Finished these back in the middle of June and forgot about them. I just posted over at myspleen.
Here are the details:
I present here a collection of the four Star Wars Special Edition Trailers.
The video for Trailers B, C, and D was ripped from the '97 Laserdisc editions, while the four audio tracks come from various sources. The most important track is the original Theatrical 5.1 Mix decoded from theatrical DTS discs provided by Jetrell Fo on OT.com. The other mixes are discussed below. Again, much thanks goes to Jetrell Fo. I hope everyone enjoys these, as I think they are the best Star Wars Trailers that exist.
Technical Details:
VIDEO
=============================================================
1. Captured the 97 SE trailers from three different LD copies, using a Hauppauge WinTV HVR 2250, in VirtualDub.
2. IVTC and combined the captures in Avisynth using a modified version of the Median script posted to originaltrilogy.com by user mysycamore.
3. Resized to 720p resolution using Spline64Resize filter.
4. Encoded to h264 using Adobe Media Encoder CS6 (Blu Ray Spec)
AUDIO Track 1 - Theatrical DTS Surround
=============================================================
(Decode to WAV)
1. Convert to 5 mono wavs (L, R, C, Ls, Rs) with apt-x100 DTS Decoder in winamp. (Produces 5 wavs @ 44.1kHz/16bit)
2. Save to 5 mono 24 bit wavs with no dither (padded wit zeros) using Weiss Saracon.
(Convert to 23.976 fps)
3. Interpret Sampling Rate as 44,056Hz using Adobe Audition CS6.
4. Upsample all tracks to 48kHz using Izotope RX 2 Advanced (64Bit).
(LFE Channel)
5. Create Stereo wav with Ls and Rs Channels using Wavewizard.
6. Apply Flat Lowpass Filter (Analog Mode) @ 80Hz with Q=24, sum to mono using Izotope Ozone 5 Mastering mode.
7. Save as 24 bit mono wav with 48kHz sampling rate.
(Surround Channels)
8. Attenuate by -3dB, then apply Flat Highpass Filter (Analog Mode) @ 80Hz with Q=24 using Izotope Ozone 5 EQ mode.
9. Save as 24 bit stereo wav with 48kHz sampling rate.
10. Split to 2 mono wavs with Wavewizard.
(Combine Tracks)
9. Syncronize Tracks in Adobe Audition CS6.
10. Save as 24 bit, 48kHz, 5.1 channel wav.
11. Encode to DTS-HD MA using DTS HD Encoder Suite
AUDIO Track 2 - Theatrical DTS Downmixed to Dolby Stereo
=============================================================
(Decode to WAV)
1. Convert to stereo wav with apt-x100 DTS Decoder in winamp. Use Dolby Surround/ProLogic settings.
2. Convert to 24bit wav with no dither (padded wit zeros) using Weiss Saracon.
(Convert to 23.976 fps)
3. Interpret Sampling Rate as 44,056Hz using Adobe Audition CS6.
4. Resample to 44.1kHz using Izotope RX 2 Advanced (64Bit).
5. Dither to 16 bit using TPDF mode in Weiss Saracon.
AUDIO Track 3 - Laserdisc Stereo PCM
=============================================================
1. 16bit, 44.1kHz, Stereo LPCM Captured 3 times to ensure bit accuracy.
AUDIO Track 4 - Laserdisc Dolby Stereo AC3
=============================================================
1. Dolby AC3 track captured as 16bit 48kHz Dolby Digital Wav.
2. DDWAV decoded using BeSplit.
3. Synced using delay settings when muxing.
TRAILER A
=============================================================
Trailer A was included on the Official 2004 DVD Bonus DVD, and has been included here for completeness. The video has been upscaled to 720p using Spline64Resize and re-encoded to h264 using Adobe Media Encoder CS6. The audio is the stereo ac3 present on the original DVD.
BONUS
=============================================================
I've included the Behind the Scenes Featurette from the 1997 SE Laserdiscs here as a bonus. The video was processed in the same way as the trailers with the exception of the IVTC step. Since the video is a mixture of film and video sources, IVTC will work fine with the film content, but will eliminate fields from the video portions. I tried various IVTC methods, but found that the interlaced video actually looked the best on my TV. You may have different results, but this was my justification. The video is presented here at the original 480i resolution. I've included both the Laserdisc PCM and Dolby Stereo AC3 tracks.
