Hi,
I'm attempting to digitize and improve on a recording of a music recital that spliced from 3 different cameras/angles into 1 continuous 2 hour VHS tape. I was hoping for some insight on how to approach filtering 3 different angles intertwined into a 2 hour tape and specific filter settings for each camera angle. I attached a short clip which happens to contain all 3 camera views which is representative of the 2 hour recital that switches between the 3 views for each song.
The capture was done with JVC HM-DH40000U (all NR settings OFF) via S-video to ATI AIW 9700 PRO AGP using
VirtualDub in WinXP with
HuffyUV (filtered results saved using Lagarith)
VirtualDub was used for the original capture. I previewed the histogram before capture and boosted the brightness (155) and lowered the contrast (100) since it was clear the entire tape had extremes at both ends of luminosity.
Using VirtualDub, I used:
Gradation Curves filter (Y/U/V mode) [exported the settings, attached the .amp file]
Color Mill Saturation (Dark -13, Middle -20, Light -70)
Brightness/Contrast (Bright -3%, Contrast 106%)
Color Equalizer (R -2, B -4)
Dynamic Noise Reduction (12)
Crop/Resize with letterbox
Additionally, I blended the second cut (overexposed with yellow color cast) with internal HSV filter (Hue +2, S -69%, V -35%)
I elected to blend filters because I thought splitting and reintegrating all the different cuts would be extremely tedious. Though if that is the recommended workflow, I'll roll up my sleeves and get to work
I didn't intend to use so many filters. I just played around with a bunch of filters to try to make incremental improvements over several days. And when I attempted to replicate the changes in another existing filter in attempt to consolidate into few filters, the result often was worse.
I've been reading up on AVIsynth, haven't tried it yet as I'm not sure how to approach using it on a capture than switches between 3 scenes that need different settings. That's why I stuck with VirtualDub and used blended filters
I'm looking for suggestions on:
1) Specific alternate filtering settings
2) Alternate workflow to address correcting 3 different camera scenes interspersed in a 2 hour video
3) How do I remove that streak frames 87 and 88? It happens frequently in the first third of the capture and infrequently in the last 2/3rds
I've attached sample from original capture, my multilayered virtualdub filtering attempt, and the gradation curves export file (my other filter settings are written above)
