Why Does Ray3 Modify Show a Five-Second End Card?

Identify the Mode and Valid Input Interval

The cited guide is specifically Ray3 Modify: User Guide, published December 12, 2025. Its combined Input Video + Keyframes + Character Reference instructions begin in Modify mode with an input video of at most ten seconds and a character reference image. Do not extend its rule to an arbitrary long upload, every Keyframes mode or a later Ray model.

Its End Frame note applies when that input is longer than five seconds. Thus the relevant documented longer-input interval is greater than five and at most ten seconds, subject to the workflow’s other requirements. The displayed end card represents 0:05; this note does not mean that the source or transformation stops there.

Check the combined-input steps and End Frame note together in the dated Ray3 Modify user guide.

Compare the Card With the Required Action

In the documented sequence, click a keyframe card to open the Modify frame editor, check use character, submit the keyframe instructions, then adjust Modify strength and submit the video. Identifying those objects matters: a frame-editing card and the video’s actual endpoint are different controls and observations.

Illustrative eight-second source, not an executed Luma upload: an open box is visible at 0:05 and closes at the true eight-second ending. The note explains why its end card can show the open box. It does not establish whether a chosen instruction can control the later closing action exactly.

For a four-second source, this particular longer-than-five-second note does not determine the card’s behavior. Verify the selected mode rather than inventing a five-second sample beyond the source. For an input longer than ten seconds, first resolve the cited workflow’s input eligibility; do not apply its sampling note as though the upload were valid.

Record the Actual Timeline Before Revising

Use the blank record for the actual mode, video identity, duration, content at 0:05 when present, true endpoint and desired control moment. A filename change or a new verbal description does not change the documented sample timestamp.

If the required action occurs outside the moment addressed by the card, examine available workflow choices or source preparation and verify their own constraints. These are decisions to investigate, not guaranteed workarounds or claimed generated results.

Review the Whole Result If Generation Is Performed

Keep the actual generation identifier and inspect the full sequence, including the desired closing action and true ending. A plausible card alone is not evidence that the requested action or product consistency succeeded. Record unresolved control or quality rather than pre-filling an approval.

No upload, modification or generated-video test was performed for this guide. The method explains the cited control-frame rule and an observation plan; it does not promise exact endpoint reconstruction.

Use the product-video duration guide for the delivery brief; keep that creative duration decision separate from this dated mode’s input limit.
