Veyra User Guide-04-The Most Problematic Capture Cards in the Group

Data source: the complete chat logs of Veyra community groups 1-4, 2026-09-13 ~ 2026-10-05

Counting basis: number of issue occurrences (repeated discussion of the same issue counts each time), issue types, number of cross-group cases, official / author statements

[Conclusions at a glance] ① Most problems, most discussed: AVerMedia GC573 ② Most concentrated single issue (8bit HDR banding, confirmed): ASUS TUF 4KPRO ③ High rate of quality problems but a small user base: UGREEN (CM700/CM701), HAGiBiS, low-price no-name cards ④ Hard spec flaws: AVerMedia GC575 (a flagship that cut 4K60HDR), Kuhaomi 26P (2K only) ⑤ Price change reminder: the ASUS 4KPRO has gone up in price, and "clearance was a steal" is now history — any related "value" assessment no longer applies (see section 2)

1. First place: AVerMedia GC573 — the most problems (the most types of issues + called out by the author)

[Issue list (across 4 groups)]

1. HDR red tint (the most famous compatibility bug)

• Aitor's test: "The left one is the gc573, the right one is the gc553g2, and the 573 is clearly redder"; "in HDR, dropping red saturation by -50 makes it look normal, but then the color banding is unbearable"

• Cause (analysis): "The GC573 can output P010 pixel data for HDR, but the DirectShow source filter doesn't pass HDR/WCG metadata correctly" — it takes a third-party tool to fix (the open-source project directshow_metadata_injector_filter)

• Official workaround: every time you boot, open OBS first (P010 + REC.2100 PQ) and then open Veyra (the method pinned in the group)

• The author admits: "There used to be cases where some capture cards had a red HDR tint… noted in my little bug book"

1. Color banding / 8bit only

• "AVerMedia told me their 573 is only 8bit" (En tierra checked with the vendor)

• "From what I see, the 573 only supports 10 in p010 format; every other format is 8"

1. Vertical streaks in bright areas on PS5 (a YUV420/422 conversion issue) — requires setting the PS5 to "HDMI transfer speed -2"

2. White specks / blue specks issue ("there's a lot of feedback about the 573 hdr white speck problem"; after rolling back the driver the white specks turned into blue specks)

3. MSI AMD motherboard 53-frame / 33-frame / 15-frame issue (multiple cases, see motherboard compatibility)

• "Paper specs are strong, but MSI boards + AMD have a lot of traps; at this point I really can't recommend it"

1. No VRR support ("the 573 has no vrr, I bought it and then returned it")

2. A roundup of small compatibility problems (Hi's summary): "The 573 has poor compatibility and lots of small problems; there's coil whine, PCIe sometimes hangs and you have to reseat it" "the 573 has lots of small problems, it's luck of the draw"

3. Crash case: 4070Super + "after connecting it shows the picture for a moment and then crashes outright"

4. Latency anomaly case: "the 573 has 140-something latency, worse than UGREEN" (units of the same card vary a lot, which comes down to the motherboard / platform)

5. Unusable without the driver installed (needs Assist Central Pro); officially "risers are not supported"

6. Poor cooling: the backplate gets hot, "adding a 4cm fan is recommended"; "it throttles when it gets too hot" [What the author and veteran group members said]

• The author, 2026-09-26: "Stop buying the 573, buy something else — groups one and two are full of problems"; examples: "like capture only at 15fps, or hdr turning red"

• Hi: "even the previous-gen 573 can capture 4k60hdr" "the 573 has lots of small problems, it's luck of the draw"

• But on the other hand: it's still one of the two big choices for "4K60HDR maxed out" (the other is the Elgato MK2), with extremely low latency (5ms in same-screen testing), good color (once fixed) and a reasonable used price (1100-1400) [Verdict] The GC573 is a classic "high ceiling, low floor": tuned right it's the latency king, tuned wrong it's all black magic; the root of its many problems: 8bit + an old-generation HDMI2.0 design + HDR metadata compatibility + sensitivity to the motherboard's PCIe environment. [Advice for GC573 owners]

