tso tawm ib tug dawb non-linear video editing system . Txoj haujlwm code yog muab nyob rau hauv daim ntawv tso cai GPLv3: lub interface yog sau rau hauv Python thiab PyQt5, video processing core (libopenshot) yog sau rau hauv C ++ thiab siv lub peev xwm ntawm FFmpeg pob, kev sib tham ncua sij hawm yog sau siv HTML5, JavaScript thiab AngularJS . Rau cov neeg siv Ubuntu, pob khoom nrog OpenShot tso tawm tshiab yog muaj los ntawm kev npaj tshwj xeeb , rau lwm yam kev faib tawm Kev sib dhos tus kheej hauv AppImage hom. Tsim muaj rau Windows thiab macOS.
Tus editor nta tus neeg siv-phooj ywg thiab intuitive user interface uas tso cai rau cov neeg siv tshiab los hloov cov yeeb yaj kiab. Qhov kev zov me nyuam txhawb nqa ntau ntau qhov kev pom pom, tso cai rau koj ua haujlwm nrog ntau lub sijhawm taug qab nrog lub peev xwm txav cov ntsiab lus ntawm lawv nrog tus nas, tso cai rau koj ntsuas, qoob loo, sib koom ua ke video blocks, xyuas kom meej ntws ntawm ib qho video mus rau lwm qhov, overlay translucent thaj chaw, thiab lwm yam. Nws yog ua tau rau transcode video nrog saib ua ntej ntawm cov kev hloov ntawm ya. Siv cov tsev qiv ntawv ntawm FFmpeg qhov project, OpenShot txhawb nqa ntau tus yees duab, suab thiab duab tawm tswv yim (xws li kev txhawb nqa tag nrho rau SVG).
Hauv qhov kev tso tawm tshiab:
- Txhawb kho vajtse acceleration ntawm video encoding thiab decoding siv GPU es tsis txhob CPU. Cov hom kev nrawm txhawb los ntawm daim npav video thiab cov tsav tsheb tau teeb tsa tau tshwm sim hauv ntu "Preferences->Performance" seem. Rau NVIDIA video phaib, tsuas yog encoding acceleration tam sim no txaus siab yog tias tus tswv NVIDIA 396+ tsav tsheb muaj. Rau AMD thiab Intel phaib, VA-API (Video Acceleration API) yog siv, uas yuav tsum muaj kev teeb tsa ntawm mesa-va-drivers lossis i965-va-driver pob. Nws muaj peev xwm siv ntau GPUs - piv txwv li, ntawm cov khoos phis tawj nrog cov duab sib xyaw, cov Intel GPU built-in tuaj yeem siv los ua kom nrawm nrawm, thiab GPU ntawm daim npav tsis sib xws tuaj yeem siv rau kev txiav txim siab. Cov theem ntawm kev ua tau zoo nrog kho vajtse acceleration nyob ntawm cov video hom thiab nws cov kev txhawb nqa los ntawm daim video card, piv txwv li, rau MP4 / H.264 cov ntaub ntawv muaj ib tug nce nyob rau hauv ceev ntawm kev txiav txim siab thiab encoding pixel cov ntaub ntawv los ntawm 30-40%;
- Qhov kev ua tau zoo ntawm cov txheej txheem keyframe tau nce ntau ntxiv (los ntawm ntau qhov kev txiav txim ntawm qhov loj), uas tau sau dua tshiab thiab tam sim no muab cov txiaj ntsig sib cuam tshuam nyob ze lub sijhawm. Cov txheej txheem tshiab tso cai rau koj los tsim txog 100 txhiab tus txiaj ntsig sib cuam tshuam nyob rau lub sijhawm uas nyob rau hauv lub qub system nws coj los tsim ib qho nqi, uas ua rau nws muaj peev xwm tshem tawm cov txheej txheem caching yav dhau los. Yav dhau los, txawm hais tias siv lub keyframe cache, hauv cov haujlwm uas muaj ntau cov clips, kev ua haujlwm ntawm keyframe processing system tau degraded heev thiab muaj kev ncua loj thaum nkag mus rau keyframes lossis thaum tsiv mus rau ncua sij hawm;
- Ntxiv kev txhawb nqa rau kev xa tawm thiab xa tawm cov ntaub ntawv hauv EDL thiab XML hom siv hauv Adobe Premiere thiab Final Cut Pro pob, uas muab cov ntaub ntawv hais txog cov ntaub ntawv, clips, keyframes, kev hloov pauv thiab ncua sij hawm muaj nyob rau hauv qhov project;
