After I render the video, the effects that I added to the video have magically disappeared even thought they still show up in after effects. Help please!!

Question

Hello!

In after effects I added some muzzle flashes and other effects to a video. I than rendered it out. When I watch the finished video, some of the muzzle flashes and effects randomly disappeared. I even went back into after effects to make sure that the effects were actually there and they are. But they don't show up when I watch the rendered video. I have rendered it over 5 times now and I am still getting the same issue. And also, I have done this same sort of stuff before with all the same settings and it worked just fine with other videos. The file type I exported it as is AVI because it doesn't show any other options when I render the video. But I have rendered plenty of other videos as AVI files and they were just fine. Someone please help!

I think you're getting off track from my original issue. My Issue is that I spent over 6 hours editing this video and now all of the things that I added to the video have disappeared after I render it out. That is my issue. It doesn't really have anything to do with fps or pre-comps because when I preview the video in AE it show me everything that I added, but after I render it and watch the rendered video, the things that I added disappeared. That Is my issue.

All the things? or just some of them? Are these effects or footage of flashes? it's hard to tell and get the full picture because of the way you setup you project.

I understand you don't want to start over or take steps back in your project. Do what you can but I gave advice for you anyone who is dealing with a stop motion workflow. The way you edit and setup your footage is prone to all sorts of errors.

the frame rate and precomps relation to your issue: I suspect the 13.043fps can create this sort of problems Because it is a not whole fps number and not a common frame rate that is supported with some codecs. So maybe the rendered footage is not the same frame rate and this means skipped frames. The precomps are related because there are one inside the other several times and this makes it difficult to detect where is the mismatch. it is still unclear where are the exact layers that are missing. where are these muzzle flashes? Is this a video or an effect?

Try this:

import your rendered video to Ae and see what frame rate it interprets it in. If it's not the same then it skipped frames=skipped some of the layers. also try and Trace the exact points in time where you missed some layers by placing the rendered video above the original comp and dig inside the precomps and look for frame rate mismatch.

they don't show up when I watch the rendered video.

a common user error is to accidently check the layer as Guide layers.if you see this symbol

then right click on the layer and check off "guide layer"

if this is not the case, show us a full screenshot of your Ae interface so we can examine it.

The file type I exported it as is AVI because it doesn't show any other options when I render the video.

this does not sound normal. where is this video going? if you are creating a lossless file you are better off using Quicktime and for a codec - Animation is a popular one. you need to install Quicktime to have these options. (on Windows you had better install just the essential components because there are some security issues associated with Quicktime player). if your intention is to playback the video for your entertainment of upload to some service online, then you should export using Adobe Media Encoder and you don't have to render it in Ae before you do that. see here for exporting options in Ae: Basics of rendering and exporting in After Effects CC
