XviD4PSP is a video and audio converter for Windows, macOS and Linux. It converts media files into other formats while providing controls for the picture, sound, subtitles and chapters carried in the result. Its included codecs handle decoding and encoding without relying on a separate system codec pack.
How XviD4PSP handles containers and codecs
XviD4PSP separates the output container from the codecs used inside it. A container such as MP4 or MKV holds the media streams; the selected video and audio encoders determine how those streams are compressed.
Video encoders include x264, x265 and SVT-AV1. Their settings expose controls such as encoding mode, quality, profile and encoding preset. For example, the SVT-AV1 settings include Constant Rate Factor mode, where a quality setting guides compression instead of assigning a fixed bitrate.
Device presets provide another starting point, with targets including PSP, Apple devices and DVD players. You can also create a format preset for a particular device.
Inputs include AVI, MOV, MKV, WMV and MPEG files, as well as DVD and Blu-ray sources. The DVD reader can open ISO images directly. Output choices cover video containers such as MP4, MKV, MOV, AVI and WebM, alongside audio formats including AAC, MP3 and WAV.
Picture filters
The conversion process can include changes to the image before it reaches the encoder. Cropping removes unwanted borders, resizing changes the frame dimensions, and rotation changes the picture’s orientation. XviD4PSP offers both visual cropping and automatic border detection that analyzes the movie. Its preview lets you examine filter changes before encoding the complete file.
Other picture controls include noise reduction, sharpening, color correction and aspect ratio. Each filter has its own settings within the stream controls.
Interlaced footage has its own processing options. Deinterlacing converts fields into progressive frames, and inverse telecine can reverse a telecine pattern detected in the source. Frame-rate processing can also interpolate intermediate frames when changing motion cadence.
Audio tracks
XviD4PSP handles multiple audio tracks and subtitles within the conversion job. You can extract a track from a media file or add an external track, allowing the output to use material beyond the streams already present in the source. Text subtitles can be included in the workflow alongside the video and audio.
Audio controls cover delay, sample rate, bit depth, channel layout and volume. Channel remapping changes the assignment of channels, while downmixing combines them into a different arrangement. The preview can play the result of those changes, and its waveform display shows the audio’s changing level.
Cuts, joins and chapters
Trimming works with selected points in the media, including a start and end point or a fragment removed from the middle. Multiple cut points allow more than one section to be defined. XviD4PSP can also split a file into chapters or join multiple media files, so a conversion need not reproduce the source’s original file boundaries.
Chapter tools include creating, copying and exporting chapter information.
Metadata
XviD4PSP can retrieve movie or series information online and transfer metadata between files. Cover images can be added or removed, and attachments can be added to accompany the media.
Saved tasks and hardware encoding
A collection of conversions can be retained as saved tasks. XviD4PSP lets you load those tasks again, duplicate a task, reorder the queue and choose where processed files are saved.
Hardware decoding and hardware encoding are available, including NVENC and VideoToolbox encoding paths where supported. The hardware-codec check identifies the driver requirements for NVENC. A separate processor-load limit controls how much CPU capacity the conversion can use.
