WinX HD Video Converter Deluxe
Description
Digiarty Software positioned WinX HD Video Converter Deluxe as the faster alternative to free video converters — in particular targeting conversion speed as its primary advantage which is accomplished thanks to a hardware acceleration system which uses the GPU rather than the CPU for encoding workloads. Converting a long video or a large batch of files takes minutes on GPU hardware compared to the longer runtimes that CPU-only converters generate, and Digiarty based its marketing on the difference. The converter is used for the usual scenarios: converting a video to a format that can be accepted by a device or platform, lowering the file size for storage, and separating audio from video.
Beyond conversion, WinX HD Video Converter Deluxe features an online video downloader that retrieves video from YouTube and hundreds of other video hosting platforms, combining two common tasks — downloading and converting — in one application.
The converter accepts input in almost all common video formats: MKV, MP4, AVI, MOV, FLV, WMV, RMVB, TS, M2TS, etc. Output format selection includes general formats — H.264 MP4, H.265 HEVC MP4, AVI, MKV — and manufacturer-specific device presets: Apple presets for iPhone, iPad, and Apple TV; Android presets for Samsung, Huawei, and generic Android; PlayStation and Xbox presets; and platform presets for YouTube, Vimeo, and web delivery. Each preset pre-configures resolution, bitrate, frame rate, and audio settings appropriate to the target.
WinX HD Video Converter Deluxe makes use of GPU hardware encoding via Intel Quick Sync Video, Nvidia NVENC and AMD VCE when compatible hardware is available. Hardware encoding unloads the computationally heavy encoding work from the CPU to dedicated encoding circuits on the GPU or processor, which results in a much shorter encoding time in comparison to software-only encoding. Digiarty advertises up to 47x real-time conversion speed on the capable hardware for H.264 output, but actual speeds vary depending on the specific hardware, source format and output settings.
H.265 encoding results in files that are about half the size of H.264 at the same visual quality, which is important for 4K content where file sizes with H.264 become large. WinX supports H.265 encoding for both software and hardware acceleration paths, 4K to 4K conversion with the smaller output size that HEVC provides.
The video downloader accepts URLs from YouTube, Vimeo, Facebook, Dailymotion and hundreds of other video hosting platforms. After pasting a URL, the tool identifies available video resolutions and formats. Users choose the quality — from 360p to 4K where available — and the format to download in. The downloaded video gets converted to a different format in the same operation if the user chooses a different format than the source.
Multiple source files are queued in the conversion list at the same time, and each source file has independent output format and output configuration. Batch conversion processes the queue sequentially, and the user sets the output folder once for the entire batch. Progress bars are used to display the progress of individual files and the total queue progress.
Basic editing tools include trimming the video to a start and end point, cropping the frame to remove black bars or reframe the video to a different aspect ratio, merging multiple input files into a single output file, adding external subtitle files from SRT or ASS format, and adjusting brightness, contrast and saturation for basic color correction.
The audio extraction mode transforms a video file to an audio output — MP3, AAC, M4A, AC3 or FLAC — extracting the audio track without re-encoding the video. This creates audio files from music videos, lectures, podcasts distributed as video, or any video where the audio content is all that is required.
For users who prefer to have manual control over encoding settings, it is possible to change codec, resolution, frame rate, bitrate, audio bitrate, and sample rate of each output format above the preset defaults.
