I mean here "stuttering" as a repetition of series (less than one second) of frames in a movie not depending on the movie player, not as stop-and-go, smoothless movement.

Although the first file from capturing has no frame drop (judged from the dialog box from the capturing program) and no stuttering, the second file from reencoding always has "stutterings". Any type of second encoding with any program results in the same. "Stuttering" occurs by several minutes, but irregularly. I don't think this is originating from in a specific scene because another second file has stutterings in different positions.

I also heard there might be stuttering in the second file if the bitrate in the first was too high. So I tried 1st-to-2nd reencoding with changing the bitrate and other factors as down below with every combination and with no success.

I originally aimed at making an Mpeg1 file for a VCD. Help with making a file with no stuttering in this direction (a good combination of factors in the first file) would also be appreciated.

Thank you.

Why do I reencode? Why not only editing: I want some visual effects in the movie.
