My encoding speed

[WorldBook]

Hi

I have a prescott 2.8 ghz PC w 512 mb ram (PC3200).

These are the speeds I get:

1st pass: 33.87 fps

2nd pass: 24.92 fps

Are these speeds "okay"? or are they "slow"?

BTW here's the log

Also Autogk is an awesome tool :)
Thanks!

Hi.

Your speeds exceed mine (my processor speed is about 2.09 GHz). You're doin' okay.

Regards.

[manono]

Hi,

Yeah, those speeds look normal to me. You have a deinterlacer in there, which slows things down. If there was a full IVTC, it would be slower yet. With a Force Film (and therefore no deinterlacing required), it would be faster. And if you were able to Force Film, the total encoding time would decrease considerably, both because of the faster encoding speeds, and also because you'd then be encoding a 23.976fps .avi, instead of a 29.97fps .avi (fewer frames to encode).

And you're also encoding a full frame movie at 512x384. Since that resolution actually contains more pixels than most widescreen resolutions (for example 640x272), at different horizontal resolutions, and at different ARs, the relative encoding speeds would change.

Hi,

thanks for the replies!


BTW I neglected to mention that I conducted the entire encode from my dvd rw drive (instead of ripping the files to the harddrive), could that also be a bottleneck?

[manono]

Hi-

I don't know the answer to that one for sure (I don't think that makes a difference), as I don't do it that way. And neither should you. Encoding directly from the DVD-RW is a sure recipe for wearing it out before its time.

This can be a bottle neck in future. Sometimes, your DVDRW's "eye" may get dusted and then nothing will be read.:p

Another problem is with datatransfer rate...
HDDs are much faster than DVD drives. And if you are not using DMA, then slight CPU will be used up by the drive.;)

Once again, thanks for the insightful replies!
