I won Ton Staassen contest in April 2001, it was to make the best VCD or SVCD from a Hi8 footage captured with a Pinnacle Studio DC10.
Proposed by Ton Staassen (Nederlands) to compare results related to encoding parameters used by other people, the contest is still opened. You can take you chance and beat the best VCD and SVCD of the moment. The Internet link isn't permanently active because of the huge traffic due to the success of this competition hosted by a free but limited Dutch provider: VCD COMPETITION.
Ton has set a reference AVI clip, a 5 seconds outdoor scene, filmed with an Hi8 camcorder and captured with a Pinnacle Studio DC10 then compressed to MJPEG format to fit in reasonable file size with a fair quality.
Submission with clips made with trial version of PICVideo or Main Concept codecs (which overlay their trademarks) are qualified.
I am part of the jury but I haven't join the final round for SVCD (just normal since I've submitted for this contest).
I've made a lot of tests with TMPG, CCE and LSX encoders but I never got a satisfying result. Therefore, I've set a simple process to analyze and encode the video clip:
NBR) with TMPG and my XSVCD template
for PC: tmpgxpc.zipNBR down to 4MbpsBR is measured with Bitrate Viewer, available
from its home page. My XSVCD for PC template is a completely unlocked template
set up to 9Mbps (close to DVD standard at 9.8Mbps).
I've encoded the clip with TMPG/tmpgxpc and then I've opened it into Bitrate
Viewer which gave the NBR around 8Mbps. It's very high, due to
a high level of details of the footage. MPEG artifacts are mainly visible in
the back of the mother on the bicycle.
So I have to remove some details, in other words to smooth the picture and we have the smoother filter (an internal VirtualDUB filter).
My solution:
The VirtualDUB process is:
discard field 1-4%precise bicubic) 768x288 to 480x57610)The processing settings are available in presmoothplus.zip, you should be able to load it in VirtualDUB. I've choose to recompress with Huffyuv to avoid compression artifacts.
The new NBR I got from the modified clip is from 4 to 5 Mbps,
that's values that TMPG cab handle for SVCD format.
I've fine tuned my usual SVCD template (progressive video) :
2 pass VBR at 2520 average and 2680 maxsoften block noise audio bit rate at 64Kbps (minimum for SVCD standard)After encoding I've checked the NBR again : 2102 average
and 2684 max.
I've burnt the SVCD on Windows 2000 Professional system with Nero 5.0.4.8 and played on PC (with WinDVD 2000) and on my TV set Philips 70cm (4:3). Picture is good on both .
