October Of Horror 2024

Posted by Trixter on October 28, 2024

(Edit 2025: I have been informed that “letterboxd” is a better outlet for this sort of thing, so I joined letterboxd and will put future reviews there.

I use every October as an excuse to binge horror movies. I’ve tried reviewing them at length on this blog in the past, but that turned out to be a colossal waste of time (I spent at least 15 minutes writing each review, about 4 hours total, and each post got single-digit views). But I still feel sharing the experience is useful in some way, so I’ll write the full list up with a small snippet of whether or not I recommend it and why.

I decided to try something different this year: Sort all of the unwatched horror movies I have on my local media server from WORST to BEST, according to audience rating. The idea was that, as I move from movie to movie, they would keep getting better and better :-D I have to say, the experiment worked! They started out utterly ridiculous, and slowly got better and better, with the occasional surprise (very bad, or very good) along the way. A few times, I couldn’t take it any more and watched a much better movie instead of following the rules I had set up for myself, but for the most part I stuck to the experiment and was pleased by it.

Here’s the list, in watched order:

  1. The Phantom Eye (1999): Roger Corman cheese. Recommended.
  2. The Prophecy (1995): Angels fighting angels. Christopher Walken as an angel! Recommended.
  3. Dracula (1931): A classic. First half much better than second half. Recommended.
  4. The Prophecy II (1998): A sequel, worth seeing for more Walken. Barely recommended.
  5. The Prophecy 3: The Ascent (2000): Weak and not enough Walken. Skip.
  6. The Prophecy: Uprising (2005): Low budget side-quel. Hallmark of low budgets is way too much dialog and not enough action or locations. Skip.
  7. The Prophecy: Forsaken (2005): Sequel to low budget side-quel. Forgettable. Skip.
  8. The Clonus Horror (1979): First half better than second half but worth sticking it out. Recommended.
  9. The Hand (1981): This was WAY better than the ratings suggested. Michael Caine’s severed hand starts murdering people who anger him. Highly recommended.
  10. Devil Doll (1964): Twilight zone did this way better (twice). Skip.
  11. New Terminal Hotel (2010): The return of Stephen Geoffreys to mainstream acting. He’s good, everyone else is not. Skip.
  12. Halloween III: Season of the Witch (1982): Can’t believe I hadn’t seen this before 2024! This is totally not a Halloween movie, and it’s super bananas at times, but I was never bored. Commentary track with Tom Atkins is just as entertaining as the film. Highly recommended.
  13. Uncle Sam (1996): Desert Storm zombie comes back as Uncle Sam to wreak patriotism on a small town. Recommended (barely).
  14. How to Make a Monster (2001): Computer program comes to life and kills people. Obligatory Julie Strain appearance. Computer-speak is difficult to cringe through, but there were some cute and clever moments. Recommended if you like “OMG computers world wide web first person shooter” cheese from the early 2000s.
  15. Contamination (1980): Italian rip-off of Alien that was so terrible I was yelling at the screen. Avoid at all costs.
  16. He Knows You’re Alone (1980): Serial killer hunts down brides-to-be. Tom Hanks’ first movie where he has no impact on the story at all. Forgettable.
  17. Frankenstein (1931): A classic. Worth seeing.
  18. The Initiation (1984): Daphne Zuniga’s first film. One of two horror films I watched this month set in a mall. Skip.
  19. The Video Dead (1987): An offbeat zombie horror film. One of two horror films I watched this month where zombies invade our world through a television. It’s not really worth seeing, despite two funny uses of an iron.
  20. Frankenstein Unbound (1990): Roger Corman’s reimagining of Frankenstein. Fantastic cast, surprisingly good props for the budget (a Corman tradition), but ultimately not worth seeing. It’s just not enjoyable to watch.
  21. Hellbound (1994): Chuck Norris swears and kicks demon butt. Movie, however, does not kick butt. Skip.
  22. The Puppet Masters (1994): The “28 weeks later” of Invasion of the Body Snatchers. Recommended.
  23. Prom Night (1980): Rumor has it that Jamie Lee Curtis agreed to star, at a low salary, if she were permitted to dance. And disco dance she does. Not enough to save the film though. Skip.
  24. Strange Invaders (1983): A nearly perfect homage to 1950’s communist-scare alien movies. If you haven’t seen any 1950’s sci-fi then you won’t be in on the joke and probably won’t like it. Recommended (barely).
  25. The Boogey Man (1980): Ineptly handled horror slasher. Skip.
  26. The Final Destination (2009): Not as good as the first Final Destination film, but still very enjoyable and has fun with the kills. Recommended.
  27. The Wolf Man (1941): Another classic, and worth seeing — but there’s a lot of 1940s-isms that don’t resonate very well today, like discrimination and sexism. Lon Chaney Jr. is better in makeup than not. Tough to recommend.
