Hafainganan'ny fanatsarana AVI FAQ
How does Change AVI 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. AVI is the 1992 Microsoft container: broad codec support but no modern streaming features, no B-frame-friendly indexing and poor subtitle handling. That determines whether the retimed result can be written back cheaply or has to be fully re-encoded.
Anything specific to AVI here?
+
Yes — AVI has no modern index or B-frame-friendly structure, so accurate seeking usually requires a real re-encode rather than a copy. 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.
Miasa amin'ny finday ve izy io?
+
Eny, miasa tsara amin'ny finday avo lenta sy takelaka ny mpanova rakitra anay. Azonao atao ny mamadika rakitra amin'ny iOS, Android, ary sehatra finday hafa rehetra miaraka amin'ny navigateur maoderina.
Iza avy ireo navigateur tohana
+
Miasa amin'ny navigateur maoderina rehetra ny mpanova anay, anisan'izany ny Chrome, Firefox, Safari, Edge, ary Opera. Manoro hevitra anao izahay mba hanavao hatrany ny navigateur-nao mba hahazoana traikefa tsara indrindra.
Voatahiry ho tsiambaratelo sy azo antoka ve ny rakitrako
+
Eny tokoa. Voakarakara soa aman-tsara ny rakitrao ary voafafa ho azy avy amin'ny mpizara anay rehefa avy niova fo. Tsy mamaky, mitahiry, na mizara ny votoatin'ny rakitrao izahay. Mampiasa fifandraisana HTTPS voaaro ny famindrana rehetra.
Ahoana raha tsy manomboka ny fampidinako
+
Raha tsy manomboka ho azy ny fampidinanao dia andramo tsindriana indray ny bokotra fampidinana. Ataovy azo antoka fa tsy voasakana ny pop-up, ary jereo ny lahatahiry fampidinana ao amin'ny navigateur-nao. Azonao atao ihany koa ny manindry havanana ny rohy fampidinana ary misafidy ny 'Tehirizo ho'.
Ho voatazona ve ny kalitao
+
Mijanona ho tsara ny kalitaon'ny horonan-tsary mandritra ny fanodinana azy. Miankina amin'ny rakitra loharano sy ny endrika kendrena ny vokatra.
Mila mamorona kaonty ve aho
+
Tsy mila kaonty ianao amin'ny fampiasana tsotra. Afaka mikirakira rakitra avy hatrany ianao. Ny famoronana kaonty maimaim-poana dia ahafahanao miditra amin'ny tantaran'ny fiovam-po sy ireo endri-javatra fanampiny.
