Director Philip John (who also helmed the fan-favorite “The Wedding” in Season 1) chose to shoot the battle with a gritty, handheld intimacy. No sweeping Braveheart drone shots here. Instead, we get close-ups of trembling hands loading muskets, the wet thud of a claymore into a redcoat’s haversack, and Claire performing field surgery in a muddy trench.
There is a moment in Outlander Season 2, Episode 10—titled "Prestonpans"—that captures the brutal arithmetic of 18th-century warfare. Claire Fraser, mud-splattered and desperate, watches as Highlanders charge across a foggy field near Edinburgh. The camera lingers on the clash of steel and the spray of peat water. It is visceral, chaotic, and deeply human. outlander s02e10 openh264
As the clansmen break into a sprint, the camera pans right. OpenH264’s motion estimation (the part that guesses where pixels will move) creates “ghosting”—afterimages trailing behind each running figure. Instead of 300 warriors, you see 300 blurry commas. Director Philip John (who also helmed the fan-favorite
But compromise is not what you want when Claire Fraser is sawing through a man’s leg without anesthetic. You want fidelity. You want the grime. The good news is that OpenH264 is already aging out. Newer codecs like AV1 (royalty-free and vastly more efficient) and H.266 (better at handling motion and fog) are slowly being adopted. Firefox and Chrome have begun prioritizing AV1 decode when hardware support exists. There is a moment in Outlander Season 2,
The bad news? Outlander was shot and mastered in 4K HDR (Dolby Vision for Seasons 2 and 3). That pristine master sits on a server somewhere, waiting. But until the entire chain—from streaming server to your laptop’s GPU—upgrades, episodes like “Prestonpans” will remain hostages to the lowest common denominator. We remember battles by their images. For the Jacobites, Prestonpans was a moment of impossible hope. For viewers in 2025, it has become an accidental stress test for video infrastructure. When a fan tweets that “the battle looked blocky,” they are not criticizing the director or the costume department. They are glimpsing the invisible war between artistry and algorithm.
Now if you’ll excuse me, I have a Blu-ray player to dig out of the closet. The redcoats aren’t the only ones who need a better defense. — A. J. MacKenzie is a freelance writer covering the intersection of digital technology and film history. Their favorite Outlander episode is “The Devil’s Mark” (S01E11), which looks terrible on OpenH264 but magnificent on VHS.
Next time you watch Jamie Fraser raise his sword in the fog, take a moment to thank—or curse—the open-source codec that delivers him to your screen. And if his face dissolves into a checkerboard of pixels just as he cries “ Tulach Ard! ,” know that you are witnessing not a glitch, but a very modern kind of historical reenactment: the struggle of a 21st-century invention to honor an 18th-century charge.
