MPG kuya TIFF Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiyikhipha kanjani ifreyimu kusuka ku MPG ividiyo njenge TIFF izithombe?

Layisha i-MPG bese uvula izinketho. Ukukhishwa kwefreyimu kunezindlela ezimbili: Ifreyimu eyodwa igcina i-TIFF eyodwa kusuka ku-second ofaka (njengesibonelo 1, 5 noma 10.5), futhi Zonke ifreyimu zigcina ifreyimu ngayinye yevidiyo njengesithombe se-TIFF. Akukho indlela ngayinye-Nth-frame noma eyodwa-kwesekunxele. MPG iyi-MPEG i-program stream efanayo ne-.mpeg — isibonisi sokubhala esithathu siyi-DOS-era truncation, hhayi i-format ehlukile. I-TIFF iyifomethi yefayela lesithombe ephawulwe kusukela ngo-1986, futhi iyifomethi yokuskena, ukushicilela kanye nokugcinwa kwefayela ezimbonini ezijwayelekile.

Ingabe ngithola ama-TIFF amafreyimu ngaphandle kwesihloko?

Uma nje i MPG ayizange itshetshezwe, ngoba MPG ayinaso isingeniso esikhethiwe sohluzo esikhethiwe sokuvala. Noma yini eMPG ebonisa esigabeni isithombe, ngakho i TIFF ngayinye ikhiqiza ukukhishwa futhi akukho sinqumo esisusayo ngemuva. lapho ihele elihlukile lesihloko likhona eduze kwevidiyo, khipha kusuka emthonjeni ogcina ama-2 ahlukene futhi ama-frames aphuma ahlanzekile. MPG ithola wonke ama MPEG-2 amaphutha - i-bitrate enzima, ukuxhuma, akukho ngezansi okuthambile - kanye nokungqubuzana kwezinhlamvu ezimbili ezibanzi zefomethi eyodwa.

Ingabe i-TIFF ixhasa ukubukhali?

Ifomethi ikhona, kodwa umsuka awuna-alpha ukuwunika - amafreyimu wevidiyo namakhasi ashicilelwe agcwele ukucasuka, ngakho wonke ama-pixel afika aqinile. Isixhumanisi se-alpha sisebenza ngemuva: kusho ukuthi ungasakaza isiqephu se TIFF ngemuva ngaphandle kokushintsha ifomethi futhi. I-TIFF iphatha i-CMYK, 16-bit ububanzi, i-ICC efakwe ngaphakathi namaprofayili namadokhumende amakhasi amaningi, okuwukuthi okuthile okudingayo ukuphrinta nokugcinwa kwemisebenzi.

Ingabe amafayela TIFF azokhula kangako?

Okuningi kunalokho okubonayo, ngoba TIFF igcina wonke ama-pixel ngokugcwele kungafani nokulinganisela. I-1080p ihlala ifinyelela ku-2-5 MB futhi i-4K ihlala ifinyelela ku-6-15 MB, ngakho-ke ukukhishwa okude kusebenza ngokushesha. Lokhu kuyibhizinisi elilungile uma izithombe zidla ukukhiqizwa okuqhubekayo, futhi okubi uma zihamba ngqo kwikhasi le-web. I-TIFF iyindawo yokuqoqa engaphezu kwe-codec: ingagcina idatha engacindezelwanga, i-LZW, i-ZIP noma i-JPEG, kuze kube yi-32 bits ngasinye, ngekhasi eliningi kwifayela elilodwa.

Ngabe usinqumo sinjani uma ifreyimu ngayinye ekhishwayo TIFF iphuma?

Ukulungiswa okufanayo njenge MPG ividiyo — 1080p MPG ikhiqiza amafreyimu angama-1920×1080 TIFF; 4K MPG ikhiqiza amafreyimu angama-3840×2160 TIFF. Sebenzisa ukuguqula usayizi ngemuva kokukhipha uma ufuna amathumbnail amancane noma ama-social-media-size crops.

Ingabe ngizokhipha ifreyimu ngayinye esuka ku MPG njenge TIFF?

Yebo, ngezo zonke iframes ku-Frame Extraction option, kodwa bheka ukubala: iminithi eyodwa ye-30 fps video inikeza izithombe ezingu-1,800 TIFF. Uma uhlala uhlala, khetha i-Frame eyodwa bese ufaka isithupha ofuna.

Ingabe izithombe ezikhishwayo TIFF zizogcina umbala MPG olinganiselwe?

Ividiyo ye-HDR ayimaphulwe ngethoni: ifreyimu ngayinye iguqulwa kusuka ku-MPG njengoba ikhodwe, ngakho ifreyimu kusuka ku-HDR MPG ingabonakali iphazili noma ihlanzwe njenge-TIFF. Ividiyo ejwayelekile (SDR) igcina imibala yayo.

Yini ubukhulu behele lwesiphequluli esisodwa esikhishwayo TIFF?

Kuxhomekeka kusinqumo kanye ne TIFF codec. Ifreyimu ye-1080p PNG ivame ukuba 2 kuya ku-5 MB; i-1080p JPG esezingeni-85 ivame ukuba 200 kuya ku-500 KB; i-4K PNG ivame ukuba 6 kuya ku-15 MB. Kunzima kakhulu, ukukhishwa kwefreyimu ngayinye ye-PNG yemizuzu engu-10 1080p MPG kukhiqiza ~50 GB jikelele.

Ingabe ithatha isikhathi esingakanani ukukhishwa kwefremu kusuka ku MPG kuya ku TIFF?

Kuxhomekeka kubukhulu nesikhathi sohele. Amadokhumende amancane namasithombe avame ukulungiselelwa ngokushesha. Amavidiyo ade athatha isikhathi eside, ngoba amavidiyo aguqulwa aphinde akhode ifreyimu ngayinye.

Ingabe ngizokhipha amafreyimu ezikhathini ezikhethekile ku MPG?

Omunye ngasikhathi sinye. Ifremu eyodwa ithatha isikhathi esisodwa emaminithini (njengesibonelo 83 ku-1:23) futhi igcina ifremu njenge-TIFF. Akukho indawo yohlu lwezikhathi, ngakho sebenzisa ukuguqulwa kabusha kosuku ngalunye olungeziwe.

Ingabe i-MPG yami yevidiyo ifihlakele ngesikhathi sokukhipha ifreyimu?

Yebo. Amafayela MPG alayishwe phezulu aphathwa kumaseva ethu okuguqula, akukho muntu obhekana nawo, futhi angeke ahlukaniswe. Ukulayishwa kanye nokuguqulwa kwe TIFF kususwa ngokuzenzakalela cishe amahora angu-24 ngemuva kokuguqulwa, okushiya isikhathi sokulanda imiphumela. Bona /privacy/ ukufinyelela kunqubomgomo egcwele.

MPG

MPG iyividiyo efanayo ye-MPEG-1 noma i-MPEG-2 njenge-.mpeg, kuphela isibonisi esincane sesoftware yesikhathi se-DOS esidingekayo.

TIFF

Amafayela e-TIFF asekela ukujula kwe-bit ephezulu kanye nokucindezelwa okungenakulahlekelwa, okulungele ukuthwebula izithombe zobungcweti kanye nokuphrinta.
