Progressive Scan / IVTC Xbox/Xbox 360 Guide (NTSC TV SYSTEMSONLY)

Some Notes before You Begin

What is this “IVTC”?

IVTC means InVerse TeleCine. IVTC is the technique used to reversethe telecine process. Telecining is the conversion of 24fps (NTSC) film videointo 30fps (NTSC) video for broadcast. Inverse telecine is the reversal of thatprocess from 30fps broadcast video to 24fps. Thus Eliminating the Need forDe-Interlacing. Which In return Eliminates Interlaced Artifacts as well asCommon Stretch or Ghosting Anomalies that co-exist with De-interlacing Methods.

Benefits of IVTC:

Necessary Tools

You need:

Tsunami Encoder [www.tmpeg.com]

Please Note: there is somesoftware that "supposedly" can do IVTC Automatically, But it Only Uses the First fewSeconds to Make a Frame Pattern so if your Video Pattern Changes it chooses thewrong frame. (or if you drop frames when your encoding), Also Tsunami encoderhas an "Auto IVTC". This automated IVTC scans your video by theframes Flicker values And you can review the Video and Make Changes as Needed

InverseTelecine the Video

FirstGo to the Settings Menu and Check then Double Click the Inverse Telecine Line.

Which Will bring Up this Menu:

-Press the Clear button. Thiswill reset any previous IVTC settings.

-Click The Drop Down Menu Under the "Check" Button, and Choose "30 fps"

-Scroll Right Using the LowerArrow.. You’ll Notice You Have Some Progressive And Some Interlaced VideoFrames:

Examples, the Progressive frame isOn the Top and the Interlaced frame is on the bottom.

First Notice the Lines From theMotion On the spoiler, car and background/track in the Top Frame.

And the Lower Frame does not exhibit these effects.

Now that You Know whatProgressive and Interlaced Look like. Now You Have to Find the Frame Sequence.

Most Videos Use Frame Sequenceof “101010” If rendered in 30 frames/sec (ie Forza Motorsport 2 Replay)(1=Progressiveand 0=Interlaced),

Find the First Progressive Frameand Left Click to High Light it,

If It Is Progressive, Right Clickon the First Frame and Choose “Deal After this Frame According to SelectedPattern”

Which Brings Up this Little Box.

Enter the Pattern Into the Boxand Click OK (again 1= Progressive [frames you want to keep] and 0=Interlace[frames you want to discard]

After You Enter the Pattern.Using the Lower Right Arrow Scroll Forward frame By Frame and Check to ensurethey are progressive.

Keep Scrolling until you hit aInterlaced Frame, which is either a scene change (or camera angle change) or where you dropped a frameduring capturing.

After You Get to the nextInterlaced Frame Go Forward Until You Find the Next Progressive Frame (Which isusually right after) and Highlight that One and Right Click and Deal thePattern Again. (Again usually “101010” for 30 Frames/Sec Games”) (this will not affect theframes you already set Prior to the Interlaced Frame.

Keep Repeating All the Waythrough the Video, depending on the video you may only have to set the framepattern once, twice or Up to 30 times.

Also Every Few Scenes Hit theCheck Button to Make Sure Your Audio And Video Is Synced. If It Loses Sync itwill take you to the frame where it occurs. And to fix it look at the Bottom ofthe From on the Top Bar and it will say “Estimated” and “Current” If Current IsHigher than Estimated De-Select that frame and check again. If Current is lowerthan Estimated Go Back a few frames and Select some more Progressive Frames andcheck again.

After You Set the Frames Clickthe OK Button On the Top Left of the IVTC main Setting Box and You Drop Back tothe main Settings Windows Of Tsunami,

I know Cool Edit MP3's Work in WMEncoder, I'm not sure if other programs work though.
