FLV до AVI Найчастіші запитання щодо конверсій
How do I re-encode FLV to AVI without quality loss?
+
Upload the FLV file and our converter applies a CRF-based re-encode targeting visually-lossless AVI output (CRF 18 by default, lower = larger / higher quality). The codec is chosen to match the AVI container — H.264 / H.265 / VP9 / AV1 as appropriate.
Which codec does the AVI output use?
+
It depends on the container. MP4 defaults to H.264 (broadest playback support); MKV defaults to H.265 for ~50% smaller file at the same quality; WebM defaults to VP9 or AV1 (royalty-free web streaming). You can override the codec choice in the advanced options before AVI conversion runs.
Will my audio track survive FLV to AVI?
+
Yes — audio is re-muxed when FLV and AVI share an audio codec, or re-encoded to AAC / Opus / Vorbis depending on what the AVI container supports. Multi-track audio (commentary, alternate languages) is preserved in containers that support it (MKV, WebM, MP4).
Can I keep the original framerate going from FLV to AVI?
+
By default framerate is unchanged (FLV 24fps stays 24fps in AVI). If you need to change it (e.g. interlaced 29.97 to progressive 30fps) the framerate option handles 3:2 pulldown and deinterlacing in the same pass — no second decode required.
What is the file size difference between FLV and AVI?
+
Same-codec re-muxes (H.264 in both FLV and AVI) produce nearly-identical sizes. Codec changes can swing things dramatically: H.264 -> H.265 typically halves the file at the same visual quality; H.264 -> VP9 is roughly comparable; AV1 is currently the smallest at the cost of slower encode time.
Will the AVI file play on iPhone / Android / Smart TV?
+
MP4 / H.264 plays everywhere natively. MOV / H.264 plays on Apple devices and most Smart TVs but not on older Android. MKV needs VLC on iOS. WebM plays in browsers but not most Smart TV apps. The "device compatibility" preset in advanced options picks the safest codec / container for your target.
How long does converting a 1-hour FLV file to AVI take?
+
Depends on the codec change. Same-codec re-mux: 30-60 seconds (no re-encode). Re-encode to a different codec: typically 0.3-0.7x source duration on our GPU pipeline, so a 1-hour FLV -> AVI finishes in 18-40 minutes; AV1 re-encodes are 2-3x slower.
What is the max resolution supported for FLV to AVI?
+
Up to 8K (7680x4320) on Pro. Free is capped at 4K per the file-size limit. HDR metadata (HDR10, Dolby Vision) is preserved where both FLV and AVI containers and codecs support it; SDR sources stay SDR.
Is my FLV video private during AVI conversion?
+
Yes — uploaded video files are processed in isolated workers and deleted within minutes of completion. No human review, no retention beyond the documented window. See /privacy/.
Can I crop or trim during the FLV to AVI step?
+
Not in the same step — use /video-trim/ or /video-cutter/ to clip the FLV first, then queue the FLV -> AVI conversion. Trim-then-convert is faster than re-encoding the whole file just to crop the output.
Why is the AVI file blurry compared to the FLV source?
+
Almost always a bitrate-too-low setting. Re-encoding a high-bitrate FLV into a lower-bitrate AVI at the default CRF compresses motion-heavy scenes heavily. Push CRF down to 16-18 (or set an explicit bitrate ceiling) and re-run to recover quality.
Does the FLV to AVI converter support subtitles?
+
Yes — embedded subtitle tracks (mov_text in MP4, SRT / ASS in MKV, WebVTT in WebM) are preserved when both FLV and AVI containers support them. Burned-in (hardsub) subtitles transfer automatically because they are part of the pixel data.
