Answers to questions & suggestions:

1. Do any videos play on the LG TV.

Yes. >MOST< of my 4K videos will play on the LG OLED-77C1AUB.AUS through an external SSD connected via USB. >ALL< of the fast-forward sequences fail at some point in the sequence. >SOME< of the normal-speed 4K video also fails during the normal course of playback (which, to me, suggests the TV processor is unable to process the bits coming in).

It doesn’t make any difference if the source device (into the USB port) is a thumb drive or and external SSD.

Also, I have tried different USB ports in the TV. No difference in performance.

2. Do the videos play on your PC?

Everything plays just fine on my Windows 10 PC—irrespective of whether the file is on an internal SSD or external SSD via USB. No problems. Smooth as butter.

(I do not have another TV to test on.)

3. Version of Resolve?

Paid Studio version.

4. Bit depth?

Bit depth = 10

5. Have you tried MOV?

Yes. The MOV file crashes much worse than the MP4 files.

I have tested several additional variations since my original post. (Everything below was rendered H.264 codec, 3840 x 2160 UHD—except the one Hi Res file as noted. All 29.97 frame rate.) Render speed in DaVinci = 10%.

“Failed” means that the video and audio failed to play back smoothly. It stammered, stuttered, paused, and generally “choked” (my terminology for all of the above).

1) MOV played back via thumb drive = fail.

2) MOV PB via external SSD = fail.

3) MP4 rendered “high” vs. “best” PB via thumb drive = fail.

4) MP4 rendered “high” vs. “best” PB via external SSD = fail.5) MP4 rendered Hi Res 1920 x 1080 = still failed!

5) MP4 restricted to 8,000 Kb/s = played back but severe pixelation (defeats purpose of 4K).

6) MP4 restricted to 10,000 Kb/s = played back but severe pixelation (defeats purpose of 4K).

I also attached the external SSD USB drive to my Surface Pro, and played the same video file on the SP via HDMI to the LG TV. The 42-second test clip appeared to play fine this way on the LG. Hmmm. Again points to the TV processor.

However, I don’t understand why it would choke on the fast-forward rendered segments. Rendered video is rendered video. Would there be more data in the fast-forwarded segments? I’m not an engineer, so I don’t know the answer to this question. The fast-forwarded segments are where the video ALWAYS fails.

Tom: If you (or anyone) wants to roll up your sleeves to test this, I can provide a link to download my ~ 42-second 4K test clip. You can test it on your PC, and then test it on your LG via a USB connection.

(Creative Cow will not allow me to add the link here.)

LG, working through a local repair business, is scheduled to send a new main board next week. I have a hard time believing that a new solid state board that passed LG’s QA went bad. However, the TV’s on-board processor does not appear to be up to the task. If that’s the case, the TV’s performance isn’t meeting it’s own specifications, which are available here:

Thanks to everyone applying brain cycles to this. I appreciate your help.

Jon: Thank you for your suggestion. I will test quality settings and report back.

Tom: Thank you for your suggestions. I will test these scenarios and report back.

Hi Steve, and thanks for your response. I have noted these decks, and will look around eBay. Capturing form the Sony DCR-TRV320 camcorder works reasonably well. My oldest tapes date back to 1985, and although there are a few dropouts here and there, the quality is surprisingly good.

Cheers,
Karl

One last post related to this thread: I discovered that Vegas 16 Pro will capture the video, but only to the C-drive.

My C-drive is dedicated to the operating system. So this required quite a bit of experimentation to discover what the issue was.

Cheers,
Karl

John & Francois — Thank you for your continued support here.

I had tried Scenalyzer previously, but I had not had a key to the SW. Now with the SW key, based on a quick test of about 1-minute of video, Scenalyzer appears to work.

LOL! One fellow in his garage (or attic) codes software, now eight years ago, that can capture video where Magix (Vegas) and CyberLink (PowerDirector) can’t. As a former software guy, it makes me laugh.

So far, so good. I will see how far I can get with Scenalyzer, and report back.

On a tangent, I suspect that my Sony DV camera is perhaps too outdated for the contemporary software above. Are either of you aware of any replacement hardware for playing back these Video8 and Hi8 tapes, that is compatible with Vegas 16 or PowerDirector, and also doesn’t cost $500?

Thanks again. I knew Creative Cow would come through. Moo!

Francois — Thank you for your response and for attaching the application.

The application appears to be a video import utility (vs. a video tape capture utility). It is designed to import video files from data drives. (See attached screen shot.) It does not recognize the camera via FireWire for live video capture. I need to capture DV tape from the camcorder via FireWire.

Either I am misunderstanding the application (possible; but I don’t think so)—or perhaps you uploaded the wrong app?

Thanks again.
