I have a comp loading an apple prores (apcn) that was working fine in win7 using fusion v7. After upgrading to win10 it no longer works - in fusion v7 or v8. Does quicktime need to be installed? If so, what is a good workaround? It seems that apple does not support quicktime in win10.

thanks,

you can install QT in 10. I'm running 7.7.6 just fine. I believe MS provided a patch back in Oct to get it to work since Apple could care less if QT works. But one option if I remember correctly to bypass installation errors from Apple is to install it in Windows 7 compatibility mode.



I just googled and found this on Apple's site: https://discussions.apple.com/thread/71 ... 0&tstart=0

Correct, which is why the industry insistence on using it is puzzling.

Thanks Jeff and Chad

All this comp does at this point is resize the QT file and render it as a series of jpgs for use in syntheyes. But later, i would like to integrate 3d elements into it. My preference is to convert the QT file to a format that can be handled directly by fusion. To that end i found a conversion utility called ffmpeg. It has many options for the output file:/ Is there an output format that is generally suitable for use in fusion and resolve?

thanks,

I'd say it depends on what you ultimately want to do with the output, or who will handle the file after you're done.. I usually provide QTs as Prores or dnx (avid) codec from the PC or Prores from the Mac depending on who I'm working with.

ok, so it's not the qt player that fusion needs, it's the codec. And it's not just any .mov codec, because the video plays in vlc, it's apple's codec that fusion is looking for. How do i know what codecs are available to fusion? Ultimately i want to post full hd or hd720 to the web, probably youtube.
Now it looks like i should use ffmpeg to convert the .mov to an image sequence, do my tracking, 3d and compositing with that, then use fusion or resolve to output as mp4.
Does that sound reasonable?

thanks

You'd do better using ffmpeg or a dedicated YouTube utility to make the mpeg4 files from the image sequences.

You can even run ffmpeg as a post render task from inside Fusion.

that's my plan then. Thanks to both of you for getting me headed in the right direction

Things were going along fine with ffmpeg until i needed to extract a section of video from a larger video. I had problems getting the beginning of the extracted clip to start at an iframe. So rather than continuing to screw around with it i installed qt and used Resolve - its editing capabilities make that process transparent (as did Fusion, but Resolve seems easier). You mentioned ffmpeg being a better choice than Fusion for re-encoding the sequence to mpeg4, does that stand for Resolve too? Are there reasons not to use Resolve for all of the de/re/trans coding it can do?

btw, it seems that Fusion is able to get each frame of a video, encoded with intra-frame compression, to land on an iframe. Is that the way it is or is Fusion reconstructing its loaded frames from b/p-frames when it doesn't have an i-frame to load?

thank you
