View Full Version : Good method to Scale down DVCProHD content.

I'm getting ready to squeeze down my DVCProHD films that I've been shooting into a DVD format. I've editied primarily in Premiere Pro and I've noticed that just squeezing them down in the Adobe Media Encoder produces results that are just "Allright". I'm guessing that the software scaling inside Adobe Media Encoder isn't that great.


I'm a little confused on the different types of filters and which ones would be good for my source content. Its a Film (with real people), shot on an HVX-200 (1280x1080 anamorphic 24P source content). I'm thinking my workflow for a high quality DVD transfer would be as follows:

Premiere Pro --> Debugmode Frameserver ---> AviSynth ----> Downscale to a 720x480 PNG sequence ---> Import into Premiere Pro to Encode Mpeg-2 DVD file

My question for you guys, which filters should I be using during the 1280x1080P downscale to 720x480 anamorphic, and what Median filters should I be using to make the image silky smooth without loosing high ammounts of detail?

why clutter the HD,
why back to Premiere?
i'd suggest that if you think Adobe preferential to HCenc,
you'd be wrong.
of course i'm not partial to mainconcept.

as it's 24p i don't see complications,
simple resizer. one with the desired sharpness, least artifacts.

if you want specific filtering suggestions,
post in the avisynth forum, with a very short sample clip.

exactly, no need to go back to premiere,

Premiere Pro --> Debugmode Frameserver ---> AviSynth ----> Downscale to a 720x480 (you don't need any file here) ----> HCenc ---> mpeg2 file

then

Premiere Pro --> export audio

then

muxman, do a DVD.

or

adobe enocore if you need to do any navigation and stuff.

My only problem with using HCenc is the fact that I may be selling this product, so I cannot use anything in my chain that isn't licensed.

Thats just the thing. I would be encoding Mpeg-2 in America, with an unlicensed Mpeg-2 encoder. Then turning around and selling that Mpeg-2 content on a DVD in America.
