Test foto estrapolate da video

Messaggioda gipi55 » 19/04/2015, 20:59

Mi sono chiesto piu volte se conviene ancora scattare foto in un evento fuggente e irripetibile, nel senso impostare booster per prendere 30 foto in pochi secondi o alzare la qualità video il piu possibile , per poi scegliere con calma fra migliaia e migliai di fotogrammi, visto che la qualità video nelle gopro e cresciuta tantissimo, mentre non è stato cosi altrettanto per la foto.
Si è visto piu volte nel web bellissime foto estrapolate da video
Un piccolo mio test senza pretese e pure criticabile credo! : Sailor :
Ho fatto vari filmati in diversi formati e preso un fotogramma ne ho ingrandito un particolare per evidenziare la qualità.
Le ho estrapolate tutte con VLC perche non ho altri programmi che mi facciano vedere il 4k
Allora ..
DA 4K 17:9 ( formato foto 4096x2160 )

DA 4K 16:9 ( formato foto 3840x2160)

DA 2,7K 17:9 ( formato foto 2704x1440)

DA 2,7K 16:9 (formato foto 2704x1524)

1080 A 60 FPS ( formato foto 1920x1080)

1080 A 30 FPS ( formato foto 1920x1080)

e naturalmente normale foto a 12 mp (formato 4000x3000)

Bè! : Chessygrin : non ci piove sopra! anche se il formato 4k ha le dimensioni quasi della singola foto 4096x2160, non regge il confronto con il jpg 4000x3000
in oltre al formato 1080 scende molto la qualità anche con la sola differenza di 30 fps e 60 fps.
OK : Sailor : comunque io sono del parere che queste differenze le possiamo notare solo per ingrandimenti o per stampe
Difficile! o poco si nota se inserite nel web
Comunque
