Cause: Improper target interlacing field order
For interlaced output, the target field order may be incorrect for the playback device.
Check the requirements of the intended playback device to determine the proper
interlacing setting.
Video movement appears jumpy
> Result > Original image
Movement in the video does not appear smooth – it seems to jump instead of move in a
fluid fashion. Objects in motion seem to jump or “flash” to the next position like a strobe
effect.
Cause: Video frame rate too low
If the video frame rate is too low, motion in the video will not appear smooth.
Increasing the frame rate will help to improve the fluidity of motion but will also
make the file size larger. Generally speaking, a frame rate below 15fps will result in
unsatisfactory playback.
Cause: Streaming connection speed too slow
Users viewing a streaming file that was made for a faster connection speed may
see this type of “snapshots in time” effect. The user need a faster connection to the
streaming server, a progressive download file should be used instead.
Cause: Playback machine too slow
Some formats play with different frame rates depending on the speed of the viewer’s
machine. Try playback on a faster computer to see if it plays better.
