I’m working on a simple project in After Effects 2017. After creating a composition (1920 x 1080p), I send it to the Render Queue and encode using the (AVI) default setting. I then import the AVI file in a Premiere Pro project. At first, the AVI file I created in After Effects works fine (maybe a week or so). However, over time, white horizontal lines randomly begin appearing throughout the original AVI file. It's almost as if the AVI file became corrupted. Does anyone know what could possibly be causing the horizontal white lines to suddenly appear? Thanks in advance for your help.

Hi Smarino,
Which Operating system and what are your system specs?
Please attach a screenshot of those white horizontal lines.
Are you able to see those lines, if you open that video in a media player?
Thanks,

Thanks for responding, Kulpreet. I have the following:
Dell T5500 Workstation
Windows 7 Professional w/Service Pack 1
64-bit Operating System
NVIDIA Quadro Pro K4000
48.0 BG RAM
3 TB Hard Drive (30% Used)
Rendered in After Effects
Are you able to see those lines, if you open that video in a media player? YES
The white lines begin 4 minutes into the video and last 29 frames, then quit. As I said earlier, the avi file was fine and I encoded a number of sequences with no problem. Then, the lines began appearing for no apparent reason.

is there a particular reason you are using this unpopular and inferior codec? it will create a file at enormous sizes. it is the default codec on windows and that's too bad. on Mac system Quicktime Animation is the default and I would recommend you start by using that.
5 seconds of Avi at HD1080 resolution would take approximately 1 Gg of space. the same would take with Qt Animation (one of the fastest and non compressed codecs there is) half that size. that's a very big difference if the render times would be the same with no apparent quality loss. so I would try rendering with this and see if the results are better.
