Python Script for Video and Audio transcription

I'm looking for a seasoned Python developer with specific experience in video analysis to create a script that can transcribe a full mp4 video and audio into text. Key Requirements: - The script should be able to read a video in mp4, mkv, mov format or a audio (AAC, mp3, ...) - The library used for reading the video is not fixed. You can choose from libraries which should be compatible with both Windows and Linux (and mac) - take a look here: [login to view URL] - The output should detail the (as a class, TranscriptionDetails) ... - file path ... - file name ... - frame number / or location in the video/audio ... - time code / or location in the video/audio ... - the transcription ... - confidence of transcription and should be outputed in a JSON file. The vidoes may have no (0) voices or mutiple person voices (n) Ideal Skillset: - Proficiency in Python - Experience with audio processing libraries - Experience with transcription services processing libraries - Experiences with OOP (classes and lists) - Familiarity with JSON output format. Milestones: MS1: extract transcription of the voices (0..n voices) we will share you testing videos and audios MS2: create a new video based on the json and add the transcription as a overlay to the video Budget? will not be disclosed, place your best bid to get considered Payment? - you estimate in a WBS (optimistic, expected, pessimistic, where optimistic < expected < pessimistic) after getting the task - we discuss about clearances and effort - we mutually agree to effort - we assign you the task after mutually agreed - you provide us a delivery date - you implement, test and deliver - you provide also unit /integration tests to ensure code is always working - you document each required step to make interaction of systems to work - we test on our premise (you maybe help to fix issues) - we pay (basically the rules of freelancer) Closed book vs open book? We work only on open book. Closed book means you are unwilling to define a WBS for the work and you add only a price tag to the task. We are sorry we will not hire you in such a case! Deliveries? - in our on premise git (access will be granted to you) - full sources (NO! Jupyter Notebook) - multiple samples of videos will be shared via URL to download - bash to build & run your code - poetry for libs and version management - libs, need prior confirm and we prefer to use mostly latest stable versions - your code is working on our end too - your code passes our CI build (with provided maven [login to view URL] can be checked) - you may require to help us here on setup - we require, depending on availability and on complexity 2-4 weeks test time per milestone. Usually clearly less
