Video2X

Pinned Video2X frame interpolation executable

Third_party

The binary lock owns the upstream release and SHA-256 integrity for the Linux x86_64 AppImage. It includes the Video2X CLI, FFmpeg libraries, ncnn, and RIFE models 4.6, 4.25, and 4.26. The release asset has no publisher-provided digest; the lock records the locally calculated download hash.

The host must provide an AVX2-capable CPU, a Vulkan loader, a compatible GPU driver, and access to its render device. No desktop session is required.

Run from the repository root with task-local extraction and cache directories:

mkdir -p out/video2x/tmp out/video2x/cache
export TMPDIR="$PWD/out/video2x/tmp"
export XDG_CACHE_HOME="$PWD/out/video2x/cache"
bazel run //third_party/com_github_k4yt3x_video2x:video2x -- \
  --appimage-extract-and-run --version
bazel run //third_party/com_github_k4yt3x_video2x:video2x -- \
  --appimage-extract-and-run --list-devices

The AppImage option extracts and runs without FUSE or installation. Select the device index reported by --list-devices. For example, this interpolates a caller-provided video fivefold using RIFE 4.25 and writes a lossless FFV1 video:

bazel run //third_party/com_github_k4yt3x_video2x:video2x -- \
  --appimage-extract-and-run \
  -i "$PWD/out/video2x/input.nut" -o "$PWD/out/video2x/interpolated.nut" \
  -p rife --rife-model rife-v4.25 -m 5 -t 100 -d 0 -a none \
  -c ffv1 --pix-fmt bgr0 --no-copy-streams --no-progress

Use absolute media paths. -t 100, also the default, disables scene-change skipping; lower thresholds can repeat frames across large changes. With multiplier m, this release emits 1 + m * (input_frames - 1) frames. To interpolate a closed loop, append its first frame to the input, then discard the final output endpoint. RIFE processes three color channels and does not preserve input transparency.

For repeated runs, the upstream --appimage-extract option avoids repeated extraction. Keep the extracted tree in task scratch. Set APPDIR to its absolute squashfs-root path and LD_LIBRARY_PATH to its usr/lib directory when invoking usr/bin/video2x directly.
