Part of this was the reduction in resolution, but part was running it through VirtualDub. My original 5 minute video went from 760MB to 74MB. When you save, the application will process the full video based on the settings we have added. Saving is as simple as going to the 'File' menu and selecting 'Save as AVI'. The program will do a temporary processing job on the fly to show you the video. Note: if I was an expert at this stuff, I probably would have purchased professional software by nowĪt any point, you can preview the output video just by using the player controls at the bottom. I set my audio to direct stream copy ('Audio' menu, 'Direct Stream Processing'), though unfortunately I can't say whether it makes a difference for this processing job or not. Note: On closing the window, you can see the resolution rounds to the nearest multiple of 4 in the filters window Right clicking on the input or output, you can select a zoom level for each stream. VirtualDub can display the input and output streams side-by-side, but they may will probably be too large to fit on the screen. This will simplify the settings when we get to the resize step. I can't guarantee these settings as well as the ones above as I reused saved settings from prior projects, but I'll outline the main settings I used and the gotcha I ran into. To do this I will use VirtualDub to process the initial file into a lower resolution and much smaller sized file. In order to upload the video to YouTube I needed to get it a lot smaller, and I wanted to do so for the least amount of quality loss possible. The next problem is that a 740MB file would take a while to upload. My first video is slightly over 4 minutes at 1140 x 836 and came in at 760MB, although following some of the suggested settings on forums could probably reduce this without adversely affecting quality. After recording the video will be replayed for you.
