Benefits of using Imerge Pro over PhotoKey Pro

by birtanpublished on August 16, 2020

Hi I'm Axl from FX home here to take a look at some of the primary benefits of a merge pro compared to our older photo key product a merge contains loads of improvements and new features but we are going to focus on four of the major advantages first the ability to combine

Multiple foreground images photo key streamlines the process of green screen background replacement so removing a green screen and dropping a new image into the background was almost effortless emerg also makes this a very

Simple process but offers much greater versatility in emerg you can import as many green screen images as you want as separate layers and key all of them to remove the green in this way you can build a team portrait from photos of

Individuals or pose members of a group photo individually for greater control green screen photography is all about combining diverse elements into a cohesive whole and a merge allows you to do so in any circumstance in this

Example the pieces are already imported to save time but we can easily demonstrate the ability to combine multiple foregrounds we have a green screen image comped onto a new background but if we want to add a

Second subject we can import another image into a separate layer add our key to remove the green and reposition each layer to create our layout and you can repeat this process for as many layers as you want so whether you have two

People or a team of 40 the process for combining them is the same the second feature we will look at is effects masks in photo key effects were applied to the entire composite to help unify it and quickly adjust overall color and tone

Emerges powerful masking tools allow you to process any portion of any layer however you want if you want to make a color adjustment to one specific area of a layer or of the canvas you can easily do so in this instance the spill

Suppression settings we need to use also alter the color of the subjects eyes and shirt but by adding an effect mask to the chroma key we can prevent those areas from being altered by the effect so the original colors are retained we

Have some subtle light rap applied here too but if we want to add a more powerful light rap to just this upper right area where the bright light is we can add a new light rap effect and use a layer mask to limit

It to only that area third let's look at image quality in emerg pro we will use a gradient image to demonstrate this as it makes it easier to see how quality is affected during image processing photo ki

Supported the import of many raw formats but converted all images to 8-bit color for processing this allowed for quick results and decent quality here I have imported an 8-bit gradient into photo ki and dramatically increased the

Brightness now if I jump over to the effects and decrease the brightness by an equivalent amount it's apparent that the image is not looking quite as good as the original obviously this is an extreme case and in practical use you

Don't see this sort of quality loss but let's look at the same scenario in a merge the merge Pro is the first image compositor in the world that use a 16-bit color from start to finish ensuring the best possible quality

Without sacrificing speed nearly all raw image formats are supported and the raw colour data is retained throughout the editing process so you have access to the full range of raw color and tone for making adjustments to really demonstrate

This I'm using the exact same 8-bit image that we used in photo ki so this is an 8-bit image but emerg converts it to 16-bit color and all processing is done at 16-bit it's not a higher quality image so all the difference we see is

Caused by the 16-bit processing and emerge now in photo ki you can't duplicate effects so that's another benefit of a merge and in a merge rather than a specific brightness effect we have several options that give you much

Finer control and quality over that adjustment let's use levels to brighten the image then use a second copy of levels to darken it back down if I turn off the effects to compare the original with the result you can see how much

More effectively the data has been retained let's disable those levels and try exposure I'll reduce the exposure of full four stops then boost it up four stops with a second exposure effect again

The change is minimal and we are retaining virtually the entire range of luminance and color data ideally we would use the same effects in both photo ki and emerge but since both the effects themselves and how they are applied have

Been improved in emerge that wasn't possible hopefully the quality improvements are clear though and keep in mind that when working with 16-bit source images the quality retention will be even better than with this 8-bit

Image fourth we will look at the speed of a merge photo key handled all image processing on your computer central processor using all of its available speed to apply edits and effects quickly emerge leverages the full power of

Modern GPUs and by using your graphics card is able to dramatically speed up processing even though it is working at much higher quality than photo ki did so as we make adjustments to masks or effects the full resolution image on the

Canvas is updated in real time even when working with high resolution RAW files at 16-bit color making adjustments rendering and exporting are all handled very quickly so you can focus on the creative process rather than waiting for

Software these are four of the advantages of emerge but there are many other improvements and refinements as well if you haven't tried the demo yet we encourage you to do so and see just how much your workflow can benefit from
