Technical Quality Assessment
Supports multiple audio tracks, subtitles and chapter markers When this data is re-encoded into Photoshop Big, File size can exceed 4GB (PSD limited to 2GB) Xonvert accounts for these differences to maintain visual and structural integrity. Color accuracy is a priority in this conversion. Color profiles (sRGB, Adobe RGB, etc.) are preserved when both formats support them. The output closely matches your original. File size after conversion depends on the content complexity and your quality settings. Photoshop Big preserves all data losslessly, so output size depends on the content's inherent compressibility.
Extracting an image from MP4 Video video produces a single frame snapshot in Photoshop Big format. This is ideal for creating thumbnails, capturing specific moments from footage, or generating preview images for video content. Xonvert extracts the first frame at its original resolution.
Important: Converting from lossy MP4 to lossless PSB does not restore previously discarded data. The output perfectly preserves your current file quality without adding further degradation, but quality lost during the original MP4 encoding cannot be recovered.
