Fastest Bitrate Conversion For Mpeg1?

[leebo]

I just bought a Pinnacle Moviebox USB to capture directly to Mpeg1. A user on Pinnacles forum who had one confirmed for me that you could set the capture rate to 700kbps, which I needed, so I bought one.

Unfortunatly, although the software lets you set the capture rate to 700kbps, the device seems to be incapable of that rate, defaulting to 4000kbps!

So the best I can do is capture at VCD (1150kbps) and convert.

So my question is, what program does the fastest bitrate conversion? Using DVDShrink for DVD's, I'm spoiled at the transcode speed. A full DVD can be shrunk in a few minutes.

But using Pinnacle Studio 9, converting two hours of VCD quality video takes 40 minutes. Does anyone know of a faster software for doing what I want?

Standard mpeg-1 uses a fixed bitrate of 1150 kbps. There is no other bitrate in the plain vanilla VCD mpeg-1 standard. If you want to use another higher bitrate, and of course you can if you choose TMPGenc or Procoder or Mainconcept or CCE, your mpeg-1 file will not be VCD-compatible and will not play back as a standard VCD.

Using TMPGenc and Procoder and Mainconcept I've experimented with btirates as high as 8000 kpbs in mpeg-1. Mainconcept does by far the fastest mpeg-1 conversion of the group, with TMPGenc far in the rear for conversion time. However, when you get beyond 1150 kbps mpeg-1 you're now in the realm of XVCD, a non-standard format that might or might not play back on your particular DVD player. Some DVD players accept XVCDs, others don't. No way to tell.

What I've found by experimenting with high-bitrate mpeg-1s is that the mpeg-2 protocol is much more efficient. Using TMPGenc or Procoder or Mainconcept, the resulting filesize for the same CBR bitrate in MPEG-2 is always smaller than with MPEG-1. So if I do a fixed-bitrate 5000 352 x 240 mpeg-1, it comes out bigger and usually looks worse than if I do a fixed-bitrate 5000 352 x 240 mpeg-2.

High-bitrate mpeg-1 videos used to be popular back in the day before DVD burners and DVD-R media were cheap, but there's not much point in nowadays. mpeg-2 is a better video format, and H.264 even better than mpeg-2.

Thanks for the effort, but you post has absolutly NOTHING to do with my question!!!

Had you actually read my post, you'd see in the second sentence, I said I needed mpeg1 at 700 kbps. Much LOWER than VCD quality. and I'm looking for speed, not quality.

Good luck with your ADD though.

Good luck with your ADD though.

Maybe you should read "What is VCD" before jumping on people that are trying to help you.

From your past post I think this question was answered.

main concept would be the fastest most likely for this .. though a faster machine would help ..



reading from one drive and writting to another will help greatly as will dual cpu or dual core and fast drives

Where in my original post did I state I wanted to convert a video into a VCD?

I said the lowest bitrate the device I bought could capture at is 1150kbps - I need a device to capture at 700kbps, or software that can convert 1150kbps to 700kbps.

BJ_M apparently had no problem understanding. I don't see why it was so difficult. I responded to spectroelectro's post the way I did because he answered a question I never asked.

I really do appriciate help, but if I ask "Why is the sky blue?" and someone answers "Drive safely", they're asking for it, IMO.

[canadateck]

You mention (VCD) MPEG1,I think that is where the confusion came in.

And I guess BJ_M just guessed your "Computer Details".

who would have thought a better computer with better software would make things go "Faster"?


Good Luck.

Well, in my original post, I said:

So the best I can do is capture at VCD (1150kbps) and convert.

Convert to what? Oh yeah. 700kbps, which I stated in my original post. Hardly sounds like VCD to me.

I don't know how I could have been clearer, other than to draw pictures. Anyway, sorry to step on toes.


Guess I'll submit another post asking about external capture devices.

ok - question asked and answered ..


lets drop it everyone ... ok ?
