When Should You Use SWF vs VC1?

SWF vs VC1: Key Differences

• •SWF uses lossy compression while VC1 uses lossy compression — both take the same approach to file size management.
• •Since both SWF and VC1 use lossy compression, the quality characteristics are comparable — differences in file size come down to how efficiently each format implements compression.
• •How transparency is handled: VC1 does not support alpha channels — transparent areas in the source will become opaque.
• •VC1 files tend to be differently sized than SWF
• •Primary audience: SWF is built for flash animations, legacy web games, interactive content scenarios, while VC1 focuses on blu-ray video, windows media, xbox game videos — pick the format that matches your output requirement.
