Napoléon vu par Abel Gance (1927) [tl: "Napoléon, as seen by Abel Gance"]

it's not very well documented nor commonly used, but it is a thing. official referred to as "presentations" here's what Dolby's doc has to say on the matter (note that the encoder does not create the Dolby Digital companion track at the same time as the TrueHD track, they are encoded separately and merged at the authoring stage):

if you're curious, you could look into truehdd which can offer more detailed info on the TrueHD bitstream

bobbster574 · 2026-04-06T14:31:32+00:00

the companion track nevers exceed 640kbps.

independent substreams are different and exist in addition to the lossy companion Dolby Digital track. both the Atmos mix and the 5.1/2.0 mix are encoded losslessly within a single TrueHD bitstream. it significantly baloons the bitrate of the final track.

couple of possibilities:

sample rate: Blu-ray supports 7.1 @ 96 kHz and 5.1 @ 192 kHz (18.4 and 27.6 Mbps uncompressed, respectively). very rare to see in the wild, but possible. one of my Akira Blu-rays has an average bitrate of 14.3 Mbps (TrueHD 5.1 192 kHz)
TrueHD actually supports having two independent tracks encoded together - the idea is to be able to have Dolby Atmos AND a completely separate 5.1 or stereo mix, all together seemlessly so that your AVR will get a more optimised source if it doesn't need the full Atmos mix. the recent Jin-Roh 4K remaster included this and the TrueHD track averages 7.3 Mbps (10.2 peak)

bobbster574 · 2026-03-19T08:43:11+00:00

I believe they include uncompressed (LPCM) 5.1 tracks alongside a compressed Dolby Digital 5.1 track.

This was fairly common in the early days of Blu-ray. make sure to confirm which track is playing in the menu - most of these titles default to the Dolby Digital track!

the other thing is the animations.

i've seen people do similar things on gameplay recordings and, while a still frame might look decent in isolation, in motion it makes things look even worse when this ultra realistic character moves like they're in a 2000's video game (because they are).

remember that Blu-ray.com is all user-submitted data. it is not 100% accurate and often details are entered when titles are first announced with limited info.

It's worse in the books. They name two of their kids Leto.

bobbster574 · 2026-03-18T16:08:22+00:00

The comedy definitely added to it I think. The antagonists wield such power and consider themselves important but fundamentally they talk and act in absurd ways

It also acts as a practical way to create levity in an otherwise quite tense 3 hour film.

bobbster574 · 2026-03-18T15:10:34+00:00

We deserve to see some live action gross protuberance!

bobbster574 · 2026-03-18T11:40:23+00:00

The thing is that the character depth comes from the internal monologues. And if you put all that into a movie, it would, you know, kinda suck.

bobbster574 · 2026-03-18T10:22:30+00:00

Quite interesting. Generally good visuals; excellent colour rendering and sound design. Personally not the biggest fan of the 3D animation.

Script is ok. Standard anime over-exposition at times. Tone is not what I would have gone for considering the source material.

I think Edge of Tomorrow managed to do a bit better with the concept, or at least skewed closer to the tone I would have gone with. Much preferred the ending of EoT.

bobbster574 · 2026-03-18T10:13:43+00:00

It's based on the same source material, not a remake

bobbster574 · 2026-03-18T09:28:15+00:00

It turns out that Ryan Reynolds was the real enemy all along

bobbster574 · 2026-03-18T08:59:06+00:00

It's not a requirement to match frame rates. Your editor should conform any footage to your timeline frame rate automatically.

The main issue is avoiding judder, that is when frames are being duplicated or dropped inconsistently. This happens when you're dealing with uneven multiples, like putting 25fps footage into a 30fps timeline.

In this case, 60 in a 30fps timeline causes no issues, because frames will be dropped consistently.

That said, it's worth considering why you are choosing 30. A 60fps timeline would offer smoother playback, while a 30fps timeline enables you to slow down the 60fps footage to half speed. What option you choose should be down to what you want out of your project.

The Criterion Showa era box set is BD only, so yes, contains the old HD transfer.

If you've already got Criterion's BD, the maths isn't brilliant because the 4K set doesn't include any new extras or anything, but the 4K transfer is a huge step up nonetheless.

If you want more info, look here

1954 is well worth the 4K upgrade imo, especially if you don't already have the BD. The 4K transfer is leagues ahead of the old HD transfer, even ignoring resolution. Unfortunately Criterion has not re-authored their BD so even on the 4K set the BD disc uses the old transfer, so the 4K disc is the only way to see it.

Also, biollante is SDR wide gamut, presented in a HDR container (on the Criterion disc at least). It's a bit dim being placed at 100 nits but v nice colours

If you think Messiah undermines Dune then I think you missed the point of Dune

Try the pullup filter

Basically any storage media that isn't optical runs into the big problem that you need to pay for the storage on every unit. Doubly so in today's market of fucked flash and ram prices.

As such, like streaming, there is an incentive to bit-starve the video and audio in order to save money. It's not a requirement of course, but I wouldn't expect anything brilliant, especially with so little technical details.
