Hello people! Ofesad here from Argentina.
In my search of a TBC, I came across of this brands: Digiwave and Vidicraft.
(Seems like Digiwave resells Vidicraft; or that Vidicraft is a cheaper version of Digiwave).
Since I am unable to find any specific information about'em I wanna ask if anyone has heard of them?
I am interested in two models, here are the specs (the documentation is in spanish, so I translated it):
VIDICRAFT V8i
Norm converter, timebase corrector and transcoder.
Closed caption signal processor.
- Norm converter of TV PAL, PAL N, PAL M, NTSC, NTSC 4.43 and SECAM .
- Spatial and temporal aperture interpolator of 8 points, 2 fields, 4 lines.
- Adaptative, high performance Digital comb filter of 5 lines. 5.5 MHz. bandwidth.
- A/D and D/A conversion and 10 bit processing.
- Luminance and Chroma gain control, black levels, hue (NTSC) and horizontal enhancer .
- Two inputos and two outputs of composite video.
- Closed caption signal processor with input decoder and output encoder with line selector.
- Front panel with iluminated display and keyboard (Translation note: it actually says keyboard, but I thing they meant the keys), allowing diferent characteristics, options and functions selection.
- Presets can be stored in non-volatile memory.
- No input signal response selection: last valid field, color bars, black field.
- Color bars and black field generator.
- Versión V8i-2 comes with two independent converters in one rack unit
TECH SPECS:
AD conversion | 11 bit, 27 MHz (2X oversampling) | DA conversion | 10 bit, 216 MHz (16X oversampling | Processing | 10 bit, 4:2:2 | Interpolation | Apperture of 8 points, 2 fields, 4 lines | Analog inputs | PAL, PAL N, PAL M, NTSC M / J / 4.43, SECAM | Analog output | PAL, PAL N, PAL M, NTSC M / 4.43 | Conversion | Bidirectional: 525/60 a 625/50 y 625/50 a 525/60 | Comb filter | Digital of five lines, adaptative, for PAL, PAL N, PAL M y NTSC M / J | PERFORMANCE
Luminance bandwidth | 5.5 Mhz. | Diferential gain | <1.5% | Diferential phase | <1.5% | Signal to Noise ratio | > 60 dB, balanced |
and here's the one I am most interested:
Digiwave DMT-150i
- Time-base corrector, frame synchronizer and PAL, PAL N, PAL M, NTSC, NTSC 4.43 y SECAM transcoder.
- 5lines high performance Digital comb filter: bandwidth 6 MHz.
- A/D y D/A 12 bit conversion and 10 bit processing.
- Digital noise reducer with recursive frame filter
- Input and Outputs: composite video, de Y/C (S-Video), y digital series 270 Mb/s (SDI)
- Horizontal and vertical (aperture corrector) enhancer, adjustables.
- Genlock input with digital settings and "loop-through".
- Front panel with iluminated display and buttons, allowing access to diferent characteristics, options and functions selection.
- Preset storage in non-volatile memory, for each input.
- No input signal response selection: last valid field, color bars, black field, swap to Video Input 2 or show stored frame.
- Test signals generator.
- Storage and capture of full frame images.
- Remote control via Ethernet
General Specs
A/D conversion | 12 bit, 54 MHz (4X oversampling) | D/A conversion | 12 bit, 216 MHz (16X oversampling) | Processing | 10 bit, 4:2:2 | Interpolation | 8 point, 2-field, 4-line, with conversion aperture selection | Inputs | PAL, PAL N, PAL M, NTSC M / J / 4.43, SECAM | Outputs | PAL, PAL N, PAL M, NTSC M / 4.43 | Conversion | Bidireccional: 525/60 a 625/50 y 625/50 a 525/60 | Comb filter | Five-line adaptive, for PAL, PAL N, PAL M and NTSC M / J | Noise reduction | Frame recursive adaptive for luminance and chrominance | Frame synchronizer | Infinite window | Performance
Luminance bandwidth | 6mhz. | Phase diferential | < 0,7 % | Gain diferential | < 1% | Transitory response | < 0,5 %, K2T factor | Signal / Noise ration | > 65 dB, weighted | Luma/Chroma delay | < 10 ns | SC/H phase | < 3º |
What are your impressions, at least at first glance?
Feel free to comment.

The Digiwave is a rackmount unit, and most rackmounts have issues with VHS. I'd have to test it. Just based off what I see, doubtful it'd be as good as DataVideo, Cypress, and a few other select units. Most are more trouble than they're worth.
Ditto for the Vidicraft, just another rackmount. (And BTW, this is NOT the same company that released the Vidicraft boxes in the 80s, as that company became Studio1, and later SignVideo.)
Do both have s-video, or just the Vidicraft.
Both look familiar, but I can't quite place it. The tiny buttons, rack plate design (oval screw mounts), and LED screens are a giveaway,
I almost think that both brands are just rebadges of something else.
Based on this lin, Vidicraft is a Digiwave sub-brand: https://www.digiwave.com.ar/download...8i_en_2_00.pdf
Don't click the link, read the URL: digiwave.com/vidicraft
If you get either of these, understand you're gambling. Budget accordingly.
And even if it "works" for you, it may not for others, so be careful with advice. I've seen that way too many times over the years, when it concerns these sorts of TBCs.

Sadly in Argentina there aren't many options.
Datavideo has distribution here but I haven seen any store with TBC's for sale.

Yeah, sadly most rack TBC's look the same or have the same components design: buttons, knob and screen.
These remember me more of DPS TBC's.
I also noticed that the sites have references between each other. Also, the telephone of Vidicraft is the same in Digiwave. And in the digiwave website they have "special offers" of Vidicraft products.
BTW the Digiwave site has an English version: https://www.digiwave.com.ar/1005.html

Yeah, I know. I would call tomorrow to check the prices and report to you, SmurfLord.
I saw one used for 70usd.
Also there's a Datavideo TBC (TBC3000) for sale here in Argentina (used but NIB) for 150usd.