1. Install the official driver / Assist Central Pro and check the firmware before use

2. For the HDR red tint, use the OBS workaround or just play in SDR (it's very stable in SDR)

3. MSI / AMD platform users should do their BIOS homework first; if it won't hit 60 frames, check the PCIe bandwidth first

4. HDR colors being wrong on every boot is a "congenital problem"; if that's too much hassle, sell it and get a G2 / mk2

5. Add a small fan for cooling; PS5 users, remember HDMI transfer speed -2

---

2. Second place: ASUS TUF GAMING CAPTURE BOX-4KPRO — the most concentrated single issue

[Core issue: 8bit HDR color banding (confirmed)]

• 张威伦's test: "The ASUS 4k30hdr capture signal shows obvious color banding compared with the passthrough signal" "It should have been extremely subtle even if it existed; you can't see banding in ASUS's passthrough either, but the capture signal is obvious" (on both a G6 and a miniled GX monitor)

• Hi: "ASUS hdr is 8bit, don't buy it" "avoid ASUS" "next time someone says ASUS is good, we say 8bit" "the only thing you can't trash is its price" (meaning the clearance price at the time)

• DRAKE: "ASUS has been confirmed to have color banding" "color banding plus no follow-up firmware support is a fatal flaw"

• The dirt the group dug up after "a week of research", which directly polarized its reputation [Other issues]

• PS5 handshake failure: yellow light flashing / HDMI dropout / passthrough frozen solid (requires lowering the transfer rate by 1 and resetting the passthrough signal source to default)

• "Stuck on the first step" "can't connect" "picture drops out" — multiple cases

• Discontinued and cleared out: no further firmware updates ("the biggest downside of the ASUS compared with the Kuhaomi G50 is that it's been discontinued, so there are no more firmware updates")

• YUY2 cut down (4K30 at most); no RGB output; stereo only (Dolby requires an audio extractor)

• Merchant / version confusion risk: "don't buy the wrong one, it has to be the 4kpro" (the regular 4K30 version is the HDMI2.0 one) [But why did it sell so well back then]: it's the "same solution as the G2", NV12 4K60 + 4K30HDR + 33-35ms bare capture, original price 2000, cleared out at 500-800. From 2026-09-18 to 22, "everyone had one" in the group, "this group has basically turned into an ASUS group", and Pinduoduo prices climbed from 499 all the way to 799 as people bought. [Current state, 2026-10-06] The clearance is over and the ASUS 4KPRO price has gone up — all of the above is history; stop looking at this card as "a steal / a value alternative", and when buying, compare it with cards still on sale such as the Kuhaomi G50. [Verdict] Second in total problems, but the problems are highly concentrated in "8bit HDR banding" (a hardware property, no fix) + handshake-type setup issues (which are solvable). Suitable for: people who would only consider it when the current price is clearly below the same-solution G50; users who mainly do SDR 4K60 and can accept HDR with banding.

3. Third place: UGREEN / HAGiBiS / low-price no-name cards — the highest "failure rate" bracket

[UGREEN]

• "This UGREEN capture card is absolute garbage" "died after only a few uses" (a CM701 user; the picture was abnormal in all three software apps, and only swapping the card fixed it)

• CM700: "washed-out picture, huge latency, returned it right away" "no matter which mode I set, the color looks a bit off, and the latency isn't much different from streaming"

• The 80-something-yuan model: "really bad, the latency is deadly"

• The UG701 (400-700 bracket) is relatively usable, but "the 4K passthrough version can only use the worst encoding format; with dlss5 there's very severe flickering"

• Coil whine cases [HAGiBiS] the 599-yuan model: two people's reviews after using it were "trash" "the colors are just a mess"; after switching to ASUS it was "much smoother" [Low-price no-name cards (100±)]

• "Cards at tens of yuan / a hundred-something / 200 yuan all have limited frame rates, blurry pictures, and obvious color shift compared with passthrough"

• "Capture cards should be at least 400 at full price; the 100-yuan ones are too much of a toy, the latency is sky-high, and they don't support vrr"

• Exception: the ms2130s reference design (80-150 yuan) is "usable" as a 1080P60 entry point (yuy2 latency 40-50ms) [Verdict] Most of these problems come from "buying cheap to try it out": the card is either returned or left sitting idle; better to just buy a model with a good reputation.

