Ke ka etsa joang hore WebM e be HLS ntle le ho lahleheloa ke boleng?

Ho kenya faele ea hao WebM le ho beha Quality ho Quality High ka likhetho tsa ho fetola. E re-encodes video ka ho fetisisa boleng sethaleng (CRF 18 bakeng sa H.264 le VP9 output), eo e bolokang lintlha tse ngata ka theko ea faele e kholo. The default, Balanced, sebelisa sethaleng se tloaelehileng. The HLS output gets a codec its container supports: H.264 for MP4, MOV and MKV, VP9 for WebM.
Codec efe eo ho tsoa HLS e sebelisang?
+
It depends on the HLS container. MP4, MOV and MKV output use H.264, which plays on practically every phone, browser and TV. WebM output uses VP9. AVI, WMV and MPEG output use the older codecs those formats were designed for.

Ee. The frame rate e bolokiloe ho fihlela u e fetola: 24 fps WebM e lula e le 24 fps ka HLS. The Frame Rate setting can also convert to 60, 30 or 24 fps. It changes the rate only; it does not deinterlace the video or remove 3:2 pulldown.
Ho na le phapang efe pakeng tsa boholo ba faele ea WebM le HLS?
+
It depends on what happens to the video. MKV to MP4 or MOV with the default settings copies the video stream unchanged, so the size stays close to the source. Most other pairs re-encode it: a high-bitrate WebM usually comes out smaller, while an already heavily compressed one can grow. Smaller File under Quality gives the smallest output, and H.265 in the Codec setting (MP4, MOV and MKV) is usually smaller than H.264 at similar quality but plays on fewer devices.
Na faele ea HLS e tla bapala ka iPhone / Android / Smart TV?
