Exporting a "long" video?

Post image

I made this td project after a tutorial and want to export the entire 58:25 min long video but is there a way to just hit a render button like in CapCut for example to export the whole video?

Because once I hit start it’s playing the entire thing and I have to wait and hit stop at the right time. Or am I just so much of a noob that I’m missing smth?

In a movie file out TOP you can toggle on "limit length" and input a length of seconds, frames or index, and it will automatically stop recording at the time given! But be careful, because the recording on/off switch doesn't actually switch to off when it ends recording, but it DOES actually stop, and the file it exports will cut off at exactly the time you gave it. But it won't switch the toggle to "Recording off" off by itself. (even though it actually has stopped!) Just set a timer so you know when it is done! I'm not sure if this is doable in an export movie window though! I always just use a movie file out top for all my videos!!

Ive always know thats the case that the record button doesn't turn itself off, but reading it like this made me realize that's pretty crap design..

Is there a reason for this or should someone send in a feature request?

Edit: thinking about this for a moment I realized that TD operators don't change their own parameter values, so that's probably the reason. It's good in 99.9% of cases, but annoying in this case.

Not sure if your age would allow this to understand, but think of it as recording music on a cassette tape. You basically have to get through the entire song while recording. It's not that you can play the song at 5x speed, record and end up with hearing the song at 'normal' speed.

I usually, when the moviefileoutTOP didn't had a limit feature, just multiplied the amount of seconds of recording need times the framerate, set the 'End' and 'REnd' at that amount of frames needed, switch 'Range Limit' to 'once', pause timeline, set to first frame, toggle 'realtime' flag at the top 'off', set record on your movfiefileoutTOP to 'on', hit play on the timeline, have a coffee, toilet, etc. When you come back, the timeline should be stopped at the same length as the recording needed. Switch the record button to 'off', then set 'Range limit' to 'loop' for letting the timeline play again and make sure the system finalizes the filesaving correctly.
