# Previewing Files

EditReady allows you to preview your files before conversion. To access the player, select the clip and choose `Open Preview` from the `Clip` menu, or press `Command-3` on the keyboard.

### Applying LUTs During Playback

Click the `Add LUT` icon to apply a LUT to your file during playback. This allows you to quickly preview any conversions you'd like to apply. For details on LUT support in EditReady, see [Converting Media > Additional Batch Options > LUTs](/editready/converting-media/additional-features.md#luts).

Keep in mind that LUTs can be compute-intensive, particularly on 4K files. Slower computers (or computers with slower graphics cards) may have trouble with realtime playback.
