When Should You Use MTS vs FLV?

MTS vs FLV: Key Differences

• •The core technical difference: MTS relies on lossy compression whereas FLV 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.
• •How transparency is handled: FLV does not support alpha channels — transparent areas in the source will become opaque.
• •MTS files are typically High, 100MB per minute of HD video while FLV files range Comparable to MP4 for legacy content
• •Primary audience: MTS is built for hd camcorder video, consumer video editing scenarios, while FLV focuses on legacy web video, online streaming — pick the format that matches your output requirement.
