Hi there,

I've been reading through forum posts for a while now trying to figure out the best way to do this, but I'm feeling overwhelmed because so much of the advice on here seems to conflict with other people's advice. So, I decided to just make my own post. At the very least, writing all this out might help me organize my own thoughts.

I'm in the process of transferring VHS tapes, VHS-C tapes, and Hi-8 tapes to digital. I'm doing all my Hi-8 tapes first, so that's what this post is dealing with. I'm using the Hauppauge USB-Live 2, with an S-Video cable, to capture and I'm using AmaRecTV with Lagarith to record to lossless avi files. Everything's good up to this point.

Now, my goal is to take these source recordings, deinterlace them, denoise them (with Neat Video for VirtualDub), crop out the scan lines at the bottom (VirtualDub seems to be fine for this), improve the audio quality (if possible), and compress them to mp4 files so they can be easily shared over the internet. I would like to get some of them on DVDs later too, but that's secondary to the mp4 files.

Here are my questions:
1. What order should these things be done in? Should I be saving a new version of the file after every processing stage? (As opposed to telling VirtualDub to deinterlace and denoise at the same time, for instance)
2. What's the best program for deinterlacing? I saw someone say VirtualDub's deinterlacing isn't the best, but I don't see anything wrong with it.
3. What's the best way to improve audio quality? Someone recommended Audacity, but I find it hard to work with.
4. What's the best program and settings for compression and conversion to mp4? I've tried this so many different ways and it always comes out sort of disappointing. I feel lost when it comes to selecting bitrates and such. I'll take somewhat large file sizes if it means decent quality.

I'm not a guru, so this "advice" that really isn't advice, I suppose it's better than literally nothing. I've come across a general bitrate recommendation here (though I think it's for uploading best to Youtube):

720p = 2000kbps - 4000kbps
1080p = 3200kbps - 9000kbps
1440p = 8500kbps - 13000kbps
4k = 13000kbps+

I know some people use high quality compression in Hand Brake. I suggest this because no one else posted anything. Better than nothing, right?

Give YT as much bitrate as you can stand. I often upload my VHS captures to YT at at least 15kbps and I upscale to at least 1440P (ie 1920x1440), not because it improves the quality but because if you give YT 1440P, it will use the better VP9 encoder.

The OP had an answer where he first posted: https://forum.videohelp.com/threads/...ess-avi-to-mp4

For YouTube upload there is no need to encode, the lossless capture (restored and) upscaled to 1440x1080 for 4:3 material can be loaded without compression.

On the other hand, for low resolution SD material a h264 compression at low crf does not hurt. A comparison here: https://www.digitalfaq.com/forum/vid...html#post79818
