Neoscene - Mac and PC Workflow - One Step Pulldown Removal

[Isaac_Brody]

Neoscene now properly performs an inverse pulldown on GH1 footage and upsamples chroma to 4:2:2 on Mac and PC.

[David Newman]

We have updated CineForm Neo Scene's bigger brothers, Neo HD and Neo 4K, to support the same GH1 fixes.

Thank you both for working this out. Isaac, have you had a chance to try this new version out yet?

[Isaac_Brody]

I tested the trial version and it properly removes pulldown. And you can tell the difference when you click "fix chroma" under processing. The footage looks visibly improved when bumped to 4:2:2, especially when it comes to banding.

cool. does the same go for 50i?

[David Newman]

With 50i, you can preserve 50i or convert to 25p using the base Neo Scene. With Neo HD you can convert to 50i/25p to 24p with audio pitch correction -- the pitch correction is a Windows option not yet ports to the Mac.

I just tried converting some mts files on my macbook pro running OS 10.5.6 and there's a few issues. First I tried the conversion with voltaic all good. When I convert the 720p "stormtroopers" file http://dl.getdropbox.com/u/1232715/00000.MTS to prores or cineform there's some dirty brown patches appearing in the black background that don't appear when I use voltaic. The whole picture also appears a little less sharp/clean. Also there's some performance issues, neo scene freezes and crashes and is sluggish. Also I couldn't get it to convert anything to 25p it was either 50p or 23.98p no matter what option I chose.

[David Newman]

That link is broken, I would like to pass the sample on, particular if you had conversion issues. Unlikely to be any color change as the conversion is a direct YUV to YUV transfer. Are you sure the other tool isn't truncating to black as YUV can hold more shadow and highlight details have stock RGB conversions. Converting 50p to 25p is not a current feature of Neo Scene, Neo HD can do that as a slow motion. Are you looking for slow motion, drop every second frame or blending frames to turn 50p to 25p?

It's hard to say because I haven't seen what the file looks like pre-conversion because it was just an mts file without the AVCHD folder so I couldn't do a log and transfer in FCP or open it in iMovie. I can see the brown patches when I convert in voltaic but they are barely noticeable whereas they are a lot more prominent using neo scene. here's where I got the file- http://www.dvxuser.com/V6/showpost.p...53&postcount=9 if you get in touch with QTI he might be able to pass the file on to you.

I wasn't looking for slow motion just a method to view these damn mts files on a mac. But I'm interested in using cineform instead of prores for editing and grading. I've heard some things about final cut pro 7 and quicktime native AVCHD editing which doesn't particularly excite me because I'm not about to blow the money on a machine fast enough to deal with AVCHD. But I'm hoping that color will have quicktime support so cineform would be a viable option.

I just installed the latest VLC update and was able to view the raw mts file and can confirm that neoscene is enhancing the brown patches in the black background. voltaic appears to produce a more accurate copy of the source file.

here's the "stormtrooper" mts source file http://www.megaupload.com/?d=SIMJXZEL

Your VLC test is still not conclusive, as there is no color transformation during the conversion -- there is no reason one file type would do something no others do. QuickTime is notorious for gamma shifts so you might be seeing something that.

[David Newman]

On the PC I tested VLC and Neo Scene and the color is indentical during playback and presentation. Weirdly when exporting a frame (snapshot) form VLC, it switched from 709 to 601 color, so the VLE export was wrong.

[squig]

no offense but testing it on a PC isn't conclusive either. I'll upload the file that I converted in neo scene for you to have a look at shortly.
