WebM جي طرف FLV تبديلي بابت اڪثر پڇيا ويندڙ سوال
How do I re-encode WebM to FLV without losing video quality?
+
Upload your WebM file and the converter runs a CRF-based re-encode targeting visually-lossless FLV output (CRF 18 by default, lower values = larger file / higher quality). The codec is chosen to match the FLV container — H.264 for broad-compat MP4, H.265 for size-efficient MKV, VP9 for WebM, AV1 for newer pipelines.
Which video codec does the FLV output use?
+
It depends on the FLV container. MP4 defaults to H.264 for the broadest playback support across phones, browsers, and Smart TVs. MKV defaults to H.265 / HEVC for roughly half the file size at equivalent quality. WebM defaults to VP9. The advanced options expose explicit codec choice if you need to override.
Will my audio track survive WebM to FLV conversion?
+
Yes. When WebM and FLV share an audio codec (e.g. both carry AAC), audio is re-muxed with no re-encode — bit-identical. When the codecs differ, audio is transcoded to AAC / Opus / Vorbis depending on what the FLV container supports. Multi-track audio (commentary, alternate languages) is preserved.
Can I keep the original framerate when converting WebM to FLV?
+
By default yes — a 24fps WebM stays 24fps in FLV; a 60fps WebM stays 60fps. If you need to change rate (e.g. interlaced 29.97 → progressive 30, or 60 → 30 for upload limits), the framerate option handles 3:2 pulldown, deinterlacing, and frame-blending in the same encode pass.
How much will the file size change going from WebM to FLV?
+
Same-codec re-mux (WebM H.264 → FLV H.264 just changing container): nearly identical size. Codec change can swing dramatically: H.264 → H.265 typically halves the file at the same visual quality; VP9 is roughly comparable; AV1 cuts another 20-30% but is slower to encode.
Will the FLV file play on iPhone, Android, and Smart TVs?
+
MP4 / H.264 plays natively on every modern device. MOV / H.264 plays on Apple devices and most TVs but not always on older Android. MKV needs VLC on iOS. WebM is browser-first. The advanced options include a "device compatibility" preset that picks the safest FLV codec / container for your target.
How long does converting a 1-hour WebM video to FLV take?
+
Same-codec re-mux is near-instant — 30 to 60 seconds for a 1-hour file. A full codec re-encode runs at roughly 0.3-0.7x source duration on our GPU pipeline, so a 1-hour WebM → FLV finishes in 18-40 minutes depending on resolution and target codec.
What is the maximum resolution supported for WebM to FLV?
+
Up to 8K (7680×4320) on Premium plans. Free conversions are capped at 4K (3840×2160) by the per-file size limit. HDR metadata (HDR10, HDR10+, Dolby Vision when present) is carried through where both WebM and FLV containers support it.
Is my WebM video private during conversion to FLV?
+
Yes. Uploaded video files are processed in isolated workers, never viewed by a human, never indexed, and deleted within minutes of completion. The retention window is documented at /privacy/ and we publish no training corpus from user uploads.
Can I crop, trim, or rotate during the WebM to FLV conversion?
+
Not in the same step — use /video-trim/ or /video-cutter/ to clip first, then run the WebM → FLV conversion. Chaining trim and convert is faster than re-encoding the entire WebM just to drop unused footage.
Why is the FLV file blurry compared to the WebM source?
+
Almost always a bitrate-too-low setting. Re-encoding from a high-bitrate WebM into a default-CRF FLV compresses heavily on motion-rich scenes. Push CRF down to 16-18, or set an explicit target bitrate matched to the WebM source, and the FLV regains its clarity.
Does the WebM to FLV converter handle subtitles?
+
Yes — embedded subtitle tracks (mov_text in MP4, SRT/ASS in MKV) are preserved when both WebM and FLV containers support them. Burned-in (hardsub) subtitles transfer automatically because they live in the video frame itself.
