What is F4V?

F4V files are built around lossy compression. Designed for legacy flash video, adobe media server streaming, they use the video/x-f4v MIME type and typically range from varies by content.

What is 3G2?

3GPP2 (3G2) is a multimedia container format developed for CDMA mobile networks, supporting video and audio streaming.

When Should You Use F4V vs 3G2?

F4V vs 3G2: Key Differences

• •F4V uses lossy compression while 3G2 uses lossy compression — both take the same approach to file size management.
• •Since both F4V and 3G2 use lossy compression, the quality characteristics are comparable — differences in file size come down to how efficiently each format implements compression.
• •Alpha channel support: 3G2 lacks transparency support.
• •File sizes: F4V files typically range N/A and 3G2 files Small, optimized for mobile.
• •Primary audience: F4V is built for legacy flash video, adobe media server streaming scenarios, while 3G2 focuses on legacy mobile video, mms messages — pick the format that matches your output requirement.
