How to get perfect 60i-to-30p deinterlacing + 60i-to-60p-like Slow-Mo...
 

This works with any 60i footage, and works quite well... I'm surprised more people don't know about this.

Project settings
Field Order - Progressive
Deinterlace Method - Interpolate Fields

That gets you 30p out of 60i, Vegas does it in real-time, you may have to change your preview window to Preview (Half) or Good (Full) to see the results... I leave mine at Good (Full) 24/7

Then for rendering, just make sure you choose progressive for field-order if there's an option.

And finally for the slow motion, after you've done the de-interlacing method above, you simply right-click on the clip you want to be slow-motion and change the playback rate from 1.000 to 0.500 ...

It's incredibly simple and produces great results. All of this was shot with an FX7 at 1/1000 shutter... The FX7 can only shoot 1080i60, and all of this was edited in Vegas 8.0/8.1 and captured with HDVSplit

I've tried this with my old footage from a Canon Elura 2MC 480i60 camera... and it worked just the same...

Joe, why do you use Interpolate Fields, instead of blend and how does it work better?

Blend just blends the fields together... Interpolate creates progressive frames out of interlaced fields. It rather cuts out every 2nd field and fills in the missing information.

Regardless, Interpolate fields produces what true 30p should look like... watch the videos... pause it on a frame and it looks progressive with no signs of interlacing ever being there.

Try Vimeo!
 

Nice job; thanks, Joe.

But I wish more people would use vimeo.com for posting their video. Not only is the quality much higher, but you can let people download your source clip, giving them a much clearer picture of what was created.

But once again, thanks for the post!

The quality is in fact not higher on Vimeo. And frankly, not everyone WANTS people downloading their stuff. Vimeo also doesnt support 30p, which many, many shooters use.

Oh, sorry. I was just frustrated that the YouTube HD version of your clip was playing back at maybe 5 frames per second on my mac tower. Ended up watching it in low (standard) quality. Fun footage, though.

You mentioned in your post getting 60P - what settings do you use to get that?

Also, if you decide to give Vimeo a try, the download option is just an option. You can set your video to not download, or even to private. I use the private option for transferring very large video files to clients; it's very useful.

For transfering large files to clients try mailbigfile.com.

I use it, it's brilliant and easy.

I do the same when shooting 60i, and edit progressive in vegas, however, i use cineform to deinterlace, in my opinion it deinterlaces better, this is link to an example of how to deinterlace, I have tried it, it creates huge files, but its something think about

What is deinterlacing? The best method to deinterlace movies

Nice; thanks, Hugh.

Paul, yes, mailbigfile is good, but I like that on Vimeo they can simply preview the clip for content and edit without downloading, and if it passes muster, then they can choose to download. It saves steps, and time, and time, after all, especially these days, is money.

Heh well here's some full 1080p .wmv's

I've tried that method on 100fps and it's a ton of work, when Vegas does the same thing for zero effort.

Honestly give it a shot, change a few settings around and render some of your video out, I think you'll see the results are identical.

I actually looked frame-by-frame and the "fake" 60p slow motion looked sharper/had more detail than the regular de-interlaced 30p.

I think the advantage of keeping the source files in 60i is that Vegas can now "create" the missing frames for slow motion out of those 2nd fields that would be lost if you gave Vegas 30p as source footage.

There is some good information on that site but I think some is not correct. I do not think cameras MIX fields together which is stated on that site. In fact several modern cameras capture full frames and then output what has be prescribed. A true interlace camera send/records fields every 1/60 sec they are in essense half of vertical resolution of a 60fps capture, first odd then even field every 1/60 sec. I have always had this problem with understanding how this is 30 frames per second!!! To me it is only 30 because 60 divided by 2 is 30. Simplistically adding these fields results in the poor deinterlacing often seen on PC screens as they are captured 1/60 apart as is clearly demonstrated with pictures on the site. A better way would be to use several sequential fields to interpolate a full 60fps progressive output( recreate the missing fields for each frame) as several high end external hardware boxes do. I am not sure if Vegas does this but that would be great as I am not a fan of low frame rates. I like the smooth motion that interlace gave on a CRT.

what are your render settings to get such good quality on youtube?

Just upload it at 1280 x 720, Youtube has an "HD" feature now..

It takes a couple hours to show up after uploading.

The link I gave you had &fmt=22 at the end, which forces HD mode, if you give someone a normal link, they'll have to click a button under the video that says "Watch in HD"

however the debate ends, that is absolutely killer camera work....nice. I love the FX7, such a great cam. We use it from a helo constantly. Why the 1/1000? Better for quick action?

1/1000 "freezes" the motion better in each frame... I think it looks better than having a bunch of motion blur atleast for action.

And that's all with a cheap friction-head tripod... was like $400 from Bogen/Manfrotto...

