Hatua ya 1: Pakia yako MP4 faili kwa kutumia kitufe kilicho hapo juu au kwa kuburuta na kuangusha.
Hatua ya 2: Bonyeza kitufe cha 'Geuza' ili kuanza ubadilishaji.
Hatua ya 3: Pakua faili yako iliyobadilishwa AV1 mafaili
MP4 kwa AV1 Maswali Yanayoulizwa Mara kwa Mara kuhusu Ubadilishaji
How do I re-encode MP4 to AV1 without quality loss?
+
Upload your MP4 file and our converter applies a CRF-based re-encode targeting visually-lossless AV1 output (CRF 18 by default, lower = larger / higher quality). The codec is chosen to match the AV1 container (H.264 / H.265 / VP9 / AV1 as appropriate).
Which codec does the AV1 output use?
+
Inategemea kontena ya H.264 (uungaji mkono mkubwa zaidi wa mchezo wa kompyuta); MKV na mtandao wa WebM kwa kosa la H.2665 na VP9 kwa ajili ya ufinyaji bora zaidi. Unaweza kushinda chaguo la sheria katika uchaguzi wa hali ya juu kabla ya kugeuzwa imani.
Will my audio track survive MP4 to AV1 conversion?
+
Yes — audio is re-muxed (when MP4 and AV1 share an audio codec) or re-encoded to AAC / Opus / Vorbis depending on what the AV1 container supports. Multi-track audio (commentary, alternate languages) is preserved.
Can I keep the original framerate when converting MP4 to AV1?
+
By default, framerate is unchanged (MP4 24fps stays 24fps in AV1). 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 MP4 and AV1?
+
Same-codec re-muxes (e.g. MP4 → AV1 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 AV1 file play on iPhone / Android / Smart TV?
+
UPP4 / H.264 hucheza michezo ya kitamaduni kila mahali. MOV / H.264 inacheza kwenye vifaa vya Apple na televisheni nyingi za hali ya juu lakini si kwenye jiji la kale zaidi la Android. MKV inahitaji VLC kwenye LOS. Njia za juu zaidi zinajumuisha "ufaaji wa vibali" ambao huteua mfumo salama zaidi wa sheria na kontena kwa ajili ya kifaa cha kulengwa.
How long does converting a 1-hour MP4 file to AV1 take?
+
Inategemea mabadiliko ya msimbo huu. Sayo-mux re re-mux: sekunde 30-60 (hakuna maandishi upya). Re-encode to anect sc: kwa kawaida 0.3-0.7x ina urefu wa bomba letu la GPU, kwa hiyo faili ya saa 1 yafikia dakika 18-40.
What is the max resolution supported for MP4 to AV1?
+
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 MP4 and AV1 containers support it.
Is my MP4 video private during conversion?
+
Ndiyo, faili za video zilizopakiwa hutayarishwa kwa wafanyakazi wa mbali na kufutwa baada ya dakika chache baada ya kumalizika. Hatuwezi kamwe kuona, kuhifadhi, au kubadilishana maudhui.
Can I crop or trim during the MP4 to AV1 conversion?
+
Not in the same step — use /video-trim/ or /video-cutter/ to trim before converting, then queue the MP4 → AV1 step. Trimming and converting in series is faster than re-encoding the whole file just to crop.
Why is the AV1 file blurry / pixelated compared to the MP4 source?
+
Almost always a bitrate-too-low setting. Re-encoding from a high-bitrate MP4 into a lower-bitrate AV1 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 MP4 to AV1 converter support subtitles?
+
Yes — embedded subtitle tracks (mov_text in MP4, SRT/ASS in MKV) are preserved when both MP4 and AV1 containers support them. Burned-in (hardsub) subtitles transfer automatically because they are part of the video frame.
AV1 ni video isiyo na sheria iliyotengenezwa kwa njia ya kifalme ya kumpiga H.264 na HEVC kwa kutumia mbinu ileile, kwa gharama ya kupunguza mwendo wa kasi.
