Gradual Preview in After Results? Listed below are 5 TESTED tricks to repair it.

After Results, though a powerhouse of a program, does have its downfalls particularly with regards to previewing what you’ve produced in your numerous compositions and layers. Even with a unit of a PC/Mac, issues can run sluggish; it takes no prisoners whether or not you’ve received 8GB or 64GB of RAM. Right here at Grizzle, we’ve discovered a number of workarounds and fixes to get your render previews again up to the mark and repair a sluggish preview in After Results.

 

Simplify your venture

One of many largest causes of stutter and lag when utilizing After Results is having plenty of compositions and layers. This mixed with using results and 3D digicam work can critically decelerate your compositions and render instances. Right here’s a bullet-pointed checklist of tips on how to make your venture a bit lighter and fewer sluggish:

 

  1. Guarantee your pre-comps are solely as huge as they have to be

Pre-comp sizing is a vital issue that’s usually neglected when creating tasks in After Results. We’ve put it to the take a look at to show that utilizing pre-comps which are sized accurately are helpful performance-wise when put up in opposition to full-res pre-comps.

To clarify, say you could have a Predominant Composition that’s 1920 x 1080 px. In your important comp, you could have a pre-comp of the identical 1920 x 1080 px decision. In that pre-comp is a small animation, or nonetheless graphic that solely takes up a 500 x 500 px space, the remaining has nothing in it (alpha). Utilizing your pre-comp this manner is far more performance-intensive than utilizing a 500 x 500 px composition dimension to accommodate your animation or graphic. Let’s delve into this a bit extra…

To confirm this, we did two exams. Within the first, we had a 1920 x 1080 px Predominant Composition (60fps, 10s period). We additionally had two Pre-Comps, one was 1920 x 1080 px, and the was 500 x 500 px. Every contained the identical animated components of equal decision. We might then time how lengthy it might take to preview every Predominant Composition (the 1920px and the 500px one). All previews have been executed at 100% zoom and Full decision.

Listed below are our findings:

  • 1920 x 1080 px Pre-Comp

    • Check 1: 2.18s
    • Check 2: 2.23s
    • Check 3: 2.09s
    • Avg: 2.16s

 

  • 500 x 500 px Pre-Comp

    • Check 1: 1.94s
    • Check 2: 2.04s
    • Check 3: 1.83s
    • Avg: 1.93s

 

As you’ll be able to see, the 500px Pre-Comp carried out higher throughout the preview. While this distinction isn’t large, it does scale with bigger tasks. We took our similar Pre-Comps and multiplied them by 6 in our Predominant Composition to see what would occur below a heavier load. Listed below are our outcomes from that:

  • 1920 x 1080 px Pre-Comp x6

    • Check 1: 8.17s  –  Purge Measurement: 172MB
    • Check 2: 9.62s  –  Purge Measurement: 222MB
    • Check 3: 8.64s  –  Purge Measurement: 198MB
    • Check 4: 8.37s  –  Purge Measurement: 174MB
    • Check 5: 8.58s  –  Purge Measurement: 238MB
    • Avg: 8.68s

 

  • 500 x 500 px Pre-Comp x6

    • Check 1: 4.49s  –  Purge Measurement: 22.6MB
    • Check 2: 4.43s  –  Purge Measurement: 23.3MB
    • Check 3: 4.43s  –  Purge Measurement: 20.3MB
    • Check 4: 4.15s  –  Purge Measurement: 20.6MB
    • Check 5: 4.57s  –  Purge Measurement: 12.6MB
    • Avg: 4.41s

Sizzling Tip: When making a Pre-Comp from layers within the present composition, the brand new Pre-Comp will take the decision worth from the composition the layers have been in. Be sure to replace the brand new Pre-Comp’s comp settings to cut back the decision of it.


  1. To Pre-Comp or to not Pre-Comp…

Pre-comps are a terrific function in After Results. They can help you simplify your workflow and condense in any other case unwieldy tasks. However what impact have they got on efficiency? Does your preview run quicker when utilizing pre-comps or when simply utilizing layers? We put this to the take a look at too.

After Effects Running Slow? - Grizzle

Equally to level 1, we had two 1920 x 1080 px Predominant Compositions, one for the Pre-Comped animation and one for the non-Pre-Comped animation. This time, we changed the black circle with a picture of an apple to textual content picture rendering. So to make this extra comprehensible, say you had your important 1920 x 1080 px composition, and also you stuffed it with an entire bunch of layers all creating numerous animations. You assume to your self, ought to I pre-compose a few of these layers to make my preview run quicker? Have a look beneath to reply that very query.