Looking to grab a Vinten vision 3 here pretty soon... which should make for smoother shots... :D

As much as it pains me to say it, that is very nice footage Joe :) I think the slo mo at the beginning of one clip is slowed down a bit too much, but that is a minor quibble.

Yea that's 25% slow motion... it looked bad, but the flickering effect sorta went with the music so I left it in. All 3 of these clips were edited within 45-60 minutes usually...

I changed it in further "revisions" but who knows what will happen...

I must say that I am still stunned. That footage was awesome. The level of detail was intense. This is probably a stupid question but I have seen references to "HDVSplit" on several occasions. What is it? Is it a stand alone or plugin, i have always been capturing my footage with vegas's internal capture. Something tells me that i have been making a mistake...

There's no difference in the quality between the two captures, it's all digital..

HDV Split just makes it simpler, allows a full 1920 x 1080 preview (although it is interlaced so it doesn't look too great) but allows for labelling of files using the time-code and automatic scene detection

I like it.

Kev,

I liked your footage and went straight to my vegas. I followed directions to the part about changing from 1 to .5.

At this point I right click on the clip and can not find that at all.

I am in 8.0c

Right click and hit Properties... then do you see playback rate?

The playback rate can be changed multiple ways. To me, the easiest way is to hold down the CTRL key and then resize the event long (to slow it down).

You can also right-click it, and choose Properties. That will show you the Playback Rate setting along with many other settings.

With the pro version, you can also change the playback rate via a script.

Joe,

I got that sorted out, did not see the properties at the bottom and went to file, I must be impaired in some way!!

This method works well, Then apply a velocity envelope and you can bring it back a little more.

I now feel I can shoot the falcons at a higher shutter speed and not get stuttering or flicker. I will post a shot, however it was shot at 1/60th of a second.

I will post a stoop of a falcon as soon as I get it down loaded to vimeo

Yea, but holding down ctrl does not make it exact.

It needs to be exactly .500 or 50% slow-motion for this to work right.

Even setting higher like 75% slow motion you get ghosts/doesn't look right, but at 50% it looks perfect.

If I have to have an exact speed, I'll use scripts. With my script, I can set it to an exact number AND it will auto resize for me so that it matches the new speed.

With the proper settings turned on, the speed percentage WILL display in the audio (assuming what you're changing the speed of HAS audio) so you can be fairly precise using the CTRL-resize as well.

Where can we get this script ?

Thanks.
Paul.

I use Excalibur for this. I wrote Excalibur. I wouldn't be surprised if other scripts somewhere will do the same.

Hi Ed.
I just downloaded and installed excalibur, how do i use it within vegas ?
I can't see anything different in vegas.

Thanks.
Paul.

Found it.
View>extensions

Paul.

Yes, it's a custom command in Vegas Pro 8. As such, it's listed under extensions (there are three in Vegas Pro 8 - Tools, View, and Edit) unlike previous versions where it was listed under Tools - Scripting.

Once open, you can leave it open all the time in the docked area. When you exit and restart Vegas, it will automatically restart as well unless you manually exit out of it. It's totally free to use and fully unlocked for the first 15 days.

Hmm, is there any loss of detail by using this deinterlacing method? Because i'm pretty sure that there has to be SOME loss because it's filling in some data that isn't there...

Excaliber ?
 

Edward,


I checked out Excalibur and Liked it!!

I downloaded it and it is all in a folder in my documents, How do I get into vegas pro 8c?

do I need to go back and download again to a different location?


thanks

There isn't really a loss of data.

I actually found my 50% slow motion is sharper/more detailed then the plain de-interlaced footage which is interesting.

Native 60p footage is definitely better, but this is a really good alternative because a.) You would only be shooting 60p if it was to get better slow motion, final render will still be 30p. b.) There aren't really any consumer/prosumer cameras that shoot 1080p60 anyways

Actually...Sanyo just announced some consumer cams that will do full 1080/60p. Although obviously it's not directed at people like us.

Digital camera | TOP : VPC-FH1 | SANYO
Digital camera | TOP : VPC-HD2000 | SANYO

Yea I know that one... there are a lot of cameras that do 720p that looks about as good as 480p "blown-up" to 720p...

I could say my FX7 shot 2k if I just up-rezzed it a bit right? -_-

Sanyo say the sensor is 1920x1080. Do you know something we don't Joe?

Richard

HV10 had a 1920 x 1080 sensor too...

What's your point?

Dale, the download is an installer. After downloading, run that program and Excalibur will install. After installing, in Vegas Pro 8 go to View - Extensions and you will find it there.

Sorry, maybe I just don't get your point Joe. Are you saying the image from these cams is like 480 lines uprezzed to 1080? I haven't been able to find any sample footage from the HD2000 so far. What is this opinion based on?

Richard

I'm saying that the pixel density of the sensor doesn't really matter. You get crappy footage out of crappy cameras.
