Converting PAL (H264) to NTSC

I notice that BeLight / BeSweet has Soundtouch / stretch built in, so I adjusted the rate to the figure you listed, but it now seems to be too slow. Are you sure you're using the -soundtouch(..) switches? BeSweet also has another way to change the rate, using the -ota(..) switches. I don't know the difference between the two methods.

How did you calculate that rate in the first place? I'm assuming it is something to do with the 4% speed difference, but other than that...
23.976/25 x 100% = 95.904%

This is a slowdown of 4.096%.

I replied yesterday but the forum seems to have eaten my post.

There's nothing wrong with that approach; I've done the same thing myself with heavy processing scripts.

The only thing to watch out for is that colourspace conversions are not lossless. Although it's only a theoretical loss and not something I've ever noticed in practice, it's probably still a good idea to avoid unnecessary colourspace conversions. What this means is that if the output from your script is YV12, make sure that lagarith is configured to use YV12 format. Huffyuv can only compress YUY2 or RGB.

BTW I finally managed to download your sample. There is some faint ghosting visible on the cartoon segments, but I suspect (without actually seeing the source) that's probably the best you can do with it.

It looks very good. I'll have to dig out the Cyber-EFX version I downloaded and make some comparisons.

Did you want to keep the same pitch (timestretch), or just change the playback rate? The latter is easier, and less likely to produce any artefacts - also if the audio was originally sped up to sync with 25fps then slowing it down will restore the correct pitch.

I've found the SoundTouch program is an easy way to change audio speed, and I haven't noticed any choppiness.

A simple command line is all you need:

soundstretch input.wav output.wav -rate=-4.096

I think all the laserdisc transfers (SC, DC & PAL) have more vertical detail than the GOUT DVD (because of that vertical blur effect on the picture). However, the DVD wins out when you look at the horizontal detail.

I imagine that the X0 capture has better vertical detail too, and if the horizontal detail is similar to the DVD, then you're doing well.

http://www.originaltrilogy.com/forum/messageview.cfm?catid=9&threadid=6848A problem with horizontal field movement during the telecine process caused 'jaggies' in the Definitive Collection transfer. Instead of fixing this properly, i.e. making a sub-pixel horizontal adjustment between the fields, the DVD has been mastered with a vertical blur to mask the jaggie effect.

Info Wanted: Another audio mix thread
Time
People, please read our FAQ - especially points 3 and 8b.

Taking the GOUT DVD and adding alternative sound mixes (or converting to anamorphic, adding custom menus, whatever) does not count as a fan edit, nor as a preservation effort. The separate audio files are available to download, the GOUT DVDs are official releases and are/were available to buy.

Although we have no problems with you making posts about your own "custom" DVDs that you've made, please refrain from discussing distribution of such discs on the forum. Thanks.

Doctor M, is the interlacing the sort of thing that was discussed in this thread?

If so, you might be able to process it using an AVISynth function called Restore24. However, the threads on Doom9 confused the hell out of me; I think it will take quite a bit of reading to work out exactly how this function is supposed to work.

How to convert Xvid -> DVD?

Why not? It would make things much easier for you. If you don't want to replace your main player, why don't you get a cheapo box to use as a second player?

Alternatively, many people use a chipped Xbox as a media player. This is a good solution too, especially if it's linked up to a home network.

Or if your PC is in the same room as the TV, just hook it up to a cable from your video card's TV-out.

Converting to MPEG-2 for DVD should be the last resort.

Info: The Making of The Empire Strikes Back (Michel Parbot)
Time
2006 was of course the year in which the original trilogy was once again released on DVD, only this time with the original theatrical versions as "bonus" discs.

And talking of coin-ops:
1983 Star Wars, Atari
1984 Return of the Jedi, Atari
1985 The Empire Strikes Back, Atari (conversion kit for the 1983 Star Wars cabinet)
1993 Star Wars Arcade, Sega
1998 Star Wars Trilogy Arcade, Sega
2000 Star Wars Racer Arcade, Sega

Converting PAL (H264) to NTSC
Time
It's useful to have the relevant information here for future reference, thanks.

Couple of additional notes, bearing in mind that we are all still learning these methods (I hadn't attempted an H.264 conversion before DJ asked me for help, so most of this is based on my experiences with the sample he sent me).

The reason for using the xport Transport Stream Demuxer (http://www.w6rz.net/xport.zip) is that it will start the video from the first key frame, and trim the audio to match. This alleviates the need for trial-and-error to obtain an audio delay when re-muxing your converted video.

Reading AVC (H.264) streams into AVISynth:

There are two mechanisms by which AVISynth can read H.264-encoded files: DirectShow or Video for Windows (VfW).

To use DirectShow, you must have a DirectShow decoding filter present on your system, for example, the Cyberlink H264 decoder that is included with PowerDVD 7. If you can play H264 files in Windows Media Player, then you should be able to read them in AVISynth. It's also recommended that you use AVISynth 2.5.7 or later, because the DirectShowSource() code was improved in this version.

I found that the output from the AVS script was the wrong length (too long, because some of the video was repeated at the end). I don't know why this happened, but a possible workaround is to use the framecount option in DSS, i.e. DirectShowSource("file", framecount=123456).

The alternative is to put the H264 stream into an AVI file using avc2avi_mod (http://sourceforge.net/projects/avc2avi). In order for AVISynth to read the file using AVISource() you will need an VfW H.264 decoder. I used ffdshow; you need to go into the configuration and enable H.264 decoding (libavcodec).

Star Wars: Classic Edition 2.0 NEW from Ocpmovie (Released)
Time
From Page 2:

So I guess I have to actually make the dual layer version a little more full of value.

I've included two special extras on the second version.

The first is an AVI file of The Daily Show and The Colbert Report from October 11th -- George Lucas was the guest star on The Colbert Report, as Stephen presented the finale to his epic "Green Screen Challenge" competition. My friend Bonnie Rose won the contest. Star Wars references abound including an appearance by Jar Jar Binks.

The second is a batch of DVD-quality M2V/AC3/AIFF files which present a better quality copy of the Star Wars skit from the Donny and Marie show, back in 1977. If you have my Return of the Ewok DVD you've seen this -- at only 12 minutes it's much shorter than the Star Wars Holiday Special, but somehow manages to be much worse ... It's the worst Star Wars related thing I've ever seen, and you have to love it for that, particularly if you enjoy horribleness like the Holiday Special. Donny and Marie Osmond play Luke and Leia - definitely the first time Luke and Leia were ever shown as brother and sister in an incestuous relationship. 6 years ahead of your time, guys. Redd Foxx is Obi-Wan, Kris Kristofferson is Han, Paul Lynde is Tarkin, Thurl Ravenscroft (Tony the Tiger) is Darth Vader, the Ice Angels are the stormtroopers on skates, Anthony Daniels is C-3PO, and we've got R2-D2 and Chewbacca. The whole thing is horrifying.

And this copy is better quality than was on Return of the Ewok. I have the entire show but due to disc space issues I'm only including the Star Wars related material - although more than was on Return of the Ewok.

Some people may not be able to play these files - the video is in M2V format and the sound is in both AIFF and AC3 formats. Newer versions of Quicktime will understand it though, and so will VLC. I present it in this format so that it will be incredibly easy to burn to your fan DVDs - M2V/AC3 is of course the traditional DVD video format.


So, that's how to tell whether you've got the SLIGHTLY altered Dual Layer version. A couple of weird extras.

Enjoy.
