Here is some of the technical/background information on how I did this restoration.
I had four different sources of the movie to work from (collected over some years):
- The 2002 restored PAL German DVD version (not Moroder's version at all). This was used for almost all of the restored video sequences.
- My original VHS recording of Moroder's version which I made in the 80s. This is a PAL version with very poor mono sound. This version was used for some colour reference only.
- A Greek 'commercial' PAL DVD release of Moroder's movie. This DVD version is actually a video rip. Its video sharpness isn't great (nor is the audio quality) but it has good colour. This version was used for colour reference, some of the Moroder special composite elements and extra footage.
- An NTSC DVD version ripped from the Moroder laserdisc. This has good video sharpness but terrible colour quality. This version was used for the restored soundtrack, which was uncompressed PCM.
I started by exporting the Greek DVD in a Quicktime format (including audio) and loaded this as my base reference track, as a PAL edit. I exported the restored version in a lossless Quicktime format and started to rebuild the video over the reference on a shot-for-shot basis. I chose the PAL version as this is the source version that the German restored version was released in. I didn't want an NTSC conversion of that original.
The PAL version is in 720 x 576 25 fps progressive format. The final NTSC conversion of that is 720 x 480 23.97 fps progressive, so the frame size is shrunk from the PAL version and the frame rate is lower also, meaning higher quality overall. Going from PAL source to NTSC edit (and then back to to PAL) would be bad. The NTSC version is progressive because the PAL version is. Some DVD players may do 3:2 pull-up and interlace the output but a good player/TV should handle 24 fps natively.
Due to the difference in footage and takes available on the 2002 restored DVD, there are some minor shot variations and cut changes. Where possible, the cuts match the original Moroder version to the frame.
Another issue was the differing frame rates. The Moroder version uses old analogue technology to alter the frame rates of the original footage (there's a whole debate about what the 'true' frame frame should be). What I did was match in start and end of a shot and then use digital time remapping to make the restored footage duration match the Moroder version. I have done this without frame interpolation, so every frame is nice and sharp. Sure, sometimes the motion isn't as smooth as it could be, but let's face it, the motion isn't that great in the 1927 footage to start with!
Some shots from the Moroder version had modern SFX and these have been rebuilt using the restored elements where possible. For example, the moving clouds in the background of the stadium for the 'chosen few' (near the start of the movie) come from the VHS rip Moroder version, while the foreground comes from the restored DVD footage.
The whole movie was re-edited in it's original black and white, before I started adding the colour tints.
Because there are three different versions of the colour tints Moroder used on my three sources, I have redesigned the colour tints throughout the movie, based on those three versions. The worker's city has one consistent tint, the cityscapes another, the underground tunnels another, etc. This makes the colour tinting very cohesive, and in fact I've dropped in the correct 'location' tints that weren't there in the original moroder version.
For example, when we cut away from Maria entering the Worker's City near the end of the movie, to the big machines blowing up, Maria has the Worker's City tint and the machines have the Machine level tint. These 'locational' tint changes don't seem to be honored very well in the original Moroder versions.
All of the inter-titles and subtitles have been rebuilt from scratch - including the opening title notes. You can check the quality on another post on the
Opening Titles.
The soundtrack which was taken from the PCM uncompressed laserdisc version was digitally cleaned up and synchronised with the newly restored movie. I also repaired a soundtrack error - I suspect that was where the original laserdisc needed to be turned over!
The unfortunate side-effect of doing this restoration is I'm far too familiar with this movie now and could quite happily never see it again for some time :-)
The final edit was then exported via a professional DVD MPEG encoder at the highest bit-rate I could fit on a standard DVD-R disc, along with the soundtrack at a high 320 Kbps. I considered using uncompressed PCM audio, but with only around 4.4 GB to play with, I'd rather use the space for better video quality.
There are no 'extras', however there is a bit left over and I may well add an low bitrate Editor's commentary track. Not sure yet ... why not tell me if you like the idea?
I also have the single release of 'Rotwang's Party', which was the b-side of Freddie Mercury's 'Love Kills'. I have sampled and cleaned up this hard-to-find track and would like to include it but I'm wondering what to do with it.
