A Simple Image Sequence Player Made for 3D Artists

If you render image sequences, you know the pain:
scrubbing folders full of frames, guessing playback speed, or opening heavy software just to check timing.

This Image Sequence Player is built to fix exactly that.

Play Your Renders at the Correct Framerate

Drop in a folder of images and hit play.
The player runs your sequence at a true, time-based framerate, so 24 fps actually feels like 24 fps—no drifting, no guesswork.

Perfect for:

  • Animation previews
  • Simulation checks
  • Camera move timing
  • Look-dev iterations

Smooth Playback, Even for Heavy Sequences

For larger renders, you can prerender the sequence into a cached video with one click.
Playback instantly becomes smooth and responsive—great for long or high-resolution sequences.

You can still scrub frame-by-frame when you need precision.

Loop, Scrub, Step — Instantly

  • Loop animations for motion checks
  • Scrub the timeline naturally
  • Step frame-by-frame forward or backward

No setup, no importing, no project files.

Export a Quick Video File

Need to send a preview to a client or teammate?

Export your sequence directly to:

  • AVI (fast, no recompression)
  • MP4 (easy sharing, universal playback)

What you see is exactly what you export.

Why Artists Like It

  • No timeline setup
  • No codecs to fight
  • No heavy software just to “check a render”
  • Fast, clean, and predictable

It’s the kind of tool you keep open next to Blender, Houdini, or Unreal—just for viewing.

Built for One Job, Done Well

This isn’t an editor.
It’s a viewer that respects time, framerate, and your workflow.

If you work with image sequences, this tool saves time every single day.

Syntheyes keyboard shortcuts

I have been using Syntheyes again after many years of focusing on other tools and I often struggle to find information on keyboard shortcuts for it online. So here is a little collection of shortcuts that I had to look up myself:

Add new manual tracker

When doing supervised tracking, you don’t want to keep switching to the magic wand tool every time you need to create a new tracker. Instead, just hold down the “c” key on the keyboard and click somewhere in the image.

Hide the crosshairs from the image

When doing supervised tracking, you often want maximum focus and all the little crosshairs and other markers on top of the image can be distracting. Hide the crosshairs from previous auto-tracks with the “j” keyboard shortcut.

Hide locked trackers

Unfortunately I haven’t been able to find a feature that will automatically hide all the locked trackers, but at least there is this workaround: select all the trackers and then hide them with edit –> hide selected.

Track forwards and backwards

If you want to just track one frame forwards, there are several options. You can scroll with the scroll wheel of your mouse, or press . (period) or press “d”. To change the direction of tracking to backwards, switch the direction of the arrow pointing right at the bottom timeline panel. Now tracking will be recorded backwards when you press “s” or , (comma).
