HDRinstant User Guide: Standalone Version 

HDRinstant standalone version will allow you to capture the best frame of your video, enhance it with HDR and apply tone-mapping options.

I. Pick your video

For best results, we recommend you to use :

  • A high-quality video: 4K, UHD or HD.
  • A video with a high number of Frames Per Second (or FPS). This will allow you to easily select the image you want to process.

HDRinstant processes videos of various exposure levels. However, our technology will work even better with underexposed video.

II.   Upload your video in HDRinstant

  1. Launch HDRinstant.
  2. Click on Open a File or drag and drop your video.

III. Select your best frame

Once you have uploaded your video, you can select the frame you want to extract and enhance with HDR.

  1. Select the frame with the help of the cursor or the playback bar.Note that to help you select that best moment, you can mark up to four different frames. Double-click on the cursor or on the video and a marker will appear on the playback bar. Compare those frames and select the best one of them.
  2. To get the sharpest image, use the tool Sharpness Check. This tool suggests sharper frames near your initial chosen frame. 
    1. Click on Sharpness Check. Several frames appear, close to the one initially selected.
    2. Select the one you want to process.
  3. Click on next.

IV. Process your image with HDR

This tab presents several processing settings.

  1. Choose the processing speed from the drop-down menu.

The processing speed is the computing time required to process your HDR image. We recommend trying Fast first: some pixels blocks may appear where there is movement. If it is not satisfying enough for you, then try Medium: it is a good compromise between speed and quality. Slow makes the quality even better, but the calculation time can be quite long, especially if the image contains a lot of pixels.

  1. Define the number of images to stack in the Noise Reduction section.

HDRinstant technology uses a high-end technique of image stacking in order to improve image quality and reduce noise.  You can set the number of neighboring frames before and after your selected image. The higher the number of stacked images, the more relevant the HDR result will be. However, make sure that the selected neighboring frames are similar to your initial selected image.

  1. Select the anti-ghosting option in the Processing of Moving Subjects section. 

This tool allows to increase or reduce blurs from moving subjects. The higher the anti-ghosting, the sharper the moving subjects will be. A long exposure simulation will allow you to get blurred on your moving subjects.

  1. Click on Compute.
  2. Once processing is complete, we recommend you saving your final HDR. You can save it in various formats: .tiff, .jpeg, .psd, .hdr, .png and .bmp.

V. Retouch your photo

In this tab you can use tone-mapping presets.

  1. Select a preset or define your own settings in the right-hand-side window.
  2. Once you are done, export your photo by clicking on the export button, top right or bottom left. You can save your photo in various formats:  .tiff, .jpeg, .psd, .hdr, .png and .bmp.
