There isn't really enough information to go on.

What Camcorder are you using?

I suspect you may have an aspect ratio setup wrong or video mode (PAL or NTSC or sometimes it says video lines) and although the video file uploaded to youtube was full HD. I don't believe that capture box is helping your production (it can't do full HD).

It's designed to move from VHS to Computer, so is really a basic PAL or NTSC capture device. So you can't expect too much from it. (From what I saw it wasn't set right, but I don't know what right is for your camera it just needs to match).

So from that limited information.. I suggest getting a Full HD Camcorder (if you are not already using one, it would have a Mini HDMI port usually). Then getting one of these:

It will take a nice digital HDMI signal from the camera and if the rest of your hardware is up to the task (You need USB 3, decent CPU/Video). You should get a picture into VMix that is as nice as what the camera can do. If you do not have HDMI on your camcorder, get a new one. They are pretty cheap these days.

The reason I recommend the Magewell capture device is not because it's the cheapest. It's got an in built scaler and works without drivers (using a universal webcam driver in Windows). Perfect for a Pro or some who doesn't really care about interlaced/non-interlaced and all that video speak so much. The scaler does it's best to make things GO even if you are not using the perfect mode or frame rate right through.

If your camera is 720p it will be a 16:9 aspect ratio camera.

I have not used your capture device, but go for a 16:9 and ratio here: https://pacoup.com/2011/...of-true-169-resolutions/

Green ones are more common resolutions.

So 640x480 is a 4:3 ratio. (Not widescreen and therefore wrong so it has to add black areas/bars or stretch the picture unevenly, both not ideal).

You want the highest resolution your capture device works with, that is a 16:9 ratio. Maybe 768x432 if that is an option, it should at least do 640x360 I hope.

16:9 Resolutions are here https://pacoup.com/2011/...of-true-169-resolutions/

I still recommend getting a better capture device. Even though your camera is HD (720p) and not Full HD (1080p). You can get a HDMI capture device and then capture at 720p. (which is 1280x720 pixels)

You will have a much better result. Then your next upgrade could be the camera (but upgrade your capture device FIRST).

So your current camera has "Mini HDMI connection for viewing your videos on an HDTV". That's what you want to use a capture device that can accept that output. Mini HDMI can be converted to full size HDMI with a cheap cable.

On Camcorders... seriously think about a 1080 50i capable camcorder. They exist at low budgets, they may not have superior low light, stabilization and zooming performance in the cheaper ones.

So $200-$400 will get something better and it will be noticeable if you have the capture equipment first. I'm not suggesting a $1,000+ camera as I imagine you are on a tight budget.

AverMedia make some cheaper capture devices. They work well for most people (are well tested), but do not have a video scaler inbuilt and do need drivers that come with it of course.

If your using a computer with a free PCIe Slot and not a laptop, they are a decent choice.

It should be around $150 or less depending on the model.

Check http://www.vmix.com/soft.../supported-hardware.aspx for the various AverMedia supported capture devices and watch for a special.

Anyway that's assuming a "small" budget suddenly appears. Next week your production could be the next Internet sensation :)

In the US, most USB capture devices can capture Standard Definition NTSC video at 720x480 as the best resolution - that is what you get out of the composite cable. Then the camera input configuration settings (the cog in the lower right corner of the input) adjust the "Aspect Ratio" settings to get the proper aspect ratio. You may need to focus on some squares or circles to make sure you have the aspect ratio set correctly.

For not too much money, you could purchase a Blackmagic Intensity Shuttle to capture the HDMI feed of the camera directly. That will significantly improve your image on the laptop, but may not do much for the webcast depending on your settings.
