What are you using to compress the video for storage on the Lib?
Thanks

Well... for compression and transcoding, the program I found worked for me
to accomplish this task was TEMPGEnc Plus 2.5. But the whole process of
transcoding a 16:9 widescreen MPEG-2 file to a customized VCD, as you may
have check out in that test sample, involved a few other free video
utilites. But the only onea I seem to need at this point are AVISynth and
DGIndex, which came as a part of the AutoGK XVid/DivX installation available
at: www.doom9.org
I got help figuring out the process on the Doom9 forums where someone came
up with an AVISynth .avs file to load into TMPGEnc that I've been modifying
in the past couple of days for processing other DVD files. It's a simple
ASCII file made in a basic text editor, and saved with the .avs extension.
Here it is:
-------------------------------------
LoadPlugin("C:\Program Files\AviSynth 2.5\pluginsDGDecode.dll")
Video=mpeg2source("X:\ <enter path here> \<DGIndex project file>.d2v")
Audio=directshowsource("X:\ <enter path here> \<DGIndex produced audio
file>..ac3")
Audiodub(Video,Audio)
DelayAudio(0.066)
crop(0,60,718,362)
lanczosresize(384,160)
-------------------------------------
Once the 1st line is configured for the DGDecode.dll file, the only lines
that seem to need changing on a regular basis are #2 . When you load
your widescreen MPEG-2 file made from a DVD's VOB files into DGIndex, and
save the project, DGIndex outputs a series of files. The project itself is
saved as a .d2v file. DVD audio tracks are usually save as Dolby .ac3
files, and the largest is usually the main audio file.
So you can alter the path in line #2 to the .d2v file DGIndex produced from
the source MPEG-2 file, and the path in line #3 to the main .ac3 audio file
DGIndex produced (demuxed {separated & audio}from the source).
Then in TMPGEnc, you load the .avs file, load the videocd (ntscfilm)
template, load the unlock template, under the video tab change the video
size to 384x160 and the aspect ratio to 1:1 (VGA). Then change the audio
options, rate control mode and motion search precision if you want. Ok it,
and press start.
One other note, there seemed to be an issue with the source video not being
interlaced. This is all really new to me, and I expect not too many people
on the list here are really that familiar with many of the very complicated
video components. As the source video I produced from the DVD VOB files was
progressive instead of interlaced, I was told to set DGIndex to "Forced
film" in the Video>Field Operation menu before saving the project.
If you're interested in any more on all this I may be able to provide,
contact me off list (unless there's any other interest from list members),
and I'll be glad to help where I can.
