FLV to AVI Conversion FAQ
What does the FLV to AVI converter do?
+
It transcodes a FLV video into the AVI container. Resolution, frame rate, and aspect ratio are preserved by default — useful when you need a different format for a target player without quality loss.
Will resolution and frame rate be preserved in the AVI?
+
Yes. FLV → AVI keeps resolution, frame rate, and aspect ratio unchanged by default. To change them, use the Resize or Speed tool on the result.
Will the FLV play smoothly on modern devices after converting to AVI?
+
Yes. Legacy FLV files often fail to play in modern browsers and on iOS / Android. AVI uses widely supported codecs that play natively on phones, tablets, smart TVs, and every modern browser.
Will the converted AVI be a different size than the FLV?
+
Modern codecs compress better, so AVI from a legacy FLV is typically 30-60% smaller at equivalent quality. Conversions in the opposite direction can grow the file.
Can the AVI hold more than one audio track?
+
Yes, and it is a real upgrade over FLV. AVI treats every audio stream as a first-class track, so an original-language mix, a dub and a director commentary can live in one file with the player switching between them on demand. AVI is trivially simple, which is exactly why ancient camcorders, capture cards, DVD ripping tools and Windows-era software all still emit it.
Is there any point converting between two legacy formats like FLV and AVI?
+
Only if a specific piece of equipment demands the target. Both formats come from the same pre-H.264 era, so neither conversion buys efficiency, quality or future-proofing — it buys compatibility with one particular device. If the goal is to keep the footage usable long-term, convert to a current container instead of sideways. No current browser, phone or TV can play FLV — anything still in this container has to be moved out of it to remain watchable. AVI has no native support for modern codecs, variable frame rate, soft subtitles or files over 4 GB without hacks, and its per-chunk overhead bloats the file.
Is there a file-size limit when converting FLV to AVI?
+
Anonymous uploads are capped at a generous default; signed-in free accounts get a higher cap, and Pro accounts have no per-file limit. Browser memory is usually the practical constraint long before our server-side limits kick in.
Can I batch-convert several FLV files to AVI at once?
+
Yes. Drop or pick multiple FLV files in one upload — the converter processes them in parallel and returns a ZIP of the AVI results. There is no need to repeat the upload step per file.
What happens to my FLV files after the conversion?
+
Uploaded files and AVI outputs are auto-deleted after a short retention window. We do not inspect, share, or train on user files. Direct download links are time-limited and tied to your session.
Will my AVI play on phones, tablets, and TVs?
+
AVI plays in most desktop players but is sometimes unsupported on mobile and TV. For broadest reach, consider MP4 instead.
Do I need to install software to convert FLV to AVI?
+
No. The converter runs entirely in your browser plus our cloud — no plugin, no install, no admin rights. It works on Windows, macOS, Linux, ChromeOS, iOS, and Android.
Do I need an account to convert FLV to AVI?
+
No. FLV to AVI conversion is free and works without an account. Signing in unlocks higher file-size caps, batch history, and API access.
