    Re: Davinci Resolve Updates

    Καλησπέρα

    Έχω την εξής ερώτηση παιδιά. Έστω ότι έχεις τραβήξει ένα πλάνο με μια Sony a6500 4K 25 fps.. Ως γνωστόν το bitrate στη κάμερα είναι 100Mbps. Αν θέλεις να κάνεις deliver (export) πως μπορείς να εξάγεις με τη λιγότερη δυνατή απώλεια το αρχείο σου ??

    Υποθέτω ότι δεδομένου ότι το bitrate είναι 100 Mbps, δεν έχει νόημα να πας παραπάνω ή παρακάτω οπότε το ξαναβάζω restricted to 100000kbps
    Βάζω (φαντάζομαι σωστά) το encoding profile στο high
    και μετά υπάρχει μια επιλογή για την οποία κανείς δεν έχει μιλήσει σε κανένα βίντεο που έχω δει και είναι το "keyframe" το οποίο από default είναι στο 12 (βλέπε φώτο). Αν βάλω το keyframe στο 1 τι ακριβώς επηρεάζει. Από 1-2 τεστ που έκανα σε βίντεο με banding στα χρώματα, νομίζω ότι με το keyframe στο 1 είχα καλύτερο αποτέλεσμα.

    Καμιά ιδέα ?

    Re: Davinci Resolve Updates

    ενα αναλυτικο αρθρο για το θθεμα....
    https://video.ibm.com/blog/streaming...o-compression/

    Προσωπικα δεν το πειραζω, αλλα δε χανεις να δοκιμασεις.

    συνηθως, αν θελω να εχω μια "μητρα" εξαγωγης οσο καλυτερη γινεται, επιλεγω prores 444 (mac) ή DNX HQX (PC) και μετα κανω οτι format θελω απο εκεινο.


    με λιγα λογια...


    The keyframe distance is the maximum number of frames before the encoder inserts an i-frame, which is the highest-quality frame of an MPEG stream (ie, it has all the information for a single frame of video inside of it rather than relying on the frames around it to reconstruct). In between the i-frames are b-frames and p-frames, which are "difference" frames that reconstruct that frame of video by looking at the nearest i-frame and applying all the "difference" frames from that point forward (or backwards). The collection of an i-frame and all its connected p-frame and b-frames is called a GOP, or "Group of Pictures". So in essence the "keyframe distance" value determines the length of each GOP.

    Note that Premiere automatically inserts a new i-frame for scene changes, irrespective of the keyframe distance value. This is to assure video quality at the start of a new scene since there wont be enough in common from previous b-frame and p-frames.

    Generally speaking, the more i-frames you have, the higher the image quality of video, but also the larger the size of the video. So the value you choose for keyframe distance is a balance between the file size you want the video to fit in vs quality. If you're not concerned with file size or the file size generated is within reason then you can just leave it to its default value. Otherwise you can tweak it as part of the process to get the file size down to where you want it to be (in combination with the other encoder parameters such as bitrate).

    Re: Davinci Resolve Updates

    Καλησπέρα σε όλους και καλό χειμώνα ? (ή να μην το πω ακόμα)

    Είπα τον Αύγουστο να αφιερώσω λίγο παραπάνω χρόνο στο Davinci Resolve. Η αλήθεια είναι ότι στη χρωματική επεξεργασία μου φαίνεται ανώτερο από το Premiere. Για την ακρίβεια αρκετά ανώτερο ενώ στα θετικά επίσης αναμφίβολα θα έβαζα και το γεγονός ότι πάει σφαίρα όταν το Premiere δυσκολεύεται ακόμα και σε 1080p (το 4Κ ειδικά σε 50fp, είναι σκέτο δράμα), ειδικά με εφφε.

    ΟΜΩΣ, πέραν των ανωτέρω, αρχίζει και μου φαίνεται κάπως μπελαλίδικο σε ότι αφορά εφφέ και transtition. Στο Premiere έχεις πάρα πολλές επιλογές με ένα drug and drop.. π.χ. θες να βάλεις ένα εφφέ glitch, drug & drop με τα keyframes και ολα τα καλά. Εδώ είδα ότι τα εφφέ είναι αρκετά περιορισμένα και απο μερικά video στο youtube διαπίσωσα ότι οι περισσότεροι ανοίγουν το tab του Fusion για να κάνουν το οτιδήποτε πέραν των εργοστασιακών ή αρχιζουν μια χρονοβόρα διαδικασία στο color tab.
    Υπάρχει κάτι που χάνω ? Ισως να μην τα λέω και καλά γιατί μόλις ένα μήνα αποφάσισα να ασχοληθώ σοβαρά και η αλήθεια είναι ότι ο αρχικός ενθουσιασμός ειδικά στο colour grading αρχίζει και χάνεται από τον περιορισμό σε διάφορα εφφέ που θα ήθελα και στο Premiere είναι πιο άμεσα χωρίς να χρειάζεται να μάθει κανείς τις εντολές των nodes του fusion. Γνώμες ?

    Re: Davinci Resolve Updates

    Το davinci είναι για cinema editing , και κυρίως color grading.

    Αν θες ευκολα και γρήγορα εφέ, ειδικά πολλά preset κι έτοιμα transitions κλπ, τότε μείνε με το premiere.

    To fusion είναι δύσκολο φρούτο και θέλει και πολύ δυνατό μηχάνημα.
    Είναι όμως κυρίως για special effect Kai compositing...δεν είναι σαν το after effects.

    Re: Davinci Resolve Updates

    Αν εξαιρέσουμε το γεγονός οτι το Fusion είναι με nodes (ως σύστημα) ενώ το after effects με layers, γιατί λες οτι το Fusion είναι "κυρίως για special effect Kai compositing...δεν είναι σαν το after effects." ?? Με εξαίρεση το περιβάλλον που είναι με nodes (άλλος τρόπος φαντάζομαι) δεν αποσκοπεί ακριβώς στο ίδιο κοινό-εργασία όπως και το After Effects ? Το after affects και αυτό δεν χρησιμοποιείται (τουλάχιστον μέχρι πρότινος) για special effect και composition ?

    Re: Davinci Resolve Updates

    οχι δεν ειναι.... το ae απευθυνεται κυριως σε μεμονομενους χρηστες , που θελουν διασυνδεση με premiere , illustrator kai photoshop, σε μικρες διαφημιστικες, σε τηλεοπτικους σταθμους...για γρηγορο κυριως αποτελεσμα.
    Eιναι πιο πολυ για motion design ενω το fusion κυριως για 3d compositing (real 3D, οχι 2 1/2 που ειναι το AE) , κινηματογραφο και ακριβες παραγωγες τηλεοπτικες και διαφημιση υψηλου επιπεδου.

    Ειναι πιο δυσκολο να κανεις απλα πραγματα με το fusion, αλλα πιο ευκολο να κανεις πολυπλοκα compositing.



    το καλοκαιρι καναμε το πρωτο fusion σεμιναριο στην Ελλαδα, με πιστοποιηση απο την ιδια την BM.

    Θα ητααν καλο να το ειχες παρακολουθησει...
