![]() One major hurdle was convincing the build system to not only treat arm64 as a supported configuration on macOS, but to allow building Qt for both x86_64 and arm64 in one go, producing so called universal builds.Īnother was ensuing that all our third party dependencies such as Chromium, PCRE, and OpenSSL were available and updated with arm64-support.Īnd, last but not least, we needed to add arm64 macOS into our CI so we could run all the tests, which due to lack of virtualization options required some rethinking and additional work. Luckily for us, Qt already had good cross compilation support, as well as arm64 support thanks to our iOS port, so bringing Qt up on Apple Silicon didn't initially take too much effort. The Rosetta translation layer already took care of running existing Qt applications on Apple Silicon, but we wanted native arm64 builds, to squeeze out all the power from this new chipset. I think it's nuts to capture using AIC in any case.When Apple announced the macOS transition to arm64 last year with their new Apple Silicon M1 chip, we immediately started prototyping native support in Qt - initially on developer transition kits (DTK), and later on production hardware once that became available. When the Roxio Video Capture app came out I advised Roxio to rename the settings so there was "AIC", "High-quality h.264" and "Medium-quality h.264." Had they done that I think users would have understood they weren't sacrificing quality to capture as h.264. Just pretend the AIC setting isn't an option. You can return it and buy something else to record your video as h.264, or you can choose Roxio's medium quality and record your video as h.264. The audio will be in sync when choosing this setting. Competing USB video-capture devices encode as h.264 mpeg 4, which is what the Roxio device uses in the middle-quality setting. Roxio's mistake was including one setting that captures using Apple Intermediate Codec (AIC) which creates a huge file that most devices can't even play. Roxio is NOT the only product out there and they provide no support!!! Returning this $80 product today! I have read the tips and seen the headache after headache this is causing. I am attempting to trf VHS to DVD like most all of you and am having a delay in my audio. I was hoping there would be a way to stop the software from "helping out" by inserting the green screens, but I don't see a way to do that. Still, it's a giant pain in the butt that this problem has existed so long. Since I typically introduce transitions, titles, etc between scenes, this does work. If a video doesn't have many of these, the "easy" way of avoiding the problem is to stop recording, then start again with a new recording beginning with the next scene. Every point at which the Roxio software inserts this green screen, the audio gets a tiny bit more delayed because it also introduces an audio silence that is a bit longer than the green screen. The software seems to try to "help" by inserting a short green screen break between the scenes. ![]() In the original VHS video, that break from one scene to another is also one where the recording is slightly garbled as it is transitioning. In every case it happens to me, there has been a break in the recording from one scene to another.
