Hi everyone,
sadly I have a problem with transparent Video files on one PC. Fileformat is Quicktime ProRes4444 or Quicktime Animation.
On one PC it´s shown correctly (black/transparent) background, one the other the transparency is not shown (wierd blocks around it, etc.). Same result when I play the files in Caspar.
Already tried to reinstall the graphics card drivers, but this didn´t helped…
Any ideas?
(ignore the grey blocks, it´s just titles behind it that I can´t have shown)
Thanks!
Hi
Some times I have some mov files with strange alpha edges , Usually I re-render my clips at after effects with premultipled checked and not straight and then alpha plays correct
you can try
So, installed the PC completly new… now it´s just Caspar that messes up the content… Strange… -.-"
Original File is Prores4444. Doesn´t work in Caspar. If I convert it via AfterEffects to Animation Codec, the error is still the same… - but it´s also shown fine in AE.
If I create an complete new file in AE and export it via Animation Codec everything works as expected. Hmm…So somehow it looses informations in Prores4444.
Did you try with the SpeedHQ codec in an AVI container? I don’t recall which variant works best.
I have experienced the same problem and uncheck the premultipled do help。
Quite old topic, but seams still relevant … while testing for a project with 2.5.0 stable I found out that ProRes4444 can contain Straight OR PreMulitplied Fill, depending on the render settings in AfterEffects (AE).
Caspar plays the layer back as it is. If ProRes4444 is Straight > Caspar layer output is Straight too. If ProRes4444 is PreMult > layer output is PreMult. As most other stuff incl. templates and especially multilayering are always PreMult inside Caspar it only makes sense to render ProRes4444 with PreMult Fill for use in Caspar.
Caution: If Media Encoder(ME) is used to output from AE - Output is always Straight! Rendersettings from AE are ignored in ME. And ME itself has no option to select for Straight oder PreMultiplied output !
Besides that ProRes4444 works well in 2.5.0 - just use AE own render cue and be sure so set output to PreMultiplied.
