Seams to be some sort of problem with pixel aspect ratio conversions.
If I use Aja Lhe in After Effect for outputting 1080 to refernsmonitor, then my rampreview don’t play reeltime. Atleast not if AE composition is set to native dvcpro hd (nonsquare). But if I change the composition settings to square it starts to play in real time. Is this normal? As I understand you should keep the native aspect of you sourceclip and use the compensate switch to make ae display the picture in 16:9. But doing that i get slow playback..
I have not had any problems before with reeltime rampreviews so I started to suspect the driver. So I uninstalled the aja 8 driver and reinstalled the 7.5.1 driver.
With the Aja 7.5.1 drivers Ae plays at 9fps (rampreview) with native dvcpro hd nonsquare. But if I change the compostion settings to square it plays in realtime. I usally put the compostition to square and 1920×1080 so I didn’t notice the slow playback until now. If you ramplayback from prores 422 square it runs realtime aswell.
proress is another story thoue wich shows up purple in cs5. Atleast with the 7.5.1 drivers. Because the problem lies in 8bit you can switch to 16bit but then i loose the reeltime rampreview.
The new aja 8 driver gives slower rampreviews. Even with composition set to square i only come up to 22 fps with ajas version 8 driver? So I stay with Aja 7.5.1 driver.
If I want to run my dvcpro hd native (nonsquare) but still use aja and have reeltime previews. What suggestions do you have?
You don’t have the same choices in AE with Aja driver version 7.5.1 and 8.
Aja driver version 7.5.1 gives an option AJA Kona 1080i 25 8 bit.
In Aja driver version 8 i can’t find this so Instead I choose AJA 1080i 25 RGBA. Is that 8 bit?
