Star Wars GOUT in HD using super resolution algorithm (* unfinished project *)
Time

So you'd have to spline up to 720x540 before starting?

I'm just very intrigued by the potential of anamorphic 1080p to provide an alternative resolution that is Blu-Ray compliant and is able to squeeze higher quality into the same bitrates. I know a lot of projects use 720p as a way to incorporate lower quality footage in without standing out - I'm curious if 1440x1080p is capable of that as well, or if the seams show through. Considering the vast majority of fan projects are going to end up on SL 25gb BD-Rs, this resultion could be the sweet spot for providing quality. I'd imagine it might also reduce upscaling artifacts from projects attempting to scale to 1080p.

Hey  DrDre -

was wondering if you would try something for me.

Bluray Spec allows for anamorphic 1440x1080.

I'm curious how SR to 1440x1080, then Spline stretched to 1920x1080 looks compared to full blown SR to 1920x1080. (The spline stretch is simply meant to emulate the bluray player applying the anamorphic stretching)

Info wanted: General Encoding Question from Projects - Scripters opinions wanted.

Thank you for that, it helps a lot. I see your point on the credits - while it may seem useless to some, perhaps a simple script that checks the final size of a CRF encode, and discards it if over a certain size, starting over to encode again with a CRF value one lower (a smart script might even be able to judge how much larger the encode is than the desired size, and choose between 1, 2, or 3 lower depending on the overage).

Oddly, I see the potential in zones evening out quality in projects using different sources. Maybe CRF 16 for Upscaled HD footage, while bluray footage gets CRF 20+ to degrade the quality of the film through encoding the same way SD footage was originally degraded through encoding. I'd imagine this would work far better than any unsharp tool.

I’m searching for a way to encode a file for best possible constant quality, based on a specific size.

I was wondering if there was a way to tell an encoder to CRF up to the credits (specifiying a specific frame), at which point the credits are encoded using two pass to achieve an overall average bitrate, acknowledging the size of the CRF encoded portion as well.

You would set a minimum bitrate so that the credits weren’t totally botched. The encoder would look at the CRF portion, then see if the credits could be encoded at the minimum bitrate to reach the desired size. If not, the encoder would repeat the CRF encode at one value lower, and repeat the process. Otherwise, the two pass would be completed on the credits to allow for potentially better quality

All of you scripters… has this been done, or is there any way that you could look into a way to do this for mpeg2 and h.264?

Info Wanted: Best ROTJ preservations/reconstructions
Time

I think this thread would be more helpful if limited to RotJ only - even just listing preservations for SW and ESB is going to throw it off topic.

Q2s RotJ is a worthy consideration as well. 

RotP is in the works.

Poita is going to be working on RotJ first.

Team Blu is working towards an eventual blu upscale.

DrDre is rendering SW superresolution as we speak I believe, and. He has stated intentions to do ESB and RotJ as well
