I don't know what I'm doing anymore.
I'm trying to convert an MP4 video I recorded with Open Broadcaster Software to a series of PNG frames. I first tried Adobe Media Encoder CS5. Unfortunately, I found the exported image quality unsatisfactory.
Here are some examples:
Below is a screenshot of the movie I took with VLC Media Player.
In my opinion, the quality here is flawless. Zoom in -- the pixel edges are quite pronounced.
Below here is a frame I exported with Adobe Media Encoder.
If you zoom in, you'll notice annoying little pixel echos. I feel like the image has been ever so slightly scaled and then re-scaled.
Here is a comparison. You'll have to open the image in a new tab to see it.
Notice the VLC screenshot is quite crisp and precise. I'd like to see that same pixel precision on every frame I export.
It was quite apparent I was losing quality with AME.
I tried many, many times to match the source video's settings when I exported. No luck.
It was already clear to me VLC was capable of outputting the frames I needed with the quality I wanted.
I mean, it took perfect video screenshots.
So I tried to export every frame of the movie using VLC's Scene video filter.
I set the 'Recording ratio' to '1' so that VLC would export every single frame.
Apparently, VLC is unable to export every single frame. Whenever it tries to do this, most of
the exported frames are corrupt and empty. This bug has been known since 2008, and
still remains unfixed.

After this, I tried numerous different programs to no avail. I tried AVS Video Editor,
VirtualDub, VirtualDubMod, MediaCoder, Convert MP4 to Any and a few others I've
None of them can convert an MP4 video to a series of lossless PNG images.
Next I looked at ffmpeg.
This thing is beyond me. I have to use the Command Prompt?
People say it can do the job, but I have no idea how to work it.
Well, to summarize, I need a program that can export either .png images or .tiff images from an MP4 video.
I want a program that can do this with zero compression. Does anyone know of one? VLC would work if it could just
export every frame.
I just want a series of perfect, crystal-clear screenshots. I'd appreciate any help.