Right here’s what we discovered:

  • Utilizing a Pre-Comp

    • Check 1: 2.31s
    • Check 2: 2.48s
    • Check 3: 2.19s
    • Avg: 2.33s

 

  • Not utilizing a Pre-Comp

    • Check 1: 1.82s
    • Check 2: 1.76s
    • Check 3: 1.86s
    • Avg: 1.81s

 

So at this stage, not utilizing a Pre-Comp to render an animation is extra helpful than utilizing one, however once more, not by a giant margin. We went forward and did the identical as we did in level 1 and tried placing six of the animations within the Predominant Composition. So now the Predominant Composition with the Pre-Comps in it has 7 layers (the background plus the 6 animation pre-comps) and the Predominant Composition with simply the animation layers in it has 19 layers (the background plus 3 layers for every separate apple animation).

Once more, to make this extra comprehensible, let’s say you could have your important composition with an entire bunch of layers in it, all creating six variations of the identical animation elsewhere within the comp. Wouldn’t it be smart to pre-compose the animation and duplicate the pre-comp as a substitute of getting 6 completely different variations of it? Let’s have a look, right here’s how that take a look at turned out:

  • Pre-Comped Animation x6

    • Check 1: 2.82s  –  Purge Measurement: 12.6MB
    • Check 2: 2.59s  –  Purge Measurement: 85.9MB
    • Check 3: 2.64s  –  Purge Measurement: 12.1MB
    • Check 4: 2.74s  –  Purge Measurement: 82.6MB
    • Check 5: 2.69s  –  Purge Measurement: 92.4MB
    • Avg: 2.70s

 

  • Non-Pre-Comped Animation x6

    • Check 1: 5.87s  –  Purge Measurement: 254MB
    • Check 2: 6.92s  –  Purge Measurement: 724MB
    • Check 3: 6.67s  –  Purge Measurement: 824MB
    • Check 4: 6.77s  –  Purge Measurement: 762MB
    • Check 5: 6.47s  –  Purge Measurement: 420MB
    • Avg: 6.54s

 

 

In order you’ll be able to see, it’s quite a bit higher in case you Pre-Comp a number of animations. Simply having layers in a single comp may be very sluggish compared – over 40% slower. As a takeaway, you probably have a single animation, it’s okay to maintain that in your important comp, nonetheless, in case you’re utilizing multiple, it is best to pre-comp the animation to enhance your preview efficiency.

  1. However what if I’ve received pre-comps in pre-comps? Wouldn’t it be quicker to stack pre-comps or not? Are you following ?

What on Earth will we imply?! Okay, let’s make this easy (or so simple as we will). Let’s say that you just’ve received your Predominant Composition with 1 pre-comp in it. Inside that pre-comp is extra pre-comps every housing a unique portion of your animation. For ease, let’s name this nested pre-comps. So the composition order can be: Predominant Composition > Pre-comp (Complete Animation) > Pre-comp #1 (1st animated aspect), Pre-comp #2 (2nd animated aspect).

 class=

We did a number of exams for this. The primary is as described above, with the nested pre-comps. For the second, we simply had two pre-comps in the primary composition, every with a unique animation. And for the ultimate take a look at, we simply put all of the animated layers in the primary composition (very messy!). Listed below are our outcomes:

  • Nested Comps

    • Check 1: 2.79s
    • Check 2: 3.65s
    • Check 3: 2.67s
    • Check 4: 3.10s
    • Check 5: 2.87s
    • Avg: 3.02s
  • Separate Comps

    • Check 1: 3.70s
    • Check 2: 3.74s
    • Check 3: 3.85s
    • Check 4: 4.38s
    • Check 5: 3.78s
    • Avg: 3.89s
  • All Layers in Predominant Comp

    • Check 1: 5.63s
    • Check 2: 5.87s
    • Check 3: 5.20s
    • Check 4: 5.22s
    • Check 5: 5.06s
    • Avg: 5.40s

 

So, we will see from all this that utilizing nested pre-comps is the best way to go with regards to advanced animations that use plenty of layers. Oh, and we recommend staying away from the messy comps just like the one above except you really want to.
