Thats right! Thanks Walter!

Very interesting indeed. Is there any news out there why this is happening from a technical point of view?

[Bernhard Walzl]

yes, VLC will play it correctly.

however, the problem started off that I have two videos: one is an intro and the other is a logo (which has video footage in the background). one has a black background, the other one is transparent whereas both use the animation codec.

when I put them in the timeline (premiere cs6) next to each other, export as h264, their grey tone will change.

So I am just trying to find out where the root of this problem sits, to solve this issue.

No need to propose me a workaround, i want to know why things are how they are.

Any help with this is highly appreciated.

Because through the middle runs a solid black layer in the background. the upper and lower bit are kept transparent.

Thanks Walter!

//edit: sorry I just realized my default font was not a standard one, feel free to change it, it will produce the same result.

It is white text with 40% opacity. Through the center is a solid black in the background while the upper and lower part stays transparent. Rendered as Animation, preserving the Alpha channel, and when viewing in Quicktime it will look like this:

My question: Why.

[Bernhard Walzl]

I have exported and viewed the exact same way.
After rendering out the first version, I have created a black solid in the back, then for the export, I have duplicated the old render entry to get the exact same result.
The picture I have taken is a screenshot what quicktime displays.

Can someone reproduce this? I am happy to upload my after effects file…

[Bernhard Walzl]

Both were encoded using the codec ANIMATION (plus alpha) with the same settings. The picture is done with photoshop to demonstrate the difference. But I can render it out by placing the solid black half behind the icon.

Thanks for your replies! This is great information.

However, I need to purchase for work a camera rather soon, so waiting a year is no option unfortunately.

If NXCAM doesn’t do it, which format would you recommend (which is readily available on the market) to avoid transcoding to prores prior editing?

At work I have Premiere Pro and Final Cut X available, running on a small Mac mini (late 2012). Changing to a faster machine is no option.

Cheers,
Bernhard

Hi there!
I installed a quicktime plugin to make .mst work unfer FCP.

Luckily it is just an assembly of (many, many) files and not an actual edit.

So now I want to export the films (each has a runtime of about 2 hours).

When I want to export in h.264 on my old mac book pro (late 2008) it will take a loong while (I guess about 24 hours).

Is there any export option in FCP to not encode the film again but rewrap it into a h264 as AVCHD is basically already a H264 codec? Would this speed the process up?

Thanks!
