I have a new batch of squash recordings—more than five complete matches, running a total of roughly 30-60 minutes—that now need precise, frame-level ball tracking. You will receive the original MP4 files together with a minimal JSON schema; each frame must contain the ball’s position recorded as a bounding box, since that is my preferred format for this dataset. Feel free to work in CVAT, VIA, V7, or any comparable modern annotation platform. Automated interpolation is absolutely welcome, but whenever the tracker drifts or loses the ball I expect manual corrections so the marker stays locked on every frame from serve through the end of each rally. When I play the footage back with the overlay, there should be no visible lag, jump, or disappearance. Deliverables • One JSON file per video, perfectly matching the provided schema • Output that re-imports cleanly into my pipeline and visually follows the ball without drift Once the files pass that simple playback check, the job is complete.

Hello! I’m interested in your squash ball tracking project. I have experience working with CVAT on AI annotation and tracking tasks, including object labeling, interpolation, and frame-by-frame corrections. Most of my experience was working inside client/company CVAT accounts where projects and datasets were already configured, so I’m very familiar with the annotation workflow and tracking process itself. I understand the importance of accurate tracking without drift, especially for fast-moving objects like sports balls. I can manually correct frames when needed and ensure consistent tracking throughout the video. I’m also comfortable working with MP4 files, bounding boxes, and JSON annotation formats, and I can adapt to your provided schema. I’d be happy to review a sample video and discuss the workflow details. Best regards, Iryna Vesnina

Hi... judging from your description, it seems like this is about video annotation and the use of pins and labeling annotation boxes as tools... I've used CVAT several times. I'm used to the SUPA platform, Labelit, labelmee, and even Robolabel... I have a question if we're working as a team... Is this rate per actual work hour? Or is it just per hour of your annotated video, which totals 1 hour (60 minutes)?
