Watermarking DNxHD36 QT leads to black movie

Hi,

I am trying to watermark a bunch of QTs (AVID DNxHD36 1080P 24) but as soon as I set a filter for this the result is a black QT. Actually you see the first frame correctly which then smoothly fades to black and the rest of the film will stay black with the text burn-in I've set.

This happens with any other filter as well.

The preview monitor shows everything is fine but the rendered QT is messed up.

A friend tried on a different system with Compressor 3. Same result.

Any ideas? This renders this "pro" app pretty much useless for me.

Thanks!

(Using Compressor 4.0.7, AVID DNxHD codecs are installed)

Compressor, OS X Mountain Lion (10.8.4)

Same here. Starts out OK and then goes south. A logo shows but the BG is black.

BTW:

When you do the same thing but transcode to ProRes at the same time the result will turn into a dark red and black freezeframe with the burnin.

messed up.

No problems here with either the text overlay or the watermark filters...

For images are you using a png?

David,

did you do this with the exact same type of QT like I did (see the OP)?

I wonder what you're doing differently?

I've reproduces this on 3 different machines with Compressor 3 and 4. ALl show the same issue. What version are you using and did you positively use a DNxHD36 1080P 24.00fps QT?

Regarding your question: On my system it doesn't matter what kind of filter I use. As soon as there's anything set (text, timecode, or anything else from the filters list) the resulting QT is black.

Thanks!

Apple has kindly given me a full refund for my purchase since the programm is completely useless for me in it's current form.

So problem not solved but decent customer service.

Yes, this is still an issue with the latest version of Compressor. It's been like this for a while and is very frusterating. But there are a couple ways around this.

One, if you paste an empty text track in the Quicktime movie with Quicktime Pro 7 and then save it (saves instantly, no rendering) and bring that movie in to Compressor it will work with the timecode and text burn in filter. Here is a thread that discusses how to do this:

(See the 9th and 10th posts in that thread for instructions.)

And two, instead of doing the burn ins in Compressor I use this app Toki TC. Here's a blog post I did on using this with Compressor if it suits your needs.

Let me know if any of this works for you.
