SANJIESAN CREATOR / Timing exercises
Check where a short loop returns to its beginning
A short movement can look acceptable once and feel abrupt when repeated. The last-to-first transition is part of the design, even when it sits outside the portion you normally watch while editing. Give that boundary its own review before decorating the motion.
Mark the intended playback range
Identify the first and last frames of the intended loop, along with the playback rate. Krita’s timeline documentation describes playback ranges and held frames; inspect the settings in the version you use. Keep an unchanged copy of the draft before changing the boundary. A selected group of frames in the editor is not necessarily the range a recipient will play, so include the intended limits in the handover note and later inspect the actual export.
Compare position, direction and pause
Watch several repetitions and note what changes at the return: an object jumps, a direction reverses suddenly or a pause becomes longer than intended. Inspect the neighbouring drawings instead of smoothing every part of the sequence at once. For a fictional blinking light or moving ribbon, test one boundary change and compare it with the original. The goal may be a deliberate snap rather than seamlessness, so relate the choice to the brief instead of assuming all loops must look continuous.
Inspect the delivered loop, not only the preview
Open the exported loop in its intended display arrangement and confirm the range and repeat behaviour. Check whether an extra ending frame or a different playback setting changes the pause. Keep the accepted file and the setting note together. If the motion is only a concept study, present it as that rather than evidence of a finished product or functioning physical device. A loop can be a useful visual reference without promising that an object has already been manufactured.