  28. Christmas Evil (1980): A fascinating film that is more drama, exploitation, and thriller than horror. A statement against apathy and commercialism. Recommended, but only barely.
  29. Evilspeak (1981): Clint Howard conjures up the demon form of Richard Moll using an Apple II computer! It’s a terrible film, but come on, conjuring demons with an Apple II. Reluctantly recommended.
  30. Mutant (1984): Inept zombie movie with inept shambling zombies that are created by inept chemicals from an inept evil company. Did I mention it was inept? Skip (unless you like seeing Wings Hauser ad-lib half his lines)
  31. Friday the 13th: The New Blood (1988): Jason against a girl with telekinesis. Does not live up to the promise of Jason-against-telekinesis, unfortunately. Skip.
  32. Mimic (1997): Guillermo del Toro’s worst film is still worth watching. Director’s Cut is supposed to be better than the theatrical cut I watched. Recommended.
  33. ABCs of Death 2 (2014): I loved this! 26 different short vingettes from 26 different directors. Recommended.
  34. Ben (1972): A lonely boy befriends a smart leader rat of a smart rat swarm. Sequel to Willard. Super slow with no real payoffs. Hated them both. Skip.
  35. Chopping Mall (1986): Robots kill teens hiding in a mall after dark. Second of two horror films I watched this month set in a mall. Unlike the other one, this one is very silly, but it knows it and has a ton of fun with the premise. Recommended.
  36. Demons 2 (1986): Italian film that tries to rip off so many movies simultaneously I lost count of how many. Second of two horror films I watched this month where zombies invade our world through a television. Dreadful film that even the good makeup/prosthetics can’t rescue. Skip.
  37. The Children (1980): Deadly children! Low budget but manages to stay interesting throughout. Recommended.
  38. A Cold Night’s Death (1973): Two-person movie where Robert Culp and Eli Wallach try to figure out what killed everybody at a remote arctic research station. Originally a made-for-TV movie, rises above that and was one of the hidden gems of this month’s horror movie experience. Highly recommended.
  39. Mom and Dad (2017): Mass hysteria causes parents to murder their children. Nicolas Cage and Selma Blair do their best with the material, but the movie loses confidence in its own premise. Can’t really recommend it.
  40. Return of the Living Dead III (1993): One of my favorite cult classics — I have seen this many times before but try to watch it once a decade anyway. Has a few unique and cynical twists on the living dead zombie premise. If you liked the first RotLD from 1985, you’ll like this one. (Skip the second RotLD.)
  41. The Night Flier (1997): Miguel Ferrer investigates a serial killer who travels by plane. Takes a while to get going but ultimately worth it. Recommended.
  42. Popcorn (1991): Horror comedy mystery. Resisting urge to call it cheesy. “Black Comedy For Dummies”. Barely recommended.
  43. Dead Hooker in a Trunk (2009): Student project made for $2500. Great student project, disappointing movie. Skip.
  44. The Eye (2008): I see dead people, but not as good as Sixth Sense. What could have been a good premise is wasted on Jessica Alba’s limited acting ability. Skip.
  45. Poltergeist (1982): The last time I saw this was in August 1982, when my brother and I snuck into the theater to watch it after having watched Tron. Came across the 4k version and decided to revisit it. Fantastic movie where many aspects of it still hold up. Highly recommended.
  46. House of Wax (2005): Starts slow but methodically gets better and better as the movie goes along. Paris Hilton, surprisingly, can actually act. Some very unexpected practical effects. Recommended.
  47. Sixteen Tongues (1999): Cinema verité shot on analog video DV cams. True cyberpunk, which is dystopian and depressing. Extremely low budget (the “future” is littered with 16-bit ISA cards and classic Macs), takes place in a single location. Script is so good that it exceeds the acting capability of the actors, sadly. Not Rated (which means practically X-rated). I’m glad I watched it, as I’m a fan of performance art, but I can’t really recommend it as it will disgust most people.
  48. The Keep (1983): Michael Mann’s only non-crime-thriller movie. Was clearly a much longer film with better narrative pacing before it was cut in half by producers. Cool practical effects. Recommended.
  49. Hell Night (1981): College hazing takes a wrong turn after locking people in a house that is already inhabited by a psycho. Takes forever to get going and almost never gets there. Skip.
  50. The Sentinel (1977): A woman has psychic flashbacks after moving into a strange apartment complex. Despite many recognizable stars, has a weak payoff. Used people with actual physical deformities as scary people, which is not really acceptable today. Skip.
  51. The Thing (2011): This is the prequel to The Thing (1982), which itself is a remake of The Thing From Another World (1951). All of them are recommended and each bring something to the table, but Carpenter’s The Thing (1982) is clearly the best and should be watched BEFORE watching this prequel, as the prequel will permanently spoil the 1982 film. Recommended.

