Disclaimer: I do not own the Elgato Video Capture digitiser (the white USB dongle). The following information has been obtained from what I consider reliable sources.

Lossy verses Lossless workflow

It is worth reiterating that that the Elgato software captures straight into MP4, a lossy format. While this is quick and convenient (espeically with the trimming ability of the Elgato software) it reduces the ability to edit effectively post-capture, such as when making colour adjustments, denoising and re- encoding. For the best quality capture, it is recommended that a lossless process be used, such as using AmaRecTV; a guide for that is on this website here. The lossless workflow is significantly more complicated than using the Elgato software but will yield better results.

Increasing Video Capture Bitrate

One of the criticisms of the Elgato Video Capture digitiser is poor quality video. Apparently, the default capture bitrate when using the Elgato company video capture software is 750kb/sec. which by normal standards is very low. The default bitrate (and therefore quality) is able to be increased using the following procedure (provided by Elgato): 1) Quit the Video Capture software if it's running, via the tray icon. 2) Start File Explorer and enter the following path in the address bar: %appdata%\Elgato\VideoCapture 3) Edit the Settings.xml file with Windows Notepad or other text editing software. 4) Replace <VideoBitrateScale>.75</VideoBitrateScale> with a higher value, up to 3.5 maximum. 5) Save the Settings.xml file. 6) Relaunch the Video Capture software.

“Preserve Source Format” Option

This should be ticked. Analogue video should be captured in the native frame size (NTSC 720x480, PAL 720x576) and then resized as necessary later in POST.
