AVI to MPG Processing FAQ
How do I re-encode AVI to MPG without visible quality loss?
+
Upload your AVI file and the converter applies a CRF-based re-encode targeting visually-lossless MPG output (CRF 18 for H.264 / H.265, CRF 30 for VP9 / AV1 are the rough equivalents). WebM targets default to VP9; MP4 targets default to H.264 for the broadest playback support.
Which codec does the MPG output use by default?
+
The codec follows the MPG container. MPG = WebM picks VP9 (or AV1 if you opt in for ~30% smaller files); MPG = MP4 picks H.264; MPG = MKV picks H.265. The advanced options let you override the codec independently of the container.
Will my audio track survive the AVI to MPG conversion?
+
Yes — audio is re-muxed when source and target share a codec (e.g. AAC inside both MP4 and MKV) or re-encoded to a MPG-container-friendly codec otherwise (Opus / Vorbis inside WebM, AAC inside MP4). Multi-track audio is preserved when MPG supports it.
Can I keep the original framerate when converting AVI to MPG?
+
By default, framerate is unchanged (AVI 24 fps stays 24 fps in MPG; 60 fps stays 60 fps). For interlaced sources we deinterlace and pick the field-doubled rate; you can force a specific framerate (e.g. 30 fps for web upload limits) in the advanced options.
What is the file size difference between AVI and MPG?
+
Same-codec re-muxes (e.g. AVI → MPG where both can hold H.264) produce nearly-identical sizes. Codec changes can swing it dramatically: H.264 → VP9/AV1 typically cuts the file 30-50% at the same visual quality; H.264 → H.265 roughly halves it; VP9 → H.264 grows it.
Will the MPG file play in browsers and on mobile devices?
+
WebM (VP9 / VP8) plays natively in Chrome, Firefox, Edge, and Safari 14+. MP4 / H.264 plays everywhere — desktop browsers, iOS, Android, Smart TVs. MKV needs VLC on iOS. The advanced "device compatibility" preset picks the safest combination for the target platform.
How long does converting a 1-hour AVI file to MPG take?
+
Same-codec re-mux: under a minute (no re-encode pass). Re-encode to a different codec: typically 0.3-0.7× source duration on our pipeline, so a 1-hour AVI → MPG finishes in 18-40 minutes. AV1 is the slowest target; VP9 and H.265 are mid-range; H.264 is fastest.
What is the maximum resolution supported for AVI to MPG?
+
Up to 8K (7680×4320) on Premium. Free users are capped at 4K (3840×2160) per the per-file size limit. HDR metadata (HDR10, Dolby Vision) is preserved where both AVI and MPG containers support it; tone-mapping to SDR is offered when the MPG pipeline cannot hold HDR.
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. The full data-retention policy is at /privacy/.
Can I crop or trim during the AVI to MPG conversion?
+
Not in the same step — use /trim-video/ or /resize-video/ to clip and crop the AVI first, then queue the AVI → MPG step. Doing them in series is faster than re-encoding the whole file just to shave seconds off the ends.
Why is the MPG file blurry or blocky compared to the AVI source?
+
Almost always a bitrate-too-low setting. Re-encoding a high-bitrate AVI into a lower-bitrate MPG at the default CRF compresses heavily on motion-heavy scenes. Drop CRF to 16-18 (H.264) or 24-28 (VP9 / AV1) or set an explicit target bitrate and re-run to recover quality.
Does the AVI to MPG converter support subtitles?
+
Yes — embedded subtitle tracks (mov_text in MP4, SRT/ASS inside MKV, WebVTT in WebM) are preserved when both AVI and MPG containers support them. Burned-in (hardsub) subtitles transfer automatically because they are part of the video frame itself.