51 movies — a new record for me. There are still days left in October, but I think I’ll stop there.

Hope this helped someone!

Panasonic Lumix G9 Mark II Overheating Test Results (and workarounds)

Posted by Trixter on October 17, 2024

Amendments after additional tests:

With a dummy battery, the screen flipped out, no active cooling, and a normal ambient room temperature, a 4k60 4:2:0 10-bit recording overheated the camera sometime after 3 hours.

The same setup WITH Ulanzi active cooling, a 4k60 4:2:0 10-bit recording ran indefinitely with no heat warning.

TL;DR

I spent a week performing a lot of G9 II overheating tests, and am presenting the results here. The quick summary: There are some things you can do to prevent the G9 II from overheating, but they have their own pros and cons. Ultimately, if you want to record tons of video without any overheating, you should not buy a G9 II, and should instead spend the extra cash on a GH7.

Full test parameters and results are below. Before continuing, a disclaimer: A few links in this blog post are affiliate links to the exact products I actually purchased and tested with. Clicking on these links don’t cost you any extra money, but may earn me a small commission.

Background

I shoot primarily long-form video: Product photography, talking heads, and events. I am invested in the micro four thirds (M43) lens system, and bought a Panasonic Lumix G9 Mark II as soon as I was able to afford one, because I really wanted the first Panasonic M43 camera with phase-detect autofocus. It works great, and the autofocus is finally fantastic — however, it overheats during longer video shoots, shutting down video recording functions for 13 minutes to recover.

What’s worse, I bought it at the worst possible time: 35 days before they announced the Panasonic Lumix GH7, which doesn’t overheat. 5 days past the return policy, it was too late to return my G9 II for a refund. If I try to sell it on ebay, I can expect a $600 loss. So I guess I’m stuck with it.

Trying to make the best of a bad situation, I decided to see what the overheating limits are, so I let the video recording run as long as it could in different resolutions, framerates, colorspaces, and codecs. The results are below, and I hope they are helpful to someone.

Test Setup

Almost all my shots are locked down on a tripod, so that’s what I used for these tests. I have been shooting 4k exclusively since 2016, so I didn’t bother with smaller resolutions. I didn’t test any ALL-I modes because I haven’t used them since Panasonic added h.265 to their cameras (and ProRes to the G9 II). I also didn’t test true DCI 4K (4096×2160) modes, as I felt UHD 4K (3840×2160) was the more common use case.

