Avisynth: STMedianFilter slowdown?
Hi
This is more than likely another daft question but... If I use the MA script as it stands with STMedianFilter the encoding speed is crippled. HCE for instance can run through at 40+ fps with that line commented out, if I leave it in it drops to ~3 fps which is a hugh drop. It also effects CCE which ends up with encoding times that make TMPGEnc look positively incredible, speed wise. I used to do encoding on an Athlon 2600+ and I do not recall this happening but I recently ditched that PC and replaced it with a Opteron box, memory isn't an issue (2gb) in case thats relevant, though just to make sure it wasn't an AMD thing I also tried this out on a spare 3ghz P4 Prescott PC and the same thing happens on that. Any ideas? For reference the version of the filter I have is 0.1.0.3 |
You probably have the memory alignement problem already reported.
Update your avisynth version (lastest is 2.5.6a) and if this does not work, add the parameter ",true" at the end of the crop line (do you have a crop line in your script ?) |
The version of Avisynth is 2.5.6a, the dll reports its version as 2.5.6 but I just re-downloaded and re-installed it to make sure, no change.
The script I'm using is the one below. It's essentially the MA script with the GripFit stuff removed and replaced with values obtained from PARanoia for a resizer and the borders. I've left the STMedianFilter line in place but commented out, as it stands this runs pretty quickly, if I uncomment the line.. slow becomes an understatement. Code:
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\dgdecode.dll") Thanks for the nudge in the right direction, much obliged to you :) |
You're welcome :)

Btw, what does STMedian filter does in layman terms ???

Probably shouldn't just followup this but anyway...
Anybody know of a decent alternative to STMedianFilter ? |
degrainmedian() by fizik, although I found it to be slightly slower than the STmedian.

Thankyou, I'll have a go with both :)
