x264 vs x265??

[gonca]

Could use help creating the avs script

[poisondeathray]

@gonca , are you more comfortable with commandline e.g ffmpeg perhaps ?

I think ffmpeg can read hevc now as well , just replace input1.ext , input2.ext

This gives aggregate PSNR, PSNR Y, PSNR U, PSNR V, with MSE Y, MSE U, MSE V

ffmpeg -i input1.ext -vcodec rawvideo -filter:v "movie=input2.ext,setpts=PTS-STARTPTS[main];[in][main]psnr=f=logfile.log" -f rawvideo -y /NUL

for ffms2 you need to create avs script for each file. It's simple one line , save it, e.g. video1.avs , video2.avs

You need to install avisynth, ffms2 plugin is external download (put the .dll in the avisynth plugins folder to autoload)
http://code.google.com/p/ffmpegsource/

For MSU, I would use seekmode=0, it's more frame accurate . Problems with PSNR/SSIM testing when video frames do no coincide (you get faulty low values)

e.g. video1.avs might say:
FFVideoSource("video1.ext", seekmode=0)

video2.avs might say:
FFVideoSource("video2.ext", seekmode=0)

This script can't open the MKV. A little help with what I screwed up

[Selur]

Looks fine,.. assuming no typos in the file&path names

[Selur]

wrong thread.

[gonca]

No typos

[Selur]

Then where do you try to open it? Normally Avisynth throughs some sort of error when it fails,... (also depending on the ffms2.dll it might not be a C-Plugin, but a normal Plugin)

[poisondeathray]

Yes, post any error messages . Can you open "normal" files, even youtube MP4 download , other MKV's etc.... ? or is it just problem with HEVC ?

Try this version

[gonca]

Downloaded portable version of MPC-BE. Plays the actual file. Hangs trying to open the avs script. Switched the plugin to the one linked by poisondeathray.
Corrected script attached

[Selur]

The version poisondeathray linked to is a C-Plugin version.

[gonca]

Changed the script back to the C version. No change

I attached the files if someone else wants to give it a shot.

[Selur]

Since you also use Hybrid, do the following:

1. uninstall Avisynth 2.5 (no clue why anyone would use it and not Avisynth 2.6a5)
2. install Avisynth 2.6a5 (http://forum.doom9.org/showthread.php?p=1644457)
3. replace the avisynth.dll with the one from inside Hybrid folder
4. open source file in Hybrid
5. press: Filtering->Avisynth->Show current Avisynth script
6. copy the content of the AvisynthScriptView into a new file with .avs extension
7. try to open that file with MPC-BE or avsViewer (avsViewer "Path to file")

Cu Selur

Ps.: also still no clue what the error message says assuming there is one

[gonca]

Original file being uploaded to a file sharing site. It exceeds VH limits (will take over an hour)

https://media.xiph.org/video/derf/y4m/

This site has the original file if anyone is interested

[El Heggunte]

<Off-Topic>

Yes, derf@xiph might and should compress their sample files, sadly he/she knows that "everybody" has unlimited broadband speeds and endless storage space

</Off-Topic>

[poisondeathray]

Does it just hang or any error message ?

Install avisynth 2.6.x like selur said above. You need that for the Cplugin versions

You can check/preview .avs scripts in vdub as well

[LigH.de]

@ EH:

But Y4M is possibly the only rather platform independent format. Which other lossless compression would you recommend instead? An external tar.z / tar.gz / tar.bzip2 / PKZIP / 7zip (which exact subformat) archive – which need additional space to unpack later – or AVC lossless as MP4, or Huffyuv / Ut / FFV1 AVI?

[Selur]

You need that for the Cplugin versions

Are you sure? I thought that LoadCPlugin was introduced before 2.6, see: http://forum.doom9.org/showthread.php?s=&threadid=58840

[poisondeathray]

You need that for the Cplugin versions

Are you sure? I thought that LoadCPlugin was introduced before 2.6, see: http://forum.doom9.org/showthread.php?s=&threadid=58840

Yes, I meant was that ffms2 CPlugin version has support for additional colorspaces and avisynth 2.6 is a requirement

[El Heggunte]

@ EH:

But Y4M is possibly the only rather platform independent format. Which other lossless compression would you recommend instead?

So you think Y4M is a compressed format

Anyway, 7z and rar can compress nicely both Y4M files and BMP image sequences.

[vhelp]

LigH.de, you can extract a 7z file w/out space (or extra space) limitation if you use the Copy-to function of the extract. that is how i extract files on my limited hdd which fluctuates around 300mb. right now, it is at 151mb. and most people here know that i run xp on fumes. i extract to external hdd's.

No error messages. just displays message "opening"

Here is a link to the original file from my mediafire account

Will try Selur's suggestion

[gonca]

Hybrid can't see hevc in mkv container. Will have to re-encode to mp4

[Selur]

Will have to re-encode to mp4

remuxing should be enough

Hybrid can't see hevc in mkv container.

Ah, totally forgot about that,.. (came up with a workaround a few days ago)

[gonca]

Re-encoding the original is quick enough

[gonca]

Used Hybrid's AviSynth script, and MPC hangs on opening it

[gonca]

Here is the script

[Selur]

You have to wait a bit, when you open that script the first time, since the content first needs to be indexed.
Enable 'Filtering->Avisynth->Misc->LibavVideoSource instead of FFmpegSource' and then use that script.

[jagabo]

Where are you guys getting an ffms2 build with HEVC support?

[gonca]

Here is a 7z compressed version of the original

[Selur]

latest from qyot27: http://forum.doom9.org/showthread.php?p=1685186#post1685186 contains an updated libav and thus supports hevc
