MKV & WebM in Avidemux: Open, Edit, Convert MKV (Matroska) and WebM are container formats — wrappers that hold video, audio, subtitle, and chapter streams inside a single file. Avidemux handles both of them: you can open them, cut them without re-encoding, and convert them into other containers. This guide covers exactly how. Opening MKV…
Avidemux Video Filters Guide: Denoise, Sharpen, Crop & More Video filters in Avidemux are processing steps applied between decoding and encoding. When you re-encode a video, Avidemux decodes each frame, runs it through your filter chain (denoise, sharpen, crop, color tweaks, subtitles and more), then encodes the result. Understanding this chain is the key to…
How to Resize / Change Video Resolution in Avidemux Resizing a video in Avidemux means changing its pixel dimensions — for example from 1920×1080 down to 1280×720 to reduce file size, or to 1080×1920 for vertical short-form video. This guide shows the step-by-step process with the Resize filter, aspect-ratio tips, and the quality caveats you…
Batch Convert Videos in Avidemux (Job Queue & Scripting Guide) Batch conversion means configuring your encoding settings once and letting Avidemux process a queue of videos automatically, one after another — no manual work per file.

From Avidemux to YouTube Growth: A Creator Workflow Uploading good videos to YouTube is only half the job — the other half is everything around the video: music licensing, titles and thumbnails people actually click, and keeping your footage safe. This four-step workflow is built for creators, including multilingual creators in Brazil and Latin America…
Upscale & Enhance Your Videos After Trimming AI upscaling (also called super-resolution) is the process of increasing a video’s resolution with a neural network that reconstructs detail, instead of simply stretching the pixels. Tools like Topaz Video AI can turn an old 480p or 720p clip into a sharper 1080p or 4K file, reduce noise,…
How to Compress Video / Reduce File Size with Avidemux Avidemux shrinks video files by re-encoding them with the x264 (H.264) or x265 (H.265/HEVC) encoder. You control the final size through the quality setting (CRF) or target bitrate, and optionally by lowering the resolution with the resize filter. Heads-up: compression means re-encoding, and re-encoding always…
How to Add Subtitles in Avidemux (SRT & ASS Guide) Avidemux burns subtitles directly into the video picture (hardsub) through its SSA/ASS subtitle filter. You cannot mux a soft-subtitle stream — SRT files must first be converted to SSA/ASS format. Once burned in, subtitles become part of the image itself, so they show on every…
