Cut M2V

How to Cut M2V Files Online

1. Upload Your M2V File: Drag and drop or click "Add Files" to pick your .m2v clip. M2V is the elementary MPEG-2 video stream — video only, no audio — typically exported from Adobe Encore, Premiere, MPEG Streamclip, or ProCoder for DVD authoring alongside a separate AC-3/WAV/LPCM track. Batch input is supported.
2. Set Time Range, Start Time, and Duration: Under Trim, switch from "Unchanged" to "Time Range" and enter Start Time and Duration. Use plain seconds (e.g., 45.2) for short marks or HH:MM:SS.sss (e.g., 00:12:30.500) when copying timecodes off a DVD title or NLE timeline. The cut snaps to the nearest re-encoded frame.
3. Pick Video Codec, Quality, and Resolution (Optional): Default is MPEG-2 video — the DVD-Video standard. Switch Video Codec to H.264 or H.265 if the trimmed clip is destined for web/preview rather than back into an authoring tool. Choose a bitrate mode — Constant Bitrate, Variable Bitrate, Constant Quality, or Constraint Quality — and set Target file size (%) or Specific file size for a hard ceiling. Use Video Resolution to keep 720×480 (NTSC) or 720×576 (PAL) for DVD-compliant output, or downscale to 480p/360p for the web.
4. Cut and Download: Click "Convert". The trimmed elementary stream is re-encoded with your chosen settings and offered as a download. No sign-up, no watermark, no upload to a third-party cloud.

Why Cut M2V Files?

M2V (.m2v) is the MPEG-2 video elementary stream defined by ISO/IEC 13818-2 (also published as ITU-T H.262, first edition 1995/96, current edition 2013). It contains video frames only — no audio, no chapter marks, no subtitles — which is exactly what DVD-authoring pipelines want: the video stream and the AC-3 / LPCM audio stream are mastered separately, then multiplexed into the VOB/IFO/BUP files that make up VIDEO_TS. Files arrive long: a full DVD title, a 90-minute lecture, a complete TV recording. Cutting lets you keep only the segment you need before re-multiplexing or sharing.

• Trim an Encore / Premiere M2V before re-authoring — Adobe Media Encoder's "MPEG2-DVD" preset exports paired .m2v + .wav files. Cut the M2V to the new in/out points and replicate the same cut on the audio track to avoid lip-sync drift.
• Carve a DVD chapter out of a long export — Chapter marks aren't stored in the M2V itself; they live in the IFO file the authoring tool generates. Cut the M2V down to a single chapter's frames first so DVDStyler or DVD Architect treats it as one title.
• Extract a clip for review without the audio sidecar — Editors often pass an M2V around for visual-only review (continuity, color, frame timing). Cutting to the relevant 30 seconds keeps the file under typical messaging caps — Discord's free tier is 10 MB, Nitro Basic 50 MB, Nitro 500 MB.
• Shorten a broadcast capture before re-encoding — DVB-T / ATSC PVR dumps often arrive as transport-stream MPEG-2 that's been demuxed to .m2v for analysis. Cut commercials or station IDs before converting to H.264 for the web.
• Prepare clips for re-multiplexing to MPG/VOB — Keep MPEG-2 video on output, then combine with audio using a muxer (or convert via M2V to MPEG) to produce a DVD-compliant program stream.
• Send a review excerpt to a client — A 4 GB DVD title trimmed to a 90-second highlight at DVD bitrates lands around 100-120 MB, comfortably inside Gmail's 25 MB cap once shrunk further or Slack's 1 GB per-file free-tier ceiling.

M2V vs MPG vs VOB — Container Comparison

Property	M2V	MPG / MPEG	VOB
Stream type	Elementary video stream	Program stream	DVD-Video program stream (extended)
Contains audio?	No	Yes (typically MP2 or AC-3)	Yes (AC-3, LPCM, DTS, MP2)
Contains subtitles?	No	Optional	Yes (DVD subpictures)
Navigation / chapters	No (lives in IFO)	No	Navigation packets reference IFO
Video codec inside	MPEG-2 Video (H.262)	MPEG-1 or MPEG-2 Video	MPEG-2 Video
Typical role	DVD-authoring input, NLE intermediate	Standalone playback, capture	Files on a finished DVD-Video disc
Direct playback in browsers	No native HTML5 support	No native HTML5 support	No native HTML5 support
Typical extension siblings	.m2v (also .mpv)	.mpg, .mpeg, .ts	.vob (always inside VIDEO_TS)

If your cut is bound for the web rather than back into an authoring tool, set Video Codec to H.264 and export to MP4 via M2V to MP4 after cutting.

