B I would like to get a feedback on this video

  1. Oct 11, 2016 #1
    This is a video on Quantum Mechanics that aims to familiarize people with general interests in physics, with some of the main ideas in quantum mechanics.
    can I get feedbacks on it, I don't have any subscribers at all, and I'd like feedbacks to know how the video could be evaluated.
    So that's why I decided to share it here.
    Thank you

    Poor sound quality.
    • The volume changes several times and is very low for most of the video. Volume is adequate from 0:35 to 1:00 but you are too close to the mic. (the 'plosives' of the speech {the "P" and "B" sounds} sound like you ar blowing into the mic.)
    • There is also an intermittent hum in the audio.
    • The tone (frequency response) makes it hard to understand. It sounds like the Bass is emphasized and the mid-range cut. Usually the reverse is easier to understand.

    Presentation: (the pacing needs to slow down some.)
    • There needs to be a little more time in between sentences.
    • There needs to be short pauses after the statement of each new concept so people have a chance to absorb and understand the idea.
      (the pacing needs to slow down some.)

    general comments:
    Some more detail and/or explanation about Waves and Energy may be useful; it's a hard concept for many people.

    In some instances, your enunciation makes it hard to understand some words.
    More voice inflection would be useful. Currently the voice-over comes across as 'droning' ("to speak tediously in a dull monotonous tone"), it seems to all run together.
    (A few hours with a voice coach or an acting coach would probably help you a lot.)

    Well, that's my humble opinion. Don't be discourged though. Around your age I had to practice technical presentations for months to get them believable. You are certainly off to a good start.

    I'm not discouraged at all, it's my very first time working with the technical part also I didn't have the time to do much refinement(It's a competition and there is a deadline) ,
    Also, the video had a maximum limit so I had to be brief at some points. Not listing the excuses I have (lol), but telling you that I knew the technical and presentation aspects were gonna end up like 3-4 on the scale of 10 maybe lol.
    And since it's my very first time, I really REALLY appreciate someone took the time to write me such a detailed feedback, So Thank you!

    But I also wanted to know whether the way I discussed the topic made sense and whether it was interesting or not, Because I made my own research about it and there hasn't been like an instructor along the way, so I wasn't only wondering whether people will understand me properly, I was also wondering whether I myself understand it to a good extent.?
    Thanks Again!

    hi Elia

    it's awesome to see you making a good effort. Video production is a whole 'nuther field on it's own, apart from the lecture aspect.
    @Tom.G made lots of good points for improvements and I'm sure if you keep experimenting with all aspects, it's going to be a
    wonderful learning experience for you. And as time goes bye, presentation and production will improve

    Hi Elia

    Just wondering how the presentation went. Could you enlighten us?

  7. Dec 29, 2016 #6
    Oh, Hello again Tom, I really thank you for asking and I'm sorry I took long but I only saw this now.

    The presentation as I told you was my submission in an online competition (breakthrough junior challenge). I didn't really get anywhere with the competition, but I met with other participants and got feedbacks from them, which was really good for me. Right now the way I viewed so many things has changed( learning about scientific ideas and presenting them)
    , and so overall I was surely benefited in some way. (Major way actually)

    I'm very thankful for everyone who took the time to review my video, whether on PF or somewhere else.

    So thanks again Tom! for your initial rich feedback and for asking about how far it went.
