Here's how to de-interlace the Media 100 output files for NTSC.

First, you'll need the iFinish transcoder from Media 100's website. If the link is dead, go to the home page and click software downloads then look for the iFinish transcoder.

"The iFinish Transcoder allows anyone with a compatible Windows® NT, 2000 or XP computer to open and view media from an iFinish system compressed with the Media 100 codec, without having iFinish hardware installed. The iFinish Transcoder supports square and non-square pixels - NTSC 640 x 480, NTSC 720 x 486, PAL 768 x 576, and PAL 720 x 576."

Next, Export from Media 100 using the Media 100 codec. There are few options, (I set the quality one notch below highest.) choose Media 100 NTSC HDR (or PAL if that's the source format) and do the export with the creator set to Apple Movie Player. Check the Audio box too, unless you want a silent movie. You must have the Whole Deal or other dongle that enables High Data Rate to use the HDR codec export.

Now you wait, a lot. ;) It will process all the video clips in turn that are in the program or the range you selected, then it will process the audio and multiplex them together.

If you haven't already checked the Exporting page, do so now to see how to move the exported video to your PC.

You should have Tsunami Plus installed with the Quicktime reader plugin for the next step.

Here's a walkthrough for creating a 480x480 MPEG2 video ready for burning to Super Video CD using a program like Nero Burning ROM.
The original source is a full screen program captured from a NTSC VHS tape.

Launch Tsunami and in the Project Wizard, select NTSC under Super Video CD.
Choose VBR Standard Format.
Click Next, then Browse and select your Quicktime video file.
Set Video type: to Interlace, Field order: Top field first (field A), Aspect ratio: 4:3 display, Content of video: Video movie.
Click Next, then check Clip frame and scroll through the video to see if any lines from the Vertical Blanking Interval have been captured. These will be visible as black areas with white dashes that jitter back and forth.
Check the mask boxes for top and/or bottom where there are VBI lines or other noise. Also check left or right if there is noise or fuzzy edges.
Now enter numbers in the fields or use the spinner controls to advance one line at a time until the VBI lines or noise is just covered. The default mask color is black, but you can change that if you wish. This masking will result in better video quality because the encoder will have a pure color to compress in the masked areas instead of jittering VBI lines or fuzzy noise. If your source was letterboxed, cover the letterbox bars completely with the mask. Click OK.
Click the Other Settings button.
Set Rate control mode to 2-pass VBR. This will be slower but will much improve the output!
Set Encode mode to Non interlace. If you leave this on Interlace, the deinterlace settings won't do anything.
Click the Advanced tab and make sure the settings are as below.

Video source type:    interlace
Field order:          top field first
Source aspect ratio:  4:3
Video arrange method: full screen
Deinterlace:          Even-Odd field, (field, adaption)

To change the Deinterlace option, doubleclick it, select the method, ensure the Enable filter box is checked then click OK.
You'll be back on Advanced and Deinterlace will be checked.
Click OK, then Next. (Assuming you don't want to just encode part of your video, that's the Source range option.)

On this page, select CD-R 74min or 80min (VCD/SVCD) then check Auto setting which will select a video bitrate to make the video fit 99.99% of the disc size. If you're using 90 minute blanks you'll have to select Unknown media and manually set the estimated file size to fit.
Yes, 786.91 megabytes will fit on a 703 megabyte CD-R! How? SVCD uses Mode 2/XA which uses fewer error correction bits per block so more data will fit.

Click Next then choose where to output the MPEG2 video and a filename for it.
Click OK and it will pop up a box saying the file does not exist, do you want to create it? Click OK and you're off and encoding.
Check the Shut down after finish encoding box, turn off your monitor and go to bed. :)

Transcoder note: The information file in the ZIP says "Note: The iFinish Transcoder does not provide real-time playback." Don't believe that! On my Athlon XP 2000+ (overclocked slightly with a 140Mhz CPU bus speed) it most certainly does playback in realtime with the Media 100 Codec. It's very smooth, unlike when I tried MJPEG-A or MJPEG-B. However, the Media 100 codec produces LARGE FILES You'll definately want your work drive to be NTFS, not FAT32. My current project exported a 5,629,098 KB file, plus the 1,433 KB .qtr resource fork file. (You definately want to be running Mac OS 9.1 and HFS+ on your NuBus Media 100 system!)
