Capturing from YouTube

[suppafreak]

Hello,

I captured a HD clip from You Tube. The clip was saved as mp4 file. When I play the clip in the Windows Player the clip plays fine with out any distortions. When I play the same clip in Premiere there are a lot of pixelation. during motion.

Here is the screen grab from Windows Player


However when I play the clip in Adobe Premiere there are a lot of distortions during movement. I assume some how Premiere's mp4 codec does not interprets the clip correctly.

Here is the same screen grab from Premiere.


I search the forum for the best capturing software for capturing from you tube, but could not find anything useful. I found something called "Supper", but I could not install it. I used Best Video Firefox extension.

Is there a way to fix it?

Thanks.

This thread would be more proper in our Video Streaming Forum. Moving you.

Try rewrap it to avi with mp4cam2avi. Or reconvert to a lossless avi with avidemux, open mp4, under video choose for huffyuv, save as avi. Then open in premiere.

Thanks will try.

Playing *.mp4 and *.mts/mt2s (AVCHD) clips after dragging them to the timeline has always been like this in Premiere Pro CS5 (at least as per my experience; suppafreak is the first here to corroborate that). This is even if the mercury engine is h/w enabled, etc; amazing, when the same clips DO play smoothly in WMP. I've always wondered why, but it has seldom bothered me because I always convert to Cineform (bonafide VfW) before any editing is performed.

Both of those did not work. I tried avidemux as you suggested but premiere could not ope the file. I tried bunch of other setting combinations which did not work. MP4Cam2Avi also did not work. In all cases the converted file would play in windows media player, but not in Premiere.

so what would you suggest?

[poisondeathray]

His suggestion was to re-encode it with cineform

If you are using cs5, the other suggestions might not work , unless you have 64-bit version of the decoders installed e.g. huffyuv 64-bit , previous versions of premiere were 32-bit and should work with 32-bit VFW decoders

[poisondeathray]

out of curiosity, can you post the youtube url to the clip ?

turk690 claims to have seen this with AVCHD clips , but I never have. My guess is that premiere's problems with this youtube clip problems are from either weightp, or open GOP or non IDR keyframes . AVCHD has none of those, and have fixed GOP, very standard stuff.

If you know how to use avisynth, another option is to use avisynth virtual file system (AVFS)

Where would I get the 64bit version. It looks like the website has only 32 bit version?

You can try 64-bit huffyuv here
http://members.optusnet.com.au/squid_80/huffyuv64.zip

I don't know if it works. UT Video Codec works for sure, and has 32-bit, 64-bit versions .

You can get a free version of cineform from go pro (it's a vfw version , so it will show up in vdub)

Thanks,

I will try the huffvuv 64 bit. Are the tutorial about how to use UT Video Codec. Is just installing it and it is ready to go, or I need to use it with other software?

UT Video Codec will show up in vdub or any VFW application , so you would have to load your video in vdub (mp4 is not so easy to load in vdub, but you can try vdub's directshow import plugin, or avisynth to load it - I know, you're unfamilar with avisynth, but it just takes 1 line)

[suppafreak]

I am completely in the dark about vdub or avisynth. Are there specific tutorials?

Thanks

[suppafreak]

I found this tutorial https://forum.videohelp.com/threads/225793-How-to-open-MP4-MKV-WMV-RM-MOV-OGM-with-any-editor-encoder

but it says in the thread that it does not work with premiere.

[poisondeathray]

That's an old tutorial , you can do basically the same thing with avfs , and frameserve into premiere (no need for huge intermediate files - if you use huffyuv or ut or similar they will be ~10x the size)

You have to mount the .avs file

Here are related instructions, skip to the mounting part
http://forum.doom9.org/showthread.php?t=163647

But I would use FFMpegSource2 instead of DirectShowSource , because the former is frame accurate

I appreciate everyone's help. Obviously most of you have done this before and have vast experience. Me on the other hand not so much.

