When Should You Use M2TS vs DV?

M2TS vs DV: Key Differences

• •The core technical difference: M2TS relies on lossy compression whereas DV 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.
• •Transparency: N/A
• •M2TS files are typically Very large, 4-8GB per Blu-ray movie while DV files range 13GB per hour in standard definition
• •Primary audience: M2TS is built for blu-ray discs, hd video archival scenarios, while DV focuses on dv camcorder capture, legacy video editing — pick the format that matches your output requirement.
