Video rendering help
 

Hi,

I need some help with rendering videos. I don't know how to describe it, but it looks like lines throughout the motion. If you check the clip, look at his hands while he's stroking.

video test

What causes that? And more importantly how do I fix it?

Anyone know what we aren't doing right?

Jimmy

You need to deinterlace it. What program are you using to edit/encode?

Yeah, we tried deinterlace options, but the options in Vegas don't seem to do anything.

We have Sony Vegas 9, Sorenson Squeeze 5, Virtualdub, and Avisynth.

Clips start as .mts files in Sony. We edit and rendered to uncompressed avi. Then use Squeeze to make flash file.

Jimmy

If you are using Mini DV or HDV 1080i export, thats your problem. You need to either output as 30fps or 24fps to avoid interlacing.

I've had issues in the past where you mark the option to deinterlace in squeeze and it doesn't really do it. Re-encode direct from your editor to mpeg2 with deinterlace set.

Its AVCHD content. And yes, we are rendering with 29.97fps.

Jimmy

You can de-interlace at almost any point in the process, but I prefer to do so upon capture or when I export an intermediate AVI file.

In otherwords don't trust sorenson to deinterlace. You should have a perfect looking product direct from your editor in the largest format you can. But it should be a ready to view product even if its not a format to give your members. Then you can batch that in sorenson to all the formats you need.

Bingo. How you doin Jim? Been awhile since we talked. You have any shows you are going to in the near future? Vegas?

Yes, I'm using Vegas to attempt to deinterlace it, but it doesn't seem to work.

I'm going to try again rendering to an mpeg2 this time instead of avi.

Jimmy

Ugh. Still no fuckin luck. Does the same damn thing.

Jimmy

You should try for dat.
:thumbsup

Hello..

If you want to resize an interlaced movie in any program, it will be deinterlaced automatically. I have a cam that makes .MTS files (50i or 25p) and had problems converting them into some usable format.

Then I found a nice free tool called "MTS 2 XVid" , its very small, fast and easy, you just put all MTS files into its directory and it converts them into XVid with just one click. You can set all parameters (resolution, bitrate..). I resize them from Full HD resolution to 1280x720 and the files are deinterlaced automatically. Then I edit them easily in Adobe Premiere Elements.. Let me know if you cant find this proggy via Google.

Good lead. I found it. Now to just get the correct settings and try it through Vegas and Squeeze. The author does say it is an outdated process though as of last month. But if it works, I don't care.

Jimmy

Good.. you have to edit the file with your settings to set resolution/bitrate etc. There is a .txt file with url to the documentation, shitload of settings to choose. The program is very fast compared to others. Editing Xvid files is very easy after that, as long as you have the proper codecs installed (ffdshow)

Do you have the url? I don't have a txt file with that.

Jimmy

Not every program deinterlaces automatically. And he will have issues if he encodes first into xvid then wants to go into another format.

Any NLE should be able to deinterlace without a third party program.

The bat files have a deinterlace option, so thats what he meant.

It is encoding to a .avc file actually. And it appears after editing in Vegas, it looks much better. We shall see in a few minutes if I don't fall asleep.

Vegas' deinterlace options are not working.

Jimmy

Stop using shitty programs! Use FCP or ADOBE Premiere Pro. Problem will be solved.

Well the second half is true ;) hehe. Premiere since 2000 here lol

VirtualDub deinterlace MUST work!

I use Premiere Pro CS4 never had those interlaced jagged lines.

Proc: i-7 core 950
RAM: 12gigs
GPU: ATI 4890
Dual 24" Monitors
HD: 320Gig 1500RPM primary drive.
HD: 4- 1 terab drives for storage.

No I am not bragging about my HD video editing machine. It is just a tool to get the job done quickly.
However, this is the fastes machine I have ever seen. It cuts through full 45mbs HD video like butter!

I am going to take a guess at the problem that is occurring on your video.
I am guessing you had the capture set at 50hrtz and not 60hrtz and when you import into your software probably at 60Hrtz you are getting visible interlaced lines.

