Need to convert 60fps footage to 30fps fully-preserved for YouTube

[Hero of Legend]

Okay so I replaced the text in the avs script where the video is with that, and nothing happened?

Also this file showed up in the folder where I put the script and video:

2013_7_26_23_49_19.mp4.ffindex

So something happened before.

[_Al_]

Yes, it looks like, that ffindex file was created there as soon as you load Avisynht script (with ffmpegsource2 line in it) into VirtualDub (or somewhere else like some encoder or something else while testing), the longer video, the longer it takes to create that index file, so it freezes for a moment while that file is creating, so it looks like ffmpegsource should work. Not sure why it is not working in VirtualDub now.

DirectShowSource does not create that index file. Did you try to load that avisynth script with that DirectShowSource line into VirtualDub?

[Hero of Legend]

I don't know, I can't find where it would day if it was 32 or 64 bit. Should I get the 32 bit one?

[_Al_]

yes 32 bit VirtualDub https://www.videohelp.com/tools/Virtualdub , unless it specifies it is 64bit download there, it is 32bit

Edit: Downloaded the ffms2.dll and ffms2.avsi plugins and put them in the plugins folder in the Avisynth folder, again didn't work in VD but it gave me a different message.

Always post the error message and the exact script used. Perhaps FFMPEGSource2 worked to open the video and now it's a different problem, maybe with QTGMC. The error message should say.

[_Al_]

You can always delete that line with QTGMC in that Avisynth script and load only one line Avisynth script and test it so it is not QTGMC, but those error messages are quite clear that it is line 1 that it is troublesome.

The message was:

Avisynth open failure:
DirectShowSource:Could not open as video or audio.

Video returned: "DirectShowSource: couldn't open file 2013_7_26_23_49_19.mp4:
Cannot play back the file: The format is not supported."

Audio returned: "DirectShowSource: couldn't open file 2013_7_26_23_49_19.mp4:
Cannot play back the file: The format is not supported."

(C:\Users\******\Desktop\New Folder (7)\Video\New Text Document.avs, line 1)

And it should be 32bit VD.

can you capture some 5-10s clip like you did with that tested clip and upload it here or post some info about your captured file, use mediainfo utility for that

I have clips on YouTube already I can share if that's fine, I can use mediainfo.

codec id as 3gp4 - not sure if that could be problematic, but there is variable frame rate - that one usually can cause some problems, but if in this situation, not sure,..., short clip would be more handy,I can try it with real file and troubleshoot if it is that video file that is troublesome or just system in your PC doesn't like something (I'd be not real help to troubleshoot system)

[Hero of Legend]

Oh you're offering a test yourself? That's kind of you, makes sense since you can play with it and figure out the ideal solution.

I can just upload the whole thing, but I can clip it and make it a small file-size, but not at the best quality obviously, but ideal for your tests.

[_Al_]

I thought that it is some kind of capture, easily to duplicate again, small sample.

[Hero of Legend]

Oh sure, I can make another moment-long recording. All the ones I have on me are close to 10 minutes, I'll have one by morning EST. Can't right now.

Oh, and I just realized I never said what I used to record; it's the Hauppauge HD PVR 1212. I'm recording to the "Xbox 360" mp4 file, there are two other options:

So that info will surely help as well. I record generally in 480p via Component.

[DARR-of_the-DEAD]

you guys made this hard
why not just use acrsoft showbiz drag in drop file into showbiz select produce then select upload to youtube it will convert then file from 60 to 30 for you.
i don't think showbiz is free from arcsoft, but it is from hauppauge for pvr's
come with the drivers for the hd pvr 2 and a Personal Logo applications but after installing just uninstall the pvr 2 driver and the Personal Logo applications. heres the link: http://www.hauppauge.com/site/support/support_hdpvr2-gaming.html
download file HD PVR 2 CD 1.6
you may have to reinstall the correct drive for your pvr 1212

you can also use ezvid, but ezvid will make you add music to you video, but you can download or make a blank track and use it then you don't have to worry about the music part. http://www.ezvid.com/

both of these will work great

[jagabo]

you guys made this hard

The OP is looking for something better than simple decimation.

[DARR-of_the-DEAD]

why?..... he's not going to get any better quality.

[jagabo]

why?..... he's not going to get any better quality.

