Hi All, The RAW video discussion had me thinking about resolution and bit rates for video and I had some questions. These are not how-to questions but general video questions. I'm an amateur so the contest of these questions is around video for home movies and social media, stored and shared as data files, and displayed on computers, tablets, and TVs.
1. Why does it make sense to convert from a lossy format to raw? You're not gaining any more detail. 2. Does re-rendering video over and over at the same resolution, frame rate, and bit rate cause degradation? For example, if I want to make several changes to the video, like colour correction, splicing out sections, transitions, titling, etc. should I be trying to do that all in one command? 3. I understand that -c copy is a great way to eliminate time and preserve detail but what's the best way to do this when converting from one codec to another, or when performing editing or other changes? 4. How important is it to keep standard resolutions, frame rates, and bit rates? Do hardware decoders do better with those? Do software decoders handle weird resolutions better? Will strange decoding artifacts appear more often with non-standard parameters?
