Test results Positve! Downscale HDV to SD

Positive test Results with freeware Mpeg streamclip (Windows).

Import file / export as avi. / Use Apple dvcpro PAL/NTSC codec /
Quality slider / Frame blending , Better downscaling , Interlace / Deinterlace
Field dominance and all the frame size presets available.

Editing on Prem Pro 2 and Prospect / Downscale all my final avi's via
Steamclip before encoding with TMPG or Cinemacraft.

MPEG Streamclip is pretty close to VirtualDub in resizing quality. I did some tests today, and it looks sharper, but at the same time it has more compression artifacts than my VDub test file... Do you know what resizing filter is Streamclip using?

I've had very good results skipping the Vdub step and just taking my full HDV Cineform file into TMPEGEnc (Tsunami) and using that program to down rez a HDV file to a SD 16:9 DVD. It is much much better than Premier Pro's encoding to MPEG2 for DVD. I was using the Vdub step but don't see any real loss in quality by just skipping it and going right to TMPEGEnc. Thoughts? Anyone else had similar results?

Straight TMPG / V/Dub / & Streamclip

The route and reason i,am using Streamclip to resize //

My cineform avi's via streamclip and then encoded in cinemacraf.
Cinemacraft do not accept Cineform avi,s therefore i push my clips via
Mpeg steamclip where i can utilize the unlimited pass encoding /1-3 or four
times for real outstanding results. The timefactor / encoding speeds at
multipass encoding suits my workflow.

Cinemacraft allows me to do a scematic bitrate analysis of the encoded
footage afterwards where i can acces a problem area of the encoding
based on the encoding analysis to tweak and re encode that specific
section.

Herman, that sounds interesting. I didn't know you could do that with Cinemacraft - which version are you using?
