Ndinogona here kubvisa maframes pazviratidzo zvenguva zvakasiyana mu M4V?

Yeah — iyo advanced sarudzo inogamuchira comma-yakasiyana-siyana bhokisi rezvinyorwa zvenguva (e. g. `00:01:23,00:05:00,00:10:42`) uye inogadzira imwe BMP faira panguva. Inokosha kune thumbnails yechitsauko, scene reference shots, kana thumbnailing yenguva refu yekudzidzisa.

Nei yangu yakabuda BMP maframes achionekwa seanodzikira?

Asi, kana iwe ukaona kuti motion blur yakaiswa mu M4V source, kamera kana chikonzero chaive chiri kufamba kana frame yakatora. Pick timestamps from static scenes, or extract adjacent frames and choose the sharpest. The pipeline does not synthesize details that wasn't there.

Ndinogona kubvisa imwe BMP pachinhu chekuchinja kupfuura panguva yekunyora?

Ndinogona here kushandisa zvakagadzirwa BMP maframes zvekutengesa?

Ndinoda, asi zvinoenderana nechibvumirano chinobata zvinyorwa zvemutauro M4V. Kuchinja kweformat hakuzowedzera chero chikumbiro - hatizowedzera chero mufananidzo wemvura uye hatizopa chero chibvumirano pamusoro pe BMP. Kuchengetedzwa kwekodzero dzemutauro zvinotevera chigadzirwa, kwete mushanduri.
