People suddenly discover CVD....
A little Theory now:
DVD - Video, has 5 known resolutions:
CCIR 601 (720 X 576 (480)
D1 (702(4) X 576 (480)
D2 (352 X 576 (480)
D3 (720 X 288 (240) (No one use it)
D4 (352 X 288 (240)
So, CVDs, xSVCDs (like Sefy's SxVCD), xVCDs (like Sefy's SeVCD) and the typical VCD, are full compatible with DVD - Video.
Those resolutions are for BOTH mpeg 1 and mpeg 2.
DVD-Video "believes" that a mpeg 1 file, is simply a mpeg 2 with progressive picture file! Easy like that...
The gop stracture is the hidden compatibility issue:
DVD Video gop is limited in theory to 15 Pal/ 18 NTSC
In praxis, it is limited at 18 for Both Pal/NTSC
Long gops ain't supported. That's why TMPGenc splits big gops to smaller ones (only to new versions! So, forget old good 12/12a for those jobs!)
The best quality solution is: CVD with 48 khz sound!
The best General solution is: xSVCD with 48 Khz sound!
Both "formats" on CD-R today and on DVD-R tommorow, with no Re-encoding!

Anywayt, "Standard" SVCD is LESS compatible than your SxVCD for DVD-Rs!!!!
And once again, the most compatible CD format, is CVD, China Video Disc. If you want quality for your home media stuff, focus on this format!

Ah ha! So do you have an "official" CVD template for TMPGenc?
Just load the SVCD template of TMPGenc and unlock it!
Then, change the 480 X 576 (480) output resolution to 352 X 576 (480).
Hit encode and wait. The file is CVD!
Only the output resolution change!
In praxis, a 2 Pass CVD with 220min, 1900 average and 2620 Max, is quality equal with a SVCD with 220min, 2350 average and 2620 Max.
But with an average of 1900 you get more on one CD!
A CBR CVD @ 2520kb/s is much better looking a CBR SVCD @ 2520kb/s
I suggest 2 pass VBR, with an average 1900 for movies or 2200 for Video clips. Set the encoder to motion estimate search. For quality is about 90% of Higher/Highest quality, in much less time

Qu'en pensez-vous ?
qq1 a essayé ?
Apparemment CVD c du SVCD en 352 X 576.
Je me demande si avec la structure du SVCD et encodé pour l'audio à 48 KHz ça passe ?
car on aurait plus qu'à le copier plus tard sur DVD-R.
