HDV in AE7 – no image!

[Deleted User]

Hello Jon,

What file format was the HDV files captured into? What software did you use and compression codecs? Is sounds like the compression codecs are not installed on your system or it has an inverted Alpha channel possibly.

In Adobe After Effects
>Go to the project window>then right click the After Effects clip>and choose interpret footage>put a check in the checkbox “invert Alpha”.

You should then be able to reverse the Alpha channel to see if that what being reversed whioch was showing you the white image.

Thanks,

Leo

Thanks Leo, tried inverting Alpha but to no avail. The option is shaded out and not accessible.
I captured the footage into FCP 5.0, as a quicktime. But the versions I have on this machine (PC) have been exported as self contained QT files in both the HDV 1080 and DVCPRO HD 1080 file formats.

anymore info would help,

thanks again,

Jon

Hello Jon,

Yes invert Alpha is only available on images or clips already containing an APLHA channel I think. Is it possible if you could send me a short clip and then I can see if I can see the files on my Windows workstation here?

It sounds like you need the DVCPRO HD codec and I think this is not available on Windows natively as you need to buy a codec to play this back. Does the Quicktime files themselves play okay in Quicktime player on your Windows workstation and only have the white screen on import into After Effects?

Thanks,

Leo

Hello Peter,

I understand DVCPRO50 etc you need to buy a plugin to be able to read/write this codec.

Thanks,

Hello,

If capturing HDV on a Windows based machine, this will either by a MPEG file, and you should not need any other software to play this back.

What camera was it captured from this footage which is oplaying back white? Can you send me a second or two of the clip for me to import into After Effects for testing as it sounds unusual.

1. What camera/format was this recorded from?
2. What compression did you capture to?
3. Does the clip you have play any video back when you play independtly with Quicktime, Windows Media player etc?

Thanks,

Leo

hey,

the file was captured on fcp 5….but i thought with an qt update must run on pc too.
Mac and pc work with different hdv codecs? its not possible to send you a testclip at the moment , because i’m not able to render out a short one……
where can i download the codec?

thx

Hello Peter,

I work more on the Microsot Windows Platforms, It may be that the codec for MAC is different. However if should be the “Apple Intermediate codec” for the HDV on Final Cut Pro Quicktime file it creates from the editor.

I do not have access to a Mac to test the HDV clip. The DVCPro HD codec is only supplied by Apple with ProApps on the MAC. So it is definetly a codec issue, I think Serious Magic “HDV RACK” softwarehas the DVCPro HD coded installed with the software. Try a demo version of HDV Rack form their website http://www.seriousmagic.com I do not know other sources off the top of my head for the DvcPro HD codecs for Microsoft Windows.

Let me know how you get on?

Thanks,

Leo
