When Should You Use VP9 vs VOB?

VP9 vs VOB: Key Differences

• •The core technical difference: VP9 relies on lossy compression whereas VOB uses lossy compression.
• •Neither format changes compression philosophy — both are lossy compression — so any size differences are due to encoding efficiency, not a shift in quality approach.
• •Alpha channel support: VOB lacks transparency support.
• •VP9 files are typically Smaller than H.264 at same quality while VOB files range 1-2GB per hour of DVD video
