2520 bitrate the highest SVCD's can get too?

[Pirate_King]

I use tmpgenc plus and was wondering if the highest bitrate an SVCD can do is 2520?

Hello,

You can go higher but than your making an XSVCD and not all dvd players can read those.

Also - squeezing more bitrate out of the svcd spec will reduce the amount of time you can fit onto a cdr if thats your destination (of course if your making svcd to fit onto dvd you'd be better off using halfd1 resolution {352x480 NTSC}).

Keep in mind that, that includes audio too. I use 2100 video & 224 audio and keep well within the limit

[midnightsun]

no.

Quote from this very site:

max 2600 kbit/sec MPEG-2 (Audio + Video bitrate max bitrate is 2778 kbit/s)

If you use a legit authoring application like I-Author or Philip's SVCD Tool Set, you'll get errors using 2400kbit/s for video and 224kbit/s for audio, same if you use bbmpeg to mux and choose the default SVCD template.

Keep the total combine bitrate under 2600 and you'll be in good shape.

The 2778 number includes mux overhead and other bits of data included in the stream.

ok
If 2600 is the recommended max for SVCD, then why wont tmpgenc plus let me select anything higher than 2520?

You have to load the unlock template first. That is just TMPGenc's suggested setting.

[Pirate_King]

Is the unlock template in my program or do I have to DL it? If I go beyond 2520 will there be a chance my DVD player wont play them?

[adam]

If you click load on the bottom right it should default to the directory where all the different templates are. Go into the directory labeled Extra and you should find and load the unlock.mcf template. This will make all locked options editable.

Honestly, I think the bitrate specifications for SVCD don't really matter except for actual SVCD players, as opposed to dvd players with SVCD support. The max bitrate actually supported by these players is just all over the map.

The higher you go the greater chance you will run into problems, but generally speaking most players will handle at least a little bit higher then the max 2778kbits. Make yourself a little test disk with tracks that increase in bitrate by 300-500kbits and see where your player tops out.

2520 is the max for most players. Beyond that trouble begins. Perhaps newer players have up'ed the level a little. Mine is 2520 as are most.

[adam]

Well virtually all players go to at least 2778kbits since that much is required by the standard. If it can't support that, it isn't compliant. Its an arbitrary limit imposed because SVCD players used cdroms which topped out at 2x at the time. With the loaders that are in SVCD compatible DVD players, the only real limit would be the firmware if they chose to stick to the specs regardless of the hardware's capabilities. I have found very few players with a strict limit under 2800kbits. Virtually all can at least hit 3MB's but of course everyone's mileage will vary.

If you really want to up the ante you can replace your loader with a DVD-ROM. This usually lets you go much higher. My Apex's would go up to 8MB's or so.

Older DVD players may not work all the way up to the SVCD compliant bitrate (so in a way, they are not truly SVCD compliant).

Original 1x DVD drives gave an equivalent of around 3x for CD media. This "should" be more than enough for SVCD but add to the fact that many of these DVD drives had difficult reading CD-R media as well (especially towards the edges of the discs), there were many reports of problems using the max bitrate.

This should no longer be an issue as most DVD drives apart from first gen drives will "spin up" when detecting a CD disc to provide better read performance.
