Dondosha faili, au

URL inayoelekeza kwenye video rejeleo inayotumiwa kuongoza mwendo na muundo.

resolution chaguomsingi auto

Vipimo vya video ya tokeo, ambavyo pia huathiri muda thabiti: ukubwa mdogo huruhusu fremu zaidi, huku mkubwa ukipunguza kiwango cha juu. Makadirio ya udhibiti yaliyojengwa ndani huweka ukubwa karibu na mtiririko rasmi wa udhibiti; udhibiti wa moja kwa moja kupitia `skip_control_preprocess` na `control_video_url` huheshimu vipimo vilivyobainishwa kwa ulinganifu wa 64. Katika hali ya udhibiti wa moja kwa moja, `auto` hurithi vipimo na uwiano wa chanzo ndani ya mipaka ya LTX.

num_frames chaguomsingi 121

Idadi ya fremu za tokeo, kulingana na bajeti ya uthabiti ya IC-LoRA inayotegemea mwonekano kuzidishwa kwa fremu. Jibu la 422 linamaanisha bajeti hiyo imezidiwa: punguza mwonekano au `num_frames`. Bajeti inaruhusu takribani fremu 150 kwa vipimo vya daraja la 720p na zaidi kwa ukubwa mdogo.

control_video_url

Dondosha faili, au

Video ya hiari ya udhibiti iliyohesabiwa awali, inayotumiwa badala ya makadirio ya udhibiti yaliyojengwa ndani inapotolewa pamoja na `skip_control_preprocess`. Inakuwa ishara ya moja kwa moja ya udhibiti baada ya kubadilishwa ukubwa ili kuendana na vipimo vya tokeo na idadi ya fremu. Video inaweza, kwa mfano, kuwa na mchanganyiko wa kina, kingo au mkao uliotengenezwa tayari.

image image_url

Dondosha faili, au

Mtindo wa hiari wa kuweka picha nanga au utambulisho wa mhusika kama fremu muhimu ya kwanza.

mid_image_url

Dondosha faili, au

Mwonekano wa hiari wa kuweka picha nanga karibu na katikati ya klipu, ukikamilisha fremu muhimu ya awali ya `image_url`. Husaidia mwonekano kufuatilia mwendo wa kamera badala ya kuyumba; inahitaji `image_url`.

end_image end_image_url

Dondosha faili, au

Mwonekano wa hiari wa kuweka picha nanga kwenye fremu ya mwisho ya klipu. Ni muhimu mwendo wa kamera unapoishia mahali tofauti na picha ya kuanzia; inahitaji `image_url`.

video_quality chaguomsingi high

Preset ya ubora inayotumika kwenye video ya tokeo.

video_write_mode chaguomsingi balanced

Hali ya kuandika ya video inayotokana.

video_strength chaguomsingi 0.6

Uhuru wa kubadilisha mwendo na muundo kutoka kwenye video rejeleo hudhibitiwa na nguvu hii ya urekebishaji: mipangilio midogo huruhusu mabadiliko makubwa zaidi.

strength chaguomsingi 1

Udhibiti wa kuondoa kelele kwa sampuli za video-kwa-video za rejeleo, ambao athari yake hutegemea `preserve_original_video`. Hali hiyo ikiwa imezimwa, hupunguza tu ratiba ya kuondoa kelele; ikiwa imewashwa, hudhibiti ubadilishaji wa pikseli za chanzo, ambapo 1.0 huzalisha kila kitu upya na mipangilio ya chini huhifadhi zaidi.

frames_per_second chaguomsingi 24

Kiwango cha fremu za video ya tokeo, kinachopimwa kwa fremu kwa sekunde.

num_inference_steps chaguomsingi 15

Weka idadi ya hatua za inference za kuendesha, hadi 30; kuiacha bila kubadilishwa hutumia 15.

guidance_scale chaguomsingi 1

Rekebisha mwongozo usio na classifier kwa kutumia kipimo hiki; urekebishaji wake chaguomsingi hulenga ubora wa juu na uzalishaji wa haraka.

seed

Seed inayofanya uzalishaji uweze kurudiwa. Kuiweka kuwa None huchagua seed bila mpangilio.

Kuhusu Ltx 2.3 Quality · Reference Video to Video

Huunda video mpya kutoka kwa `prompt` inayohitajika na `video_url` ya marejeleo inayotoa mwendo na muundo. `image_url`, `mid_image_url` na `end_image_url` za hiari huweka mwonekano wa mwanzo, kati na mwisho. `video_strength` na `strength` (zote 0 to 1) hudhibiti jinsi inavyofuata au kuhifadhi chanzo, na `control_video_url` inaweza kutoa ishara ya udhibiti iliyokokotolewa awali. `resolution` hutoa mipangilio ya kiotomatiki au thabiti kama mraba na picha ya wima au mlalo ya 16:9.
