iuVCR currently free?

[aramkolt]

Not sure how popular iuVCR since there are a lot of other programs that can do similar things (virtualdub, ATI MMC), but I did see there is a guide here on how to do the initial setup.

While downloading it from the developer's website to try, I noticed that they have a free registration key posted, apparently because payment processors aren't working with him anymore per google translate.

See here for key if interested:

Played around with it a bit, and the interface seems nice, shows dropped frames, current file size with MB/min and CPU use all in one place. I saw the notes here look like it can have sync issues, but not sure if that is something that was fixed after the guide was put up as it does seem to be a newer version as the menus do not exactly match from the screenshots.

If you end up liking the software and use it in your workflow, would be nice to kick a donation their way. Probably can figure out how to do that if you use the "contact us" link at their site if they respond to a message about it.

Would also like to hear from anyone that has strong opinons on why they do or don't use iuVCR from those who have used it more extensively.

I tried it on Windows 11 but it was installed in a language that I don't understand, Probably Russian but my system can't display Russian so it's all gibberish, so removed it immediately.

Edit: I installed the beta version and it's in English, I will give a try later with actual hardware.

I tried it with a video source and it works just like MediaExpress, very light weight, detects the source format automatically no initial setup needed, However audio gives me only two options 16bit or 32 bit float, MediaExpress capture in 24bit by default.

What capture card are you using there and is that sample at SP speed, SVHS, or perhaps a digital source output as analog? Just looks extra crispy and relatively noise-free compared to what I've been working with haha.

There are two pieces of software and not sure how different they are from each other performance-wise - The newer one is iuVCS, but the older one is iuVCR. They note that iuVCS has a reworked capture engine, though I don't know if iuVCR is worse in any way.

I did notice some audio sync issues in my very short testing of iuVCR, but I haven't tried it with a time base corrector yet to see if that makes a difference to audio sync. Mine was just straight out of a HR-VS30u with line TBC on a tape recorded in EP mode/non-hifi

English version of all their apps should be here:

I used iuVCR some in the early 2000s (with non-AIW cards), and it was a favorite of several VH members and mods at the time. VirtualDub was somewhat lousy back then.

I still have the English downloads from the 2000s.

Within the past year, I tried to download the "new" final 2011 version, and also ran into the Russian issue.
latreche, did you resolve that?
I also just uninstalled it, not wanting to spend much time on it.

I see, I installed this and now I have both iuVCR and iuVCS in English, Don't know what the differences are but will have to do more testing and seek the possibility to add HuffYUV since it has an option to add codecs but not sure yet how it works.

The material shown is analog Betacam SP by the way.

[aramkolt]

It seemed to auto-populate all of the same codecs that virtualdub and MMC could see right away without any fancy configuration or installs on my XP machine, so the testing I did was Huffyuv. I did notice that the actual capture statistics that app shows (very handy) was showing an average frame rate of 29.965 or something like that, so could be that my VCR outputting frames slightly slowly and hence the audio drifts if the video later gets played back at 29.97 exactly. Guessing the audio stays the same length and the video gets a bit shorter by the end.

Fix I think would be a timebase corrector which I'm thinking *should* insert the occasional frame to get it to exactly 29.97 frames. I know before I was asking how to tell if a TBC was actually working correctly - I take it one way is to see such frame rate statistics be solid at at 29.97 without drifting?

[latreche34]

I don't think the average frame rate display has anything to do with TBC or VCR, I don't know why it shouldn't display a fixed fps. Anyway the license key doesn't seem to work for me, it keeps asking for license on every startup.

I have HuffYUV installed but I don't see it in the codec list.

Figured out the registration problem, I wasn't putting Free_key as a name.

I vaguely remember iuVCR not locking 29.97 static, now that you mention it.
