1800k For SVCD?

[Drenzio]

I backed up my Gladiator DVD to SVCD at 1800k CBR and sound 224.
Disc 2&3 came out great! Even during the motion scences, but disc 1 looks
like its flickers on the motion scenes even during the slightest motion and its freaks my eyes out. What happen? 2&3 have motion scences and they look fine. Is 1800 CBR enough? Did I maybe set something wrong on disc 1? This is my first SVCD.

Thank you for any help.

I am using TMPG...At 1800k CBR
Can someone give me some ideas?

Thank you.

Sounds like you have turned down "Motion Search Precision" set this to high quality (slow) and try this on an action scene to see if it looks better.

[Drenzio]

Hey thanks for the response, but I did try that thinking that was the problem and it did the same thing. I don't know enough about doing this to even guess what to try next.

1800 is really to low for SVCD using CBR. Try it again but use VBR.
Average=1800, maximum=2500,minimum=300
Are you using standard 480x480 resolution?
VBR will take twice as long as CBR but will handle high motion better than CBR.

In addition to what wulf109 suggested, try using 352x480. Unless your DVD player is old it should play fine. Results should be even better without losing and noticeable resolution.

[Drenzio]

Yes I am using 480x480 standard and I will try VBR, but why do you think that disc 2& 3 came out good they have lots of action also. The quality is there on disc 1 but the motion is not smooth, it kinda flickers or steps instead of gliding through the scences.
I don't know if that is the correct wording fot it. If that makes any sense.
Thank you for all the help

Ok I figured out what was wrong.
I had NTSC Film set up without the Inverse Telecine checked, as soon as I
checked this option it worked ...no more flickering or jerky motion.
I have made 2 more movies since and they look good even at 1800K
So what the heck is Inverse Telecine?

Thanks for all the Help

Inverse Telecine is a process where video editing tools reverse telecine process. Basically inverse telecine (or IVTC as it is also called) brings back movie's original framerate from NTSC's 29.97fps to 24fps.

If you follow the guides on this site you will learn a much better way to do this. IVTC takes forever and there is a chance that it won't work correctly, especially with TMPGenc's IVTC filter. If you instead process your video through dvd2avi first (you should be doing this anyway) and use the forced film option it will output your video at 23.976fps. From there encode at 23.976fps and add the 3:2 pulldown flag (or just use the NTSCfilm template) and you will have a perfect SVCD.

See, NTSC DVDs are stored at 23.976fps and have a flag in them which instructs the decoder to telecine them to 29.97fps on the fly. What you did is you took that 23.976fps source, let the decoder telecine it to 29.97fps, and then ran a filter to TRY to reverse the process back to 23.976fps again. If you just use dvd2avi's forced film instead, it just skips the telecine process to begin with and lets you access the progressive 23.976fps source.

Ok...thanks for all the info I will give it a try and I will let you know how it goes.


Thanks again
