[Update: Keep in mind I just finished reading your article called*"What’s in a Professional Video Workflow to Convert Analog Videotapes?" AFTER I wrote the following reply below. Great article!]
Hello Lordsmurf!
Thanks for your reply!
The more I read/research all this stuff, the more it seems to be a daunting and challenging project/task to: find a lot of this older equipment (good quality S-VHS VCR; good capture card/stick, TBC; proper software; compatible OS; etc); setting it up properly; knowing*all the proper settings; the high cost of the equipment; and then hoping that none of this old equipment finally dies in the middle of the project. Reading through some of the forums I see you are quite involved and are a respected expert. But I imagine you have heard the whole story/issues/problems so many times I can only imagine you must get tired of it all sometimes. With the amount of knowledge in this forum, someone could easily*develop*many courses on the matter.
I've been thinking about this some more and might go with a balanced approach. I have about 100 tapes (VHS; 8mm; MiniDV). Some videos have more important (ie. sentimental) content than others. I'm thinking of converting the not-so-important (ie. ok quality is good enough) video content with an old video capture stick/device (I borrowed from a friend) and one of the two VCRs I currently own. For the more important videos, I'm thinking about using a professional video conversion service located in the Toronto (Canada) area (
https://www.digitaltreasures.ca/). We don't seem to have any good higher-end video conversion services here in Ottawa (Canada) where I live. I assume your professional service is very far from where I live.
The capture stick I have is the ROXIO VIDEO CAPTURE USB (UB315-E ver3* (18103050504)) with the "Roxio Easy to DVD Plus" software (which I believe you are familiar with as not being a very good capture stick).
I experimented a little with the Roxio software/hardware by capturing a 4-minute segment from a VCR tape. That produced the following .mpg file:
"My Video.mpg" 235,638 KB
The second part of the Roxio software has*enhancement/edit menus where one can trim, add titles, denoise, stabilize, color correction etc. (this part doesn't seem to work very well in that I have gotten errors in the export part when just trying to do some simple trims)
The third part of the*Roxio software does the export of it all to a number of possible different file formats, frame rates, resolution, data rate, etc. (more details below) OR all of it can be exported to DVDs etc. (I guess another question is should I be exporting to a DVD instead. But is this lower quality? In the future will it be possible to transfer over to another future better media?)
Based on what I think are some of the highest quality settings, these are the exported files I ended up with (more details listed below):
"My Video MPEG2 720 old vcr.mpg"* * * * * * *271,921 KB
"My Video MPEG2 680 old vcr.mpg"* * * * * * *471,174 KB
"My Video H.264 720 29.97fps old vcr.mp4" 246,265 KB
"My Video H.264 720 30fps old vcr.mp4"* * * 246,509 KB
"My Video H.264 480 29.97fps old vcr.mp4" 246,253 KB
"My Video H.264 480 30fps old vcr.mp4"* * * 246,509 KB
Now, someone might assume that the larger the file size, the better the quality and more information is stored. But I have a feeling this is an incorrect assumption. But why? Why did the 680 resolution file end up being larger than the 720 one!? I would assume that the original captured file ("My Video.mpg" 235,638 KB) before the export stage, should be the highest quality or at least the most 'raw' form of the video. It's the smallest file. And that this file is the version that I should always keep as an original and only play/experiment (in terms of enhancements) with copies of this original file? Is this correct?
The two VCRs (both 4-heads) I have:
- the first one I mentioned in my original post (Sanyo-2016):*
Note: this VCR also has an S-Video connection option that can be used with the Roxio Video Capture Stick as well.
- Panasonic PV-V4524S-K July-2004 (much older) (I think this is the one described on
Amazon here
https://www.amazon.ca/Panasonic-PV-V.../dp/B0001JXAMA)
After some tests, it appears the Panasonic VCR (which is 12 years older than the Sanyo) yields a better picture. Even when I use the S-Video cable with the Sanyo.* Strange.
Extra info:
The ROXIO help menu for the "File" option:
"Quality
Use this slider to adjust video quality. Moving the slider to the right improves the quality and increases the file size. Advanced Settings affect the Quality setting, so recheck Quality if you make other setting changes.
Advanced Settings
- Format/Extension: Choose between a format or a file extension. This setting affects the options in the Compression drop-down list.
