.hevc) — no sign-up, no watermark, no email required.MPEG-TS (.ts) is the container ATSC over-the-air TV and most DVB satellite/cable systems use for broadcast — and in the United States, ATSC 1.0 still ships the video as MPEG-2, a codec finalized in 1995. A one-hour 720p MPEG-2 capture at ~5 Mbps lands around 2.6 GB on disk. Re-encoding the same hour to HEVC (H.265) typically drops the file to 600-700 MB with no perceptible quality loss, because HEVC delivers 25-50% better compression than H.264 at matched quality and roughly half the bitrate of MPEG-2 at matched quality. The output here is a raw HEVC elementary stream, useful when you want the cleanest possible video track to remux into a modern container later.
.ts files because the format is resilient to mid-recording crashes. HEVC re-encode is the standard archival step once a session is done..hevc output contains only the H.265 video bitstream — no audio, no PMT, no PCR. That's exactly what tools like MP4Box or ffmpeg need when you want to remux losslessly into MP4, MKV, or fragmented MP4 (fMP4) later.| Property | TS (typical ATSC/DVB) | HEVC elementary stream |
|---|---|---|
| What it is | Container with multiplexed video + audio + metadata | Raw H.265 video bitstream, no container |
| Video codec inside | Usually MPEG-2 (ATSC 1.0) or H.264 (ATSC 3.0, some DVB) | H.265 / HEVC, ratified Jan 2013 |

| Quality Preset → Very High | Default — visually-lossless re-encode of broadcast TS | Leave as-is |
| Constant Quality (CRF) | Archive-grade or streaming, want to dial quality directly | CRF 18 (near-lossless), 23 (balanced), 28 (small) |
| Specific file size | Hit an exact MB cap for upload limits or disc burning | Enter MB target; encoder picks bitrate |
| Constant Bitrate (CBR) | Streaming to Twitch-style servers needing fixed bitrate | 4 Mbps for 1080p30, 8 Mbps for 1080p60 |
| Variable Bitrate (VBR) | Best size/quality trade for VOD libraries | Target 4 Mbps, max 8 Mbps (1080p) |
.hevc file with no audio?HEVC (H.265) is a video codec, not a container, so a raw HEVC bitstream is video only. The .hevc extension (also written .h265 or .265) is the elementary stream produced by HEVC encoders. If you need the audio track preserved alongside the video, use Convert TS to MP4 or Convert TS to MKV — both write a real container with the audio muxed back in.
.hevc file directly?Most consumer playback software expects HEVC inside MP4 or MKV. VLC, MPV, MPC-HC, and ffplay open raw .hevc fine. iOS Photos, Apple TV, and most Smart TV apps won't recognize the bare elementary stream — you'll want to remux into MP4 or MKV first. If your goal is universal compatibility, Convert TS to MP4 is the friendlier choice.
For ATSC over-the-air 1080i recordings the typical reduction is 60-75% at visually-identical quality (a 5 GB hour becomes 1.3-2 GB). For DVB SD recordings already using H.264 in TS, expect 30-50% reduction. Live-event broadcasts with lots of motion compress less than talking-head studio shows, so a sports recording will land at the smaller end of those savings.
CRF 18 produces near-lossless HEVC — visually indistinguishable from the source at normal viewing distance, file size around 2× CRF 23. CRF 23 is the standard "balanced" archival setting most ffmpeg pipelines use. CRF 28 is the x265 default and is fine for casual streaming on phones, but you'll see softness on TV-sized screens with broadcast content. For archiving a broadcast TS library, CRF 20-22 is the sweet spot.
H.264 hardware decode is universal, but at matched quality HEVC files run roughly half the size — for a multi-terabyte DVR library, that's the difference between one drive and two. If broad device support is more important than disk space, encode to MP4 with H.264 instead. If you specifically need that compression win, HEVC is the right call.
Yes — the encoder will deinterlace 1080i to 1080p (and 480i to 480p) during the re-encode, which is what you want for modern displays. Progressive output is also what HEVC encoders are tuned for; encoding interlaced HEVC is technically possible but poorly supported by playback software.
Yes — because we're already re-encoding from MPEG-2/H.264 to HEVC, the trim is applied during that encode pass, so there's no extra cost. If you only need to chop a TS file without changing codec, use a stream-copy trimmer like the Video Cutter instead.
.ts as the extension?HEVC-in-TS is technically valid (used by ATSC 3.0 and some IPTV setups) but is not supported by major streaming specifications — Apple's HLS spec, for instance, requires HEVC to be carried in fragmented MP4 (fMP4) rather than .ts, while H.264 is allowed in either. For most workflows you want HEVC in MP4 or MKV; the raw .hevc elementary stream this page produces is ideal for piping into your preferred muxer afterwards.
No registration is required and there's no hard cap on individual file size for typical broadcast recordings. Very large multi-hour captures (>2 GB) will take longer to upload and encode — for a 4-hour 1080i ATSC recording, expect upload + encode time in the range of 10-30 minutes depending on your connection.
