I do this routine every other day after I finish with Animate Toggle Key Frame, export.
In this composition windows is the video.
When I do export, render in the composition windows is the video.
I always change lossless from AVI to Quicktime.
As I am looking at the composition window there is the video colors and subjects.
Then I click Render the video in composition becomes Black.
After the render the rendered video is with audio and no video.
What's to do?
Your sample video shows you adding the Composition to the Render Queue. You are looking at the Footage Panel. I have no idea what is going on in the Composition. You need to be looking at the Composition Panel. You could have a layer set as a guide layer. There could be no content.
To render a copy of the footage, you must select the footage in the Project panel, then drag it to the Render Queue.
If you are always editing the Output Module, you should go to the File menu and edit the presets. It will save you time.
If I open all my projects from the last week I am able to render.
This current one I cannot figure out what to do to get the video to render.
In the Project Panel if I drag the file into Composition it plays the original film.
If I click on the video that I did animation work with in the Composition Panel the video only plays as it should in the Preview Panel as a Layer. If I click on Compostion Panel the video becomes black playing only audio. I include a video showing the issue.
In your video, it looks like the Layer is hidden.
Enable Video in the AV Controls and you should see picture as expected in the Composition panel and in rendered movies as expected.
How to do enable video in AV controls?
Don't know how to do that.
For those who may read this - I got no useful answer.
Since the days after this posting I did additional reel work. The 8mm converted reels to MOV were all 3 min 20 seconds. With AE I use only one reel per project. Later I combine the rendered reels into one complete video.
Before this issue and after this issue I had no issue with rendering. I could not fix this one video reel with a rendering. What I did was to screen capture the video as it played - saved it as MOV - and that did work.
