive than audio-only editing. In what language did you record? It doesn= 't support all languages yet. Also my accent in English introduced many tra= nscription errors.
