I have Bar Lines on my finished video please help

[Ghettorapboy7]

I encoded a couple of movies in the past and they had these like bar lines in them so I just used macrovision methold to copy them, but does anyone know how to get rid of these bar lines?

Are the lines vertical or horizontal ? Is your source video mpeg or avi ? CAn you post a screenshot ?

Even more info is needed: source, settings, programs used, encode to what (mpeg1/mpeg2; VCD, SVCD, DVD), etc. etc.

My first thought it it's interlacing. If you encoded to a MPEG2 source then it's ok, if MPEG1 then not. But need more info.

sry for the lack of info here it goes:
1. The lines are horizontal
2. My source is a .vob file from a ripped movie but I was converting it to a .mpeg file to be burned as a VCD
3. I don't kno how to post a screen shot sry
4. I used TMPEG Plus 2.58.44.152
5. I didn't chage any of the settings that I can remember and I was encoding it to a VCD in .mpeg1 file format

thanx for the help u guyes

Ok, that sounds like interlacing. Do a forum search on interlace/interlacing, telecide/IVTC and/or pulldown for more info. But here's an outline. Your TV is setup to display 29.97fps interlaced video. Each frame is actually made of two fields. One field contains all of the even lines, and the other field all of the odd lines. These fields are called either top/bottom or odd/even.

So you TV is really setup to display 60 fields/s.

You computer can display any framerate at any resoltution of progressive video. Progressive field (eg. films) each frame is a complete picture, and they are displayed one after the other (think of a film strip).

Interlaced video will never look right when played on your PC. You'll be able to see the seperate odd/even lines as each field is shown (aside if you play with a software DVD player it'll de-interlace on the fly).

MPEG2 video can display an interlaced source (or progressive). So even thou you might see interlaced 'artifacts' on your PC, they will NOT be visable when you play your SVCD/CVD/DVD on your TV.

MPEG1 video can ONLY be progressive. That means if you put an interlaced source on a VCD, the interlace 'artifacts' lines will still be visable, normally during high motion scences.

So you need to deterlace the video. There are a lot of ways to do this. The easiest way is to resize from the DVD source 720x480 to the VCD standard 352x480 but only encode one field. Each field has a resolution of 720x240, and wtih only one field, no interlacing artifacts are introduced (I do this with avisynth)

TMPGenc can also deinterlaced. Click on settings, then the advance tab.

With all that said there's most likely an easier way to do this. Remember that I said that TVs can only display 29.97fps interlaced video. And that most films are shot progressive and at 23.976fps.

To conver the 23.97fps progressive source, into a 29.97fps interlaced video you run a process known as teleciding (aka 2:3 pulldown). Well you can convert that interlaced video back to it's original progressive source by a process known as inverse teleciding (aka IVTC).

Two options.

1) open the VOB files in DVD2AVI. Open the stats window, then hit the preview button. Look at the main movie (not the opening, trailiers, etc). If the stats windows says the movie is film (or 80% or higher film). Then you can select 'force film', in DVD2AVI which will 'output a progressive stream' d2v file (I'm skipping a lot here, read the guides for more). OR

2) Run a true IVTC process either in TMPGenc (again under advance settings) or with AVISynth/VDub.

That's a long post I know. But the whole process is actually pretty simple when you do it. Here's an outline (PLEASE READ SEFY'S GUIDES FOR MORE DETAIL AND PICTURES).

1. Rip DVD to HD
2. Load VOB files in DVD2AVI
3. Preview DVD, determine it NTSC or film. If film enable 'force film'
4. Generate d2v and wav file
5. Load D2V and wav file in TMPGenc, load favorite template, encode

In your case you would use either the NTSC_VCD or NTSC_VCD_FILM template. Luck...

thanx alot man ill try this then give ya a holler

[Ghettorapboy7]

I have one more question where is the force film opition in DVD2AVI?

[Sefy]

It's under the "Video" menu, in the "Field Operation" submenu you will find the "Force Film" option

thanx man
