LogGate Frame: Video Upscaler
Local Upscale, No Subscription
$19.99
The only App Store upscaler that keeps Apple Log 2 intact end-to-end. Native MetalFX on Mac, iPhone & iPad. No subscription. Built for editors who shoot in log.
Most upscalers re-encode your footage and bake Apple Log into Rec.709. LogGate Frame doesn't. It runs Apple's native MetalFX spatial scaler and passes every color tag through untouched — Apple Log 2, HDR10 PQ, and HLG all round-trip at higher resolution exactly as they went in.
Apple Log 2 metadata preservation through a batch upscale isn't available in any other App Store app. Now on Mac, iPhone, and iPad — one purchase covers all three. No subscription.
WHAT IT DOES
• 1.5×, 2×, 3×, or 4× upscale via Apple's MTLFXSpatialScaler
• Batch — drop a folder of clips, get a folder of upscales in minutes
• Apple Log / Log 2 round-trip with full LogTransferFunction preservation
• HDR10 (BT.2020 PQ) and HLG round-trip without re-tagging
• Audio passthrough — PCM stays PCM, AAC stays AAC, zero re-encode
• Cloud-aware: detects iCloud Drive, LucidLink, and SMB sources, copies to local SSD before processing, bulk-moves output to the destination
• Disk space preflight catches "not enough room" before GPU work begins
• Per-batch markdown + CSV report with phase-by-phase performance data
• Universal — runs natively on Mac, iPhone 15 Pro and later, and M-series iPad; import from Files or Photos and share anywhere
CODEC COVERAGE
Apple ProRes 422 / 422 HQ / 4444 / ProRes RAW, HEVC 8-bit / 10-bit / HDR10 / HLG, H.264 up to 4K, 60 fps and 120 fps high-frame-rate. Apple Log 2 from iPhone 15 Pro and later and from Atomos external recorders is tested and verified. H.264 above 4K is automatically written as HEVC (H.264 spec caps at 4K).
PERFORMANCE
Real numbers on real hardware:
• M4 Max: 117.5 fps wall on a 4K Apple Log 10-bit clip at 2× upscale
• M4 Max: 104-clip Atomos batch (72,000+ frames) in 43 minutes
• M4 base (MacBook Air): 53.8 fps on 1080p → 4K — twice real-time at a 25 fps source; 85.1 fps average across a 19-clip mixed-resolution batch
Concurrent batch workers scale by chip class: 1 on M-base, 2 on M Pro / Max / Ultra. On Max-tier chips with local SSD storage, the GPU is the only thing in the way.
Output tops out at 8K-class resolution — the largest the spatial scaler and ProRes encoder sustain reliably. Higher scales are offered automatically only when the source is small enough to stay within that ceiling.
WHAT IT DELIBERATELY DOESN'T DO
LogGate Frame is single-purpose. No format conversion. No color management. No LUT application. No AI upscale, no generative fill, no face enhancement — just Apple's MetalFX spatial scaler running natively on Apple Silicon GPU cores. No annual subscription. No AI model license. No cloud processing.
For Log → Rec.709 transforms, smart cropping, or social-media variant exports, see the companion app LogGate Pro. Shoot Apple Log → upscale with Frame → grade with Pro.
WHO IT'S FOR
Pro video editors shooting Apple Log on iPhone or Atomos who need to upscale 1080p / 4K footage for 4K / 8K delivery without losing their log master. Color graders who can't afford colorspace contamination before opening a node. Drone, GoPro, and mirrorless shooters with mixed-codec project bins who need clean 4K / 8K deliverables.
SYSTEM REQUIREMENTS
Universal app — one purchase covers Mac, iPhone, and iPad:
• Apple Silicon Mac (M1 or later), macOS 14.2 Sonoma or later. Intel Macs are not supported.
• iPhone 15 Pro or later (A17 Pro or newer), iOS 18 or later.
• iPad with M1 or later, iPadOS 18 or later.
MetalFX's spatial scaler requires this class of GPU; older devices aren't supported. One-time purchase. No subscription.
LogGate Frame v1.1 brings the upscaler to iPhone and iPad, adds still-image upscaling, and fixes ProRes RAW.
NEW
• iPhone & iPad.
• Image upscaling. Drop in JPEG, PNG, HEIC, TIFF, or DNG stills and upscale them through the same MetalFX scaler, with JPEG / PNG / HEIC output.
• ProRes RAW, fixed. ProRes RAW (aprn / aprh) now decodes and upscales correctly to ProRes 422 HQ. Earlier builds could finish these with an empty file.
