AE and Vegas

[vegasarian]

Can anyone explain to me why, when I create a video in After Effects and view it on an external monitor it looks fine but when I imposrt the same video to Vegas and view it on the same monitor its much darker?.

How are you viewing AE on your external monitor?

It could be that you are seeing 7.5 IRE (16-235) range from AE, and when you view it through Vegas, it becomes 0 IRE (0-255).

If you are working with DV, this will most certainly be the case.

The IRE issue only affects analog NTSC to digital conversion.

I think what he is seeing is 0-255 RGB digital coming from AE into a DV format 16-235 timeline.

Usually a proper conversion is done during import. Premiere would have to do the same thing. Maybe the AE file is an unusual format.

Thanks for response Guiboche. I am working with DV and through a Canopus 110. Any idea on how I can rectify this IRE difference between AE & Vegas?.

Are you going through analog? Don't do that.

Detail your AE export settings. Show us the file on the vegas waveform monitor.

First the Vegas color bar (media generator) should show levels like this in DV mode. This is NTSC DV but PAL should look similar.

Then import your AE file and see what is going on.

The first thing I do when calibrating an external program is to send it a color bar and see what it gives back at nominal 1x settings.

OK Render done.

Here are your DV format PAL SMPTE color bars. (zero = digital 16. 100 = digital 235)


Load this into AE and see what it gives you back.

I'm not sure how the Canopus 110 works, but some hardware controllers let you decide weither to send 0 or 7.5 IRE. If so, change it to 7.5, and this should match up with After Effects.

Since, in essense, even though you're seeing different IRE ranges, the source itself isn't changing (or shouldn't be).

The Canopus ADVC imports analog NTSC or PAL video and converts to DV format. For NTSC, the 7.5IRE setting is typically used.

This has nothing to do with After Effects. After Effects is a digital program.

AE has the ability to import and export in DV, HDV or DVD MPeg2 (all 16-235 scaled)


Per Adobe

Flexible frame rates and resolutions

Specify output frame rates and resolutions (up to 30,000x30,000 pixels) to meet all international film and broadcast standards, including Cineon, HDTV, HDV, and more.

Pixel Aspect Ratios

Compensate for non-square pixels in DV, 601, HD, HDV, and other video formats using the Pixel Aspect Ratio settings.

Pulldown modes

Translate files smoothly between film and video using the 3:2 Pulldown option. Choose the 24PA Pulldown option for 24-frame progressive DV cameras.

Field rendering

Control field-rendering order for jitter-free playback on PAL and NTSC video systems.
FireWire video output

Preview your compositions on NTSC and PAL video monitors whether you're using a Windows or a Mac OS X system.

Well I dont know what happened there but I slept on it last night and just reloaded it in to Vegas this morning and its fine now. Thank you both very much for your in depth responses. I dont have time to investigate what happened right now but when I get this project finished I will and post any info I glean. Thanks again Guiboche and edDV.

This has nothing to do with After Effects. After Effects is a digital program.

I know. But I've been referring to Vegas all this time. Since he said it was darker in that program. Not AE.....
