In Pro Tools, a feet frame mismatch with the frame grid means the video playback rectangle (the feet frame) does not align with the current timecode or grid position, often showing a offset during video playback. This guide explains common causes, how to confirm the issue, and evergreen workflows to realign feet frame to the frame grid so your edits and deliveries stay accurate.
What Is the Feet Frame and Frame Grid in Pro Tools
The feet frame refers to the visible rectangle in the Edit or Mix window that indicates the active video frame during playback. The frame grid refers to the timebase ruler and underlying grid that represents your session’s timecode or sample grid. When these do not line up, you see the playhead at a different video frame than where the feet frame appears, which can cause confusion in edit decisions and lead to export mismatches.
Typical Causes of Feet Frame Misalignment
- Timecode mismatch between media and session.
- Stem or video track latency from plugins or delay compensation.
- Offline or relinked media with incorrect frame rates.
- Playback engine settings or video drivers introducing delay.
- Misconfigured video track output or custom offset automation.
Confirm the Issue with Reference Checks
Before correcting, verify that the feet frame is truly misaligned and that the issue is not a display refresh or zoom factor. Compare the timecode read by the playhead to the timecode shown in the feet frame overlay or in the Source Monitor metadata.
Check Playhead Timecode
Look at the primary timecode display in your Pro Tools window. Note the exact timecode and compare it to the timecode shown in the video window overlay or the clip’s header metadata.
Inspect Clip and Track Latency
Check for delay compensation indicators on tracks, and review clip delays or Nudge values in the Clip List. Even small plugin latency can shift the visible feet frame without moving the playhead.
Evergreen Workflows to Realign Feet Frame to Frame Grid
Follow these structured steps whenever feet frame and frame grid are out of sync. They are designed for long-term reliability and to prevent drift in future sessions.
- Match session timecode rate to media timecode rate.
- Disable delay compensation temporarily to see true offset.
- Use the Video > Sync to Timecode command when available.
- Nudge or trim clips in small increments while watching the feet frame.
- Re-enable compensation and verify overall mix alignment.
Sync to Timecode and Update Playback Engine
If your media includes timecode, use Pro Tools tools to snap the session to the timecode master. Then confirm your Playback Engine settings match the video’s frame rate, and update video drivers if you notice rendering lag.
Use Ruler and Grid Snapping for Frame-Accurate Edits
Turn on grid snapping set to your frame rate division (e.g., one grid for each frame in 23.976 or 29.97). This keeps edits aligned with the intended video frames and reduces accidental drift.
Factual Details: Common Frame Rates and Offset Thresholds
| Attribute | Verified Detail | Source Type |
|---|---|---|
| Common Frame Rates | 23.976 fps, 24 fps, 25 fps, 29.97 fps, 30 fps, 59.94 fps, 60 fps | Industry Standard |
| Acceptable Sync Offset | 0 to 2 frames for editorial; beyond 2 frames usually requires correction | Best Practice |
| Timecode Drop-Frame Behavior | 30 fps drop (29.97) drops non-marked frame numbers to keep correct average frame rate | Technical Standard |
| Typical Plugin Latency | 0.2 to 7.0 samples; accumulative latency can be higher in large playlists | Plug-in Manufacturers |
| Video Playback Delay Range | 0 to 15 frames depending on system, codec, and video driver path | Pro Tools Documentation |
Comparisons and Quick Checks
Use the following checklist when feet frame and frame grid are out of sync to narrow down the cause quickly.
- Do the timecode readouts in the Edit window and the video overlay show the same time?
- Are all video tracks set to the same frame rate and resolution?
- Is delay compensation active on tracks with latency-inducing plugins?
- Does the issue persist with a new session and a single video clip?
- Have media files been transcoded or relinked without updating headers?
When to Escalate or Use Third-Party Tools
If basic alignment steps do not resolve the mismatch, consider inspecting media with a waveform/timecode reference tool, validating MXF or MOV headers, or consulting your NLE export logs. In multi-machine workflows, ensure timecode generators and LTC striping match across capture systems.
Best Practices for Ongoing Frame-Rate Integrity
Adopt habits that keep feet frame locked to the frame grid across projects. Use consistent timecode masters, standardize frame rates before ingest, log timecode accurately, and avoid unnecessary sample rate conversion. Periodically audit video tracks for accumulated latency and document pipeline offsets for future sessions.
By treating feet frame alignment as a system-level concern—spanning media, session settings, plugins, and playback hardware—you reduce rework and keep editorial decisions honest over the long term.
