    1-hour Video

    by Yann R

    I like InfoQ.
    I like brief information, introducing a more detailed content, why not in a video way.
    I love text because you can read through paragraphs very quickly. There are subtitles.
    I hate 1-hour videos, waste of time.

    I think its quite reasonable to request the option of just the presentation slides (shown below in the video) as an option for those who dont have the time to sit through an hour.

    I m unable to watch any infoq presentation (the video stream never be smooth on my end - home or office). So providing slides, subtitles or offline videos is better.

    He didn't reasonably ask for a slide or video download option. He stated that hour long videos are a waste of time. Many of the videos here are that length or longer, so there must be some demand or they wouldn't keep posting them. I replied in a similar tone. I agree that additional downloads would be a good thing. However asking sincerly rather than belittling someones work would be a better way of going about it.

    It would be nice if the presentationa could atleast be downloaded.

    We do have plans to release MP3 copies of most of the already posted presentations and all of the future ones.

    As for the slide downloads, yes it is a reasonable request but we don't own these slides and it would require special permission with each of the speakers to get copyright permission. In the meantime if anyone wants the slides, feel free to ask the authors.

    The intention of these videos is to bring out knowledge from conferences. For all those people who couldn't make it to a conference to watch these, you have them online here on InfoQ.

    We cannot change the way the presentations are delivered at the conference, so one hour it will have to remain. :)

    Viewing them is optional of course.

    I find that I don't have enough time on my hands to catch up with the videos. Are there any plans to release them in a video podcast format. Having them on my iPod for commuting would be a huge bonus.

    Unfortunately we don't plan to do that. It would be far to complex on the legal front with authors, and it also wouldn't support our core objective of making InfoQ the 'goto' place. Also, I have no idea how the video feeds and slides could be seen together in such a format, so our only distribution plans at the moment are MP3 audio.

    Could you provide an option to directly move to a particular slide like you provide an option to directly move to a question for an interview?
