Is splitting a video for export a good technique?


New Member
Currently, I'm making a video that I intend to upload to YouTube. I used After Effects and Premiere Pro for this. Since it's a video that's almost 2 hours long, the export takes me about 16 hours according to my PC specifications:
  • Installed physical memory 8.00 GB.
  • 11th Gen Intel(R) Core(TM) i5-1135G7 @ 2.40GHz, 2419 Mhz (I'm using the integrated GPU)

The first question is, is it normal to have such high export times? From all the video tutorials I've seen, I haven't seen export times as high as mine, but I suppose it's due to the added effects and the length of the video.

Exporting for 16 hours straight is very inconvenient for me because I plan on continuing to upload videos, and if I have to leave each video for 16 hours or more, that means the laptop battery will deteriorate, and I also use the computer for university work. The solution I've come up with is to slice the video into several parts, export them, and then join them with ffmpeg, which I understand does not perform rendering (or something like that).

When I did it, it came out correctly, and there were no issues. The second question is that I would like to know if this technique has a name and how to do it correctly. I would also like to know if there are any disadvantages to doing it this way. I exported in H.264 at 1080p and 24 fps, and then I joined them, but there may be a better way to do it.

I'm asking this question because before attempting it, I searched the internet and didn't find much information about this technique. The information I found mentioned that there would be problems between frames because a frame contains information about its next frame, but I found that it worked for me, and in case of problems, the cut can be made just at scene changes so that it doesn't affect much.
