This DVD is a part of Bohemia Motion Pictures' "Klenoty českého filmu" ("The Jewels of Czech Cinema") collection - conceived to take advantage of the availability of new high-definition masters created primarily for HDTV broadcast.
     Broadcast-shmroadcast, THE question everyone & their dog are dying to know the answer to is: "Does the remastered version finally blow the 2005 non-anamorphic Bonton DVD, which - however strange it may sound - is still the reference point here, out of the water?" And I can't really say it does, but at least it doesn't look worse AND is anamorphic, meaning that if your player's image processing circuitry is not too sophisticated, the native 16:9 picture will most probably look better on your [wide]screen than a zoomed-in letterboxed one...

Update: I realize the different frame sizes in our gallery make comparison difficult, so here's one more example - the BMP capture is at its native resolution of 1024×576 (sans black bars); the Bonton one has been re-formatted to match (the AR was not kept):

This is a recording from ČT2 HD's digital satellite broadcast. Its purpose here is to provide a kind of reference for the Blu-ray release reviewed below.

Note: This is an older HD master - the one Bohemia Motion Pictures used for their 2016 DVD release (just compare the 2 versions in the gallery). I'm guessing here [in an educated way ;-)], but Second Run's 2017 Blu-ray most probably came from the same source (possibly with some additional cleanup).

Special thanks to LeoH, a regular @ the Zóna discussion board, for making this comparison possible! (c:

As expected, Second Run's Blu-ray uses the same *unrestored* master the Czech TV aired a while ago, just with a gazillion times better encode.

A mixed bag, this... The new 4K resto that premiered at this year's [2019] Karlovy Vary International Film Festival is great, but - unlike Bohemia Motion Pictures' past Blu-rays of "Nick Carter in Prague" or "Three Wishes for Cinderella" - there's not a single bit, let alone a byte, of supplemental material here, which "The Cremator" would've deserved much more than either of the aforementioned titles.