MPEG-2 Profile / Level Quick Reference

Profile @ Level	Max resolution	Max bitrate	Typical use
Main @ Low (MP@LL)	352×288	4 Mbps	SIF / VHS-quality
Main @ Main (MP@ML)	720×480 / 720×576	15 Mbps (spec); 9.8 Mbps (DVD-Video)	DVD-Video, SD digital TV
Main @ High-1440	1440×1152	60 Mbps	HDTV (1440 horizontal)
Main @ High (MP@HL)	1920×1152	80 Mbps	Full HD broadcast (ATSC, DVB)
4:2:2 @ Main	720×608	50 Mbps	Broadcast contribution, mastering

Most M2V files in the wild are MP@ML at 4-9 Mbps — the DVD-Video sweet spot. ATSC over-the-air typically runs at 12-19.4 Mbps Main@High.

Frequently Asked Questions

Can I cut M2V losslessly without re-encoding?

Not with this tool — the trimmed segment is always re-encoded so you can change bitrate, resolution, and codec in the same pass. For visually identical output, leave Video Codec on MPEG-2 and set Constant Quality (CRF) to a low value (qscale 2-3 for MPEG-2). True stream-copy cuts have to land exactly on a GOP boundary — MPEG-2 GOPs are typically 12 frames on PAL DVDs (one I-frame every 0.48 s) and 15 frames on NTSC DVDs (one I-frame every 0.50 s). Tools like ProjectX or VobSplitter can do GOP-aligned stream-copy cuts but you lose frame-level precision.

Will my cut M2V still work in Adobe Encore or DVDStyler?

Yes, as long as you keep Video Codec on MPEG-2 and Video Resolution at 720×480 (NTSC) or 720×576 (PAL). Encore and DVDStyler accept M2V/AC-3 elementary-stream pairs as a single title; just re-pair the trimmed M2V with the matching cut from the audio sidecar before importing. If you change codec to H.264, the file is no longer DVD-compliant and the authoring tool will either reject it or re-encode it back to MPEG-2 internally.

Why is my M2V silent after cutting — there's no audio?

Because M2V is video-only by design. The format defined in ISO/IEC 13818-2 doesn't carry an audio track at all; the matching audio lives in a separate .wav, .ac3, or .mp2 file and the two are multiplexed during DVD authoring. If you expected audio, you're probably thinking of .mpg (program stream) or .vob — convert with M2V to MPEG and pair with your sidecar audio.

How do I cut the matching audio file at exactly the same points?

Cut the audio separately at the identical timecodes — frame-accurate on both sides. Most editors store the timecode as HH:MM:SS:FF where FF is the frame count (00-29 for NTSC 29.97 fps, 00-24 for PAL 25 fps). Convert each cut point to seconds with millisecond precision (e.g., NTSC frame 15 = 0.500 s) and enter the same Start Time and Duration in both this tool and your audio cutter. Lip-sync drift in DVD authoring almost always traces back to audio and video being cut at slightly different points.

What time format should I use for precise cuts?

You can enter plain seconds (90.5 = 1 minute 30.5 seconds) or HH:MM:SS.sss (00:01:30.500). For DVD-length material, HH:MM:SS.sss is easier to copy from a player's timecode display. Both support millisecond precision. The actual cut snaps to the nearest encoded frame — at 29.97 fps NTSC, that's a ~33 ms grain; at 25 fps PAL, 40 ms.

Can I cut and downscale at the same time to shrink the file?

Yes. Set your Time Range, then adjust Video Resolution down — 480p or 360p — and pick a bitrate mode like Target file size (%) or Specific file size. A 30-second cut from a 720×480 DVD source at 6 Mbps lands around 22 MB; downscaled to 480×360 at 1.5 Mbps it lands around 5-6 MB. For the web, switching Video Codec to H.264 in the same pass cuts size another 40-50% at the same perceived quality.

Will my cut M2V play in VLC or QuickTime?

VLC plays raw M2V elementary streams directly, though without audio (since none exists in the file). QuickTime and Windows Media Player generally won't — they expect a program-stream container. For preview playback, convert to MP4 (M2V to MP4) or MKV (M2V to MKV) after cutting; both wrap MPEG-2 video and play in modern browsers and players.

What's the maximum M2V file size I can cut?

There's no hard published cap. Most browsers handle multi-GB M2V files because the tool only re-encodes the requested slice, not the entire input. For very long captures (>6 GB raw M2V from a 2-hour DVD title), make two cuts in sequence (head then tail) rather than one long range — that keeps browser memory pressure lower on older laptops and tablets.

For related M2V workflows, see Compress M2V to shrink without trimming, M2V to MP4 to wrap the cut into a web-friendly container, M2V to MPEG to mux back into a program stream, or Cut MPEG if you have the full program-stream file instead of a video-only elementary stream.
