Use WinTV-PVR hardware to encode MPEG2 ?

[Guest]

Archived from groups: rec.video.desktop (More info?)

I'm trying to re-encode 3.5 hours of MPEG2 video for burning onto a DVD (the
video needs cropped, resized, and cleaned up). I've tried TMPGENC Xpress but
it was going to take 54 hours! I was wondering if I could use the hardware
encoder on my WinTV PVR-250 to do the job instead. Is this an option, or is
the encoding hardware strongly tied to the PVR software?

Another related question... why aren't MPEG encoders available as Windows
codecs? If I install DivX, for instance, it can be used with most video
encoding tools. MPEG encoders, however, seem tied to one or two client
applications.

You don't mention the specifications of your system. 54/3.5
seems out of line for the TMPGEnc 3.0 Encoder. There are
faster encoders (including both the free and 2.5 TMPGEnc)
but I would expect that you have other problems to address.

Luck;

Once I turned off noise reduction my time dropped to 12.5 hours, which is a
lot better. Still, my original question stands.

Using the hardware of the PVR-250 probably isn't possible if you do
not use the tuner or the input connection, it probably isn't designed
to do so, otherwise you could have expected software to be released to
make it possible.

Ympeg appears to be a mpeg-1/2 encoder that follows 'Video for
Windows' (vfw) specifications, so it can be used by VirtualDub (like
DivX, Xvid etc.). Why others can't be used in this way seems to have
a specific technical reason, I can't remember the details.
