To: vrender->video_out->set_clear_color(clr_color, 0x00);<br>
<br>
1. I opened old projects to see how they behaved. It seems good.<br>
2. I tested Open EDL feature using EDL_Files.zip by RafaMar in <br>
(ManrisBT0000558) as a sequence on the top of my project. It seems to <br>
work good.<br>
3. Test with Mixer Viewer as shown in Tutorial "Cinelerra GG: Multi Cam <br>
editing (with Proxy)" <a href="https://www.youtube.com/watch?v=49EExsRsjlY" rel="noreferrer noreferrer" target="_blank">https://www.youtube.com/watch?v=49EExsRsjlY</a> . It <br>
seems good.<br>
<br>
4. BUT I noticed a problem when the Nested clip with fade In is pasted <br>
in the Master project; however, that is there also without the mod.<br>
My test file and screenshot in the compressed file to the link<br>
<a href="https://transfer.sh/vURPjc/Test_AlphaChannelUsingFadeOnNested__Cin_2022117_and_0x00.tar.gz" rel="noreferrer noreferrer" target="_blank">https://transfer.sh/vURPjc/Test_AlphaChannelUsingFadeOnNested__Cin_2022117_and_0x00.tar.gz</a><br>
<br>
The project uses the same Title effect for the Nested Clip as for the V3 <br>
Video track. In the timeline there are three markers (labels). When the <br>
Insertion Point (the cursor) is pointing on the 2nd marker, the two <br>
texts should have the same white colour. Unforunately this does not <br>
happen. It is weird, but I think it would be useful to keep this mod.<br>
It is possible to have the right behaviour in the Nested clip by <br>
changing the "Overaly mode", in the V4 video track, from Normal to <br>
PorteDuff...->SrcOver.<br>
Finally, I wouldn't close the ticket "0000558: Problem with alpha <br>
channel when using a nested or reference EDL" <br>
(<a href="https://www.cinelerra-gg.org/bugtracker/view.php?id=558" rel="noreferrer noreferrer" target="_blank">https://www.cinelerra-gg.org/bugtracker/view.php?id=558</a>) because, in my <br>
opinion, it is not completely solved. We could add a note about. Thanks!<br>
<br>
About "... IgorBeg were able to see that the correction fixes render <br>
using PNG, EXR, and TGA", I don't know what you are referring to. I <br>
haven't tested anything about. Sorry.<br>
