[Confirmed] Problem with converting ProRes with 10.0
Hey Guys!
This is my first time posting here so I hope I can find some help.
I am part of a press group where we receive trailers and clips for upcoming films in order to promote them. A lot of these files are provided in ProRes directly from the studio themselves. Before the 10.0 update, I've never had a problem with final encode. But I've noticed since I've updated, I get these weird artifacts in the encode. Its shows a few random rectangles in the image when it cuts to a different shot. Heres a screenshot of what I'm talking about.
Like I said before, I'm using the same settings I did before i updated and I've never had this problem. So I figure its has to be something in the update causing the problem.
If anyone knows how to fix this, I would appreciate it. Otherwise I may need to downgrade to the last version of handbrake.
Heres the activity log.

Thanks,
Jason

Re: Problem with converting ProRes with 10.0
... i won't be of any help regarding the main issue, as there isn't any error in the log...
but i will say that you shouldn't use AAC(avcodec)... especially if the output is intended to be heard by other people in some cases, it won't sound like garbage... but to be safe, just use AAC(FDK)... EDIT: and is there a particular reason why you're using the mono track instead of the stereo track?

Moving to bugs.
Are you able to provide a sample that doesn't violate anyone's copyright?

Or a really short sample, like 10 seconds or so.

Re: Problem with converting ProRes with 10.0
Im glad you pointed that out. Most of the trailers contain anywhere from 4-8 channels. Each channel contains a different audio element (EX. Isolated Dialogue, Music, Sound FX, or a Final Stereo mix etc...) It looks like I might have accidentally selected the mono dialogue track instead of the final stereo mixmoneymatt4life wrote:EDIT: and is there a particular reason why you're using the mono track instead of the stereo track?

I noticed this problem a lot when I converted the recently released Ant-Man trailer. But I've already deleted it. I can re-download and encode again to provide a sample.Rodeo wrote:Or a really short sample, like 10 seconds or so.

Re: Problem with converting ProRes with 10.0
by sample, i assume they mean losslessly cut out the part where you're getting the artifacts... not an encode with the artifacts present so no one knows what's going on with the decoder/whatever
Re: Problem with converting ProRes with 10.0
Is there really a place distributing film trailers in ProRes?

Re: Problem with converting ProRes with 10.0
Yeah. But you need to be a member of the press to access it. But it's usually only Disney that distributes then in ProRes. Everyone else usually posts them in DVCPro.Rodeo wrote:Is there really a place distributing film trailers in ProRes?

Re: Problem with converting ProRes with 10.0
UPDATE: So I Re-Installed the previous version of Handbrake and tried to encode the same trailer again. This time I had no artifacts. So it has to be something with the 10.0 update. Until this is fixed it looks like I'll have to settle for an older version. Anyway here is a comparison screenshot.

Re: Problem with converting ProRes with 10.0
This remind me an old bug related with multithreading decoding when ProRes was added to FFMPEG about 3 years ago.

Re: Problem with converting ProRes with 10.0
Yes, but that one's been fixed. Seems like a new bug.
Re: [Confirmed] Problem with converting ProRes with 10.0
Marked as confirmed.
