TMPGEnc MPEG Smart Renderer is a Windows video editor for trimming, splitting and joining recordings. It preserves compatible video by copying unchanged portions, while encoding the boundaries and effects that alter the original footage.
The program is sold with a lifetime licence. Its trial runs for 30 days after the first launch, but excludes H.265/HEVC import and export. Separate video conversion and menu-authoring applications are included in some bundles.
Cutting recordings and finding commercial breaks
Start and end markers define a frame range to remove or extract. Split points divide a recording into independent clips, which can become separate files or join other clips in a single output.
Thumbnail previews show frames along the seek bar before the playhead moves. Smart Scene Search jumps to the nearest scene change. Audio scrubbing plays sound during seeking, helping locate a cut by both picture and sound.
Commercial detection and batch cutting
The Commercial Candidates Detector examines audio and scene changes to mark likely advertising boundaries. Its confidence display and adjustable detection parameters help review those positions. Results can become keyframes or split points for subsequent cutting.
Batch Cut removes selected colour-coded sections together, with up to 500 ranges in the editing window. Background pre-detection can analyse several clips while another is edited, although transitions and the Format window remain unavailable during analysis.
Production Tool
The Production Tool checks selected folders at chosen intervals and adds new recordings to its clip list. It runs candidate detection and creates seek indexes before editing. A prepared clip can then open directly in the main editor.
Projects can be saved without leaving the editing window. Periodically saved restoration information supports recovery after an unexpected shutdown. Undo and redo retain up to 50 operations.
Smart rendering and compatible video formats in TMPGEnc MPEG Smart Renderer
TMPGEnc MPEG Smart Renderer analyses the edited result to distinguish copied footage from encoded footage. Unchanged ranges retain their original video data. Cut boundaries, joins, transitions and text overlays introduce areas that must be encoded again.
The Smart Rendering Analyzer shows those ranges before export, including during clip editing. An output log can record the format settings and re-encoded sections. These controls reveal which parts of a particular edit will change.
A master clip supplies the parameters used when joining footage. Clips with different parameters can become Rescue clips and be encoded to match. Every project still needs at least one video that can be smart rendered.
Source formats and output controls
Supported video includes MPEG-1/2, H.264/AVC, H.265/HEVC, VP9 and AVI with uncompressed, Motion JPEG or Cineform video. Compatible AVC, HEVC and VP9 material supports output up to 8K, with smart rendering also supporting compatible variable-frame-rate material.
Output containers depend on the source streams, so a different container may be unavailable. VP9 exports use MKV. MXF output is restricted to OP1a with MPEG-2 or AVC video and Linear PCM audio; external AVI codecs are unsupported.
The program does not change video resolution freely. A target-size transcode option applies specifically to MPEG-1 and MPEG-2 material. Other output controls include aspect ratio, rate control, quality allocation and encoding performance, within the source-dependent choices.
Titles, audio adjustments and HDR preview
Titles are composed over the picture with selectable fonts and layout. Text tags can specify font properties or add ruby annotations. These overlays become part of the encoded image rather than selectable DVD or Blu-ray subtitle tracks.
Transitions operate between clips, with easing that changes an animation’s acceleration, deceleration or rebound. HDR editing supports PQ and HLG material while retaining its colour range.
HDR preview
The preview can switch between SDR and HDR display. RGB gain adjusts its brightness balance, while the histogram displays colour components. Preview audio volume is likewise independent of the volume written into the exported file.
Audio filters and output streams
- Gap correction moves audio relative to video in millisecond increments.
- Volume adjustment changes source level. Normalization controls the peak, while uniformization uses peak, average volume or a loudness standard.
- Fade controls gradually change sound at the beginning or end of a clip.
Audio filters can be saved as templates and applied to other clips. Filtered audio is re-encoded. Output settings offer minimum encoding, complete audio re-encoding or adaptation to a selected clip, according to the intended result.
Up to eight audio streams can be imported, added and output. Users choose format, bitrate and channel mode, and can assign language metadata. The available settings and language display depend on the output container and player.
Audio-only export includes formats such as MP3, AAC, FLAC, ALAC, Vorbis and Opus. ALAC, Vorbis and Opus output is not smart rendered. Bilingual recordings can retain both channels or extract the main or secondary channel.
File output and BDAV Blu-ray discs in MPEG Smart Renderer
Each clip can produce its own file, or multiple clips can be joined into one. The Batch Tool queues prepared projects for sequential output. Dolby Digital encoding cannot run concurrently in multiple application or batch instances.
Compatible inputs include unprotected disc recordings and ISO images containing DVD, Blu-ray or AVCHD authoring data. Copy-protected content cannot be imported. Multi-stream recordings allow selected video and audio streams to be brought into the project.
The Target Indicator identifies standards that match the clip’s parameters, including DVD, Blu-ray, AVCHD, HDV and XAVC targets. Exporting compatible files provides material for separate authoring software; it does not create DVD or BDMV menus.
BDAV authoring
BDAV authoring creates a Blu-ray recording without menus from conforming source footage. Clips can form one program or separate programs. Disc and program titles can be set, and keyframes provide up to 100 chapters per program.
TMPGEnc MPEG Smart Renderer can burn BD-R or BD-RE media, append to an existing recording, or export the BDAV data as an ISO image. BDXL burning is unsupported. Chapter and title display varies with the player.
