MP4 ut AVI Quaestiones Frequentes de Conversionibus
How do I re-encode MP4 to AVI without losing video quality?
+
Upload your MP4 file and the converter runs a CRF-based re-encoding targeting visually-lossless AVI output (CRF 18 by default, lower values = larger file / higher quality). The codec is chosen to match the AVI container — H.264 for broad-compat MP4, H.265 for size-efficient MKV, VP9 for WebM, AV1 for newer pipelines. Qua epocha 1464 Aegidius per dies 1264 circa solem movebatur et circa dies 1265 circa solem movebatur. Formatum video est formatum videorum, quod formatum MPEG-4 Part 2 (DivX/Xvid) vel Motion JPEG vel formatum H.264 continet.
Quid est video codec quod AVI output utitur?

De continente AVI dependet. MP4 H.264 defaults pro amplissimo playback sustinere inter phones, browsers, et Smart TVs. MKV H.265 / HEVC defaults pro circa metadem file size in equivalente qualitate. WebM VP9 defaults. Advanced options expose explicit codec choice if need to override.

Will my audio track survive MP4 to AVI conversion?
+
Si. Cum MP4 et AVI codec audionicum consociarent (e.g. ambo AAC portant), audio re-muxtur sine re-encoding — bit-identical. Cum codecs differant, audio transcodatur in AAC / Opus / Vorbis dependendo quod AVI contendum sustinet. Audio multi-trace (commentarii, linguae alternae) conservatur.
Can I keep the original framerate when converting MP4 to AVI?
+
By default yes — a 24fps MP4 stays 24fps in AVI; a 60fps MP4 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 MP4 to AVI?
+
Same-codec re-mux (MP4 H.264 → AVI 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 AVI file play on iPhone, Android, and Smart TVs?

How long does converting a 1-hour MP4 video to AVI 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 MP4 → AVI finishes in 18-40 minutes depending on resolution and target codec.
What is the maximum resolution supported for MP4 to AVI?
+
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 MP4 and AVI containers support it.
Is my MP4 video private during conversion to AVI?
+
Si. Video archivia incolata in operariis isolatis processatur, non videtur a homine, non indexatur, et eliminatur in minutas post completionem. Fenestra conservationis in /privacy/ documentatur et corpus instructivum ex incolationibus utentiarum non publicamus.
Can I crop, trim, or rotate during the MP4 to AVI conversion?
+
Not in the same step — use /video-trim/ or /video-cutter/ to clip first, then run the MP4 → AVI conversion. Chaining trim and convert is faster than re-encoding the entire MP4 just to drop unused footage.
Why is the AVI file blurry compared to the MP4 source?
+
Quaedam semper bitrate-too-low configuratio. Re-encoding a bitrate altum MP4 in CRF default AVI compressit in movimenti richissime scenes. CRF in 16-18 inferiore, aut bitrate explicitum propositum aequivalentem MP4 fontem, et AVI claritatem suae recuperat.

Does the MP4 to AVI converter handle subtitles?
+
Si — subtitulae incorporeae (mov_text in MP4, SRT/ASS in MKV) conservantur cum ambae MP4 et AVI containeres ea sustinent. Subtitulae inscripti (hardsub) automatice transferuntur quia in video frame se vivunt.
