Compare normal play with fast-forward modes
Choose an authorised file that plays normally and compare the picture at the available fast-forward speeds. Record the speed where motion changes from frequent frames to larger visual jumps. Keep this separate from buffering or missing frames during ordinary one-times playback.
Kodi’s documentation says its newer smooth fast-forward tries to show as many frames as possible, while earlier behaviour skipped between key frames. The newer method demands more resources as speed rises. A change between these modes is not by itself evidence that the original video contains fewer frames.
Inspect the version and nominated maximum
The current player settings include Maximum smooth fast-forward speed for Kodi version 22 and later. The documentation describes a configurable limit and says speeds above it use the key-frame method. Check the installed release and actual setting before comparing with another device’s demonstration.
Do not raise the limit solely to make a number match a tutorial. The publisher ties it to hardware capabilities and resource demand. Preserve the original value and make a deliberate comparison using the same file if a different limit is useful for the actual viewing task.
Report processing and source findings separately
If normal playback remains smooth but only high-speed search changes style, retain that distinction in the report. If normal playback also stalls, record the separate symptom and source characteristics. The fast-forward setting explains a particular navigation mode rather than every decoding or network problem.
For help, provide Kodi version, device, source file, normal-play result, fast-forward speeds and selected smooth-speed limit. Note whether the issue is expected key-frame jumps or a complete failure to continue. These details let a support report distinguish a deliberate processing threshold, limited hardware headroom and a source that cannot support the requested navigation.
