Generation loss — quality may degrade
FLV uses lossy compression, and so does OGV. Converting means decoding and re-encoding — each cycle can permanently degrade quality. Convert from the original source file whenever possible.
Some metadata may not survive
Your FLV file may contain FLV metadata metadata. OGV has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
What compression artifacts to expect
OGV lossy compression can produce blurring, blockiness (Theora). At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes.
FLV 格式，曾经是网络视频的宠儿，但随着移动互联网的普及，它在兼容性和播放体验上逐渐显露出局限性。特别是在微信、抖音等主流社交媒体平台，FLV 文件往往难以直接播放或分享，给用户带来了诸多不便。而 OGV，作为一种开放、免版税的视频格式，不仅拥有良好的压缩效率，更在多平台兼容性上表现出色。将您的 FLV 视频转换成 OGV，意味着您的内容将更容易被各种设备和浏览器所接受，无论是老旧的电脑还是最新的智能手机，都能流畅播放。这不仅能提升用户观看体验，也为您的视频内容拓展了更广阔的传播空间，让您的精彩不再受格式所限。

Full Name: FLV uses Flash Video, while OGV uses Ogg Video. Compression: FLV uses Lossy, while OGV uses Lossy. Color Depth: FLV uses 8-bit, while OGV uses 8-bit.
Your FLV file is decoded and re-encoded as OGV. FLV uses lossy compression, and so does OGV. Converting means decoding and re-encoding — each cycle can permanently degrade quality. Convert from the original source file whenever possible.
Common misconception: ""I'll convert to OGV and then back to FLV — it'll be the same"" — in reality, each lossy conversion cycle permanently degrades quality. going flv → ogv → flv will produce a noticeably worse file than the original. always keep your source file.

What Happens When You Convert FLV to OGV
Your FLV video is transcoded — video and audio streams are decoded and re-encoded into the OGV container. This is a lossy process that takes time proportional to the video duration.
Your FLV file is demuxed — video, audio, and subtitle streams are separated
The video stream is decoded frame-by-frame, then re-encoded with OGV-compatible codecs (typically H.264 for MP4)
The audio stream is decoded and re-encoded (or copied if the codec is compatible)
Subtitle and chapter data is preserved where the target supports it
Streams are muxed into the OGV container and the file is saved
