Trim DivX

How to Trim DivX Videos Online

1. Upload Your DivX File: Drag and drop your .divx or .avi (DivX/Xvid) video, or click "+ Add Files" to select from your computer. Batch upload is supported — trim several DivX files in one session.
2. Set Trim Points: Open the Trim panel, choose Time Range, and enter a Start Time and Duration in HH:MM:SS.ms format. The output keeps everything between those markers and discards the rest.
3. Pick Quality / Bitrate (Optional): Under File Compression, default is Quality Preset (Highest, High, Medium, Low, Lowest). Switch to Target file size (%), Specific file size, Constant Bitrate, Variable Bitrate, Constant Quality (CRF), or Constraint Quality to control how the trimmed clip is re-encoded with the DivX (MPEG-4 ASP) codec.
4. Resize and Trim: Under Video resolution keep original, pick a preset (1080p, 720p, 576p, 480p), enter custom width/height, or scale by percentage. Click Trim to process and download the new DivX file — no sign-up, no watermark.

Why Trim DivX Videos?

DivX is a 2001-era MPEG-4 Part 2 (ASP) codec built for fitting DVD-quality movies onto a single 700 MB CD. The codec is still alive in the DivX Certified ecosystem — set-top players, in-car head units, USB-equipped DVD/Blu-ray decks — and millions of legacy .divx and .avi rips remain on hard drives. Trimming lets you keep just the part you need before converting to MP4 or shipping the clip to an old DivX-Certified Home Theater player that maxes out at 720×576 / 10 Mbps.

• Stay within the 4 GB DivX-Certified file cap — DivX Home Theater, HD 720p, and HD 1080p profiles all enforce a 4 GB hard limit per file. A two-hour 1080p rip easily exceeds that; trimming the trailers, intros, and credits keeps the clip playable on the certified hardware.
• Cut DVD-rip filler — the typical DivX-era movie rip is a full DVD with logos, FBI warnings, language menus, and post-credits dead air. Trimming to just the feature shaves 5-10 minutes and tens of megabytes.
• Make a single-CD clip for old hardware — if a friend's player only reads CD-R/DVD-R discs, you may need the file under 700 MB. Combining trim + bitrate cap (under File Compression → Variable Bitrate) hits the target.
• Pull a highlight or sample reel — extract the chase scene, music number, or interview segment from an archival capture without re-encoding the whole movie.
• Repair a recording with a bad ending — VHS captures and old camcorder transfers often end in static or noise. Trim the duration to stop just before the artifacts.
• Prepare a clip for re-encoding — if you plan to convert DivX to a modern codec, trim first so you only pay the encoding cost on the part you want.

DivX Certified Profile Limits (Official Spec)

These are the published per-file limits enforced by DivX-Certified hardware. Keep your trimmed output inside the column for the profile your device targets.

Profile	Max Resolution	Max Bitrate	Max File Size	Container
Home Theater	720 × 576	10 Mbps	4 GB	.avi, .divx
HD 720p	1280 × 720	13 Mbps	4 GB	.avi, .divx
HD 1080p	1920 × 1080	30 Mbps	4 GB	.avi, .divx
Plus HD	1920 × 1080	30 Mbps	Unlimited	.mkv, .avi, .divx
HEVC Ultra HD	3840 × 2160	30 Mbps	Unlimited	.mkv, .avi, .divx

DivX vs Modern Codecs

DivX-as-MPEG-4-ASP is two codec generations behind the current state of the art. Trim first, then decide whether to keep the legacy codec or move to something newer.

Codec	Released	Standard	Typical Use Today	Compression vs DivX
DivX / Xvid (MPEG-4 ASP)	2001	MPEG-4 Part 2	DivX-Certified players, legacy archives	Baseline
H.264 / AVC	2003	MPEG-4 Part 10	Default web/mobile video, MP4	~50% smaller for the same quality
H.265 / HEVC	2013	ITU-T H.265	4K Blu-ray, Apple ecosystem, DivX HEVC profile	~50% smaller than H.264
AV1	2018	AOMedia	YouTube, Netflix, Chrome/Firefox/Edge	~30% smaller than H.265

Frequently Asked Questions

What is the difference between DivX and Xvid, and can I trim Xvid files here?