4. Hard spec flaws (not broken — just a bad buy)

[AVerMedia GC575] "It's supposed to be a flagship, and they cut 4k60hdr" "even the previous-gen 573 can capture 4k60hdr, and the new 575 goes backwards"; "4K HDR only p010 30hz"; "the 2.1 is useless"; "a trap at this price". Buying it is worse than a 573 / 4K Pro. [Kuhaomi 26P] "2K60 only", "4K just shows unsupported format" (several users sold theirs after testing); it's marketed as a "4K60 ultra-clear capture card" but nv12 only does 4K30 and RGB only 1080P; it suits users who only play in 2K. [AVerMedia GC553 old version / 553Pro] "553pro nv12 4k only 30 frames" "even 2k is only 50" "2K resolution not recognized" (an old-card EDID tier problem); "553 latency is still on the high side". [BLACKMAGIC] Professional film and video cards actually don't fit gaming scenarios: "PS5PRO 2160P60 only captures 4K at 36 frames in Veyra; OBS/POT are fine" — not recommended for gamers in the group.

---

5. Best reputation (for reference; the problem column is almost empty)

• AVerMedia GC553G2: the benchmark card, "lots of people in the group use it" (the author), and its issues are basically just individual setup problems

• Kuhaomi G50 / Michensen T800 / 27P: the author's main official channel picks, "same solution", transparent latency data

• Elgato 4K60 Pro MK2: the used "king of value", 32ms, 10bit; community members have tested it working on AMD platforms. Any PCIe detection issue should be assessed per motherboard/slot rather than treated as an AMD-wide incompatibility.

• Magewell 4K Pro: "out of this world" "ahead by a landslide" — but the latency figures are disputed (5-10ms vs 55ms measured) and the barrier to entry is high (20G C port, drivers, price)

---

6. Counting basis and limitations

7. This ranking is based on "the number and severity of problems that appeared in discussion"; each card's installed base differs across groups (the GC573 / ASUS 4KPRO have large installed bases, so their problems naturally surface more); the GC573 has the most problems, but it's also the "lowest barrier to 4K60HDR", and the player base drives the discussion volume.

8. The ASUS 4KPRO's "8bit banding" is a hardware property (no fix), while most GC573 problems can be solved through settings / repairs — the two are different in nature: the former is "that's how it is out of the box", the latter is "it's strong once tuned".

9. Low-price cards (UGREEN and the like) mostly have quality / failure problems, but because their user base is small, the total is lower than the GC573 / ASUS.

10. The group consensus in one sentence: "Three questions before buying a card: does the motherboard support it (USB10G / PCIe) → what platform is it (avoid MSI AMD) → do you want HDR (if you want HDR, don't buy an 8bit card)" ================================================================

---

7. This update: new cases after 10-06 (with dates)

The ASUS 4K PRO's HDR was disproven on the spot

• Remote_Sky (10-08): "The ASUS 4K Pro really can't do HDR, ugh, I bought the wrong thing before";
• After comparing P010 banding, the author (10-13) said flat out "ASUS is trash", and added "the T911 doesn't have it either (no banding)";
• Conclusion: 8bit is a hardware property, and no firmware can save it.

Elgato 4K Pro HDR turning red (fixable; this item wasn't in the original)

• 热心的猫舌头💡 (10-07): "4K Pro HDR turns red, and the 'open OBS once' trick doesn't fix it";
• The author admitted at the time "I tried to fix this thing with no success, for now use the OBS warm-up method" (the author 10-07);
• That same group member solved it himself the same day: "Upgrade Elgato Studio to 2.0 beta — it comes with a driver update for the capture card, and after updating it's fine";
• The author responded "how did you solve it? I'll write it into the docs" — already added to doc 01, section C2.

