About Batch and Interactive Editor

How to use Interactive Editor

  1. Open Batch originals as a sequence, or choose Edit in editor to also carry your current settings.
  2. Select a clip to trim, split, slip, set speed, frame the picture or mix its sound. Add tracks, titles, images and music; Undo keeps changes reversible.
  3. Export MP4/WebM or explicitly save a project to keep originals and tracks editable. A recipe repeats the arrangement in either workflow mode.

Mode switching resumes independent sessions. Editor output uses one frame size up to a 1,920 px longest side / 30 fps, and re-encodes frames. Batch retains its existing fast operations and limits. Trim/Crop Batch still edit one video at a time.

Editor limits: 20 sources / 1 GB total, videos up to 500 MB and 15 minutes each, audio up to 50 MB / 15 minutes, 30-minute output. Saved projects include originals and their metadata. Recipes contain only settings and generic source slots; nothing is saved automatically.

How it works

How to rotate a video in Batch

  1. Add up to 20 MP4, MOV, MKV or WebM videos, 500 MB each.
  2. Choose 90° right, 90° left or 180°, and tick Mirror or Flip if needed. The previews turn as you choose.
  3. Click Rotate video, play each result and download one video or a ZIP.

Compare orientation metadata with rewritten frames

Add the 12-second practice MP4. Choose 90° right, leave Mirror and Flip off, and keep Rewrite every frame off under Compatibility. Click Rotate video.

The 12-second result should display the scene sideways in a 360 × 640 orientation, with the same tone. This deliberate turn is a test: on a real sideways recording, choose the turn that makes it upright.

If your destination ignores the orientation flag, export again with Rewrite every frame on and compare it there. Rewriting and mirroring encode new frames and can change quality.

Frequently asked questions

Useful details

5 answers
Can I arrange clips on a timeline?

Yes. Interactive Editor offers tracks, trim/split/slip, per-clip speed, framing, titles and audio mixing. Edit in editor carries Batch originals and settings. Each mode retains its own session.

Is rotating lossless?

A 90° or 180° turn can be lossless when its codec fits MP4 and no step requires new frames. Mirroring and flipping always rewrite the frames, because many players ignore a mirror flag. When the picture can be copied into MP4 and no frame-changing step is added, only its orientation is updated.

How do I fix a mirrored selfie video?

Tick Mirror left to right, with no turn if the video is already upright.

Why does the rotated video look sideways in one app?

Some older players ignore the orientation flag. Rotate again with Rewrite every frame turned on under Compatibility.

Is my video uploaded?

No. Rotation happens in your browser on this device.
