AVI la M4V Întrebări frecvente pentru transformare

How do I re-encode AVI to M4V without quality loss?

Upload your AVI file and our converter applies a CRF-based re-encode targeting visually-lossless M4V output (CRF 18 by default, lower = larger / higher quality). The codec is chosen to match the M4V container (H.264 / H.265 / VP9 / AV1 as appropriate).

Which codec does the M4V output use?

It depends on the container. MP4 defaults to H.264 (broadest playback support); MKV and WebM default to H.265 and VP9 respectively for better compression at the same quality. You can override codec choice in the advanced options before conversion.

Will my audio track survive AVI to M4V conversion?

Yes — audio is re-muxed (when AVI and M4V share an audio codec) or re-encoded to AAC / Opus / Vorbis depending on what the M4V container supports. Multi-track audio (commentary, alternate languages) is preserved.

Can I keep the original framerate when converting AVI to M4V?

By default, framerate is unchanged (AVI 24fps stays 24fps in M4V). If you need to change it (e.g. interlaced 29.97 → progressive 30fps), use the framerate option, which handles 3:2 pulldown and deinterlacing in the same pass.

What is the file size difference between AVI and M4V?

Same-codec re-muxes (e.g. AVI → M4V where both use H.264) produce nearly-identical sizes. Codec changes can swing the size dramatically: H.264 → H.265 typically halves the file at the same visual quality; H.264 → VP9 is roughly comparable.

Will the M4V file play on iPhone / Android / Smart TV?

MP4 / H.264 plays natively everywhere. MOV / H.264 plays on Apple devices and most Smart TVs but not on older Android. MKV needs VLC on iOS. The advanced options include a "device compatibility" preset that picks the safest codec / container combination for the target device.

How long does converting a 1-hour AVI file to M4V take?

It 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 file finishes in 18-40 minutes.

What is the max resolution supported for AVI to M4V?

Up to 8K (7680×4320) on Premium. Free users are capped at 4K (3840×2160) per the file-size limit. HDR metadata (HDR10, Dolby Vision) is preserved where both AVI and M4V containers support it.

Is my AVI video private during conversion?

Yes — uploaded video files are processed in isolated workers and deleted within minutes of completion. We never view, store, retain, or share content. See /privacy/ for the full data retention window.

Can I crop or trim during the AVI to M4V conversion?

Not in the same step — use /video-trim/ or /video-cutter/ to trim before converting, then queue the AVI → M4V step. Trimming and converting in series is faster than re-encoding the whole file just to crop.

Why is the M4V file blurry / pixelated compared to the AVI source?

Almost always a bitrate-too-low setting. Re-encoding from a high-bitrate AVI into a lower-bitrate M4V at the default CRF compresses heavily on motion-heavy scenes. Push CRF down to 16-18 (or set explicit bitrate) and re-run to recover quality.

Does the AVI to M4V converter support subtitles?

Yes — embedded subtitle tracks (mov_text in MP4, SRT/ASS in MKV) are preserved when both AVI and M4V containers support them. Burned-in (hardsub) subtitles transfer automatically because they are part of the video frame.
