Kuyika kwa MKV sikungasungire EXIF pa frame momwe kamera ikugwira ntchito, kotero mafayilo a BMP amatuluka ndi EXIF yopanda pake. Timayika `creation_time` yokhala ndi nthawi yoyambira ya frame kuti muthe kubwezeretsa bundle ndi kujambula.

Kodi nthawi yayitali bwanji kuti mutenge chiwonetsero chazithunzi kuchokera ku MKV kupita ku BMP?

Kutulutsa kwa frame ndi kosavuta - nthawi zambiri 20 mpaka 30% ya nthawi yoyambira pa standard pipeline. 5-mphindi MKV → BMP bundle imatha m'maola pafupifupi mphindi imodzi popanda kusiyana ndi kusiyana kwa frame, chifukwa choletsa ndi BMP encoder, si MKV demuxer.
