pixelated??

[Hollywood312]

After burning my VCD, I tried it in my DVD player and it works fine. But........it's somewhat pixelated. It's tolerable I guess. What caused this to happen and how do I avoid it when burning part2?

Note: I was told that the size of the movie(mine was 352x288?) when converting it to MPEG 1/2 won't matter when you watch it on TV??

[nightwing7]

what was ur source, if what a bad source like old vhs, chances are thats why its really bad quality. What encoder did u use??

[Hollywood312]

I converted from .avi to MPEG 1 using TMPGEnc. The quality on my computer looked great. DVD quality. Crystal clear.

Although, like I said before, the .avi screen size was not that large to begin with. Would that make a difference?

It's almost like it's pixelated because it had to "stretch" to fit my screen size. What do you think? I didn't think that mattered when watching it on TV.

ya the AVi does look good, but when u convert u loose a lot of quality. The resolution of the AVI used must be low. I had a high quality AVI of x-men and i made it 2 VCD, it looks like VHS. But then i made a VCD out of a low rez AVi of True Lies, it looked very blocky. Generally AVi is bad for VCD conversion since its already so heavily compressed. DVD rip is the best way to ensure quality. So it varies.

I appreciate the help.

the quality of my avi was pretty good. And, when I converted it to VCD(or MPEG1) I played it back and it looked good also. only when I finally burned it and played through my Sony 32" TV. I don't know what the hell?

So I should stick to DVD RIP for the best quality?

One more thing.......does the screen size matter?
Example: If I have a DVD RIP that was converted to VCD with a screen size of 400x300, is it going to stretch to fit the TV size (like widows media, real player, etc. does if you scale it)or does that not matter?

Hollywood312,

The only size your tv (AFAIK) will play via your dvd player
is:

*** 352x240/352x480/480x480/704x480/720x480 ***

The above all play on my dvd/tv setup.

I think I read somewhere that you might be able to view
on tv with 640x480 encodes, but I doubt it - but it may
be true of very few dvd/tv players

[nightwing7]

ya DVD rip is the best way to go. For the stretch i usually get rid of that making the movie full screen, by cropping off the sides. Getting rid of the stretch is 2 much work for me. If u want to get the best results of DVD rip use SVCD instead of VCD, but make sure ur DVD player supports it.

hmm for the VCD on TV u might want to check ur sharpness on ur Sony TV, try lowering it. Otherwise i dont know what is wrong and why its so blocky. My guess its the highly compressed AVI that was used. Use DVD, its a nice clean source.

[Hollywood312]

Kool! That helps!

I still can't figure out why it's so pixelated?

Sorry for all the questions. I'm new at this. I just got turned on to this site last night and haven't left it alone.

[nightwing7]

is ur TV a wega, cause i hi rez TV's make VCD's look worse. Also what DVD player do u have, cause DVD player also decides the quality of video

[Hollywood312]

No. I'm not using a VEGA. All of my equipment is top notch SONY. I have a VERY high quality DVD player.

You say DVD Rip is the best way, but all the DVD Rips distributed now are of AVI format, and make a bad source for VCD/SVCD, unless you filter them. As you said, its because AVI is heavily decompressed. Anyway, the best source for VCD to use, is SVCD, or uncompressed or lossless AVI.

There is several reasons why you get pixallation.

First of all you need the basics of how VCD works and Mpeg1
DVD being Mpeg2 is available in interlace or progressive.
This means you have odd & even lines that make up the picture in the CRT for Interlace. Constant Lines for Progressive.

VCD Mpeg1 strips out one of the scan lines be it even or odd. Only using half the picture signal. So to explain this. If you where to take a slide picture of the same thing but just move one. Say a person waving their hand. You lay the slide ontop of each other. The background stays the same. But the hand is blurred. This is the pixellation (blockiness) you see. You have one scan still there as you are starting another and not leaving that scan.

So you said you have a AVI to VCD. This is the worse of the bunch. Think of Lines across the TV. AVI is only in the top 100's? Vhs is 275 / VCD and Broadcast is 330 / Laserdisc is 425 / DVD says 500 but is only 480I or 480P. The bigger the screen the more the lines are spread out. Thus larger monitors can show more flaws. This is why they have line doublers. Another problem you mention is you are doing Pal conversions. The screen is 288. Try NTSC which will drop that down to 240. This will also help because you will up the (FPS) Frames Per Sec. from 25 to 29.97 or just say 30 for video.

Best copys will come from DVD then laserdisc and last VHS. Anything less will just look like crap.

Last thing: Adjust your TV. Drop down the contrast, up the Brightness 3/4 and the sharpness 3/4 and see if this helps?


"O Yea" Best in encoder that reduces the most blockiness? Panasonic!
Hope some of this makes sense

[bravo]

this size of the tv does matter.i have a 50 and the movies i make look pretty good from avi,as good as vhs recorded from t.v.on a 30 they look noticebly better.the main thing i've noticed is get the max birate u can and encode on highest quality setting.if u want 2 test yr playback on a comp play it in full screen then u can get an idea of what it will look like on yr t.v.

[Douglesh]

My TV looks HEAPS better than fullscreen on my monitor, maybe cos my Mon. SUX

[bravo]

then if u get the best picture u can on your monitor imagine what the picture will look like on your t.v.then u can go the extra step and burn it.saves u time on burning a bad disc.

[Hollywood312]

First, I'd like to thank all of you for your help. I'm going to burn Part 2 of this film today and make a few adjustments. I'll definatley let you guys know how it came out.

Thanks again

Douglesh, what i meant to say u have to Rip a DVD to VCD to get the best quality possible for VCD, unless u have a better source, which is unlikely.
