Video becomes laggy.

Post by Legendarion »

After an encode of a movie the video becomes laggy the first minutes and seems to correct itself around 3 minutes and 50 seconds.
Is there some sort of a fix for that/any preset to prevent that?

Details: DVD (ISO file), NTSC.

What do you mean by "laggy"?

Is the audio out of sync with the video?

Is the video framerate low?

Most of it is technically fine. But the best word I can come up with is that the picture somewhat stutters.

If I watch directly from the ISO file the picture goes smooth. Like when people walk and the camera tilts or pans smoothly. But if I look at the encoded file from the same spot, it stutters.

Same as source constant framerate does not account for frames that may be doubled by deinterlace.

Code: Select all

[20:23:58] + Comb Detect (mode=3:spatial-metric=2:motion-thresh=1:spatial-thresh=1:filter-mode=2:block-thresh=40:block-width=16:block-height=16)
[20:23:58] + Decomb (mode=39)
[20:23:58] + Framerate Shaper (mode=1)
[20:23:58] + frame rate: 23.976 fps -> constant 23.976 fps
That combination will cause some "stutter" whenever there's interlacing in parts of the video.

Code: Select all

[20:33:12] comb detect: heavy 5108 | light 2377 | uncombed 136741 | total 144226
[20:33:12] decomb: deinterlaced 5108 | blended 2377 | unfiltered 136741 | total 144226
[20:33:12] vfr: 141541 frames output, 2685 dropped and 0 duped for CFR/PFR <-- dropped frames to maintain target frame rate
Depending on the playback environment, you want to use same as source with variable framerate instead, or manually forcing a higher frame rate of e.g. 59.94 fps to ensure no frames get dropped.

I re-encoded it with "Variable Framerate" and it now goes smooth. Thanks, man.