- Thumbnail tiam tau txhim kho zoo heev. Cov teeb meem nrog cov duab me me ploj tom qab tsiv los yog hloov npe cov npe tau raug daws lawm. Hauv qhov project, cov peev txheej cuam tshuam tam sim no tau muab khaws cia rau hauv ib daim ntawv teev npe cais, thiab tsim thiab ua cov duab me me, siv HTTP server hauv zos, txheeb xyuas cov npe sib txawv, txheeb xyuas cov ntaub ntawv uas ploj lawm thiab rov tsim cov duab me me uas ploj lawm (lub interface thiab ncua sij hawm yog raws li kev siv. HTML technologies thiab tam sim no thov cov duab thumbnail los ntawm built-in HTTP server);
- Ntxiv kev txhawb nqa rau Blender 3D qauv tso tawm ΠΈ , nrog rau kev txhawb nqa rau ".blend" hom ntawv. Feem ntau ntawm cov animated npe npaj hauv Blender tau hloov kho. Txhim kho logic rau kev txiav txim siab version thiab executable ntaub ntawv ntawm Blender;
- Lub peev xwm los tsim cov thaub qab thiab rov qab lub xeev yav dhau los thaum muaj kev ua tsis tiav lossis yuam kev yuam kev tau ua tiav. Piv txwv li, yog tias tus neeg siv yuam kev tshem tawm cov clips los ntawm ncua sij hawm thiab AutoRecord txuag qhov kev hloov pauv no, tus neeg siv tam sim no muaj peev xwm yob rov qab mus rau ib qho ntawm cov thaub qab yav dhau los (yav tas los AutoRecord hloov cov ntaub ntawv tseem ceeb, tab sis tam sim no cov ntaub ntawv nruab nrab ntawm cov thaub qab tau txais kev cawmdim hauv ~/. openshot_qt/recovery/);
- Txhim kho kev sib raug zoo nrog cov duab vector hauv hom ntawv
SVG. Kho ntau SVG teeb meem ntsig txog pob tshab, fonts, thiab lwm yam. Kev tso tawm tshiab ntawm lub tsev qiv ntawv tau ntxiv rau cov khoom siv rau kev ua SVG ; - Txhim kho qhov rais saib ua ntej. Thaum hloov qhov loj ntawm lub qhov rais, qhov ntsuas tam sim no tau xaiv tsuas yog nyob rau hauv qhov tseem ceeb uas tso cai rau qhov loj me yuav tsum tau muab faib los ntawm ob yam tsis muaj qhov seem, uas tshem tawm cov tsos ntawm voids ntawm cov npoo ntawm daim duab;
- Txhim kho export system. Thaum xa tawm ntawm tus nqi sib txawv, cov ntaub ntawv tseem ceeb hauv qhov project tsis hloov lawm (yav dhau los, qhov tseem ceeb thav duab tau siv, uas tuaj yeem ua rau poob ntawm cov ntaub ntawv thaum xa tawm ntawm FPS qis);
- Los ntawm lub neej ntawd, kev xa xov hluav taws xob tsis siv neeg raug kaw thaum thawj zaug tso tawm. Kev ntsuas raug xa tsuas yog tias tus neeg siv pom zoo rau kev xa cov metrics tsis qhia npe, suav nrog cov ntaub ntawv hais txog cov qauv ntawm cov tsev qiv ntawv thiab cov khoom siv hauv lub cev, nrog rau cov ntaub ntawv hais txog qhov yuam kev uas tshwm sim. Txhawm rau paub meej tias kev tso cai xa telemetry ntawm thawj lub community launch, qhov tshwj xeeb dialog tam sim no tau tshwm sim, qhov kev xaiv xa hauv uas tau qhib los ntawm lub neej ntawd thiab cim "Yog, Kuv xav txhim kho OpenShot," uas tuaj yeem ua yuam kev yam tsis tau nyeem ntawv hauv qhov rais;
- Ntau qhov kev txhim kho tau ua rau lub kaw lus tsim thiab CMake-based tsim cov ntawv. Txhim kho kev txhawb nqa rau kev txhim kho txuas ntxiv hauv Travis CI thiab GitLab CI;
- Txhim kho cross-platform compatibility. Cov txheej txheem xeem tau nthuav dav thiab cov yam ntxwv ntawm cov kev khiav hauj lwm sib txawv tau raug coj mus rau hauv tus account. Muab kev sib luag hauv kev ua haujlwm thiab kev txhawb nqa rau Linux, Windows thiab macOS.
