1. Thanks for the video sir!

2. Been playing around with blender a bit, lets you do a fair amount of things, but I was really shocked at the lack of (mostly) audio editing. I know the main program is about modeling, not the video editor, but even still…

3. oh my god thank you, this is so helpful

4. I see that this videos are quite old but just wanted to let you know that this tutorials are done very well and thank you for that!

5. Yeeeeaah… see ya in few years Blender after you put your shit together…

6. To set the start frame in 2.8 use ctrl-home
   Toset the end frame in 2.8 use ctrl-end

7. damn i'm late to the party. i just discovered blender is also a video editor. i'm officially dropping vegas. GOOD RIDDANCE. i hated that program for every second i was forced to use it

8. thank you soooo much… I'm a beginner and just finished about 10 days of PNG rendering and not so happy with the speed, so this is REALLY helpful.

9. Can you do an updated version please?

10. When I change the pitch, it doesn't make the audio shorter, it only increases the pitch

11. Thank you AGAIN!

12. man you rock <3

13. It no longer works. When I do the Speed factor at one and the Multiply speed at 4 all it does is play really slowly and when 1/4 way the strip it starts with the next one.

14. So when I go to render the video I'm making it cuts the video short. I'll retry it but for some reason when I try to get it to work it just throws the whole thing off. And yes I set my end frame to the end of the greyed out portion. Please help.

15. Just something i came up with: Whenever changing the speed, i put the video at frame 1 in a higher channel and i hit page up to go to it's end, then i click on the current frame down below (that controls the green header line) and then i multiply it to the reverse of whatever i set my speed to (for instance if i set my speed to .5 then i would do "frame * (1/.5)") and then i don't have to search for the moving frame because i will be sure that's where it ends. Let me know if that makes sense to you guys.

16. Fantastic video. I've found this whole series tremendously helpful. I do have a question about this process, however. I will attempt to describe here what I'm trying to do with Blender, and the issues I'm having with it.

    I'm trying to make videos for my channel that feature me building in the Sims 4. This can be a slow, tedious process, and so I run the game footage in 4x speed. I usually scrap the audio strip, as I record a separate commentary for the video, so that my voice doesn't get sped up with the game footage. I've tried this two ways so far, and neither are ideal, so hopefully, you'll have some tips to help me make this process more efficient.

    The videos in question are on my channel now if you would like to check them out and see for yourself what these issues look (and sound) like in the final video.

    The first video, entitled "Newcrest Dog Park," what I did was discard the audio from the original footage, then recorded separate footage of me doing my commentary which I then laid over the game footage to make the finished product. I watched it right there in the Blender preview window while I did the commentary. I found out, however, that when I imported that commentary video into my project, it was several seconds shorter than the video itself, and the audio wasn't syncing up quite right. Now, I band-aided this problem with a fade in at the start and a fade out at the end, which helps hide my commentary video stopping before the full video is really over. Also, on a side note with this one, the fade in and fade out ended up kind of wonky, which I think had something to do with trying to fade over multiple video strips.

    The second video, entitled "Isla Spauna," is much better than the first in terms of general quality, and specifically, the audio sync is fixed (there is some echo in the commentary audio, which was an issue with the settings I was using, and has since been fixed, I believe), but it was a very long process to produce the end result. Basically what I did was to start the same way, I discarded the audio strip, sped up the video strip to 4x, but this time, instead of watching it back from Blender and adding that track, I rendered out the silent footage. I then set up OBS Studio (which I use to record) to play the file when I switched to the specific scene where I would be watching it. The end result is clearly much better (even though by this point, it was late at night and I was so over the whole process that I didn't even add my simple fade in and out), but it was extremely time consuming, and frankly, pretty annoying.

    Which finally brings me around to my actual question: Is there a way in Blender to streamline this process, perhaps add commentary audio directly from Blender, or some other trick where I'm not spending forever rendering two versions of the same video?

    Any feedback on this would be most appreciated. Both of the videos in question are in the "Sims 4 Builds" playlist on my channel.

17. My gopro films in sections and I need to join them together. The part I want to speed up is spanned across multiple clips, is there a way to join them together so I can speed up all the clips?

18. That was a pain in the Neck!

19. i like how he synced the video and audio but the video and audio arent even synced in the tutorial hah

20. potty training tutorials like these make the "Mount Everest Learning Curve" of Blender more "wheel chair accessible" for retards like me. Mom i'm done …………. come wipe my bum!

21. Its helpful to turn on Draw Waveform on the audio strip so that you can visually locate sounds and pauses in the audio.

22. how can I increase the speed to 24fps OF MY PREVIEW when I play the triangle below the video sequence editor?

23. That was super helpful thank u so so much ❤

24. You're an idiot!!!! Speed up speed and get shipmunk voice?? Are you kidding? And you say it's perfect that way??? YOU STUPID!!! DAmn time lost here ssshhhkkkkkkk

25. I have a problem. I'm trying to render a video with sound, but the audio doesn't render for some reason. Can somebody help me?

26. Is there a way to make audio clip slow, but without pitch?

27. Hey Mike thank you for your tutorials!!! You helped me a lot using Blender as video editor in the making of this video https://youtu.be/-1xs3lnEEIU . Hope to see some tutorials about transitions and advanced masking in the future.

28. This 11min tutorial on video/sound speed makes me never EVER want to use blender

29. Hi,

    How can we reverse a video strip on blender??

30. Super
    Thank you
