Cant i never burn a VCD with a decent quality?

I using pctv pro... at 1st i try to capture using their tv vision with the standard vcd foramt & i try to burn using nero express... After burning finish. I watch it on my vcd player i found out there is a lag frame, crack sound , & lousy graphic ( got square)

Cant i never burn a VCD with a decent quality like vcr gaphic also not bad ...

I dont feeel troblesome for covert or wht...

the most is i burn into vcd can get vcr gaphic (vcr gaphic which is direct rec from tv itself) also gd of cos the clear will be better.....

I had try to burn into svcd but my vcd player dont support that & i dont have dvd so i only can watch it on vcd..

i hope there is a helpful pppl can help me by teaching me...

i be looking for help quite a long time & waste quite a few cd for test..

pls teach me ...

*beg everyone* =(

I'm not sure if I understand the question fully.

But, it sounds like the problem may be your method of capturing.

Depending on the software you use, and the power of your PC, capturing in realtime to MPEG-1 might be what's causing the bad quality.

You might want to try capturing to a less compressed format first.

This takes up more disk space, but the computer can do a better job, as it doesn't have to do so much number-crunching to do the compression in realtime.

Maybe try capturing to huffyuv, or one of the M-JPEG codecs? VirtualDub works well with huffy, and there are guides on this site under 'How To... Capture'.

Then, you can encode later (e.g. with TMPGEnc) and the PC will have more time to do a good job of the MPEG-1/VCD encoding.

Nero should work fine to burn/author the VCD with the output from TMPGEnc.

' hope that helps,

you mean i need to rec into Uncompressed AVI file thn covert to mpg ?

Uncompressed AVI take quite alot of space.. yesterday i try to use it just few min it use up more thn 500mb

[theDruid]

no, i don't mean uncompressed - i mean you should use less compression when capturing.

MPEG-1(VCD) compresses the original by around 25:1 (source)

Huffman compresses the source by around 2:1

So, yes you will need a lot of disc space compared to realtime MPEG-1 capture, but the quality issues you described make it sound like your PC needs more time to do a good job of the MPEG-1 encoding.

Use HuffyUV or one of the M-JPEG codecs in the tools section on this site and see how you get on.

At the end of the day, you cannot expect to get good results trying to make a (relatively) slow computer with limited disc space capture in realtime to heavily compressed formats. In the words of Scotty, they dunnae hae the puwer.

If you really want to get excellent results you're going to have to do one or more of:

* capture to a lower compression format, and re-encode later (to do which you may have to invest in more disc space)
* upgrade your PC/setup so that it can cope with realtime capture to high-compression formats.

Sorry - I wish I could give you better news!

cheers,

IF you are use to DVD and formats like that, you will never perceive VCd as good quality. The specs for NTSC VCD is 352x240 44.1 mhz 1150bit rate. You may be under the impression that VCD ='s VHS. It doesn't. There are numerous threads that talk about this. Also, there will probably be at least one reply to this that says they get good VCD quality....but anyway.

If you want to get the best quality that you can out of VCD with your current setup. You need to cap using an application like vdub, IUVCR, etc. (Everyone's going to blast the next comment) Capture at the highest bitrate and resolution you can. I dont know about your cap card, but I have the ATI-TV tuner and here is what I do:

1. Cap TV or VCR with IUVCR using picvideo codec (you may want to go huffev or uncompressed, your choice) set at the the notch below highest quality (19) 720x480
2. Use CCE (actually I use it through DVD2SVCD) or TMPGENC to convert down to final resolution (I output to DVD, so I don't convert down, but use 8000bit CBR).

Make test clips because every scene (it feels like) will require additional tweeking.
3. Burn with MF2 - author the DVD

I dont want to make an absolute statement since I have no idea what your cap software is like, but from what I have read, in general, the bundled software capping with a card is not the greatest. Take it for what it is worth.

Is there a special reason why you want VCD? If your DVD player can handle it, try to go CVD (352X480 2600'ish BR)

[theDruid]

macleod,

your points about capturing resolution (i.e. go for the highest you can), and the poor quality of bundled capture software are spot on.

However,

I had try to burn into svcd but my vcd player dont support that & i dont have dvd so i only can watch it on vcd..

so it doesn't sound like he can go for anything other than VCD.

cheers,
mcdruid.

[edit]sorry - didn't see that you'd said CVD - he maybe should give that a go [/edit]

I had try to rec use virtual VCR programe to capture my tv show & use tmpgenc to convert into mpg & burn it into vcd.. it look better than last time but isit becos is vcd.. i can still see abit light type of square gaphic (i dont know how it call)

isit becos is vcd or we do covert before so the gaphic cant compair with the realtime tv - vcr gaphic? on tv

If i capture using dvd format & covert into vcd ... will there be any diff if i use vcd format & convert into vcd? (will the gaphic diff? good or bad for which one)?

ya u r right .. i only can go for vcd.. dvd too ex in my country..

[macleod]

although others may disagree, you best best is to cap as HIGH as you can and then when you do your conversion, convert down. ex. cap at 640x480 (talking NTSC here) and then do the conversion to 352x249 1150 bit rate and 44.1 audio. You will also want to use noise filters, which is an art rather than a science.

If you want to get the best picture you can from a TV cap, I would cap it the highest that you can without losing frames and then convert down.

capture with showshifter (free 30 day trial) as high quality wmv2 (2 hours = 1.5 gigabytes)at 352 x240 file will save as .wmv, change .wmv to .asf and encode in tmpgenc standard vcd template. burn with nero. Perfect quality every time
