Strip Text From Educational Videos

I need clean, text-free versions of several educational videos. Each file currently contains an intro title card plus hard-coded subtitles that must be completely removed without lowering visual quality or altering the original resolution and frame rate. Some files may come with titles or subtitles on a separate layer, others may have them embedded—I will supply whatever source materials I have. Your workflow can involve Adobe Premiere, After Effects, DaVinci Resolve, or any comparable software; what matters is a seamless result that shows no traces of the original text and keeps the audio perfectly in sync. Deliverables • A processed video for every source file, identical codec and dimensions, with all titles and subtitles gone • Brief note on the method used, so I can replicate the approach on future content if needed Please keep naming conventions unchanged aside from a “_clean” suffix, and send back the finished files via the same cloud folder where you pick up the originals.
