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.
Ka mahi i runga i ngā taputapu pūkoro
+
Ae, he tino arotau tā mātou kaitahuri, ā, ka mahi i runga i ngā waea atamai me ngā papa. Ka taea e koe te tahuri i ngā kōnae i runga i te iOS, Android, me tētahi atu tūāpapa pūkoro me tētahi pūtirotiro hou.
Ko ēhea ngā pūtirotiro e tautokona ana
+
Ka mahi tahi tā mātou kaitahuri me ngā pūtirotiro hou katoa tae atu ki a Chrome, Firefox, Safari, Edge, me Opera. Ka tūtohu mātou kia whakahoutia tonutia tō pūtirotiro kia pai ai te wheako.
Kei te noho tūmataiti, kei te haumaru hoki aku kōnae?
+
Ae rawa. Ka tukatukahia ō kōnae me te haumaru, ā, ka mukua aunoa mai i ā mātou tūmau i muri i te tahuritanga. Kāore mātou e pānui, e rongoa, e tohatoha rānei i ngā ihirangi o tō kōnae. Ka whakamahia e ngā whakawhiti katoa ngā hononga HTTPS kua whakamunatia.
Me pēhea mēnā kāore taku tikiake e tīmata?
+
Ki te kore tō tango e tīmata aunoa, ngana anō ki te pāwhiri i te pātene tango. Kia tino mohio kāore ngā pahū-ake e āraia, ā, tirohia te kōpaki tango o tō pūtirotiro. Ka taea hoki e koe te pāwhiri-matau i te hononga tango, kātahi ka tīpako i te 'Tiaki Hei'.
Ka tiakina te kounga
+
Ka noho tonu te kounga o te ataata i te wā e tukatukahia ana i te wā e tahurihia ana. Ka whakawhirinaki ngā hua ki te hototahitanga o te kōnae pūtake me te hōputu ūnga.
Me hanga e au he pūkete
+
Kāore he pūkete e hiahiatia ana mō te whakamahinga taketake. Ka taea e koe te tukatuka i ngā kōnae tonu. Mā te waihanga i tētahi pūkete kore utu ka taea e koe te uru atu ki tō hītori tahuritanga me ngā āhuatanga tāpiri.