- Compression: Select a codec to compress and decompress the video file. Three compression formats, WMV, MPEG2, and H.264 are available when Format is selected. If you selected Extension, you can choose from .wmv,.mp4, or .mpg.
- Frame Rate: Higher frame rates yield better quality and smoother motion, but larger file sizes. NTSC-compatible frame rates are 29.97 and 30 fps, while PAL typically uses 25 fps. For mobile devices, it is common to output video in a lower frame rate to decrease file size. NTSC is used in North America and Japan. PAL is used in most parts of Europe and Brazil.
- Resolution: Select the size, in pixels, that you want the video clip to occupy on the screen. The available frame sizes vary depending on the export format/extension. A smaller frame size (such as 480 x 270) plays in a smaller window, with lower quality than a higher frame size (such as 720 x 480). However, using a higher frame size is likely to increase video file size. You will not benefit from setting a larger resolution than the display screen supports.
- Data Rate: Data Rate represents the amount of information that is stored per unit of time. A higher data rate means less compression, better quality, and a larger file. A lower data rate results in more compression and a smaller file."
Which one of these settings below should result in the highest quality (lossless)?**I would guess the MPEG2; NTSC 720x480 (16:9) combo but I read somewhere on the internet (not sure if accurate) "Resolution of details is lower than with H.264; moving details result much earlier in blockiness." What does this mean? But then again shouldn't the original captured .mpg file be the highest quality?*
Format MPEG2
*Frame Rate: NTSC (29.97 fps)
*Resolution: NTSC 640x480 (16:9) OR NTSC 720x480 (16:9)
*Best Quality Data Rate: 15,000 kbps
*Results in .MPG extension file
*Format H.264/AVC
*Frame Rate: NTSC (29.97 fps) OR 30 fps
*Resolution: NTSC 480x270 (16:9) OR NTSC 720x480 (16:9)
*Best Quality Data Rate: 12,000 kbps
*Results in .MP4 extension file
*Format WMV(Windows Media)
*Frame Rate: NTSC (29.97 fps)
*Resolution: NTSC 640x480 (16:9)
*Best Quality Data Rate: 10,000 kbps*Results in .WMV extension file

Regarding the*professional video conversion service I have been looking at, here are the following grades of service:
Standard Grade:*$15/CDN/HR- 640 x 480 resolution- MPEG4 SD or DVD- TBC applied where necessary**
Archival Grade: $25/CDN/HR- 640 x 480 or 1920 x 1080 resolution-*MPEG4 HD or MOV- TBC applied where necessary- Videos are upscaled and deinterlaced**
Professional Grade: $35/CDN/HR- SD, 2K or 4K resolution- ProRes, AVI & other formats- TBC applied where necessary
- Teranex processors to upscale video up to 4K resolution, switch between aspect ratios and frame rates, denoise and deinterlace recordings.
- Up to 10 bit colour depth. Depending on the source material. Can capture video at up to 10 bit per channel colour depth.
- ProcAmp adjustments. Brightness, contrast, saturation, hue, black level & sharpness adjustment is done on a per tape basis to achieve best results.
- Timecode and Closed Captioning. Original source timecode, closed captioning and teletext data is retained and can be left encoded into the file or provided as a sidecar file.
- 3:2 cadence removal. If applicable to the source material, 3:2 cadence will be removed for smooth playing video.
- Digital transfer pipeline. Throughout the transfer process, they switch from analog to digital pipeline at the earliest opportunity to keep the amount of time spent in analog mode to a minimum. Digital tapes are never taken into analog realm.
- Any standard file output. In addition to common file formats such as ProRes, DV, H.264 and others, can provide any other required file format.
I'm thinking Archival Grade is probably sufficient. Professional maybe more geared for the business customer?
Any other thoughts/advice/opinions are much appreciated!
Thanks!
Cheers,
Dett

Ahh...I think I answered one of my questions.
I think the "My Video.mpg" 235,638 KB is the best version in that it probably has been captured at the ultimate(perfect) data rate (~7,500 kbps) (ie. no wastage), whereas the "My Video MPEG2 720 old vcr.mpg" 271,921 KB which was set at 15,000 kbps is unnecessarily 'bloated'?