I would recommend "smart deinterlace (2.8 beta)" from Donald Graft. Much better the the deinterlace filters virtual dub has on board. Search for it in a search engine, download the zip file and unpack it in the plugins folder then add it in the vd filter menu.
I have used this filter in the past for rendering before I developed my own avi-synth scipts wich are secret like the coca-cola mixture :)

Adobre Premiere Elements wont open my .MTS files.. why the hell would I use another program at first if I could do that all in one?

1. You CANT resize interlaced movie without deinterlacion, so no.. each program will either deinterlace automatically or it simply wont do the job.

2. I have no issues editing XVid files in AP Elements and export them in .WMV (WMV8 or 9) with high bitrates and quality.

No, I didnt use any deincerlate settings, it just does that automatically if you resize the movie ..as it cant be resized without deincerlation.

The program encodes in .AVI (xvid codec) , not .avc

ffmpeg - http://ffmpeg.org/documentation.html

I hope you have the correct proggy :) Edit the "_multi_demux_mts_xvid.bat" file, there are the basic settings at the bottom already set

He is not capturing anything, his cam makes playable .MTS files, not RAW footage.

Nope.

Jimmy

My system is better than yours! :P

I'm not capturing. The camera makes .mts files for use str8 in video editor.

Jimmy

Hmm, the xvid.avi files outputted were crap. Although I didn't mess with the settings much. I thought the .avc file was what I was looking for because it looked really good in Vegas.

Try some more....

Jimmy

Do you shoot at 50i or 60i?

Have you try it with the standard settings at first?? If so and your Xvid files looked crappy you probably need to update codecs, try K-Lite codec pack.

Must work for you, I got nice deincerlated files after using the proggy.

Its 1920x1080 60i

Jimmy

Try the K-Lite codec pack + check out the settings, it must work

I tried that in VirtualDub, but didn't get good results either. Plus I only know how to save as avi, then use in Sorenson. Long process and no good.

Still trying to tweak ffmpeg right.

Jimmy

This shit sucks. Now the videos are blocky.

Jimmy

eh? Where did you get that? On you can't resize without deinterlation? lol

Dude hit me up on icq, I don't like givin away a lot of free info on the forums since I do video work for people still lol.

You cant.. the picture gets fucked if resized before deinterlation.. any software I have used deinterlaced the video before resizing it. If you resize interlaced video and the output stays interlaced then I am sure the software deinterlaces it first then interlaces it back, although I have never seen that. Keep dreaming.. :1orglaugh

this is what I use with MTS_to_AVI

-threads auto -vcodec xvid -s hd720 -maxrate 12800k -b 12000k -qmin 3 -qmax 5 -bufsize 4096 -acodec mp3 -ar 48000 -ab 160k -ac 2 -y "%%~na_xvid.avi"

Gives me HQ playable and DEinterlaced files

Think you be confused.

No I am not, I speak of my own experice.

mr dreams.

i use vegas 7 & had the exact same issue. give this a try, it worked for me.

when your video is on the timeline, right click on the video & go to properties. you should see a checkbox to "reduce interlace flicker" check on that & re-render. it worked magic for me.

not totally sure your vegas, which is more updated than mine, still has this, but i think it should. GL.

That didn't work. It appears you have an older ffmpeg than I do, but after I got it working, it makes a really blocky video.

I'm giving up on anything VirtualDub or Avisynth. The link above also, gave very bad colored blockey video.

I was able to get some better looking avi's through Vegas. But they still have some lines in them. They are no longer comb lines or blocks. Just a single line here and there throughout the motion.

How can you tell if your avi is perfect before you put it in Squeeze to convert to f4v?

Jimmy

Play it in WMP or VLC Media Player.

Its too big, makes it choppy. That 3 minute clip is 33gb avi.

Jimmy

Here's the latest version. Looking better. But not there yet.

video test #2

I think it will look even better when we go to 1280x720, but want to fix everything before we resize.

Jimmy

dump for a good thread. Love the video talk

So how does the 2nd version look? 2 posts up.
