Why Convert FLV to Xvid?
FLV (Flash Video) was the dominant web video format before Adobe discontinued Flash Player in 2020. Xvid is an open-source MPEG-4 ASP codec that was the standard for sharing video files in the 2000s. Converting FLV to Xvid is useful for playing old Flash videos on standalone DVD/DivX players that support Xvid, maintaining compatibility with legacy media players and hardware, preserving web video archives in a widely supported offline format, and creating files compatible with older portable media players.

What is the difference between Xvid and DivX?
Xvid is the open-source implementation of MPEG-4 ASP, while DivX is the proprietary version. Both produce compatible video — most DivX-certified players can play Xvid files and vice versa. Xvid is free and community-maintained.
Which codec should I use?
The default Xvid codec with MP3 audio is the standard combination for maximum compatibility with standalone DivX/Xvid players. Keep these defaults unless you have a specific reason to change them.
Will the quality improve after conversion?
No — converting cannot recover quality lost by the original FLV encoding. However, Xvid's MPEG-4 ASP encoding may produce different compression artifacts than FLV's Sorenson Spark or VP6 codecs.
Can I trim the video during conversion?
Yes. Under Trim, select "Time Range" and enter a Start Time and Duration in seconds or HH:MM:SS.sss format. This extracts only the specified segment.
What players support Xvid files?
VLC, MPC-HC, KMPlayer, and most standalone DVD/DivX players support Xvid. Many smart TVs also play Xvid files via USB. For modern device compatibility, consider converting to FLV to MP4 instead.
Can I adjust the resolution during conversion?
Yes. Under Video Resolution, choose Preset Resolutions (1080p, 720p, 480p, etc.), Fixed Resolutions, Resolution Percentage, or enter custom Width, Height, or Width×Height values. Lowering resolution reduces file size — 480p is common for Xvid files.
