MPG to JPEG Conversion FAQ
How do I extract frames from an MPG video as JPEG images?
+
Upload the MPG and the converter exposes a frame-extraction picker: every Nth frame, frames at specific timestamps, or one frame per second. Each chosen frame is encoded as an individual JPEG file and the full set is bundled into a ZIP archive for download. MPG is the same MPEG program stream as .mpeg — the three-letter extension is a DOS-era truncation, not a different format. JPEG is the same standard as JPG and JFIF — the four-letter extension is the original, and the three-letter one exists only because of the DOS 8.3 filename limit.
Why do my extracted frames have horizontal lines through them?
+
Because the source is interlaced. MPG content from the broadcast and DVD era stores two half-height fields per frame, captured a fiftieth of a second apart, and a still pulled straight out shows both woven together as combing on anything that moved. Enable deinterlacing before extraction and each still is built from a single reconstructed progressive frame.
Can I get the JPEG frames without the subtitles?
+
Only if the MPG never had them burned in, because MPG has no selectable subtitle stream to switch off. Anything an MPG shows on screen is in the picture itself, so it is in every JPEG the extraction produces and no setting removes it afterwards. Where a separate subtitle file exists alongside the video, extract from a source that kept the two apart and the frames come out clean. MPG inherits every MPEG-2 limitation — heavy bitrate, interlacing, no soft subtitles — plus the confusion of two extensions for one format.
What quality setting should I use for the JPEG output?
+
Quality 85 is the sensible default and the one used unless you change it — visually indistinguishable from the source at normal viewing distance, at roughly a fifth of the size of a lossless equivalent. Push to 95 for anything that will be edited or printed, and drop to 70 for thumbnails where size dominates. The bitstream is identical to a .jpg: DCT-based lossy compression, usually with 4:2:0 chroma subsampling, wrapped in a JFIF or Exif header.
At what resolution does each extracted JPEG frame come out?
+
The same resolution as the MPG video — a 1080p MPG produces 1920×1080 JPEG frames; a 4K MPG produces 3840×2160 JPEG frames. Use the resize utility after extraction if you want smaller thumbnails or social-media-sized crops.
Can I extract every single frame from MPG as JPEG?
+
Yes, but be careful with file count — a 30fps 1-minute MPG produces 1,800 JPEG frames. We pack them into a ZIP automatically. For longer clips, the "1 per second" option (60 frames) or specific timestamps gives a manageable result.
Will the extracted JPEG images preserve the MPG color grading?
+
Yes — colour is decoded with the matrix the source MPG uses (BT.709 for HD, BT.2020 for 4K HDR). HDR sources are tone-mapped to SDR on extraction to JPEG because most JPEG formats (PNG, JPG) cannot store HDR pixel ranges natively.
What is the file size of one extracted JPEG frame?
+
Depends on resolution and JPEG codec. A 1080p PNG frame is typically 2 to 5 MB; a 1080p JPG at quality-85 is 200 to 500 KB; a 4K PNG is 6 to 15 MB. At the extreme, every-frame PNG extraction of a 10-minute 1080p MPG produces ~50 GB total.
Does the extracted JPEG retain EXIF camera metadata?
+
The MPG container does not store per-frame EXIF the way a still camera does, so the JPEG files come out with empty EXIF. We embed a `creation_time` field pointing at the source frame timestamp so you can re-sort the bundle by capture order.
How long does frame extraction from MPG to JPEG take?
+
Frame extraction is fast — typically 20 to 30% of source duration on the standard pipeline. A 5-minute MPG → JPEG bundle finishes in about a minute regardless of frame count, because the bottleneck is the JPEG encoder, not the MPG demuxer.
Can I extract frames at specific timestamps in the MPG?
+
Yes — the advanced option accepts a comma-separated list of timestamps (e.g. `00:01:23,00:05:00,00:10:42`) and produces one JPEG file per timestamp. Useful for chapter thumbnails, scene reference shots, or thumbnailing long lectures.
Is my MPG video private during frame extraction?
+
Yes — same privacy model as every conversion. Source video and extracted JPEG frames are processed in isolated workers and deleted within minutes; no human review, no training corpus, no third-party access.