So far, as I understand, I need to do the following:

1. create an .avs file and mount it. However, I have no clue what program to use.
2. Mount it using these instructions http://forum.doom9.org/showthread.php?t=163647

what comes after that?

Yes, you create an .avs file with avisynth , install the ffmpegsource plugin in avisynth plugins folder (you need the .dll and .avsi)

e.g Open a text file in notepad , change paths & file names to match, save it, rename extension from .txt to .avs

FFMpegSource2("PATH\youtubevideo.mp4", atrack=-1)


Then you mount the avs, and there will be a "dummy" AVI file created. TO premiere and any other program, that "dummy" AVI will look like a real video, and you can import that into any program



Or you can use the avs CS5 import plugin , but you need 64bit avisynth and plugins (most avisynth plugins are still 32bit). Eitherway, the key part is the avisynth script

OK new stumbling block.

I created a .avs file and wanted to mounted. According to the instructions here http://forum.doom9.org/showthread.php?t=163647 I just new to right-click on the .avs file and select quick mount. I do not see the quick mount selection when I right click on the .avs file.

If quick mount selection does not exists I need to download and install AVFS is a virtual file system. In the installation instruction is says the following:

Installation ------------ Install the latest Pismo File Mount Audit Package from http://www.pismotechnic.com/download/ .

Copy avfs.dll to a folder of your choosing. The c:\windows folder will work.
From a cmd prompt run: pfm register c:\windows\avfs.dll

If you later want to disable or uninstall AVFS, from a cmd prompt run: pfm unregister c:\windows\avfs.dll then delete the avfs.dll file.

not sure what "pfm" is but it is not recognized.


I have a problem registering the dll. The specified command does not work in Win 7 64bit.

[poisondeathray]

Did you follow the instructions in the readme ?

There should be a mount and quick mount option in the context menu (right click) , it works fine in win7 x64

IIRC some people had problems with certain versions of Pismo File Mount Audit Package , you might try an older version, there is an archive available

[suppafreak]

Yes copied the avfs.dll to c:\windows folder.

Opened cmd and did the following: C:\>pfm register c:\windows\avfs.dll

got the following error: 'pfm' is not recognized as an internal or external command, operable program or batch file.

[poisondeathray]

not sure... do you have permissions or logged in as administrator ?

you can try asking the developer at that doom9 thread

[suppafreak]

I run cmd as administrator

I also tried this: C:\Windows\system32>regsvr32.exe c:\windows\avfs.dll
and this: C:\Windows\SysWOW64>regsvr32.exe c:\windows\avfs.dll

but get this error: The module "c:\windows\avfs.dll" was loaded but the entry point DLLRegister was not found. Make sure that "c:\windows\avfs.dll" is a calid DLL or OCX file then try again.

[poisondeathray]

try putting quotes around it " "

pfm register "PATH\avfs.dll"

[suppafreak]

same error

C:\Windows\System32>pfm register "c:\windows\avfs.dll"
'pfm' is not recognized as an internal or external command,
operable program or batch file.

where is pfm supposed to be located?

[poisondeathray]

Try different older package
http://www.pismotechnic.com/download/archive/

pfm is part of the Pismo File Mount (=PFM) package, but I don't know it's location. It needs to be installed first

[suppafreak]

I was able to create avi file using .avs. However, not sure why, the icon has and gray X. Also when I load the file in premiere, the video does not display. When the file is loaded it show sound icon, like it is a sound file only. Once again I can open the file in windows media player.

[poisondeathray]

do you mean you got it mounted, with the "dummy" avi ?

what was the problem with the registration ?

Add ConvertToRGB32() to the end of your script

[suppafreak]

Yes load the dummy file in Premiere, but the file shows up only as audio file.

is it like that?

FFMpegSource2("F:\video\xploratv.mp4", atrack=-1)
ConvertToRGB(clip, matrix="rec709")
