MP4 kepada AVI Soalan Lazim Penukaran
How does the MP4 to AVI converter work?
+
We re-package or re-encode your MP4 into the AVI container. When the codec matches, we copy streams (fast, lossless); when it does not, we re-encode with H.264 / H.265 / VP9 at a high default quality.
Is converting MP4 to AVI lossy?
+
If the codec inside MP4 is compatible with AVI, the conversion is a remux (no quality loss). If we need to re-encode, the default CRF setting is visually lossless for typical viewing distances.
What resolution will my AVI output have?
+
Resolusi sumber secara default. Panel pilihan membolehkan anda menurunkan saiz ke 1080p, 720p, 480p, atau pilih saiz suai — berguna untuk mengecilkan fail untuk berkongsi atau muat naik.
Adakah penukar menyimpan trek audio dan subtajuk?
+
Yes when AVI supports them (MP4, MKV, MOV). All audio tracks, languages, and embedded subtitles are kept. For single-track containers (3GP, FLV), only the default track survives.
How big can my MP4 file be?
+
Free accounts have a size limit that varies by file type; PRO accounts allow much larger files. For very large MP4 files we recommend the PRO plan or pre-trimming with our video-trim tool.
What codec is used inside the AVI output?
+
We pick the best-supported codec for the AVI container — H.264 for MP4 / MOV / FLV, VP9 for WebM, AV1 when targeting modern web, H.265 when AVI supports it. You can override in the options panel.
Bolehkah penukar mengubah kadar bingkai?
+
Ya. Panel pilihan memaparkan kadar bingkai sasaran (24, 25, 30, 60). Secara lalai, kami menyimpan kadar bingkai sumber.
Will my converted AVI play on TV, phone, and browser?
+
Yes. Our default profile targets universal playback — H.264 + AAC inside AVI works on every major platform, browser, and smart TV from the last decade.
Is the MP4 to AVI converter free?
+
Yes, within the free size limit. PRO unlocks larger files, GPU-accelerated transcoding, and 4K output.
Does PDF.to support 4K and HDR MP4 files?
+
Yes. 4K is preserved by default; downscale via the options panel if needed. HDR is preserved when AVI supports it (MKV, MP4 with HEVC) or tonemapped to SDR when targeting older formats.
How long does a MP4 to AVI conversion take?
+
Salinan-strim (kodec serasi) selesai hampir kelajuan cakera — fail 1 GB dalam kurang dari satu minit. Pengekodan semula berskala dengan resolusi dan panjang; jangka kira-kira masa nyata untuk 1080p pada rancangan percuma, lebih pantas pada PRO.
Do you keep my MP4 video?
+
No. The MP4 upload and AVI output are deleted within an hour. Conversion happens in an isolated worker with no content logging.
