I really like the MainConcept MPEGEncoder much more than TMPGEnc,... is there a way we can convert a KVCD template to MPEGEcnoder tempate? It does support templates ...

Hi HansLuyten,

I believe you can use the KVCD parameters with MainConcept. Just take the KVCD GOP settings 1-24-2-1-24 and the KVCD quantization matrix, and put them in MainConcept.
Let me know how it works, because we already benchmarked that encoder against TMPEG, and we agree that it is faster than TMPEG, but quality wise it's still not there

Hi Kwag,

I did take a look at it and I'm afraid it's a bit too confusing for me ...
In the quantize area it says intra and non-intra ... that's where they lost me

I also did set the bitrates;

constBitrate=1000000
maxBitrate=2400000
avgBitrate=1000000
minBitrate=300000

The GOP,I/B/P frames however remains a mistery to me ...
Without changing these and only quantize and bitrates, the encoders reports an error

by the way: for those that are interested, MainConcept MPEG Encoder stores it "user" templates in C:\Documents and Settings\<USER>\Application Data\MCMPEGEnc.

They are text based and have the .mef extension.

Hi Hans,

What error does the encoder report

-kwag

MPEG video encoding
MPEG PCM encoding, audio mode: 4
MPEG muxing
V130:Invalid video horizontal size (52 for DVD, should be 720, 704 or 352
P006:Invalid PCM audio sample rate (44100), should be 48000 or 96000
Error in converting:
The parameter is incorrect.

I based the KVCD template on an existing DVD template.
I tried it with an SVCD template and it seems to work, however, I have no idea if the encoding is as efficient as KSVCD. I'll try it and see what happens

The SVCD template does not really like the 528 width
Invalid width error (528 should be 480 for SVCD).

The DVD template does not like 528 either ...

So I'm trying 480x480 now ... (NTSC)

Wow, it's running pretty speedy when transcoding AVI -> MPEG2 (modified SVCD template using KSVCD settings). almost 1.5 times realtime! (on a P4, 2.8Ghz) 1.4 times to be precise ...

OK finished converting a movie, 1 hour and 48 minutes playback time, to "KSVCD", using MPEG Encoder;

@HansLuyten,

I'm curious about the picture quality even at 977MB. If it's
transcoding it could be a useful tool for converting DVD9 to
DVD5. It appears from your test, it only allows standard
VCD, SVCD and maybe DVD resolutions. Since it's accepting
KVCD GOP and Q-Matrix, plus bitrate adjustments we might
have a competor for Tmpgenc. Tmpgenc is great, but
slow.

-black prince

Tmpeg may be slow, but generally the filters you use slow it up even more. If you use faeryDust etc the frames came in slower than Tmpeg processes them. Main Concept sould be no quicker in this circumstance.

Jim

Well, the quality is very good! Just a bit too big for my 80min CDR's

I like the quality of MPEG Encoder, although TMPEnc is not bad either.
The only reason why I consider MPEG encoder is: SPEED. TMPEnc can be so very very very slow ... (hint: speed improvement tips are most welcome! )

I did manage to incorporate the bitrates and Q-Matrix of KVCD, however the GOP thingy ... well that part didn't work out yet (I'm getting a bit lost in the differences between the two template formats). So once I manage to include those as well, KVCD for MPEG Encoder should be just fine
Some help here would be very welcome!

Also; putting an entire movie on one CD in SVCD resolution is just fine for me, since none of the MPEG1 templates seem to work anyways on my DVD player (Mustek 520). Maybe sticking to a standard resolution might kill some of the issues with other DVD players.
