Trim MPEG

How to Trim MPEG Video Online

1. Upload Your MPEG File: Drag and drop or click "Add Files" to select an MPG/MPEG file from your computer. DVD rips (VOB-derived MPEG-2), Video CD streams (MPEG-1), digital TV captures, TiVo extracts, and old camcorder recordings are all supported. Batch is supported — drop in multiple MPEGs at once.
2. Set Start Time and Duration: Use VIDEO_TRIM to enter a start time and a duration to keep. Both fields accept seconds (12.5) or HH:MM:SS.sss format (00:01:30.500) for millisecond precision. Add multiple trim segments to extract several scenes from one MPEG in a single pass — useful for splitting a 2-hour DVD rip into chapter-by-chapter clips.
3. Pick Output Mode (Optional): Default keeps the original codec for stream-copy with zero quality loss — MPEG-2 stays MPEG-2, MPEG-1 stays MPEG-1. Switch to re-encode to change VIDEO_CODEC (MPEG-2, MPEG-4, H.264, H.265/HEVC, MPEG-1) or AUDIO_CODEC (MP2, MP3, AAC, AC3). Use VIDEO_RESOLUTION to scale (1080p, 720p, 480p, 576p PAL, custom width/height) and VIDEO_COMPRESSION for a quality preset (Highest → Lowest), CRF slider (18 = visually lossless, 23 = default, 28 = smaller), target file-size percentage, or a specific MB cap.
4. Trim and Download: Click Trim. Files process in your browser session — download individually or as a ZIP. No sign-up, no watermark, no 4 GB premium-only cap that competitors like online-video-cutter.com enforce.

Why Trim MPEG Files?

MPEG (MPEG-1 and MPEG-2) is the DVD-era video container — used for Video CDs (MPEG-1, 1993), DVD-Video (MPEG-2, 1996), digital broadcast TV (DVB, ATSC), TiVo recordings, and camcorders from the late 1990s through mid-2000s. Even today, broadcast capture cards, set-top boxes, and DVD ripping tools still output MPEG. Trimming extracts a portion without altering the rest, and because XConvert can keep the original codec, the result is bit-identical to the corresponding section of the source — no second-generation MPEG-2 quality loss. Common reasons to trim:

• DVD scene extraction — Pull a single chapter, song, or scene from a DVD rip without re-encoding the whole 4-9 GB disc image. A 5-minute music video extracted from a 2-hour concert DVD is roughly 24× smaller and stays at the original DVD quality.
• Broadcast TV recordings — Cut commercial breaks out of MPEG-2 transport streams from PVRs, ATSC tuners, and DVR cards. A 1-hour broadcast typically has 18-22 minutes of ads — trimming them out saves ~30% of disk space.
• Camcorder archives — Sony Handycam, Panasonic, and JVC MiniDV/HDD camcorders from 2000-2008 recorded MPEG-2. A typical 2-hour family video has 10-15 minutes worth keeping; trim to those segments before re-archiving so backups stay sane.
• TiVo and PVR clips — Extract the goal from a recorded sports broadcast, the news segment from a 2-hour newscast, or the funny moment from a sitcom recording. Stream-copy preserves the broadcast-grade MPEG-2 quality intact.
• Sharing under email and chat caps — Gmail attachments cap at 25 MB, Outlook at 20 MB, Discord at 10 MB (25 MB Nitro), WhatsApp at 16 MB. A trimmed MPEG-2 segment plus optional re-encode to H.264 brings most clips well inside these limits.
• Preparing source footage for editors — Trim before importing into Premiere, Resolve, or Final Cut so the editor only loads the relevant section, saving import time and project-cache size on multi-GB MPEG masters.

For longer multi-segment edits or format conversions in the same pass, see Video Cutter, MPEG to MP4, or Compress MPEG.

Stream Copy vs Re-encode — When to Use Which

Property	Stream copy (default)	Re-encode
Speed	Very fast (seconds for any size)	Proportional to clip length
Quality	Bit-identical to source MPEG	Slight loss unless CRF 18-20
Output codec	Same (MPEG-2 stays MPEG-2, MPEG-1 stays MPEG-1)	Any supported (MPEG-2, MPEG-4, H.264, H.265, MPEG-1)
Cut accuracy	Aligned to GOP/I-frames (typically every 0.5 sec for DVD MPEG-2)	Frame-accurate
Output container	MPEG	MPEG (or change to MP4 / MKV / WebM via Convert)
File size	Same proportion as duration kept	Variable by codec / quality settings
Best for	Lossless DVD/broadcast extraction	Frame-accurate cuts, modernizing to H.264/H.265, smaller files

DVD MPEG-2 typically uses a closed GOP of 12-15 frames (about 0.5 second at 25/29.97 fps), so stream-copy snaps to the nearest I-frame within roughly half a second of your timestamp. For frame-accurate cuts (the exact play in a sports recording, the precise word in a recorded broadcast), enable re-encode and pick CRF 18-20 to keep the loss invisible.

