▸case-23 I am adding a video file to my project and speeding it up to 2.0x. Standard HTML5 <video> elements distort audio pitch or drop frames during exporting. What component handles off-thread frame decoding and pitch control? | fail→pass | — | — | — | — | — | — | — | — | — | — | — | — |
▸case-14 I need to get the pixel dimensions of a rendered container in a video scene to position an arrow graphic next to it. Should I attach a resize observer to window or use a layout measurement helper? | fail→fail | — | — | — | — | — | — | — | — | — | — | — | — |
▸case-16 I have three consecutive callout boxes in a video. I am thinking of using frame index comparisons like frame >= 30 and frame < 90 to manually mount each callout. What timeline structure component should be used instead of raw frame math conditionals? | fail→fail | — | — | — | — | — | — | — | — | — | — | — | — |
▸case-22 I have an inner animation component that takes 100 frames to play, but I want to crop it so only frames 25 through 75 are rendered on the timeline. What timeline wrapper pattern trims the beginning and end of a component's timeline? | fail→fail | — | — | — | — | — | — | — | — | — | — | — | — |
▸case-24 I am configuring the root file of a video project where multiple dynamic compositions are registered with fixed frame rates, dimensions, and dynamic props. How are compositions declared at the root level? | fail→fail | — | — | — | — | — | — | — | — | — | — | — | — |
▸case-21 I want to slide Scene A out to the left while sliding Scene B in from the right over 15 frames. Should I manually calculate overlapping offsets in two Sequence blocks or use a transition composition component? | fail→fail | — | — | — | — | — | — | — | — | — | — | — | — |
▸case-20 I have a podcast audio file and want to generate timestamped captions automatically without manually building SRT files. What package or workflow converts speech to word-level timed captions for compositions? | fail→fail | — | — | — | — | — | — | — | — | — | — | — | — |
▸case-02 I need to dynamically calculate a Remotion composition's total duration and dimensions based on an incoming video asset's properties. How do I inspect the media file's duration/resolution and feed those into dynamic metadata props? Provide code snippets showing the recommended setup. | fail→fail | — | — | — | — | — | — | — | — | — | — | — | — |
▸case-03 I am writing a Node.js backend service that converts incoming MP4 video uploads to HLS format (.m3u8) using fluent-ffmpeg. How should I set up the ffmpeg command pipeline in Node.js to generate multiple bitrate variants? | fail→fail | — | — | — | — | — | — | — | — | — | — | — | — |
▸case-09 I need to extract frame snapshots as images from a video asset at specific timestamps before assembling the composition. Should I canvas.drawImage in a hidden video loop or use a media extraction library? | fail→fail | — | — | — | — | — | — | — | — | — | — | — | — |

▸case-11 I am adding an animated GIF overlay to my composition. Standard <img> tags cause the GIF to loop asynchronously based on browser timing rather than video frame numbers. How should animated GIFs be embedded to guarantee frame-level frame locking? | fail→pass | — | — | — | — | — | — | — | — | — | — | — | — |
▸case-12 I want to display a Lottie animation file that steps forward frame-by-frame with the video timeline. Should I use the standard react-lottie player package or a timeline-synchronized wrapper? | fail→pass | — | — | — | — | — | — | — | — | — | — | — | — |
