Q's about capture speed.

I am using VideoStudio 7 to capture and then convert from Huffyuv to MPG2 (VBR-8000 720*480)
I have no problem and quality is good.

It takes about 2 hours to encode a 50 minutes file. I have a AthlonXP 2000+, 1Gig memory, and use 2 HD 7200RPM.

Is this normal speed?

Thanks

that sounds okay.. some encoders are faster than others.

TMPG takes about 4-5x the material length (ie 4 hours for a 1 hour movie), with excellent quality.

MainConcept 1.3 only took 1.8x, but I didn't like the quality of the output file. so until I find a better encoder, I'll take quality over speed.

but 2x sounds decent, if you like the quality you're getting.

CCE is real-time...

CBR is 1X and N-pass VBR is (N+1)X with same excellent quality as TMPGEnc. (In CCE N-passes is actually [N+1] passes because the first pass creates the VAF file, and then it does N encoding passes).

TMPGEnc is more flexible, CCE is faster, both are excellent. TMPGEnc is the winner for value/$$$.

I also tried MainConcept but was not impressed with the results. Too grainy for my taste.

CCE is real-time...

even on my PII/350?



that's one hell of a program....

Do we know what encoder Video Studio 7 is using?

Thanks!

Oops, good point housepig!

I should have been more specific. CCE is real-time on MY system which has:

- 2.4 GHz Intel P4
- 512 MB RAM
- 200 GB HDD

So, no I doubt it would be real-time on a P2/350.

Also, MainConcept on my system was essentially real-time but as I said, the quality was not great.

It uses the mainconcept encoding engine.

Huffyuv is very slow to decode, which is the major slow down. MJPEG decompresses faster, but can have less quality than Huffyuv.

I'd still suggest using huffyuv. It captures fairly easy with minimal dropped frames. On my 2.4GHz P4, I can get 720x480 and suffer maybe 1 dropped frame per 15 minutes. The only drawback is Huffyuv is a real space hog, easily eating about a Gig per minute.

Mjpeg isn't quite as good quality wise and could be considered if the hard drive space is tight or if you're having trouble with Huffyuv.

IIRC when I used TMPGEnc to convert to mpg2 (for DVD) it usually take me about 2-3 minutes for every 1 minute of captured video.