Because 30 fps is very flickery. He's looking for methods of reducing that flicker. For example, by adding motion blur.

sure it not hes bite-rate when recording the video isn't the problem?

i got this problem with my hd pvr 2 when i don't have the the bitrate set to high when making the recording.
when i first got my pvr i had this issues and did some research:
"if you plan to upload vids on YouTube, YouTube will reduce the frame rate to 30 FPS. Since a video on YouTube won't be the same quality as your recording, the bitrate of your recording should be no higher than 5 Mbps." i use 4Mbps.

and i can upload right from the YT page.

[_Al_]

This topic is not about quality (only if op brings it up), this is about "fluidity" of that video. To get fluid feeling watching it after half of the frames are gone. Especially if something moves with fast vector speed in front of camera etc. where that QTGMC helps and smooths it out by adding motion blur. Youtube only disregards every other frame upon upload of 60p.

Talking about quality, to get more quality out of YouTube, you have to give it the best quality as possible, where bitrate is quite important variable for quality in video. So that research you did is not that quite right. It is proven that even manual good upscale improves overall quality on YouTube , that goes for SD resolutions (it is used in this thread) but that's another story, that Avisynth script would have to have couple more lines, it adds up processing time also, where that QTGMC adds up processing time quite remarkably in the first place.

[DARR-of_the-DEAD]

ok

[fjollon]

Hello,

Don't mean to steal the thread but I have basically the same task at hand as the OP. The only difference is that my source file is not an mp4 but an avi (a Fraps video at 60 FPS from a game). I made a slight change to the script from page 1 in an attempt to get it to work with an avi, but I am getting an error as seen in the attached picture.

(Avisource ("C:\Users\Jonas\Desktop\new test\fisk2.avi")
QTGMC( Preset="medium",InputType=1, FPSDivisor=2, ShutterBlur=1, ShutterAngleSrc=30,  ShutterAngleOut=360 )

I have installed (in the avisynth plugin folder) all the required plugins listed in the QTGMC documentation.

I don't know how many hours I have spent the last few days to find a good script for this, but it is a few.

Any help would be greatly appreciated.

[poisondeathray]

@fjollon:
Add

ConvertToYV12(matrix="rec709")

Right after AVISource() , before QTGMC()

Also, AVISource should not be have open bracket before

Avisource ("C:\Users\Jonas\Desktop\new test\fisk2.avi")
ConvertToYV12(matrix="rec709")
QTGMC( Preset="medium",InputType=1, FPSDivisor=2, ShutterBlur=1, ShutterAngleSrc=30, ShutterAngleOut=360 )

[poisondeathray]

One potential problem with the motion blur techniques, is static overlays (eg. HUD displays, ammo indicators, scores etc...) sometimes get distorted as object move beneath them (because they are semi transparent, and the motion vector analysis gets "confused" as there where object boundaries are) . It's usually not that bad with QTGMC, but one way around that is to use an mask overlay . Or you can experiment with the settings, or use the normal frame blend method

[fjollon]

Thanks a bunch!!

This worked great. The bracket before AVISource was a typo made when I posted and was not in the actual script.

I made a quick test and it looks better than just "SelectEven()". I guess I will be doing some tests with the settings starting with ShutterAngleSrc=0.

I do have a semi transparent menu in the top left corner, but it was not affected at all.

Thanks again!!

I tried, but I get millions of errors in avisynth

[newpball]

I'm recording games and I have found a solution, it's just not very practical and efficient.

I found VirtualDub and so far, I've only tried interlacing the videos so they're in 30fps but the frames are blended to retain the feel of 60fps.

But of course I get the damn lines, so my solution was to use another program to first upscale the video to say 2560x1440 and then interlace it, then bring it down to 1280x720 to eliminate the lines, but the whole process makes my computer chug and takes up a lot of GBs on my HDD.

And I'm sure quality is lost in the process.

What I need is a program that can blend 60fps to 30fps automatically with no lines and retain the picture quality.

Preferably free software? I'm sure VirtualDub or some other program has the capability, I just can't find it. And I'm not a tech wizard so telling me to edit scripts and code is going to fly over my head.

Thanks. Any ideas?

You are butchering the video!

First of all why cut a video in half in the first place?
Anyway, Youtube supports 60fps.

Not a very helpful post. Didn't you read the kinds of information needed so help could be provided, from earlier in the thread? Script? Error messages?

Or make it 60fps if it isn't already. Or let YouTube decimate it to 30fps for you.

This is error message. I want to fix stuttering created when I convert 60fps to 30fps, meabe frame dropping too.

Did you install the other DLLs needed for QTGMC to work:
