What is DVD?

DVD Video uses MPEG-2 compression in a VOB container, the standard format for DVD-Video movie discs.

What is FLV?

FLV (Flash Video) was the standard format for web video streaming before the rise of HTML5 video.

When Should You Use DVD vs FLV?

DVD vs FLV: Key Differences

• •DVD and FLV diverge on compression: lossy compression for the source, lossy compression for the target.
• •Both formats share lossy compression, so quality behavior is similar across the two — file size differences come from algorithm efficiency rather than compression philosophy.
• •How transparency is handled: FLV does not support alpha channels — transparent areas in the source will become opaque.
• •DVD files are typically 4.7GB for single-layer DVD while FLV files range Comparable to MP4 for legacy content
• •Use case fit: DVD targets dvd authoring, video backup, movie ripping and FLV targets legacy web video, online streaming — your choice depends on which workflow stage you are serving.

Advantages of DVD

• ✓DVD compresses data using lossy methods, keeping file sizes manageable for DVD authoring, video backup, movie ripping.
• ✓Industry-wide support means DVD files open anywhere — from legacy systems to the latest devices.
• ✓Small file sizes make DVD ideal for email, web uploads, and cloud storage.
• ✓From professional software to open-source alternatives, DVD works out of the box.

Advantages of FLV

• ✓At its core, FLV relies on lossy encoding — a design choice that makes it perfect for Legacy web video, online streaming.
• ✓You won't run into compatibility issues with FLV — it's a universal standard across platforms.
• ✓File size management with FLV: aggressive compression with minimal visible quality loss.
• ✓Every major application in the Legacy web video, online streaming space supports FLV natively.
