CoreMelt Lock & Load X

Faster Analysis, Better Results, More Powerful

CoreMelt Lock & Load X is the fastest and most robust stabilizer for FCP 7, Premiere Pro, After Effects, and FCP X.

CoreMelt Lock & Load X Highlights

Lock & Load X is up to 4x faster than the built-in stabilizer in FCP X and includes specific rolling shutter camera presets for most 4K and modern cameras. With optimized workflow for 4K in FCP X, Lock and Load will use both GPU on a Mac Pro system.  Lock and Load is frequently updated with new Rolling Shutter presets including the  Sony A7S, Sony AX100, Black Magic Pocket Camera, Panasonic GH4, Canon EOS 6D, RED Scarlet, RED EPIX MX, and RED EPIC Dragon.

Lock & Load, the fastest and most powerful stabilizer for FCP X, is just even better. (Updated November 2016) We’ve added support for working directly on multicam clips, batch tracking of multiple clips with one click, and optimized support for MXF and the latest R3D cameras. And if you already own Lock and Load, this is a free update for you.

Full Support for Multicam Clips

Unlike the built-in stabilizer, Lock & Load X can be used natively on angles of multi-cam clips. Apply Lock & Load just to a section of an angle that needs stabilizing, or apply Lock & Load within the Angle Editor if you wish to apply it to a complete length of an angle. Both methods are supported.

Batch Tracking

If you have many clips you need to stabilize at once, now you can paste effects or paste attributes to analyze many clips in one go. A huge time saver on many projects. To use batch processing, place lock and load onto the clip, then select the others you wish to analyze and select either paste effects or paste attributes, you will then see a window asking you if you want to batch process the clips. Once accepting this, the batch tracking window will open and show you the list of clips to be analyzed.

Optimized support for the latest RED Cameras

including the RED Weapon 8K, 4K, SCARLET-W, EPIC-W, and RED Raven 4.5K.

Optimized support for MXF files

MXF is an increasingly important standard, shot by many cameras and also often a delivery format in European countries. Lock & Load now has optimized support for MXF files, making processing of them faster and easier.

Users of FCP 7, After Effects and Premiere Pro can also access the new Rolling Shutter presets for new cameras.  Just press the “update” button in your plugin to download new shutter presets.

Rolling Shutter Reduction helps smooth out footage from CMOS cameras

  • When a CMOS chip records and image, it scans the image from top left to bottom right, when coupled with the motion of the camera, it creates the infamous “wobbly” image effect attributed to CMOS cameras.
  • Lock & Load X now includes specific shutter coefficient values for the new DSLR cameras like the Canon 7D / 5D Mark II and 550D, Sony HDCAM EX1 as well as consumer camcorders like the Legria / Vixia and helmet cams like the Contour HD.

Up to 12 times faster than Smoothcam!

  • Lock & Load X analyzes in the background so you can work on other clips while it’s working, so now more waiting around for clips to be tracked!
  • With this feature, Lock & Load X can track multiple clips in sequence, streamlining your workflow.
  • There’s also no need to re-track your clips after simply adding a transition, Lock & Load X uses advanced techniques to keep your clips tracked, meaning less waiting around

Analyzes in/out points for extra speed!

  • Rather than taking all its time to analyze the whole clip, Lock & Load X analyses only what’s in between your in/out points, so you don’t analyze unnecessary footage.
  • There’s also no need to choose tracking points as Lock & Load X intelligently chooses what to track in your clip, just drag and drop the plugin onto your clip!

Final Cut Pro X Users: Why use Lock & Load X over the built-in Stabilizer in FCP X?

  • Faster analysis, up to 12 times faster at analyzing the motion in your clip than the built-in stabilizer.
  • Better results, more power rolling shutter reduction, less wobble, zooming, and scaling artifacts.
  • More powerful, advanced features like tracking region of interest and full parameter keyframing let you handle otherwise untrackable clips.

Lock & Load X makes hand held footage look like professionally shot Steady cam in seconds.

No need to set tracking points, just analyze the entire shot and get instant results.

Even on shots with complex rotation or poorly defined backgrounds.

Check our video of before and after samples for yourself.

Lock & Load X is not only faster than the built in solutions in FCP or AE, it also gives better quality results, less zooming and blurriness due to our SmartZoom feature and can also help to reduce Rolling Shutter Artifacts from CMOS cameras including DSLR camera’s such as the Canon 5D Mark II and 7D.

CoreMelt products may work on hardware that does not meet these requirements but performance may be compromised.

Please try a trial version first to check if they meet your requirements.

For best performance, we recommend you use a graphics card with 256MB of video memory (VRAM). 512MB VRAM is required for rendering HD projects in high precision color or for configurations with multiple high-resolution displays.

The following graphics cards are not supported:

  • Nvidia GeForce FX 5200 Ultra
  • Intel GMA 950
  • ATI Radeon 8500, 9200

Some Macbook and Mac mini models are not supported due to the more limited feature-set of their built-in graphics accelerators.

Not sure what graphics card is installed in your system?

You can determine what graphics card is installed on your system by selecting the “About this Mac” command under the Apple menu.

When the system summary appears, click the “More Info…” button, which will launch the System Profiler application.

Easy to use, mixed results

While image-stabilizing programs continue to struggle with natural smoothing, Lock & Load X did deliver for small clips. If you've got short shaky clips that needs to be smoothed out or if you have rolling shutter issues– I'd recommend Lock & Load X. It's Ease of use, speed of processing and depth of options make it superior to its competitors. However, if you're looking for a way to smooth out longer clips, Lock & Load X was comparable in consistency with some of the image stabilization programs you may already have. Like I said before, to find out if it's the right fit for you, you really need to download the demo.

Build 160, August 2019 update

Lock & Load stabilizer for FCP X is now easier to use and more powerful than ever. Automatic analysis of rolling shutter artifacts means no more camera-specific settings. The best setting is calculated just by pushing the same “track motion” button as before. The interface is also modernized to not cover any part of the player window.

In Depth: Motion Stabilization Options, Part 2 of 2

Sometimes using a tripod is not an option and you’re forced to shoot hand-held. Maybe you’re shooting in an amusement park, botanical gardens, or a concert and tripods are not allowed in. Unless you have the ability to stand perfectly still, you will likely need to stabilize the footage in postproduction. Motion stabilization is used to smooth footage and remove camera shake.