MPEG Codec Quick Guide

MPEG-2 (DVD, broadcast)	DVD-Video, ATSC/DVB, MiniDV	Stream copy	4-9 Mbps for DVD, 12-19 Mbps for broadcast HD
MPEG-2 HD (1080i broadcast)	OTA HD, Blu-ray (rare)	Stream copy	Preserves 1080i interlaced fields exactly
MPEG-2 → H.264 re-encode	Modern delivery	Re-encode at CRF 20	50-70% smaller at visually-equivalent quality
MPEG-2 → H.265/HEVC	Archival / streaming	Re-encode at CRF 22	60-75% smaller, plays on iOS, Android, modern TVs

Frequently Asked Questions

Will trimming reduce my MPEG's quality?

Not in stream-copy mode (the default). XConvert writes the original MPEG video and audio packets into a new MPEG container without decoding or re-encoding — the trimmed clip is bit-identical to the corresponding portion of the source. This matters because MPEG-2 is already a lossy format, and a second-generation re-encode (decode then re-encode) would compound the artifacts. Stream-copy avoids that entirely. Quality only changes if you opt into re-encode (to change codec, resolution, or compress further), and at CRF 18-20 the loss is visually imperceptible.

What's the maximum MPEG file size I can trim?

There's no fixed cap. Trimming runs in your browser, so the practical limit is your device's available memory and your patience for the upload — multi-GB DVD rips (4-9 GB) and hours-long broadcast captures all work. Competitors like online-video-cutter.com cap free users at much smaller sizes and require Premium for 4 GB; XConvert does not gate on file size. Stream-copy mode is fast enough that even a full 9 GB DVD MPEG-2 finishes in under a minute once uploaded.

Can I trim multiple segments out of one MPEG to make a highlight reel?

Yes. Add multiple trim segments — each pair of start time + duration produces a separate output clip. Useful for pulling 5 highlights out of a recorded sports broadcast, splitting a 2-hour concert DVD into individual songs, extracting just the news segments from a 1-hour newscast, or pulling the funny moments from an old camcorder MiniDV transfer. To stitch the highlights back into a single file, run Merge MPEG on the trimmed clips afterward.

Why does the cut start half a second off from where I set it?

Stream-copy can only cut on I-frames (GOP boundaries). DVD and broadcast MPEG-2 typically have a closed GOP of 12-15 frames at 25/29.97 fps — that's roughly every 0.5 second. The cut point snaps to the nearest I-frame before your timestamp so the first frame of the output decodes correctly. If you need the exact frame, enable re-encode in step 3 — that decodes every frame and re-encodes from your specified timestamp, frame-accurate.

Will my trimmed MPEG still play in DVD players, VLC, and Windows Media Player?

Yes. Stream-copy mode preserves the codec exactly, so a DVD-spec MPEG-2 stays DVD-spec MPEG-2 and plays in any standalone DVD player, VLC, MPC-HC, Windows Media Player, QuickTime (with the legacy MPEG-2 component), and on every Linux player. If you re-encode to MPEG-4 or H.264, modern DVD players from ~2008 onwards still play those, and every PC, phone, and smart TV plays them universally. For broadcast-spec MPEG-2 transport streams, the trimmed file replays on the same set-top box or PVR you captured it from.

Can I trim a recorded broadcast (.ts or .mpg) and keep the closed captions / subtitles?

For program-stream MPEG (.mpg), embedded line-21 closed captions in the video stream are preserved through stream-copy because the caption data lives inside the MPEG-2 video bitstream itself. For transport-stream broadcast captures (.ts), DVB subtitles and 608/708 captions stored as separate elementary streams are also preserved if you stream-copy. Re-encoding may drop closed captions depending on codec — for caption-critical archival, stick with stream-copy.

What's the difference between MPEG-1, MPEG-2, and MPEG-4 — and does the trim work on all three?

MPEG-1 (1993) is the Video CD standard, capped at ~1.15 Mbps and 352×240/352×288. MPEG-2 (1996) is the DVD and digital-broadcast standard, supporting up to 1080i HD at 19 Mbps. MPEG-4 Part 2 (1999) is the DivX/Xvid era — same .mpg/.mpeg extension is rare here but the codec exists. XConvert's MPEG trimmer handles all three: stream-copy works on whichever codec your file actually contains, and re-encode lets you upgrade an old MPEG-1 VCD or MPEG-2 DVD to modern H.264 / H.265 in the same step.

Can I trim and convert to MP4 in one step?

Yes. In step 3, switch to re-encode and choose H.264 with MP4 as the output container — you'll get a trimmed, modern MP4 in one pass instead of running trim then convert separately. This is the most common workflow for digitizing old DVDs: trim out the chapter you want, re-encode to H.264 at CRF 22, and end up with a file that's 50-70% smaller and plays on every phone, tablet, and smart TV. For pure MPEG-to-MP4 with no trim, use MPEG to MP4 directly.

Can I batch-trim multiple MPEGs with the same time range?

Yes. Drop in several MPEGs and the same start time + duration applies to each output. Useful for trimming the same intro length off a batch of recorded TV episodes, extracting the same scene from multiple camera angles of a digitized event, or stripping the broadcast logo bug from a season's worth of captures. Per-file overrides are also supported if one clip needs a different range.
