How to convert VHS videotape to 60p digital video (2023) - OBS software
https://www.youtube.com/watch?v=tk-n7IlrXI4

This page shows you how to use the Amarec software to get excellent quality, uncompressed game captures. I’ve had many issues with this software over the years and sometimes it won’t work at all with Windows 10. If you’d like to try it, use v3.10 or higher, as I’ve seen weird bugs with other versions…including a bug that recorded at 30fps, even though it was set to 60fps!

Which Version of AmaRecTV to Use
You can obtain AmaRecTV 3.10 from this VideoHelp download page. There are newer versions of AmaRecTV, but you SHOULD NOT use them.

Intensity Pro 4K supports various video signals, so it cannot be used unless the following capture card side confirmation and settings are completed

e color format was not supported, and the preview image was flipped upside down.

Amareco TV 4 also supports Intensity Pro 4K RGB capture, so you can record and preview in RGB as well as YUV. With Intensity Pro 4K, two video source filters (capture devices in Amareco TV) are registered, and the color formats that can be used are slightly different. ・Blackmagic WDM Capture YUV10bit YUV8bit RGB10bit RGB8bit・Decklink Video/Audio capture YUV10bit YUV8bit RGB10bit Blackmagic WDM Capture Blackmagic WDM Capture can capture in RGB32 (RGB 8bit) or R210 (RGB 10bit). Here we will explain the case of RGB32 (RGB 8bit). R210 is the same as Decklink Video Capture (in terms of Amareco TV), which will be introduced later. The YUV system is the same as the current AmaReco TV, so it will be omitted in this article. As a specific operation, it is passed to the custom filter of Amareco TV as ARGB with alpha channel (the content is the same as RGB32), so we responded by rewriting the subtype to RGB32.

The contents of the frame data are probably the same, so only the header information will be rewritten. AmaReco TV does not perform any unnecessary conversion processing.

Decklink Video/Audio capture RGB32 (RGB 8bit) cannot be used here. Only for R210 (RGB 10bit). The YUV system is the same as the current AmaReco TV, so it will be omitted in this article. AVI Decompressor converts R210 (RGB 10bit) to RGB32 (RGB 8bit) and operates. Therefore, both the content displayed in the preview and the recording will be of RGB 8bit quality. which one should i use? Decklink Video/Audio capture definitely performs 10bit-8bit conversion, so if the video signal is 8bit, this process is useless. In a similar case, using Blackmagic WDM Capture would look cleaner and safer, but it's hard to say since the conversion process may be done inside the video source filter. I think it's okay to use either one, since they can be used in the same way. However, it is troublesome to explain both and check the operation with both, so I use Decklink Video/Audio capture although there is no particular basis.

The "Video Input" item displayed at the bottom left is important.
The content displayed here is currently the format that can be used with Intensity Pro 4K, so this content and the AmaReco TV settings must completely match.
In the example above, you can see that the HDMI terminal is used, the image size is 1280x720, a progressive image, and the frame rate is 59.94fps.

Also, there are two types of video signals: RGB and YUV, but there is no way to check which video signal is currently being captured. You need to check the video settings of the device that outputs the video or set it explicitly.


Correspondence table between main video signals and AmaReco TV4 settings

720p 59.94
If the video signal is YUV: "*w= 1280 , h= 720 , fps= 59.94 , fcc=HDYC, bit=16"
If the video signal is RGB: "*w= 1280 , h= 720 , fps= 59.94 , fcc= r210, bit=30"

1080p 59.94
If the video signal is YUV, "*w= 1920 , h= 1080 , fps= 59.94 , fcc=HDYC, bit=16"

in the case of AmaRecTV, all you have to do is select "Blackmagic WDM Capture" . w=1920, h=1080, fps=60.00, fcc=RGB , bit=32We have confirmed that full range can now be captured correctly.

do your deinterlacing later after capturing. The best deinterlacer by far is QTGMC in AviSynth. It's a pain to get set up and learn but well worth the effort. I believe that Staxrip has added it recently. A distant second is Yadif. It's available in several other programs including VirtualDub2, ffmpeg, etc.

Do these settings look good in AmaRecTV for capturing Video8 and Hi8 tapes?
https://forum.videohelp.com/threads/384 ... -Hi8-tapes


capturing with AmarecTV to a lossless codec - Lagarith, Huffyuv, MagicYUV, UT Video etc. - make any adjustments and apply any filters in either Virtualdub/Virtualdub2 or Avisynth, and then use Handbrake or Vidcoder or Virtualdub/2 (or HC Enc etc.) to encode to final format.

Jason Scott —
What are the most efficient settings in virtualdub for high quality capture?

Here are some settings in VirtualDub that can result in high-quality captures:

Video compression: Use a lossless codec such as Lagarith or Huffyuv to capture the video in its original quality.

Frame rate: Set the frame rate to the same as the source material. For example, if the VHS tape is recorded at 30 frames per second, set the frame rate to 30.

Audio compression: Use an uncompressed audio codec such as PCM for the best audio quality.

Video resolution: Set the video resolution to 720x480 for standard definition (SD) material, or 1920x1080 for high definition (HD) material.

Video filtering: Use filters to deinterlace the video and remove noise if necessary.

File format: Save the captured video in AVI format, as it is a widely supported format that retains high quality.

Note: These settings may vary based on your specific setup and the quality of the source material. It may be necessary to experiment with different settings to achieve the desired result.
