I could be doing something wrong that is very basic, but I am unable to view my final AVI renderings. When I open the AVI file or import it into Premiere, it is just black video.

Is it something with the rendering settings? I use OpenGL as a setting, and I have tried all 4 of the available formats.

Is there a solution to this problem?

It sounds like you're trying to render frames which don't contain any video. Have you set your IN/OUT points correctly? Have you accidently switched off the track containing your video. What is your system configuration, processor/operating system/graphics card?

I'll have to check those things tonight, but I don't think either is the case. I'm fairly certain both video tracks I used were active, and the in/out points were set correctly. I will double check again, though.

My system is a 3 year old Dell, 1.1G, 40GB HD, 128MB RAM, Windows ME, with, I believe, a 32 MB NVidia card, but I'll check the specs on that later.

I use a DV camera.

I recall having some CODEC issues with ALAMDV2 when I started using it a year ago, which I have long since solved. That leads me to believe I am potentially having a similar issue now. However, no matter what combination of settings I choose, the final rendered video is all black.

Here's something else that might be helpful. When I used the demo version, my final product was also just black video, however, the "Chromanator" diagonal text was present, just with no picture behind it.

The Chromanator Diagonal text is there to safeguard the demo frombeing used as real. Canyou post a picture of chromantor before you render of what the screen looks like. To capture the screen, clcik control, print screen. Open up paint, and click control + v. The capture should come up. Now save it and either send it in an email to CSB, or post in on a website wiht the link here.

Understand the purpose of the Demo Chromanator Text thing. I just found it interesting that the text was present in the final AVI, but no video behind it.

Then, chalking it up to a glitch with the demo, I went ahead and purchased the full product, only to have the same black video result (w/o the Chromanatro text, of course).

Tonight, I will try to post/send a picture of the screen as suggested.

I'm certain I'm failing to see something very simple. I'm going to kick myself when this is solved!

Thank you for hanging in with me while I disappeared since asking this question!

I included a link to a page that has the screen capture.



http://www.rileydance.com/about/test.htm



This is the state of my demo file just before clicking on "render settings" and following the final instructions in the demo quickstart file.

Upon completion, I open the QT file, and I see a black background with only the grey copyright diagonal Chromanator text. There is no picture of the dude in the cape in the warehouse.

Also, the length of the movie, when I play it, is only about a second or two. I believe the in and out points are correct, and I can't seem to find the problem.

Any hints?

Thank you for your continued support.!

Is that what your screen really looks like? I dont think you have your screen resolution set properly as you can only see part of Chromonator? Also all your program icons at the bottom appear in really big font?

Not saying for sure that would be the answer to the problem you are having though.

Have you tried the "Quick Render" method, or only the "OpenGL" render. Do they both output black?

Also what graphics card do you have in your machine?
Do you have QuickTime 6.5 installed?
Do you have DirectX 9 installed?

Sorry for the many questions, but I'd like to find the solution to your problem as much as you do smile

BDOG, the screen resolution is perfect when I view it. It's a big monitor.

TIMBUK2, I have an NVIDIA, 32MB(?). I'll have to check it tonight to give the exact model.

I have DirectX 9.0, but I don't think my QT is that high of a version. I might have 5.0 or 5.5. Again, I'll have to check and post the correct info later. That might be the problem...? but...In AlamDV2, I can export as a DV AVI file. Can I do this in Chromanator, or does it have to result in a QT video?

Again, thanks for everyone's support/input.

It's working now. You guys are excellent. I figured it was something minor that I was overlooking, and turned out that when I used the "Quick Render" setting it output nicely. (thank you timbuk2)

biggrin

I had all the proper up-to-date applications installed.

I did a 3 second test movie of my own, added a few quick Alam effects, and the final AVI version is great.

Thank you for everyone's time and effort in assisting me with this!

The Quick Render is lower quality, it sound like a problem with you graphic drivers or something, it should work fine. Would be interesting to know the exact spec of you system and gfx card.

My graphics card is NVIDIA GeForce2 GTS 32MB.

I output the small movie I made into my DV camera (Sony DCRTRV330) using Premiere 6.0. I played it back on my TV and it looked pretty good.

Still not sure why it wasn't working in the OpenGL setting. Any ideas?

Update the drivers for your graphics card. BTW does your graphics card support open GL?
