## Description

Point at the exact frame.<br><br>No more “around 1:23, the hand looks a bit…”. Hello Feedback lets you stop video, images and PDFs on any frame, leave notes and drawings right there, and hand off a note PDF or PNG. On a tablet you draw with a pen and scrub with your finger.<br><br>Made for animators and directors, editors and producers, storyboard artists, teachers and reviewers — anyone whose feedback is hard to put into words.<br><br>■ Open<br>• Video: mp4, mov, mkv, webm (H.264, HEVC, VP9)<br>• Image sequences — several images as one set, one frame each<br>• Storyboard and design PDFs — one page per frame<br>• No server, no account, no upload<br><br>■ Exact frames<br>• Step frame by frame and the frame number always matches the picture<br>• Fractional FPS such as 23.976 and 29.97, frame offset (start at 1001)<br>• 0.25× to 8× speed, loop, ping-pong or play once, In/Out range loop<br>• Drag a finger across the picture to scrub<br><br>■ Notes and drawings<br>• A text note and thumbnail card on any frame, five label colours<br>• Bookmarks, and step playback that shows only the noted frames in real timing<br>• Pen, arrow, box, text label, eraser, and a laser pointer that is never saved<br>• Hold drawings over several frames, a background layer under every frame, copy and paste between frames<br>• Pen pressure changes the line width, and your palm is ignored while you use a pen<br><br>■ Compare and view<br>• Onion skin — previous frames in red, next frames in green, to check spacing and arcs<br>• Annotation ghosting — see the strokes from neighbouring notes<br>• A/B compare — two versions side by side, stacked, overlaid or with a wipe<br>• Zoom, pan, rotate, flip, rule-of-thirds, center and safe-area guides, full screen<br><br>■ Hand off<br>• Note PDF — one page for every frame that has a note<br>• PNG — full-resolution capture with your drawings<br>• Notes JSON — notes, drawings, ranges and FPS in one file, to continue on another device<br><br>■ Library<br>• No save button. Notes save automatically and come back when you reopen the same file<br>• Group by project; if you moved a file, relink it once and the notes follow<br><br>■ Your work stays on your device<br>• No internet connection needed, and no data is collected<br>• No account, no ads, no subscription. Buy once and keep it<br><br>Editing codecs such as ProRes and DNxHD are not supported; please convert to H.264 mp4.<br>For Android tablets.<br><br>Contact: contact@studioroomkr.com