Elgato's RGB black screen (a new issue)

• YK (10-10): "Elgato currently has a problem where capturing RGB gives a black screen; all the weird problems are mostly on PCIe cards";
• Workaround: verify with NV12 / YUY2 first, don't jump straight to RGB24.

The 573's "luck of the draw" is confirmed again, but most cases are solvable

• YK (10-10): "The 573 has to go into a case PCIe slot; latency is lower and you gain 4K60 HDR, but compatibility issues are luck of the draw";
• 迅雷不及掩耳盗铃 (10-10): "I have a 573 too, and it had HDR red tint and oversaturation at first, then I followed an explanation in the group and solved it".

The cost of 4K30, quantified

• Shuuichi (10-08): "The 553G2 at 4K30 already has 60–80ms latency; after adding frame interpolation and DLSS5, is it still usable?";
• The author: "Capture 4K60 and the latency can be half that" (the author 10-08);
• kabuto (10-23): 4K30 P010 "feels completely disconnected from your input".

The 27P's real specs

• The author (10-10): "The 27P can't capture HDR, only passthrough has HDR, but we don't need it" — don't expect to record HDR before you buy.

8K upscaling blows up VRAM

• 月光疾风 (10-12): "Clicked 8K once and it blew up"; owen (10-12): "I tried it too, blew up the same way" — not a one-off.

New card reputation (for comparison)

• T911: "works great" "barely different from a direct monitor connection" (富樫勇太 10-21), "can't feel the latency" (玛卡巴卡 10-26), "I really can't feel the latency anymore" (a group member 11-02).

Chapter 04 supplement: new failure and blow-up cases (10-06 to 11-05)

Filtered from the records of 7 community groups, 2026-10-06 to 11-05; 1723 relevant messages in total.

Key points this round

• ASUS 4K PRO HDR disproven: "The ASUS 4K Pro really can't do HDR" (Remote_Sky 10-08); the author 10-13: "ASUS is trash" "the T911 doesn't have it either (no banding)".
• Elgato 4K Pro red tint is fixable: "Upgrade Elgato Studio to 2.0 beta, it comes with a driver update, and it's fine after updating" (热心的猫舌头💡 10-07); the author's own words: "tried to fix it with no success, use the OBS warm-up method for now".
• Elgato RGB black screen (new): "capturing RGB gives a black screen; all the weird problems are mostly on PCIe cards" (YK 10-10) — switch to NV12 to verify first.
• 573 is luck of the draw but mostly solvable: "mine had HDR red tint and oversaturation at first, later a note in the group solved it" (迅雷不及掩耳盗铃 10-10).
• The cost of 4K30: the 553G2 at 4K30 is 60-80ms to begin with (Shuuichi 10-08); kabuto 10-23: "4K30 P010 feels completely disconnected".
• The 27P has no HDR capture, only passthrough has it (the author 10-10).
• 8K upscaling blows up VRAM (月光疾风 10-12, owen 10-12).

Group members' own words (with dates)

"@Likely7 xsx streaming with frame interpolation freezing the picture hasn't happened yet; everything is normal so far except the NR black screen"

— Snicer 9070xt (10-06)

"AVerMedia can capture 5.1, the latency is most likely the same, and both support 4k30hdr"

— Focus (10-06)

"pcie's advantage is that the board can be bigger and cooling pressure is lower, bandwidth is higher, and if it's a CPU-direct pcie lane the transmission latency can be lower"

— Snicer 9070xt (10-06)

"[Video Channel] Elgato 4K Pro PCIe internal video capture card 8K4K HDR passthrough low-latency game streaming recording card PS5XboxSwitch universal"

— Illidan (10-06)

"Recording and passthrough are two different things; the latter even a garbage card can push very high"

— Focus (10-06)

"Though there seems to be Magewell above that — I saw a test before where the latency was quite low, but it didn't look like a recording test under 4k30hdr. With this stuff you can only try it yourself; there are far too few online side-by-side comparisons to go on.."

— Focus (10-06)

"Is the 553g2's 2k60hdr also 10-something latency?"

— Milk (10-06)

"But renodx also depends on the author's skill level, it blows up sometimes too"

— Focus (10-06)
