Professional Text Removal From Videos

I have eight MP4 video files where I need to completely and professionally remove on-screen text. The text moves from frame to frame, sometimes passing over complex elements or fast-moving elements, and sometimes appearing on simpler backgrounds. Therefore, I rely on your expertise in After Effects (tracking, masking, content-aware fill, or equivalent) to complete the task without any obfuscation or distortion that would reveal the editing.

Before we finalize the agreement, I will send you a short sample of each video so you can see for yourself that clean removal is possible. After reviewing it, I need to know the total price for the eight videos and the timeframe required. My priorities for the final result are:

• That no trace of the removed text remains, even when paused on any frame.
• That the motion accuracy and original image quality are maintained (same encoding and size).
• That each video is delivered ready for review, followed by the final version after any minor adjustments.

If you have experience with Mocha, Rotobrush, or similar tools for precise element tracking, please mention this in your response, along with examples of previous work removing text or elements from animated footage. I'm looking forward to a clean work that looks as if the words never existed.
