Android video processing utility
Split long recordings, keep one frame out of many, build dynamic frame averages, or generate exact statistic snapshots without sending video to the cloud.
VideoOps is a phone-first Android utility for chunked splitting, frame downsampling, dynamic frame averaging, and whole-video statistic snapshots, with all processing kept local on-device.

Both downsample and averaging keep the same configurable frame-window range.
Downsample, dynamic averaging, and statistic snapshot increment numeric suffixes until a free name is found.
Split can preserve audio when the input includes it. Downsample and dynamic averaging discard audio.
Support
If VideoOps is useful in your workflow, support broader device validation and export hardening.
Support helps fund Android device coverage, codec compatibility checks, and the work needed to keep local video processing reliable across releases.
How it works
4 focused workflows from one landing page.
Split videos
The app starts on a single landing page that switches between split, downsample, dynamic averaging, and statistic snapshot workflows.
Keep source quality and prevent accidental overwrite by stopping if any target chunk name already exists.
Downsample videos
Split can preserve audio when the input includes it. Downsample and dynamic averaging discard audio.
Discard audio from the downsampled output.
Dynamic averaging
Every workflow defaults to the source base name and adds a collision-safe numeric suffix instead of overwriting prior exports.
Support configurable frame windows from 2 to 2048.
Statistic snapshot
Build one PNG image from the whole video using mean, std, variance, min, max, range, median, mode, first quartile, third quartile, interquartile range, luminance mean, or luminance std.
Optional approximate mode computes the statistic frame from a random subset of extracted frames for faster turnaround when exact precision is not required.
Features
Everything VideoOps handles, workflow by workflow.
Workflow 1
Split videos
The app starts on a single landing page that switches between split, downsample, dynamic averaging, and statistic snapshot workflows.
- Select a video file and split it into configurable chunk durations.
- Keep source quality and prevent accidental overwrite by stopping if any target chunk name already exists.
- Optionally preserve source audio when the input includes audio tracks.
- Use overlap mode so each next chunk starts ov seconds before the previous chunk ends, where ov is greater than 0 and smaller than chunk length.
Workflow 2
Downsample videos
Split can preserve audio when the input includes it. Downsample and dynamic averaging discard audio.
- Keep one frame out of every configurable n frames, with n ranging from 2 to 2048.
- Discard audio from the downsampled output.
- Default the output base name to the input file name and append a collision-safe down_{n}_%03d suffix.
Workflow 3
Dynamic averaging
Every workflow defaults to the source base name and adds a collision-safe numeric suffix instead of overwriting prior exports.
- Build output frames by averaging RGB values across a sliding window of n consecutive frames.
- Support configurable frame windows from 2 to 2048.
- Discard audio and write collision-safe avg_{n}_%03d outputs.
Workflow 4
Statistic snapshot
- Build one PNG image from the whole video using mean, std, variance, min, max, range, median, mode, first quartile, third quartile, interquartile range, luminance mean, or luminance std.
- Optional approximate mode computes the statistic frame from a random subset of extracted frames for faster turnaround when exact precision is not required.
- An all-statistics batch toggle creates every supported statistic in one run after a single frame extraction pass.
- In all-statistics mode, each PNG is written to DCIM/videoops as soon as that statistic completes instead of waiting for the entire batch.
- For long inputs, statistic extraction automatically keeps every x frame and limits extracted frames to 4500 to reduce temporary storage usage.
- Compute each output pixel from the same pixel and channel across all frames in the source video.
- Reuse extracted frames for range and quartile-derived statistics, and visualize variance with an 8-bit normalization.
- Show extracted-frame progress in a dedicated progress bar during long statistic snapshot runs when the source video reports a frame count.
- If the app is closed after frame extraction finishes, the next launch can resume unfinished statistic generation from the last incomplete output while cached frames remain available.
- Continue with available extracted frames when a small subset is missing, and fail with a clear error when too many frames are unavailable.
- Save collision-safe stat_{name}_%03d PNG outputs under DCIM/videoops.
Quality and reliability
Release confidence is built into the workflow.
This same release hardening mindset carries through local checks and device-level export validation.
FAQ
Common questions about VideoOps.
Where do outputs go?
All generated files are stored in an app-specific folder under DCIM/videoops.
How are duplicate names handled?
Downsample, dynamic averaging, and statistic snapshot increment numeric suffixes until a free name is found. Split checks the full output set first and stops with an error if any target name already exists.
What happens to audio?
Split can preserve audio when the input includes it. Downsample and dynamic averaging discard audio.
