I'm using Selur Hybrid to do some restoration on 8mm home videos, including some denoising, and a bit of stabilization. I had been outputting to ProResHQ because I couldn't figure out how to overcome the PCM error when trying to output to x264 (I finally figured out how to deal with that error).
Reading the forums, I learned that ProRes takes more file space than X264 but it arguably a better choice for uploading to YouTube if space and upload time is not a concern. Also the higher end of ProRes is essentially identical to the raw data, from what I heard.
Now that I can output to x264 (having solved the PCM sound error), I am finally able to create a Blu-ray spec file via the Restriction Settings menu.
My goal is to distribute the videos to my family in two formats: (1) Blu-ray discs, and (2) YouTube (or maybe Vimeo).
Should I bother creating a ProResHQ version for YouTube, or is the Blu-ray spec video file more-or-less identical for the purpose of uploading to YouTube. In other words, what do the restorers at this forum do? Multiple outputs (for Blu-ray version, YouTube version, ProRes version)?
