BAD Pixellation on vcd movies!!!

[JordanLee]

Thanks to all those who helped me to understand the vcd world! It worked, i got it, and am even making dvd's with chapters menu's and personalised background music and pictures!!!! woohoo. BUT, nothing ever goes PERFECT for me, and there is another problem!

What i did:

Converted an .AVI file movie into a VCD compatible one (mpeg1), split it in half, and began writing the disc using nero burnin rom 5.5. It went well, but it pixellates!!!

Could this be due to the cd's? "master 700mb/80min 1x - 24x CD-R Pro's? Paid £5.95 for a pack of ten?

Or the write speed? I wrote the movie at 16x....... is that too fast?

Using other programs while burning? ive used other programs whilst burning other .DAt cd's and was unaffected...

I have tried to make the movie twice just to see wether it was just for the one time but it happened again

My dvd player: A Sony DVP- sumthin PICOT (portable) is vcd compliant, so it cant be that, besides i tried it on the dvd player downstairs and still pixellated.......help!!!!

[davemcg37]

i NEVER burn at any faster than 4x

[caish5]

Are you talking about MPEG artifact pixellation during fast action scenes or flat surfaces? Or are you talking about the picture completely breaking up into big coloured pixels from time to time?

[pretendbestfriend]

Hey i have had the same problem, that is the reason I am searching these forums for something I have done wrong.

I managed to convert the AVI to mpeg with tmpgenc and then burnt it at 8x with nero, but the picture when I play it on my dvd player is heavily pixelated all the way through and is almost unwatchable. Any tips would be much appreciated.

You shouldn't burn your VCD's over 4X as they pixellate and break up into small blocks when playing on your DVD player. It might also be due to crappy CD-R's.



Hope That Helps!!! :P

[pretendbestfriend]

Thanx for that, for some reason I cannot get my my burn speed below 8x but I shall try again tomorrow, cheers.

[musicman1212]

i burn my vcd's at 12x i dont notice any blocks. i'll try one at 4x and see what that looks like. does anyone else have opinions on vcd burn speeds and how they relate to picture quality? this is fscinating!

that's a load of crap!
I burn my (S)VCDs at 12x on cheap media, and never have any problems.

[JordanLee]

damn well i wont write at over 4x for movies again. I made this film for a mate andthe second disic broke up into large pixels every other second, then i posted this topic on here, re made it at 4x and it worked!!! thanks peeps!!!! VCD's are GREAT!!!!! the only draw back is putting them on two cd'........u have to change discs mid film.... ANDi make less profit

Hi JordanLee,
I sometimes have a pixel problem with video captures, not being a expert, but if you have a lot of detail (like water surface) or fast movement in your video, 1150 kB/s wont cut it. What I use is a higher bitrate like 1300 or 1500 kB/s. Granted it won't fit as much video on a disc, but the video quality is MUCH better. Now you will have a XVCD.
Hope this helps.

[JordanLee]

Thanks......but hwo the hell do i change the bitrate?

[Anonymous65]

To make a compliant VCD, you don't change the bit rate.

How high speed you can burn a VCD depends on your CD-R burner, the CD-R media and the DVD player. With a good burner and good quality media, I'm burning VCD's at 12x as a standard. Some people can burn a VCD at 48x. Generally, the faster you burn the media, the greater the deviations are on the CD-R disk. Most all DVD players will play the VCD at 1x speed, not 48x like a CD-ROM (that is designed to handle the high speed reading).

[MpegEncoder]

The myths about burn speed are sooooo numerous. But thery're just not true. I burn all my CDs including VCDs at 32x and they all work fine (with any media). The drive and disk makers know what they are doing.

The typical problem of "pixellation" when burning with Nero is that people are letting Nero reencode the file with Nero's built-in mpeg-1 encoder (which is NOT very good). This is also why they often complain about lengthly burn times.

Your best bet is to use VCDEasy to author the disk. Then you can use Nero to burn the bin/cue image.

Hope that helps.

[mats.hogberg]

Hear Hear!
Nero is somewhat unclear on its intentions, so most miss the fact that Nero is reencoding the MPEG once again, resulting in below par quality, part caused by Neros crappy encoder, part caused by the inevitable quality drop when reencoding. Why use Nero for authoring VCDs, when VCDEasy is around?

I burn mine a lot faster than 12x and have NEVER had a problem, except for crappy rips to begin with.

[vitualis]

S/VCD burn speed does not affect video quality per se.

As long as your CD burner and media can handle the speed, the bits that are written on the CD are identical. There is no "loss of data integrity" that will cause any difference in the video quality.

It is generally a reader problem. Many DVD drives do not read CD-R discs very well (especially those that were not designed for it). For these drives, they can have a more difficult time reading the disc if it has been burnt at a higher burn speed.

If you have a DVD drive that is designed to read CD-R discs (and it does so well), it usually makes no difference what burn speed your burn at.

Well im gettin truly pissed off now! im wastin all of my cd's just to get a good cd. I just tried writing a vcd at 2x speed and it pixellated more than ever...... Im tryin to create the vcd with menu's and intro movies with ulead's dvd movie maker......is it that? or could it be the background music? the program crashed a couple of times when trying to listen to the mp3 files? i need the intro movie and the menu's on my dvd's so what else can i use?

[vitualis]

I sounds like your player doesn't like reading your CDs. It is unlikely to be an authoring problem.

Burn an audio CD on the same media. Does it play that okay all the way to the end?

As for other authoring programs, VCDEasy is highly recommended. However, your problem is again, probably not due to authoring.

And try a different brand !

[davemcg37]

i generally burn at no more than 4x because i do get pixellation probs on my toshiba sd210e, however i've found the brand of cdrs makes a difference. i tried to watch a copy of dragonfly today that i'd just burned and i had horrendous pixellation probs. i then thought i'd try a cdrw and it worked just fine

[THA]

Well, are you absouletely sure that you used MPEG-1 VCD format and not SVCD format? If it is MPEG-1 VCD format, then it's probably a bitrate problem. The only problems I have at writing at fast speeds is the DVD player not picking up the disk. You might also want to try the header trick in case your DVD dosn't like or is limited to certain formats. I usually get really bad pixellation and sync problems when I play mainly SVCD's since my DVD player dosn't support it, officially.

My bad!!!

My dvd player is a Sony Picot - dvp-pq1 dvd player and works with vcd svcd and everythin else, so it aint that, and also the disc does exactly the same thing on another dvd player downstairs! i can only put it down to 2 things, either the AUTHORING or the MEDIA because:

when i play the movie after converting it to vcd compatible file, i play it and it works fine, (in windows media on the pc)

when i test the cd before writin in uleads dvd moviemaker it works fine....

but when i play it in the two dvd players (meaning its not the player that is the problem) it pixellates beyond belief! so its either the authoring or the media, and im about to test a cd RW disc of the same movie to find out

im a man on a mission lol
