MP4 Tuhinga o mua PNG Ngā Pātai Auau mō te Tahuritanga

He pēhea te tango i ngā tāruatanga mai i tētahi MP4 video hei PNG whakaahua?

Upload the MP4 and open the options. Frame Extraction has two modes: Single Frame saves one PNG from the second you enter (for example 1, 5 or 10.5), and All Frames saves every frame of the video as a PNG image. There is no every-Nth-frame or one-per-second mode. Ko MP4 te ISO/IEC 14496-14, i paerewa i te tau 2001, ā, i puta mai i te āhua o te kāwai pēnei i te QuickTime e whakamahia ana e MOV. I hangaia a PNG i te tau kotahi mano e 1996 hei whakakapi kore whakawhiwhinga ki te GIF, ā, ka noho hei hanga whakaahua pātata kore ngaro o te Wīwī.

Ka puta ake te whakataki i roto i ngā tātai PNG ka tāruatia?

Kāore mēnā he whakataki whakahuatuhi tūturu rātou. Ka pupuri te MP4 i ngā whakahuatuhi hei ā rātou ake rerenga, ā, ka tātuhia e te kaiwhakaari i runga i te whakaahua i te wā whakataetae, nō reira ko te tātai whakakōrero e tuhi ana i waho hei PNG he pikorata mārō i raro i te PNG. Ko ngā whakahuatuhi i whakamārōtia ki roto i te ataata i mua i te noho he MP4 he mea rerekē — i taua wā he wāhanga o te whakaahua, ā, ka pupuritia e ia tātai whakahuatuhi i a rātou.

E tautoko ana te huaputa PNG i te mārama?

Ko te āhua o te āhua, engari kāore he pūtake ā-arawhiti hei hoatu ki a ia — he tino mārama ngā tāruatanga ataata me ngā pātaka i whakawāteatia e te āhua, nā reira ka tae mai ia pikitia ki te mārō. He tino whai hua tonu te kanikani ā-arawhiti i muri mai: ko te tikanga ka taea e koe te whakaiti i tētahi kaupapa mai i te PNG i muri ake, kāore i te huri i te āhua. Ko PNG te kōwhiringa tika mō ngā whakaahua mata, ngā tohu, ngā toi raina me ētahi atu mea me ngā taitapa mārō, mārama rānei — kāore he whakawhāiti, kāore he tae.

He nui rawa te PNG o nga faila?

He nui ake i te mea e tūmanako ana koe, nā te mea ka pupuri te PNG i ia pikitia kia tika, kaua e tata. Ko te 1080p e noho tonu ana i te 2-5 MB, ā, ko te 4K e noho tonu ana i te 6-15 MB, nā reira ka tere te tāpiri i te whakawāteatanga roa. Ko te hokohoko tika tonu tēnei ina kai te whakaahua i te whakamātautau anō, ā, ko te mea hē ina haere hāngai ki tētahi pou tītaka. Ka whakamahia e PNG te whakawhāititanga DEFLATE i runga i ngā raina tātari tātari, kia ora ai ia pikitia, tae atu ki tētahi kanikani ā-arawhiti 8-biti.

I te rongoā pēhea e puta mai ai ia whāriki i tangohia PNG?

The same resolution as the MP4 video — a 1080p MP4 produces 1920×1080 PNG frames; a 4K MP4 produces 3840×2160 PNG frames. Use the resize utility after extraction if you want smaller thumbnails or social-media-sized crops.

Ka taea e au te whakawātea i ia tāpare kotahi mai i te MP4 hei PNG?

Yes, with All Frames in the Frame Extraction option, but watch the count: one minute of 30 fps video gives 1,800 PNG images. For a single still, choose Single Frame and enter the second you want instead.

Ka pupuri te PNG whakaahua i te rangi o te MP4?

HDR footage is not tone-mapped: each frame is converted from the MP4 as it is decoded, so a frame from an HDR MP4 can look flat or washed out as a PNG. Standard (SDR) video keeps its colours.

He aha te rahi o te rārangi pūranga o tētahi tāruatanga PNG?

E ai ki te rongoā me te pūkōrero PNG. Ko te āhua o te tāpare 1080p PNG ko te 2 ki te 5 MB; ko te JPG 1080p i te āhuatanga-85 ko te 200 ki te 500 KB; ko te 4K PNG ko te 6 ki te 15 MB. I te tino, ko ia tāruatanga PNG-whāiti o te 10-rohe 1080p MP4 e whakaputa ana i ~50 GB katoa.

He maha te wā e hiahiatia ana te whakawāteatanga rārangi mai i te MP4 ki te PNG?

It depends on the size and length of the file. Small documents and images are usually ready quickly. Long videos take the longest, because most video conversions re-encode every frame.

Ka taea e au te whakawātea i ngā tāpare i ngā wā tauwhāiti i roto i te MP4?

One at a time. Single Frame takes one time in seconds (for example 83 for 1:23) and saves that frame as a PNG. There is no field for a list of times, so run the conversion again for each extra timestamp.

He tūmataiti te MP4 o ahau video i te wā o te whakawāteatanga whāriki?

Yes. Uploaded MP4 files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted PNG are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
