Better resolution of MPEG-1 w/ TMPGEnc

[Guest]

Archived from groups: rec.video.desktop (More info?)

I've successfully created a VCD from an AVI encoded with Xvid, by
taking the GSpot --> VirtualDub --> TMPGEnc --> Nero 5.5 route.
Everything works fine; it plays in my DVD player, as well as my
computer, but the resolution isn't as good as the original AVI. I
notice that my finished .mpg file takes up about 250MB. If I
wanted to fill up a CD-R (which is 800MB), how do I instruct
TMPGEnc to make a bigger file? I'm using the VideoCD(NTSC)
template, which an article at dvdrhelp tells me is what I need,
since my FPS is 23.980.

TIA,

Ian

if you avi is less than 35mins in length you can make a svcd

make sure you set motion search precision to highest quality(slow) in the
settings too!

VCD is always 352 x 240/288. If you want higher resolution, use the SVCD
template, which is 480 x 480. You probbaly won't be able to use the
resolution of your original AVI, as (S)VCD only supports standard
resolution.

If your VCD file is 250mb, it should end up around 450-500mb as SVCD. If
you go for a higher bitrate XSVCD, you might find that your player won't be
able to handle it, in fact it might not even handle SVCD. Only one way to
find out... 🙂

Thanks, Adam. I'll see if my DVD player can handle it.

I did not read the original message, so I may have missed something.
Anyway:

To begin with, I don't understand what do GSpot and VirtualDub mean in
the route. Usually, one would just encode with Tmpgenc. As Tmpgenc can
choke on XVid, an easy trick is to provide the clip under the guise of
an Avisynth script:

AviSource("The_XVid_Clip.avi")

As for the quality, I would rise the bitrate, even if it doesn't
conform to the Vcd standard. One cannot say beforehand what your
player shall admit, but usually one can try 1400 or 1450 kbps with
good results.

GSpot to determine what the frame-rate is, and any other details,
like what is was encoded with, what the aspect ratio is, etc.

VirtualDub to rip the audio track as a WAV file.

TMPGEnc to create an .mpg file using the .avi as a video source
and the .wav as an audio source.

I'll give it a try, although I'm not sure how to change that
setting. It seems as if everything is greyed out.

I see.

First load the regular VCD setting. Or you can try the "VideoCD
1246kbps (NTSC).mcf" template in the Template\Extra subfolder. This
one uses raises the video bitrate to 1249 kbps, and substracts from
the audio bitrate, keeping the sum of (video + audio) bitrate within
the standard.

Then, you can load "unlock.mcf" from the same "Extra" folder. This one
doesn't change the settings, but makes all of them available for
change.

Another way, is: Click the "Setting" button, go to the Video tab, and
click on "Stream type", "Size"... -do it, and you'll see what I mean.
I recommend yuou to follow this last trick, change the settings to
suit you, then lock them back and save a "MySettings.mcf" template.

More:

1) If your Avi had a better resolution than the Vcd, that would lead
to an obvious degradation in quality.

2) If the Avi was interlaced material, you may want to try getting it
in deinterlaced form before passing it on to Tmpgenc, and see if that
gives you a better result.

3) Vcd is low resolution and low bitrate, but it can still look very
good when the video is processed with denoise and smoothing filters.
You can try Tmpgenc's own denoise filter, or any of VirtualDub ones.
It may help give better quality to your Avi -> Vcd covnersion.