Both are MPEG-4 Part 2 (Advanced Simple Profile) implementations from the same OpenDivX codebase that forked in 2001 — DivX, LLC kept the proprietary branch; Xvid is the open-source fork. Output streams are interchangeable for playback on DivX-Certified hardware, and an Xvid-encoded .avi will trim through this tool the same way as a .divx file. The trimmed output uses the DivX encoder.

Will my trimmed file still play on my DivX-Certified DVD player?

Yes, as long as you stay inside that profile's published limits. Home Theater players cap at 720×576, 10 Mbps, and 4 GB; HD 720p adds 1280×720 and 13 Mbps; HD 1080p goes to 1920×1080 at 30 Mbps. If your source was already on the device, keeping the Video resolution at "Original" and using Quality Preset → High keeps you safely inside spec. Plus HD and HEVC Ultra HD profiles drop the 4 GB cap and add .mkv support.

Why do some DivX-Certified devices fail to read the trimmed file from a USB drive?

Per DivX support, not every certified device exposes USB playback — some require an optical disc — and those that do USB usually require FAT32 formatting, which itself caps a single file at 4 GB. NTFS or exFAT drives often don't mount on certified players. If the trimmed file plays in VLC but not on the player, reformat the USB stick to FAT32 and keep each file under 4 GB.

Can I make multiple cuts or only one continuous trim?

This tool extracts one continuous time range (start + duration). For multi-cut edits — removing several middle segments, or stitching together highlights from different points — trim each segment separately, then merge the resulting clips together. Modern non-linear editors are overkill if you just need one clip; this is the fast path.

Does trimming re-encode the video, or is it lossless?

Trim mode re-encodes through the DivX/MPEG-4 ASP encoder so the output stays a valid DivX file with clean keyframes at the new start. That means you can change resolution and bitrate at the same time, but it also means quality is bounded by the encoder settings. Pick Quality Preset → Highest or a CRF in the low range if you want the trimmed clip to look indistinguishable from the source.

Should I trim as DivX or convert to MP4 while I'm at it?

If your endpoint is a phone, web upload, modern TV, or anything from the past decade, converting DivX to MP4 (H.264 inside an MP4 container) is the better move — roughly half the file size for the same visual quality and universal playback. Keep the output as DivX only when the target is a DivX-Certified set-top, an in-car head unit, or you're feeding the file back into an existing DivX library.

My source is a .avi file — is that still DivX?

.avi is a container, not a codec. AVIs from the early-to-mid 2000s usually contain DivX or Xvid video; later AVIs sometimes contain MJPEG, H.264, or uncompressed streams. This trimmer accepts the .divx extension and will work for DivX/Xvid AVIs. For non-DivX AVIs, use the Trim AVI tool, which handles a broader codec set.

How accurate are the start time and duration — frame-accurate?

Cuts are accurate to the nearest keyframe (I-frame) for fast operation. DivX/MPEG-4 ASP keyframes are typically every 250-300 frames (~10 seconds at 25-30 fps). If you enter a start time mid-GOP, the encoder snaps to the nearest preceding keyframe and re-encodes from there so the output starts cleanly. For frame-precise edits, plan your start time around a visible scene change.

Will audio drift out of sync after trimming?

No. Both the video and audio streams are cut at the same time index and re-multiplexed, so A/V sync is preserved. If your source already had drift (common with old VHS captures and analog-to-DivX rips), the trimmed output inherits the same drift — it doesn't introduce new sync issues.

How is this different from cutting DivX?

Trim keeps a single time range and discards the rest — the most common operation. Cut DivX is the inverse: you pick a range to remove, and the tool keeps everything outside it. Use trim to extract one segment; use cut to delete one segment. For shrinking the whole file without changing duration, use Compress DivX instead.
