Slow down videos for easier listening, configure skip time

It might be possible to ease listening and writing down/translating words if there was a way to slow down playback speed.

I fear this might be technically impossible though.

It would be useful if the user could set the seconds-to-skip number. 8 is often too much for me for example.

    Thanks for this suggestion. We'll think about this and see if we can come up with a solution.

    i agree with the original poster: having 8 seconds with fast talkers is a lot of words.
    a small configurable slider, or textbox would be fantastic.

    I use Advanced feature (Tab control) to stop start stop start because I find it easy. Taking more time, but results in best accuracy, eloquent flow and easy synching is creating the transcript separately from the audio only. By this method, one can pay attention to selecting and pasting "just enough" into the lines.

    Alan, I also use the Advanced feature. Nevertheless, even so, the skip back time is set at 8 seconds, which, as qubodup and thorsten82 pointed out, can be way too long with fast talkers. If skip back were 1 second, as it is on other captioning platforms, people could repeat it if they wanted to skip back more.

    qubodup, re slowing down the video, until Univsubs possibly comes up with something of the sort, here's a DIY work around: extract the audio of the video (e.g. with MPEG Streamclip), then use Audacity's labels to transcribe it or the parts that are difficult: Audacity's transcription toolbar allows you to adjust the reading speed without modifying the video, and it is free multiplatform software.

    Audacity's labels:

    Claude, I've learned to set controls for zero skip back time with Advanced
    Tab as control stop/start/stop - way way easier, more direct. Best best AK

    Thanks, Alan: but what about when you need to skip back, e.g. when your connection is slow and hitting tab to stop does not stop the video immediately? I've had that issue when working with a wobbly wifi connection.

    If I understand you, you seek the best way to edit closed caption text
    within, e.g., UniversalSubtitles online application.

    When I am working and must correct a caption I just created, I click on
    that caption box, edit and it's done.

    Wobby, weak, or unreliable WiFi creates problems because data packets must
    be sent and received.

    For various reasons I prefer to
    1) obtain the audio offline;
    2) create text offline; and
    3) copy-and-paste the text to be synchronized.

    Doing the work this way makes more easy and "graceful" the
    UniversalSubtitles step of synchronizing.

    Reliable internet connections, extremely short or small files, and/or tight
    deadlines can be reasons for doing everything online.
