cce encode has jerky motion

[maxwell3]

Finaly got cce 2.66 to work did an encode to mpeg 2 from an avi capture of vhs . Came out great except for some jerkyness on motion . Can someone whos familiar with cce give a little advise . I used no filters and changed no settings from where they were at default it was a 3 pass encode vbr 6000.

Not sure, but sounds to me you have something wrong with the framerate, either in your capture or the CCE settings.

what filters do you have running through it?

[maxwell3]

I used no filters at all . I also ran the same avi through Tmpg DVD source , downsized to 352x480 vbr 8000 multipass vbr and the resulting mpeg 2 is just as good as the CCE encode maybe alittle better and has no motion problems at all . Isnt there a setting of some type in CCE that would affect motion . When I say its jerky motion its not really severe . The movie is still watchable . Its just not as good as the original source or the Tmpg encode .I ran both encodes through tmpg dvd author and burned dvd's then compared them to each other and to the source vhs
So anyway that eliminates the source framerate I dont know why the frame rate in CCE would be different from tmpg but Ill check. Thanks

You're right, the source must therefore be fine

have you tried zigzag instead of alternate???

[maxwell3]

Im willing to try rhat I already erased the source avi my harddrive,foolish on my part , or I could try a reecode on the same source . thanks for your suggestion

Changing between zigzag and alternate shouldn't make a difference with jerkiness.

Jerkiness is usually field-order related. If the source is interlaced then this would make sense (change offset line from 1, the default, to 0). I have no idea whether the source avi could or would be interlaced though - never done capturing.

[sh03z]

No actually it does make a difference.

If you have a interlaced video and you deinterlace, you would then use the zigzag pattern.

I'm 90% positive this source IS interlaced (VHS).

@The Slapper

If the source is interlaced then this would make sense (change offset line from 1, the default, to 0).


Then this might work.

[Matthew]

Ummm, I stand by my point that it shouldn't make a difference in terms of jerkiness.

I know very well that zigzag is traditionally better for progressive material, but that doesn't mean that it affects jerkiness.

The capture is from a vhs source which is from tv ( interlaced ) and I did not deinterlace . I did notice upper filed first was checked in option maybe that the problem Thanks to everyone at least I have some things to try .

@Matthew:

Seems you are right, I just re-encoded the movie I based that decision on, and it happened to be my field order that was wrong.

Enabling the the appallingly named "upper field first" is the same as offset line =1 (for later versions). For interlaced top field first material (as it sounds like yours is), then checking this option will output material that is flagged as top field first but been changed to bottom field first by CCE. The setting is designed only to turn interlaced bff material into tff material.

More detail about this issue is in the CCE FAQ I think :)

if youre encodes are jerky then you got the field order wrong...instead of reencoding the whole thing over again...just use restream to fix the field order
