That is true John, good thing I had some experience with Avisynth and Virtualdub. I’ve heard that there was a wrapper plugin for Vegas (debugmode’s frameserver) that could incorporate AVIsynth filters for use in vegas projects, hope it supports 64-bit.

After Effects’ time stretch was a cycle of trial and error – on some of the footage, I would get the desired effect, on others there would the weaving effect (where two fields are shown in one frame), “field bob” in Virtualdub deinterlaces well with interline twitter and “bobbing” that is very reminiscent of the analog days when such video was slowed down.
Speaking of analog, would you happen to know what interlaced analog formats there were for professional use using a composite signal (e.g. video production, television and broadcasting)? Sony’s Betacam and Panasonic MII are analog but record component video, I’ve seen some Canon video production equipment and wondering if they had their own format.

If Vegas will have more deinterlacing methods in future, that would be quite handy for me.

Edit: This is a question that I’m asking others as well, but what are your thoughts on interlaced material with regards to its limitations and/or difficulties (e.g. deinterlacing, resolution, artifacts)? Thanks.

I’ve tried it following the author’s website instructions, but on smart resample, ghosting is still there but with reduced visibility when slowed down to half the original speed compared to interpolation by vegas and on disable resample, the footage becomes 25p at original speed so the extra 25 deinterlaced frames are gone.

Yadif Deinterlace for Vegas doesn’t do double-deinterlacing like Yadif(2x); (if it can I believe that disable resample shouldn’t affect it). This was mentioned on author’s website saying that it doesn’t double the framerate because the port only features modes 0 and 2 present in the old Yadif (https://forums.creativecow.net/thread/24/923607), modes 1 and 3 doubles framerate.

Now I realise that I need a plugin that could do “Bob” deinterlacing which would do double-deinterlacing.

Hi Steve,
I understand what you’re trying to say and that’s what I have already tried, both with resampling set on smart and disabled on the video events, but they didn’t give me the effect that I desired. I think I would have to render the 50i source footage to 50p using interpolation and then disable resample on the interpolated version, then I could slow down and get duplicate frames without ghosting, but the original interlacing artifacts would have been lost.

Why I’m doing this is because I’m interested in the limitations of interlaced editing systems of the 1990s, when interlaced video was the standard. Whenever a scene needed to be slowed down, it would introduce interline twitter and other interlacing artifacts, mastering it again in interlaced format would cause this to be even more visible, which is what I’m aiming for my project. People tell me that

So far, time stretching the footage in After Effects achieves what I want, but I do need a bit more experimentation. I appreciate and thank you for helping out with my problem.

Thanks for your help John, I’ve encountered a problem that I could solve myself, but was wondering if Vegas has a deinterlacing method without resampling, which would make my workflow more efficient.

Basically, I’m trying to deinterlace (interpolate) DV@50i into 50p for a 50p project and slowing down the deinterlaced footage to half its original speed, only thing is that smart resample would frame-blend neighbouring frames and cause ghosting which is not what I want, I want the “duplicate frame” effect which is achieved with disable resample but it loses the extra frames from deinterlacing.

Any ideas? Otherwise I’ll have to time stretch the source footage in After Effects with some sort of envelope like the velocity envelope in vegas pro.

ok, thanks for the help and advice john, for the sake of vegas it’s probably best to keep it separate from transcoding.

I don’t update vegas often, so I have lack of knowledge on which builds are stable and which are not, think I’ll try Vegas 12 after doing a fresh OS install, would you happen to know from your experience which builds of Vegas 10, 11 and 12 on x64 are most stable or comparably less bugs? (i’m looking for builds where vfx1.ofx and compoundplug.dll behave well)

Something off-topic, but do you have CPU parking disabled? What are your thoughts on this and would you recommend this? Thanks.

Apologies, was supposed to have a link in the previous post of how the glitched preview looks like (it’s not from my scenario with the AVC MP4s but it’s visually similar in appearance): https://i110.photobucket.com/albums/n119/lqcorsa/24234_zps951e47c8.jpg

Forgot to mention I disabled most of Microsoft’s codecs using “Win7DSFilterTweaker” so that “multiavchd” can actually work. Would vegas have problems if the default microsoft codecs (wmv/mpeg/h264,etc) are disabled?
I do see glitchy thumbnails in Windows Explorer for a couple of SD AVC encoded MP4s but when I revert back to Microsoft’s codecs, they show up fine.

Technically, would repairing(reinstall without uninstall at first) a vegas installation replace its set of codecs with fresh copies or would that require a total uninstall of everything codec related?

Do you happen to have problems with “vfx1.ofx”? In my build(583), video effects from “vfx1.ofx” like “(sony) color curves” tend to have blank video event FX windows (just the pan/crop, preset select and nothing else) which requires restart of vegas because it would crash if I continue doing anything at all, even clicking anywhere. The FX window does function as normal after restart.

I have read on the forums that “vfx1.ofx” might be buggy. I tend to use “color curves” and “color corrector (secondary) a lot and they’re usually coupled with other 3rd party effects I have like twixtor 5.1.1.
My views – either I’m past the limit of instances of “vfx1.ofx” I can use or it’s just not happy with certain 3rd party plugins.

I’ll have a look at cineform then, thanks for that.

Wasn’t able to get a screenshot of the glitchy preview but it was along the lines of this:

I do know that installing codec packs is bad for Vegas, but would manual installations of ffdshow and haali affect vegas? using “multiavchd” to transcode(convert) some videos which requires a proper playback chain setup.

[Rick Anvican]

I’m trying to convert videos in delivery format to editing format – which codec(s) do you suggest would retain original quality? Size is also an issue but it just means I have to get more storage.

After seeing your reply, I think the glitching is caused by the mix of the source videos I used in the projects, with supported codecs including those in delivery format, think it’s probably best to have all source video using a single codec.

I think my installation of Vegas Pro somehow has the error reporting disabled so it always gives me exception messages when it crashes, some I can ignore (e.g. compoundplug.dll), others would quit to desktop (e.g. vegas110k.exe). The glitch-ups that happen after a period of time for me would occasionally occur after an exception message related to “vfx1.ofx”(Vegas’ color correction/color curves and other sony video fx).

Thanks for replying John, a few MP4 files I have that are not working well with Vegas are actually from Youtube (videos uploaded around 2011) prior to their switchover to variable framerate AVC, I’m looking into using Telestream’s Episode to transcode then for the more problematic ones. Remuxing to M2TS works for majority of them most of the time, though it has the occasional glitch so I would restart Vegas before I render(export) anything.

I know them DLL files will cause damage but I only change folder names like add “_” to the “compoundplug” folder to disable it and then revert it back to normal. Variable Framerate (Youtube) AVC was able to be decoded properly by quicktime. Is there a way in Vegas where I might be able to set a certain codec to use quicktime to decode instead?

I’ll see if I can replicate the garbled preview with such MP4s and give you screens of file properties readout in Vegas. Relatively new to the forums – FILE UPLOAD is the one for the dropbox? Thanks again.

(Do you guys get rare glitch-ups with the preview/render garbled after like a period of time using Vegas, for me about two hours on any project using videos of any supported codec?)
