Does Burning Speed influence on VCD - SVCD quality ??

[fokablam]

I burned a VCD from a DIVX, it became with worser quality than the divx on my DVD player, I burned it on 4x, I wanna know if speed influences on quality?? And wich Burning prog improves better VCD - SVCD recording quality (or they are all the same??) I use NERO 5

Burning speed doesn't affect quality, only encoding speed affects quality. The faster the encode, usually the lower quality the result is. However burn speed doesn't affect quality because the quality has been detemined before. The same files will be burned at 4x as would be at 12x.

Theoretically a CD is burned with digital data and will contain exactly the same data regardless of it was burnt at 1x or 24x. I certainly have never had any problems with CDs burnt at a high speed.

On the other hand I suspect that a CD burnt at 24x will be more prone to the occasional burner "glitch" and may not prove as reliable as one burnt at a slower speed but the jurys out on that.

To answer your question, the burn speed had nothing to do with why your movie looks crap. DivX video is a remarkably bad source format for re-encoding. Provided you used a decent MPEG encoder (such as TMPGEnc) and gave the video enough bitrate then there is not much else you can do.

Burnig speed won't effect quality BUT to my experience it will effect compatibility.
Brand X cd-r when burnt Y speed will not play in stand alone player,but when burnt z speed (usually lower speed) will played OK. But brand M cd-r will play OK at a X burn speed

That's a lot of variables, but under that code what mike416 said was true. I burn vcd's at 12x, but many guides will tell you not to go beyond 4x due to problems with players reading them.

I burn at 24x and hav'nt had a problem with my pioneer 636 playing them yet.

Thanks a lot
I use TMPGenc for encoding MPGs for VCDs, and M2V for SVCD...
To produce MPGs with FULL QUALITY, must I put the Rate Control Mode on CONSTANT QUALITY ???? Doesnt matter how big MPG will be, just quality matters to me...

[Dave B]

I don't know what you mean by "Full Quality" but I guess you mean that you don't want the MPEG to be noticably worse than your source video.

If that is the case then I would recommend re-encoding to either a high bitrate SVCD or DVD. CQ is an algorithm used to produce an MPEG file, it does not necessarily have to be used to create a high quality file.

If your aim is to play the video on your standalone player then you should experiment to find the highest bitrate it will support.

here is the way i see it

i bought a 40x cd burner, i'm going to burn at 40x
i bought cheap media, my discs are going to **** up and not play in some players
i learn not to buy cheap media, i buy decent and good media and burn at 40x
my burned discs play in my dvd player just fine, but they dont play in my friends dvd player from 1997..
**** him, he needs to buy a new dvd player anyhow.. they're cheap nowadays, its not like he has an emotional attatchment to his first dvd player.

see thats how it should be.

**** burning at 1x, 2x, 4x or whatever.. if you're so goddamn cheap that you still have a slow cd burner that is prone to making bad discs at its "high 6x writing speed", then you deserve to get fucked, and if you've got an old player **** you.

go spend $200 and get yourself a 24x cd burner and an apex dvd player. all your problems will be solved. just buy decent cd-r media.. atleast memorex 50 pack spindles for $20. shit, we wouldnt have to have this discussion 893408208902849723974 to the gazillionth power if you fucks would stop being so goddamn cheap. shit.


okay i'm done.

[jeex]

oh by the way. burning speed does not affect quality, aslong as you're not a cheap ******* *******

[House de Kris]

Yowzer Jeex, forgot your meds this morning? Your help Jeex, though well thought out and concisely stated, may not apply too well to the question at hand. It would appear that Fokablam IS indeed a cheap ****. He stated at the get go that he downloaded a DIVX file and burned to CD. That right there should indicate how cheap he really is. Why not just tell him to buy the damn movie? Stop cheaping out with DIVX shit, as it were.
