why quality loss from pc monitor to tv?

[jayz2002]

Hi!
i'm encoding avi to mpeg1 using tmpgenc with kwags kvcd plus template, when i preview what the outcome will look like on the pc monitor it looks great but then when i burn it to a cd it looks pretty bad on my tv. i was wondering why this is? the resolution of the mpeg is 704 x 576 and my tv is pal/widescreen if this helps. thanx in advance
i was thinking the preview would show you what it would be like on the tv screen.

[Baldrick]

THe tmpgenc preview?? it only showes the source material not the actual converted.

Or do you mean after you converted it?

[jayz2002]

sorry, i meant after coversion! does that help?

[KingJohn]

704 x 576 ? your making a non standard VCD then ?

Video-CD PAL (MPEG-1 352x288 25fps CBR 1150kbps, Layer-2 44100Hz 224kbps)

Video-CD NTSC (MPEG-1 352x240 29.97fps CBR 1150kbps, Layer-2 44100Hz 224kbps)

Does your player play non standard VCD's ?

kwags templates look, in my opinion, terrible on a good TV screen. No matter how you change the gop, there is a bitrate v's resolution threshold that
kicks in at below 6,000kbps @ higher than CVD frame sizes. You might want to try CVD at 352x576 or SVCD @ 720x576.

Not on my HTDV
Better download the latest PLUS samples and check again.

@jayz2002:
You're probably encoding AVI ( DivX ), and that's why your output is blocky. I don't recommend re-encoding ANY DivX to mpeg.

Is that meant to be a joke, considering most people here are converting DivX to mpeg. Nothing wrong with DivX, lots of high quality movies available using many types of different codec's

[Olli]

Exactly ...I only convert high quality DivX DVD rips to XVCD.
The quality I have achieved is pretty good considering my DVD player does not do SVCD or high bit rates....

No. It's not a joke. Nothing is wrong with DivX, and nothing is wrong with an MPEG. Unless you try to convert either of them again to something else. Like a DivX to MPEG. Do you know the meaning of "Another generation of encoding"?

I am having same problem, compiled avi using premier6, but when I encode to mpg, it looks terrible. What am I doing wrong. I'm trying to make a vcd, but the quality of the mpg is not worth it....thanks

tmichaelh, are you using the CCE plugin or at least frameserving
to Tmpgenc ? If not, you are going to get a visit from the crap

I think the guides (left hand side) have info on this.

I use KVCD plus (352X240) to encode DVD-rips and they look great on my TV set, played by Apex AD1200 DVD palyer (a great one!).

Kwag, will this template produce the same result if I use it to encode an AVI file I capture myself from live broadcast? I tried a short piece, and it does not look as good. It may not be your template's problem, because the source (live tv broadcast) is not as good as DVD-rips.

[jayz2002]

thanx guys! i'll try and do a cvd and see what happens then! i have a cyberhome adl 528 that'l play almost anything.

[SatStorm]

Cyberhome 528 ain't good.... It doesn't play SxVCD for example!
Older models are much better. Mine is M212 and it rocks! Excange if you can!

Nothing wrong in converting a DivX to mpeg either, with a good source the result will also be good, no mater if it is encoded a second time. There are plenty of VCD's that are as good as DVD's, they all originated from DivX downloads.

So then it means that "Another generation of encoding" doesn't mean anything to you?
So you say DVD->DivX->(xyz)VCD is the same quality as DVD->(xyz)VCD, if the DivX is a very good quality?
You're wrong my friend. You're adding "one more" layer of macro blocks on top of the original, with the second mode. Try your DVD->DivX->(xyz)VCD on a HDTV, and you'll see what I mean.

I dont think anyone is talking absolutes here Kwag.
If the source file is good quality e.g. a DivX DVD rip you can still produce great looking VCD's.

Of course going direct from DVD - VCD will produce cleaner results but is not always an option people have available to them.

[SatStorm]

If you use DIVX @ High bitrates, we talking about 2500kb/s or more, then DiVX is like using PicVideo mjpeg codec @ ~19 value. Unfortunatelly, grabbing to DIVX realtime insteed of PIC video or Huffyuv,needs powerfull CPUs with Virtualdub. My 1700XP can do it with no frame drops for 352 X 576 resolution for example, using a couple of realtime filters (which is possible with picvideo of huffyuv).

From the other hand, TMPGenc handles DiVX better than PicVideo, so yes, it is a good alternative if you can use DiVX for capturing the first place, @ 2500 and higher bitrates.
XviD is even better, 'cause supports interlace, which is the most important thing in analogue grabbing (we don't talking for DVD ripping here). Same limitations with DiVX also for CPU power here...

Now, for downloaded movies with bitrates like 600-1000kb/s @ Any resolution, for me the best way is like VHS: A xSVCD with VCD bitrates/resolution, interlace output (whatever that means for this resolution), and VBR. The use of couple of filters is neccessary. That way, you may have change for equal results with the divx source. Do some tests with Sefy's SxVCD to see it yourself (if you are lucky and your player support that format)
This is my opinion, other users may have different conclusions

Another generation of encoding means nothing at all, Who cares if the quality has dropped, its not dropped to such a level that its no longer good quality. DVD > DivX > VCD,XVCD,SVCD will always produce excellent results. Even DivX CAM's are good when converted to VCD, so maybe its time you got a better HDTV if yours is showing up artifacts and micro blocks.
