blurry motion

[Lev]

i'm encoding/authoring a dvd which has a 29,97fps interlaced ntsc source using doitfast4u, reauthorist and docce4u..

i'm letting them figure out all the settings themselves resulting in this avs:

import("D:\APPIEZ\_DVDR_APPIEZ\DoItFast4U\new.avs\addaudio.avs")
LoadPlugin("D:\APPIEZ\_DVDR_APPIEZ\DoItFast4U\mpeg2dec3.dll")
Mpeg2Source("VTS__01_P01.16~9_1.d2v",idct=0)
LoadPlugin("D:\APPIEZ\_DVDR_APPIEZ\DoItFast4U\decomb.dll")
FieldDeinterlace()
AddAudio()

everything looks fine at first but i noticed that motion seems kinda blurry.. i was wondering if this is because of the 29.97fps source instad of the normal 23.97fps..

is this normal or should i use other settings for encoding?

hope you guy have the answers (:

Specifically, it's because of the FieldDeinterlace filter in the AVS script. For viewing on a PC, deinterlace is better then the alternative, but I watch almost exclusively on my TV, so my personal preference is to not deinterlace.

Be aware that if you do not deinterlace, you run the risk of messing up the field order, resulting in jerky playback. You should probably burn to an RW disk to make sure it's okay.

i agree with Kedirekin - if youre planning on viewing the dvd on a tv vice a computer then i would NOT deinterlace, you cant see the combing effect on a tv anyways and deinterlacing may create the ghosting effect that you mentioned. NTSC is easier then PAL - every interlaced NTSC DVD i encoded thus far has been upper field first.

thnx guys i changed my avs to this:

import("D:\APPIEZ\_DVDR_APPIEZ\DoItFast4U\new.avs\addaudio.avs")
LoadPlugin("D:\APPIEZ\_DVDR_APPIEZ\DoItFast4U\mpeg2dec3.dll")
Mpeg2Source("VTS__01_P01.16~9_1.d2v",idct=0)
AddAudio()

although i'm not sure what that idct=0 is but i just left it there..

and i encoded with only topfiels first checked.. burning it onto dvdrw at the moment (:

there's a bit of confusion with the topfield first option in CCE.
if your video is upper field first then you DONT check the top field first option, you only select it when the video bottom field first (i.e. DV video source, Most PAL interlaced sources) - it doesn't matter if its checked when encoding a progressive source.

you sure about that hendrix cause the guides say the opposite..

[influenza]

i think he's right. There's also an option in doitfast4u to invert the filenames if you use docce4u (and that's probably why)

[Tyris]

Last time I looked, the CCE FAQ in that forum agrees with what hendrix said.

if youre not sure what field your interlaced footage is then try both - trust your eyes..i have yet to run across a NTSC interlaced DVD that has been encoded lower field first. - like i said if your source footage is lower field first than have the upper field first checked...dont check it if your shit if already upper field first or you'll get a stuttering video and you'll be pulling your hairs out.

if by chance you get the fields mixed up you can run pulldown.exe and change the fields without having to encode all over again. :D
