Utility to compare different encodings

[Lele-brz]

Hi all,
Some time ago I wrote a simple application (Win32 only) to visually compare two different encodings.
Basically it's just a player that plays two different videos and keeps them syncronyzed. So it's possible to switch from one to the other and determine the visual improvements at full screen.
I needed it to compare different profiles, bitrate and resolution to determine what could I consider my encoding profile.

The GUI is very minimal now, when launched just select the two video to compare, then you can click to switch from one file to the other.
F goes fullscreen and back.
Space pause/play the video
Right click performs seeking (ffplay way).

Ok, hope this can help.
Bye

Thanks

what does the grey window w/blue graph track (bavtest I think it was) ?

Hi,
the other app just plays the video using a wrapper of FFmpeg.
In the grey window I just display the file accesses, that made me understand that when Mp4Box multiplexed the interleaving is not as expected. It's supposed to be 0.5 sec but I could see that the accesses to the file are very far one to the other, I guess to retrieve audio packets that are far from the current video packet.
Matroska file instead have a perfect interleaving.
This is useful if you consider http streaming of the file.

Lele-brz,

Thank you for this nice and easy utility. How do you know which video is the one playing at any given time? I see no file name indicators.

Thanks!

[Razorholt]

Nice improvement indeed, Lele-brz! Like Chainring mentioned above, how do you know which video you're playing?

Thanks,

The red block seems to be the first one you open and the blue block is the second.

[Razorholt]

The red block seems to be the first one you open and the blue block is the second.

hmm... I don't see any colored blocks. The only think I notice is a white block upper left but it doesn't change when I'm swaping videos.

Same for me; only a white block.

can you add m2ts as input please.

[cyberbeing]

Odd, I definitely have a red block that changes to blue when I click it.

I'm using a nVidia 7800GTX 512 with the 175.51 driver on XP SP3 32bit.

Do you guys have an ATI card or are you using Vista or something?

[Zwitterion]

Thank you for this tool! The synchronisation is very good... no flickering when switching between the two vids as in some other applications.

Some suggestions:
- a version without installer would be nice
- the second open window should remember the location of the first video instead of defaulting to C:\ again
- some more controls (like Alt+Enter for fullscreen, Esc for shutdown, cursor keys for next/previous frame in pause mode)

Also I don't have the white block issue (XP SP2, 6800GT).

It seems to support everything that ffmpeg plays, just copy the filename into the 'open' window. That should work...

[Lele-brz]

Thanks for your suggestions.
That was just a test application for determing the real encoding improvements when watching a video at full screen (with OpenGL rendering).

My intention is to make it more user-friendly and with some additional features.

Yes, for determing the video played I just draw a block on the top left (red and blue), I guess on some video card this is not working.
I tried on different pc without having the white block issue.
I'll investigate more...

@survivant001
Yes, many formats are supported but I just put some of the most common file extensions, if you put *.* when opening a file you can open even other files extensions.

cool, I'll try it

you can use AVSP too. just need to create a .avs and it's really simple to compare videos in tab

With AvsP you can compare still images from two different scripts/movies.

With lelebrz's tool, you can play two different videos and switch from one to the other on the fly, if I understood correctly ... I still have to try it :p

[Lele-brz]

Yes, you can do something similar using AviSynth.
I used a script to display half video on one side and the other video on the other side (if needed I can post, it's quite simple but I don't want to go off topic).
To me it's more easy to spot the differences when switching on the entire video or pause and compare frame.
Probably it's possible to do the same using AviSynth but I don't know if you can handle mouse/keyboard inputs at run time.

Another thing I would like to add is to diplay x264 encoding parameters and higlights the different ones...

But it's not a good solution since the link is deleted when nobody uses it ...

[Schrade]

This is awesome. Makes comparing quality so much easier.

Link poofed again! Anybody able to drop it on a filesharer for a bit?!?

If the filesize is not "too big",
archiving the **** binary @ VideoHelp/tools/
would be a "safer choice".

I have uploaded it again here (http://sharebee.com/4b5ad0d5) but feel free to submit it to VideoHelp !

Thanks for Up ;)

This is a handy utility, so in an attempt to keep it accessible, I have mirrored the file here (http://www.interupload.com/files/0QEJT7GZ/SetupVideoCheck0.4.zip_links) and here (http://rapidshare.com/files/372870808/SetupVideoCheck0.4.zip) ;)

I have uploaded it again here (http://sharebee.com/4b5ad0d5) ...

Their mirrors are dying too (and DepositFiles is just annoying).

So I took the freedom to make a new mirror (http://www.ligh.de/software/SetupVideoCheck0.4.zip).

I doubt it will be continued?

[chainring]

A utility I still use to this day. Soooo darned handy. And a huge thanks to all of you that are mirroring/hosting it for others to enjoy.

[bxyhxyh]

Can it compare 10 bit and 8 bit videos?

[LigH]

All it does is playing two videos and switching between them. You do the comparing by looking at them. If it can play them, you can watch them and decide.

[SamKook]

I know it's been asked quite a while ago, but it might be helpful to others.

It can't properly handle 10bit videos, the colors are messed up.

It would be nice to get an updated version since it's not possible to just switch the dlls, but I doubt it will happen. Or if someone know a way to hack it it would also be nice.
