Just a simple little question (Yes/No)

[AP Enterprises Ltd]

Is 333.3kb/sec (1Mb/3sec) adequate quality for MPEG2 file of 480 x 480 w/ audio at MP2 224kb/sec Stereo?

(I'm aiming at 20MB/per min MPEG2 file for SVCD with those audio specs)

A File with your specs being built at 333.3KB/sec would be capturing at around variable bitrate of 2.250Kb/s. As you know the standard SVCD is around 2.400-2.600Kb/s. Fast action scenes or running water will obviously become quite blocky with your specifications. The question is, how do you personally define adequate?

No

Damn.

(Actually, I tried this myself but just wanted to see what you guys would say. I made a template (for TMPGEnc 12h) that turns out to be 333.3kb/sec and the output quality is not blocky at all. And it is a high-action scene too!!! I took exactly 3 seconds of a Pearl Harbor movie trailer, a part with the most action I could find. What it is is Ben Afleck's face cross-fades into a shot of a Japanese bomber plane thing flying over water at a high speed [this is where I thought it would get blocky because of all the shiny water moving, but it was just fine and dandy!], then it crossfades into someone running down a shiny hallway, then crossfades into a rotating shot around Kate Beckinsale looking at planes flying into the sunset. And the result? Just as good (to my eye) as the original.)

Want to know my template specs? Just say "Let me see your template specs".

P.S. - My max bitrate is at 2700kbps. So high action scenes shouldn't come out blocky...

Yes please share your specs in TMPGEnc for us.

Thanks, will try it out some time.

Addping padding does not do anything extra for you to give higher quality on low motion scenes. It's just for DVD players thatcan't play things that drop below the minimum bitrate - I've never seen one that needed this.
