Tweak FLV Hitrost Pogosta vprašanja
How does Change FLV Speed change the playback rate?
+
Concretely, the presentation timestamps are rescaled and the audio is time-stretched to match with pitch preserved, so picture and sound stay in sync; large speed-ups also drop redundant frames rather than just playing them faster. Choose a multiplier — 0.5x for half speed, 2x for double — and the whole file is retimed.
Will speeding it up make voices sound high-pitched?
+
No. The time-stretch preserves pitch, so a 1.5x speech track sounds like the same person talking faster rather than like a chipmunk. That is the difference between a proper time-stretch and simply playing the samples faster.
Does the source format affect the result?
+
It does. FLV is the retired Flash container — nothing plays it natively any more, which is normally the reason it is being converted. That determines whether the retimed result can be written back cheaply or has to be fully re-encoded.
Anything specific to FLV here?
+
Yes — nothing plays FLV natively any more, so the practical end of any FLV job is a modern container. Worth knowing before you commit to a large speed change.
How far can I push the speed before it sounds wrong?
+
Roughly 0.75x to 2x is transparent for speech. Beyond about 2.5x the stretch artefacts become audible on any algorithm, and below 0.5x the reconstruction has to invent too much. Music tolerates far less than speech does.
Do picture and sound stay in sync?
+
Yes. Both are retimed by the same factor in one operation, so they cannot drift apart — which is the usual failure when speed is changed by editing the two streams separately.
Ali deluje na mobilnih napravah
+
Da, naš pretvornik je popolnoma odziven in deluje na pametnih telefonih in tablicah. Datoteke lahko pretvorite v sistemih iOS, Android in kateri koli drugi mobilni platformi s sodobnim brskalnikom.
Kateri brskalniki so podprti
+
Naš pretvornik deluje z vsemi sodobnimi brskalniki, vključno s Chromeom, Firefoxom, Safarijem, Edgeom in Opero. Za najboljšo izkušnjo priporočamo, da svoj brskalnik posodabljate.
Ali so moje datoteke zasebne in varne?
+
Seveda. Vaše datoteke so varno obdelane in po pretvorbi samodejno izbrisane z naših strežnikov. Vsebine vaših datotek ne beremo, ne shranjujemo in ne delimo. Vsi prenosi uporabljajo šifrirane povezave HTTPS.
Kaj pa, če se prenos ne začne
+
Če se prenos ne začne samodejno, poskusite znova klikniti gumb za prenos. Prepričajte se, da pojavna okna niso blokirana, in preverite mapo za prenose v brskalniku. Lahko pa z desno miškino tipko kliknete povezavo za prenos in izberete »Shrani kot«.
Se bo kakovost ohranila
+
Kakovost videa med obdelavo in pretvorbo ostane nespremenjena. Rezultati so odvisni od združljivosti izvorne datoteke in ciljne oblike zapisa.
Ali moram ustvariti račun
+
Za osnovno uporabo ni potreben račun. Datoteke lahko obdelate takoj. Z ustvarjanjem brezplačnega računa dobite dostop do zgodovine pretvorb in dodatnih funkcij.
