horizontal lines on the screen when encoded as SVCD???

[hyena77]

i encoded a video for the first time as SVCD last nite, burned it to a CDRW to check it out and even though the overall picture is clearer vs VCD, there's also some lines running across the screen distorting the images. these are the settings in TMPGENC Plus (ver2.521) i've set for SVCD:

General tab:

MPEG-2 Video
Size: 480x480
Aspect ratio: 4:3 Display
Frame rate: 29.97 fps

2-pass VBR (VBR)
Avg bitrate: 1831
Max: 2592
Min 1100

Profile & Level: Main Profile & Main Level (MP@ML)
Video: NTSC
Encode: Interlace
YUV: 4:2:0
DC component precision: 10 bits

Motion search precision: High quality (slow)

Advanced tab:

Video: Interlace
Field order: Bottom field first (field B)
Source aspect ratio: 4:3 525 line (NTSC, 704x480)
Video arrange method: Full screen (keep aspect ratio)

System tab:

MPEG-2 Super VideoCD (VBR)

is there anything here that may be set wrong? i've gone with these settings based on my readings in the forum. i'm also wondering if it could've been caused by me using my PC to do other things while it was encoding. unlike a previous version of TMPGENC i used, this one doesn't completely slow down your system and besides not being able to use your CD drives, you can pretty do anything else like surf, email, d/l, etc. so maybe TMPGENC needs to have 100% cpu resources to encode the video perfectly??

Just a guess...

Are you are viewing it on your PC using Windows Media Player? If so, what you are seeing is INTERLACING or COMB EFFECT. (Read about 1/2 way down your log and you'll see it is an interlaced file).

VCD does not support interlacing, as it is a progressive scan format only. Therefore you would not see interlacing effects on your computer when playing back the VCD version of the file. However, SVCD can be either interlaced or non-interlaced (progressive).

If the intent is to view on TV, then interlacing is GOOD, as TV's are an interlaced scan device. If the intent is to view on your computer, you will need to de-interlace, or use a computer-based video player the auto de-interlaces, such as Power DVD (WMP does not de-interlace).