Here are the test parameters I adhered to:

  • Indoors at room temperature (roughly 70F/21C)
  • On tripod
  • Screen was flipped OUT. (Very important!! This exposes the back of the camera to release more heat!)
  • Used “dummy” battery connected to mains/wall power
  • Heat management was set to “high”
  • Recorded to 2 x 128G v90 SD cards mirrored (128G total storage). Cards were reformatted between each test.
  • 1/60 shutter (to match room lighting frequency) for all 60p/30p/24p modes
  • Waited until back of camera was cool to the touch before starting a new test
  • All recording formats were h.265 (LongGOP). Colorspace was 4:2:0, as I didn’t notice any significant heat differences between 4:2:0 and 4:2:2 during initial testing.
  • Times reported are the lengths of the resulting footage files, truncated to the nearest minute
  • All recording modes were the full readout of the sensor, with the exception of the 4.4k modes which are a 1:1 pixel crop
  • All tests were performed three times, and the median value chosen as the result

5.8K (4:3)24pOK1h27mFull sensor readout / “open gate”
5.8K (4:3)30pOK1h27mFull sensor readout / “open gate”

I was very surprised the 5.7k 17:9 (5728×3024) 30p mode overheated much faster than the 5.8k 4:3 (5760×4320) 30p open gate mode, as the full-res open gate mode processes more information per frame. I have neither explanation nor theories for this behavior.

Do larger/slower SD cards help with overheating?

To see if shooting long-form events were possible, or if slower cards caused more (or less) issues, I used larger+slower SD cards to see how far I could push the camera. I saw no significant differences in overheating performance doing this. Modes that overheated still overheated at roughly the same length. Modes that previously worked continued to work.

For example, recording to UHD 4K 60p filled a 512G V30 SD card with 5+ hours of video. As in the previous test, this also flashed a heat warning around the 50 minute mark, but it kept going and filled up the card.

Does an ULANZI Camera Cooling Fan help with the overheating?

Yes. Mini-review:

The ULANZI Camera Cooling Fan is a $40 battery-powered add-on fan with two speeds and a temperature display that attaches to most mirrorless cameras designed with a flip-out screen. I bought one and connected it to continuous power (only fair, since my camera was on dummy battery continuous power as well), set it to high speed, and re-tested the modes that previously shut off due to overheating. Results:

ResolutionFramerateBehavior with fanOld limitNew limit with fan
UHD 4K120poverheated23m23m
4.4K (4:3)60pOK41m58m
5.7K (17:9)30pOK45m1h27m
5.7K (17:9)60pOK33m58m

So, the Ulanzi fan definitely helped extend the recording times in most modes that had overheat shutoff issues.

That said, there are some caveats to using it:

  • Mine did not stay connected to the G9 II very well; it kept sliding down, then flying off at great velocity because of the spring-loaded nature of how it attaches to the back of the camera. I added four small adhesive rubber “bumps” to all four corners to permanently solve this issue.
  • The fan is not silent, and raises the noise floor picked up by the camera’s microphones to -30dB. (That said, nobody uses the built-in camera audio for anything serious.)

Does writing ProRes to an SSD help with overheating?

Not really. The only video mode that overheated that also had a ProRes equivalent was 5.7K (17:9) 30p, so “prores as a way to generate less heat” is only useful in one recording scenario. Not only is this a very narrow limited scenario, it still overheated. Writing to an SSD led to a max recording time of 64m (prores) vs. 51m (h.265).

For SSD testing, I used a cheap but fast M.2 USB-C enclosure with an older 256G M.2 NVME card I had lying around.

Does using an external recording monitor help with overheating?

Yes. I used an Atomos Ninja (newer version, not the Ninja V) as the monitor + recorder for the G9 II, as I had purchased it earlier in the year for an unrelated project. In all recording scenarios, I was surprised to see the G9 II heat up, even though it wasn’t recording! But despite that, it never fully overheated and stopped, even when displaying the flashing heat warning.

The highest RAW resolution and framerate I could achieve with my Ninja (the Ninja Ultra can go higher) was 5.7K 30p. Where the native camera overheats and shuts off at 45m using that resolution and framerate, using the Ninja resulted in no overheating and filled a 2TB SSD with over 3.5 hours of ProRes RAW footage.

Recommendations and Conclusions

While I’m stuck with my G9 II, I was happy to see that some demanding modes such as UHD 4K 60p and 5.8K 30p can record nearly indefinitely at normal room temperature. For other demanding modes that overheat, at least I now know what they are and can plan accordingly.

Please keep in mind that these numbers were the result of optimal indoor shooting conditions. If you’re shooting outdoors with direct sunlight hitting the camera, or you shoot with the flip-out screen in the closed position against the back of the camera, you can probably expect 1/3rd (or less!) of these runtimes, and should buy a GH7 instead.
