Noise filter in TMPGEnc

[aguinsburg]

Hello everyone. I captured VHS footage using passthrough in my DV camera. Is there any specific filter to apply encoding with TMPGEnc, specially for noise reduction? Settings?
Moreover, any advice to any other standard filter to apply?

Thanks a lot

The TMPGEnc Noise Reduction filter is S......L......O......W...... - you may want to look at convolution3D via AVISynth - guide here. This is much more powerful, does a better job IMO and is much, much faster. If you want to stick with TMPGEnc, I remember I used to only use settings of 1-20-1 or 2-40-2.

Or extraxt the audio from the (assuming) DV AVI file and use specialist filters in a dedicated audio editor like Goldwave, Audacity or SoundForge (there are others).

lordsmurf has some good stuff (including filters) on his site at www.digitalfaq.com

Good luck...

TMPG is definitely "slow" but time is relative.

If you encode overnight while you're asleep, there difference between 2 hours of encoding or 8 hours of encoding makes no matter.

I really enjoy the output of TMPG NR filters.

Daamon, see your Doctor!

Thanks Lordsmurf. Your comments are always precise and clear.

@ jimmalenko and aguinsburg - Yeah, yeah. OK - you got me. I get to wear the dunce's hat for a week...

TMPGenc filters are good but slow.
A faster alternative is to use virtualdub (for avisynth there are already comments from others).
I suggest a filter chaine like this: rmPAL (if the source is a PAL VHS tape), Resize (Lanczos, better do resizing before TMPGenc), MSU_Smart sharpen ("small overal" setting) or if your PC is slow use Virtualdub internal sharpness at 6, Static Noise Reduction ( 6 ) and Dynamic Noise Reduction ( 7 ).
That chaine produce better results than TMPGenc's internal noise filter, but much faster

Incidentally, the VirtualDub Temporal Smoother video noise reduction filter built into VDub is exactly the same as the noise reduction filter in TMPGEnc. The only difference is that Avery Lee's VDub Temporal Smoother runs about an order of magnitude faster. Plus, VDub has many other video noise reduction filter software plug-ins. Search the web for "virtualdub plugin" and you'll find tons of 'em.

As Satstorm remarked, the fastest and probably best way to do video noise reduction is to frameserve from VDub using a VDub noise reduction plugin and then go to TMPG or whatever MPEG-2 encoder you prefer to use. TMPGenc tends to be kind of slow in encoding MPEG-2 too, so you might want to check out QUenc or Mainconcept. I've foudn Mainconcept 1.41 to take about 1/3 the time of TMPG and produce files roughly 20% smaller with comparable bitrate VBR settings.
